  1. Hola gavi23 Por lo que dices supongo que ambos pisos están en el mismo edificio y tienen visibilidad entre si. Si esto es así podrias usar AP's con WDS que te permitiesen enlazar la red del piso 3 con la del piso 9. Estos AP's los podrías poner en el exterior de manera que ambos se viesen entre si y llevar un cable al Switch de cada piso. Te pego un enlace a un gráfico con la solución que te digo. http://img177.imageshack.us/my.php?imag ... d10yg5.jpg Salu2
  2. Hola a los dos, Cardel el tema de unir varias líneas se conoce como Bonding, busca en Google Bonding ADSL o Routers Bonding ADSL y encontrarás gran cantidad de información sobre el tema. Salu2
  3. Hola Buffer_overflow Lo que quieres hacer es posible, aunque no recomendable. Lo que quieres es tener dos subnets sobre el mismo dominio de Broadcast, lo cual te puede originar problemas a la hora de usar aplicaciones que funcionen por Broadcast (por ejemplo no podrías poner ambas redes por DHCP) La forma correcta de hacerlo sería con un Switch gestionable en el que puedas definir VLAN's, de esta manera las dos redes estarían separadas (cada una en su VLAN) y no tendrías ningun tipo de problemas. Si ademas quieres que esas dos redes se viesen entre si, podrías usar un Switch de capa 3 que te permitiría enrutar entre ellas. Salu2
  4. Hola Tentaciones A la primera te contesto yo , no puedes llegar a el porque está en un rango de IP's distinto al tuyo, por lo que dices tu tienes una 192.168.2.x y el está en la 192.168.1.x por lo que es inalcanzable para tu equipo. Puedes ponerle al equipo una IP secundaria de dicho rango (192.168.1.x), cambiarsela al WRT54G por una del rango 192.168.2.x y despues ya le podrías quitar la IP secundaria al equipo y acceder al WRT54G por la IP que le hayas puesto. Salu2
  5. Hola a los dos, pecos, yo estoy con Z03Z en que si puedes hacerlo cableado mejor que mejor, el rendimiento y la seguridad van a ser mucho mayores que por WiFi. Por WiFi lo podrías hacer, bastaría con poner tantos puntos de acceso como necesites para cubrir la totalidad del local enlazados entre si en modo repetidor (para que sea una sola red). Lo normal, sería comprar un primer punto de acceso y colocandolo en diferentes puntos del local mirar la cobertura con un equipo y de esta manera hacerte un plano donde tuvieses los niveles de cada zona. Pero como te decía al principio yo me iría a cable. Salu2
  6. Hola a todos, Si no me equivoco WinGate te permite definir porque conexión quieres que vayan determinados puertos o servicios (aunque realmente creo que no hace un balanceo de carga como tal), pero para lo que tu quieres podría servirte. Salu2
  7. Hola de nuevo, Perdona tu tambien por el retraso, me temo que no te voy a poder ayudar mucho ya que no conzco ese router, debes de buscar algo como Static Routes, mira por la configuración de LAN a ver si lo encuentras, de todas formas dime mas o menos las opciones que veas que puedan estar relacionadas y a ver si lo encontramos. Salu2
  8. Hola pulgares, Perdona por el retraso en responderte, al final el tiempo de desconexión ha sido mas del que yo creia (como siempre). Bueno, ahora que tienes ya la IOS cargada haz lo siguiente: Conectate por Telenet al router y pegame la configuración que tienes. Conectate por hiperterminal y arranca el router, verás que salen mensajes de las interfaces y lo que van haciendo, copiamelos y pegamelos aquí a ver si vemos lo que dice el Dialer. Salu2
  9. Hola Pulgares, Te pasa porque lo tienes mal escrito, no es tftdnld es tftpdnld. Prueba y me cuentas, si ves que tardo un poco en contestarte es porque voy a estar unos días sin conexión, pero en cuanto vuelva te contesto. Salu2
  10. Hola Pulgares, Vamos a ir por partes ya que me temo que le has borrado el sistema operativo. En primer lugar dime si tienes alguna IOS para el 827, si no la tienes dime por privado una dirección de correo a la que enviartela y despues vemos como cargarla. Salu2
  11. Hola de nuevo, Te he preparado un gráfico de como lo haría yo para que ambas redes se vean entre si y ambas tengan acceso a Internet. Tendrás que adaptar las IP's a las que tengas puestas pero me imagino que te harás una idea de como configurarlo. Te pego el enlace y si te quedan dudas las vemos http://img133.imageshack.us/img133/534/ ... ed97lq.jpg Salu2
  12. Vale, Mañana te preparo un gráfico y te lo envío Salu2
  13. Hola de nuevo, No me refiero al rango de esa red, sino al rango de las redes remotas a las que accedes a través del Cisco
  14. Hola hlopezrd Necesitaría saber una cosa, el rango de direcciones al que accedes por el Cisco 800, ¿lo sabes? si no es así el acceso a Internet de los de la red 172.x.x.x va a ser problemático. Dime si lo sabes y te preparo un gráfico de como tienes que conectar todo. Salu2
  15. Hola Pulgares ¿Que le has borrado?, te pego un procedimiento para arrancar desde Rommon siempre que no te hayas cargado el IOS, prueba con esto y si no te arranca te envío una IOS y te digo como cargarla. Tranquilo que seguro que tiene solución.

The ROM monitor firmware runs when the router is powered up or reset. The firmware helps to initialize the processor hardware and boot the operating system software. You can use the ROM monitor to perform certain configuration tasks, such as recovering a lost password or downloading software over the console port. If there is no Cisco IOS software image loaded on the router, the ROM monitor runs the router. This appendix contains the following sections: Entering the ROM Monitor ROM Monitor Commands Command Descriptions Disaster Recovery with TFTP Download Configuration Register Console Download Debug Commands Exiting the ROM Monitor Entering the ROM Monitor To use the ROM monitor, you must be using a terminal or PC that is connected to the router over the console port. Refer to documentation listed in the Obtaining Documentation section of this guide for information on connecting your router to a PC or terminal. Perform these steps to configure the router to boot up in ROM monitor mode the next time it is rebooted. Command Purpose Step 1 enable If an enable password is configured, enters the enable command and the enable password to enter privileged EXEC mode. Step 2 configure terminal Enters global configuration mode. Step 3 config-reg 0x0 Resets the configuration register. Step 4 exit Exits global configuration mode. Step 5 reload Reboots the router with the new configuration register value. The router remains in ROM monitor and does not boot the Cisco IOS software. As long as the configuration value is 0x0, you must manually boot the operating system from the console. See the boot command in the "Command Descriptions" section in this appendix. After the router reboots, it is in ROM monitor mode. The number in the prompt increments with each new line. -------------------------------------------------------------------------------- TimeSaver Break (system interrupt) is always enabled for 60 seconds after the router reboots, regardless of whether it is set to on or off in the configuration register. During this 60-second window, you can break to the ROM monitor prompt by pressing the Break key. -------------------------------------------------------------------------------- ROM Monitor Commands Enter ? or help at the ROM monitor prompt to display a list of available commands and options, as follows: rommon 1 > ? alias set and display aliases command boot boot up an external process break set/show/clear the breakpoint confreg configuration register utility cont continue executing a downloaded image context display the context of a loaded image cookie display contents of cookie PROM in hex dev list the device table dir list files in file system dis display instruction stream dnld serial download a program module frame print out a selected stack frame help monitor builtin command help history monitor command history meminfo main memory information repeat repeat a monitor command reset system reset set display the monitor variables stack produce a stack trace sync write monitor environment to NVRAM sysret print out info from last system return tftpdnld tftp image download unalias unset an alias unset unset a monitor variable xmodem x/ymodem image download Commands are case sensitive. You can halt any command by pressing the Break key on a terminal. If you are using a PC, most terminal emulation programs halt a command when you press the Ctrl and the Break keys at the same time. If you are using another type of terminal emulator or terminal emulation software, refer to the documentation for that product for information on how to send a Break command.

If you do not enter a filename, this command will boot this first image in Flash. Disaster Recovery with TFTP Download The standard way to load new software on your router is using the copy tftp flash privileged EXEC command from the Cisco IOS software command-line interface (CLI). However, if the router is unable to boot the Cisco IOS software, you can load new software while in ROM monitor mode. This section describes how to load a Cisco IOS software image from a remote TFTP server to the router Flash memory. Use the tftpdnld command only for disaster recovery because it erases all existing data in Flash memory before downloading a new software image to the router. TFTP Download Command Variables This section describes the system variables that can be set in ROM monitor mode and that are used during the TFTP download process. There are both required variables and optional variables. -------------------------------------------------------------------------------- Note The commands described in this section are case sensitive and must be entered exactly as shown. -------------------------------------------------------------------------------- Required Variables These variables must be set with these commands before using the tftpdnld command: Variable Command IP address of the router. IP_ADDRESS= ip_address Subnet mask of the router. IP_SUBNET_MASK= ip_address IP address of the default gateway of the router. DEFAULT_GATEWAY= ip_address Variable Command IP address of the TFTP server from which the software will be downloaded. TFTP_SERVER= ip_address The name of the file that will be downloaded to the router. TFTP_FILE= filename Optional Variables These variables can be set with these commands before using the tftpdnld command: Variable Command Configures how the router displays file download progress. 0—No progress is displayed. 1—Exclamation points (!!!) are displayed to indicate file download progress. This is the default setting. 2—Detailed progress is displayed during the file download process; for example: Initializing interface. Interface link state up. ARPing for 1.4.0.1 ARP reply for 1.4.0.1 received. MAC address 00:00:0c:07:ac:01 TFTP_VERBOSE= setting Number of times the router attempts ARP and TFTP download. The default is 7. TFTP_RETRY_COUNT= retry_times Amount of time, in seconds, before the download process times out. The default is 2,400 seconds (40 minutes). TFTP_TIMEOUT= time Whether or not the router performs a checksum test on the downloaded image: 1—Checksum test is performed. 0—No checksum test is performed. TFTP_CHECKSUM=setting Using the TFTP Download Command The steps described in this section should be performed while in ROM monitor mode. -------------------------------------------------------------------------------- Step 1 Use the appropriate commands to enter all the required variables and any optional variables described earlier in this section. Step 2 Enter the tftpdnld command as follows: rommon 1 > tftpdnld -r -------------------------------------------------------------------------------- Note The -r variable is optional. Entering this variable downloads and boots the new software but does not save the software to Flash memory. You can then use the image that is in Flash memory the next time you enter the reload command. -------------------------------------------------------------------------------- You will see output similar to the following: IP_ADDRESS: 1.3.6.7 IP_SUBNET_MASK: 255.255.0.0 DEFAULT_GATEWAY: 1.3.0.1 TFTP_SERVER: 223.255.254.254 TFTP_FILE: c806-sy-mz Invoke this command for disaster recovery only. WARNING: all existing data in all partitions on flash will be lost! Do you wish to continue? y/n: [n]: Step 3 If you are sure that you want to continue, enter y in response to the question in the output: Do you wish to continue? y/n: [n]:y The router begins to download the new file. Enter Ctrl-C or Break to stop the transfer before the Flash memory is erased. -------------------------------------------------------------------------------- Configuration Register The virtual configuration register is in nonvolatile RAM (NVRAM) and has the same functionality as other Cisco routers. You can view or modify the virtual configuration register from either the ROM monitor or the operating system software. Within ROM monitor, you can change the configuration register by entering the register value in hexadecimal format, or by allowing the ROM monitor to prompt you for the setting of each bit. Changing the Configuration Register Manually To change the virtual configuration register from the ROM monitor manually, enter the command confreg followed by the new value of the register in hexadecimal, as shown in the following example: rommon 1 > confreg 0x2101 You must reset or power cycle for new config to take effect rommon 2 > The value is always interpreted as hexadecimal. The new virtual configuration register value is written into NVRAM but does not take effect until you reset or reboot the router. Changing the Configuration Register Using Prompts Entering confreg without an argument displays the contents of the virtual configuration register and a prompt to alter the contents by describing the meaning of each bit. In either case, the new virtual configuration register value is written into NVRAM but does not take effect until you reset or reboot the router. The following display shows an example of entering the confreg command: rommon 7> confreg Configuration Summary enabled are: console baud: 9600 boot: the ROM Monitor do you wish to change the configuration? y/n [n]: y enable "diagnostic mode"? y/n [n]: y enable "use net in IP bcast address"? y/n [n]: enable "load rom after netboot fails"? y/n [n]: enable "use all zero broadcast"? y/n [n]: enable "break/abort has effect"? y/n [n]: enable "ignore system config info"? y/n [n]: change console baud rate? y/n [n]: y enter rate: 0 = 9600, 1 = 4800, 2 = 1200, 3 = 2400 [0]: 0 change the boot characteristics? y/n [n]: y enter to boot: 0 = ROM Monitor 1 = the boot helper image 2-15 = boot system [0]: 0 Configuration Summary enabled are: diagnostic mode console baud: 9600 boot: the ROM Monitor do you wish to change the configuration? y/n [n]: You must reset or power cycle for new config to take effect Console Download You can use console download, a ROM monitor function, to download over the router console port either a software image or a configuration file. After download, the file is either saved to the mini-Flash memory module or to main memory for execution (image files only). Use console download when you do not have access to a Trivial File Transfer Protocol (TFTP) server. -------------------------------------------------------------------------------- Note If you want to download a software image or a configuration file to the router over the console port, you must use the ROM monitor command. -------------------------------------------------------------------------------- -------------------------------------------------------------------------------- Note If you are using a PC to download a Cisco IOS image over the router console port at 115,200 bps, ensure that the PC serial port is using a 16550 universal asynchronous transmitter/receiver (UART). If the PC serial port is not using a 16550 UART, we recommend using a speed of 38,400 or less when downloading a Cisco IOS image over the console port. -------------------------------------------------------------------------------- Command Description The following are the syntax and descriptions for the xmodem console download command: xmodem [-cyrx] destination_file_name c Optional. Performs the download using 16-bit cyclic redundancy check (CRC-16) error checking to validate packets. Default is 8-bit CRC. y Optional. Sets the router to perform the download using Ymodem protocol. Default is Xmodem protocol. The protocols differ as follows: Xmodem supports a 128-block transfer size. Ymodem supports a 1024-block transfer size. Ymodem uses (CRC)-16 error checking to validate each packet. Depending on the device that the software is being downloaded from, this function might not be supported by Xmodem. r Optional. Image is loaded into DRAM for execution. Default is to load the image into Flash memory. x Optional. Image is loaded into DRAM without being executed. destination_file_name The name of the system image file or the system configuration file. In order for the router to recognize it, the name of the configuration file must be router_confg. Follow these steps to run Xmodem: -------------------------------------------------------------------------------- Step 1 Move the image file to the local drive where the Xmodem will execute. Step 2 Enter the xmodem command. -------------------------------------------------------------------------------- Error Reporting Because the ROM monitor console download uses the console to perform the data transfer, error messages are only displayed on the console when the data transfer is terminated. If an error does occur during a data transfer, the transfer is terminated, and an error message is displayed. If you have changed the baud rate from the default rate, the error message is followed by a message telling you to restore the terminal to the baud rate specified in the configuration register. Debug Commands Most ROM monitor debugging commands are functional only when Cisco IOS software has crashed or is halted. If you enter a debugging command and Cisco IOS crash information is not available, you see the following error message: "xxx: kernel context state is invalid, can not proceed." The following are ROM monitor debugging commands: stack or k—produces a stack trace; for example: rommon 6> stack Stack trace: PC = 0x801111b0 Frame 00: FP = 0x80005ea8 PC = 0x801111b0 Frame 01: FP = 0x80005eb4 PC = 0x80113694 Frame 02: FP = 0x80005f74 PC = 0x8010eb44 Frame 03: FP = 0x80005f9c PC = 0x80008118 Frame 04: FP = 0x80005fac PC = 0x80008064 Frame 05: FP = 0x80005fc4 PC = 0xfff03d70 context—displays processor context; for example: rommon 7> context CPU context of the most recent exception: PC = 0x801111b0 MSR = 0x00009032 CR = 0x53000035 LR = 0x80113694 CTR = 0x801065e4 XER = 0xa0006d36 DAR = 0xffffffff DSISR = 0xffffffff DEC = 0xffffffff TBU = 0xffffffff TBL = 0xffffffff IMMR = 0xffffffff R0 = 0x00000000 R1 = 0x80005ea8 R2 = 0xffffffff R3 = 0x00000000 R4 = 0x8fab0d76 R5 = 0x80657d00 R6 = 0x80570000 R7 = 0x80570000 R8 = 0x00000000 R9 = 0x80570000 R10 = 0x0000954c R11 = 0x00000000 R12 = 0x00000080 R13 = 0xffffffff R14 = 0xffffffff R15 = 0xffffffff R16 = 0xffffffff R17 = 0xffffffff R18 = 0xffffffff R19 = 0xffffffff R20 = 0xffffffff R21 = 0xffffffff R22 = 0xffffffff R23 = 0xffffffff R24 = 0xffffffff R25 = 0xffffffff R26 = 0xffffffff R27 = 0xffffffff R28 = 0xffffffff R29 = 0xffffffff R30 = 0xffffffff R31 = 0xffffffff frame—displays an individual stack frame. sysret—displays return information from the last booted system image. This information includes the reason for terminating the image, a stack dump of up to eight frames, and, if an exception is involved, the address where the exception occurred; for example: rommon 8> sysret System Return Info: count: 19, reason: user break pc:0x801111b0, error address: 0x801111b0 Stack Trace: FP: 0x80005ea8, PC: 0x801111b0 FP: 0x80005eb4, PC: 0x80113694 FP: 0x80005f74, PC: 0x8010eb44 FP: 0x80005f9c, PC: 0x80008118 FP: 0x80005fac, PC: 0x80008064 FP: 0x80005fc4, PC: 0xfff03d70 FP: 0x80005ffc, PC: 0x00000000 FP: 0x00000000, PC: 0x00000000 meminfo—displays size in bytes, starting address, available range of main memory, the starting point and size of packet memory, and size of NVRAM; for example: rommon 9> meminfo Main memory size: 40 MB. Available main memory starts at 0x10000, size 40896KB IO (packet) memory size: 5 percent of main memory. NVRAM size: 32KB Exiting the ROM Monitor You must set the configuration register to a value from 0x2 to 0xF for the router to boot a Cisco IOS image from Flash memory upon startup or reloading. The following example shows how to reset the configuration register and cause the router to boot a Cisco IOS image stored in Flash memory: rommon 1 > confreg 0x2101 You must reset or power cycle for new config to take effect rommon 2 >boot The router will boot the Cisco IOS image in Flash memory. The configuration register will change to 0x2101 the next time the router is reset or power cycled. © 1992-2005 Cisco Systems, Inc. All rights reserved.

TFTP_TIMEOUT= time Whether or not the router performs a checksum test on the downloaded image: 1—Checksum test is performed. 0—No checksum test is performed. TFTP_CHECKSUM=setting Using the TFTP Download Command The steps described in this section should be performed while in ROM monitor mode. -------------------------------------------------------------------------------- Step 1 Use the appropriate commands to enter all the required variables and any optional variables described earlier in this section. Step 2 Enter the tftpdnld command as follows: rommon 1 > tftpdnld -r -------------------------------------------------------------------------------- Note The -r variable is optional. Entering this variable downloads and boots the new software but does not save the software to Flash memory. You can then use the image that is in Flash memory the next time you enter the reload command. -------------------------------------------------------------------------------- You will see output similar to the following: IP_ADDRESS: 1.3.6.7 IP_SUBNET_MASK: 255.255.0.0 DEFAULT_GATEWAY: 1.3.0.1 TFTP_SERVER: 223.255.254.254 TFTP_FILE: c806-sy-mz Invoke this command for disaster recovery only. WARNING: all existing data in all partitions on flash will be lost! Do you wish to continue? y/n: [n]: Step 3 If you are sure that you want to continue, enter y in response to the question in the output: Do you wish to continue? y/n: [n]:y The router begins to download the new file. Enter Ctrl-C or Break to stop the transfer before the Flash memory is erased. -------------------------------------------------------------------------------- Configuration Register The virtual configuration register is in nonvolatile RAM (NVRAM) and has the same functionality as other Cisco routers. You can view or modify the virtual configuration register from either the ROM monitor or the operating system software. Within ROM monitor, you can change the configuration register by entering the register value in hexadecimal format, or by allowing the ROM monitor to prompt you for the setting of each bit. Changing the Configuration Register Manually To change the virtual configuration register from the ROM monitor manually, enter the command confreg followed by the new value of the register in hexadecimal, as shown in the following example: rommon 1 > confreg 0x2101 You must reset or power cycle for new config to take effect rommon 2 > The value is always interpreted as hexadecimal. The new virtual configuration register value is written into NVRAM but does not take effect until you reset or reboot the router. Changing the Configuration Register Using Prompts Entering confreg without an argument displays the contents of the virtual configuration register and a prompt to alter the contents by describing the meaning of each bit. In either case, the new virtual configuration register value is written into NVRAM but does not take effect until you reset or reboot the router. The following display shows an example of entering the confreg command: rommon 7> confreg Configuration Summary enabled are: console baud: 9600 boot: the ROM Monitor do you wish to change the configuration? y/n [n]: y enable "diagnostic mode"? y/n [n]: y enable "use net in IP bcast address"? y/n [n]: enable "load rom after netboot fails"? y/n [n]: enable "use all zero broadcast"? y/n [n]: enable "break/abort has effect"? y/n [n]: enable "ignore system config info"? y/n [n]: change console baud rate? y/n [n]: y enter rate: 0 = 9600, 1 = 4800, 2 = 1200, 3 = 2400 [0]: 0 change the boot characteristics? y/n [n]: y enter to boot: 0 = ROM Monitor 1 = the boot helper image 2-15 = boot system [0]: 0 Configuration Summary enabled are: diagnostic mode console baud: 9600 boot: the ROM Monitor do you wish to change the configuration? y/n [n]: You must reset or power cycle for new config to take effect Console Download You can use console download, a ROM monitor function, to download over the router console port either a software image or a configuration file. After download, the file is either saved to the mini-Flash memory module or to main memory for execution (image files only). Use console download when you do not have access to a Trivial File Transfer Protocol (TFTP) server. -------------------------------------------------------------------------------- Note If you want to download a software image or a configuration file to the router over the console port, you must use the ROM monitor command. -------------------------------------------------------------------------------- -------------------------------------------------------------------------------- Note If you are using a PC to download a Cisco IOS image over the router console port at 115,200 bps, ensure that the PC serial port is using a 16550 universal asynchronous transmitter/receiver (UART). If the PC serial port is not using a 16550 UART, we recommend using a speed of 38,400 or less when downloading a Cisco IOS image over the console port. -------------------------------------------------------------------------------- Command Description The following are the syntax and descriptions for the xmodem console download command: xmodem [-cyrx] destination_file_name c Optional. Performs the download using 16-bit cyclic redundancy check (CRC-16) error checking to validate packets. Default is 8-bit CRC. y Optional. Sets the router to perform the download using Ymodem protocol. Default is Xmodem protocol. The protocols differ as follows: Xmodem supports a 128-block transfer size. Ymodem supports a 1024-block transfer size. Ymodem uses (CRC)-16 error checking to validate each packet. Depending on the device that the software is being downloaded from, this function might not be supported by Xmodem. r Optional. Image is loaded into DRAM for execution. Default is to load the image into Flash memory. x Optional. Image is loaded into DRAM without being executed. destination_file_name The name of the system image file or the system configuration file. In order for the router to recognize it, the name of the configuration file must be router_confg. Follow these steps to run Xmodem: -------------------------------------------------------------------------------- Step 1 Move the image file to the local drive where the Xmodem will execute. Step 2 Enter the xmodem command. -------------------------------------------------------------------------------- Error Reporting Because the ROM monitor console download uses the console to perform the data transfer, error messages are only displayed on the console when the data transfer is terminated. If an error does occur during a data transfer, the transfer is terminated, and an error message is displayed. If you have changed the baud rate from the default rate, the error message is followed by a message telling you to restore the terminal to the baud rate specified in the configuration register. Debug Commands Most ROM monitor debugging commands are functional only when Cisco IOS software has crashed or is halted. If you enter a debugging command and Cisco IOS crash information is not available, you see the following error message: "xxx: kernel context state is invalid, can not proceed." The following are ROM monitor debugging commands: stack or k—produces a stack trace; for example: rommon 6> stack Stack trace: PC = 0x801111b0 Frame 00: FP = 0x80005ea8 PC = 0x801111b0 Frame 01: FP = 0x80005eb4 PC = 0x80113694 Frame 02: FP = 0x80005f74 PC = 0x8010eb44 Frame 03: FP = 0x80005f9c PC = 0x80008118 Frame 04: FP = 0x80005fac PC = 0x80008064 Frame 05: FP = 0x80005fc4 PC = 0xfff03d70 context—displays processor context; for example: rommon 7> context CPU context of the most recent exception: PC = 0x801111b0 MSR = 0x00009032 CR = 0x53000035 LR = 0x80113694 CTR = 0x801065e4 XER = 0xa0006d36 DAR = 0xffffffff DSISR = 0xffffffff DEC = 0xffffffff TBU = 0xffffffff TBL = 0xffffffff IMMR = 0xffffffff R0 = 0x00000000 R1 = 0x80005ea8 R2 = 0xffffffff R3 = 0x00000000 R4 = 0x8fab0d76 R5 = 0x80657d00 R6 = 0x80570000 R7 = 0x80570000 R8 = 0x00000000 R9 = 0x80570000 R10 = 0x0000954c R11 = 0x00000000 R12 = 0x00000080 R13 = 0xffffffff R14 = 0xffffffff R15 = 0xffffffff R16 = 0xffffffff R17 = 0xffffffff R18 = 0xffffffff R19 = 0xffffffff R20 = 0xffffffff R21 = 0xffffffff R22 = 0xffffffff R23 = 0xffffffff R24 = 0xffffffff R25 = 0xffffffff R26 = 0xffffffff R27 = 0xffffffff R28 = 0xffffffff R29 = 0xffffffff R30 = 0xffffffff R31 = 0xffffffff frame—displays an individual stack frame. sysret—displays return information from the last booted system image. This information includes the reason for terminating the image, a stack dump of up to eight frames, and, if an exception is involved, the address where the exception occurred; for example: rommon 8> sysret System Return Info: count: 19, reason: user break pc:0x801111b0, error address: 0x801111b0 Stack Trace: FP: 0x80005ea8, PC: 0x801111b0 FP: 0x80005eb4, PC: 0x80113694 FP: 0x80005f74, PC: 0x8010eb44 FP: 0x80005f9c, PC: 0x80008118 FP: 0x80005fac, PC: 0x80008064 FP: 0x80005fc4, PC: 0xfff03d70 FP: 0x80005ffc, PC: 0x00000000 FP: 0x00000000, PC: 0x00000000 meminfo—displays size in bytes, starting address, available range of main memory, the starting point and size of packet memory, and size of NVRAM; for example: rommon 9> meminfo Main memory size: 40 MB. Available main memory starts at 0x10000, size 40896KB IO (packet) memory size: 5 percent of main memory. NVRAM size: 32KB Exiting the ROM Monitor You must set the configuration register to a value from 0x2 to 0xF for the router to boot a Cisco IOS image from Flash memory upon startup or reloading. The following example shows how to reset the configuration register and cause the router to boot a Cisco IOS image stored in Flash memory: rommon 1 > confreg 0x2101 You must reset or power cycle for new config to take effect rommon 2 >boot The router will boot the Cisco IOS image in Flash memory. The configuration register will change to 0x2101 the next time the router is reset or power cycled. © 1992-2005 Cisco Systems, Inc. All rights reserved.

  17. Hola otra vez. ¿Te he dicho de nada? Pues de nada Hay cosas que veo en la configuración que no están bien, los Dialer están mal (si solo tienes una interface ADSL deberías de tener solo 1 a no ser que te estén dando dos PVCS que no creo), no están definidas las listas de acceso para el Dialer0 y ademas tienes dos PVCS (el 8/32 y el 8/35), tambien tienes dos rutas por defecto con la misma métrica para cada uno de los Dialers, etc. Vamos a dejar de momento lo dela confioguración, me interesaría que te conectases por hiperterminal y enciendas el router, una vez que llegues a Router> capturame todo lo que te salga y pegamelo (me interesa ver que dicen los Dialer al intentar conectarse). ¿Sabes como se le borra la configuración a los Cisco? Dimelo y si no sabes te mando un documento donde lo explica. Seguimos hablando Salu2
  18. Hola atomed Para liberar esa entrada de la tabla ARP no te hace falta un script, con el propio comando ARP tienes opción de borrarla desde un simple acceso directo. Te paso un enlace donde te explica el uso de ARP y mira la opción -d que es la que te permite borrar esa entrada. Sería arp -d IPdelRouter http://www.microsoft.com/technet/prodte ... cec86.mspx Salu2
  19. En eso estamos de acuerdo, pero una cosa es explicarlo de una forma sencilla y otra muy distinta decir cosas que no son correctas. Salu2
  20. Ahora lo entiendo, La verdad es que no utilizo el escritorio remoto (uso PcAnywhere) y no sabía que el sonido te lo pasaba al cliente. La verdad es que eso esta bien, aunque en tu caso sea justo lo contrario de lo que tu quieres. Podrías probar el VNC para ver si con el te funciona (con PCAnywhere te suena en el que estas controlando no en el cliente), es lo único que se me ocurre. Salu2
  21. agamenon_dvc Si tiene todos los equipos juntos (de ahí venía la pregunta) no creo que necesite otro AP para nada, ademas dice que Internet le va bien. ¿De donde sacas tu eso? No conozco ningún switch que lleve un puerto para P2P (creo que ni yo ni nadie). Un puerto de Uplink es precisamente para conectar dos Switchs o Hubs entre si (para ponerlos en cascada) la diferencia con un puerto normal es que invierte la recepción con la transmisión para poder usar cables paralelos y no cruzados (al ser ambos dispositivos DTE o DCE tienen la transmisión y la recepción por el mismo par por lo que hay que cruzar los hilos). Actualmente la mayoría suelen traer puertos Autosense que hacen la conmutación automáticamente y ya no utilizan el puerto de Uplink. Mirate esto http://www.saulo.net/pub/redes/a.htm#2-4 Salu2
  22. Hola da2006 No entiendo muy bien lo que quieres hacer y porque no te sirve el control remoto (en principio es como si estuvieses sentado en el otro ordenador. Ya nos contarás algo mas Salu2
  23. Conectate por Telnet (igual que si lo hiciese por hiperterminal), entra en modo enable y saca la configuración (con sh run) y me la pegas para verla. Salu2
  24. agamenon_dvc a pesar de su trabalenguas algo se entiende, con lo que no estoy nada de acuerdo es con tus apreciaciones: Ya ha dicho bien claro que tiene una red inalambrica, por lo que lo que tendrá será un punto de acceso (o un router Wireless) es decir, será equivalente a un Hub ¿Porqué? Puedes mezclar perfectamente tarjetas de varias velocidades sin problema, para eso ya se sincronizaran el Hub-Switch con la tarjeta (y si no pueden se fuerza el puerto) Repito ¿porqué? ¿que diferencia hay entre ese puerto y los otros? En los antiguos además el último puerto solía ser el de Uplink, con lo que si conecta el PC a este con un cable paralelo no le va a funcionar. Ademas repito que es Wireless Repito que es Wireless GT4EVER1 No tienen porque interferirse entre ellos, el protocolo que utilizan las redes Ethernet (CSMA/CD) tiene previsto esto y solo permite que transmita un equipo, en el caso de que intenten transmitir dos a la vez se produciría una colisión y dejarían de transmitir todos los equipos. Mirate a que velocidad están conectados y que no tengas otras fuentes que puedan producir interferencias como teléfonos inslambricos, emisores de video Wireless, etc De todas formas no esperes que la transmisión de ficheros por Wireless sea tan rapida como por cable. Por cierto no nos dices cual es el problema exactamente, ni que router y que tarjetas tienes, Ya contarás Salu2
