SO, is there a way to view the contents of an archived.cfg file without overwriting the active (working) config? Message Edited by buckyswider on 06:13 PM. Cracking Linksys “Encryption”. Perusing the release notes for the latest Linksys WRT120N firmware, one of the more interesting comments reads: Firmware 1.0.07 (Build 01) – Encrypts the configuration file. Having previously reversed their firmware obfuscation and patched their code to re-enable JTAG debugging. Linksys Getting Started with the Router Configuration Follow the instructions to configure your router. Be sure your computer is connected to a LAN port on the router and set to receive an automatic IP address from the DHCP server. Open a Web browser and type 192.168.1.1 in the address bar.

This How-To Tutorial maybe helpful when you have a configuration that needs to be copied from a file, or from one Cisco router to another. This procedure is described in the Microsoft Hyperterminal Terminal Emulation Software.You may wish to install a text file configuration into a Cisco router by performing these steps.Note: If the configuration is already uploaded, go directly to step 8.

1.If the configuration needs to be copied from another router, connect to that router through the console or Telnet.At the Router > prompt, issue the enable command and provide the required password. The prompt changes to Router#, indicating that the router is now in privileged mode.
2.To force the router to return the entire response at once, rather than a screen at a time, issue the terminal length0 command.This allows you to capture the configuration without extraneous --more-- prompts generated when the router responds a screen at a time.
3.On the HyperTerminal menu, select Transfer > Capture Text. The Capture Text window appears
4.Name this file config.txt
5.To dismiss the Capture Text window and begin the capture, click Start.
6.Issue the show running-config command and allow time for the router to complete its response.
7.To end the screen capture, select Transfer > Capture Text > Stop on the HyperTerminal menu.
8.Open the config.txt file you created in any text editor, such as Notepad or Wordpad.
9.Search for and remove any line that starts with AAA.Note: This step removes any security commands that could lock you out of the router.
10.For each interface that is followed by shutdown, leave it as it is.
11.For all other interfaces, issue the noshutdown command, as shown in this example:
!interface Serial0/0no ip addressno ip directed-broadcastno shutdown!
12.Save the file.
13.Connect to the router that needs the configuration.
14.Open the config.txt file.
15.Highlight the entire contents of the config.txt file.To accomplish this, drag the cursor from before the first character to after the last character in the file while holding down the left mouse button. If you are using Notepad, select Edit > Select All from the menu.
16.Copy the selected text to the Windows clipboard.To copy, you can either select Edit > Copy from the text editor's menu, or hold down the CTRL key and simultaneously press the C key.
17.Switch to the HyperTerminal window and issue the configure terminal command at the Router# prompt and select Enter.
18.Paste the configuration file into the router by selecting Edit > Paste to Host on the HyperTerminal menu.
19.After the configuration has finished pasting, and the router brings you back to the configuration prompt, issue the copy running-config startup-config command. This writes the configuration into memory.
20.To return to the Router# prompt, issue the exit command.

Read Linksys Config Files

I use the tomato firmware for my router and I'm sick of the web interface. Does anyone know what files correspond to different configurations? The router I use is the Linksys WRT54GL.

Example:
the firewall is edited in /etc/iptables

On Saturday night, the edits were far less noticeable. Film naruto shippuden episode 91 english dubbed download. The show was cancelled on the channel after the 97th episode. Before moving to Saturdays at 11:00 p.m. When the dubbed episodes aired on Wednesdays, they were edited and censored for blood, language, and anything suggestive: however, when the time slot had changed to 11:00 p.m.

Questions:

  • Where is the wireless key kept?
  • Where is the static DHCP kept? ('static dhcp' maps MAC addresses to IP addresses)

The Tomato firmware seems to be aimed mostly at use via the GUI, from a quick read over their FAQ. It is possible to do perform configuration tasks from the command line, but the documentation is somewhat sparse. It looks like command line access is there more for diagnostic purposes. Maybe it's time to give the more bare-bones OpenWRT a go? (I recently moved from OpenWRT to Tomato for my home networks, just to stop myself from tinkering)

That said, the 'nvram show' and 'nvram set var='blah'' commands are going to get you a long way with command line configuration - nvram is certainly where most configuration is kept. /etc/dnsmasq.conf seems to hold the static DHCP entries on my system.
