OpenWRT by default installs telnet on the Linksys. To access it you need a telnet client, which is installed on most Operating Systems by default. Connect your computer to one of the LAN-Ports on the back of the Linksys. To open a telnet-connection:

After restarting the router you can login via ssh.  

After restarting the router you can login via ssh.  

* on linux: ssh 192.168.1.1

* MacOSX: open a console, and type ssh 192.168.1.1

* MacOSX: open a console, and type "ssh -l root 192.168.1.1"

* On Windows you will need a seperate ssh-client, [http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html putty] is a good one. Type 192.168.1.1 into the address field, select ssh as protocol and press connect.

In terms of hardware, the linksys (v2) has only two interfaces called eth0 and eth1. The eth0 interface is split up via so called vlan tagging which results in two additional interfaces seen by the network stack vlan0 and vlan1 so you end up  having three configurable interfaces which serve different purposes.

->'''nvram show | grep lan_ifnames''' will show all devices currently in the bridge, removing eth1 will do the trick e.g. ->'''nvram set lan_ifnames="eth0 vlan0"'''
