===Connect to the Linksys via telnet===
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:
*on Windows: -->Startmenu-->Ausführen--> telnet 192.168.1.1
*on MacOSX: ??
*on Linux: telnet 192.168.1.1
There is no login/pass on telnet. You can now start to configure the linksys to your demands. To close the connection do "CTRL-D"
===Networkconfiguration===
Before you can install new software on the linksys, you will need to connect it to the internet. For this howto we will assume that you have access to the internet via a LAN.
Connect the WAN-interface of the Linksys with a cable to the network. To configure the WAN-interface of the router, issue the following commands:
'''nvram get wan_ifname''' (this will print the name of the WAN interface)
'''ifconfig <name-of-WAN-interface> xxx.xxx.xxx.xxx''' (put in an ip used on the LAN)
'''route add default gw xxx.xxx.xxx.xxx''' (put in the ip of the gateway)
'''echo 141.54.1.1 >> /etc/resolv.conf''' (this configures the nameservers)
'''ping subsignal.org''' (to test if it works, abort with CTRL-C)
===Install ssh (dropbear)===
===Install ssh (dropbear)===
Telnet is by design very insecure, a far better way of configuring the router is ssh. there is a ssh-server for OpenWRT available, its name is dropbear. you can use the "ipkg" tool to install it. login to the linksys using telnet and issue the following commands:
'''ipkg update''' (this will get a list of available software from the internet)
'''ipkg install dropbear''' (installs the dropbear-package)
To set the root-password:
'''passwd'''
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
* 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.
Login with username: root and pass: whatever you chose as root-password. If this works, you can now safely stop the insecure telnet service:
'''rm /etc/init.d/S41Telnet'''
