Installation

Flash OpenWrt firmware

Attach your router and connect via webbrowser at http://192.168.1.1 with user “admin” and password “admin”. Go to SystemTools ‣ Firmware Upgrade and flash with OpenWrt firmware image downloaded from http://lightrouter.googlecode.com/files/openwrt-lightrouter-final-10-factory.bin

Basic Configuration

Password

After reboot set password login via telnet and set password to kuffner12568 (in Windows use Putty):

telnet 192.168.1.1

root@OpenWrt:/# passwd
Changing password for root
New password:
Retype password:
Password for root changed by root

Logout & Login via ssh root@192.168.1.1 (in Windows use Putty). Login via webbrowser at http://192.168.1.1 with user "root" and password "kuffner12568".

The number of cylinders for this disk is set to 5139.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
   (e.g., DOS FDISK, OS/2 FDISK)

SSH-Keys

Create SSH keys (leave passphrase empty):

ssh-keygen -t dsa

Generating public/private dsa key pair.
Enter file in which to save the key (/root/.ssh/id_dsa):
Created directory '/root/.ssh'.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /root/.ssh/id_dsa.
Your public key has been saved in /root/.ssh/id_dsa.pub.

Enable key authentification with datenscheibe.org:

scp /root/.ssh/id_dsa.pub light@datenscheibe.org:~/.ssh/atkuffner_id_dsa.pub
ssh light@datenscheibe.org "cat ~/.ssh/atkuffner_id_dsa.pub >> ~/.ssh/authorized_keys"

# set "option IdentityFile" to he file from which the identity (private key) for RSA or DSA authentication is read.  
# The default is ~/.ssh/identity for protocol version 1, and ~/.ssh/id_rsa and ~/.ssh/id_dsa for protocol version 2.
# ssh will also try to load certificate information from the filename obtained by appending -cert.pub to identity filenames.
