Johann's Research

I'm not sure if my stuff is really research, but this is some of the stuff that I'm busy with:

Meraka wireless Network

We are making use of Linksys WRT54 wifi routers, re-flashed with dd-wrt software. We've also enabled WPA corporate mode, using a Radius server that verify users against the CSIR LDAP server.

Upgrading the dd-wrt firmware on a linksys.

Firmware upgrades are usually done via the WEB gui. Here is the instructions to do it on the command line. It's important to know how to do it, so that we can script it in future. Fist enable ssh via the WEB gui. You can find it under Administrator -> Services -> Secure Shell. Select SSHd en then add your ssh public key under the Authorized Keys section. Save settings. Now you can login without a password as well run remotes commands via ssh.

scp ftp/linksys/dd-wrt/dd-wrt.v24_std_generic.bin root@192.168.1.1:/tmp
ssh root@192.168.1.1 "write /tmp/dd-wrt.v24_std_generic.bin linux"
ssh root@192.168.1.1 reboot

Load WEB gui and verify if upgrade worked. Yes - all new.
