Hacking the Linksys WRT54G

Recently, my Dad purchased the Linksys WRT54G. If you follow tech news, you probably know that more or less, the device (as well as at least one other Linksys device) was hacked.

All that I have so far is a couple of links, here they are:

I-hacked article (good)

The last one looks the most promising.

I’ll be working on this over spring break (next week), so keep an eye out for a little ‘howto’ on this.

Don’t let your daemons die

Okay, let’s pretend that this isn’t the first time that I’ve posted in about a month. School really has been crazy. I haven’t really even had time to do anything new or cool lately. Tonight though, I’m putting school aside.

I’ve been having some problems with one of the daemons on one of my server’s randomly dying on me, and it got to the point that I couldn’t bear it anymore, I had to find a solution.

Thankfully, people have been using developing things for unix/linux for longer than I’ve been alive, and there’s a program that acts as a perfect band-aid. It’s called Monitor.

Get the file:
apt-get install monit

Create the monit control file:
(The monit control file uses a language of it’s own, if you want to learn it, feel free to go to the references at the bottom of this page. Otherwise just use some form of the file below)

check process sshd with pidfile /var/run/sshd.pid
start program "/etc/init.d/sshd start"
stop program "/etc/init.d/sshd stop"
if failed port 22 protocol ssh then restart
if 5 restarts within 5 cycles then timeout

Then, on the console type monit -c [path to the above file] -d [number of seconds inbetween checks]

This this is saving me a lot of trouble.



Hopefully it wont be another month,
