I purchased a new laptop recently, and I'm working on hardening it. Specifically, I'm interested in increasing my chances of recovering the machine in the event that it's ever stolen. The system runs Ubuntu 11.04 (Natty).
I've installed Prey on the machine, of course. I've also created a guest account that requires no password to log in, to give a would-be thief an opportunity to log into the machine so I can track him with Prey. (I've got some other pretty rad countermeasures on there too.) The last thing I want to get on there is a solid keylogger.
Does anyone have any keylogger experience? I've Googled around and know that there are options, but I was hoping to benefit from the community's expertise on the issue. Some options seem to have disappeared from the Canonical repositories recently (I was looking at lkl in particular), and I'm not clear what the current leaders are.
Do you have any recommendations as to which is the current "premier" Ubuntu Keylogger?
For what it's worth, this whole venture was inspired by the fantastic "Pwned by the Owner" talk from Defcon 18. It definitely warrants a watch if you've never seen it before.
