When I was monitoring a university network, sometimes I find departments deploying rogue/unauthorized wifi access points and more often than not the tool that I use is nmap. Enterprise Networking Planet's Ms. carla Schroder writes more about nmap and other nifty tools for Linux administrators.
I have been using X over SSH for quite awhile now since I was running IE over WINE on a remote Linux server but for file editing of remote resources over SSH, I find Ms. Schroder's tip very useful.
We all have our favorite methods of using SSH for secure remote access. SSH is slick, quick, and operates well over slow links. The one downside is you have to transfer files to your local PC to edit them, then transfer them back. This isn't too bad, but there is an alternative for folks who want an easier way. With sshfs you can mount any remote filesystem to your local PC, and access it just like any local filesystem. This magic happens thanks to FUSE- Filesystem In Userspace.
Try it out. It might work for you. As for me, I will see if I can get FUSE to work on my Mac. :)
BTW, if you have some Linux admin tips and tricks, please do not hesitate to send it over.
