comment How to set up default group permission in linux folder
It should work, the sticky-group sets the default group ownership for files created in the directory. This occurs at the filesystem level.

comment About the link layer of TCP/IP
You can use non-fragmenting packets of progressively decreasing size to try to learn something about the frame size of the networks you're traversing. Note that the MTU along the path will only decrease... never increase, so your knowledge will be very, very incomplete. The frame size is a hint as to the technology of the Link Layer. Another way as @coredump mentioned, for your first hop, you can use your MTU to give you a hint as to what you're on. (1500 Ethernet, 4464 Token Ring, 1492 PPPoE... )

comment Difficult to Delete Files in Linux
d'oh. Good spot. I never use unquoted variables in rm commands. I never noticed that find seems to be able to handle them fine. This actually works... weird... is it safe? touch important; touch "myfile -f important"; touch myfile; find "myfile -f important" -exec rm {} \;

comment Manual Firewall Configuration on Redhat IPTables
This looks like a good solution, it's scripting on top of Redhat's system, so nothing needs to be modified. rc.local is easy for novice admins to understand. A single script is really easy to backup, restore and port in the event the box needs to be rebuilt. An admin who understands Redhat, but doesn't know the firewall config won't be trapped by this either. Thank you :-)
