#2While how-to lists hardly see the light of day (the front page) on HN, I had hate to see one like this go unrecognized.

#3A pretty unique collection, worth a look!

Agreed; way better than the usual lists.

#5Quick question, is it just me or is gig ethernet 1000 Mbps, not 1024?
Man "mebibits" sounds terrible.

#6Trick 5 (opening a remote port on a "public" machine to connect back to your local machine) is great. Combine it:
office$ ssh -R 9999:localhost:22 user@home ## do this in a screen for good measure
and another lesser known ssh feature:
home$ ssh -D 8888 -p 9999 user@localhost
and now you have a SOCKS proxy on home:8888 that will access everything visible to the computer named "office".
For extra credit add PingTunnel and a hotspot that happens to allow ICMP and enjoy free internet wherever you go.

#7Very nice collection. A tech at the datacenter that hosts one my servers showed me trick #3 and I remember being thrilled sitting there watching him do stuff on my server and sharing the keyboard to type messages back and forth in vi.
My company uses trick #5 as a primary feature for accessing the remote Linux machines that our product is built upon. We have it set up so that every single machine automatically creates a reverse SSH tunnel to the server on boot, so that the tunnel is always accessible in case we need it. Very cool stuff.

#8If you thought #8 was really cool and useful, you should go learn bash, sed, and awk. Stuff like #8 is what makes unix fun.

#9When I was doing AIX administration, I liked that one command to kill processes with open files keeping a mountpoint mounted was:
fuser -fuck /dev/whatever
Oh, admin humor.

Thanks for the tip on ping tunnel, I hadn't heard of it.... Going to have fun checking it out
