You can use multiple windows in screen. All commands start with CTRL-A, then another key for the command itself. If you really want to send a CTRL-A to your application (Like to go to the beginning of the current line in bash for example, hit CTRL-A twice.) CTRL-A CTRL-D Detach your current session “screen -rd” to get back to it CTRL-A CTRL-C create another “window” CTRL-A CTRL-N next window CTRL-A CTRL-P previous window CTRL-A ” see list of current windows CTRL-A [ Copy mode… you can see the scrollback buffer with this. Esc to exit CTRL-A ? Help for further stuff. CTRL-A 1 jump to first screen CTRL-A 2 (2nd screen etc) Great tips. You can use multiple windows in screen.

Netcat is completely new to me and very cool. My favorite linux tricks are rather simple: - use of rlwrap to add command line history to sqlplus (learned this from Lutz Hartmann) - liberal use of aliases to make everything easier - tailalert, vialert, cdbdump, vitns, etc, etc Excellent tips!

Although I am afraid to use python to publish directories. That's why I have putty... Of course being unix/linux you can pipe it to a grep -v "timed out" and then > to a log file and filter out the closed ports leaving only interesting ports. I already did a partial scan of my Debian linux box. I just need to figure out a reasonable max value for the range. I also like this because it lists the default ports for things I did not know had default ports. 17 (qotd): Connection timed out -- quote of the day?!?!?!? Thanks! Great tips!!!

One other very convenient thing of ethtool (and where I used to use mii-tool for) is inspecting network interfaces for connectivity. Besides that: ethtool also shows speed and duplex setting, which can influence performance (severely, if NFS is used ;-) Forgive me for playing wiseguy, but disk usage by folder can be done more easy the following way:

du -sm /home/* | sort -r

John. Tyler,

I love the blinking lights tip, I’ve certainly been in that situation before and it’s a great way to know which cable not to pull out ;)

The other command that I love for digging down and finding out which programs are listening on which ports is the ‘lsof’ command, it’s a very useful one if you either don’t know which ports a particular program listens on, or (vice-versa) want to know which program is the one listening on a particular port.
