Re: [PLUG] favorite admin tools

1) mtr
ping/traceroute combo. Preinstalled on Redhat, though its in /usr/sbin,
so it is only in Root's path. MTR will run a traceroute, and keep
pinging each hop. This is an excellent way to keep an eye on a network
link or flaky connection
2) telnet {ip} {portnumber}
I couldn't begin to count the number of times I have had to telnet to port
80, 25, or 143 to troubleshoot an overbearing firewall, misconfigured
service, or norton/macafee security suite type app. Eventually you will
know the SMTP protocol well enough to send an email by manually echoing
the commands into telnet.
3) Not to rehash the vi/emacs war, but you really do need to at least know
a few commands in VI. You don't need to like it, but I've been on numerous
old boxes (BSDi, slowaris) where VI was the only editor installed, so it may
be your only option at some point. Besides.....what are you going to use
when your emacs config file gets corrupted? *ducks*
