11/27   netstat -na reports that I have daemons listening
        on ports 515,
        111, and 1023.  How do I figure out what processes are listening
        where?
        \_ /etc/services can tell what services are _supposed_ to use
           those ports.  lsof can tell which processes are actually using
           what ports.
        \_ lsof -i:<portnum>
           Likely, 111 is portmap, 515 is lpd and 1023 is some rpc based
           service that binds to a semi-random port.
           \_ thanks
        \_ Just so you know, 90+% of attacks reported by portsentry on
           my firewall is for ports 53, 111, and 515.  Stupid redhat.
           FreeBSD rules.

11/12   How does one find out if a system has rootkit installed?
        \_ Unix or m$?
           \_ Unix. On M$ I always assume it's compromised.
              \_ Install Tripwire before you plug your server into The Net?
                 The only other answer I can think of is to reinstall the
                 OS from scratch on another server and do an md checksum

5/7     What's a good reverse port forwarding for a PC(inside firewall) ->
        Unix, so that I can VNC into the Unix that gets forwarded to
        PC's VNC server?

5/4     Is mail still down? I don't seem to be getting any and vermouth
        is unavailable. I saw a note saying it was down Sunday, but it's
        almost Tuesday now.
        \_ exim4 decided it wanted to just die. With the same config file and
        everything. Steven spent all weekend and a lot of yesterday migrating
        to a VM. A side effect is that NFS is now no longer on Keg, so crashy

4/22    ok, here's a little networking puzzler. I haven't been able to access
        youtube for a couple weeks. Couldn't figure out why. Happened on all
        browsers. traceroute did weird stuff and then timed out. Finally I
        got so frustrated I setup firefox to ssh tunnel through soda.csua,
        which worked great. Then, I kill the ssh proc, quit FF, and now,
        I can access youtube just fine from any browser. wtf? any

12/1    Just curious -- what do you guys generally use soda for? Why do you
        log on? Personally, I use it to keep a presence on IRC and AIM/gTalk
        at all times, and mess around with some Python programming (been
        setting up Twisted and such so I can play with making an irc bot).
