2009/11/13-30 [Computer/SW/Unix] UID:53523 Activity:nil | 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

2007/2/2-3 [Computer/Networking, Computer/SW/Unix] UID:45642 Activity:very high | 2/2 So is there some serious problem with gigabit? I keep seeing problems
with gigabit devices in 10/100 networks, or vice versa.
\_ do you think gigabit is some exotic, bleeding edge technology
just a few people are using?
\_ All I know is that when I use it in mixed networks, I keep
running into problems.

2006/12/22-26 [Computer/Networking] UID:45487 Activity:kinda low | 12/22 Does anyone know if there's a system call to test if a port is
availible without actually attempting to bind to it? Such a call
would be really useful for me.
\_ You could try to connect to it.
\_ You could also parse the output of "netstat -an" to see if
there's anything listening on the port. Are you sure this

2006/3/30-31 [Computer/SW/OS/OsX] UID:42561 Activity:nil | 3/30 Is there a way in Mac OS X to get the total packet count sent/received
for a particular network interface?
\_ $ netstat -I [interface] | tail -1
Col 5 (Ipkts) is the recv'd pkts, Col 7 (Opkts) is the sent pkts.
\_ Excellent! Thanks.
\_ Looks like Activity Monitor shows all network activity combined.

2006/1/4-6 [Computer/SW/Mail, Computer/SW/OS/Linux] UID:41223 Activity:nil | 1/4 Linux question: when I do a ypcat passwd on a Linux NIS client,
I see 11-13 lines, then a long pause and then it continues. On my
sun boxes and a few other Linux machines the whole map appears
instantly. Any ideas? netstat -i doesn't report any errors on the
client or nis server.

2005/10/7-9 [Computer/SW/OS/Solaris] UID:40017 Activity:nil | 10/7 I'm using winxp's rsh to connect to a solaris 2.8 machine. Is there
anyway to have the rsh connection timeout? Currently, it seems to
hang forever when something goes wrong. So far the only remedy is
to reboot the windoze machine. TIA.
\_ I don't know anything about winxp's rsh but generically speaking
you can wrap anything with perl or expect alarms/timers.

2005/5/12-15 [Computer/HW/Laptop, Computer/Networking] UID:37661 Activity:low | 5/12 Hi, I run windows Xp home edition on my laptop. It's hooked up
to my DSL router via ethernet most of the time. When I want to
just use the laptop without a net connection, the laptop sometimes
locks up and becomes really really slow. To the point where I can't
even right-click on the network icon to disable it temporarily.
I can't even do Ctrl-Alt-Delete to bring up the task manager.

but for IMAP. It wou use a current IMAP connection to allow
SMTP relaying from the same IP addres as that IMAP connection?

\_ Nope, That does not work. IMAP connections are persistent and

2004/6/12-14 [Computer/Networking] UID:30771 Activity:very high | 6/12 I setup imaps and pop3s on a freebsd virtual server. I can connect
to it if I first ssh into the machine and do pine. But if I try
to connect to it from somewhere outside (say soda) it always times
out. I can see that the daemons are running from "netstat -a".
What could be wrong? some router filtering on 993 or 995? Or
the server is configured in some weird way? this is a virtual server

2003/8/29-2004/2/14 [Computer/Networking] UID:12259 Activity:nil | 2/13 In NT or XP, is there a way to display the IP address of a remote
machine when the remote machine is pinging my machine? Thanks.
\_ netstat?
\- netstat is ridiculous for this. hammer. nail. bad. wrong.
i believe tcpdump runs on msftware:
