cable modem activity
I left the computer on and went for lunch. The computer wasn't doing anything that used the modem and I had no scheduled jobs. When I came back from lunch the cable model was going at full blast. Is there a command or something I can do to see what processes are running instead of just shutting down the computer? ===== The true measure of a man is how he treats someone who can do him absolutely no good. -Samuel Johnson, lexicographer (1709-1784)
"netstat -rn" will show the active connections. If you want more detail, you could tcpdump your traffic: [root@sergeant root]# tcpdump -i eth0 port not 22 tcpdump: listening on eth0 14:19:58.194044 216.34.209.9.https > h24-76-10-54.wp.shawcable.net.3649: P 3039920030:3039920403(373) ack 1192984335 win 7504 <nop,nop,timestamp 1814579476 325844576> (DF) 14:19:58.194951 216.34.209.9.https > h24-76-10-54.wp.shawcable.net.3649: P 373:410(37) ack 1 win 7504 <nop,nop,timestamp 1814579476 325844576> (DF) 14:19:58.210340 h24-76-10-54.wp.shawcable.net.4990 > ns3nr.wp.shawcable.net.domain: 46310+ PTR? 54.10.76.24.in-addr.arpa. (42) (DF) Of course you have to be able to decode the above ;) Sean On Wed, 21 Apr 2004, Mel Seder wrote:

Slackware has "netwatch" which is basically a "top" for network connections. I haven't used it much but it potentially really useful. Home page here: http://www.slctech.org/~mackay/netwatch.html Not sure if it ships with other distributions. (does not come with Mandrake) Also, proftpd now has a "ftptop" which does that for FTP connections. Regards, -- John Lange BigHostBox.com (204) 885 0872 On Wed, 2004-04-21 at 14:11, Mel Seder wrote:

I use something called "iftop"... http://www.ex-parrot.com/~pdw/iftop/ If you dig around, you'll likely find an rpm version of it. I found one that was a bit out of date, but it was easy to update the .spec file to build a binary rpm from the latest source tarball. -- Gilbert E.
