[expert] usage shell script
Does anyone have a shell script example or a better idea on how to monitor network usage? I don't think I need anything as big as MRTG. I have a small network behind a Linux router (2 LAN cards) Can I pull this info with a shell script with ifconfig? and have it emailed daily? or monthly Really at the end of the day I would like a daily report, and a monthly report.

Hi Guys! If I run the ifdown eth0 then ifup eth0 it does not reset the RX and TX info on eth0? Any ideas how I can reset it?

Don't know but have you checked out ethereal?

Thanks if you don't need to know until tomorrow, you could try: echo `grep eth0 /proc/net/dev | cut -c8-18`-`sleep 86400 ; grep eth0 /proc/net/dev | cut -c8-18` | bc (for data in) and echo `grep eth0 /proc/net/dev | cut -c19-28`-`sleep 86400 ; grep eth0 /proc/net/dev | cut -c19-28` | bc (for data out) It'll give you a negative number, but the magnatude is correct. I'm sure there is a more elegant way, and when someone sees this hack, I'm sure they'll pipe up! -- Chuck Want to buy your Pack or Services from MandrakeSoft? Go to http://www.mandrakestore.com

Yeah, I went into it after i made the post and discovered that. Thanks for the clarification. A pretty cool program in of itself though. -Brandon _ Do You Yahoo!?

Re: [expert] usage on ports 980-989 and 1000-1024 and syslog --MARK

But I cannot for the life of me figure out what it's for, why it's being put there, or what is doing it. 2) I am noticing random ports between 980-989 and 1000-1024 being used as LISTENer ports. I cannot find any entries in /etc/services for these ports and don't know of a way to track down what process ID is using a specific port. This is also happening on all 3 boxes, so I think it's probably normal. Nonetheless, I'd like to know what is causing it. lsof -i, will identify whats useing what tcp ports. If anyone knows anything about either of these issues, I would really appreciate some help. Thanks in advance! -- MandrakeSoft http://www.mandrakesoft.com/ --Axalon

Nonetheless, I'd like to know what is causing it. lsof -i, will identify whats useing what tcp ports. lsof does not seem to be a standard package installed with Mandrake. But I went out and got it from rpmfind.net. Very nice package. I wish I'd known of it for the past several years. Oh well. Anyway, it showed me the following (minus the irrevelant stuff): Nope not in any of the default selections dureing install. but it's on the cd also. but rpmfind works just aswell. COMMAND PIDUSER FD TYPE DEVICE SIZE NODE NAME rpc.statd 386root3u inet540 UDP *:987 rpc.statd 386root4u inet543 TCP *:989 (LISTEN) rpc.rquot 396root3u inet563 UDP *:997 rpc.mount 406root3u inet583 UDP *:1006 rpc.mount 406root4u inet586 TCP *:1008 (LISTEN) rpc.mount 406root5u inet591 UDP *:1011 rpc.mount 406root6u inet594 TCP *:1013 (LISTEN) rpc.mount 406root8u inet599 UDP *:1016 rpc.mount 406root 10u inet602 TCP *:1018 (LISTEN) So, what is this stuff? Why is rpc.[mount,statd,rquot] listening on several different ports 1024? These are the nfs daemons (client or server escapes me at the moment it's late) /etc/rc.d/init.d/nfs stop /etc/rc.d/init.d/portmap stop ntsysv if you don't need them. they should also have man pages, ala, man rpc.statd -- MandrakeSoft http://www.mandrakesoft.com/ --Axalon
