Please read the following and then, when we both have the same information, I'm going to try again to assist you. HINT TO READERS: I hope someone else will help us both because I have obligations that I'm stealing time from that I can ill afford. There is a LARTC mailing list thread dated (about) 24 thru 26 June 2003 between Trevor Warren and Michael Ulitskiy whose Subject is "u32 clarification...limits on 2000>???" Please use your favorite method to find it. Note that there may be kernel issues not mentioned by them; kernels change. I'd like to suggest that you see if anyone involved in that thread will send you a testing script; perhaps you could find a way to start with a working setup and then apply minor changes until either it breaks or it suits you. ___ LARTC mailing list / [EMAIL PROTECTED] http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/

I have done as you suggested (actually, if you noticed in the Action subroutine, all the error reporting from before was still there I just commented it out) and this is what I've come up with. This is the last known good command and then the command that errors, as well as the error message, and the counter I added back in. Performing: /sbin/tc filter add dev eth1 protocol ip parent 1: u32 ht 2:54: match ip dst 216.19.20.84 flowid 1:FFFB 2045 Performing: /sbin/tc filter add dev eth1 protocol ip parent 1: u32 ht 2:2E: match ip dst 216.19.46.46 flowid 1:FFFB WHOOPS: RTNETLINK answers: File exists The error exists on the 2046th command. Any tc filter command I try to add from here on out gives me the same error even if I try it manually instead of using the script. I examined the previous commands that worked fine and there are plenty that dump into the 2:2E: table. > I think the line above should count down from 65535, not up. As you can see, I did this as you suggested. I like it better because it keeps things very separate so there's no confusion. Thanks for the suggestion. > Sorry, that's all I have time for now. Any time you can spare is incredibly helpful. Thank you. Adam Towarnyckyj ___ LARTC mailing list / [EMAIL PROTECTED] http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/

This took me a little while to figure out myself, so I thought I'd post it. If you are running a bash script, what you want to do is to add at the top: set -e # causes script exit on error set -x # causes command to be printed before it is executed Glen -- ** Glen W.

Is there some way wherein I > can force my 1000T card to be eth0. You can also create an alias for the device driver. I'm not that well-versed in the various distribution and kernel version differences, but this is how I do it. If running a 2.4 kernel, edit /etc/modules.conf (or if running Debian, edit /etc/modutils/alias, and afterward run update-modules) and add alias eth0 where is the name of the device driver module for your gigabit card, say, e1000. If running 2.6, add the same line to /etc/modprobe.d/aliases . A reboot afterward may do the trick if you don't have an update-modules command that will get the right aliases going. Hope that helps. -- ** Glen W.

RE: [LARTC] Problem with multiple N/W cards
Yup. I had the same problem. Soltuion: use nameif You can call any interface anything you want. Turning off auto negotiation and flow control may be an option when you load the moadule (check docs)-- example: if it is a 3com 100mbps 905b - you may be able to use ethtool to change it. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of anupam chomal Sent: Thursday, July 15, 2004 3:51 AM To: [EMAIL PROTECTED] Subject: [LARTC] Problem with multiple N/W cards Hi, I am trying to set up a linux box with 5 N/W cards of which one is 10/100/1000T and the others are 10/100T.
