Wow, what a fast response. But I can't configure the switch (DLink DES-1024R+), everything is autonegotiated. Actually I have seen this in a previous thread, but since there is no way to configure the switch this is no solution. Is this OS dependant ? The rest of the servers (NT unfortunately) don't experience this. Is there a way to verify this ? Modify this in Linux ? John Birkhead wrote:
Hi, Being a SuSE newbie I don't know from the O/S perspective what the problem may be - however, check the duplex setting on the switch - it should match (either full or half) the setting from the card. This is supposed to be auto-negotiated but depending upon the mix of NIC and hub/switch this sometimes goes wrong...

Hi all, A while ago (a few weeks) I installed a sambaserver on a Suse 8.1 box. I thought it was ready for "production" but I found a problem. I managed to get winbind autenticate the users, but the response of making a networkconnection with Win-clients is rather slow. Today I tried to copy a file of 162Mb on it and this took about tree quarters of an hour. Any suggestions to diagnose this problem ? B.T.W. the switch (=hub-like device) indicates the NIC runs at 100Mb. TIA

Just for the fun of it, I downloaded the same file, and this took less than two minutes. I uploaded it again, and WinME indictated more than 45 minutes, and the lights of the switch blinked slowly, like the first time I uploaded the file. Is this any clue ? Koenraad Lelong wrote:

Linux drivers seem to be well behaved when it comes to autonegotiation, unlike Windows drivers. To check and see what speed is being negotiated, check your boot logs on the Linux machine. When the nic comes up you will see the speed (10/100) and mode (half or full duplex) that was negotiated with the switch. You can also cat /proc/net/dev and look for any errors. If you see errs or colls you may want to try a different nic - preferably a different brand. Tulip based adapters have been popular, on the higher end I like the Intel PRO-100+ and it's kin. -- John LeMay KC2KTH Senior Enterprise Consultant NJMC | http://www.njmc.com | Phone 732-557-4848 Specializing in Microsoft and Unix based solutions
