Hello! I'm a bit of a newbie to FreeBSD so please bare with me if what I ask is a simple question. I have a small LAN at my home consisting of a Windoze 98 and a FreeBSD 3.3-RELEASE. The problem is when I FTP a file from my FreeBSD box to my Windoze 98 box: I get an incredible amount of collisions. I can tell by doing a netstat -i and by just looking at my collision light on my hub. I've read the FreeBSD mailinglist archives and most people suggest that this is a hardware problem. However I don't think this is the case with me because my FreeBSD box was a NT4 box previously. When I would transfer files from my NT4 box to my Windoze 98 box, I had the same problem: lots of collisions. However, in NT I changed the NIC to half duplex from full and that cleared up the problem. However, I can't seem to set it to half duplex with ifconfig -media 10baseT/UTP. I think partly because they are only 10baseT cards, not 100baseT. I also read in the mailinglist archives to try TCP_EXTENSIONS="YES" in my rc.conf file, but that didn't do the trick either. I'm wondering if anyone has had a problem like this? And more importantly, solved it! Here are some of the particulars: - FreeBSD box has 2 NICs, both are PCI. - One is a D-LINK528CT (NE2000 compatible) which is my Internet connection (ed1). - The other is my LAN connect, a RealTek 8029 (also NE2000 compatible; ed2). - Both NICs are 10baseT. sunnie$ uname -a FreeBSD sunnie 3.3-RELEASE FreeBSD 3.3-RELEASE #4: Wed Mar 1 22:08:28 EST 2000 cappy@sunnie:/usr/src/sys/compile/SUNNIE i386 sunnie$ ifconfig -a ed1: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500 inet 24.xxx.xxx.xx netmask 0xffffffe0 broadcast 24.xxx.xxx.xx ether 00:80:c8:f3:0b:25 ed2: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500 inet 192.168.0.1 netmask 0xffffff00 broadcast 192.168.0.255 ether 00:c0:a8:50:9e:a7 lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 16384 inet 127.0.0.1 netmask 0xff000000 This is a netstat done before I FTP a 15 meg file from my FreeBSD to my Windoze 98 box: sunnie$ netstat -i Name Mtu Network Address Ipkts Ierrs Opkts Oerrs Coll ed1 1500 <Link> 00.80.c8.f3.0b.25 25945 0 19650 0 1 ed1 1500 24.xxx.xxx.xx cr1xxxxx-a.etob 25945 0 19650 0 1 ed2 1500 <Link> 00.c0.a8.50.9e.a7 69658 0 45790 0 1 ed2 1500 192.168 192.168.0.1 69658 0 45790 0 1 lo0 16384 <Link> 46 0 46 0 0 lo0 16384 127 localhost 46 0 46 0 0 This is after: sunnie$ netstat -i Name Mtu Network Address Ipkts Ierrs Opkts Oerrs Coll ed1 1500 <Link> 00.80.c8.f3.0b.25 26031 0 19710 0 1 ed1 1500 24.xxx.xxx.xx cr1xxxxx-a.etob 26031 0 19710 0 1 ed2 1500 <Link> 00.c0.a8.50.9e.a7 75658 0 59308 0 1014 ed2 1500 192.168 192.168.0.1 75658 0 59308 0 1014 lo0 16384 <Link> 46 0 46 0 0 lo0 16384 127 localhost 46 0 46 0 0 Any help would be appreciated.
