System: NetBSD rainier.reedmedia.net 2.0.2 NetBSD 2.0.2 (GENERIC) #0: Wed Mar 23 08:53:42 UTC 2005 email@example.com:/home/builds/ab/netbsd-2-0-2-RELEASE/i386/200503220140Z-obj/home/builds/ab/netbsd-2-0-2-RELEASE/src/sys/arch/i386/compile/GENERIC i386
Started trafshow using libpcap-0.9.3nb3. When I exited my networking was
dead. When I restart trafshow my networking works again.
Or when I start tcpdump, my networking works again.
If I use "sudo trafshow -p" my networking does not come back up.
My network card:
tlp0 at pci0 dev 9 function 0: Lite-On 82C169 Ethernet, pass 2.0
tlp0: interrupting at irq 5
tlp0: Ethernet address 00:a0:cc:24:2d:40
ukphy0 at tlp0 phy 1: Generic IEEE 802.3u media interface
ukphy0: MTD972 10/100 media interface (OUI 0x00032d, model 0x0000), rev. 8
ukphy0: 10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, auto
Taking interface down, delete and back "up" and also assign an IP
does not work to make my networking come alive again.
A "reboot" works to make the card work again.
When trafshow or tcpdump is running (and my networking is working):
and my networking works.
When trafshow (or tcpdump) is stopped (and my networking is down):
tlp0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
tcpdump says I have traffic out but nothing in. tcpdump on another
machine shows traffic going both ways even when network appears to
netstat -ain output shows no change whether I am running tcpdump

(Greg Troxel gave me some more ideas for troubleshooting, but I
didn't try all yet.)
I recall I had same problem with same nic on another hardware
a few months ago.
Start and exit tcpdump or trafshow.
