No problems here. I'm running from a kernel built from last night, and an installworld from yesterday morning. argus uses a 3c509, and wahoo uses a generic pci ethernet card. 50 foot coax, with termination, and a terminal server and x-terminal in between. This is an SMP kernel. Maybe you have a flakey radio shack coax [NEVER BUY COAX FROM RADIO SHACK!] or a flakey ethernet controller. First, I suggest going to a radio store [commercian or amatuer] and buy a good coax [or have one made], the connectors, the crimps, and the shielding will all be better. Also, watch the length of the coax. I don't at the moment recall the lengths to stay away from, but there are certain lengths that cause a high swr condition that will produce serious errors and possibly damage the tranceiver on the card. 8:20:21pm wahoo(3): ping argus PING argus (10.11.12.1): 56 data bytes 64 bytes from 10.11.12.1: icmp_seq=0 ttl=255 time=1.254 ms 64 bytes from 10.11.12.1: icmp_seq=1 ttl=255 time=1.168 ms 64 bytes from 10.11.12.1: icmp_seq=2 ttl=255 time=0.939 ms 64 bytes from 10.11.12.1: icmp_seq=3 ttl=255 time=0.942 ms 64 bytes from 10.11.12.1: icmp_seq=4 ttl=255 time=1.436 ms 64 bytes from 10.11.12.1: icmp_seq=5 ttl=255 time=0.939 ms 64 bytes from 10.11.12.1: icmp_seq=6 ttl=255 time=1.164 ms 64 bytes from 10.11.12.1: icmp_seq=7 ttl=255 time=1.539 ms 64 bytes from 10.11.12.1: icmp_seq=8 ttl=255 time=1.173 ms 64 bytes from 10.11.12.1: icmp_seq=9 ttl=255 time=1.314 ms 64 bytes from 10.11.12.1: icmp_seq=10 ttl=255 time=1.359 ms 64 bytes from 10.11.12.1: icmp_seq=11 ttl=255 time=1.547 ms 64 bytes from 10.11.12.1: icmp_seq=12 ttl=255 time=1.224 ms 64 bytes from 10.11.12.1: icmp_seq=13 ttl=255 time=1.186 ms 64 bytes from 10.11.12.1: icmp_seq=14 ttl=255 time=1.235 ms 64 bytes from 10.11.12.1: icmp_seq=15 ttl=255 time=1.545 ms 64 bytes from 10.11.12.1: icmp_seq=16 ttl=255 time=0.989 ms 64 bytes from 10.11.12.1: icmp_seq=17 ttl=255 time=1.644 ms 64 bytes from 10.11.12.1: icmp_seq=18 ttl=255 time=1.248 ms 64 bytes from 10.11.12.1: icmp_seq=19 ttl=255 time=1.621 ms 64 bytes from 10.11.12.1: icmp_seq=20 ttl=255 time=1.327 ms 64 bytes from 10.11.12.1: icmp_seq=21 ttl=255 time=1.176 ms 64 bytes from 10.11.12.1: icmp_seq=22 ttl=255 time=1.258 ms 64 bytes from 10.11.12.1: icmp_seq=23 ttl=255 time=1.259 ms 64 bytes from 10.11.12.1: icmp_seq=24 ttl=255 time=1.216 ms 64 bytes from 10.11.12.1: icmp_seq=25 ttl=255 time=1.207 ms 64 bytes from 10.11.12.1: icmp_seq=26 ttl=255 time=1.179 ms 64 bytes from 10.11.12.1: icmp_seq=27 ttl=255 time=1.049 ms 64 bytes from 10.11.12.1: icmp_seq=28 ttl=255 time=0.952 ms 64 bytes from 10.11.12.1: icmp_seq=29 ttl=255 time=1.390 ms ^C --- argus ping statistics --- 30 packets transmitted, 30 packets received, 0% packet loss round-trip min/avg/max/stddev = 0.939/1.249/1.644/0.196 ms In reply: > I am running 4.0-current SMP as of yesterday. > > Since the make world and rebuilding the kernel, the local network is > very strange. > > I changed the local network to be two machines, connected with a 10 > foot coax, properly terminated.
