When I alias a new IP onto an em device running on a 4-STABLE server (I'm in the process of moving to 6.x, haven't gotten to this server yet), for some reason, it isn't seeing appropriate 'arp' messages, so the upstream switches and such aren't getting the information .... All the local server can ping the IP, but, for instance, the Cisco 2950 that all the servers are plugged into can't: #ping 200.46.208.96 Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 200.46.208.96, timeout is 2 seconds: ..... Success rate is 0 percent (0/5) but, the another IP on the server does ping: #ping 200.46.204.172 Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 200.46.204.172, timeout is 2 seconds: !!!!! Success rate is 100 percent (5/5), round-trip min/avg/max = 1/2/4 ms I've tried 'arp -s' on the server where the IP *was* running on, but that isn't working, altho ping'ng from any of the servers does work: # ping 200.46.208.96 PING 200.46.208.96 (200.46.208.96): 56 data bytes 64 bytes from 200.46.208.96: icmp_seq=0 ttl=64 time=0.507 ms 64 bytes from 200.46.208.96: icmp_seq=1 ttl=64 time=0.217 ms 64 bytes from 200.46.208.96: icmp_seq=2 ttl=64 time=0.229 ms ^C --- 200.46.208.96 ping statistics --- 3 packets transmitted, 3 packets received, 0% packet loss round-trip min/avg/max/stddev = 0.217/0.318/0.507/0.134 ms Is there something else that I can do on the FreeBSD side to get this to work? :( Some way of forcing the appropriate arp packets to be sent out ... ? ---- Marc G.
