Hello questions,
I've there got a REALLY strange problem with one of my servers:
rl0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
inet XXX.YY.62.126 netmask 0xfffffff8 broadcast 195.49.62.127
inet6 fe80::200:e8ff:feec:aaa8%rl0 prefixlen 64 scopeid 0x1
inet XXX.YY.33.19 netmask 0xffffff80 broadcast 195.49.33.127
inet XXX.YY.62.125 netmask 0xfffffff8 broadcast 195.49.62.127
inet XXX.YY.33.29 netmask 0xffffff80 broadcast 195.49.33.127
ether 00:00:e8:ec:aa:a8

gif2: flags=8010<POINTOPOINT,MULTICAST> mtu 1280
gif3: flags=8010<POINTOPOINT,MULTICAST> mtu 1280
lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 16384
inet6 ::1 prefixlen 128
inet6 fe80::1%lo0 prefixlen 64 scopeid 0x8

ppp0: flags=8010<POINTOPOINT,MULTICAST> mtu 1500
sl0: flags=c010<POINTOPOINT,LINK2,MULTICAST> mtu 552
Now from localhost, I can ping .126 and .19 but not .125 or .29:
root@gamma 18:20:40 ~/scripts # ping XXX.YY.62.126
PING 1XXX.YY.62.126 (XXX.YY.62.126): 56 data bytes
64 bytes from XXX.YY.62.126: icmp_seq=0 ttl=64 time=0.089 ms
64 bytes from XXX.YY.62.126: icmp_seq=1 ttl=64 time=0.055 ms
root@gamma 18:23:01 ~/scripts # ping XXX.YY.33.29
PING XXX.YY.62.125 (XXX.YY.33.29): 56 data bytes
ping: sendto: Host is down
ping: sendto: Host is down
(the same goes for the other two IPs).
Now a host on the same switch is able to ping all FOUR IPs:
root@alpha 18:25:01 ~ $ ping XXX.YY.33.29
PING XXX.YY.33.29 (XXX.YY.33.29): 56 data bytes
64 bytes from XXX.YY.33.29: icmp_seq=0 ttl=64 time=0.358 ms
64 bytes from XXX.YY.33.29: icmp_seq=1 ttl=64 time=0.178 ms
64 bytes from XXX.YY.33.29: icmp_seq=2 ttl=64 time=0.171 ms
This machine is running on FreeBSD 4.3-STABLE FreeBSD 4.3-STABLE

WTF is going on here??
Best regards,
Gabriel
