I can't figure this one out. There's a Belken USB->Ethernet adapter as eth2 on my server. After a reboot it doesn't communicate with anything ever though it's up:
ipaddress is 68.15.6.136 gateway is 68.15.6.129
# ifconfig eth2 eth2 Link encap:Ethernet HWaddr 00:05:1B:00:52:BF inet addr:68.15.6.136 Bcast:68.15.6.191 Mask:255.255.255.192 inet6 addr: fe80::205:1bff:fe00:52bf/64 Scope:Link UP BROADCAST MULTICAST MTU:1536 Metric:1 RX packets:208 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:13540 (13.2 KiB) TX bytes:0 (0.0 b)
it can ping itself:
# ping 68.15.6.136 PING 68.15.6.136 (68.15.6.136) 56(84) bytes of data. 64 bytes from 68.15.6.136: icmp_seq=0 ttl=64 time=0.056 ms 64 bytes from 68.15.6.136: icmp_seq=1 ttl=64 time=0.021 ms
--- 68.15.6.136 ping statistics --- 2 packets transmitted, 2 received, 0% packet loss, time 999ms rtt min/avg/max/mdev = 0.021/0.038/0.056/0.018 ms, pipe 2
can't ping the gateway:
# ping 68.15.6.129 PING 68.15.6.129 (68.15.6.129) 56(84) bytes of data. From 68.15.6.136 icmp_seq=0 Destination Host Unreachable
bounce the interface:
# ifconfig eth2 down # ifconfig eth2 up
now it works:
# ping 68.15.6.129 PING 68.15.6.129 (68.15.6.129) 56(84) bytes of data. 64 bytes from 68.15.6.129: icmp_seq=0 ttl=64 time=64.4 ms 64 bytes from 68.15.6.129: icmp_seq=1 ttl=64 time=12.3 ms 64 bytes from 68.15.6.129: icmp_seq=2 ttl=64 time=12.3 ms
Any ideas?
