I have setup one server for multiple ips. But when I bring eth0 down and then back up I get and error of: SIOCADDRT network is unreachable I am not exactly sure why I am getting this message everything seems to work fine. I can access anything from this server and I can access this server from anywhere. I have noticed some collisions and transmit errors. I am not sure what would be causing this. ifconfig returns eth0 Link encap:Ethernet HWaddr 01:10:26:19:12:B5 inet addr:<a href="http://10.1.4.2">10.1.4.2</a> Bcast:<a href="http://10.1.4.30">10.1.4.30</a> Mask:<a href="http://255.255.255.192">255.255.255.192</a> inet6 addr: fe80::214:22ff:fe17:15a9/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:248569 errors:0 dropped:0 overruns:0 frame:0 TX packets:71281 errors:66 dropped:0 overruns:0 carrier:66 collisions:180 txqueuelen:1000 RX bytes:80778446 (77.0 MiB) TX bytes:14645178 (13.9 MiB) Base address:0xecc0 Memory:fe6e0000-fe700000 eth0:0 Link encap:Ethernet HWaddr 01:10:26:19:12:B5 inet addr:<a href="http://10.1.4.1">10.1.4.1</a> Bcast:<a href="http://10.1.4.30">10.1.4.30</a> Mask:<a href="http://255.255.255.192">255.255.255.192</a> UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 Base address:0xecc0 Memory:fe6e0000-fe700000 lo Link encap:Local Loopback inet addr:<a href="http://127.0.0.1">127.0.0.1</a> Mask:<a href="http://255.0.0.0">255.0.0.0</a> inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:6762 errors:0 dropped:0 overruns:0 frame:0 TX packets:6762 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:274642 (268.2 KiB) TX bytes:274642 (268.2 KiB) route -n shows Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface <a href="http://10.1.4.0">10.1.4.0</a> <a href="http://0.0.0.0">0.0.0.0</a> <a href="http://255.255.255.192">255.255.255.192</a> U 0 0 0 eth0 <a href="http://169.254.0.0">169.254.0.0</a> <a href="http://0.0.0.0">0.0.0.0</a> <a href="http://255.255.0.0">255.255.0.0</a> U 0 0 0 eth0 <a href="http://0.0.0.0">0.0.0.0</a> <a href="http://10.1.4.35">10.1.4.35</a> <a href="http://0.0.0.0">0.0.0.0</a> UG 0 0 0 eth0 Thanks, -- Jonathan Carpenter Linux System Administrator Windows System Administrator <The Unix Geek>
