Since some days ago, I'm suffering a traumatic problem with Debian Wheezy.
Every time I boot the server, the only up interface is loopback. I have configured a static IP at /etc/network/interfaces
ifconfig -a shows properly the ethernet interface (eth2 in this case). When I do ifconfig eth2 up, it ups the interface as usual but without IP. I have to do ifconfig eth2 x.x.x.x to get an IP.
ifconfig after doing ifconfig eth2 up:
eth2 Link encap:Ethernet HWaddr 00:25:22:0d:dd:b1 inet6 addr: fe80::225:22ff:fe0d:ddb1/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:5 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:398 (398.0 B) Interrupt:42 Base address:0x2000 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:36 errors:0 dropped:0 overruns:0 frame:0 TX packets:36 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:17653 (17.2 KiB) TX bytes:17653 (17.2 KiB)
After that, I still have no acces to the internet. When I do a ping to Google, I get "ping: unknown host google.com"
Is not a problem from the router because I have other computers at this network working and I can acces to the computer with the problem through ssh too (after giving him an IP with ifconfig)
I tried a lot of things and a lot of people tried to help me, but I still have no idea to solve this issue.
I have to say that I think (and this is a personal opinion of a non-expert) the problem is at the start because the first problem is the lack of the interface up and it's IP.
Thanks for reading me and for your time.
This is the /etc/network/interfaces file:
