I've a server on Centos 6.5 and after a yum -y update we've lost all connectivity on it, the only access we have is on shell thru SolusVM serial console, I've tried everything (SFTP, SCP) on my reach to reestablish the network but doesn't seem to run, and we can't get out our backups to reinstall everything.

Anyone has an idea that could work? i'm really desperate :(

  • what does `ip addr`, `ip link` and `ip route` look like? – Zypher Mar 04 '15 at 23:12
  • `[root@server NetworkManager]# ip addr bash: ip: command not found [root@server NetworkManager]# ip link bash: ip: command not found [root@server NetworkManager]# ip route bash: ip: command not found [root@server NetworkManager]#` – redireccion Mar 04 '15 at 23:14
  • I've also noticed that Network or NetworkManager it's not running on my server, I've been reading about it and this might be the answer – redireccion Mar 04 '15 at 23:16

  • Can you use `ifconfig`? I find it strange that the `ip` command is not found on a Cent 6 box. – Zypher Mar 04 '15 at 23:20
  • ifconfig just shows nothing, adds another line – redireccion Mar 04 '15 at 23:22
  • Whelp yep your network stack sounds jacked - out of curiosity did you reboot after running yum update? – Zypher Mar 04 '15 at 23:23
  • Yes I did because I tho that rebooting would help to get back online, but it didn't... – redireccion Mar 04 '15 at 23:25
  • I would check `dmesg` and your system logs in `/var/log` to see if there is any idication as to why the nic is missing – Zypher Mar 04 '15 at 23:26
  • Is there any way we can recover these services without reinstalling -yet- the droplet ? If we reinstall the droplet I know we'll get back online, but we'll lose the data :( – redireccion Mar 04 '15 at 23:29
  • 1) ask digital ocean to recover the data if they can or 2) Figure out why the nic isn't being seen by looking at your logs. – Zypher Mar 04 '15 at 23:32
  • We're not on digitalocean and yes, seems that everything got deleted... http://pastebin.com/2wkqGiQi – redireccion Mar 04 '15 at 23:38
