Unresponsive Openvz Vps
So here's my story. I have an Openvz vps running Centos 6 from nodeserv. I rented it as a backup server. Since the past week it has stopped responding and I cannot login via ssh or ftp using the server IP. Funny thing is Solusvm says the server is online, alive and kicking and I can ssh into the server using the Solusvm serial console credentials but that is all I've got for the moment. I cannot ping to any ip from the vps either. Steps I've taken so far in vain:
- Rebooted the vps.
- Reconfigured Networking via Solusvm.
- Disabled iptables and csf.
- Submitted a ticket to the provider with no response.
I've got some backup files there and I've tried to scp, sftp etc. using the Solusvm console IP and username but it didn't work. The problem probably is network-related but is there any way I can get around this and download my backup files?
Comments
So the VPS has no network connectivity at all? Basically cut off from the internet?
This is a hard one, I'm not entirely sure, at least you have serial console access
Yes it looks like it because it cannot ping to any ip from within (Pinging to the server ip from multiple locations doesn't work either).
I have a VPS with NodeServ and I've just had one problem after another for a long time (after Jade left, around the time it was acquired).
In all probability the routing is all messed up and they'll have to assign new IPs for your VPS. Reach out via ticket to get it sorted out.
I suspect that it is also no longer in Jacksonville (in my case I've been moved to Seattle).
Currently IPv4 and/or IPv6 is broken intermittently as well. It's pretty much an unusable VPS (and it has been unusable for over 4 months now because of horrible IO when it was in Jacksonville).

Whats ur /etc/network/interfaces
nano and paste that here.
No such file or directory. This is on Centos 6. Or am i missing something? I have /etc/sysconfig/network-scripts/
Ah.
Well, ifconfig looks normal to me.. at least I can't spot anything too odd.. venet0:0 is your adapter and it seems to be enabled.
/etc/resolv.conf?
Sounds like you have been null routed, can you even ping the gateway?
I've pinged a couple of IPs on that subnet and they reply including the possible gateway (107.155.188.1)
@AnthonySmith beat me to it. It's nullrouted.
@doughmanes said:
Generated by NetworkManager
search mydomain.com
No nameservers found; try putting DNS servers into your
ifcfg files in /etc/sysconfig/network-scripts like so:
#
DNS1=xxx.xxx.xxx.xxx
DNS2=xxx.xxx.xxx.xxx
DOMAIN=lab.foo.com bar.foo.com
There is a # before every line and yes I cannot ping the 'possible gateway'. Anyway, it baffles me that someone would target a backup server and have the provider nullroute the ip
Anyway, thank ya all for chippin in.
Did you solved the problem please ? i have similar problem, did you got any answer from the support ?
