Hello,

Okey, at this point, I've tried everything and still no luck.

I'm pretty sure it something I'm missing configuring the network. I've tried to use OpenVZ and Virtuozzo. I get the same results with both.

My problem, I install VZ, create the VE with OS, etc.. enter the one of the extra IPs, I got with the server (example: 70.22.201.192 - came as extra available ip with the server), setup a hostname, have it auto boot, and restart the VE. Everything is fine at this point, the VE starts, I can enter it using VZCTL ENTER 101.

Now I can't ssh into it using the IP, if I set something out of the blue, like 10.1.111.0.

Yes than I can ssh into it... now if I ssh into the VE from within the HN, I can look at the dirs, etc.. I just can't ping anything out or in. If I try to install cpanel, well nothing.

Anyone have a clue what I am missing.

Perhaps you haven't enabled IP forwarding? What does

cat /proc/sys/net/ipv4/ip_forward

shows? Should be 1.

I'm thinking maybe Im not entering the OpenVZ Kernel but the regular OS Kernel...

If you had entered the normal kernel it would not even load/start the vps.

Have you made sure you are setting the correct nameservers for the VPS, also do you have a firewall started, on the host node run service iptables stop.

Then try.

Hi,

Thank you to everyone for helping!

I will try all of the above tips, as for the nameservers, I think I am using the correct ones. Smile

Smile

Regarding correct Kernel, after installing OpenVZ, I just reboot the machine and than get the prompt again. Do I need the concole to select which kernel to use at boot up of the machine ?

Thanks again!

There should be more above those lines.

If there isn't, don't reboot your server.. Twisted Evil

Hello,

Actually there is. I don't think its a problem with Kernel, as I can create the VE and set ips, nameservers, etc... I can even enter the VE from the HN. The only think I can't do, is Ping anything from within VE, nor can I install cPanel if I wanted to.

When I do try to ping something from within the VE I entered into, all I get is blank space, looks like its waiting. Than I get no errors, just comes back to prompt.

Any ideas?

Hello,

Another update. Looks like I can't even ping the HN from within the VE.

*HN# vzctl set XX --ipdel all --save; vzctl set XX --ipadd x.x.x.x --save; ifconfig; route -n; iptables -L -n; iptables -L -n -t nat; cat /proc/sys/net/ipv4/ip_forward

*VE# ifconfig

--

run these in seperate terminals:

VE# ping 4.2.2.1

*HN# tcpdump -nvvv -p icmp

--

Paste the output of the commands starting with * and we should be able to see the networking problem.

it looks like your HN and VE both have the address of 75.126.166.16 , is this correct? since the HN and VE are different "devices" on the network, only one should have a given ip address.

Hi,

Actually no, the 75.126.166.16 is one of the free addresses I received when getting the HN. The HN has a different ip.
