Hello i just setup a fresh dedicated server i'm trying to make a vps.

I successfully created the vps and i can enter it via vzctl enter

but i cannot access the server from the ip that i allocated it.

I dont think that the ip configuration on the node is setup for the ips that i will be using to make the vps.

Is there a specific file where i need to add the ips that i own so that they will work correctly when im creating vps's?

Sorry, I don't quite undestand you... What is "server" in your post? Is it host node or VE?
Can you descibe please what do you do in details and what fails?

You have to give only the following command:

# vzctl set <VEID> --ipadd <IPADDRESS>  --save

to start network inside VE. This <IPADDRESS> will be stored in <VEID>.conf file in /etc/vz/conf/ directory.

HTH,
vass.

In older versions of vzctl .conf files reside in /etc/sysconfig/vz-scripts/ directory. In this I suggest to you to upgrade to newer version.

You didn't answer my question concerning how you can't connect to VE. Please, describe your network configuration, what do you do to test connection. Provide /proc/sys/net/ipv4/ip_forward output, ifconfig inside VE and on HN.

Thanks.

Chris, you don't need to specify subnet mask for the IPs you are giving to your VEs as it is point-to-point connection with your HW node. Just add them to VE using "vzctl set <VPSID> --ipadd x.y.z.w --save" and check the connectivity.

If that doesn't work, provide outputs of the following commands on HW node (server):

# ip a l
# vzctl exec <VPSID> ip a l
# cat /proc/sys/net/ipv4/ip_forward
