I need to set up a fenced environment in on Ubuntu server. The actual use case is to have two separate websites running on the same physical box, but I want one of those websites running in a fenced environment. I figured that the best way to do this was create a VM on the server for the fenced website, and have a second IP address point to that VM.

A friend recommended OpenVZ, but this topic recommended LXC instead. I've got LXC working, except for the networking part.

I have a separate IP address and a separate MAC address, provided by the server provider (Hetzner). Unfortunately, I cannot figure out what values to put in the LXC config file so that when the container starts, it uses the different IP address.

When I start the container with below settings, it boots up fine. However, doing a curl http://curlmyip.com, I get the IP address of the root machine (188.40.88.211) and not the new IP (188.40.88.228). The latter IP does not respond to ping or http requests.

Here's the relevant bits from the config file:

lxc.network.type=veth
lxc.network.link=lxcbr0
lxc.network.flags=up
lxc.network.hwaddr = 00:50:56:00:30:3F
lxc.network.ipv4 = 188.40.88.228

Please let me know if there's any additional information I can give you, or even if I'm on the wrong track with the VMs. I'm very new to all of this!

I've got an old crusty WHM/cPanel server which I'm trying to get rid of. I've got a new setup on shared hosting which is much cheaper in the long run.

The problem is that there are a bunch of websites on the server whose domains I don't have access to. They're currently pointing to name servers of my domain (ns.mydomain.com), but the new provider has their own name servers (ns.provider.com) which I have to use instead.

My initial idea was to set up a CNAME to point my name server to my provider's: ns.mydomain.com CNAME ns.provider.com, but I read in this question that this would be a bad idea. The accepted answer suggests using an A record instead, and I want to make sure how this would work.

Assuming ns.provider.com has an IP address of 123.123.123.123, is it just a matter of doing ns.mydomain.com A 123.123.123.123? Is there any way the provider could block those requests as the name server domain technically doesn't belong to them?

We just got our new server(s) up and we're running CentOS on them all. After successfully installing Ruby Enterprise Edition, I would now like to add the REE /bin (located at /usr/lib/ruby-enterprise/bin) directory to make it the default Ruby interpreter on the server.

I have tried the following, which only adds it to the current shell session:

export PATH=/usr/lib/ruby-enterprise/bin:$PATH

What would be the correct approach to permanently adding this directory to $PATH for all users? I'm currently logged in as root.

centos shell root configuration path
