I just got my own server that I am colocating at a datacenter. It's a 1U rackmount server with Ubuntu 9.04 and I've been given the two IPs, Gateway, Subnet, and DNS information from the datacenter. They said it must be preconfigured, as I'm shipping it to them. However, I'm not familiar with how I can set it up and make sure it's working alright before I ship it off. The biggest thing I need to make sure is that I can at the very least access SSH but I'd prefer to be able to connect to remote desktop. Any tips or help for me? Thanks!
An approach that takes the least amount of equipment:
You will need another computer and a switch. Your broadband router will do.
Configure your server as specified.
Then, without removing your current ip settings, on your computer add as an additional address the gateway ip with the same netmask. Do not enter an additional default gateway. The purpose of doing this is to make the computer simulate the router path.
Plug both into the same switch.
From the server, ping the gateway address, ping the normal address of the other computer. You should get an answer for both.
From your computer, ping the server, you should get an answer.
If this passes, then setup sshd on the server a ssh client on your computer. Try to login from the computer.
This does not cover any particular OS, or security. Just getting to a point where you are comfortable that the ip, subnet and gateway are correctly set, and that SSH is available.
To make sure that it all works, you must shutdown the server after the tests, bring it back up and have everything work without any additional prodding because this is what the data center will do.
BTW, make sure you have the correct duplex and speed settings for your card and the switch at the data center.
