domain names

[Archer Troy]

im trying to setup ssh with my netowrked computers.

Im using this guide: http://www.cyberciti.biz/faq/ubuntu-linux-openssh-server-installation-and-configuration/

In it it says i need a domain:

Assuming that your server hostname is userver.mydomain.com and username is vivek, you need to type the following command:

# ssh vivek@userver.mydomain.com

what dopes that mean. whats my domain. can i use my network ip address (ex. 192.168.1.101)

any help would be greatly appreciated..thanks

Yes you can use your ip address.

you domain is the name you give your computer. This will work on your LAN if you have a local DNS server or update your /etc/hosts on your clients.

A domain name is a public name for your ip address, like say ubuntuforums.org

If you want a public domain you need to use a free service like DynDNS or purchase one.
