I have setup a Centos Linux Server. I can connect to my server with command:
ssh My_Name @ Ip_Address How can I set a name for my server so that I can connect with the command:
ssh My_Name @ My_Server_Name.com The .com or '.net' does not matter, I just want to have a name for my server.
If you just want to do this for convenience, the simplest method is to add a stanza to your ssh configuration file ~/.ssh/config :
Host my_server_name HostName some_ip_address User my_name ... any other options Then you can ssh my_server_name to connect.
Other options include:
using mDNS and connecting to the .local name your machine advertises (mDNS is called bonjour in the Apple world; a common linux implementation is avahi).
editing the /etc/hosts file on each client machine to provide a mapping from the IP address to the chosen server name.
installing and configuring a DNS server on a machine in your local network, and setting it as the preferred DNS server for all other local machines.
IP_Address_1 and when I connect inside home [within my home network] I need to use IP_Address_2. So I want to set a name, so that I can always use a unique name wether in home or out of home. And to add a further possibility if you want a more general solution than just for your ssh connection, you could add the alias to your /etc/hosts file
IP address YourAlias1 ... This would allow you to use the alias with any other programs, but wouldn't include the ssh user name as the first answer gave.
