ARCHIVED: From a Unix account, how do I connect to another shared computer?
You can use two different programs to connect to another shared Unix computer: telnet and SSH. Since telnet transfers all data unencrypted over the network (including passwords), UITS recommends that you use SSH if it is supported by the host to which you are connecting. At Indiana University, the central research systems at IU do not allow incoming telnet connections, so you will need to use an SSH client.
To connect using telnet, at the Unix prompt, enter:
telnet hostname
Replace hostname
with the name of the shared computer to
which you are connecting.
To connect using SSH, at the Unix prompt, enter:
ssh hostname
Replace hostname
with the name of the shared computer to
which you are connecting (e.g.,
quarry.uits.indiana.edu
).
In SSH, the first time two computers connect, the computer to which
your computer is connecting (the "remote host") must supply the
computer making the connection (the "local host") with its SSH host
key. In this case, you will get a message from the local host saying
that the host key was not found in the local database, and asking if
you wish to accept the key and continue the connection. Enter
yes
. To continue the login process, the remote host
will then prompt you for your password.
To connect via SSH to a remote host on which your username is different from your local username, enter one of the following commands:
ssh remotename@remotehost.com
ssh -l remotename remotehost.com
Replace remotename
with your username on the remote host,
and remotehost
with the name of the remote host.
For more, see About telnet or About SSH
Note: When you log out of the remote host, you will still be logged into your local host, so do not leave the local session unattended.
