SSH – Open File from Remote Computer on Host Computer

remotessh

I'm trying to edit a file from a remote computer connected via ssh. How can I open the remote file on my local computer to edit?

Best Answer

You can mount the remote directory with sshfs, after that, the file is accessible in your local directory tree.

Example:

sshfs user@domain:/remote/directory/ /local/directory/

It's all in the man pages.

Or just copy the file over with scp/rsync, edit it, and copy it back.

If both systems have the public key of your local system use -A.

From ssh(1)

-A      Enables forwarding of the authentication agent connection.  This
        can also be specified on a per-host basis in a configuration file.

Also be aware of this warning:

        Agent forwarding should be enabled with caution.  Users with the
        ability to bypass file permissions on the remote host (for the
        agent's UNIX-domain socket) can access the local agent through the
        forwarded connection.  An attacker cannot obtain key material from
        the agent, however they can perform operations on the keys that
        enable them to authenticate using the identities loaded into the
        agent.

The result is that when you auth against the second host the auth is forwarded all the way back to the host where you physically reside.

Example:

me@host0:~ $ ssh -A host1
Last login: Thu Jun 14 11:31:53 2012 from 2001:db8::b0
me@host1:~ $ ssh -A host2
Last login: Thu Jun 14 11:41:05 2012 from 2001:db8::b1
me@host3:~ $ ssh -A host3
Last login: Tue Jun 12 10:46:50 2012 from 2001:db8::b2
me@host3:~ $
