Re: [gftp] using ssh to connect to a Sun file server

[Brian Masney <masneyb@gftp.org>]

Hi,
   I improved the SSH login code for the upcoming 2.0.18 release. You do not
have to know the remote path to the sftp-server binary, nor does gftp have
to send the echo xsftp command in front of sftp-server. It should just work out
of the box for you. You can download my latest code at
