You may have an alternate way of setting PS1 at the client, though the server may be configured to ignore it. The ssh man page says this on my system:

For more information, see the PermitUserEnvironment option in sshd_config(5). -y On Mon, Jun 11, 2018 at 9:29 AM, Michael Albinus <[email protected]> wrote: > John Collins <[email protected]> writes: > > > Hello, > > Hi John, > > > Happy (mostly) tramp user here that is also very new to it.
