[mosh-users] Mosh session logging

[Andrew C Aitchison]

I use mosh to connect to a ubuntu machine.
I had scripts which could tell me whether a session came from
my phone or my tablet (assuming it was initiated on the local
network), but recently bit rot has set in.

The fundamental problem is that for a roaming protocol,
the ip address does not identify the client device.

First the transition to 64bit time with Ubuntu Oracular 24.10,
meant a switch from wtmp to wtmpdb and pam stopped recording the pty
so that `last` just said 'ssh' in the terminal column.

Now Ubuntu Plucky 25.04 has broken `who`
https://discourse.ubuntu.com/t/plucky-puffin-release-notes/48687#p-120902-systemd-v2574-8
as "systemd is no longer built with utmp support".

I'm wondering whether adding a pam module or config for mosh
is the way to go ?

Does anyone else have experience, thoughts or ideas on logging mosh 
sessions on current OSes ?

Thanks,
