[Feature Request] mention hostname on -v

[Philipp Marek]

I've got a usecase right now where I've got to use a few
intermediate ProxyJump hosts, and it would help debugging
via -v tremendously if the debug lines would have a prefix
of the originating host, so that they can be easily associated.


The FQDN might be too long, though -- perhaps just the PID
with an additional line associating it with the host would be
a better fit?


Thanks!

it's a bit of a hack, but you can get PID in debug messages right now
using LogVerbose=*, though you'll probably need to set it in ssh_config
if you're using ProxyJump as options from the command-line are mostly
not passed to the subordinate ssh processes.

Thanks for the idea -- but that means having write access to sshd_config
and (potentially) disturbing all other users on the machines.


Well, how about the general idea of including the PID?
If it's at the end like [1234] it's okay as well,
highlighting strings in an editor is easy enough.

Note that Damien wrote ssh_config[1], not sshd_config.
You can have a ~/.ssh/config to override system defaults.

Ah yeah, right. Sorry, I misread.
