It's been a few years ago, but I ran into a similar situation with
my shell account... I was able to connect with the AmigaOS console
and SSH client, but the server didnt recognize the Amiga's ANSI mode.
I don't recall the specifics, but I found the source of the Amiga
termcap files here:
http://www.catb.org/~esr/terminfo/ ...and by cutting out the Amiga modes and using the "tic" command
on my shell account, I was able to use the source above to make the
missing term types.
Then you just need to add a path to SSH, setenv for HOME, USER, TERM
in your u-s and you should be able to run a shell session with the
AmigaOS console.
Good luck,
