Huh?

[roam@ringworld:v2 ~]$ ssh roam@localhost '/bin/echo "shell is $BASH_VERSION, SSH_CLIENT is $SSH_CLIENT"'
roam@localhost.office1's password:
shell is 2.04.0(1)-release, SSH_CLIENT is 127.0.0.1 1075 22
[roam@ringworld:v2 ~]$

This is on 4.2-stable with bash installed from the shells/bash2 port.
Are you sure you don't have anything in your profiles that unsets unknown
variables or something?

G'luck,
Peter
