>Description:

When I log in on a virtual console, stty -a shows ^H as the erase character.
When I ssh to the same or different RELENG_4 machine, stty -a still shows ^H
as the 'erase2' char, but the 'erase' char is ^?.

>How-To-Repeat:

Script started on Sun Apr 15 20:48:19 2001
[roam@ringworld:p0 ~]$ stty -a | fgrep -w erase
	eol2 = <undef>; erase = ^H; erase2 = ^H; intr = ^C; kill = ^U;
[roam@ringworld:p0 ~]$ ssh -t ringworld 'stty -a | fgrep -w erase'
roam@ringworld's password: 
	eol2 = <undef>; erase = ^?; erase2 = ^H; intr = ^C; kill = ^U;
Connection to ringworld closed.
[roam@ringworld:p0 ~]$ exit
exit

Subtly annoying ;)

>Fix:

No idea.. I tried tracing the ssh client, substituting all calls to tcsetattr()
with calls to a new wrapper function, so I can place breakpoints - nothing.
It seems the problem is with the server, somewhere along the login procedure..
