I have a problem using sshd on cygwin: the backspace key does not work as
expected, for example in vi (inserts ^? ) and cat. To get it working I
have to press Ctrl+H. Bash prompt behaves properly (therefore I assume
that readline interprets the keycode better). Also, local bash prompt (not 
using sshd, just starting ...\bin\bash.exe works ok (even with 
.bash_profile setting TERM to linux)

Environment: 
- latest (updated) complete cygwin version installation, 
- ssh client Putty (also ShellGuard -- former TelNeat), 
- TERM=linux (for shellguard) or xterm (for Putty)

There are some ways to get it working properly:
- using putty, I can configure backspace to send Ctrl+H
- if I open ShellGuard to a linux machine (where BackSpace works ok) then 
ssh to cygwin machine, it works again.

I am not very sure, but I *think* this occured recently, after (for 
example) updating cygwin's openssh, terminfo etc to latest versions.

I tried playing with bs option in shellguard's termcap.ini but no success.

Ideas?


Thanks in advance,
rudy

Is this ssh-ing out of your cygwin box or into it?

In either case, the problem is a tty configuration mismatch between where
you are (ssh nnnnn) and where you're going (running the shell).

Use

  stty -a

to see how your current settings are (look particularly for "erase") and
then

  stty erase NN

to set it as you wish (say ^ and ? or perhaps ^ and h).

If you always send delete, then you can just put

  stty erase ^?

into your .profile (or .bash_profile or .bashrc or whatever it is if
you're coming back into your cygwin box; I haven't figured it out under
cygwin yet) and that will force the matter.

Another thing that folks sometimes do is whip up a simple script actually
named ctrl-h or ctrl-questionmark and put the relevant stty commands
in there; when you hit the backspace key at the prompt, you'll either
properly try to back up and do nothing or spit out a wonky character,
which the shell will interpret when you hit return and away you go :-)
I don't recommend it (these things should really be negotiated better,
and your term settings should be transparent) but it's a useful kludge.

Many thanks, David, for that stty hint - that solves a problem I have lived with
for quite a while - I haven't found any good introductions to the finer points
of terminals on the web.

Secondly, I'm beginninge to suspect that Outlook Express is allergic to PGP
signed mail. (It displays a blank mail, with the body in a .txt attachment and
the PGP sig in a .dat attachment.) I know that the obvious answer is to get a
better mail client, but does anyone have any workarounds in the mean time?

Max.

If you ask *really* nicely I can fold and mutilate my mail enough to
work for you, like I have this one, but you have, indeed, correctly hit
upon the obvious answer.  To keep this on topic, I suggest mutt under
cygwin :-)
