Re: [h-e-w] ssh fails with "Bad file descriptor" on Interix (SFU)

[Robert Lerche]

Wow, Interix!  I gave up on Interix quite a while ago but I can confirm a similar issue, running NTEmacs but using ssh and friends built using MinGW/MSYS.  I was never able to get interactive ssh to work correctly in an Emacs shell window (using MSYS bash as the command shell) -- it hung as AKF_SDS described.

I did get bash to work fairly smoothly for almost everything else (including correct file name completion); I can offer a few hints on that subject if anyone is interested.

You could say _that_ again!

You are talking to Emacs users on Windows, but both your problem and
the data you present are from Unix.  You are unlikely to find here
anyone who could interpret that data, let alone correlate it with
something that is caused by Emacs on Windows.

You may have better luck attaching a debugger to ssh when it hangs and
finding out the reason why it hangs.  Then, perhaps some ssh developer
could tell you what might be the possible reason(s) for that.  Only
then, maybe, it would be possible to see how all this is related to
Emacs and/or Windows.

Sorry.
