We want the cygwin bash shell while getting connected using Fortress SSH. So we installed Cygwin 1.7 and Fortress SSH Server on the windows 2012 R2 server.
- Configured the Console Settings in the Local Server Configuration to get the Cygwin bash shell.

When we tried ssh to the Windows server, we are getting the Cygwin shell. But, the issue is most of the cygwin commands returned "Segmentation Fault"

$ ls
Segmentation fault

$ ls -l /cygdrive/c
Segmentation fault

This is the Cygwin version:
$ uname -a
CYGWIN_NT-6.3 Server1 1.7.32(0.274/5/3) 2014-08-13 23:06 x86_64 Cygwin

Fortress SSH Server Version:  5.0 Build 9 Revision 2748

Can you please check what is the cause for this issue?

Regards
Swami
