ssh troubles

[Raman Gupta]

Oh I forgot the cygcheck output, here it is attached.

Also sshd is working right now, but this log was last written at some point
in the past when it wasn't:

$ cat /var/log/cygsshd.log
      0 [main] sshd 232 dofork: child -1 - CreateProcessW failed for
'C:\cygwin64\usr\sbin\sshd.exe', errno 30

Regards,
Raman
