Hi Folks,
	I have got ssh and sshd compiled with b19 but am having a few
problems.  I have been through the mailing list archives and learnt a
few things.

I am running : NT4.0SP3, gnuwin32B19, ssh 1.2.21 without kerberos
compiled in.

Looking through the archives I have tried a few tricks to get ssh
working such as:
+  from_stdin = 1;
in readpass.c at line 98.

This gets me going, but sometimes it still gives an exception when I run
it, and not others.  It is always after the password prompt comes up.

sshd gives the following when run without any command line options :
bash-2.01$ ./sshd
(E:\cygnus\Incoming\ssh-1.2.21\sshd.exe 1097) Exception:
STATUS_ACCESS_VIOLATION

Received signal 11.
bash-2.01$

Thats it, no chance to connect at all....

If I use the '-d' option and connect to it from another machine I get :

bash-2.01$ ./sshd -d
debug: sshd version 1.2.21 []
debug: Initializing random number generator; seed file
/etc/ssh_random_seed

error: Failed to disconnect from controlling tty.
debug: Received SIGCHLD.

On the remote machine I get when trying to connect :
(remotebox)[/] jjb> ssh 111.11.11.10
Environment:
  SSH_CLIENT=111.11.11.11 1021 22
  SSH_TTY=/dev/tty0
  CYGWIN_TITLE=1
  CYGWIN_TTY=1

And it hangs there....
(remote machine is SSH Version 1.2.20)

Is is something to do with my tty's not being setup?  I have nothing in
/dev, but I couldn't work out how to create any special files here
anyway, mknod tells me 'Function not implemented'

On a side issue there seems to be a bug with gdb or gunwin.  If I tried
:

"bash-2.01$ gdb ./ssh blah.com"

Then after you run it in gdb you get :

"Bad host name: ssh.exe"

seems as though the ARGV's are not getting translated properly
somewhere.  I would have looked at it further, but I haven't yet
downloaded the source.

Thanks in advance for any help,

JB.
