openssh bugs - Sep 2004 - [Bug 923] Connection closed after autentication

http://bugzilla.mindrot.org/show_bug.cgi?id=923

           Summary: Connection closed after autentication
           Product: Portable OpenSSH
           Version: -current
          Platform: ix86
        OS/Version: Cygwin on NT/2k
            Status: NEW
          Severity: critical
          Priority: P2
         Component: sshd
        AssignedTo: openssh-bugs at mindrot.org
        ReportedBy: jeslan89 at hotmail.com


The 3.9p1 version of the sshd server for cygwin can't be accessed from any
computer or localhost. It closes the session with a "connection
closed" message
and a 255 Exit code after the user is autenticated. It occurs with both password
and ssh keys. Tested with different computers with the same result and as I read
on "tech.erdelynet.com" forums I am not the only one with the same
problem.

  This is not happening if the latest 3.8 version is installed instead 3.9p1. It
works completely OK in that case. The problem is only encountered with 3.9p1
version.

The combination of UsePrivilegeSeparation (on by default) + reexec (also on by
default) apparently tickles a bug in Cygwin itself.

According to Corinna there are 3 ways to workaround that problem:

- Either switch off PrivSep,
- or use the -r option to switch off reexec'ing,
- or use one of the latest Cygwin developer snapshot from
  http://www.cygwin.com/snapshots/
  The bug should be solved since the 2004-Aug-19 snapshot.

Since this is not actually a bug with OpenSSH, I'm closing this.  Please
re-open
if you can reproduce with the updated cygwin DLL.
