           Summary: sftp hangs when a tcsh user types quit or exit
           Product: Portable OpenSSH
           Version: 3.0.2p1
          Platform: UltraSparc
        OS/Version: Solaris
            Status: NEW
          Severity: normal
          Priority: P2
         Component: sftp
        AssignedTo: openssh-unix-dev at mindrot.org
        ReportedBy: andrewb at cs.mcgill.ca


When using sftp I found that when quiting the application, it would hang. It
exits when one does a ^C. I checked my .cshrc to make sure that ignoreeof was
not set or anything else that could be preventing me from exiting. I did the
test recommended for sftp/scp in the FAQ, that works at it should. I then asked
a co-worker to try and he had no problems. The difference between our 2 accounts
was that I use tcsh and he uses bash. I then set my shell to bash, and quit
worked without any problems.

Below is the output from running sftp in verbose mode:

Killed by signal 2.

I also downloaded and tried the snapshot of : openssh-SNAP-20020211.tar.gz
That had the same problem.

If any of you need more information please let me know.

Andrew.
