[Bug 761] sftp not exiting in batch mode
http://bugzilla.mindrot.org/show_bug.cgi?id=761
Summary: sftp not exiting in batch mode
Product: Portable OpenSSH
Version: 3.6.1p2
Platform: All
OS/Version: AIX
Status: NEW
Severity: normal
Priority: P2
Component: sftp
AssignedTo: openssh-bugs at mindrot.org
ReportedBy: mmurra28 at csc.com
The root cause appears to be the way sshd parses it's configuration file and
subsequently processes exit codes from subprocesses (such as sftp-server).
When the sftp server exits , it passes either a signal or exit code back to
sshd, and then sshd should in turn drop the connection. sshd does not drop the
connection. However, when we switch LogLevel from INFO to DEBUG in
sshd_config, when sftp exits, sshd now exits properly. The only difference
here, is the processing thread within sshd's subsystem shell. We even
verified
different versions of the sftp-server subsystem, both with the same results.

http://bugzilla.mindrot.org/show_bug.cgi?id=761 ------- Additional Comments From dtucker at zip.com.au 2003-11-18 17:07 ------- Can't replicate either (AIX 5.2 ML1), with LogLevel either INFO or DEBUG3. Tried both a local and remote (Solaris 8) client. What version and maintenance level of AIX do you have? Can you replicate with both client and server on the AIX box? For that matter, can you replicate with the current version of OpenSSH? Can you attach (note: create attachment, not paste into comments) the debug output from sftp (eg "sftp -vvv -b testbatch localhost"). $ echo `uname` `oslevel -r` AIX 5200-01 $ ssh -V OpenSSH_3.6.1p2, SSH protocols 1.5/2.0, OpenSSL 0x0090702f grep LogLevel /usr/local/etc/sshd_config LogLevel INFO $ sftp -b testbatch localhost Connecting to localhost... dtucker at localhost's password: sftp> get /bin/ls /tmp/foo sftp> ls /tmp/foo /tmp/foo sftp> put /tmp/foo /tmp/bar Uploading /tmp/foo to /tmp/bar sftp> ls -l /tmp/bar -rwxr-xr-x 0 500 1 22488 Nov 19 11:00 /tmp/bar sftp> $ ps -eaf |grep sftp dtucker 2610 10118 1 11:00:27 pts/0 0:00 grep sftp ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee.
