If this works, then it may be mtu issues where a router is dropping ip fragments. The third comment is a long shot, but I've actually experienced it before. -dave -----Original Message----- From: Brett Porter [mailto:brett DOT porter AT gmail DOT com] Sent: Monday, January 10, 2005 3:09 AM To: cygwin AT cygwin DOT com Subject: SSH client hang running uncompressed tar on various servers Hi, I'm having a problem with my SSH client hanging executing a remote command extracting an uncompressed tar. This occurs on different servers (FreeBSD, localhost Cygwin SSHD, RHL9), though they are all SSH2 and I've using the same private DSA key. Given this, it isn't the tar executable (though I turned off my virus scanner just in case). I know this has worked in the past, though I'm not sure at what point it may have stopped. It happens on both my machines, and I've had reports from other cygwin users using Maven. Does anyone have any ideas, or seen it happen? I've had trouble finding anything beyond virus scanners in the archives and documentation. The SSH version: OpenSSH_3.9p1, OpenSSL 0.9.7e 25 Oct 2004 1114k 2004/11/10 C:\cygwin\bin\cygwin1.dll Cygwin DLL version info: DLL version: 1.5.12 (I'm at the latest of what's installed - if there is any more info I could provide, please let me know). The exact command run is: ssh -vvv -l brett www.apache.org 'cd /home/brett/test-dir;tar xf maven-site- plugin-1.6-SNAPSHOT-site.tar'"/> The output with -vvv is: [exec] debug1: Authentication succeeded (publickey).

I have to kill the process - Ctrl-C doesn't work. BTW, I'm back to the cygwin list after a long time away - it's been so stable for years. Great job all - I couldn't work day to day on Windows without it :) Cheers, Brett -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
