RE: 1.5.12 ssh hangs on some machines when stdout has content

Try upgrading or even have a go with the current development snapshot (http://cygwin.com/snapshots) - it's in a testing cycle at the moment and it would be helpful to know if your problem is fixed (see also http://cygwin.com/ml/cygwin/2005-09/msg01020.html) cheers, DaveK -- Can't think of a witty .sigline today -- 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/

The current Cygwin is 1.5.18 (going on 1.5.19), and OpenSSH is up to 4.2p1. This list cannot afford to support more than the current version of Cygwin and tools. If you can still reproduce your problem after upgrading to the latest versions of Cygwin and OpenSSH/OpenSSL, please report back to this list.

Is there any direct/easy way to upgrade cygwin without user-interaction? The only way I know is to run the GUI install program, and that's going to be a big problem for us. Thanks David Yes. Upgrade one machine, and build an msi that updates the files, then distribute it via active directory. Alternatively, use your preferred packaging format. Failing that, update a machine, zip up the updated cygwin folder, and distribute it across your network onto each machine, using administrator rights to stop the ssh service before applying. I should point out that there is no guarantee that permissions would remain intact with either method.

I'm pretty sure it's not a permission problem cause if I run setup without any arguments it creates the log files just fine. The weirdest thing is that it worked once for me about 10 minutes ago.
