...to 64K, rather than keeping them at their default values of 8K which thwarts data transfers a lot. While testing I still had the problem that for some reason the ssh read transfer rates were only a third up to a half of the write transfer rates. It turned out that the culprit was ssh itself. In clientloop.c, it defines read buffers of the size 8K. Setting them to 64K under Cygwin raises the read transfer rates comparable to the write rates. It occured to me that we talked about this already 3 years ago in a thread about HPN-SSH, just the performance numbers were different: http://marc.info/?l=open...

...oblem and patch reported to Red Hat Bugzilla by Jonathan Kamens <jik at kamens.brookline.ma.us>. I'm just acting as a relay :-) jik has experienced some weird crashes relating to window size changes or some similar activity. These are rather hard to trace. Problem was fixed by patching clientloop, where fd_set structures appear to be improperly zeroed (bytes vs bits). FD_ZERO does not appear to work as fd_sets are just pointers in this case, so alternative method is used. Patch by jik attached (does not apply cleantly to CVS but the idea should be apparent). -- Pekka Savola...

Hi folks, Could you tell me which function in clientloop.c is responsible for reading user keyboard input? What I found are client_make_packets_from_stdin_data() and client_process_input(), but they not for 'compat20' mode. My app runs in 'compat20'. Thanks, Bob

Hello, I just ran upon this problem and couldn't find it in bugzilla. SSH crashes (abort trap) if all of the following conditions are met: (a) option -f is used (crash happens when going to background), (b) reverse port forwarding is set up (option -R), (c) option ExitOnForwardFailure is enabled, (d) there are no actual port-forwarding failures. The problem can be reproduced by

...00' | (sleep 3 ; wc -l) With openssh 2.5.2p2 this correctly returns "2000". With 2.9p1 we get Write failed flushing stdout buffer. 1024 This is on both Linux (RedHat 7.0) and Irix (6.5.11). Investigation reveals that this problem was caused by the addition of lines into clientloop.c that force non-blocking mode onto the stdout channel.
