I say semi-consistently, because it's not happening on all of our machines, but it is consistent for any of the problem machines. Furthermore, the command must actually produce output to standard out. The remote command is actually finishing, and as a far as I can tell, is terminating cleanly and correctly. Here is an easy way to reproduce it: ssh user AT remote-host ls -a | wc -l The following work fine: ssh user AT remote-host ls -a ssh user AT remote-host ls -a >/dev/null My cygcheck.out file is attached. ssh reports it's version as SSH version OpenSSH_3.9p1, OpenSSL 0.9.7e 25 Oct 2004 The destination host does not appear to matter (I've tested against cygwin-sshd, and a linux box). This has my very baffled, and concerned. Any help appreciated.
