The following python code hangs on executing cmd2 (works with cmd1). The commands works fine when executed on a shell. I have the same problem with Python 2.3.4 and 2.4 (Windows). I use the latest Cygwin binaries import os cmd1 = "bin\\ssh" cmd2 = "bin\\ssh -i id_dsa admin@myserver.com uptime" def docmd(cmd): print "Doing %s ..." % cmd (stdin, stdouterr) = os.popen4(cmd) for line in stdouterr.readlines(): print line stdin.close() stdouterr.close() print "Done." if __name__ == '__main__': docmd(cmd1) docmd(cmd2) Give me some advice for testing (popen, linux, ...).

Logged In: YES user_id=86216 AFAICT, this works for me under Cygwin 1.5.18 and Python 2.4.1: $ python /tmp/sf.py Doing ssh ... usage: ssh [-1246AaCfgkMNnqsTtVvXxY] [-b bind_address] [- c cipher_spec] [-D port] [-e escape_char] [-F configfile] [-i identity_file] [-L [bind_address:]port:host:hostport] [-l login_name] [-m mac_spec] [-O ctl_cmd] [-o option] [-p port] [-R [bind_address:]port:host:hostport] [-S ctl_path] [user@]hostname [command] Done. Doing ssh -i id_rsa server uptime ... 8:29am up 1 day(s), 1:53, 5 users, load average: 0.41, 0.52, 0.59 Done. Note I changed cmd1 and cmd2 also follows: cmd1 = "ssh" cmd2 = "ssh -i id_rsa server uptime" I'm closing this bug report. Please reopen if this is still a problem.
