I have a problem with subprocess.Popen and I believe that these are pipes. I have the following code block that works without problems in 100% of cases when launched from cli:
p = subprocess.Popen("psexec \\\\" + serverName.get() + " cmd /c \
ver & \
echo %USERDOMAIN% & \
dir /a C:\pagefile.sys | find \"pagefile.sys\" & \
dir C:\ | find \"bytes free\" & \
dir D:\ | find \"bytes free\" ", \
stdin=None, stdout=subprocess.PIPE, stderr=None)
results = p.communicate()[0]
rc = p.returncode
print 'results: ' + str(results)
sys.exit()
Conclusion:

I had this program finished, but as soon as I compiled it with py2exe, it just hung or crashed. I tracked this problem until py2exe not loving undefined stdin, out or err in a subprocess. Then I changed my code as follows:
p = subprocess.Popen("psexec \\\\" + serverName.get() + " cmd /c \
ver & \
echo %USERDOMAIN% & \
dir /a C:\pagefile.sys | find \"pagefile.sys\" & \
dir C:\ | find \"bytes free\" & \
dir D:\ | find \"bytes free\" ", \
stdin=subprocess.PIPE, stdout=subprocess.PIPE, stderr=subprocess.STDOUT)
p.stdin.close()
results = p.communicate()[0]
rc = p.returncode
print 'results: ' + str(results)
sys.exit()
This code also works in 100% of cases, but when I print the results, it shows only standard psexec messages, and not the output of executed commands.
