Good suggestions,

You may want to check for things such as PATH information as it could be that when executing the script it can't find python executable. One

$PATH did include the directory where the python bin was stored, and actually specifying a full path like:

`/usr/local/bin/python /home/mailman/bin/list_lists`

still doesn't give me any output.

possible idea is try executing your command in a fasion like:

system("myprogram arg1 arg2 2>&1");

This may help by showing any output that gets sent to stderr on stdout.

Even better suggestion! This gives me:

Traceback (most recent call last): File "/usr/local/mailman/bin/list_lists", line 108, in ? main() File "/usr/local/mailman/bin/list_lists", line 86, in main mlist = MailList.MailList(n, lock=0) File "../Mailman/MailList.py", line 79, in __init__ File "../Mailman/MailList.py", line 879, in Load File "../Mailman/MailList.py", line 856, in __load IOError: [Errno 13] Permission denied: '/usr/local/mailman/lists/myfirstlist/config.db'

Which makes sense. The config.db file is 660 root.mailman. I guess that is why all the mailman CGIs run with setgid mailman. I guess that leaves me at an impasse. I probably shouldn't give the web server elevated permissions for my little hacks.

Thanks for your help in any case.

Hey,

I was trying to wrap several of the Mailman CLI tools (list_lists and such) in a little PHP so I could easily integrate them into a larger web site. Using PHP's System() function and the backtick operator to exec the Mailman tools never seems to result in any output, but no errors either. However, I can drop a script of my own (a little Perl hack or whatever) in the ~mailman/bin directory with the same ownership and permissions, and it seems to exec just fine.

Any idea what I'm overlooking?

Add your www user to the mailman group...

You should *not* do that. That gives the normal webserver way too much permissions. You should just use a setuid mailman wrapper script that does caller-checking to see if it's called correctly, by the right user, and with 'safe' values.
