Yes, but I need a check that certain known process's PID listens on a defined port. connect() would certainly work, but I may end up connecting to a different process. I forgot to mention that my master daemon starts processes in question as external applications, defines port they should bind but starts them via different user via sudo, which makes checking /proc/net/tcp not possible. Well, seems it's turning out not straight-forward, but thanks a lot for your thoughts anyway! Zdenek -- http://mail.python.org/mailman/listinfo/python-list
