Hi Thomas,

Thanks for your reply.

Can we set child processes with correct PPID?

Regards, Philip

Hi Philip,

use this :

setuid = stunnel4 setgid = stunnel4

where stunnel4 is the name of the user you want the process to be run with.

Regards, Thoms.

I’m trying to setup stunnel listening to multiple ports. The PPID of processes created are always root. Can we change that to the right PPID?

Here I can see all the processes by killing 10764 and I expect this is the PPID. But all the children PPID are still 1;

UID PID PPID C STIME TTY TIME CMD philwong 10759 1 0 16:27 pts/78 00:00:00 stunnel self.conf philwong 10760 1 0 16:27 pts/78 00:00:00 stunnel self.conf philwong 10761 1 0 16:27 pts/78 00:00:00 stunnel self.conf philwong 10762 1 0 16:27 pts/78 00:00:00 stunnel self.conf philwong 10763 1 0 16:27 pts/78 00:00:00 stunnel self.conf philwong 10764 1 0 16:27 ? 00:00:00 stunnel self.conf

Hi Bri,

Right, the PPID of the parent process should be always 1. However, it sounds to me the PPID of the child processes should be the stunnel parent PID. With my example, if I kill PID 10764, all the stunnel processes will be gone. So I expect that's the parent, then the others should have PPID "10764". Isn't it?

Hi Thomas,

PPID is the parent process ID number, i.e. the PID of the process that ran you. When I am in bash and run 'ls', the PPID of ls is my bash shell.

This has nothing to do with the userid of any of these processes.

When your PPID is 1 that means that your parent has exited, and you have been inherited by the init process (process ID 1).

Sounds like you killed the parent stunnel process exited but the children continued on because they weren't done handling their requests. This is not abnormal.

Though it's not a big deal, I feel odd that I can't see the branch in my system... All children look like a self-contained process.

$ ps -efH

Yes, if the stunnel parent is still running.

Try 'ps -efH' and you can see the parent/child relationship as a nice indented tree.

I suspect you already killed the parent. All of these are children.
