How does minicom write to /var/lock

Wim Sturkenboom · 10-24-2005, 05:17 AM

I'm trying to figure out how the minicon program can write to the directory /var/lock when it's executed by a normal user.

minicom is owned by root/uucp and the permissions are
-rwxr-xr-x.
/var/lock is owned by root/lock and the permissions are
drwxrwxr-x.
The user is neither a member of uucp nor of lock.

When running the program as a normal user, 3 files are created in /var/lock; they are owned by the normal user and the group is lock.

Can anybody explain? I've tried to figure it out from the sourcecode (of a newer version), but till now I'm stuck.

PS: OS=RH8

What user does the minicon process itself run as? If its a daemon it likely runs as root regardless of who owns the binary.

minicom is a terminal program

Code:

ps -ef |grep minicom
