I have an user named "myUser" and it's uid and gid is "170". This number is gid of another user named "avahi-autoipd" at same time. I try seperate this 2 users with usermod and groupmod commands. But there is another problem at this option.
My commands and their outputs like this:
[root@myHost test]# id myUser
uid=170(myUser) gid=170(avahi-autoipd) groups=170(avahi-autoipd),10(wheel)
[root@myHost ~]# usermod -u 666 myUser
usermod: warning: /var/spool/mail/myUser not owned by myUser
[root@myHost ~]# groupmod -g 666 myUser
[root@myHost ~]# chown myUser:myUser /home/myUser /var/spool/mail/myUser
[root@myHost ~]# ls -lt /home | grep myUser
drwx------. 16 myUser myUser 4096 May 29 09:50 myUser
drwx------. 3 41155 41155 87 Jan 2 2013 myUser1
[root@myHost ~]# id myUser
uid=170(myUser) gid=666(myUser) groups=666(myUser),10(wheel)
[root@myHost ~]# id avahi-autoipd
uid=170(avahi-autoipd) gid=666 groups=666
This state is not permanent. After like 5 minutes UID and GID of myUser and GID of avahi-autoipd changes to 170 again.
[root@myHost test]# id myUser
uid=170(myUser) gid=170(avahi-autoipd) groups=170(avahi-autoipd),10(wheel)
[root@myHost ~]# id avahi-autoipd
uid=170(avahi-autoipd) gid=170 groups=170
How can I seperate this 2 users and block generate new UID and GID for them?
