[Serusers] Can't restart my SER after eidting 'ser.cfg' - sr-users

10 Mar 2005


      Hi All,
Im a new user who is still learning.
Error: unable to restart the SER using 'service ser
restart' in the terminal after eidting the 'ser.cfg'
file. Below was the result shown in the terminal.
...
From terminal: Stopping ser: [FAIL]
Starting ser: [OK]
Seem like SER just wont stop even using 'service ser
stop'. Using 'service start' is ok.
Pls help....
This is my OS:
