Use "chkconfig" from the command line.
Thanks for info. Is this how we check if the entry made is correct? (correct me if I am wrong) Supposing if I add the smb service for run-level 3, I should look for the "smb" in /etc/rc3.d/ For example: # ls /etc/rc3.d/ | grep smb in my case it returns "S91smb", which I assume the service is added for this run level. Is this how we check? Othewise the only process I know is to run the machine in each run-level and check if the process is there. By the way what its that "S91" ? Thanks again
