netstat is your friend.

To prevent startup, modify the scripts in /etc/rc.config.d

Example, for NFS, set the variables to 0 in nfsconf:

Instead of:

NFS_CLIENT=1
NFS_SERVER=1

Put:

NFS_CLIENT=0
NFS_SERVER=0

Kevin,
check the /etc/rc.log for which script starts which daemon.
or
run your greps against files in /sbin/init.d/

Modify the script in the /sbin/rc?.d directories.

Take care when disabling your daemons. No NFS ? No snmp ?

Hi Kevin:

You control the 'rc' scripts my editing the appropriate file in '/etc/rc.config.d/'. The variables in these scripts control the scripts run by in '/sbin/init.d/'. The sequence of the running is in turn controlled by the ordering of symbolic links in each run-level directory. For run-level three (3) that directory would be '/sbin/rc3.d/'.

The man pages for 'rc(1M)' offer a concise explanation of the paradigm. You can also read the excellent whitepaper:

Determine if the services are enabled to run at boot time by looking at the associated files in /etc/rc.config.d. The init scripts are in /sbin/init.d. Most of the config files have names matching the init script, but there are a few oddballs. (CDE is controlled in /etc/rc.config.d/desktop and rbootd is controlled from /etc/rc.config.d/netdaemons, for example.) Looking the script to see what variable it's using to control whether it starts the service will give you the search string and you can grep for it on the files in /etc/rc.config.d if it becomes necessary to track one of the oddballs down.

Hi,

# UNIX95=1 ps -o pid= -C
will return the pid of , if is running.

Per your question, substitute the following for :
* lpsched
* nfsd
* sendmail
* ptydaemon
* xfs
* snmpdm
* rbootd

rc script configuration is done through config files in /etc/rc.config.d. Run level based starting/killing is handled by symlinks in /sbin/rc?.d/ to init scripts in /sbin/init.d/.

hi kevin,

even if the scripts exists in the rc directories, the values set in the corresponding files in /etc/rc.config.d/ dictates whether they will be started or not.

Please find attached one interesting document which explains how this works. (nb. even if the document is old, the concept is still valid)

hope this helps too!

kind regards
