Starting daemon at boot up

Buto · 09-07-2004, 06:16 PM

I am running Slackware 10 using runlevel 3 and was wondering how to start two daemons on boot up, ie the Samba daemons. When I turn on my PC I want the daemons running without having to login, so the daemons are running when the login prompt appears.

Also how do I get these daemons running under a certain user, like when they spawn during boot up the belong to a user called Samba. Thanks for any help.

For the Slackware correct way

You need something like this in your /etc/rc.d/rc.M file:

Code:

# Start Samba (a file/print server for Win95/NT machines).
# Samba can be started in /etc/inetd.conf instead.
if [ -x /etc/rc.d/rc.samba ]; then
  . /etc/rc.d/rc.samba start
fi

And then you need a file called rc.samba in /etc/rc.d/ that is executable:

Code:

#!/bin/sh
#
# /etc/rc.d/rc.samba
#
# Start/stop/restart the Samba SMB file/print server.
#
# To make Samba start automatically at boot, make this
# file executable:  chmod 755 /etc/rc.d/rc.samba
#

samba_start() {
  if [ -x /usr/sbin/smbd -a -x /usr/sbin/nmbd -a -r /etc/samba/smb.conf ]; then
    echo "Starting Samba:  /usr/sbin/smbd -D"
    /usr/sbin/smbd -D
    echo "                 /usr/sbin/nmbd -D"
    /usr/sbin/nmbd -D
  fi
}

samba_stop() {
  killall smbd nmbd
}

samba_restart() {
  samba_stop
  sleep 2
  samba_start
}

case "$1" in
'start')
  samba_start
  ;;
'stop')
  samba_stop
  ;;
'restart')
  samba_restart
  ;;
*)
  # Default is "start", for backwards compatibility with previous
  # Slackware versions.  This may change to a 'usage' error someday.
  samba_start
esac

And I'm not sure why you'd want samba to start as another user but you can pass a su <username> -c <command> for the actual command to start as another user, etc.

Also in slackware, if you installed Samba during initial install or used the tgz slackware packages to install Samba, you can edit your /etc/inetd.conf file as well to start the daemons.

if you installed samba just cd to /etc/rc.d and as root chmod 0755 rc.samba... sh rc.samba start and samba will be running and run at boot... this applies to any rc script in /etc/rc.d... the rc.M script is set up to start the scripts if they are excutable and to ignore them if not... pretty simple...
