Install xinetd by running the following commands:
./configure --prefix=/usr && make && make install |
./configure --prefix=/usr: Change the default installation directory of /usr/local.
Create the xinetd.conf file with the following commands:
cp /etc/xinetd.conf /etc/xinetd.conf.bak |
Insure the path to all daemons is /usr/sbin, rather than the default path of /usr/etc:
sed -e 's/etc/sbin/g' xinetd/sample.conf > /etc/xinetd.conf |
The format of the /etc/xinetd.conf is documented in the xinetd.conf man page. Further information can be found at http://www.xinetd.org.
Create the xinetd boot script:
cat > /etc/rc.d/init.d/xinetd << "EOF"
#!/bin/bash
# Begin $rc_base/init.d/xinetd
# Based on sysklogd script from LFS-3.1 and earlier.
# Rewritten by Gerard Beekmans - gerard@linuxfromscratch.org
source /etc/sysconfig/rc
source $rc_functions
case "$1" in
start)
echo "Starting xinetd..."
loadproc /usr/sbin/xinetd
;;
stop)
echo "Stopping xinetd..."
killproc /usr/sbin/xinetd
;;
reload)
echo "Reloading xinetd..."
killall -HUP xinetd
;;
restart)
$0 stop
sleep 1
$0 start
;;
status)
statusproc /usr/sbin/xinetd
;;
*)
echo "Usage: $0 {start|stop|reload|restart|status}"
exit 1
;;
esac
# End $rc_base/init.d/xinetd
EOF
chmod 754 /etc/rc.d/init.d/xinetd |
Add the run level symlinks:
ln -s /etc/rc.d/init.d/xinetd /etc/rc.d/rc0.d/K49xinetd && ln -s /etc/rc.d/init.d/xinetd /etc/rc.d/rc1.d/K49xinetd && ln -s /etc/rc.d/init.d/xinetd /etc/rc.d/rc2.d/K49xinetd && ln -s /etc/rc.d/init.d/xinetd /etc/rc.d/rc3.d/S23xinetd && ln -s /etc/rc.d/init.d/xinetd /etc/rc.d/rc4.d/S23xinetd && ln -s /etc/rc.d/init.d/xinetd /etc/rc.d/rc5.d/S23xinetd && ln -s /etc/rc.d/init.d/xinetd /etc/rc.d/rc6.d/K49xinetd |
Now, we'll use our new boot script to start xinetd:
/etc/rc.d/init.d/xinetd start |
Checking the /var/log/daemon.log file should prove quite entertaining. This file may contain entries similar to the following:
Aug 22 21:40:21 dps10 xinetd[2696]: Server /usr/sbin/in.rlogind is not executable [line=29] Aug 22 21:40:21 dps10 xinetd[2696]: Error parsing attribute server - DISABLING SERVICE [line=29] Aug 22 21:40:21 dps10 xinetd[2696]: Server /usr/sbin/in.rshd is not executable [line=42] |
These errors are due to the fact that we don't have most of the servers that xinetd is trying to control installed yet.
