Install xinetd by running the following commands:
./configure --prefix=/usr && make && make install |
./configure --prefix=/usr: Change the default installation directory of /usr/local.
/etc/xinetd.conf
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.
The xinetd package contains xinetd, itox and xconv.pl.
xinetd is the Internet services daemon.
itox is a utility used for converting inetd.conf files to xinetd.conf format.
xconv.pl is a Perl script used for converting inetd.conf files to xinetd.conf format, similar to itox.
