How to restart inetd service in Linux

Learn how to restart inetd service in Linux. Xinetd service is a replacement for inetd service in new Linux versions.

inetd is internet daemon. Inetd is responsible for internet services like telnet, pop3, ftp, etc. Whenever a packet comes over the network to a server on a particular port, inetd is responsible to check it and launch the appropriate program to handle the connection request. For checking port information and its related services it consults /etc/services file.

# /etc/init.d/inetd start

Stop inetd service

# /etc/init.d/inetd stop

Restart inetd service

# /etc/init.d/inetd restart OR # killall -HUP inetd

All inetd configuration can be found in file /etc/inetd.conf
