Thanks, Phil, for your help. I have just placed your script (that I also name as 'ntpd') ----------------------- #!/bin/sh # scripts in the /etc/NetworkManager/dispatcher.d/ directory # are called alphabetically and are passed two parameters: # $1 is the interface name, and $2 is "up" or "down" if [ "$1" = "eth0" ] then if [ "$2" = "up" ] then /sbin/service ntpd start fi if [ "$2" = "down" ] then /sbin/service ntpd stop fi fi ----------------------- in /etc/NetworkManager/dispatcher.d/. Moreover, I did the following: chmod 755 ntpd /sbin/chkconfig ntpd off but, after a reboot, I get nothing with # ps -A | grep ntpd # So, I suspect that ntpd was not called by the script. Any ideas?
