The chrctcp command

The chrctcp command in not documented in AIX, but you can still use it to do nice things, especially when you are scripting. Some examples are:

To enable xntpd in /etc/rc.tcpip, and to start xntpd:
<cli prompt='#'>
# chrctcp -S -a xntpd 
</cli>

To disable xntpd in /etc/rc.tcpip, and to stop xntpd:
<cli prompt='#'>
# chrctcp -S -d xntpd 
</cli>

To enable xntpd in /etc/rc.tcpip, but not start xntpd:
<cli prompt='#'>
# chrctcp -a xntpd 
</cli>

To disable xntpd in /etc/rc.tcpip, but to not stop xntpd:
<cli prompt='#'>
# chrctcp -d xntpd 
</cli>

For info, since AIX 7.2 TL4 **sendmail** need to be started, as it's required to send email

Sendmail process is starting using
<cli prompt='#'>
# startsrc -s sendmail -a "-bd -q30m" 
</cli>
