+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>
