How to Disable Telnet on AIX 6.1

Edit and comment out telnet . As an example it will looks like

lpar2#vi /etc/inetd.conf  

 #telnet  stream  tcp6    nowait  root    /usr/sbin/telnetd      telnetd -a

Now Refresh the inetd daemons

# refresh -s inetd
You should get an error message like this:

lpar1 #telnet lpar2
Trying...
telnet: connect: A remote host refused an attempted connect operation.
lpar1 #

 Done…
