Hi,

When i check csf (check server security), i get this ntice:
Check telnet port 23 is not in use

I have removed telnet by

Code: Select all

yum remove telnet

and port 23 is in block list.

what should i do to find out why this notice has been appeared ?

by the way, I'm using centos 7 and directadmin and there are update.

for who's that is a warning in csf, after removing telnet and blocking port 23, you should reboot the server and the warning will be disappear.
