disable telnet

[Angela Swyers_1]

I want to force my users to use Secure Shell to log into my server. How do I do this? Do I just stop the telnet daemon, or is there a better way?

[Wilfred Chau_1]

yeah. Disable that in inetd.conf

[Joseph Loo · Accepted solution]

hi,

stopping telnet daemon is an option. u may do in /etc/inetd.conf:

# vi /etc/inetd.conf
-> comment off telnet line
# inetd -c

Also, u may like to do something about the assignment of points, 10 out of 156 shows a lack of appreciation to those who have help answer your queries.

regards.

Hi

Just rem this line in the /etc/inetd.conf:

telnet stream tcp nowait root /usr/lbin/telnetd telnetd

Then do:
#inetd -c

there is a file /etc/services

if you vi this and # out any service you do not wish to run ie telnet is here and other services.

[lawrenzo]

hate to be the points police but you may have got a better response if you did assign points.

Thanks

[Nguyen Anh Tien]

pls do these step:
#vi /etc/services
#rem telnet service
#telnet 23/tcp # Virtual Terminal Protocol
SAVE AND EXIT BY ISSUE:wq!
Reconfig inetd service
#inetd -c
That all
HTH

We can do by commenting telnetd in /etc/inetd.conf file. And also comment telnet service in /etc/service file. Then restart inetd daemon as inetd -c.

You can also use /etc/profile file as,

ps|grep -q 'telnet'
if [[ $? -eq 0 ]]
then
echo "Plz use secure shell for usage"
sleep 2
exit 1
fi

It will also work.

HTH.

You can also change telnet allow in telnet deny in the /var/adm/inetd.sec.
