Disabling Telnet

[Bob Ferro]

I added an entry in /var/adm/inetd.sec in one server as follows:

telnet allow 166.20.244.127 spdtech

I am able to telnet to this server and no one else can. I added an entry in /var/adm/inetd.sec in another server as follows:

telnet allow 166.20.244.127 spdtest

I am not able to login in. What did I miss?

P.S. I have a static ip.

First make sure you can access the server across the network (ping). Maybe the server is on a different subnet or something.
Also compare the files /etc/inetd.conf on both servers. You should have a telnet entry in there.

Attaching an example inetd.sec file that might help.

Pls run inetd -c and try again.

telnet can only be disabled in two places:

/etc/inetd.conf (disables telnet completely)
/var/adm/inetd.sec (disables subnets and actual ip addresses)

After making changes to /var/adm/inetd.sec does not need to have an inetd -c run after. This is only for /etc/inetd.conf

Hi Bob,

Please check this link:

Login thr' console on another server and check following:

# telnet 127.0.0.1

This should give you a login prompt.
This will confirm whether telnet itself is working properly on your another server.

In case if it work, then you need to check inetd.sec file for any errors.

Thanks to everyone for all the help. I have one more problem. Some users need to telnet into the system via dialup. Some internal users need to telnet (no static ip for these guys). My question is there anyway to allow users other than using the ip address? Say by user name?
