Opening Ports


I am having connection issues with my new box. When I use IE, I can get the apache test page no problem. When I try and telnet in, port 23 is tried and the connection is failed. My only conclusion is that the http protocol goes through but something isn't configured correctly to allow the telnet connection to go through. Can anyone help with this?

Hi George!

Since telnet doesn't use encrypted passwords
when going over the wire it's rightfully considered
a security hole and disabled by default...

You might want to try using ssh instead.

If you insist on telnet you'll have to edit
your xinetd's configuration ... man xinetd
to find it's name/location, haven't touched
RedHat in ages

Cheers,
Tink

Tinkster's right. You might want to check your inetd.conf file also which has all your services that are available to run. Make sure that your telnet service isn't commented out (doesn't have a # at the beginning of the line). I don't know where your inetd.conf is located as I don't use RedHat, but you can do a "whereis inetd.conf" or "locate inetd.conf" and that might produce better results for you. Another one to check is /etc/services which will list all your ports and the services connected to them (telnet is typically port 23). Make sure that the port isn't commented out there as well.

I do, however, have to agree with Tinkster in that you should probably look into ssh instead of telnet, but it's your system so you can do what you want. Hope this helps.

FYI: Redhat doesnt use the older inetd but the newer xinetd.
u should check in /etc/xinetd.d the telnet file. (vi /etc/xinetd.d/telnet)
see if it isnt set to "disable = yes"

Look here ... ssh is a secure shell,
you just type ssh <host> instead of telnet <host>,
and yes, it will allow a remote root login. :)

Cheers,
Tink
