telnet server?

[jjd228]

is there a telnet server installed by default that i can start? or do i have to install one seperately?

[threadhead]

in general there is one installed.

take a look at your /etc/inetd.conf file.
watch out for a line looking like this

#Telnet server
#telnet stream tcp .....

uncomment the second line and reboot.
telnet server should be running.

Yes, it's called ssh - Depending on your distro you may be able to start it with one of the following commands:

/etc/init.d/ssh start
/etc/init.d/sshd start
/etc/rc.d/init.d/sshd start

Of something very similar.

Don't bother using telnet when you can use ssh.

great, thank you. so whats the difference between ssh and telnet? i assume theyll both accept terminal connections on port 23? and im using redhat 9, so what would my path be?

ssh uses port 22 by default. Read the home page here for more info:

Never, ever use telnet for anything.

Always use SSH.

telnet sends password in clear text, whereas SSH is encrypted.

And you should use ssh 2, I believe ver. 1 isnt secure enough.

You shouldn't need anything. You will just need to "ssh ip/host". Ie: ssh localhost

Oh, and btw...if you want to connect from a Windows box I'd suggest you to get PuTTY (http://www.chiark.greenend.org.uk/~sgtatham/putty/), it's a telnet/ssh client.

What distro? Mabye it's using xinetd.conf

[mrbl0nde]

try /etc/xinetd.d/telnet, obviously for telnet.

sshd is different. it should be installed as a daemon in /etc/init.d/sshd. if it's there, initiate it by the following:

# /etc/init.d/sshd start

you can control access to the ssh server via the /etc/hosts.allow and /etc/hosts.deny file.

Odds are in regards to you not having inetd.conf installed is because you have not installed inetd (not being sarcastic). I don't use RedHat, but you should be able to issue a querey using rpm (rpm -q I think it was...it's been years). If you don't have it installed, it is easy enough to fix. Just install the rpm off your CD or download it. On my system I just go:

whereis inetd

And the path to all files inetd is listed.

Redhat has been using xinetd instead since v7.
The file would be in /etc/xinetd.d and called telnet.
You'd need to set
disable=no
in the file and then restart xinetd eg
service xinetd restart.

HOWEVER, I strongly recommend you with SSH as above. Its encrypted (inc usrname/passwd).
Telnet isn't.
SSH is a standalone daemon eg like Apache/httpd, so is not managed from xinetd.
Usually started during boot sequence.

HTH

[jjd228]

thank you everyone. but this telnet server is strictly for internal use. security isnt a concern

Hehehehe. That will teach me. I haven't used Redhat since 6.0.
