If you want to telnet to work, you need the telnet server running on your work computer. To use the telnet client, you do not neet to install the telnet server component.
If you are going to connect to work over the net, you are strongly recommended to use ssh. If your problem is some windows clients wanting to connect to the Linux server, you can download and use Putty which is a free ssh client.
Originally posted by blackzone Probably a stupid question.
For cisco routers and other firmware they usually use telnet right?
if ssh is so much more secure why use telnet instead of ssh?
'cause they are stupid and also 'cause windows does not come with a ssh client.
I would suggest having ur cisco router behind a firewall and using ssh to go access the firewall and then telnet to access the router.
thats how it is at my workplace and this method is highly secure.
well, there is a list of services that you can turn on and off...start X and in a console type: system-config-services and u'll open up the config program, u can check or uncheck telnet and then save your settings,
but if you can't find telnet in that list then, i guess u'll just need to find it in your install cd's, runno which rpm that would be tho..
I am not sure, but if you do not enable the telnet server, but use the telnet command in the shell, could you connect to the cisco router? I also believe that you can disable telnet on the router for the network interface and connect directly to the serial interface instead.
In the very least, disable the telnet service on your computer after using it.
You don't have to have the telnet service running on your machine to be able to telnet TO other machines. Running the telnet service allows users on other computers to telnet onto your machine.

Rep:
Most versions of Cisco produts have SSH in addition to telnet, it's just that most admins are lazy and most use Windows, which does not come with an SSH client by default (PuTTY is so easy to download, so that's no excuse). Also, interestingly enough Cisco has pretty much matched bug for bug with OpenSSH, so despite their supposed laothing of Open Source, it looks pretty convincing that they actually use it (secretly).
As mentioned, you do not need to run the telnet service in order to use the telnet client.
