SSH, or telnet? What do I need?

TheWart · Posted: Mon May 13, 2002 4:08 am Post subject: SSH, or telnet? What do I need?

Okay, I just installed Gentoo on my old p200, (about 17 hours IIRC), this is for a gameserver for a ~10-12 person Lan party I am going to when school is done. However, I also did it just for my home network, which consists of this box and two other comps. However, since I only have two keyboards and mice and monitors, it is going to be a pain for me to hook in a monitor and stuff every time i want to change a mpa or something. So I was like, well can't I just telnet into the box and run commands from windows? However, to be honest, I have no idea how to do this. Would I use telnet or ssh?

I would appreciate any and all guidance, and links to what I need to do/get would be GREATLY appreciated. Thanks in advance!

ssh is the choice nowadays, its more secure and has more features than telnet. To intall on your gentoo box just type
emerge openssh
and then
rc-update add sshd default
then
/etc/init.d/sshd start

you can use putty availiable at
http://www.chiark.greenend.org.uk/~sgtatham/putty/
it is an excellent free ssh client for windows

one thing to beware of is that base windoze systems only include a telnet client and so cannot use an ssh server. so if you do go with the ssh server (which you should) make sure to grab a prog like putty which is able to handle ssh connections.

When you set up sshd for the first time it will you ask for generating a keypair. Type the following:

Thanks for all the info guys. I will be using PuTTY to connect from windows.

unless recently changed, there is no need to manually run the commands to generate keypairs. once ssh is emerged (actually its emerged on install isn't it?) , just do as root

As someone above posted, PuTTY is a great client to connect with just about any protocol (ssh, telnet, raw, scp, ...), and fits nicely on a floppy disk.

SSH is definitly the way to go.

Thanks guys, it worked!!!!

I did not have to emerge it, as it already was, but I DID have to create the keys. I also had to change the port as I had to work around my router/firewall. Other than that, it is pretty nifty, I must say. I need to take Putty to school and control my comp from home, it would impress the gals

Just a side not, the sshd init script (/etc/init.d/sshd) will automatically generate your ssh keys upon first run. Note the gen_keys function:

Doh! O well, it didnt take but a few seconds to do the keys anyway. Overall, it was a lot easier than I had expected after so many people said they couldnt get ssh working.

I think that should be:

rc-update add sshd default

Sorry guys but, if i undrestand, the forum initator needs only conect from his LAN to his "server", so isn't necessary use a cryptographic connection because the channel is secure.
Otherwise if he needs to connect from outside his LAN then is necessary a ssh connection.

while that is True, I wouldn't want to run a Telnet server on the system, its just another hole for potential attacks. your network is only as secure as its weakest opening, and theres no need to run a telnet server when SSH is 1000% more secure.

Yes you need ssh instead. No excuse to run telnet for any reason on any server. Port scanning at LAN parties can be fun, as can packetsniffing if you can get on a hub between a few computers.

At the same time, a firewall is a Good Thing too - yes, even at a LAN party.

One other thing you will definately want is screen - lets you reconnect, etc. to the server process running. Its a Quake* admin's little helper.

It's a command line ssh / sftp / scp client for windows. It's nice because it's the exact same tool you use under gentoo ported to windows. Plus you can run an SSH server. Nice. I use this tool a lot.

Not sure if this has been covered as of yet but I think changing sshd_config to dissalow root logins is a good idea..

you can use telnet if your crazy and in a secured, isolated enviroment, but even in such i am paranoid enough to still use ssh
