Hello all. I was wondering what are the steps that I need to take to make it so that my friend can ssh into my machine from a remote location. I have absolutely no experience in setting something like this up, just curioius to see if someone could guide me through it. Thanks.

You need to give him a user account (shell) and start the ssh daemon, which is already started by default in Slackware. Go through the normal 'adduser' process, and assign him a login and password. Give him that info.

If your machine has a direct connection to the net, you can give him your ip address and he should be able to 'ssh name@ip.address.example'. If you're behind a router, you need to set up port forwarding to your internal IP address.

First, You need to make sure that you have an installed ssh server.

Command:
rpm -qa | grep ssh

openssh-3.9p1-8.0.1
openssh-server-3.9p1-8.0.1 ----- you should have this
openssh-askpass-3.9p1-8.0.1
openssh-askpass-gnome-3.9p1-8.0.1
openssh-clients-3.9p1-8.0.1 ---- you should have this also

Second you need to make sure that your ssh daemon is started before your friend can connect to your machine.
Command:
ps -ef | grep sshd
root 3349 1 0 01:53 ? 00:00:00 /usr/sbin/sshd --- you need to see this running

Third you have to determine if your firewall is allowing port 22 connection from outside your network. This scenario is only applicable if you have a public IP and your friends also, but if your only trying to connect tru your LAN you can ask your friend to telnet your IP address port 22.


Your friend's command.

If you are done and successfull with the steps above, you have to create a user account for your friend which he will be using if he is now trying to connect to your machine.

Command to connect to your machine:
---------------
ssh (your ip address) -l (user name you created)
---------------
ssh 192.168.1.1 -l mike

Thats it...

Mike

He's running slackware the rpm -qa command won't be appropriate for him.

If you did a full install, onelung, sshd will already be installed and running.

OHHHHHHHHHHHHHHHH....URGHHHHHHHHHHH... SOrry man...

Ok, the slackware way.

To check if it is installed

ls /var/log/packages | grep ssh

To check if it is running.

2 ways

ps aux | grep ssh
or
nmap localhost | grep ssh

And also read the other posts regarding how to add a user and how to connect

ls /var/log/packages/* | grep sshd ( don't forget the /* )
and the server is called sshd ( deamon )

...just to be complete...

egag

You don't need the /* after packages

nukey@box:/$ ls /var/log/packages | grep ssh
openssh-4.0p1-i486-1


And your right, the service is called sshd, but when you do a "ps aux | grep ssh" only the sshd will show up (unless you're ssh-ing to another machine at that moment)

my bad....

i meant smth. diff.

grep sshd /var/log/packages/*

you are checking on package-names and the above checks on filenames.
( that's what i use... )

....and the d was just to be complete....
( but i was just complete wrong... )

egag

Glad that's all sorted out

I just really like that /var/log/package directory the easiest way (maybe not the best) to see what's installed on your system.

as soon as I get situated I am going to try this out, thanks for the flood of replies!!!!! I will let you know how it goes. Unil then...

argh. with the redhat people.. always giving useless advice.

ssh is the easiest thing I've ever dealt with in linux. I've never had to reconfigure it or anything.

if it's installed and /etc/rc.d/rc.sshd is set as executable it'll run at boot.

Indeed, very easy.

However, there are 2 things i like to configure:

open /etc/ssh/sshd_config

Protocol 2 (so it only accepts ssh protocol 2 attempts)
AllowUsers nukey (for example) (here you can define witch users may login)
PermitRootLogin no (so no-one is able to directly ssh to my box as root, maybe it's not that big issue but i like to keep it tight )

You should modify /etc/ssh/sshd_config and set PermitRootLogin to no. This will protect you from people who try to break in to your box. If you need root just login with your standard login and then use the su command to change to root.

Maybe this is of some use:
