Q. I have just installed Ubuntu 6.06 and I would like to allow remote login to my system from home via ssh. How do I install and configure SSH server?
A. OpenSSH is a FREE version of the SSH connectivity tools that technical users of the Internet rely on. Users of telnet, rlogin, and ftp may not realize that their password is transmitted across the Internet unencrypted, but it is. OpenSSH encrypts all traffic (including passwords) to effectively eliminate eavesdropping, connection hijacking, and other attacks. Additionally, OpenSSH provides secure tunneling capabilities and several authentication methods, and supports all SSH protocol versions.
Ubuntu SSHD Installation
Type the following two command to install both ssh client and server:
# sudo apt-get install openssh-server openssh-client
SSHD Configuration
To be frank your server is ready by default. Just test it from your home computer or from same system with the command:
# ssh localhost
OR
# ssh user@your-server-ip-address
How do I use ssh client?
Assuming that your server hostname is userver.mydomain.com and username is vivek, you need to type the following command:
# ssh vivek@userver.mydomain.com
To stop ssh server, enter:
# sudo /etc/init.d/ssh stop
To start sshs server, enter:
# sudo /etc/init.d/ssh start
To restart ssh server, enter:
# sudo /etc/init.d/ssh restart

Thanks a lot – this is very helpful
where can I find my ip address, I use the wireless network provided to me by my college.
when I do
“ifconfig”
I get
eth1 inet addr:10.XXX.XXX.XXX
and
lo inet addr:XXX.XXX.XXX.XXX
now from remote, when I try
ssh @10.XXX.XXX.XXX
its refuse to except my password.
also, from the other blog, i edited /etc/ssh/sshd_config file and I added line
AllowUsers
but its still not working. which IP address I am suppose to use.
also, when I open a website, which gives IP address, it shows my IP address as
127.XXX.XXX.XXX
which is different from 10.XXX.XXX.XXX which i get using “ifconfig”
Thanks
Great! Thanks for the info, i need to update my sourcelist to begin with the installation.
Devvrath: Use your external ip, not the local ip, if both you and the server is localy, you can connect to the lokalip of the server, if your not local, use the external ip,
thanks for the quality information

Hi,
My system is isolated from the Internet. How do I get and install OpenSSH in this env?
Thanks,
Gang
Hey all, I can’t seem to get my SSH to let other people connect. It works fine for any local computer on the network but if you try connecting VIA the internet it has connection errors. Does anyone know why? I was told my tunneling needs to be set so i just set tunneling to YES and it still doesn’t work…
Thanks alot! Mikey
I have the same problem as Mikey. Anyone have a solution?
@ Dennis
Open port using Firewall. You need to setup port forwarding if you are using DSL/ADSL/Cable internet.
Thanks a lot! It’s a great tutorial!
Gentjan
for home user that’s using DSL/ADSL/similar router, make sure that the port is forwarded to your machine.
for other version that cant run, not sure if this will work:
sudo apt-get update
possibly the record in your ubuntu is not updated yet…
This is really great.
Very helpful for me.
Thank you very much.

hi i am testing SSH on linux and i am having problem connecting to the Linux SERVER. i have a client PC running Putty (shh) and a Linux SSH server (bear box modem). when i try to connect to the SSH server via a PC running Putty connected to my 3G modem i get network error: timeout. Linux box is also connected to a 3G rooter with port 22 forwarded.
when i connect to a PC loaded with Unix or Windows running and loaded with SSH server, i can connet fine with no hassle. using the same setup
can you please help
Why not use a utility service with ‘ # sudo service ssh start’ which is more better than initiating init script from a folder with # sudo /etc/init.d/ssh start?
