Ubuntu – How to install openssh from usb

openssh

Hi I have installed ubuntu from bootable usb. During installation I did not pay attention for Openssh server in software selection screen. however is it possible to reboot from usb to just install openssh only without affecting anything which is already installed and configured? Just like we install feature/server role in windows!!! Thanks. I dont have internet connection in my server yet. thanks.

Rather, you can download the .deb file on any other machine which is connected to the Internet. Using the following command:

sudo apt-get install download openssh-server

The, install the .deb image on the server using the following command:

sudo dpkg -i /home/himanshu_code/Desktop/ssh.deb

So your machineG (the fresh install) is the one with issues:

Check sshd if it's up sudo service ssh status.
Check Name resolution. The name of your machine, check it if is the same on /etc/hostname, and /etc/hosts.
Check firewall. sudo service ufw status maybe is best if you install firewall of ubuntu Gufw.

hi! did you solve it? @philipballew asked you to see if you have port 22 enable.. do this on the 2 machines netstat -nat | grep 22: you will see something like this:

~> netstat -nat | grep 22
tcp        0      0 0.0.0.0:22              0.0.0.0:*               LISTEN      
tcp        0      0 10.202.10.13:53414      173.194.76.125:5222     ESTABLISHED 
tcp        0      0 10.202.10.13:50912      10.100.202.21:22        TIME_WAIT   
tcp        0      0 :::22                   :::*                    LISTEN

If one of the ports 22 are not listen then re-check all that I previous told you. Actually I'm a bit lots with the names of the machines. You call them in differents names all the time....
