I have trouble connecting to a server with ssh from my Lubuntu 14.04 computer, although it can be done from other machines. I can't get to the address online either (others can).
Am currently using a 3G network from my phone, but this doesn't seem to be the problem as I can connect to the server using another computer with the same 3G connection.
This is my attempt to connect:
root@Elizabeth:/# ssh USER@HOSTNAME
ssh: connect to host HOSTNAME port 22: Connection timed outUPDATE: Saw that ping HOSTNAME renders the wrong IP-address, so I guess this could be a clue to what's wrong. Any way to solve that? I can get around it though by doing ssh USER@IPADDRESS, as suggested to me in a comment.
Some further info below, if it's useful. I'm new to working with servers and networking, so do say if there is other information needed to say what is wrong.
root@Elizabeth:/# nm-tool | grep "DNS"
DNS: 172.20.10.1
DNS: 172.20.10.1
root@Elizabeth:/# nslookup HOSTNAME
Server: 127.0.1.1
Address: 127.0.1.1#53
Non-authoritative answer:
Name: HOSTNAME
Address: IP-address # correct IP-address for HOSTNAME
root@Elizabeth:/# ip route

To properly test your ssh use ssh user@ipaddress. If that fails, the issue is something deeper like the connection.
Allow ssh to ufw will solve the problem. Run the below command to allow.
sudo ufw allow sshTo properly test your ssh use ssh user@ipaddress. If that fails, the issue is something like the firewall.
For example, checkout firewall status with below code
sudo ufw statusIf it is working then first deactivate firewall with below code:
sudo ufw disableand test ssh user@ipaddress
Allow ssh and port 22 from ufw, then enable it and check with status command
sudo ufw allow ssh
sudo ufw allow 22
sudo ufw enable
sudo ufw statusplease go to the Network setting, choose the Ethernet connection and disable all Ethernet connection only connect to the Wi-fi. after that go to your terminal and write ssh username@ipaddress (ssh stackoverflow@161.10.10.1)
