How to Set up an SSH Server on a Home Computer

Zach Duey on August 27, 2017

Around 18 months ago, I built a desktop computer so I would have a little more firepower at my fingertips when I needed it. My hope was to avoid ...

Hey! I am a noob at all these things. When I do ifconfig it shows eno1 not eth0. Are those same? Because I am using Ubuntu 16.04. And nothing shows when I do ifconfig | grep "inet addr". And When I ifconfig | grep inet, then some IP address shows up when I try to ssh using a different machine from the different network. It shows me "error :ssh_exchange_identification: read: Connection reset by peer". Can you tell what I am doing wrong?

I don't know but here are 2 tips:

Use ip not ifconfig, see how and why

Use ssh -vvv verbose mode which will tell you more details why it failed.

Eth0 was an old convention and is used when the OS can't determine where the card is.

Eno refers to an interface on the motherboard, with the # representing which interface (for servers with more than 1) there's another set of letters to identify expansion card interfaces, but it's a google search away

This new convention is more in line with how Linux names their storage devices ie: sda, vdb, etc..

Great work, all i needed to do was the openssh-server package, the sshclient is provided with GitBash for windows, which is probably installed. but i guess iwould have to port forward to do this anywhere else, my use case is just windows machine to my linux machine

Hi, thanks a lot for your guide! It has been very insightful and useful.

Unfortunately, I encountered a problem I did not expect, and I do not know how to fix this.

For a few days after I configured my devices everything ran smoothly. Nevertheless, all of a sudden, I could not log in my home computer anymore and I found out that the public IP address of my home network changed.

Do you have any idea how this could happen? I may have rebooted my router one time, but I did not know that at every reboot the IP address changes. How can I keep it the same?

Thanks a lot!

Best,

T

My broadband provider has provided me with private IP. I checked my IP at whatsmyip.org, which is different from the IP showing at my details WAN. Do I have to buy a public IP from them or I can buy that from anyone else?

yo wtfismyip.com is way better alternative

IP getting

Some options

ifconfig.io
ip.envs.net
ifconfig.me
whatsmyip.org In the oder hand you cloud opt to use a DDNS

DDNS ( Dynamic Domain Name Service )

A popular example is Duckdns, or FreeDNS, these services let your server make a request and get one of their subdomains point to you instead of using an IP address

Very well written i learned a lot from this however i am stuck with weird issue i was attempting to log in from different network but i am getting permission denied error any idea what is causing this because i can log in from the same network

sudo restart(or stop or start) ssh

doesn't work anymore on recent ubuntu OS (16.04 and above). To start your ssh server you need to use:

sudo systemctl start ssh.

Hey brother! Can you tell something about eth0 and eno1? Can read you my comment above or below and help me?

Pawan Kumar • Jun 24 '19

Nice one, btw the ifconfig doesn't work for me, ip is the alternative.

Thanks Zach. I can now access two small servers on my private local network from anywhere I have Internet access. I connect to my desktop and ssh from there to the other machines. Next I plan on bumping up the security as you discuss in the last section.
