I think this type of questions were answered before but due to lack of networking knowledge, for a couple of years I searched the internet and read many websites in an attempt to connect to an SSH server over the internet. But I have failed. I want to know if it is possible to connect two systems using SSH without using third party services like ngrok.
I have two computers running ArchLinux.
Computer A and B are inside a local network but I want to set up the ssh so that I can access A from B via SSH over the internet (like how Anydesk, Teamviewer and other such remote desktop software connects).
Systems Details:
1. The systems are connected to a [Digisol] router.
2. Both have package installed. System A is running . A can get connected to B over the LAN.
Hostname of system A: archlinux-pc
Hostname of system B: archlinux
On both the systems the username is sourav. That is, I want to connect to sourav on archlinux-pc.
Set up Virtual Server configuration on the router (Digisol):
My public IP is xx.xxx.171.113 as reported by ident.me. The IP doesn’t change in a period of many months.
whatismyipaddress.com shows the same IPv4 but IPv6: Not detected
My router has a section called WAN Configuration which shows some different IP:
I have already tried using from system B, which takes a long time but doesn’t connect at all.
I have also tried these links:
https://raspberrypi.stackexchange.com/questions/13861/setting-up-ssh-over-internet-on-my-pi
https://help.ubuntu.com/community/SSH/OpenSSH/PortForwarding
How do I get connected to system A from system B using SSH without any other services like ngrok if something like that is possible? Also, can I connect to system A over SSH using termux running on my Android phone?
