08 - How to Connect to Servers Remotely by SSH? Using Putty and Mobaxterm
Hello everyone,
In this video, we learn how to establish an SSH connection to a remote server. The servers we work on are typically located in remote server rooms or in the cloud. Therefore, we can't access them directly by going to them. We work remotely.
Since most of the servers we work on are Linux-based, our connection method is 99% likely to be SSH.
In this video, we go through the client and server setup necessary for an SSH connection. We install Putty and Mobaxterm, the most popular SSH client tools, on our computer. We also install the openssh-server package to enable SSH on the server side.
Then, we connect to the virtual machine on our computer as if it were a remote server.
We also demonstrated how to list a server's network interfaces using the ifconfig command, how to find a server's IP address, and how to install openssh-server.

Note 1: If you're connecting to a virtual machine you've installed on your own computer, as shown in the video, make sure the virtual machine's network settings are set to "Bridge." You can remotely connect to the IP address it receives as Bridge from your Windows machine or from other computers connected to the same modem. If it's set to NAT, you won't be able to access it.
Note 2: If you selected Bridge Adapter instead of NAT in the Adapters section and it doesn't work, you may be experiencing a firewall-related issue. To resolve this, on the Windows host device, go to Settings / Update & Security / Windows Security / Firewall & Network Protection / Disable Windows Defender Firewall (if you're also using an external security application). Then, restart the device and try again.
Enjoy! 😊
