FreeSSHd for Home windows, arrange an SSH and SFTP server simply

The set up wizard will ask us if we wish to create the non-public keys

The set up wizard will ask us if we wish to create the non-public keys for the SSH, click on on “Sure” to create them robotically and with out having to do anything. It’s going to additionally ask us if we wish to use this program as a system service, we click on on “Sure” in order that it begins with the working system, in any other case, we are able to click on on “No”.

As you possibly can see, downloading and putting in this program is actually easy. Now we’re going to see all of the configuration choices that we have now obtainable on this full program.

Configuration choices

Within the first menu of FreeSSDd we’re going to discover the state of the SSH and Telnet server, by default, the Telnet protocol is deactivated for safety causes, and we don’t advocate activating it beneath any circumstances, you all the time have to make use of SSH as a result of all visitors it’s appropriately encrypted and authenticated.

Within the tab of «telnet» We will configure the place we wish the Telnet server to pay attention, the TCP port used, the utmost variety of concurrent connections, the timeout in case no instructions are despatched, and in addition if we wish to put a welcome message. Lastly, we have now the chance to decide on the shell, by default it’s cmd.exe however we are able to additionally select Powershell, as well as, we are able to allow Telnet firstly of this system.

Within the tab of «SSH» is the place we have now the whole lot associated to the SSH protocol, we are able to make the next configurations:

  • listening route: by default it’s listening on all bodily and digital community interfaces, right here we are able to select that it solely listens on a sure interface.
  • Port: by default the port is TCP 22, however we are able to change it to the port we wish.
  • Most variety of connections: if we depart it at 0 it means limitless variety of connections.
  • idle timeout: the time the server waits till the connection is lower if we don’t change knowledge, by default it’s limitless (0).
  • banner message: we are able to put a message for the SSH purchasers that hook up with the server.
  • Command Shell: command console to make use of, by default it’s cmd.exe though we are able to additionally use Powershell. Different choices are to begin the SSH server after we begin freeSSHd.
  • keys: we are able to configure new cryptographic keys, be they RSA, DSA and in addition ECDSA if we wish. Essentially the most advisable is to make use of the ECDSA keys which might be the most secure and quickest.

Within the tab of «authentication» we have now the placement of the general public cryptographic keys that will probably be exchanged with the purchasers, we even have the chance to configure password-based authentication (disabled, allowed or required), as well as, we even have the chance to configure public key authentication. In “encryption» we have now the totally different ciphers that we enable for SSH purchasers, the most secure factor is to make use of AES in any of its variations, we don’t advocate utilizing the remainder of the symmetric encryption algorithms, as a result of they’re insecure or not safe sufficient for one thing as essential as SSH protocol. Within the part of “tunneling» We’ve the potential for enabling native port forwarding and in addition distant port forwarding, it will enable us to make SSH tunnels, which is sort of a sort of VPN however utilizing the SSH protocol as a substitute of a digital non-public community comparable to OpenVPN or Wireguard. Within the “SFTP” menu is the place we have now the trail of the folder that can seem when connecting with any SFTP shopper comparable to FileZilla.

Consumer administration is likely one of the most essential elements, on this case, within the «customers» is the place we are able to add, change or delete the totally different customers that we have now. When including a brand new person, we have now to enter the title, the kind of authorization (NT authentication, password or public key for SSH solely). We will additionally configure if we wish the person to make use of the shell, use SFTP or Tunneling. Shell and SFTP permissions ought to usually be given, though optionally you may as well do SSH tunnels.

Within the tab of «logging» We’ve the power to configure the logs of the freeSSHd program, and we are able to even resolve IP addresses to hostnames to make it simpler to learn the logs. Within the menu of «On-line customers» we have now the chance to see in actual time which person or customers are presently related to this system’s SSH server.

Now that we have now seen all of the configuration choices of this system, and we have now created a person to attach domestically or remotely to our pc with the SSH server, we’re going to present you the way to join with the favored PuTTY program.

SSH and SFTP connection

PuTTY is likely one of the hottest and used packages for SSH shopper, Telnet shopper and even to connect with a router or change by console. In our case, we have now entered the non-public IP deal with of the pc the place we have now configured freeSSHd as a system service, we have now additionally entered the port quantity, 22, the default port.

When connecting, it would point out that we should settle for the general public key, and that the secret is not acknowledged as a result of we have now by no means related, so we have to be cautious when accepting the important thing. As soon as accepted, we proceed to enter the username and password that we have now beforehand registered in this system, as soon as we join, we can see the terminal (cmd.exe) by way of SSH in our PuTTY shopper.

The method to attach by way of SFTP is analogous, on this case we are able to use a program like WinSCP that helps the SCP and SFTP protocol, or use the favored FileZilla Shopper program that additionally helps SFTP. On this case, we enter the sftp://IP deal with, we put the username and password that we have now beforehand created, the port quantity 22 and click on on «Fast connection». As soon as we have now related, we are able to see the listing tree and proceed with the copy of the recordsdata.

As you will have seen, the connection of an SSH and SFTP shopper to the server configured with FreeSSHd could be very simple and quick, we are going to solely have to configure sure parameters on the server in order that the purchasers join simply and with out issues.
