Note: Though your putty screen might look a little different than the one seen here due to version differences, the basic steps would be still the sameĢ) In putty, on the left-hand navigation panel, open SSH option and select “Tunnels”. Port 22 will be selected which can be left alone unless you run the SSH service on a different port. Note: If on the remote network’s subnet is same as your home network’s subnet then you might run into IP conflicts.ġ) On the remote system, open putty enter the IP address or dynamic DNS (DDNS) name in the host name field. You can make any number of connections to all your home machines by just repeating steps (3) and (4).Since we are using a proxy it will resolve the local subnet’s IP address properly. SSH connect to any machine at home using the local subnet IP address.Open another putty session and configure it use the previous putty session as proxy.From this session connect to your default SSH server at home.Open a putty session and configure it to act as a tunnel.Then using this connection as a tunnel we can connect to any machines at home by addressing them with local sub-network address (such as .x). The basic idea to get this working is that we make one initial SSH connection to our home machine. On the router, port forwarding is enabled for SSH service to at least one of these machines.One/more Linux/Windows machine(s) to which direct SSH access is required.Home router’s internet accessible IP address or dynamic DNS (DDNS) address.Remote machine with Putty installed in it.But now I found a cooler way to get SSH access to all my machines at home without setting up port forwarding or remembering any port numbers and most importantly, I can address my home machines with local subnet IP address, no matter wherever I connect from the internet. It was also difficult to remember port number forwarded for a particular machine. It was a tedious process of enabling port forwarding and then disabling it after use. Previously, when I needed SSH access to these machines I used to setup port forwarding on my router to each of these machines. I have multiple Linux machines at my home. If you have any questions or ideas, please leave them in the comments section below.Create your own Virtual Private Network for SSH with Putty We hope this article has helped you change your SSH port on VPS. Then, restart the SSH service and test the new port’s connection again. Hence, it is best to use a port ranging from 1024 to 65535.Ĭonfiguring a new specified port is relatively easy – you only need to update the number in the SSH daemon configuration file and firewall settings. Therefore, we recommend changing the SSH port to avoid potential cyber attacks and add extra protection to your Linux server.īefore choosing a new port for your SSH access, note that the ports numbered 0-1023 are reserved for privileged services. Using the default SSH port 22 can make you an easy target for hackers – they often look for open ports through which to intercept and extract sensitive data. Do not log out from the previous root session until you’ve confirmed that the new setup is working well.Īs for Hostinger users, if you cannot connect to your VPS using the new port, you can always reset the SSH and firewall settings to default from your VPS dashboard on hPanel. Test the SSH connection using a new Terminal window. Next, delete the number and # and replace it with the new SSH port number you want to use. Start by executing the following command to access the SSH daemon (sshd): sudo nano /etc/ssh/sshd_config Once you’ve done so, the connection will be established. To do so, run the following command line on Terminal or PuTTy: ssh example: ssh you will be prompted to type the password or SSH keys. In this section, we will explain how to change your default SSH port in four simple and easy steps. Therefore, we recommend choosing from different ports ranging from 1024 to 65535 as they are non-privileged. Lightweight Directory Access Protocol (LDAP)Īlthough you can still use them, doing so will put your SSH connection at risk of network conflict. Simple Network Management Protocol (SNMP) Here is a list of the most common privileged services and their associated ports and functions: Portĭynamic Host Configuration Protocol (DHCP) When choosing a new SSH port, note that port numbers 0-1023 are reserved for various services and can only be bound by root access.
