Changing SSH Port for Increased Security

SSH Port

Changing SSH port is a great way to increase your security. This can be useful when you have thousands of bots scanning the Internet for open SSH servers. Changing the port to something obscure will make it harder for attackers to gain access to your server. If you’re running a Linux server, this can be an especially effective security measure. If you’re running a VPS, you can use Advanced settings to configure multiple ports.

Disadvantages of ssh change port

While it is true that changing your SSH port can increase your security, it also brings some disadvantages. The default port for SSH is port 22, making it easier for an unauthorized person to get to your server. If you change the port to something else, the attacker will have to try different ports before they find the one that’s open. The disadvantages of changing your default port may not apply to your situation.

One of the biggest drawbacks of port forwarding is security. By default, your SSHd daemon listens on TCP port 22, and changing it to another one reduces the vulnerability of your server to automated network scanning. You should also make sure that you install a personal firewall on your PC if you are using this method, since your PC is directly connected to the internet. This can help prevent unauthorized connections.

Changing the default SSH port on Linux

Changing the default SSH port on Linux is easy, and most distributions come with a configuration file. Once you have found this file, you’ll need to edit it to allow the new port. This file can be found at /etc/ssh/sshd_config. For different Linux distributions, this file may have different names, but the process is the same. Just be sure to change the name of the file to the new port.

Firstly, open Terminal (Ctrl+Alt+T), or VNC, and then type the command. After entering the command, make sure that there is no # before the Port. Press Ctrl+O to save the changes and Ctrl+X to exit the editor. Finally, configure your firewall to allow connections from the new port. Some distros use different default firewalls, so be sure to check the settings for your system.

Changing the default SSH port on a VPS

Changing the default SSH port on VPs is a best practice for Linux server administrators and a security precaution. This setting is used to access a server remotely and securely over an unsecured network. Hackers typically look for open ports to intercept sensitive data. By amending this setting, you will be giving yourself extra protection against such a threat. To make the change, run sudo vim /etc/ssh/sshd_config. In the SSH configuration file, find the line “#Port”. Now type the new port number into the box provided. Do not log out of the previous root session until you’re sure that you can connect to the new port.

SSH change port connections to a VPS use the default port of 22. If you have a default SSH port, you can change this to a higher number, such as 2522. Most SSH connections don’t provide the port information, but you can change it by editing the /etc/ssh/sshd_config file. Make sure the firewall doesn’t block the new port, and restart the ssh daemon.

Advanced settings allow configuring multiple ports

Unlike the basic SSH configuration, the advanced settings let you set a different port for each connection. You can also obfuscate the protocol, which makes it more difficult to crack, or restrict outbound connections to a certain port. If you’re concerned about drive-by attempts to guess your password, you may want to disable password authentication. To disable password authentication, you’ll need to edit the configuration file and test it.

To configure multiple ports for SSH, open up the /etc/ssh/sshd_config configuration file. Restart the sshd service to make the changes take effect. Note that some operating systems, including SELinux, don’t allow non-standard ports. You can’t configure ssh to run on non-standard ports, so make sure to use a SELinux-compatible firewall if you’re using SELinux.
