![]() What we want to do is connect to the remote machine over SSH and set up port forwarding for port 9000 (for Xdebug 2), 9003 (for Xdebug 3), or 10137 (Zend Debugger). Set up an SSH tunnel to the remote machine Before launching the script, make sure that either a breakpoint is set or the Break at first line in PHP scripts option is enabled on the Debug page of the Settings dialog Ctrl+Alt+S. This will ensure IntelliJ IDEA reacts when a debugging session is started and opens the Debug tool window automatically. In IntelliJ IDEA, enable listening to incoming debug connections by either clicking on the toolbar/the status bar or selecting Run | Start Listening for PHP Debug Connections in the main menu. Listening for incoming debugger connections When using Xdebug, make sure at least the following settings are specified: In the CLI Interpreters dialog that opens, the Configuration file read-only field shows the path to the active php.ini file. On the PHP reference page that opens, click next to the CLI Interpreter field. In the Settings dialog ( Ctrl+Alt+S), click PHP under Languages & Frameworks. Open the active php.ini file in the editor: To avoid this problem, you need to update the corresponding sections in the php.ini file as described in Configure Xdebug and Configure Zend Debugger. These tools cannot be used simultaneously because they block each other. IntelliJ IDEA supports debugging with two most popular tools: Xdebug and Zend Debugger. Open the Marketplace tab, find the PHP plugin, and click Install (restart the IDE if prompted).īefore you start debugging, make sure that you have a debugging engine installed and configured properly. Press Ctrl+Alt+S to open the IDE settings and select Plugins. The PHP plugin is available only in IntelliJ IDEA Ultimate. This functionality relies on the PHP plugin, which you need to install and enable. This can be useful for debugging code on a remote machine when there are firewalls in between, or a NAT router prevents direct connection, or the ISP or network infrastructure does not allow incoming TCP connections to the developer machine. ![]() If you have any questions or ideas, please leave them in the comments section below.This tutorial describes how to use an SSH tunnel to setup a secure connection between the development machine and a remote server. 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.
