Remote PHP Debugging

If you want to debug your scripts on a public server while sitting at home or in the office, or in other words your server is located in a different network than your development machine (so the server can not connect back to your machine), you have to perform additional steps in order to provide this connectivity. We recommend to run Project Settings Wizard first and check whether it shows same or different network in client outbound IP line in the results. In case of same, debugger module can work with IDE and only firewalls should be configured to permit communication on the debugger port. In case of different networks, you need either establish port forwarding on the NAT router or use SSH tunnel.

Setup remote debugging using SSH tunnels

SSH tunnel is a kind of data channel that opens in parallel with a regular ssh connection. It will transfer data between debugger module and IDE.

1. Make sure that SSH daemon (sshd) is running on your server. It is a common tool for all unix/linux based servers. If you're using Windows, you may want to try openssh service that comes with Cygwin and configured with ssh-host-config key which installs sshd as Windows Service
2. Start PhpED and open Tools->Settings->Run & Debug->Settings page. Check "Use SSH tunnel" checkbox and select <...Tunnels> in the dropdown. It will open tunnel settings. Enter hostname and correct port if necessary. Enter login name and authentication password. If your server requires public-key authentication, switch to Keys tab, right click on SSH settings and create new set of keys. Assign name as you wish in the list on the left panel. If you already have ssh2-compatible keys, enter their public counterparts to the "Public identity files" list. These files are expected to have .pub file extensions. All private keys are expected to be with the same file name in the same directory, but without any extensions. You can use openssh tools to generate key paris. PhpED supports rsa and dss keys.
Once new ssh tunnel account is created, select its name in SSH tunnel line in Debugger Settings and press [OK]
3. open php.ini on the server and make sure that debugger.hosts_allow contains localhost:

debugger.hosts_allow=localhost [::1]
debugger.ports=7869, 10000/16
You don't need any other addresses here because debugger module will connect to the tunnel's socket which is local to the server.
4. Open View->Tabs->Tunnels window and make sure that tunnel connection is established

Remote PHP Debugging with NAT forwarding

When web server and phped running on different networks, you can setup remote debugging via port forwarding feature of the NAT router. First of all, you have to locate the device through which your development machine is connected to the public network. Open cmd console and type ipconfig without parameters. It will show all network interfaces, their addresses and the addresses they are connected to -- Default Gateway. This gateway is address of the router you're connected to.

PHP Debugger Remote Port Forwarding
If it has an HTML interface, you can try to reach it in your browser by opening http://xx.xx.xx.xx/ where xx.xx.xx.xx is the address of Default Gateway. It will open configuration panel, and you'll be able to proceed with settings according to the device's manual. The feature you have to find is usually referred to as NAT port forwarding and lists 3 columns: inbound port number, target machine, and target port number. Sometimes it also allows you pick either udp or tcp protocol. Set both inbound port and target port to 7869 (or another port you've configured in the debugger settings), target host is the IP address of your development machine (shown in IP Address line above Default Gateway). If it allows to select protocol, please select TCP.

PHP Debugger Remote Automatic
If your router supports UPnP, PhpED can automatically setup NAT forwarding.
PHP Debugger Remote Check
When you select the option Router Supports UpNP port management, PhpED uses UpNP to open the communications with PHP Debugger and you don't need to setup Port Forwarding.

For UpNP to work:
  • Your router should support UPnP (almost all new routers do)
  • There are no additional requirements for Vista, Windows 7, or Win8 OS, but if you are running Windows XP, you have to install UPnP. Open Control Panel -> Add Remove Programs -> Add Remove Windows Components (button on the leftmost panel) -> Networking Services -> UPnP User Interface.
