Failed to start DBG session using ssh tunnel and openvpn |

sounds like you have to re-check if SSH tunneling in PhpED is configured in your project.
Run project settings wizard. On the page where it asks about connectivity, make sure that your SSH Tunnel account is selected. Also when you run debugger, check View->Tab->Tunnels to make sure that the tunnel is active. NOTE that when you run your VPN it most definitely breaks all connections, including the tunnel one. |

Hello Dmitri, I confirm that the ssh tunnel is checked and when the project is started in the log I see that the debug session has correctly established. Moreover on the server I see the tunnel active when it starts. Moreover when a profiling session is started I see the new connection on the server, but it seems that the reply doesn't arrive to the client.
I've started the OpenVPN connection before starting the debug connection and before phped starts the debug tunnel. Very weird. The same problem is happening on two different pc/clients. Any idea? |

Hello,
here the new tests done this morning - step by step steps 1) PHPED closed 2) login on the remote server to debug: # netstat -nap|grep 7869 # No output 3) on local pc C:\Users\pc\Desktop>netstat -an|grep 7869 C:\Users\pc\Desktop>telnet localhost 7869 Connessione a localhost...Impossibile aprire una connessione con l'host. sulla porta 7869: Connessione non riuscita [unable to open a connection] 4) Started OpenVPN connection (configured in order that all the traffic goes through the VPN). 5) Opened PHPED (not on the project to debug remotely). Nothing appears on the client and on the server 6) I active the project to debug remotely in PHPED. in phped log tab I see: Tunnel [tunn_name] remote tunnel successfully established on localhost:7869 12:02:52 7) on the remote server I see: [root@ip-172-31-43-236 centos]# netstat -nap|grep 7869 [root@ip-172-31-43-236 centos]# netstat -nap|grep 7869 tcp 0 0 127.0.0.1:7869 0.0.0.0:* LISTEN 1193/sshd: www53797 tcp6 0 0 ::1:7869 :::* LISTEN 1193/sshd: www53797 on the local pc I see: C:\Users\pc\Desktop>netstat -an|grep 7869 TCP 0.0.0.0:7869 0.0.0.0:0 LISTENING TCP [::]:7869 [::]:0 LISTENING 9) the "telnet localhost 7869" on the local pc opens a communication and after some carriage returns it exits 10) after step 9 in PHPED debug log tab I see (due to the telnet): Debugger data fetch timeout, disconnecting 12:04:21 11) I start a profiling session on the remote server. 12) on the server I immediately see: [root@ip-172-31-43-236 centos]# netstat -nap|grep 7869 tcp 0 0 127.0.0.1:7869 0.0.0.0:* LISTEN 1193/sshd: www53797 tcp 0 1 172.31.43.236:53864 79.11.247.189:7869 SYN_SENT 8779/php-fpm: pool <===== tcp6 0 0 ::1:7869 :::* LISTEN 1193/sshd: www53797 13) on the client browser I see: DBG 9.1.10 Failed to start DBG session Reason: failed to connect to the client at <my vpn ip>:7869, please make sure that IDE is running 14) in phped there is no line in the log 15) locally if I do a new "telnet localhost 7869" I see the communication starting and in the phped log "Debugger data fetch timeout, disconnecting 12:09:30" 16) during the local telnet I see locally: C:\Users\pc\Desktop>netstat -an|grep 7869 TCP 0.0.0.0:7869 0.0.0.0:0 LISTENING TCP 127.0.0.1:7869 127.0.0.1:50977 TIME_WAIT <====== TCP [::]:7869 [::]:0 LISTENING But I don't see the second line during the profiling session. 17) It seems that the debugger is unable to talk over an openvpn connection; here my .ovpn file: remote <vpn remote ip> 1194 float nobind proto udp dev tun sndbuf 0 rcvbuf 0 keepalive 15 60 comp-lzo adaptive auth-user-pass client auth MD5 remote-cert-tls server <ca> -----BEGIN CERTIFICATE----- [...CUT...] -----END CERTIFICATE----- </ca> <cert> -----BEGIN CERTIFICATE----- [...CUT...] -----END CERTIFICATE----- </cert> <key> -----BEGIN PRIVATE KEY----- [...CUT...] -----END PRIVATE KEY----- </key> Any idea? could you please test on your end too using an OpenVPN connection?

Perhaps, there is nothing for me to test, at least I don't see anything.
What you need is run project settings wizard and update connectivity -- you have to check tunnel option if you want to use ssh tunnels. Regarding your tests 9) should be performed on the server, not on the client 13) is expected to show localhost in case if tunnel is to be used. But neither is as important as project settings wizard. |

Wizard succeeds with no error, but profiling fails.
Could you please try running a remote profiling with ssh tunnel and OpenVPN? The OpenVPN connection is working fine for the other operations, I've shown my config file. I don't know where to look further. Tnx |

tests done.
connected with ssn tunnel without vpn step 9 on the client and on the server both have the same result. They are able to open a telnet session with localhost on port 7869 and after the telnet session ends in the PHPED log I see: "telnet localhost 7869" run locally: Debugger data fetch timeout, disconnecting 08:38:52 "telnet localhost 7869" run remotely: Debugger data fetch timeout, disconnecting 08:39:32 Now I've switched to another phped project, the tunnel was closed properly (Tunnel [<tunnel name>] remote tunnel on localhost:7869 is closed 08:39:48 ) Now I've started the openvpn connection and switched to the phped project with this problem; in the log tab I see: Tunnel [<tunnel name>] remote tunnel successfully established on localhost:7869 08:41:24 local telnet is fine: "telnet localhost 7869" run locally: Debugger data fetch timeout, disconnecting 08:38:52 remote telnet is fine too: "telnet localhost 7869" run remotely: Debugger data fetch timeout, disconnecting 08:45:43 I try to start profiling on my remote project: https://<website>/dbg-sample.php Nothing in the PHPED log and in the browser I see: DBG 9.1.10 Failed to start DBG session Reason: failed to connect to the client at <vpn ip>:7869, please make sure that IDE is running Not sure what it means?
