Can't connect to the gdbserver

[JulianH]

Hi,

i’m just porting a Visual Studio 2013 Windows Project to Linux in conjunction with VisualGDB. My building of the connections looks like:

Everything is compiling absolutly correct and the executable gets delivered correctly to 169.254.254.254, it starts even properly.

In htop on 169.254.254.254 i can see the running gdbserver with “gdbserver :2000 /tmp/VisualGDBTest” and /tmp/VisualGDBTest with “/tmp/VisualGDBTest” command line. But VisualGDB allways report if i try to debug a new instance (gdbserver and VisualGDBTest yet not run at this time) VisualGDB execute all my previosly enumerated steps then to say that gdbserver has report that the target process isn’t running. Here is the exactly appeared error message:

It allready worked but since i reinstalled VisualGDB and entered the licence key it does not.

With best regards

Julian Hindelang

Hi,

Please you enable GDB logging as described here and submit the detailed GDB log so that we could investigate it.

It’s maybe interesting:

This message appears immediately before the error-message posted in my first post appears:

Hi,

Can you ping your remote machine? If no, please check your IP address/subnet mask/gateway settings.

If yes, the firewall on the remote machine might be blocking the connections to the gdbserver. Please try disabling the firewall on the Linux side.

[JulianH]

I can connect to 169.254.254.254 to port 2000 i tested it with socat and with a gdb client by myself, both worked.

Just VisualGDB does not.

[JulianH]

My Firewall is completly turned off, Linux side i have no Firewall and no entries in the iptables.

If i try to connect to the gdbserver started by VisualGDB by command line, i get that:

Server side:

If i connect with VisualGDB, i only get the error as descripted above (without the recognizion from the gdbserver that someone tryed to connect).

I don’t know what i am doing wrong. It simply makes no sense to me.

The compiling linux server wasn’t in the same network like the linux execution server, i don’t understand why but putting them into the same network solved the problem.

This can be caused by lots of different causes ranging from ip/netmask settings to your gateway routing configuration. Putting both hosts in the same network is indeed the easiest solution.

So i say thank you.
