Hi All,
I've compiled Linux kernel 2.6.16 with kgdb on Linux. And after that, I've tried to debug this kernel with Qemu 0.8.1 on Msys to simulate ARM Processor. In fact, I've run the command below:
qemu-system-arm -kernel myKernel -initrd arm_root.img -s
But I can't make the connection from arm-toolchain-gdb to the port 1234 (by default, this port must be openned by Qemu when using the option -s for debugging)
Furthermore, I've confirmed if the port 1234 is openned or not with the command: netstat -ao and there is not port 1234 openned. I've also try the option -p 123456 to change the default port for debugging of Qemu but I've got the same result.
Do you know where the problem arrive?
Thank you so much for your support.
Best regards.
Thanh

Port 1234 is the port on the virtual machine's IP address, not the port
on the real machine's IP address. So you need to be able to access the
virtual machine's IP address from the real machine. For this you can use
tun/tap networking - see the docs. It is not possible to do this with
user-mode networking.

In fact, I can connect by using the port 1234 on Linux with the command: (I use arm-toolchain and run the command: arm-linux-gdb vmlinux)
(gdb) target remote localhost:1234
And the debugging mode run well (normally) but the problem arrives when running on Windows with Msys/MinGW
Furthermore, I had tried make the connection for debugging (target remote qemu-machine:1234) between localhost and Qemu as 2 computers on a LAN but it is not possible; although I can make ping between these 2 computers
Do you have any suggestions for this problem?

Acutally you don't need networking in the guest. QEMU listens on the
host's port 1234 (and I think it listens on all interfaces, not only
localhost, but I'm not sure of this one -- if this is not the case,
make a ssh tunnel to debug remotely).

Hi,
Have you already read my previous reply? I wrote that:
[quote]
In fact, I can connect by using the port 1234 on Linux with the command: (I use arm-toolchain and run the command: arm-linux-gdb vmlinux)
(gdb) target remote localhost:1234
And the debugging mode run well (normally) but the problem arrives when running on Windows with Msys/MinGW
Furthermore, I had tried make the connection for debugging (target remote qemu-machine:1234) between localhost and Qemu as 2 computers on a LAN but it is not possible; although I can make ping between these 2 computers
[/quote]
So as you wrote, it must make the UDP connection between localhost and qemu? Because I don't understand exactly what you want to say in term of "ssh tunnel to debug remotely".

Yes, you're right. Sorry - I had misread the email and assumed the
original poster was trying to connect to a debugger running on the
guest.

I recently try the patch you recommend but I got the same result. In fact, after make this patch into Qemu source code 0.8.1, I compiled it with these commands:
./configure --prefix=/travail/install/qemu-8.1
make install
And I run Qemu to simulate ARM on debugging mode:
./qemu-system-arm -kernel myKernel-with-kgdb -initrd arm_root.img -s
And I tried to connect to Qemu by default port 1234: (gdb) target remote localhost:1234
But I got the error: connection refused
So I test the current openned port in localhost by the command: netstat -ao
And the result I got is below:

MinGW's gdb doesn't support network debugging. You need to use Cygwin's gdb
for remote debugging with network.

Port 1234 doesn't open. The program doesn't work well. If you use the patch
, TCP 1234 port will be used. Did you see this message?

I installed gcc-4.0 toolchain (so it also include gdb) from http://www.gnuarm.com/ to debug the code generated for ARM Linux.
And I did not install Cygwin because when I had installed this gcc-4.0 toolchain, the installer had asked me if I want to install the files .dll used by Cygwin in case of I had not installed Cygwin as well. Finally, it means I did not installed Cygwin but installed gcc-4.0 toolchain and I can run well the command (used for debug ARM Linux code): arm-elf-gdb

I said that I've applied this patch to source code and recompiled this source code but I got the same problem.
For the msg: "Waiting gdb connection on port 1234", I did not see this message in the screen of Msys (because I think that Qemu must use stdio to print the message on the console of Msys but there is not stdio in Msys/Windows) but I don't know if it can be printed on the screen (the new window for Qemu when running Qemu from Msys) of Qemu or not; because this screen scroll very fast and I could not see all the messages on the screen.
So do you have any suggestions to see all of which printed on the screen of Qemu? And any solutions to test if the port 1234 is already openned or not? Or any another patches?
Thanks so much and best regards.

MinGW's gdb doesn't support network debugging. You need to use Cygwin's gdb
for remote debugging with network.

Port 1234 doesn't open. The program doesn't work well. If you use the patch
, TCP 1234 port will be used. Did you see this message?
Waiting gdb connection on port 1234
