I'm using ubuntu(linux) and changing FORTE to send Ethernet packet.

What I have done until now.

1 Enable your user to run gdb as root without being asked for any password:
sudo visudo
Add the following line after all other rules:
myusername ALL = (ALL) ALL
myusername ALL=(root) NOPASSWD:/usr/bin/gdb

2 Create or modify a debug configuration in eclipse to run gdb as root
e.g. in Run > Debug Configurations > C/C++ Application > YourProject Debug:
change Debugger > Main > GDB debugger from gdb to sudo -u myusername gdb

but this solution doesn't work, I get "socket: Operation not permitted".

Could you give me some insights into it?

Thank you.

Hi,

so you changed FORTE to send some other kind of Ethernet messages? Perhaps you have just introduced a bug?

Your approach to starting gdb as a privileged process seems right, but it would be better just to grant gdb the needed capabilites. Then you would also not need to run gdb with sudo.

Best regards,
Martin
