Hi, I'm new to trying KGDB/KDB. My test machine doesn't have serial port. I've been trying to run it over internet. I get following dmesg log: KGDB: Registered I/O driver kgdboc On test machine command line: kgdboc=kbd sudo sh -c "echo g > /proc/sysrq-trigger" # Launch KGDB System freezes at this point meaning the debugger got activated correctly. But I'm unable to connect from host side: gdb vmlinux set debug remote 1 target remote <test_machine_ip>:2012 I may be missing something trivial. Please can someone point/correct me how to connect correctly? PS: kgdboe [2] seems like a out of tree module for help. But it doesn't seem to be supported anymore. Is it possible to connect from another machine over internet and debug the target? [1] https://docs.kernel.org/dev-tools/kgdb.html [2] https://github.com/sysprogs/kgdboe -- BR, Muhammad Usama Anjum
