Connection to valgrind embedded gdb server is failing with an error "Connection reset by peer"

Question

I trying to follow the instruction on connecting to valgrind using gdb. Valgrind memcheck is starts properly and asks to connect using following gdb command:

target remote | vgdb --pid=53181

but when I run this command, I get an error

Remote communication error. Target disconnected.: Connection reset by peer

what is my mistake?

Answer 1

It appears that error

Remote communication error. Target disconnected.: Connection reset by peer.

is general and may indicate invalid command as well. If you run in gdb

target remote | something

it will give you the same error message.

It appeared for me, that extra space after | symbol was excess.

Correct command was actually

target remote |vgdb --pid=53181

My GDB version is GNU gdb (Ubuntu 10.2-0ubuntu1~18.04~2) 10.2
