Fallback to TCP when implicit Unix socket connection fails. Since kernel 3.3, it is possible using ss or lsof-4.89 or above — see Stéphane Chazelas's answer.. In older versions, according to the author of lsof, it was impossible to find this out: the Linux kernel does not expose this information.

Currently I create a pair of FIFOs for the read and write streams and connect to them using cat /tmp/dbg_write & cat > /tmp/dbg_read.This is workable and pretty straightforward, but if you don't exit everything just right you have to go back and kill the background cat command. Connect and share knowledge within a single location that is structured and easy to search.

Unix sockets allow inter-process communication (IPC) between processes on the same machine. Overview: Support for the unix socket has existed both in BSD and Linux for the longest time, History and implementations.

Binding Sample 3: No Linux Permissions, Windows Permissions. In this sample, a WSL Unix socket process connects to a Windows Unix socket path which it has access to from Windows, but not from WSL.
