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. Learn more Unix Domain Socket: Using datagram Unlike stream sockets (tcp or unix domain socket), datagram sockets need endpoints defined for both the server AND the client. 2011-04-10 STREAMS is a general, flexible programming model for UNIX system communication services. STREAMSdefines standard interfaces for character input/output (I/O) within the kernel, and between thekernel and the rest of the UNIX system. The mechanism consists of aset of system calls, kernel resources, and kernel routines.

To be more precise, it's a way to talk to other computers using s The ssh client then tries to connect to /tmp/.X11-unix/X0 (on the local end, not the remote) to contact your X server. Now, maybe you don't have a X server running (are you on Mac?) or maybe the unix domain socket is not to be found in /tmp/.X11-unix which would mean ssh hasn't been configured properly at compile time. 3.
