systemtap and other low level kernel tracing/debugging systems as already mentioned; insert a man in the middle. For the MITM, you could for instance use socat. Here for a connection oriented Unix domain socket like for X11: socat -x unix-listen:/tmp/.X11-unix/X42,fork unix:/tmp/.X11-unix/X0 DISPLAY=:42 xlogo

udtrace - Unix Domain socket tracing This is a LD_PRELOAD wrapper library which can be used to trace the data sent and/or received via unix domain sockets. Unlike IP based communication that can be captured/traced with pcap programs like tcpdump or wireshark, there is no similar mechanism available for unix domain sockets.

You can use the socketpair function to create a pair of connected UNIX domain sockets. The pair of sockets is unnamed; that is, they are not bound to a file path. Display UNIX domain sockets To display the active UNIX domain sockets that are on your system, use the ZDTCP command with the NETSTAT parameter specified.

Unfortunately there are no perfect tracers at the moment for Unix domain sockets that produce pcaps (to my best knowledge). Ideally there would be a libpcap format that has a header containing the source/dest PID (when available) followed by optional additional data (credentials, file descriptors) and finally the data.

The first, unix_server_socket.c, creates a passive socket and accepts connections. For each connection, it will read from the socket and echo the results into STDOUT. The second,...

Reading a Unix Domain Socket file using Python is similar to an ordinary TCP socket: >>> import socket >>> import sys >>> >>> server_address = '/tmp/tbsocket1' # Analogous to TCP (address, port) pair >>> sock = socket.socket (socket.AF_UNIX, socket.SOCK_STREAM) >>> sock.connect (server_address) >>> sock.recv (512) '*** uWSGI Python tracebacker output …

On Resol’s side, the procedure goes as follows: Resol creates a socket by calling socket () . int listen_sock = socket(AF_UNIX, SOCK_STREAM, 0); Resol assigns the socket a name. In case of UNIX socket, the name is exactly a filename. Resol bind () the socket with a filename. // We need extra steps to create the _addr_ variable.

UNIX and. Linux. systems. Use the strmqtrc and endmqtrc commands to start and end tracing, and dspmqtrc to display a trace file. The trace facility uses a number of files, which are: One file for each entity being traced, in which trace information is recorded. One additional file on each machine, to provide a reference for the shared memory ...

This answer is for Linux only. Update for Linux 3.3: As Zulakis wrote in a separate answer (+1 that), you can use ss from iproute2 to get a pair of inode numbers for each socket connection identifying local end and peer. This appears to be based on the same machinery as sock_diag(7) with the UNIX_DIAG_PEER attribute identifying the peer. An answer by Totor over at Unix & …
