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. This LD_PRELOAD library intercepts the C library function calls of dynamically linked programs. It will detect all file descriptors representing unix domain sockets and will then print traces of all data sent/received via the socket.
