name : undump_example.txt Demonstrations of undump.py, the Linux eBPF/bcc version. This example trace the kernel function performing receive AP_UNIX socket packet. Some example output: Terminal 1, UNIX Socket Server: ``` $ nc -lU /var/tmp/dsocket # receive from Client Hello, World abcdefg ``` Terminal 2, UNIX socket Client: ``` $ nc -U /var/tmp/dsocket # Input some lines Hello, World abcdefg ``` Terminal 3, receive tracing: ``` $ sudo python undump.py -p 49264 Tracing PID=49264 UNIX socket packets ... Hit Ctrl-C to end # Here print bytes of receive PID 49264 Recv 13 bytes 48 65 6c 6c 6f 2c 20 57 6f 72 6c 64 0a PID 49264 Recv 8 bytes 61 62 63 64 65 66 67 0a ``` This output shows two packet received by PID 49264(nc -lU /var/tmp/dsocket), `Hello, World` will be parsed as `48 65 6c 6c 6f 2c 20 57 6f 72 6c 64 0a`, the `0a` is `Enter`. `abcdefg` will be parsed as `61 62 63 64 65 66 67 0a`.
