Create a ControlPath socket with something like "-o ControlPath=/tmp/sshcontrol-%C" during an SSH connection. 2. Check with ls the socket is there. I am getting srw------- 1 enzo enzo 0 2016-06-17 10:17:21 sshcontrol- 369d1187d3900c559f063f947218528001d0e705 3. Ask lsof who's that socket belonging to: lsof /tmp/sshcontrol-369d1187d3900c559f063f947218528001d0e705 4. Ask lsof the same but with grep lsof | grep /tmp/sshcontrol-369d1187d3900c559f063f947218528001d0e705 ACTUAL RESULTS. For step no. 3 I am getting nothing (but the WARNING about /sys/kernel/debug/tracing) For step no. 4 I am getting: [enzo@Feynman ~] lsof | grep /tmp/sshcontrol-369d1187d3900c559f063f947218528001d0e705 lsof: WARNING: can't stat() tracefs file system /sys/kernel/debug/tracing Output information may be incomplete. ssh 10667 enzo 4u unix 0x0000000000000000 0t0 173813 /tmp/sshcontrol-369d1187d3900c559f063f947218528001d0e705.NDScoG3mgs0mWc4q type=STREAM Where you can see clearly that the socket name has a trailing part ".NDScoG3mgs0mWc4q".
