NAME

       unhide-tcp -- forensic tool to find hidden TCP/UDP ports


SYNOPSIS

       unhide-tcp [options]


DESCRIPTION

       unhide-tcp is a forensic tool that identifies TCP/UDP ports that are
       listening but are not listed by /sbin/ss (or alternatively by
       /bin/netstat) through brute forcing of all TCP/UDP ports available.
       Note : If iproute2 is not available on the system, option -n or -s
       SHOULD be given on the command line.


OPTIONS

       -h --help
              Display help

       --brief
              Don't display warning messages, that's the default behavior.

       -f --fuser
              Display fuser output (if available) for the hidden port

       -l --lsof
              Display lsof output (if available) for the hidden port

       -n --netstat
              Use /bin/netstat instead of /sbin/ss. On system with many opened
              ports, this can slow down the test dramatically.

       -s --server
              Use a very quick strategy of scanning. On system with a lot of
              opened ports, it is hundreds times faster than ss method and ten
              thousands times faster than netstat method.

       -o --log
              Write a log file (unhide-tcp-AAAA-MM-DD.log) in the current
              directory.

       -V --version
              Show version and exit

       -v --verbose
              Be verbose, display warning message (default : don't display).
              This option may be repeated more than once.

   Exit status:
       0      if no hidden port is found,

       4      if one or more hidden TCP port(s) is(are) found,

       8      if one or more hidden UDP port(s) is(are) found,

       12     if one or more hidden TCP and UDP ports are found.
