NAME

6       bannergrab - a network service banner grabbing tool
7

SYNOPSIS

9       bannergrab [options] host port
10

DESCRIPTION

12       bannergrab  performs  connection, trigger and basic service information
13       collection. There are basic banner grabbing modes, the first mode  (the
14       default one) sends triggers to the services and performs basic informa‐
15       tion collection. The second mode (--no-triggers), only connects to  the
16       service and returns the connection banner.
17       By  default,  if  bannergrab  has a trigger for the port number that is
18       specified, the trigger for that port is used. If no trigger  is  listed
19       for  a  port,  the default one is used. No attempt is made to determine
20       the type of service operating on a port.
