       -H, --host
	      host name or numeric Internet address to scan

       -P, --port
	      port number to scan (single port scan only)

       -SP, --start-port
	      port number to begin the scan from

       -EP, --end-port
	      port number to end the scan at

       --last-host
	      uses the last scanned host as target

       --last-scan
	      performs again the last port scan

       -q, --quiet
	      disable console output and logs to file.

       -lf, --logfile <logfile>
	      log the results to a specified file.

       -nf, --no-fency
	      disable fency output

       -nc, --no-colors
	      disable colored output

       --configure
	      let the user configure knocker

       -h, --help
	      display this help and exit

       -v, --version
	      output version information and exit

EXAMPLES

       To run this program the standard way type:

       knocker --host 192.168.0.1

       If you want to specify a port range to scan:

       knocker --host thehost  --start-port 1 --end-port 2600

       or

       knocker -H thehost  -SP 1 -EP 2600

       To scan a single port:

       knocker -H thehost --port 21

       To run this program not using colors (if your terminal does not support colors):

       knocker --host 192.168.0.1 --no-colors

       To run this program run in background and have the results written in a log file:

Name
       socket_from_name - convert a name and port number to a socket address

Syntax
       #include <idl/c/socket.h>

       void socket_$from_name(family, name, nlength, port, sockaddr, slength,				status)
       unsigned long family;
       socket_$string_t name;
       unsigned long nlength;
       unsigned long port;
       socket_$addr_t *sockaddr;
       unsigned long *slength;
       status_$t *status;

Arguments
       family The  integer  representation  of	an  address  family.   Value  can be socket_$internet or socket_$unspec If the family parameter is
	      socket_$unspec, then the name parameter is scanned for a prefix of family: (for example, ip:).

       name   A string in the format family:host[port], where family:, host, and [port] are all optional.  The family is an address  family.   The
	      only  valid  family  is  ip.   If  you specify a family as part of the name parameter, you must specify socket_$unspec in the family
	      parameter.  The host is a host name.  A leading number sign (#) can be used to indicate that  the  host  name  is  in  the  standard
	      numeric  form (for example, #192.9.8.7).	If host is omitted, the local host name is used.  The port is a port number.  If you spec-
	      ify a port as part of the name parameter, the port parameter is ignored.

       nlength
	      The length, in bytes, of name.

       port   A port number.  If you specify a port number in the name parameter, this parameter is ignored.

       sockaddr
	      A socket address.

       slength
	      The length, in bytes, of sockaddr.

       status The completion status. If the completion status returned in is equal to status_$ok , then the routine that supplied it was  success-
	      ful.

Description
       The  routine converts a textual address family, host name, and port number to a socket address.	The address family and the port number can
       be either specified as separate parameters or included in the name parameter.
