объединение и перенаправление сокетов (Concatenate and redirect sockets)
ACCESS CONTROL OPTIONS
--allow host[,host,...] (Allow connections)
The list of hosts specified will be the only hosts allowed to
connect to the Ncat process. All other connection attempts
will be disconnected. In case of a conflict between --allow
and --deny, --allow takes precedence. Host specifications
follow the same syntax used by Nmap.
--allowfile file (Allow connections from file)
This has the same functionality as --allow, except that the
allowed hosts are provided in a new-line delimited allow
file, rather than directly on the command line.
--deny host[,host,...] (Deny connections)
Issue Ncat with a list of hosts that will not be allowed to
connect to the listening Ncat process. Specified hosts will
have their session silently terminated if they try to
connect. In case of a conflict between --allow and --deny,
--allow takes precedence. Host specifications follow the same
syntax used by Nmap.
--denyfile file (Deny connections from file)
This is the same functionality as --deny, except that
excluded hosts are provided in a new-line delimited deny
file, rather than directly on the command line.
