bool "tcping"
help
tcping does a TCP connect to the given ip/port
combination. The user can specify a timeout in seconds. This
is useful in shell scripts running in firewalled
environments. Often SYNs are just being dropped by
firewalls, thus connection establishment will be retried
several times (for minutes) until a TCP timeout is
reached. With tcping it is possible to check first if the
desired port is reachable and then start connection
establishment.
