- 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.
