| 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. | |
