1 config BR2_PACKAGE_TCPING
4 tcping does a TCP connect to the given ip/port
5 combination. The user can specify a timeout in seconds. This
6 is useful in shell scripts running in firewalled
7 environments. Often SYNs are just being dropped by
8 firewalls, thus connection establishment will be retried
9 several times (for minutes) until a TCP timeout is
10 reached. With tcping it is possible to check first if the
11 desired port is reachable and then start connection
