The user can specify a timeout in seconds. This 6*4882a593Smuzhiyun is useful in shell scripts running in firewalled 7*4882a593Smuzhiyun environments. Often SYNs are just being dropped by 8*4882a593Smuzhiyun firewalls, thus connection establishment will be retried 9*4882a593Smuzhiyun several times (for minutes) until a TCP timeout is 10*4882a593Smuzhiyun reached. With tcping it is possible to check first if the 11*4882a593Smuzhiyun desired port is reachable and then start connection 12*4882a593Smuzhiyun establishment. 13*4882a593Smuzhiyun 14*4882a593Smuzhiyun https://github.com/mkirchner/tcping 15
