Hello Laurent and Steve, Thanks for your comments. Sock is a program to test concepts in networks. It was developed by Richard Stevens, a great writer.
Sock has specific syntax and features as other programs. Then, my purpose is make available the program used in book "TCP/IP Illustrated - Vol I" [1] to students and readers. The students need the exact program to reproduce the examples. Besides, this package is more one option to users. Thanks a lot!
