Implement IPv6 support. Functional IPv6 support depends on an extended grammar, an extended parser, and also reading of "/proc/net/tcp6". . Using a union large enough to accommodate "struct in_addr" and "struct in6_addr" a unified evaluation of the two address family is possible. . The implementation of CIDR netmasks for IPv4 is conducted. . Finally, the manual pages are expanded.
Improve security in daemonised execution. Ignore signals irrelevant to a long living daemon which was crafted with orderly shutdown. . Replace standard file descriptors with a tie to "/dev/null". . Yield controlling terminal properly by seting session ID. ===================================================================
