Hi, new version 0.94.1 was released today containing only bugfixes and code improvements. Because of some insecure and improper strncpy usage was replaced by snprintf update to 0.94.1 is very recommended. Credits to Peter Volkov who provides me information fixing the issue which was undetected on my Fedora / CentOS build systems. Package and signature files can be found here: ftp://ftp.bieringer.de/pub/linux/IPv6/ipv6calc/ ftp://ftp.deepspace6.net/pub/ds6/sources/ipv6calc/ Major extensions: none Hope this helps, Peter
