Hi, I've commited to CVS latest changes with following major update: - ipv6calc is now able to read input from stdin (got feature request) Example: $ cat /proc/net/if_inet6 | awk '{ print $1 " " $3 }' | ./ipv6calc --ifinet6_to_compressed fe80::38cd:70ff:fe**:****/64 ::1/128 - ipv6loganon is fixed to support pipe also proper, so for on-the-fly anonymization in Apache following can be used: CustomLog "|/usr/local/bin/ipv6loganon -a -f /var/log/httpd/access_log" combined or in conjunction with cronolog: CustomLog "|/usr/bin/ipv6loganon -f |/usr/sbin/cronolog /var/log/httpd/access.log-%Y%m%d" combined Some other features are added like GeoIP IPv6 support and default location for IP2Location database files. Please test current CVS version and report problems, if any. I would probably release final version in a week or so. Regards, Peter
