New weirdness in the system logs: dns queries for names that resolve to nearby IP addresses. At home, an xs4all IP:
Dec  7 08:51:34 gosper named[877]: denied query from [79.111.252.228].4233 for "luna.vulcan.nu" A/IN
Dec  7 08:51:34 gosper named[877]: denied query from [79.111.252.228].4235 for "zuul.xs4all.nl" A/IN
Dec  9 11:42:11 gosper named[877]: denied query from [212.46.197.83].54183 for "luna.vulcan.nu" A/IN
Dec  9 11:42:11 gosper named[877]: denied query from [212.46.197.83].54187 for "zuul.xs4all.nl" A/IN
Both names resolve to xs4all IPs in the same block as my home IP. On a resolver at work:
Dec 09 19:31:01.372 security: info: client 208.37.177.62#46262: query(cache) 'ns.uu.nl/IN' denied
Dec 09 19:45:57.494 security: info: client 204.11.51.61#43318: query(cache) 'ns.uu.nl/IN' denied
either coincidence or signs of some form of searching for security holes. In todays Internet I always assume the latter.
