So why are 2 lines missing when I change the blocking factor from 256 to 512? Even cat reads in 16k blocks... Also:
% dd if=/proc/net/ip_conntrack bs=512 | perl -ne 'print length()."\n"' 0+2 records in 0+2 records out 153 138 169 151 167 139
No line is longer than 256 chars, so why are 2 lines missing when I read in 256 byte blocks?
