By default, webalizer truncates the useragent field to 64 characters, which tends to cut off bits useful for useragent grouping. The following line added to the end of src_unpack() should double the current size of the buffer. sed -i -e 's:^#define MAXAGENT 64:#define MAXAGENT 128:' webalizer.h If you add it, I'll be your best friend ;)
