The AS stands for American Standard and the Microsoft code pages are not US national standards. (Many national and international standards do have ASCII as a subset. The 8 bit one for the US is ISO 8859-1, which is closer to Microsoft 1252 (1252 replaces a secondary set of control characters by additional graphics. ISO 10646 (carefully numbered as ASCII is one of the variants of ISO 646), the code now most generally used, also has ASCII as a subset, and in its UTF-8 representation, ASCII produces the same machine representation (give or take byte order marks). The two common codes used in the Chinese language area, before ISO 10646 became common, also have ASCII as a subset, and represent ASCII text as single bytes. The ability of these codes to represent ASCII one to one is only there because ASCII is a seven bit code, ) ___ questions mailing list questions@lists.ntp.org http://lists.ntp.org/listinfo/questions

Oddly enough, if the character is has the high order bit turned on, it prints M- and then the character with the high order bit masked off. So, if the refid was 192.46.92.46 and it decided to run it through makeascii anyway, it would print as .M-F.\.. Now, while it looks like a valid IP address, it doesn't seem to be one of the servers that 204.109.63.243 is currently using (maybe previously?) nor does it explain why an IP address got printed as ASCII, but it does explain how we got 6 characters out of 4 bytes. However, it begs the question of why somebody thought that printing M- before characters with the high order bit turned on would be a good idea. -- blu Always code as if the guy who ends up maintaining your code will be a violent psychopath who knows where you live. - Martin Golding ---| Brian Utterback - Solaris RPE, Oracle Corporation.

Re: [ntp:questions] Strange refid
I think your data corruption idea is the most probable cause. If you look closely at the refid, it is 6 characters excluding the start and ending periods. I tried to create a refid of 6 chars, but it got truncated to 4.
