You have a duplicate on lines 1386 & 1387 of your hosts file pulled down on 2009-Nov-19 21:49 UTC:
They are the same host. Host names are case insensitve
. I suggest just lower casing everything to prevent duplicates. Here is a list of all the hosts that have upper case characters:
ck47HFu.cn (just remove this one)
I suggest making them:
ck47hfu.cn (and keep this one)
Yeah, I know - NIT-PICKY! But it fouls up my automated script way of doing things and then I have to do most of it manually. I look at each and every host individually and manually, just like you do. Anything that speeds up what I do is a god-send. EMACS and other good editors (I use MicroEMACS on Linux & BSD) will just upper-case or lower-case everything with a tap of a few keys. I believe both NotePad++ and psPad (both free) will do it on Windows.
