client bug in 0.2.2.7-alpha and a new bad exit: exoassist

[Scott Bennett <bennett@xxxxxxxxxx>]

     There's another bad exit on the loose.  Its Nickname is "exoassist",
and its fingerprint is "39A6 74F8 2BFB 0195 860C 04DD E0F3 6B60 C09D C72A".
When trying to fetch a web page from www.fibrlink.net, I was surprised to
get an error page back from someplace in Australia, beginning with "The
requested URL could not be retrieved".  I took a quick look at the log,
made a guess at which exit it might be, and tried instead to fetch a web
page from www.fibrlink.net.exoassist.exit.  Once again, I got a web page
that says, between the dotted lines that I've added as delimiters,

     ...............................................................
The requested URL could not be retrieved
___________________________________________________________________
While trying to retrieve the URL: http://www.fibrlink.net.exoassist.exit/

The following error was encountered:

     Unable to determine IP address from host name for www.fibrlink.net.exoassist.exit

The dnsserver returned:

     Name Error: The domain name does not exist.

This means that:

 The cache was not able to resolve the hostname presented in the URL. 
 Check if the address is correct. 

Your cache administrator is webmaster.

     So it appears that a) there is a new tor client bug in 0.2.2.7-alpha that 
leaves the "exoassist.exit" in the name passed along from its SOCKS listener
to the destination port and b) "exoassist" is a bad exit that inserts a web
page into the stream returned to the client when a connection cannot be made.
     I'll add exoassist to my ExcludeExitNodes list, but it should also be
flagged ASAP by the authorities.
