Hi,

I'm copying the message below as written from an IRC guy mx8manger,
who contacted #nmap yesterday.
(CUT)

Since his message is a bit cryptic, I'll explain it here below.
Basically, what he tried was to nmap -sT scanme.nmap.org behind his
proxychains.  The error message, not included in his original e-mail,
but posted on the IRC, is following:

root () linux-pc:~# proxychains nmap -sV scame.nmap.org
ProxyChains-3.1 (http://proxychains.sf.net)

Starting Nmap 6.41SVN ( http://nmap.org ) at 2013-09-22 00:31 AST

|DNS-request| scame.nmap.org
|S-chain|-<>-127.0.0.1:9050-<><>-4.2.2.2:53-<><>-OK
|DNS-response| scame.nmap.org is 173.255.243.189

173.255.243.189/0 looks like an IPv6 target specification -- you have
to use the -6 option.
WARNING: No targets were specified, so 0 hosts scanned.
Nmap done: 0 IP addresses (0 hosts up) scanned in 1.56 seconds

(original source: http://paste.ubuntu.com/6138529/)

(he said that -sT reacts the same way). I marked it as a "possible
regression" because the guy said that this setup used to work with one
of the older versions of Nmap.

We probably don't have the e-mail address for the fellow. I attach the IRC
log.

Yours,
Jacek Wielemborek

Just wanted to let you know that this bug still affects current SVN.
