Summary: Kopete doesn't use the KDE-configured Socks Proxy to
resolve DNS queries
Product: kopete
Version: 0.11.1
Platform: Compiled Sources
OS/Version: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: general
AssignedTo: kopete-devel kde org
ReportedBy: junkie go-a-way dyndns org
Version: 0.11.1 (using KDE Devel)
Installed from: Compiled sources
Compiler: GCC 4.0.2 (thread model: posix, host: i686-pc-linux-gnu)
OS: Linux
Hello,
I've chose Tor (http://tor.eff.org) as the gateway to some of my Internet uses
: Web-browsing & IM.
so I did install Dante (a Socks-client), Configured Dante, and then configured
KDE to use Dante as a Socks-client.
This Configuration works well (tested using Konqueror & Kopete).
Anyway, The issue was discovered when I wanted Tor to also resolve the DNS
queries on my behalf - for better privacy.
Tor, has a feature (and a matching config-setting) that logs whatever if It got
a target IP-address (bad for privacy) - or a Hostname (good for privacy), this
Tor config-setting is named "TestSocks".
After enabling this feature in Tor, I found that Kopete, in contrary to
Konqueror and Mozilla-Firefox, gives the Socks Proxy an IP-address (bad for
privacy) - instead of an Hostname (good for privacy).
I did my Kopete testing while connecting to the ICQ & MSN Networks.
When a program (like : Kopete-0.11.1) gives the Tor Socks-Proxy a an IP-address
instead of a Hostname, the log-message looks like this :
---
Mar 01 17:00:52.364 [warn] fetch_from_buf_socks(): Your application (using
socks5 on port 5190) is giving Tor only an IP address. Applications that do DNS
resolves themselves may leak information. Consider using Socks4A (e.g. via
privoxy or socat) instead. For more information, please see
http://wiki.noreply.org/noreply/TheOnionRouter/TorFAQ#SOCKSAndDNS";
---
and When a program (like : Konqueror-3.5.1 and Mozilla-Firefox-1.5) gives the
Tor Socks-Proxy a Hostname instead of an IP-address, the log-message looks like
this :
---
Mar 01 17:07:55.474 [notice] fetch_from_buf_socks(): Your application (using
socks4a on port 80) gave Tor a hostname, which means Tor will do the DNS
resolve for you. This is good.

This issue might put some of the ones who need protection from their "big
brother" (in non-democratic countries, in corrupted corporations & etc.), at
great danger.
If there's anything I can do to assist on solving this issue, Please do contact
me, and I'll do what I can.
Thankyou, for your greatly estimated work on Kopete :)
