I am having some problems with Privoxy that I cannot resolve.

Privoxy is slow. Very slow. On its own and with Tor, but the problem
is Privoxy.

Firstly, my config.txt file shows: listen-address 127.0.0.1:8118

My browser (Mozilla Firefox 1.0) uses this proxy for all connections.

I normally use ZoneAlarm but have tried turning it off when using
Privoxy, to no avail. IOW, it cannot be ZA blocking connections to the
localhost.

I constantly get the following error multiple times per website:

Jan 24 12:13:48 Privoxy(-2072989) Request:
www.google.co.uk/images/firefox/light.gif
Jan 24 12:13:53 Privoxy(-1979429) Error: Unable to get my own hostname:
WSANO_DATA - Valid name, no data record of requested type.

According to the Privoxy FAQ: "5.11. My logs show many "Unable to get my
own hostname" lines. Why?

Privoxy tries to get the hostname of the system its running on from the
IP address of the system interface it is bound to (from the config file
listen-address setting). If the system cannot supply this information,
Privoxy logs this condition.

Typically, this would be considered a system configuration error. It is
not a fatal error to Privoxy however, but may result in a much slower
response from Privoxy due to DNS timeouts."

Now, I have no idea why Privoxy does not understand what my hostname is
since the listen-address setting says it is 127.0.0.1

The problem manifests itself as follows: the computer receives
information from the Internet, then stops for a few seconds then starts
again. It is all the stopping that dramatically reduces the connection
speed. I am no expert, but this might well be one of the "DNS timeouts".

Incidentally, in Mozilla Firefox there is an option under General /
Connection Settings to choose "No Proxy For" a site or IP address. It
said "localhost" at one point, but whether that is there or not, makes
no difference to the slowness of Privoxy.

If it helps, I use a dial-up connection. I utilise ME.

Thanks for any advice offered. As stated, the slowness is down to
Privoxy rather than Tor. The latter is fine on its own.

Hint: that's an IP address, not a hostname. IP addresses are resolved by
DNS. You bound Privoxy (whatever that may be) to 127.0.0.1, the loopback
interface. Which, interestingly, does not appear in any DNS record (of
course).

Possible solutions:
        + Bind it to a real, resolvable interface (your external IP
works, but you should make sure that the proxy does not accept
connections from the internet or your ISP will kick you off after people
start complaining about abuse). This solution would make this post
vaguely appropriate for this group.
        + Make sure 127.0.0.1 is resolvable. Look for a hosts file
(c:\windows\hosts, /etc/hosts, or whatever it is on your system) and add
an entry for 127.0.0.1 (usually '127.0.0.1 localhost').

If this works, great. If it doesn't, please find a more appropriate
group to ask for help.

Yours,

                                Joachim
