Hello all,

I run CentOS on my Dell Precision system and i have already install a caching DNS server. Although the results wasn't what i was expecting, so i think that it is time to install a transparent proxy, using squid.

Is there any useful how to?? Has someone tested it?

Cheers,
Leo

I'm no expert myself..............

OK, can we take this piece by piece:

Which caching DNS server, in what way aren't the results not what you were expecting, and what testing have you done? (Like, did you use some specific DNS testing app, what did it show. What did you do about selecting upstreams, what do you actually see that is not what you want?)

Maybe, but what was your logic for deciding that transparent was the only way to go? Probably doesn't make much difference, but it would be nice to know.

Loads of stuff around. Almost any search on terms like "squid" and "tutorial", "how-to" or "configuration" will throw up some useful stuff. Probably with quite a bit of useless stuff, too.

Yes. There was a thread on this very site a few weeks ago comparing Squid against Polipo (squid lost in that informal test, btw). If I recall, the thread starter was TobiSGD. But apart from that, there are quite a few other sets of test results available. But beware, as with all benchmarking, the results that you get are very heavily dependant on exactly what you test.

Hello,

I install caching dns on my Centos and then I use the ip if the Centos server as a DNS in my windows system.
I done that in order to get faster response time when browsing the web.

Although as I already said above, I didn't saw a big difference, so I stop using it.

Today a friend told me that if I install a transparent proxy server ( he suggested squid) I will huge difference on my browsing speed.

So you suggest using polio?

So, thanks for not answering that question.

The simplest change I can make to that so that it makes sense is if -> of . That means that this system is using a windows PC as a client, and that does make a difference to how things work.

I don't suppose that you will see a huge difference in your browsing speed generally, but that does depend on some other details of your use case. In general, most people do not see much difference, although some scenarios are more favourable than others. The best that I would hope for is a modest improvement.

Had your objective been to reduce your data consumption, then it would probably have been easier to be positive about the prognosis. And, even if not that, there might have been some mileage from the increased flexibility, and, eg, the blocking options, but it seems that you don't want any of that.

Polio is really quite nasty, so I'll assume that was a typo, rather than an attempt to be funny about a tragic condition.

Polipo is simpler than squid (many fewer options and modes of operation) and probably has a higher chance of producing some speed-up than squid. I think that it has a better chance of ultimately being successful, but getting useful tutorials and optimisation suggestions is more difficult, as it is much less used. OTOH, being simpler, there is probably a much better chance that it "just works" without much optimisation.

Hello and thank you for your e-mail.
Sorry for the typo mistakes but i was replying from my iPhone.


I check out the website or polipo and i didn't understand many things! Do you have any easier how to guide?

I have never used CentOS but after a few mins of Googling I found a very basic snippet of setup instructions (it may or may not be of use and doesn't tell you how to make any custom configurations):

$ sudo yum install polipo"
REPORTS: polipo x86_64 1.0.4.1-2.el6 @epel
$ sudo service polipo start
REPORTS: /usr/bin/polipo -c /etc/polipo/config

Hello guys,

Has anyone configured Squid as a transparency proxy server?
Can someone please send the squid.conf file? ( configured! )


Thank you!
