Proxy Issue - Curious

AlexR

I have 3 VPS with the same 20 private proxies on each for my test.

I have used the exact same:

URL: http://www.adobe.com/

String: id="shSignOutLink"

I have changed the order I do the proxy test on (i.e the order of the VPS's)

Here are my results:

1) VPS 1: 14/20 (i.e. 6 dead)

2) VPS 2: 20/20 (i.e. 0 dead)

3) VPS 3: 06/20 (i.e. 14 dead)

Scrapebox Test: 06/20 (i.e. 14 dead) (I did this after all the other tests)

How is this possible? No projects are running. Proxies are not used for anything else. I have restarted GSA a few times. I have changed the order I test the proxies on the VPS's. 

How can each VPS (with same provider and in EU), tell me that a different number of proxies are working???

So is it 

20 work?

14 work?

6 work?

Any ideas???

Just did another test. I changed the string as per https://forum.gsa-online.de/discussion/comment/10677#Comment_10677

URL I used: http://www.pr0.net/deny2/azenv.php

String: HTTP_CLIENT_IP

Results:

1) VPS 1: 06/20 (i.e. 13 dead)

2) VPS 2: 07/20 (i.e. 0 dead)

3) VPS 3: 02/20 (i.e. 14 dead)

Again, different results...

can be anything, your slow network, bad routing, slow proxies...

I've been using this one ( the one you recommended to Ozz):

URL I used: http://www.pr0.net/deny2/azenv.php

String: HTTP_CLIENT_IP

But it's kicking out brand new unused private proxies??? 

Whereas this one shows success on the same proxies:

I have used the exact same:

URL: http://www.adobe.com/

String: id="shSignOutLink"

Can you answer the following for me?

1) Which is a good string and URL to test private proxies on?

2) Would it be possible for you to add a feature where it has maybe 5 pre-approved test strings and URLs???

3) When GSA is running, how does it know if a proxy has gone dead?

I read a nice thread about this Proxy Judges at BHW

If you port scan for proxies. Do not use publicly listed proxy judges.
The owner of judge does not get your proxy port but they will get the
proxy IP; of course they will attempt to scan in first place against the
common ports to steal your proxies.



You're better off by setting up your own private judge on your server. Here is source code for the famous and old ProxyJudge http://myproxylists.com/prx.txt



For Linux: Just copy the text file to to your /cgi-bin/prx.cgi and do chmod +x prx.cgi

For Windows: Just copy the text file to your \cgi-bin\prx.cgi



Needless to say, private judge is a lot faster and more reliable as well
compared to public judges. This is very important thing to notice
unless you don't want crappy results.


if you still want to use public ones ... try :

Thats the exact reason why I didn't add such a proxy checking webpage as default url/string to test things with. Im very well aware that people proving these public check websites steal proxies.

So the easiest way to check if a proxy is alive or not is by using a common URL like www.bing.com and check it against a string that always appears there like microsoft.com. If the program can download it and finds this sting, it assumes it got a valid reply and not some error page or a proxy authorization page.

@sven

I wasn't referring to a proxy checking webpage. Good to know about them stealing proxies though!

I was referring to having a few common URL's and linked strings. 

It's just I am getting such diverse proxy results on various test strings and URL's.

(as you recommended to Ozz in a previous proxy post)

URL I used: http://www.pr0.net/deny2/azenv.php

String: HTTP_CLIENT_IP

But it's kicking out brand new unused private proxies??? 

Whereas this one shows success on the same proxies:

URL: http://www.adobe.com/

String: id="shSignOutLink"

Sorry there are 3 sites in it that can influence the result.

Your PC, the proxy and the website going through the proxy. I wouldn't rely on that www.pr0.net too much.
