cannot access gmail when bypassing proxy server (sometimes not always !!!!????)
-
and this what lower my self confidence sometimes when i cannot find a cause for an IT problem, or a solution for it, since i don't have strong IT experience this take it toll on me
-
Using Squid proxy is definitely a more advanced UNIX task.
For your light need, have you considered something more simple like using hosts files? Really simple to maintain.
-
but if use only host file, sure there will be some users who will manage to access those blocked website, i think it is not a reliable solution, isn't it???

Can't the work around by using HTTPS now?
-
It's easier to work around all this than it is to not because you can make an external hairpin to bypass pretty much any proxy. Even billion dollar international firms can't really get around that easily.

I used to use Squid, but now use Trend Micro Worry-Free Business Security installed on all my clients. This handles antivirus and web protection, and the GUI makes it very easy to block specific websites or categories of websites. I haven't implemented any Active Directory integration, which is limiting, but I'm not sure how easy that is with Squid either?
I'm also trialling GFI Webmonitor, which offers a similar service but is cloud based, and therefore easier to manage our home workers.
But I used to like the Squid logs for investigating what users were up to at any given point in time. Neither Trend or GFI provides that functionality. So I may go back to Squid.

what about this temporarily nature of this problem, anyone can guess with me how this occur only sometimes ????!!!!!
-
can this have any explanation ?????
-
I think we need a network map to understand exactly how things are flowing through the existing proxy.
-
ok, i will make a simple network map to make thing more clear
thank you very much
-
Thanks.
-
ok, my network map is the following, if someone can guess with me why this problem happen only sometimes,
thank you so much fir any clarification ...
-
Thanks, that helps a lot.
-
hopefully someone give me an explanation why this problem occur
-
We're wracking our brains on this but it is very odd, which, of course, is why you are having the issue
My only guess is that it has to do with the transparent proxy situation. The proxy is in line for all traffic, so it might be somehow interfering in an unpredictable way, but I cannot determine how.

hhhh
tell my Mr Scott, did you ever face such situation when you find yourself unable to explain the cause of a problem, you can imagine how it is embarrassing, especially in the business environment, when your manager tell you : why you didn't find a solution for this problem, lol -
but i think only people like me who lack strong experience who face this problem

Everyone does. The real difference with experience, I think, is recognizing when troubleshooting something complex is not a good use of time and working around it or approaching it differently helps. Of course, with experience, your troubleshooting will improve so you solve a higher percentage of challenges, but the challenges tend to get harder too.
In your case, I recommend working around, at least temporarily so that you can make the business happy and deal with finding an "ideal" solution when time allows.

It's the nature of such a complex business. IT systems have so many moving parts and so many of them (millions, literally) over which we have no direct control. There is no way for the IT department to have total control, it's just not possible. Sometimes things cannot be solved in any reasonable way.

thank you very much for you consolidation
