[Help] Setting Proxy Problems

English Network/Internet
#1

Firstly, I want to state that I’m really new in Linux and also I’m not really good in networking stuff.

I use Wi-Fi (WPA) connection in my school. I followed the guide on how to setting the proxy for Konqueror and Firefox. They work perfectly fine.

I tried to set proxy for Google Chrome, I did realize Google Chrome use the same setting as Konqueror. I thought it might be working. But, when I tried to surf using Google Chrome, it’s not working. The request always times out.

What should I do to fix it up? I do really need Google Chrome, because it does help me with the zoom ability. The zoom ability is good enough but not as good as IE8.

Another question, when I tried to use Software Management and refresh some repos, the Error box(es) always pop-up saying that:


Error

Download Failed:
Failed to download /content from http://download.opensuse.org/....
History:
-[AbstractCommand.cc:195] URL=http://download.opensuse.org/....

I thought it might be concerning about proxy. As I tried it at home, the Error box(es) never appeared. How to set the proxy for the Software Management?

The proxy for my school is:

http://wpad.r***.edu.**/wpad.dat

I do appreciate any kind of helps :).

That looks like an autoconfiguration URL - you might try just downloading
that file and see what’s in it.

Sorry, I replace my institution name into ***.

As I said before, I’m not really good on networking. I wonder how did you know that it was autoconfiguration URL. How to differ auto-config and manual-config? Sorry, if I’m asking stupid questions.

I bet Jim has seen more of these.

It was an educated guess - the target of the URL was a filename, so it
seemed to be a good guess.

So what I would probably do is configure the browser proxy settings to
point to proxy.r****.edu.** port 8080 - in theory, that should do the
trick. This autoconfig file seems to point to that - it tries to make a
determination based on several subnet address blocks, but it falls back
on the default proxy at the end of the file (after the “else”) which
should do the trick for you, I’m guessing.

No such thing as a stupid question when it’s something you don’t know the
answer to. :slight_smile:

Honestly, I’ve never seen one before - never actually used one. :slight_smile:

I have tried change the proxy to proxy.r*.edu.** port 8080**, but nothing changes at all using Google Chrome. When I tried using Konqueror, there was an Server Authentication - Konqueror box saying that:


The Server failed the authenticity check (its-wn-proxe.its.r***.edu.**).
The certificate is not signed by any trusted certificate authority

Here is the details:


Current connection is secured with SSL.

The IT Help Desk at my University didn’t know how to solve this problem :’(. I don’t know where to ask for help :’(.

This means you just need to set an exception for the proxy server’s
certificate. You should have an option presented that lets you use that.

For using the proxy in chrome, you probably have to set the Chrome proxy
settings (I don’t think it uses the system settings).
