"Timeout while reading response from Server"

UweT
Hi there,

Astaro's web filter is getting a pain in the neck. It causes more and more frustration.

Right now we have a class of students in a room who have to do an exam/a test online using www.coa2.co.uk (Java based).

Some students want to finish the test, some others want to access the website and the Astaro comes up with a client error window in the browser: "Timeout while reading response from Server".

Reviewing the web filter log I even see different URLs having that problem: 


2012:02:03-11:23:18 disgwac httpproxy[6111]: id="0002" severity="info" sys="SecureWeb" sub="http" name="web request blocked" action="block" method="POST" srcip="172.16.2.42" dstip="194.168.43.38" user="" statuscode="502" cached="0" profile="REF_KbKfywLeRp (School)" filteraction="REF_DefaultHTTPCFFAction (Default content filter action)" size="0" request="0xa3a1330" url="www.coa2.co.uk/.../" exceptions="av,auth,content,url,ssl,certcheck,certdate,mime,cache,fileextension" error="Timeout while reading response from Server"

2012:02:03-11:23:18 disgwac httpproxy[6111]: id="0002" severity="info" sys="SecureWeb" sub="http" name="web request blocked" action="block" method="GET" srcip="172.17.9.11" dstip="67.195.187.57" user="" statuscode="502" cached="0" profile="REF_mLsJvVcVuk (WLAN-CommunityRoom)" filteraction="REF_iKcUWRpPYS (CommunityRoom_Action)" size="5293" request="0x6d301a30" url="prod1.rest-notify.msg.yahoo.com/.../uta_siebert

2012:02:03-11:24:51 disgwac httpproxy[6111]: id="0002" severity="info" sys="SecureWeb" sub="http" name="web request blocked" action="block" method="GET" srcip="172.16.2.129" dstip="94.100.179.72" user="asachechelashvili" statuscode="502" cached="0" profile="REF_KbKfywLeRp (School)" filteraction="REF_jufcKIaXDn (Students_Action)" size="4835" request="0x8432d1a8" url="jim12.mail.ru/connect


These are just 3 examples of many lines repeating in similar form.

The website above I had/have already excluded from everything: AV Scanning, URL ContentFiltering... but it doesn't help.

Do you have any suggestions?

Sincerely,
Uwe

    I made the changes and I thought we (by "we" I mean "you") had it there.

    Looked good for about a minute...

    Why am I even seeing this in the logs if it's in the transparent skip list?

    source 172.20.1.200 what ip is that?

    (ADSSO)
    are you using http proxy in standard mode with authentication?

    Transparent mode authentication is set to "none"

    hrmm my post got lost..[:)]  try disabling the proxy and setup a firewlla rule that lalows http traffic.  Does everything work then?

    Strangely, no.  It does the same thing:  I am able to connect for a minute or so then I'm disconnected.

    ok have you setup shell access yet?  if so login as root and do an ifconfig eth(whatever number your wan interface is) and see if there are any errors noted

    it also appears you have support..have you activated them yet?

    Here's the ifconfig

    I contacted support about a week ago.  Worked with them for about an hour then he was going to check with a senior tech and get back with me.  I've not heard from him even after pinging for a follow up a couple of times.  That's why I thought I would bring my issue here thinking that surely someone else had run into this problem.
