Ubuntu Security :: Cannot Access Forum After Installing Dansguardian
Nov 27, 2010
I have just installed webcontent control following these instructions - [URL] It has blocked the content that I wanted blocking but also when I try to access the ubuntuforum site, all I get it a white screen.what I need to adjust in the configuration so that I can access the forum with content control enabled.
I'm looking for the banana leaf desktop wallpaper which came with Jaunty Jackalope. Some kind person had all the archived wall-papers, but since I had to re-install I've lost it again.And by the way, how can I access my old postings to the web forum. Is this possible at all?
I am trying to add any web site into the exceptionsitelist for dansguardian, but I get cannot edit the exceptionsitelist file located at:/etc/dansguardian/listsSo, I tried to chmod 777 exceptionsitelist I was told that:chmod:ging permissions of 'exceptionsitelist': Operation not permittedAm I trying to add a site as a whitelisted site the correct way?If not, how do I do this?Please provide details on if this is done in a gui? ( I don't have a gui or know where it is located at least )What is the gui called?Where is it located ( under which mean like administration or preferences etc. )If there is no gui, am I looking in the correct folder for trying to add a web site for whitelist?Am I trying to whitelist correctly by adding a web site to the exceptionsitelist folder?I want to bypass everything dansguardian does. I read about greylist. I do not want to do that
I have installed squid and Dansguardian on Ubuntu Server 10.04. I have also installed webmin. I see that there is a Dansguardian module for Webmin, and I have downloaded it to the server, but I am not sure how to install it. The file was downloaded from [URL]I don't know what to do with the .wbm file.
Currently i am using the tutorial from Bodhi to setup Dansguardian to work togather with Privoxy and it worked fine.Then i installed Polipo to work with Privoxy which work as intented with additional forward the port to Privoxy.
Code:
Is it possible to run Polipo together with Privoxy? Yes. In order to get the privacy enhancements of Privoxy and much (but not all) of the performance of Polipo, you should put Polipo upstream of Privoxy.
In other words, you should:
point your web browser at Privoxy (localhost:8118); point Privoxy at Polipo (put forward / localhost:8123 in the Privoxy config file); use no parent proxy in Polipo.
Now i tried to use Dansguardian togather with Privoxy and Dansguardian with the same configuration but fail.
I've done some searching on googlubuntu for and answer to this but haven't found anything.
As a Linux newbie I was wondering if there are certain types of output from the terminal I should beware of posting for everyone to see? Also are there any codes; that, if I were to be asked to run and report the output on, should raise a red flag?
I am looking to redesign my network which I'll get into bellow but basically i am looking to setup an transparent/bridged firewall with squid and dansguardian. However, I want to require LDAP authentication to access internet. You'll understand why from diagram below.
My question is, since bridged firewalls operate at layer 2 and have no/require no IP address, can you access higher layered apps with them? Example would be to have the proxy authenticate to LDAP system to check for valid user and valid net permissions, server has to somehow send a reply back, so without an IP, this can't happen right.
Below are two designs I am looking into implementing. Everything Internally will be Authenticated against LDAP with a small possibility of some public servers using LDAP too, but in my way of thinking anything using LDAP would should be behind the router on private link. FYI, the PROXY and the Linux Router would be two physically separate systems. So I guess my second question would be, can systems outside private network access limited internal services securely and be restricted at the same time?
I have configured squid with AD. It is working fine. Now I want to use dansguardian with squid for web filtering on group bases, what should I do. What configuration i have to do in squid for dansguardian and all my users in AD also authenticate with dansguardian and also how I use dansguardian.
I just installed Ubuntu on a desktop. Can anyone give me some guidance on installing basic security software? In particular, I'm looking for a firewall, antivirus, and anti-spyware/malware utilities.
I'm concerned about security of having a LAMP server on my laptop as having any server makes the system less secure. However, if I were to create a new partition and install a lamp server on that and only use it when offline, would the security of my main partition be affected at all?
With an Ubuntu 10.10 upgraded from 10.04, under Software Sources, Updates, there is a radio button marked "Install security updates without confirmation." I have this radio button marked, but still get "Important security updates" almost daily in my update manager. I don't remember this feature actually ever working.

I'm the opensource nut at my company (which services MS networks) and I've been asked to set up an internal forum for our tech's to use to sever much like a knowledge base. I've never set up any forums before and was wondering what YOU guys recommend to use. I've briefly looked at Joomla and it seems nice and fairly easy to use.
linux i have configured squid with dansguardian but not able to block the sites and url.. i am accessing dansgaurdian through webmin.. please help me out in the above (with screen shots)
I'm trying to setup an SMF forum on a server running Ubuntu Hardy. The problem is that the website on the server was built using Django. So considering that Django uses Python and SMF uses PHP, would it be possible for both of these to coexist on the same server? If so, how? If this can't be done, I'm more than willing to rebuild the website in PHP. If I were to do this, then what do I need to do to reconfigure Apache? As of right now it's using mod_wsgi, but I'm assuming I would need mod_php. How would I set this up?
computer 8300 dell 82875 intel setup as follows:drive A master xp installeddev/sda master boot filesystem dev/sda1drive B slave ubuntudev/sdb (grub 2.863gb)grub.cfg set root=(hd1,1)until it gets to microsoft home edition, it changes to(hd0,1)drivemap (hd0)it automatically boots in XPi followed an example on windows xp in the forum for dual boot.
I've used the forums infrequently, being more of a mailing list kind of guy. But I'm currently tinkering with an old laptop I got as a "gift" which doesn't have an ethernet port, And if I wanted to use my cable modems usb connection to apt-get etc for the installed Ubuntu Lucid, I had to disconnect my router. This pc isn't yet configured with my mail client etc... So I thought I'd try the forum again...I noticed that using: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.2.3) Gecko/20100423 Ubuntu/10.04 (lucid) Firefox/3.6.3 Which has not been modified yet (except to add the scroogle search bar) I keep timing out.
IEI logged in to ubuntu forums, found an existing thread related to something I'd like to do with it.clicked on quote, and began composing a followup. When I was ready to preview the thread I got an error that said I wasn't logged in. and suggested I use some included form to try again. The form looked like it wanted my username and password but wouldn't let me enter the required info into the blank fields... I had to simply log in again with the login link at the top of the forum page, and use the back button (alt+leftarrow) several times until my reply was recovered so that I could preview, fix typos & submit..I searched the forum for "forum login timeout" and found one relevant post which appeared to say the only reason it's OP had a problem was do to making changes to his copy of firefox but that it was fixed ([solved]) without saying how he fixed it. There was a reference to using about:config which is beyond my skill level...How does one keep the from login session from timing out while one's browser still has an open window to what was a logged in forum page anyway
I have installed Dansguardian on my little brothers laptop (using Tinyproxy and Firehol too) and I have it mostly configured the way I like it. The only problem now is that I can't seem to block secure (https://www...) websites, and he knows a few proxies that use secure domains. I was wondering if anyone has been able to make Dansguardian block these websites or is it just not doable?
I have a proxy server (squid-3) that I would like to setup Dansguardian to do additional web filtering.
The system:
Ubuntu 10.10 - all updates as of today Dansguardian - 2.10.1.1-2ubuntu0.1 (latest update) Squid3 - latest update (not squid 2.7) Webmin - 1.530 (all updates) Webmin dansguardian module - 0.7.1
Ok - I have all of the above installed. When I go to the DG module page in Webmin, I get the following:
Warning - the version of DansGuardian you have is not supported by this Webmin module version Webmin Module Version 0.7.1 supports DG version 2.10 (& 2.9) Currently installed DG version
This obviously makes no sense, since I am running DG version 2.10.1...
PS. I have squid installed, but not configured (still tinkering) - could this be the problem? That squid needs to be running for DG to work?
I have installed dansguardian and squid on my home computer and I need to configure them. the only problem I couldn't find any manual only one for opensuse 9. And even there the part after "acl CONNECT method CONNECT" doesn't make any sense to me.
I have installed squid and dansguardian on my server, I also setup my iptables to forward port 80 communication to port 3128 (squid). I also have remove the comment on /etc/dansguardian/dansguardianf1.conf (line "bannedextensionlist") hoping that my server would block download. But it isn't, it still download file no matter I add in /etc/dansguardian/lists/bannedextensionlist. Oh yeah, I also add this line to my /etc/squid/squid.conf
I've been pulling my hair out and can't figure out what's wrong. I have dhcp, squid, and dansguardian all running on my server, but when I point a client to it for a proxy (192.168.1.15:8080) and try to get to a website, nothing happens and the connection times out. When I don't bother with the proxy, the client has no trouble getting to the internet. I've verified I can ping the server and gateway from both machines. And the services are running, no errors noted in the logs. Do I need to do any iptables or selinux changes?
My network is very basic, several clients on the same network as the server, connected to a verizon gateway. Local addresses are 192.168.1.x. The server is 192.168.1.15, gateway is 192.168.1.1.
installed dansguardian and now working fine.I got a small problem. People bypassing proxy settings in firefox, means they go to settings and changes proxy settings to no proxy.. how to prevent this? How can I force people to use proxy to connect Internet? I done some googling but, unable to find a solution.
