running squid and dansguarndian on a pogoplug for a home net

[iceman198]

My ultimate goal is to re-direct all internet traffic on my home network through my little arch linux box using squid and dansguardian.
I followed this gentleman's tutorial...it had it's hurtles but I got everything installed successfully. Now, I haven't done the last step of configuring my router just yet...as I wanted to use a PC (running windows), set Internet Explorer to use the proxy and make sure it works. Well...I can't seem to get it to work. Page just comes up as "cannot be displayed".
I'm hoping that it is just some simple setting that I need to tweak. The IP range on my network is 192.168.0.200 - 250...which I've reflected in my squid.conf. The IP of my arch linux (pogo plug) box is 192.168.0.222. Below are my squid.conf and dansguardian.conf. Any help would be greatly appreciated!
Oh, for testing, I've just been going into IE, tools, 'connections' tab, then into LAN Settings and checking the proxy box...putting in the IP of my pogo plug and port 8080. I've tried port 80...and 3128 as well...still can't load pages when I have the proxy set.
Do I need to change the proxyip in my dansguardian.conf?
Thanks again.

# Download Managers
# These handle downloads of files to be filtered and scanned.

# There are various methods possible but not all are included.
# The author does not have the time to write them all so I have
# included a plugin systam. Also, not all methods work with all
# browsers and clients. Specifically some fancy methods don't
# work with software that downloads updates. To solve this,
# each plugin can support a regular expression for matching
# the client's user-agent string, and lists of the mime types
# and extensions it should manage.
#
# Note that these are the matching methods provided by the base plugin
# code, and individual plugins may override or add to them.
# See the individual plugin conf files for supported options.

# one is forced to match as the default, regardless of user agent

# scanner. The plugins are run in the order you specify.

# Multiple plugins can be specified, and will be queried in order until one
# of them either finds a username or throws an error. For example, if Squid
# is configured with both NTLM and Basic auth enabled, and both the 'proxy-basic'

Če želimo uporabiti njegove storitve, moramo brskalnik prenastaviti s standardnih vrat 80 na vrata 8080. To bi morali narediti na vseh delovnih postajah.

# Preusmeri ves WWW promet z vrat 80 na vrata 8080

REDIRECT loc 8080 tcp www

Po tem popravku lahko brskalnik v krajevnem omrežju deluje na običajnih vratih 80, uporabniki pa nimajo nobenega stranskega izhoda mimo filtra, saj se ves spletni promet skozi preusmeritev odpelje naravnost v filter.

Thanks for the reply? So am I adding that line in the dansguardian.conf or squid.conf?

If you look the picture you see first layer is dansguardian:


Squid is just a caching proxy.

dansguardian.conf then.

But you have a bigger problem, because dansguardian doesnt respond to your request on port 8080 , which then forward request to squid on port 3128 and so on.

$this->bbcode_second_pass_quote('', '
')How it works DG

DG requires predpomnilnlik proxy ( proxy cache ) , which in our case is squid . By re-routing of TCP / IP door installation to create a sequence of processes , which is shown in Figure 6 The user sends a request for a web site (1 ) . The browser is configured to send requests to the doors of the 8080th At the transition the router port 80 is closed so that the user can not circumvent the prescribed route . DG, which listens on port 8080 , to request on port 3128 Process squid (2 ) . The latter request to the target Web server (3 ) and received a response (4 ) . Squid process to the DG side of the head ( 5 ) . DG verify that the MIME type or . file extension allowed ( 6 ) , namely sends the user a notification of refusal of the application. Squid sends the process of DG body site ( 7 ) . DG verifies the PICS if written on this site and the entire text of a page if it contains no banned words , terms , or if the weighted words on this page do not exceed the permissible limit ( 8 ) . If everything is in order , sends the contents of the user by him to the notice of rejection of the request ( and the explanation of why , if the DG is configured ) .

Thanks. That didn't seem to do the trick though. I added that line as the last line in my dansguarndian.conf...stopped and then restarted dansguardian...added in the proxy settings in IE....and still, page can't/won't display.

[iceman198]

Sorry, didn't see the last part of your reply...so basically, dansguardian doesn't seem to be talking to squid right?

supposedly, you could turn off dansguardian, and just use squid as a proxy...I tried that and still the same thing. In IE, i set the proxy IP and port to 3128....

Change loglevel = 2 to loglevel = 3 , do something with browser, then look what has been stored in DG / SQ log file.
Are both services DG / SQ up&running on your pogo ? "ps aux" command in terminal will tell you.

How do you imagine to use pogoplug as router ? It only has 1 nic.

proxyip should be ip address of router/proxy, something with more than 1 nic.

Here is the last few lines of my squid cache.log
$this->bbcode_second_pass_code('', '2014/02/14 15:38:42 kid1| ERROR: NF getsockopt(ORIGINAL_DST) failed on local=192.168.0.222:3128 remote=192.168.0.204:11618 FD 9 flags=33: (92) Protocol not available
')

Correct, the pogo plug has 1 nic, but I thought you could funnel traffic through it still...am I not thinking of things right?
