Hi,
  to try the troubleshooting we need to know the version numbers. Can you post the output of the following commandapt-cache policy dansguardian ebox-squid squid
?

I have a similar problem and already report the problem as you can see at the following post.

http://forum.ebox-platform.com/index.php?topic=1301.0

I'm waiting for an answer from Javier too. I believe the problem is related with the firewall configuration, because firefox is showing a message that the proxy server refused the connection (when switching to Filter option in the General options). Also using zenmap the port used by squid appears open, then with the filter option the port is in state closed.

[Javier Amor Garcia]

Hello,
 i dont think that is a firewall problem. The last security update of dansguardian changed a lot of the syntax of configuration files and give us a lot of problems. I believed all issues were fixed but obviously is something left.

However I cannot reproduce your error, so I need more information about your conifguration.

First, I had to know if all of you have eithet the policy set to 'filter' or some object's policy set to filter.
Second, I need you to check if dansguardian is running with the command status ebox.dansguardian . If it is running plese wait some seconds and retry the command and check that the PID is the same. (to be sure that is not in a stop-start cycle).

If someone can send me a configuration backup of its ebox it would be helpful too.

[alfadaemon]

Hi Javier... Attached my conf backup

[Javier Amor Garcia]

Hi alfadaemon,
  i had looked your configuration and i dont find error in the squid/dansguardian section. I think that you were right when you suspected of firewall problems, can you try a 'accept' rule for http traffic?

[alfadaemon]

Javier, I believe that what it is needed is a rule to accept conections to the squid port configured at the General Settings in HTTP Proxy... will try out in a moment....

Nop.... it does not work, if you look carefully, I already have a rule for http traffic.

I'm running into an error like this where it continually says "Stopping dansguardian dansguardian, also, stopping squid http proxy squid.

Can't connect to it from remote, cant get onto the internet.

Tried rebooting, killing the process but stuck in a loop.

[Javier Amor Garcia]

coastdweller,
  that is that some error interferes with the normal start process of squid. To better diagnose it we will first stop those processes with the two following commands:

Code: [Select]

stop ebox.squid
stop ebox.dansguardian
After that we will execute squid and dansguardian manually to look for nay clue in the output:

To execute squid:  /usr/sbin/squid -D -sYC -N
To execute dansguradian: /usr/sbin/dansguardian -N

Hopefully the output will point out what is the exact problem, needless to say if you need it yo ucan paste the output here so we could diagnose it together

[javi]

Hi  coastdweller,

Could you also post the output of:

Code: [Select]

apt-cache policy ebox-squid
apt-cache policy ebox-dansguardian

Thanks

ebox-squid:

apt-cache policy ebox-dansguardian

When I have it installed it loops, as we use it locally to serve about a terabyte of archived data and a gateway I had to take a break from it (Hence the delay in my reply).

[javi]

apt-cache policy ebox-dansguardian
W: Unable to locate package ebox-dansguardian

That should be:

Code: [Select]

apt-cache policy dansguardian

alfademon,
 i forgot there is a error when dansguardian logs rotations, is fixed now but if you upgrade it may remain.
Please take a look to your /etc/logrotate.d/dansguardian and compare with it this. In case you have a different file copy it and restart the ebox-squid module.
