Topic: squid & MAC address to block web access

[steve]

Hi. I've seen the thread on limiting web access via iptables and MAC address, but does anyone know if the precompiled squid with SME5.5/5.6 was compiled using the --enable-arp-acl option? Thus I can limit web access by MAC address via squid.

I know I could just try it, but if anyone's done it before.....? would save me time!

thanks, -steve.

Check from the srpm files

I'll be happy for someone to prove me wrong, but I think the answer to this is no. arp acl option is not recognised when I try it out.

blocking by IP address and using proxy authentication seem to be only default options with squid on SME5.6 (authentication modules are in /usr/lib/squid)

will try the iptables.

Does anyone have any more news on this?

I'd like users to be able to access the SME box but not outside, preferably on a per ip or ip range.

Charlie,

I use Vincent's squid proxy rpm with a couple of templates added in to allow me to add in IP's that do not need authentication, so I set it to protected (auth on) and then do not allow any username/passwords access to the proxy, but add in those IP's I wish to have access without username/passwords, but I have not tested the custom addon templates on 5.6, only 5.5 so I dont know if they work for 5.6.

Also I do not have Vincent's 5.6 rpm, only 5.5 in my contribs.org contrib area, but you can try his site:

Thanks for that Cyrus - it looks like what I want, but I get the errors below.

I already have ProxyPass installed & Content Filtering (which I tried to get rid of but failed).

Could there be an obvious conflict?

Once again my thanks to you good people. I installed Spamassassin & ClamAV on two servers yesterday without a hitch & am shining in reflected glory. It's such a good way to learn Linux.

Charlie,

I am sorry but I have absolutly no clue as to what is causing your errors?

Are you using the right rpm for your version of SME, you need different versions for 5.5 and 5.6?

Other than re-downloading again to make sure you got a good copy I cannt think of anything else, and those error messages are greek to me, sorry!

[Abe Loveless]

Unfortunately, I know exactly what those errors are...  They're from an earlier version of the ProxyPass contrib, which accidentally dropped a file called index.php into the /etc/e-smith/templates-custom/squid/squid.conf/ directory.

Just delete that file, and re-expand the template

/sbin/e-smith/expand-template /etc/squid/squid.conf

And you should be all set.
