Hi,
I would like to ask you is there a way to configure squid to redirect IPs. I want squid to read IP's from file saved in .TXT format saved on HDD or server on internet. And when user's IP matches with the IP from the TXT file squid redirects it to external URL hosted on remote server.
Second question - is there a way to configure squid to read the external TXT file every 10 minutes for example so when I manually enter new IP or remove old one squid reads it and reconfigure itself.

Regards

Hi, Welcome to LQ.

LQ has a fantastic new search function,

This may save you valuable time waiting for a reply... :-)

Here are 2 web pages that have helped me, although I have not done what you require doing,

You can use redirectors like squidguard.
Every connection will force squid to read the config file(acls) so if the TXT file is linked to a certain acl, then it will be read everytime a coonnection is attempted, so you dont need to manually force squid to read it any other time.

I thought that squid reads squid.conf only when it starts and it keeps a copy from that squid.conf file to the RAM memory. I think that reading from HDD every time when packet passes the squid server is too slow process and will be a bottleneck.

So if I do this


acl acl_allow src "192.168.2.2/squid/client_allow.txt"
acl acl_deny src "192.168.2.2/squid/client_deny.txt"

http_access deny acl_deny
http_access allow acl_allow

(keeping the .TXT file on another server) eventually will be a too slow process because for every packet squid must connect to the server where its hosted the .txt file.

Am I right?

not for every packet, but for every client's initial connection to the squid server.
What you intend to de is usually all handled by a redirector like squidguard. you can then configure in squidguard, the time filter, which will be checked on every connection

I know that PHP can pass IPs with .TXT file. Is there other more efficient way to pass IPs from the PHP program to the squid server?

rcbandit, you may search (and read) the manual and or wiki, (the links above, hint, hint)

it will/should answer these questions,

if you have problems with the setup we may be able to help you further.

as far as I know, these files will be cached for each instance,

if they're not too large (how large are the files?) they should not cause concern.

Squid is meant to speed up web access by caching the parts of pages that don't change too often.

If the filter files are really large then there may be a better application to do the filtering on a server.

As mentioned above, squidguard and calimaris comes to mind (foss)

squid can do basic filtering and more, but you may find other tools that enable you to manage it easier(gui, search...)

I have been using squid for about 5 years and rarely have trouble. (ver3)

But I don't use a filter, all adults here on my gigantic 2 pc network (lol).

Cheers, please let us know how you go and how you got it to work.

Hi,
I have news - my friend advice me to use LDAP - PHP writes the IPs to LDAP and squid reads them. Is it possible to do it?

Hi, I'm sorry But I don't know about ldap and php.

regards, Glenn

Its quite possible, you can use squid_ldap_auth module/helper and then you filter your users according to ips, but neads extra care on filtering.
