General :: Access Control Through Squid?

May 28, 2010

I'm using squid for proxy server in FC6. I'm also using squidGuard for web-site access restriction. I want to do some exception now for website access. For example, squid user1 with ip 192.168.7.10/32 shoud not access facebook.com while all other squid users with ip 192.168.7.11/32, 192.168.7.9/32 and so on... can access facebook.com since facebook.com is not listed in squidGuard .db files

Server :: User Name Based Access Control In Squid

Aug 20, 2010

I have configured squid proxy on centos 5.5 and some of my squid.conf file has following lines

Code:

http_access allow ncsa_users office

There are 3 users called "user034, user035 and user050" in the /etc/squid/squid_passwd file need to restricted access to internet except sites www.abc.com form anywhere in the lan. Once they logged in any ip, rule should apply.(that means no ip related acl, only user name related) How can I configure this in squid.

General :: LDAP Access Control For Users ?

Feb 16, 2010

I'm using Sun One LDAP server, (Soon to be moving to openldap). I have one Master server, no slaves, about 60 user accounts.

I'd like to add an attribute to each of the users DN's to restrict there ability to login to specific hostnames. I.e. I have hosts A, B and C. Dev staff can access A and B, but not C, and support staff need to access all of them.

I found a link at [url] which talked about using 'hostsallowedlogin' and 'hostsdeniedlogin' attributes but I'm presuming these are bespoke. If they are, how do you configure the ldap.conf to take note of these attributes when authorizing access?

General :: Squid Proxy Server For Web Access With Active Directory Authentication

Jan 28, 2010

I'm fairly new to Linux and very new to Squid and am having authentication issues! I am using Oracle Enterprise Linux (which is basically Red Hat without the branding) and wanting to use Squid Proxy Server for web access with authentication to Active Directory. I've found a number of articles about this online and all of them say to use auth program squid_ldap_conf which should be in /usr/lib/squid/. I don't have a squid directory in /usr/lib for starters and my squid binaries are in /etc/squid but there is no squid_ldap_conf in there either. I have installed the latest version of Squid (3.0) to see if that helped but I still cannot find the authorisation program.

Software :: Squid 3.0 Access List / Remove Redirect Statement From Iptables All Internet Access Is Blocked?

Jun 11, 2010

I have an old FC2 box running Squid version 2.5. It has been running since 2003 so I am in the process of replacing it. I have a new machine with FC11, iptables, and Squid 3.0 installed.

On the old machine I use iptables to intercept Port 80 traffic and send it to Squid. By default I block all internet access and allow only sites that are in an Allowed_Sites.txt file. Within Squid I also have statements to allow certain users to bypass Squid based on their IP address.

I have set up the same thing on the new box. I have iptables intercepting the Port 80 traffic and sending it to Squid. That is working because if I remove the redirect statement from iptables all internet access is blocked.

The problem I am having is that Squid is not blocking any websites. It acts like the ACL is set to http_access allow all. I have worked on this for several hours and am stumped.

These are my Squid rules:
acl allowed_sites url_regex "/etc/squid/Allowed_Sites.txt"
acl manager proto cache_object
acl localhost src 127.0.0.1/32
acl to_localhost dst 127.0.0.0/8 0.0.0.0/32
acl SSL_ports port 443
acl CONNECT method CONNECT
http_access allow manager localhost
http_access deny manager
http_access allow Bypass_Users
http_access deny !Safe_ports
http_access deny CONNECT !SSL_ports
acl our_networks src 192.168.1.0/24
http_access allow allowed_sites
http_access allow our_networks
http_access deny all
icp_access deny all
htcp_access deny all
http_port 192.168.1.254:3128 transparent
hierarchy_stoplist cgi-bin ?
access_log /var/log/squid/access.log squid
refresh_pattern ^ftp: 1440 20% 10080

refresh_pattern -i (/cgi-bin/|?) 0 0% 0

due to low disk space there arose a problem. Now I re-installed Debian along with winXP as dual boot. XP works as it was before. but i can't open Linux. When i select Debian on boot-select page, Debian starts but stuck at a point as shown below:

check root= boot arg cat/proc/cmd line
or missing modules,devices:cat/proc/modules ls/dev
ALERT!/dev/sda3/doesnot exist. Dropping to shell;

Enter 'Help' for a list of built-in commands.
/bin/sh: Can�t access tty; job control turned off.

i hv searched a lot but couldn't come up with a correct solution.i tried editing the grub by pressing 'e' when grub is displayed and added the line acpi=off irqpoll and then start booting. but the result was same.

General :: Transparent Squid - Iptables Syntax And Unable To Use Outlook To Access SMTP And POP3

Feb 10, 2011

I've set up Ubuntu 9.04 (desktop) at home in a lab environment (workgroup rather than domain) and have configured Squid. Everything works fine but, when I took it to the next level and made the proxy transparent, my problems began. I can still access sites (having pointed the XP Pro client to the squid box as the DG) and the sites are logged in /var/log/squid/access.log but I am unable to use Outlook to access my SMTP and POP3. I guess that the setup is blocking ports 25 and 110 and I'll need to configure iptables to forward packets destined for these ports directly to the "real" DG, rather than the Squid box. Here's the set up:

A single NIC (eth0) on 172.19.0.250 / 16 (static) ADSL router ("real" DG) on 172.19.0.1 I executed iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 80 -j REDIRECT --to-port 3128 My squid.conf:

Code:
acl all src all
acl manager proto cache_object
acl localhost src 127.0.0.1/32
acl to_localhost dst 127.0.0.0/8
acl localnet src 10.0.0.0/8# RFC1918 possible internal network
acl localnet src 172.16.0.0/12# RFC1918 possible internal network
acl mynet src 172.19.0.0/16

Server :: Squid Internet Access Getting Slower?

Jul 24, 2010

I've a SQUID proxy server installed in SUSE 9.0 ES server. I've created cache dirs on seperate partitions for better caching. Its working fine. But since last 15-20 days, i've experienced very slow net access to clients. I've gone through the /var/log/messeges file, it generates a two line error messeges

client read request fd602 invalid request
parse http request: unsupported method;HET

This messege increases as the number of clients increates (for internet access). The apperance of error messege lowering down as soon as the number of clients reduces.

As the count of clients increases error messeges increases, internet access getting slower and slower.
