Posted in Tutorials by tux 1 Comment. The procedure below was tested successfully on Cent. OS. The same thing was also implemented on my BSD box and works as well. Squid is a caching proxy for the Web supporting HTTP, HTTPS, FTP, and more. It reduces bandwidth and improves response times by caching and reusing frequently requested web pages. Squid has extensive access controls and makes a great server accelerator. Ubuntu 17. 10 documentation covers information on how to install the operating system in a virtual machine. Im posting this to hopefully helpout anyone else who might encounter this. I have a Win2008r2 domain, and my clients decided to stop talking to the WSUS server. This article describes how to configure a vacation autoresponder in Postfix mail server so email senders can be informed when the recipient is not available. It runs on Unix and Windows and is licensed under the GNU GPL. Squid provides with the best possible web access. Squid optimises the data flow between client and server to improve performance and caches frequently used content to save bandwidth. Squid can also route content requests to servers in a wide variety of ways to build cache server hierarchies which optimise network throughput. QUICK TIP 1. The easiest way to install and configure Squid Proxy is to install it via the distro package e. RPM. deb. tgz then install webmin for easy configuration of ACL and proxy restrictions. Use SARG or Squid Report Generator for log analysis. Most logical way to configure ACL is to have a list of Allowed Sites then deny All, so no need to create a Restricted Sites thats difficult to manage. Meaning only sites set in Allowed sites can be access by a group, the rest is denied. The squid has some limitations, if you want content web filtering, I recommend Dansguardian. Internet sites access can be controlled by IP address or subnet, just make sure you know some basic subnetting 6. TCP port familiarization is also a helpful skill in squid configuration. If you want more flexible and more advance, you can try to use LDAP to authenticate Squid proxy users. SOFTWARE REQUIREMENTSAny Linux or BSD distribution Cent.

One of the important things in the squid. The directories specified there must be created in the same path and with exact space as mentioned in the conf file with 7. In the config file, edit the following lines these are current config of squid proxy HTTPPORTThis parameter allows the user to define the address on which Squid will listen for clients http requests. This is a required parameter, and there are no defaults. Without this configuration, Squid will never start. Check httpport, 3. CACHEMEMSpecifies the ideal amount of memory to be used for Hot Objects Negative Cached objects In Transit objectscachemem 1. MBMAXIMUMOBJECTSIZEObjects larger than this size will NOT be saved on disk. The value is specified in kilobytes, and the default is 4. MB. If you wish to get a high BYTES hit ratio, you should probably increase this one 3. MB object hit counts for 3. KB hits. Leave this value low if you wish to increase the speed more than what you want to save bandwidth. Note If using the LFUDA replacement policy you should increase this value to maximize the byte hit rate improvement of LFUDA See replacementpolicy below for a discussion of this policy. KBCACHEDIRAll objects which are to be cached are stored in the disk space defined by this tag. This defines the path to cache directory, cache directory name, type and size of the cache area. Set cachedir to an area that has a large amount of hard disk space in order to devote to caching. CACHEACCESSLOGAll the activities the client does gets logged in this file. Using this, analysis on the access made by the clients can be done. Customization of the logging can be done using the acls which logs only those clauses in the specified logformat. If no acl is specified, all requests will be logged to this file. To disable logging of a request specify none. Logs the client request activityCACHELOGThis defines the path and the file where general information about your caches behavior goes. This file contains startup configuration information, as well as assorted error information during Squids operation. This file is a good place to look when a website is found to have problems running through the web cache. Entries here may point towards a potential solution. Cache logging file. This is where general information about your caches behavior goes. CACHESTORELOGThis tag defines the location where the transaction log of all objects that are stored in the object store, as well as the time when the object get deleted. This file really doesnt have very much use on a production cache, and it primarily recommended for use in debugging. Therefore, it can be turned off by entering none in the entry field. Logs the activities of the storage managerACCESS CONTROL LISTSYou can limit users ability to browse the Internet with access control lists ACLs. Each ACL line defines a particular type of activity, such as an access time or source network, they are then linked to an httpaccess statement that tells Squid whether or not to deny or allow traffic that matches the ACL. Squid matches each Web access request it receives by checking the httpaccess list from top to bottom. If it finds a match, it enforces the allow or deny statement and stops reading further. You have to be careful not to place a deny statement in the list that blocks a similar allow statement below it. The final httpaccess statement denies everything, so it is best to place new httpaccess statements above it. Note The very last httpaccess statement in the squid. You therefore have to add your specific permit statements above this line. In the chapters examples, Ive suggested that you place your statements at the top of the httpaccess list for the sake of manageability, but you can put them anywhere in the section above that last line. Squid has a minimum required set of ACL statements in the ACCESSCONTROL section of the squid. It is best to put new customized entries right after this list to make the file easier to read. Here are the following ACL created in squid. SSLports port 4. Allowed. Sites dstdomain usrlocaletcallowed sites. Restricted. Sites dstdomain usrlocaletcrestricted sites. Safeports port 8. Safeports port 2. Safeports port 4. Safeports port 7. Safeports port 2. Safeports port 1. Safeports port 2. Safeports port 4. Safeports port 5. Safeports port 7. CONNECT method CONNECTHTTPACCESSThis is used for filtering based on the acl matchings.
