You may be able to acheive something along these lines by configuring Squid to use a non-ICP parent (no-query no-cache-digests no-netdb-exchanges cache_peer options) and "prefer_direct on".

Hi, thanks to both of you, Henrik and vda(?), for being so patient with me. ;) [EMAIL PROTECTED] wrote: - you can block other programs like icq. Only way of really blocking things like icq I can think of is by changing dns resolution for these hosts. simply done on the proxy server and not for the whole network. Doable with iptables (block by port#) Not that easy... You can configure icq to use nearly any port connecting to their login servers, and ICQ will try them all out for you... ;) So if you have any open port through your firewall chance is big that icq works. What can you do against someone plugging into your intranet a preconfigured laptop which will NOT ask novell about anything before going direct? That's right, sure. But we usually do not allow anyone or any ip address to go directly. In this case here we allowed this to test with and without proxy. Ok, here is what we did so that we cannot reproduce the error anymore. The images of our application are loaded by javascript and switched from visible to invisible and back again. But there seemed to be a mistake so that every image was requested again and again by the browser though it should not. Just the navigator part had about 50 imgaes loaded on every click.

[squid-users] Squid optimize settings
Hi, It's fairly easy to optimize: Re-compiled squid to handle 8192 filehandles, we ran into problems there after a while. Settings in squid.conf dns_children 32 cache_dir aufs /var/cache/cacheA 1000 16 256 cache_mem 450 MB Now use as much cache_mem as you can, that really makes a difference. Don't use all your memory for caching. I remember reading you should use half of your free memory but I can't remember on what site I read that. We're using a very small cache_dir as we also have a second cache on the outside of our firewall. There is where we have our major cache_dir. cache_dir aufs /cache/cacheA 16000 32 256 cache_dir aufs /cache/cacheB 16000 32 256 cache_dir aufs /var/cache/cacheC 14000 32 256 Our filesystem is EXT3, as far as I read it's better to use ReiserFS altho people differ on that as well. I'm sure there are more things we could do but nobody is complaining anymore and the effort of optimizing the last few bits and bytes isn't worth it. Besides, like i said earlier it seems like our line speed is holding us back more as squid is at the moment. In follow-up to Henrik's mail: We used diskd at first but afer switchting to aufs the system became more stable. We are not running the cache on a separate drive but that would surely make a difference. The first implementation of the linux system could have been better, if we would have set up a new squid machine we would make that change as well. Greetings Peter

If the client is working properly then there should only be 2 connections per client. The default setting is to only open 2 connections but if you have installed a download accelerator or similar software which reconfigured these settings of the browser, or if your browser is buggy, then there may be very many connections initiated, up to one per image concurrently requested.

The general recommendation is to not use very much cache_mem with the exception if your are running a reverse proxy/accelerator.

It is alway good to select the proper hardware for the job. Most people setting up their first Squid go with hardware suitable for a normal fileserver has somewhat different requirements than Squid. For a high performance Squid you want * A single fast CPU. SMP is not of any use for Squid. * Several harddrives. The seek time is the first bottleneck you will run into and the most cost effective way of optimizing seek time is to add more harddrives (two drives seek twice as fast as one). * No RAID for the cache drives. Certainly not RAID5. But with a good RAID controller there is no problem from the RAID until you reach around 150-200 req/s on a 5-drive RAID5. * Plenty of memory as per the memory usage guidelines in the FAQ. Note: There is a upper limit on how large Squid you can build on most hardware. It is not practical to plan a Squid where the Squid memory usage will go above 2 GB. But at the same time there is no noticeable benefits in cache hit ratio in storing more than 1 weeks worth of content so this limitation isn't really a problem assuming one is willing to accept that the harddrives may be too large and can not be fully used. Regards Henrik

[squid-users] Problem with ACLs and access
First, I've read the FAQ and searched this list and tried various incantations of the configuration, below, but it simply isn't doing what I expect. What I want to do is to allow access from two networks: 172.16.0.0/22 (split subnet) 172.26.9.75-172.26.9.100/32 Deny access to 172.16.19.246. Deny access to everyone else. my acls are: acl all src 0.0.0.0/0.0.0.0 acl nw1 src 172.16.0.0/22 acl nw2 src 172.26.9.75-172.26.9.100/32 acl block src 172.16.19.246/32 and http_access deny block http_access allow nw1 http_access allow nw2 http_access deny all But instead of having the desired effect, I seem to be blocking all access. This is squid-2.5-STABLE4. Thanks in advance. Sean McLinden Allegheny County Health Department

Changing debug_options probably won't help. The best way to debug this is to make sure Squid can leave a coredump file and then use gdb to get a stack trace. See http://www.squid-cache.org/Doc/FAQ/FAQ-11.html#ss11.19 and/or Chapter 16 of Squid: The Definitive Guide. Duane W.

[squid-users] Squid Performance Analysis
For several years, I've used Webalizer to generate periodic web reports detailing Squid activity and the crufty, old NLANR scripts to generate extremely plain weekly reports. Both Webalizer and NLANR generate reports from the client perspective. I have a requirement to generate a different report. One that answers the question: "What bandwidth would we have used had we not installed a Squid proxy?" If possible, this needs to be generated from the standard Squid access log. Is there something that analyzes the various "*_HIT" statuses in the log and produces a "what might have been report"? Does anyone know of any tools that are not listed on the Squid Cache web site that would provide this type of report?

Have you tried Calamaris?

The ISP generates exactly the same message for any filtered page. You may be able to acheive something along these lines by configuring Squid to use a non-ICP parent (no-query no-cache-digests no-netdb-exchanges cache_peer options) and "prefer_direct on".

You can configure things in this manner, but not for doing what you ask for. A sibling will not get any traffic unless it has clients of it's own. Requests are only forwarded to a sibling if the sibling reports it already have the requested object cached. You can set it up as a parent however. > This helps me to do whatever modification I need in future without > messing a lot with the main cache server.
