Re: [squid-users] uninteruptable proxy
Hi, Consider using VMware ESX/ESXi 4.0 and FT. I have successfully used, tested and demonstrated VMware ESX/ESXi 4.0 and VMware FT services performing web scanning and proxy services. In the demonstration simply pull the power plug or "reboot" one of the ESX/ESXi servers. The time to switch to the secondary system was in the ms range - many times simply pinging the devices the switch was not detectable. In each test - all sessions remained active - including download of data / files such as ISO images, or streaming video. Each server running Squid was CentOS based, running latest kernel, including VMware tools. At the time I was using Squid 3.0 (exact version I cant recall, but it should not matter). Let me know if you need any further information.

Re: [squid-users] uninteruptable proxy
peoples in my organization do online bidding, and if browsing interrupt/disconnect for any reason(e.g hardware failure) and restore within a 50 or 60 seconds.. their session terminate/disconnect, and they lost. I think with any normal proxy server if the client terminates a session or times out the proxy, too, will terminate the session. I suspect you are using the wrong terminology: what you need is not a highly available proxy service, i.e. a proxy suited to heavy load and with a very low downtime, rather a _persistent_ proxy. I'm not sure whether that's the exact industry term but I'm pretty convinced "highly available proxy" is not what you need. If anyone here can tell you about a persistent proxy--that is, a proxy that keeps track of sessions and keeps them alive even if clients time out--then you'll be golden. I for one don't have knowledge of such software. --On Saturday, January 02, 2010 11:22 +0500 Muhammad Sharfuddin wrote: peoples in my organization do online bidding, and if browsing interrupt/disconnect for any reason(e.g hardware failure) and restore within a 50 or 60 seconds.. their session terminate/disconnect, and they lost. we need uninteruptable web/proxy services. we need Highly Available Proxy Infrastructure/Services what are the possible solutions does following are the options 1, Clustering Squid (I think session will break) 2, Clustering two virtual machines, and virtual machines are running Squid, so if one host machine downs/crash, the other host machine continue running squid (I think in this case, session wont break, because the other host machine will run the same squid) please suggest/recommend Regards --ms
Re: [squid-users] report of subdomains

If that isn't quite what you want, you could probably hack up one of the other scripts to include the top- and second-level domain name instead of just the top. We used to use Calamaris, but have since switched to an in-house script that provides much of the same functionality. The 2nd-level domain report is one of our staples...

[squid-users] squid transparent proxy setup
Hi everyone, I'm currently attempt to setup a transparent proxy between my linksys router and my wifi access point. The hardware setup like the following Linksys Router --> Ubuntu PC (2 Network Card) --> switch --> Access Point --> Laptop On the Ubuntu PC, eth0 is connected to the router, eth1 is connected to the switch I've read on how to setup transparent proxy using squid and seems to done all setting properly. When I was about to test it, it realize that 1) eth1 doesn't have an IP 2) Computer connected to access point cannot obtain IP address So as of this point, I can not test to see if my transparent proxy is working or not. So here are my questions 1) How do I make the laptop that's connected to the access point obtaining IP address from router? Do I need to setup DHCP service on Ubuntu PC and give a different IP range? 2) Do I set a static IP for eth1? If I do, should I setup the static IP in the same range as eth0? (eth0 now is 192.168.1.0/24, should I setup eth1 within 192.168.1.0/24 or some other IP range like 192.168.200.0/24) 3) On my Ubuntu box there is only Apache Server and Squid2 are installed, am I missing any applications?

What standard things would it do? Generally I start exploring and have to code ad hoc stuff with sed, awk, and grep in a bash script or maybe use perl. Somone may have a collection of scripts to share., that is all I have ever used. I guess you could get a DB import tool and then use whatever report generators exist, that seems to be a popular approach these days. > > Tnxs in advance. > _ Hotmail: Powerful Free email with security by Microsoft. http://clk.atdmt.com/GBL/go/171222986/direct/01/
[squid-users] "Homeserver", quest for review
Hi, I'm planning to set up squid (2.7-STABLE7) on a small homeserver, which is responsible for max. 4 people. The machine has 8GB RAM and the squid cache_dir will reside on a second harddisk with 30GB space. This is what I've planned to configure: cache_mem 512 MB maximum_object_size_in_memory 10 MB memory_replacement_policy heap GDSF cache_replacement_policy heap LFUDA minimum_object_size 0 KB maximum_object_size 1 GB cache_dir coss /var/cache/squid/c1 10240 max-size=3145728 block-size=4096 maxfullbufs=10 cache_dir aufs /var/cache/squid/cacheA 16000 64 256 Sounds this reasonable, did I overlook something, or is all this just crap? Any thoughts? Thanks, Heinz.
