Any kind of information would be very valuable for me. 2.5 do run in Debian and so does squid 3. But I guess that the problem is that you might have forgotten to do some final configurations before starting squid. Have you checked that the user that is executing squid have vrite access to log directory and spool (cache) directory? Does those directories exist? Have you initialized the cache with squid -z command? If you aren't sure where the squid writes log files, where the spool directory is, and what is the squid user please specify them explicitely in the squid.conf.

RE: [squid-users] Blocking language/script
Is squid capable to block languages or scripts such as Java, javascript, etc... I have some users using Internet Explorer who suddenly can not use the Yahoo Webmail... i.e... since Yahoo!mail upgrade mailbox for their users, some of our users can not suddenly delete their mailbox, reply a post from Internet Explorer. I also, tried myself, using Konqueror (well, I think it was Konqueror) , and got the same problem. When switching to Galeon, I can use Yahoo Webmail without blockage... Is it squid that blocks languages and scripts? How to block/unblock langueges/scripts from squid? Squid can't do that, as it would involve opening and-going-into objects to alter content. That's not SQUID's business. Acl's can be mode to block on extension , mime type e.d; but squid can't or doesn't go as far as you want. M.
RE: [squid-users] redirect to a proxy
Hello, I've got 2 proxies SQUID 2.5, a principal and a secondary. All the traffics go to the principal, but i want to use the secondary if the principal has not connection to internet. For exemple : if the connection of the principal is down, a script changes the squid.conf in order to redirect the request to the secondary. That's kind of collisional what you formulate,since when squid is down, it won't be able to redirect requests either. We provide a master SQUID box and a backup box, using proxy configuration , in the browser to provide the backup squid box , as a fallback proxy cache for web access. M.

[squid-users] load balancing
greetings I have a new squid server i want to put in parallel with my existing system. i read most of the Docs and Faq's but still have not come up with a good understanding for my scenario. I'm running a transparent cache with squid guard. My problem seems to be How do I split my traffic ? or how do i create a failover if one squid server becomes to busy? here is my topology --[ L3 def route]---[ squid1]-- ---[squid2]-- right now i my problem is that I have only one default route option coming from my layer 3 device. therefore I cannot split my subnets and force 1/2 to one interface and the other half to another. I do have multiple cards in each squid box. DNS round robin won't work in this setup because i am forcing all unknown traffic to squid1. (correct me if I'm wrong) any advice? --- jeff donovan basd network operations (610) 807 5571 x41 AIM xtdonovan

[squid-users] squid on moderate scales
Hi, A friend of mine, a lab teacher, at a college is going to install squid on her college's Mandrake 10.0 official machine. She will use the default squid-2.5 Stable4 rpm cos' she is very new to unix. The problem is that there will be around 300 students using it as a proxy server plus around 25 teachers. Students will get access to a few sites and teachers to all. Now, my question is that will the default squid bundled in the OS be able to handle all the load? The machine is big, PIV 2Ghz with 1Gb swap and fast SCSI drives with 512Mb RAM (a gift from a leading computer company). This is the first time they are using a free OS in the college and I will be giving help from outside for squid.conf. Can someone share her/his experience with this load? The server will just have a caching dns and maybe a dhcp server with the same (not sure). Thanks a lot for the help in advance. With warm regards, -Payal
[squid-users] Weighted redundant proxy auto-config script.
For those who are interested, I have crafted a dynamic
Auto-Configuration script for use in Apache using Perl. Based on a
random number, it will provide a user with a listing of proxies which
may be weighted to determine their allocation.
Please see http://www.squid-cache.org/Doc/FAQ/FAQ-5.html#ss5.4
My script consists, basically, of two files--proxy.pac.pl and proxy;
the names are mostly arbitrary.
proxy.pac.pl:
#!/usr/bin/perl
if( $ENV{ SCRIPT_NAME } =~ /\.pac$/ ) {
print Content-type: application/x-ns-proxy-autoconfig\n;
} else {
print Content-type: text/html\n;
}
print \n;
my %proxy = (), $total = 0;
open A, proxy or die Can not access proxy list.\n;
while( A ) {
chomp;
/^(\S+)\s+(\S+)$/;
$proxy{ $1 } = $2;
}
foreach $p ( sort keys %proxy ) {
$total += $proxy{ $p };
}
$val = rand() * $total;
$last = 0;
foreach $p ( sort keys %proxy ) {
if( $val ( $proxy{ $p } + $last ) $val =$last ) {
$primary=$p;
push @list, $p;
} elsif( $val ( $proxy{ $p } + $last ) ) {
push @list, $p;
} elsif( $val =$last ) {
push @tail, $p;
}
$last += $proxy{ $p };
}
for( $i=0; $i=$#tail; $i++ ) {
push @list, $tail[ $i ];
}
print '
function FindProxyForURL(url, host)
{
if (isPlainHostName(host) ||
dnsDomainIs(host, .domain.com)
!localHostOrDomainIs(host, www.domain.com))
return DIRECT;
else
';
print ' return ';
for( $i=0; $i=$#list; $i++ ) {
print PROXY .$list[ $i ].:3128;
}
print '
DIRECT;
}
';
proxy:
proxy1.domain.com:8080 25
proxy2.domain.com:8081 75
The 'proxy' file simply contains proxy entries with a weight seperated
by a space. The weight value is arbitrary, the weights are added
together to determine the value to be randomized against.
I hope this proves useful to someone. As has been mentioned before
there are many other scripts for doing proxy selection. Please see

FD Usage is about 300, this way I guess that I have never more than 150 clients accessing the cache simultaneously. Works fine with a 5MBit adsl line, the only problem are huge downloads which I am unable to block. If you limit the site for most of the clients (i.e. the students) this will be no problem for your machine. Keep an eye on memory usage, i.e. don't make the cache_dirs to large. What is the uplink bandwith? Regards, Hendrik Voigtländer

See this 'df' : proxy2:~# df Filesystem 1k-blocks Used Available Use% Mounted on /dev/sda2 35518624269060 35249564 1% / /dev/sdb6 33032196432240 30921972 2% /usr/local/squid/var/logs /dev/sdc5 35001476 98692 33124796 1% /usr/local/squid/cache1 /dev/sdd5 35001476 1865408 31358080 6% /usr/local/squid/cache2 /dev/sde5 35001476 1859088 31364400 6% /usr/local/squid/cache3 Using this squid-server cache1 seems not to be used to write data to. When I change the order of the caches in squid.conf then the first listed in the conf-file will be 'ignored' to be used to save data to. So, i.e. when cache2 is listed first, then cache2 don't get data written to it. The filesystem-type in squid is UFS for all cache-dirs. I also have a proxy1 server that has been setup exactly the same and that server also shows the same issue. Any idea's ? Thanks in advance, John Dautzenberg

See this 'df' : proxy2:~# df Filesystem 1k-blocks Used Available Use% Mounted on /dev/sda2 35518624269060 35249564 1% / /dev/sdb6 33032196432240 30921972 2% /usr/local/squid/var/logs /dev/sdc5 35001476 98692 33124796 1% /usr/local/squid/cache1 /dev/sdd5 35001476 1865408 31358080 6% /usr/local/squid/cache2 /dev/sde5 35001476 1859088 31364400 6% /usr/local/squid/cache3 Using this squid-server cache1 seems not to be used to write data to. When I change the order of the caches in squid.conf then the first listed in the conf-file will be 'ignored' to be used to save data to. So, i.e. when cache2 is listed first, then cache2 don't get data written to it. The filesystem-type in squid is UFS for all cache-dirs. I also have a proxy1 server that has been setup exactly the same and that server also shows the same issue. Any idea's ? Thanks in advance, John Dautzenberg

[squid-users] Need to replace squid with more appropriat diagnositc program
A while back I had problems with running squid on a Cobalt RaQ XTR. Then I realized it had to do with how swap was triggered. Since squid actually has a setting that tells squid how much ram to swallow on startup it is a very good basic tester of available ram and swap funtion. I have been using squid like this but it is not perfect. For instance the reports and log files are not those of a diagnostic program. Can someone suggest a better alternative for testing ram and disk swapping. -- Josh Kuperman [EMAIL PROTECTED]

Not really...

RAM Test: memtest86 (on X86 type hardware only)
Swap test: the attached silly program could be useful..
General system health: Repeated Linux kernel compiles, in parallell to
stress VM system even more..

[squid-users] Random dropping of requests
Greetings, I have just taken charge of a squid machine that has been showing some strange behaviour for the last few weeks. For one thing, cpu usage on average is above 80% which seems abnormally high, even taking into account the high traffic (about 2000 hits per minute). Secondly, all traffic randomly stops for anywhere between a few seconds and 20 minutes. Restarting squid during this time brings it back up, but this isn't feasable when we have to do it a few times a day. Even if I don't restart manually, it becomes available again by itself, but the downtime is too costly. Now for some details. The hardware is as follows: 2.7GHz x 2 Xeon CPUs 2GB RAM 36GB x 2, 10,000 rpm SCSI drives One drive is used for the OS (Fedora Core 2, default kernel) while the other is used for cache (32GB cache size, reiserfs with notail and notime options). Next, until a few days ago, the machine was running Squid 2.5-STABLE6 (without patches). It was configured to use diskd and various options which I don't have availabe right at this minute. Quite a few OS settings recommended for Squid are present, such as port range (1024-65000), file descriptors (32768), tcp_max_syn_backlog (8192) etc. I tried switching to 2.5-STABLE5 with the 3 major patches since we have this setup on another proxy, but got the same results. This morning, I upgraded to the latest 2.5-STABLE6 version with all the current patches and set the cache type to aufs (simple 'squid -z', not a reformat of the underlying filesystem), but it solved neither the CPU usage issue, nor the random drops. Nothing unusual shows up in cache_log, access_log or any of the system logs. Our network monitor also confirms that this isn't a network issue and that requests are going to the proxy during the outages. Unless someone can identify the problem here, I'll consider installing Slackware and a custom kernel to rule out that it's an OS issue. Any help will be appreciated. Thanks, -- A.

I tried installing a new OS, newer/older version of squid and still had the same issue. I took the squid.conf during the high CPU load and commented out every ACL and basically allowed all to pass thru. I then turned on each ACL one at a time and found one of my ACLs was causing the CPU load. Not exactly sure why it caused the issue but all has been well for a week now. Regards, Scott
[squid-users] Authentication
Hello i works for a company which recently shifted to linux+squid, but we are getting a problem in the squid configuration- is there any way of authentication of squid proxy users without entering the username and password while accesing internet. We have developed a client module which can be used for authentication into server, i.e. the client module will ask for a username and password to access any services running by server, so can we do the proxy authentication by this client module OR can we develop any script wich can be run from workstations and can be used to authenticate the proxy users, the proxy authentication programm is samba. Please reply Thanks in advance __ Do you Yahoo!? Yahoo! Mail is new and improved - Check it out! http://promotions.yahoo.com/new_mail

Re: [squid-users] load balancing
LVS can be placed on the same server, but it is good if you a new Linux Box for it, I am not sure but last time I used it, I need to recompile the kernel. Please do check with the latest Docs. And why can not you do the Roundrobin. It is always a good option. And yeah most convinient, you can use a PAC file. --- Jeff Donovan [EMAIL PROTECTED] wrote: On Aug 2, 2004, at 9:25 AM, Henrik Nordstrom wrote: On Mon, 2 Aug 2004, Jeff Donovan wrote: I'm running a transparent cache with squid guard. My problem seems to be How do I split my traffic? This you do in your router in case of transparently intercepting proxies.. If you are not using a TCP interception device capable of tracking individual connections then this is most easily done by splitting the destination IP address space among the caches. CARP does so automatically for you. or how do i create a failover if one squid server becomes to busy? best done by an external load balancer. Linux Virtual Server is a good free one, highend routers switches usually also have reasonable load balancing functions built in. would this be a placed on a linux server in front of the two cache's or does it run on the same device as squid? Unfortunately my layer 3 switch does not allow for multiple default routes or even a policy route. Otherwise i would have just routed my traffic to the new interface. -j --- jeff donovan basd network operations (610) 807 5571 x41 AIM xtdonovan = Regards, Mohsin Khan CCNA ( Cisco Certified Network Associate 2.0 ) http://pk.aaghaz.net Happy is the one who can smile __ Do You Yahoo!?
