Begin by upgrading to a more current release. Current 2.7 is 2.7.STABLE9. But usually the cause to squid silently dying with no messages is that some of it's log files hit the magical 2GB barrier and your Squid is not compiled with large file support. This assuming you are NOT using the -C command line option which silences most crashes.. Regards Henrik
[squid-users] url-rewrite PHP script issue under Ubuntu 10.04
Hi !
I was wondering if someone else has noticed a similar behavior:
I wrote an URL-rewrite script with PHP as explained at
http://wiki.squid-cache.org/ConfigExamples/PhpRedirectors. The
script was running without complains under Squid 2.7.Stable9 and
Ubuntu 9.04, then I upgraded Ubuntu to 10.04 and warning messages
started to show up:
2010/05/15 16:48:28| WARNING: url_rewriter #XX (FD XX) exited
(repeat n-times)
2010/05/15 16:48:28| Too few url_rewriter processes are running
2010/05/15 16:48:28| Starting new helpers
Things I've tried to solve the issue without success:
- Simplified the PHP script to the minimum (finally just using the
wiki's example).
- A clean installation of Ubuntu 10.04.
- Downgraded PHP package from 5.3 to 5.2.
- Recompiled Squid (just in case).
Perl scripts are not afected, so I rewrited/transalted the script. The
service is up again but a big question mark was left over my head.
I know it's not a Squid's issue per se, but at least the wiki may need
to be updated before other people get stuck at this point...
Thanks for reading.

I know it's not a Squid's issue per se, but at least the wiki may need to be updated before other people get stuck at this point... Hi Horacio, Being a great PHP fan myself with a lot of helpers I've been fighting this problem for a year or so now. The issue centers around the automatic run timeouts PHP has. Under several of the 5.0-5.2 releases the background engine has either not obeyed the php.ini settings correctly or not obeyed run-time overrides correctly. I pushed through and supported many alterations to Squid-3.2 which help minimize the problem, but... As far as I can tell so far the new 5.3 engine seems not to obey either run-time or configured settings and sticks rigidly to a 60sec timeout. While technically helpers can be of any language, this recent behaviour change of PHP 5.3 makes it completely useless as a Squid helper for even small installations. I'd advise some other scripting language for now, or if you must the very latest squid-3.x code (http://www.squid-cache.org/Versions/v3/HEAD/) will be important to prevent Squid constantly restarting as its helpers self-destruct. Even then the constantly unavailable helpers make Squid a bit slow and hang on many requests while they are restarted. Amos
[squid-users] Squid + Tproxy + Bridge on Kernel 2.6.34 - Workaround
Hi, Squid + Tproxy + Bridge Setup on latest kernel - version 2.6.34 I had followed all the steps that had given in the http://wiki.squid-cache.org/Features/Tproxy4 Kernel - 2.6.34 iptable - 1.4.8 ebtable - 2.0.9-1 But clients were unable to browse and no errors in cache.log. Error - Network Unreachable. The error had returned by browser not squid proxy. Workaround :- After adding the following rules, clients are able to browse. # ip rule add dev device name fwmark 1 lookup 100 example # ip rule add dev eth0 fwmark 1 lookup 100 NOTE : Repeat the above for each interface except lo Source - https://lists.balabit.hu/pipermail/tproxy/2010-January/001212.html Based on the above source this issue had identified on kernel version - 2.6.32. But still not yet fixed. I have CC ed this mail to netfilter mailing lists also. Hope this helps Thanks, Senthil
[squid-users] Too many logon when auto redirect script
Hi All,
I have a Redhat ES 5.3 with squid verion 3.1.1. I also use the NCSA
authentication to control the user to access to the internet.
This box has been enabled a simple auto script for redirect namely
cace.pac on apache as the following:
function FindProxyForURL(url, host) {
if (dnsDomainIs( host,xx.com))
return DIRECT;
if (url.substring(0, 5) == http: ||
url.substring(0, 6) == https:||
url.substring(0, 4) == ftp:)
return PROXY proxy..com; DIRECT;
}
When the user set directly to proxy.xxx.com at browser, squid asked
for the user/password for only one timm of new session. However, if
the user set at browser and point to auto redirect script, the brower
aske to many pop up for entering user name and password for new
session.For example, the squid ask to enter the password for
google.com as 2 time, Another website is 3-4 time.
Any help would be appreciated.
Regards and Thanks
