[squid-users] log problem
I have calamaris running on a daily basis, parsing the log files.
I have recently seen a problem with logging, I think since I updated to
ver. 3.2.x.
I see some weird characters on the "method" field, for example yesterday
the calamaris log had 2 lines with "non readable" chars on the method
column:
Incoming requests by method:
method request % Byte % sec kB/sec
--
GET 57420 95.16 5744092K 99.86 20 4.92
POST 2029 3.36 7202213 0.12 0 5.50
HEAD 646 1.07 228642 0.00 0 2.58
PUT 230 0.38 543536 0.01 14 0.16
NONE 12 0.02 50775 0.00 0 41320.80

ñµbc 1 0.00 3614 0.00 0 35292.97
I verified that these lines with weird chars where present in the squid
log file case by running the following command:
$ sudo cat access.log.0 | awk '{print $6}' | sort | uniq
��bc
GET
HEAD
NONE
POST
PUT
��S��S.D>�f�y�v��%
As can be seen there are 2 instances of "non-printing" characters on
field 6 of the log file. This means that squid in printing garbage on
field 6 (method).
Has anybody else seen this problem? Is this a (known and reported) bug?

Maybe somebody should make that (perfectly) clear in the wiki ... and maybe add an example on how to implement ICAP server. Well, now for the next question. Which ICAP server and how to implement? Can you help me? Regards, Clemente
[squid-users] Squid 3.1 youtube caching
I am running squid 3.1.9, and I would like to know if this version is able to cache youtube content? I did check the wiki (http://wiki.squid-cache.org/ConfigExamples/DynamicContent/YouTube) and I must say that it is not clear what bits applies to version 3.1. Can somebody give me some pointers to what exactly I should configure. Thanks, Clemente
[squid-users] Cisco switches and cache interception and TPROXY
I am in the process of upgrading our network infrastructure. At present I have a Cisco Router and I have a working interception cache (Squid) using WCCPv2 protocol for this purpose. In this upgrade process, I am considering the use of Cisco Catalyst 3560 or 3750 switches instead of the router, but from the documentation, these switches support WCCPv2 but the are some unsupported WCCP features. The WCCP features that are not supported in the software release 12.2(52)SE are: - Packet redirection on an outbound interface that is configured by using the "ip wccp redirect out" interface configuration command. This command is not supported. - The GRE forwarding method for packet redirection is not supported. - The hash assignment method for load balancing is not supported. - There is no SNMP support for WCCP. Taking in consideration these unsupported features would it be possible to: 1) use Squid in "interception" mode? 2) use Squid in "TProxy interception" mode? Clemente

[squid-users] config of squid to use external proxy
I want to config my transparent squid to use an external proxy (with user/password) authentication when accessing a specific set of sites. At present the situation is as follows: When I want to access a specific site, say www.example.com, I am required to set my browser proxy settings to use an external proxy, for instance proxy.external.com port 8080, and then I am required to enter a user and password. Basically the site www.example.com is only accessible through this proxy which is external to our site. On our site we have our own squid box configured as transparent cache (using WCCPv2), so what I would like is to be able to access www.example.com (transparently), i.e. without having to change my browser proxy settings. Can anybody help me with the squid config?

Actually it turned out that the server squid is running on could not access http://sandbox.tagle.it, not even ping the referred IP. After verification it seems that the problem is that the remote server (sandbox.tagle.it) is blocking the IP of our squid server.
[squid-users] Cannot access site - TCP_MISS/504
Setup: Squid-3.0-STABLE13 transparent proxy using WCCPv2 When I try to access the site the URL http://sandbox.tagle.it I get a time out message: --- The following error was encountered while trying to retrieve the URL: http://sandbox.tagle.it/ Connection to 72.27.230.81 failed.

What could be the problem?
[squid-users] wccp and Cisco router identifier
I am in the process of installing a "transparent" squid cache using wcpp using a Cisco Router C2600 (IOS Version 12.2(46a)) Everything is working fine except there is something that I don't know how to change. The Cisco router identifier is the address that is used for GRE on the router. Our router has two FastEthernet interfaces, each configured with an IP, and the router chose one of the IPs at random as the Cisco router identifier. How can that be changed? (i.e. how can I force the Cisco router identifier to be a specific IP) I searched in this list and somebody said to use a loopback interface on the Cisco, that it would much more predictable as the wccpv2 routerid is then always loopback id. How is this done? Clemente
