Description David Walser 2021-10-04 17:15:46 CEST
Squid has issued an advisory on October 3:

The issue is fixed upstream in 4.17.
Comment 2 David Walser 2021-10-04 17:40:14 CEST
The issue is also fixed in 5.2, which doesn't build in Cauldron due to an issue with openssl 3.0.0:

Hello, friends. :)
Sorry to interfere with your "squid" update process. Since squid-4.17 is in your testing, I did not create a separate topic. Especially since all squids (4.13-4.17) work fine, including in HTTPS filtering mode, but there is such a thing in packages:

urpme squid

deleted squid-4.17-1.mga8.x86_64
error reading information about the service squid: No such file or directory
error: %preun(squid-4.17-1.mga8.x86_64) scriptlet failed, exit status 1
ERROR: 'script' failed for squid-4.17-1.mga8.x86_64
error: squid-4.17-1.mga8.x86_64: erasing failed

You can only delete a package using the "Marquis de Sade" method: rpm -e --noscripts squid

The reason is here:
%_preun_service squid
if [ $1 = 0 ] ; then
	rm -f %{_logdir}/squid/*
#        /sbin/chkconfig --del squid # The package is not being deleted because of this line!

Could you additionally fix the package removal process? And one more question, if possible: why is there no "sarg" in the repositories? Thanks.

Comment 9 David Walser 2021-10-10 17:55:33 CEST
Thanks, line removed from SPEC in SVN, will be fixed by the next update.

sarg is a long-since dead project and has been replaced by squidanalyzer.
Comment 10 Alex Kotov 2021-10-10 19:18:17 CEST
Hi, David. I haven't set up squid for a long time, probably since sarg was relevant. )) But I have an urgent job for tomorrow, so I was at a loss with the choice of a log analyzer. Now I'll try to screw squidanalyzer. Thanks a lot for the advice.

Comment 11 Alex Kotov 2021-10-10 20:38:17 CEST
Created attachment 12944 [details]

@David Walser

Very, very good! I think that the client will be delighted: a large pile of graphs, tables by users. It is similar to Sarg, but feels a little cooler (screenshot in attachment). Possible, in squidanalyzer is clearly missing a file:


Alias /squidreport /var/www/html/squidanalyzer
        <Directory /var/www/html/squidanalyzer>
            Options Indexes FollowSymLinks
            AllowOverride None
            Order deny,allow
            Deny from all
            Allow from

Sarg had an initial node config, but these are small things. Thanks again, David. :)

Best regards,
Comment 12 David Walser 2021-10-10 20:57:31 CEST
Yeah it's more modern and efficient than sarg.  Your extra file is completely unnecessary.

No installation issues.

Hmmm, something fishy with the  default installation.

When I now set localhost port 3128 as proxy in Firefox and restart Firefox, I don't get the Google page as default, instead I get the message "Firefox connects to a proxy which refuses connetions". And more: I have on Firefox a second home page which is http://madb.mageia.org/tools/updates, and that one displays OK. But as soon as I try to open one of the bugs, I get the same message as above.

Comment 15 Hugues Detavernier 2021-10-12 17:19:13 CEST

have you tried to set IP address instead of localhost?
I don't have problems with IP Address.
Comment 17 Bruno Cornec 2021-10-25 00:21:36 CEST
Is there still something preventing the release of 4.17 ?
Comment 18 David Walser 2021-10-25 00:29:53 CEST
Someone in QA needs to validate it.
Comment 19 Bruno Cornec 2021-10-25 00:37:00 CEST
Wasn't comment 13 enough ?
Comment 20 David Walser 2021-10-25 00:49:41 CEST
(In reply to Bruno Cornec from comment #19)
> Wasn't comment 13 enough ?

In my opinion, yes, I agree with you.
Comment 21 Alex Kotov 2021-10-26 22:45:53 CEST
@David Walser
By the way, squid-5.2-1.mga9.x86_64.rpm (Mageia-9) works fine. I made a "Bastion" on it for myself - an gateway-filter: https://github.com/AKotov-dev/bastion And an installation flash drive (IceWM-M9), so as not to waste time on deployment: https://drive.google.com/drive/folders/16xwTUpQzTASXkzXvCFaoQqByXgvP1XaE?usp=sharing 

I'll leave them here, maybe it will be useful to someone for experiments or squids testing.

p.s. I wonder how soon black smoke will come out of the server if 500+ users are connected through it. ))

With best wishes,

Comment 14 makes me uneasy, but sending this on, based on this opinion.

Validating. Needs an advisory.
