How to configure HAVP

LiquiD_85

Same damned problem, it's hard to belive really!! Restarted pfsense and havp.inc rollback to defaults values, changed MAXSCANSIZE to 5000000 and KEEPBACKBUFFER to 600 and mdconfig to 16MB, saved file and tried … still the same! I've tried also with MAXSCANSIZE to 5000 and 5, nothing changed!!!
I think something happen to my pfsense installation, tomorrow i'll try with a fresh installation!

After save config you must call from shell for reload config
killall havp
havp

Finally this wonderfull tool works fine, i'm going to explain my tests:

New installation in a new machine, installed HAVP and set Max download size and Scan max file size in Services -> HTTP Antivirus to 100
and it's doesn't work .. I've changed MAXSCANSIZE and KEEPBACKBUFFER to 5000 and 600 saved and in Diagnostics -> Command i've executed killall havp and havp .. and it's doesen't work … NOW i've changed "Max download size" and "Scan max file size" to empty and it's work like a charm, so i understand that the "secret" was the SAVE button in Services -> HTTP Antivirus ..

Now i've removed and reinstalled HAVP, set MAXSCANSIZE to 5000 saved and went to Services -> HTTP Antivirus and pressed SAVE, it's work perfectly!!! I think HAVP do not scan files bigger then 5K with MAXSCANSIZE=5000 and for me it's ok!!!

I think also that in Diagnostics -> Command "killall havp" and "havp" do not make the changes effective, or maybe i'm wrong, i don't know, i hope that my experience will help some people that have same problem!!!

Thanks a lot to all!!! :D

I test different configurations Need set MAXSCANSIZE to any not-empty (and not 0) value
I use 5000000.
This possible set via gui and all work.

LiquiD_85

Yes MAXSCANSIZE in the havp.inc file is now 5000 and i've never set it to 0 or empty!!
In the gui now i've checked only Enabled and Use external interface, and it's work like a charm!!!

Use different ports to HAVP and squid
squid = 3128
havp = 3125

Via GUI Squid custom options add
cache_peer 127.0.0.1 parent 3121 7 no-query
and disable squid GUI parent proxy options

I think we have the same/similar problem.

Squid and squidguard work. Havp works. But not together with havp as the parent proxy. We get

havp[22448]: (127.0.0.1) Invalid request from browser

when the above cache peer line is used.

Any more clues on what to try as I am now totally confused.

Post pls you havp config, squid 'cutom options' and 'upstream proxy' options

andrew0401

Upstream proxy - blank - not used

Custom

redirect_program /usr/local/bin/squidGuard -c /usr/local/etc/squidGuard/squidGuard.conf;redirector_bypass on;redirect_children 3;cache_peer 127.0.0.1 parent 3121 7 no

HAVP is now logging most entries to syslog - about 1 in 10 are either "could not send body to browser" or "Inavlid request from browser".

But Eicar test comes through no problem! I seem to either have havp working in isolation or as a parent proxy and it stops scanning.

Confused

cache_peer 127.0.0.1 parent 3121 7 no-query

havp mast have port 3121

andrew0401

havp is on 3121

also just realised that whilst havp is working as much as logging some (but not all reuests), squidguard and lightsquid have both stopped working!

At this stage not impressed with havp

Andrew

andrew0401

As suspected - removed Havp and lightsquid and squidguard started working again.

Has anyone managed to get this group of packages to work together and if so how?

HowTo use squid & HAVP

Scheme: {inet}->[HAVP]->[Squid cache]->{clients}

HAVP:

'Use external proxy interface' disable
'Proxy port' - select HAVP-proxy-port, different from the squid-proxy-port
'Parent proxy' leave empty

Squid:

disable upstream proxy
custom options Add (here 3121 - havp proxy port, change to you self)

cache_peer 127.0.0.1 parent 3121 7 no-query

(do not delete exists options)
