maybe the problem is in the squid.conf:

icap_service service_avi_req reqmod_precache icap://127.0.0.1:1344/squid_clamav bypass=off
adaptation_access service_avi_req allow all
icap_service service_avi_resp respmod_precache icap://127.0.0.1:1344/squid_clamav bypass=on
adaptation_access service_avi_resp allow all

and should be:

icap_service service_avi_req reqmod_precache icap://127.0.0.1:1344/squidclamav bypass=off
adaptation_access service_avi_req allow all
icap_service service_avi_resp respmod_precache icap://127.0.0.1:1344/squidclamav bypass=on
adaptation_access service_avi_resp allow all

Is there no solution to this problem ?

now it is working
i have installed pfsense from the scratch.
installing only squid-package (with dep)
activating claimav and it is working now (see attached squid.conf - file)

I wonder if snort or suricata breaks squid clamav or icap. The icap error occurs when i install snort and suricata but i dont know exactly if snort or suricata breaks it.

Same Here, have squid_clamav in the config.

is this a bug of the webgui Configurator?

I'had also Snort installed on my APU Board. do you think that snort can crash icap?

now I reinstalled my box from scratch again… no packeges installed and removed everthing from the XML... unsure, if i already should retry to install just squid...

Is there an update fix to this icap error ?

tohil

there is a comment in the icap package -> it is currently not mainainted. a volunteer is needed

genesislubrigas

if there is only a step by step procedure how to maintain it, i will volunteer.
