ICAP mode: DENIED : Could not perform content scan!

[MarkusPL]

Hi,

I set up  E2G as an ICAP for Squid. In general it works really fine. Today for some reason E2G couldn't perform content scan and it sent a DENIED response to the Squid with message:

*DENIED* ICAP Response filtering: WARNING: Could not perform content scan!

my question is:  how to configure E2G  so that it responds with ACCEPT in such a case 

(I mean if it's impossible to perform the content scan)

the problem is kinda serious, because if that happens the whole company can't browse the internet :)

thx for any hints

markus.

This error is associated with using a virus scanning plug-in.  

Please look in system log to get more details of the error cause.

If there is the error "Unknown return code from content scanner:" then this can be bypassed by setting "disablecontentscanerror = on" in your e2guardianfN.conf files.

This is clearly documented in the 'AV_SCANNERS' section of the example e2guardianf1.conf file.

#disablecontentscanerror = off
#
# Disable content scanning with error (timeout, AV crash, etc)
# If you enable this option you will allow object with an unexpected result
# Content scanning primarily is AV scanning (if enabled) but could include
# other types.
# With "on" you can allow INFECTED objects
# (on|off) default = off. (default and highly recommended)

If there is the error "scanFile/Memory returned error: NNNN" then either investigate why the virus scan engine you are using is returning the the unexpected error code NNNN and fix that, or turn off the virus scanning.

Regards

Philip
