Installation
|
||
|
|
------------
|
||
|
|
|
||
|
|
First of all, you have to install the c-icap plugin (os-cicap) from the plugins view.
|
||
|
|
|
||
|
|
.. image:: ../images/menu_plugins.png
|
||
|
|
|
||
|
|
|
||
|
|
After a page reload you will get a new menu entry under services for C-ICAP.
|
||
|
|
Select it and you will get to the following screen:

General Settings
|

|
||
|
|
|
||
|
|
:Enable c-icap service:
|
||
|
|
Enable the C-ICAP service to handle ICAP requests.
|
||
|
|
:Timeout:
|
||
|
|
The time after which the socket will be closed.
|
||
|
|
:Max keepalive timeout:
|
||
|
|
The time after which the socket will be closed if it stays inactive.
|
||
|
|
:Start servers:
|
||
|
|
The count of the server processes which will be spawned.
|
||
|
|
:Max servers:
|
||
|
|
Limit the count of processes
|
||
|
|
:Listen address:
|
||
|
|
The address in which the server should be bound.
|
||
|
|
This address is usually the loopback address (\:\:1 for IPv6 or
|
||
|
|
127.0.0.1 for IPv4). The default value is \:\:1.
|
||
|
|
:Server admin:
|
||
|
|
This field should be set to an email address which acts as a contact
|
||
|
|
for users, who are having issues with the server.
|
||
|
|
A good idea would be an address, which converts the mails to your internal
|
||
|
|
ticket system.
|
||
|
|
:Servername:
|
||
|
|
If you want to override the server name (displayed on error pages),
|
||
|
|
you can enter it here.

:Enable ClamAV:
|
||
|
|
Enables the virus
|
||
|
|
-scan plugin of c-icap-modules using ClamAV
|
||
|
|
:Scan for filetypes:
|
||
|
|
The type of files which should be analyzed.
|
||
|
|
You should scan as many file types as possible but keep in mind that
|
||
|
|
scanning requires resources which have to be available.
|
||
|
|
:Send percentage data:
|
||
|
|
Amount of Data of the original file which should be included in the preview.
|
||
|
|
More Data will have better scanning results and is better for security while
|
||
|
|
a lower value improves performance.
|
||
|
|
:Allow 204 response:
|
||
|
|
A 204 response has the advantage, that the data don't have
|
||
|
|
to be sent over the wire again. In case of a preview, no more data
|
||
|
|
will be sent to the ICAP server and the data will be forwarded to
|
||
|
|
the client. In case of all data has been received by the ICAP server,
|
||
|
|
the data does not need to be sent back. Please note, that the ICAP client
|
||
|
|
has to support 204 responses.
|
||
|
|
:Pass on error:
|
||
|
|
In case the scan fails, the file can be passed through.
|
||
|
|
This is less secure but keeps the business running in case of failure.
|
||
|
|
Keep in mind that this may put your network at risk.
