Using F-Secure Linux Security with fedora & amavis

Hi,

I'm trying to implement F-Secure Linux Security version 11.x with amavisd-new on fedora. I've read that it doesn't work very well with amavisd-new, but that's what we've implemented on the servers in our organization, so I'd like to try.

 

I've tried using the following:

 

['F-Secure Antivirus for Linux servers',
['/opt/f-secure/fssp/bin/fsav', 'fsav'],
'--virus-action1=report --archive=yes --auto=yes '.
'--usedaemon --socketname=/tmp/.fsav-0-fsav --dumb=yes --list=no --mime=yes {}', [0], [3,4,6,8],
qr/(?:infection|Infected|Suspected|Riskware): (.+)/m ],

 

Running that same command-line manually results in:

 

# /opt/f-secure/fssp/bin/fsav --virus-action1=report --archive=yes --auto=yes --usedaemon --dumb=yes --list=no --mime=yes --socketname=/tmp/.fsav-0-fsav /root/macro-virus

F-Secure Anti-Virus CLI version 1.0 build 0060

Connect to fsavd failed: Connection to fsavd failed.

I've also tried without the socketname and usedaemon options and it produces the following error:

 

Aug 30 03:29:50 alex amavis[733]: (00733-01) (!)run_av (F-Secure Antivirus) FAILED - unexpected exit 1, output="Something wrong in initializing backend. Code:256\nFATAL: Failed to get configuration"

There are also the following errors in /var/opt/f-secure/fsav/fsoasd.log:

 

1472664157 | ERROR | 0xf7241b40 | fsoasd/AvJudge.c:0334 | Allowing access on error: '/var/spool/postfix/incoming/7FB5522120'

Any ideas greatly appreciated. I don't fully understand how it should be implemented.

Thanks,

Alex

Re: Using F-Secure Linux Security with fedora & amavis

Hi, I posted this question a few days ago and no one has responded. Is there no one that can help?

 

Is there a more appropriate forum I should post my question?

Re: Using F-Secure Linux Security with fedora & amavis

From the given information, it seems that the connection to the scanner daemon (fsavd) cannot be done properly in your environment.
There is a possibility that it is caused by the missing libraries or system related issues such as server high load and etc.

Information about the necessary libraries can be checked from the following pre-installation checklist page.
There is no information for 'Fedora' because that distribution is not supported by Linux Security version 11.00.

URL of pre-installation checklist:
https://community.f-secure.com/t5/Business/Pre-installation-checklist-for-F/ta-p/76128

Hence, we would recommend you to install and use Linux Security version 11.00 only in the supported Linux environments which are listed in the release notes below.

Supported Linux distributions

The following 32-bit Linux distributions are supported:

    CentOS 6.0-6.7
    Debian 7.0-7.9
    Debian 8.0, 8.1 **
    Oracle Linux 6.6, 6.7 RHCK*
    Red Hat Enterprise Linux 6.0-6.7
    SUSE Linux Enterprise Server 11 SP1, SP3, SP4
    Ubuntu 12.04.(1-5) 14.04.(1-3)

The following 64-bit (AMD64/EM64T) distributions are supported:

    CentOS 6.0-6.7, 7.0-7.1
    Debian 7.0-7.9
    Debian 8.0, 8.1 **
    Oracle Linux 6.6, 6.7 RHCK *

    SUSE Linux Enterprise Server 11 SP1, SP3, SP4
    SUSE Linux Enterprise Server 12
    Ubuntu 12.04.(1-5), 14.04.(1-3)

*) Red Hat compatible kernel (kernel-2.6.32-573.el6)

**) The on-access scanning is not supported on Debian 8 because the kernel configuration has fanotify disabled by default.
--------------------------------------------------------------------------------------------------------------------------

Apart from that, we do not provide any explicit support for the third party applications such as Amavis.
Due to this, 'fsav' command-line of Linux Security version 11.00 might work or might not work for such implementation.

Re: Using F-Secure Linux Security with fedora & amavis

Is the damon really listening? Are rights set up correctly? SElinux?

 

I'm testing out a Zimbra mailserver setup now that uses amavis-new, but not the daemon, it calls fsav for each mail.

 

It has been running F-Secure 9.20 and I'm checking how to install 11.0 and if there are any changes needed.

 

The entry for F-Secure in the amavisd.conf here looks like this:

 

  ### http://www.f-secure.com/ version 9.14
   ['F-Secure Linux Security',
    ['/opt/f-secure/fsav/bin/fsav', 'fsav'],
    '--virus-action1=report --archive=yes --auto=yes '.
    '--list=no --nomimeerr {}', [0], [3,4,6,8],
    qr/(?:infection|Infected|Suspected|Riskware): (.+)/m ],
    # NOTE: internal archive handling may be switched off by '--archive=no'
    #   to prevent fsav from exiting with status 9 on broken archives

Making a test file with an eicar virus signature and running the command from the conf file from the command line instead:

 

fsav --virus-action1=report --archive=yes --auto=yes --nomimeerr /tmp/eicar

works:

# fsav --virus-action1=report --archive=yes --auto=yes --nomimeerr /tmp/eicar
F-Secure Anti-Virus CLI version 1.0  build 0060

Scan started at Mon Sep 26 11:22:49 2016
Database version: 2016-09-26_05

/tmp/eicar: Infected: EICAR_Test_File [FSE]
/tmp/eicar: Infected: EICAR-Test-File (not a virus) [Aquarius]

Scan ended at Mon Sep 26 11:22:50 2016
1 file scanned
1 file infected

And sending it to Zimbra -> amavisd
