True but, Mark is extremely busy and not particularly interested in

with first consulting Mark and adhering to his authoritative response

Re: [AMaViS-user] amavis-stats-0.1.17 Released

2005-10-28 Thread Helmut Schneider

Hi,


Rewrote web interface, added templates for easier customization.

Added additional statistic scanning for bad headers.

SEE:
http://www.daleenterprise.com/amavis-stats



Is there any how-to? I succesfully installed it but I can't see the 
buttons on the top. Maybe there are missing some php components:


Are the buttons present but no text appears???

A link to the installed software would be helpful.


The problem was PHP5. I installed PHP4 and now it works exept that the per 
domain statistics are empty.

 OK, I'm free, have time.

 Please outline requirements and goals.

 Do you wish this to be a true snmp agent solution or a web/email/
 console solution that mimics the snmp protocol?

 Expected features (minimum acceptable as well)?

 Now my two cents worth, making the agent adhere to the snmp protocol
 makes it difficult to do in perl without a lot of hacking, a C
 solution might be a better choice and would make communication via
 the snmp C API a simple one to achieve but would limit the use
 without writing a stand-alone client to go with it, of course the
 client could be perl based but only speculation.

 Of course, you could go the PHP/snmp route and use apache to handle
 the communication aspect which would effectively act as agent/client
 via a browser without too much difficulty.

 Anyway, as number 5 says, need input..

[AMaViS-user] [OT] Commercial solution pricing

2005-10-28 Thread Paolo Cravero as2594

Hi,
I thought you might like to know how much a commercial solution _very_ 
similar to amavisd-new+ClamAV+SA+MySQL+mailzu costs.


Something with AV+AS and webQuarantine to be installed on your own 
hardware, and a nice web interface for management (configuration).


For 10k mailboxes it is about 12 USD/mailbox/year. But for 200 mailboxes 
the cost increases to 50 USD/mbx/year. There are of course reductions if 
the license coves 2 or 3 years.


How much money is your setup worth? :-)
Paolo

Re: [AMaViS-user] amavisd-agent

2005-10-28 Thread Mark Martinec
 Please, can you outline requirement and goals to me too? Can you
 address me to find some specification to develop an SNMP agent?

Here it is, sorry this took me so long.



Two tasks need to be addressed:
- devising and specifying a content-filtering MIB
- providing access to the MIB (a SNMP agent)


Devising and specifying a content-filtering MIB
---

While designing a MIB, the following should be taken as a reference:

- collect ideas from Mail Monitoring MIB (RFC 2789, aka MTA-MIB)

As amavisd-new behaves in many respects as a true MTA, a
subquestion is whether a SNMP agent should provide two subtrees:
one a pure RFC 2789, the other a specialized amavisd-new MIB,
or would a non-standard specialized amavisd-new MIB suffice?
Would clients benefit from a MTA-MIB view of amavisd?

- see what variables are currently collected by amavisd-new

* by running amavisd-agent, or
* by directly browsing a database by: db_dump -p /var/amavis/db/snmp.db
* by checking the source for variables which only rarely show;

- a MIB description must be compliant to the SMIv2 (which can be
  automatically converted to SMIv1 if needed).

- consider potential future needs and broader use when designing a
  content-filtering MIB, so that it might be useful to other content
  filtering applications;

The currently provided variables collected and provided by amavisd
are mostly of types Counter32 and octet string. It is quite likely that
the following types will be used in the future: integer, Gauge32, TimeTicks,
and IpAddress. It it unlikely that Counter64 would be needed. The type
of each variable is already provided in a database.

Most variables are simple non-aggregate objects. Besides these there
is a set of counters to be represented as a table, i.e. a table of
encountered virus names and associated counts.

Furthermore there is a set of counters of a form OpsDecType-xxx, where xxx
could be one or more 'short content types', e.g. OpsDecType-audio.mpa.mp3.
It is not obvious what would be a best representation of these.
Some aggregate representation would probaby be desired.

There are currently no variables of type Gauge32, although it is
not hard to imagine that such could be useful in the near future.
An example may be a current size of a quarantine or tempdir area,
It is also easy to imagine that variables of a TimeInterval type
would be useful (e.g. LastOutboundActivity, LastConnectToSQL).

It is unlikely that traps would be added in a near future, and even
less likely that write or create access would be needed for a variable.

It is unclear whether a concept of 'groups' from MTA-MIB would be useful
in the context of amavisd-new. Perhaps considering groups like (spam, virus,
etc.) or groups according to a policy bank path selected? Would that be
too far from the spirit of MTA-MIB groups?

The view of amavisd-new variables should represent a running instance
of amavisd-new as a single entity, aggregating information from all
child processes into one set of variables. This aggregation is already
provided by using a Berkeley db, so this has already been taken care of.
This need for aggregation is also one of the reasons why a SNMP agent
or a subagent can not be implemented in each child process.

When amavisd is restarted, all counters in a database are reset, and the
sysUpTime timeticks variable is also reset. This may be shown to SNMP
clients unchanged, or a SNMP agent may decide to implement cumulative
counters which survive across daemon restarts (proper unsigned wraparounds
would need to be done correctly). If the agent also provides other MIBs
of the system and supplies a 'system' MIB reflecting the machine uptime,
it may be more logical to hide amavisd restarts to clients unless when
this specific information is being sought.


A SNMP agent - providing SNMP access to the MIB
---

Writing a SNMP agent from scratch would be a nightmare. SNMP is a can of
worms when one looks behind simple variable associations and descends
into details. As far as I'm aware there isn't any Perl implementation
or significant support for writing a SNMP agent (although there are several
modules to support client-side). It also appears that the only noteworthy
community efforts are concentrated around the Net-SNMP project, which has
good and active tradition and offers a support for a range of Unix platforms.

Net-SNMP
  http://www.net-snmp.org/
  http://www.net-snmp.org/docs/FAQ.html

It supports the SNMPv1, SNMPv2c and SNMPv3, which is what we need. It
provides a library, a set of tools, a client and an extensible agent.

Extending an existing agent (compared to writing one from scratch) hides
us from the intricacies of the protocol and differences in its versions,
access controls, MIB views, BER encodings, ...

When deciding what mechanism should be used to extent the Net-SNMP agent
a need to decouple Berkeley db 

[AMaViS-user] Amavis-new 2.3.1 | warnings

2005-10-28 Thread Pablo L. Arturi
Hello guys.

I have setup amavis-new + postfix + courier-imap with MySQL support for
everything, including storing quarantine messages; and it seems working
excellent by now.

The only think I see is that amavis doesn't care what I set in
warnvirusrecip - warnbannedrecip and warnbadhrecip in the policy table, it
won't send notifications never.

Does anyone know how can I enable this? I think it's useful so each
recipient can know if someone tried to send him a virus and so on.

Well.. thanks in advance,

Regards,
Pablo

 Hi,
 Our security team wants to use the following logic for Virus

 Amavisd.  The logic is:

 *) Alert the virus admin any messages sent to security@ (It may be 
 acceptable to send notification to the destination instead/also).

 I think $warnvirusrecip is about as close as you are going to get without
 modifying code.

Correction, user@ is a valid lookup target.

@virus_admin_maps = ({

'.' = undef,

Perhaps these recipients do not match your @local_domains_maps ?

Sorry, you are using 'sh'.

Do you get a response if you simply run 'su amavis dspam' ?
and
su amavis /usr/local/bin/dspam ?

If you first installed it somewhere else, then deleted it, then
installed it in /usr/local/bin/dspam, try:
