[cobalt-users] Update on previous post: RAQ3 email: random attachemnts get basterdized (esp .zip and .jpg)

["Lab Mail" <mbeaudry@xxxxxxxxxxxxxxx>]

This email regards my earlier email (which can be found:
http://list.cobalt.com/pipermail/cobalt-users/2002-December/083184.html and
is similar to:
http://list.cobalt.com/pipermail/cobalt-users/2002-April/067800.html).

Summary:

Almost at random, ATTACHMENTS sent TO users on the RAQ  MAY OR MAY NOT get
damaged in some manner. A sample of this damage can be found:
http://www.insanitylab.com/troubleshoot/corrupt_jpg.html . The sample is of
a jpg which is to be sent as an attachment. The first pic on the page is how
the attachment SHOULD arrive. The second (scroll down) is how the attachment
IS arriving. Note the great big bejezus color bars....

When this first occurred, the hardware configuration inbound was:

ISP Cable-Modem
Linksys BEFSR41 Router (NAT)
RAQ 3

The original software configuration was:

RAQ3 (all updates)
Bassi-Mailscanner
PHP 4.0.6
Bassi-MySQL
Webalizer Release 2
Bassi-PHP-My ADMIN

The system had run for months without error, then this 'corruption' started
occurring. Frustrated to no end trying to resolve the issue, I slipped into
"testing mode" where I rebuilt the RAQ3 twice. Once with the original RAQ3
software ONLY (no other applications running) and the result was the same
almost immediately. Second time I used the RAQ4 OS on the system (yes, I
know, me bad...but this is only for a test, it will go back to "stock"
shortly) with the following software installed:

Relational Database Server and Client tools by InterBase. Release V6.0
MySQL Release 3.23.54-1
Cobalt OS Release 6.0
PHP Release 4.1.2-3
RaQ4-All-Kernel Release 2.0.1-2.2.16C33III
RaQ4-All-Security Release 0.0.1-8061
RaQ4-All-Security Release 2.0.1-1-15673
RaQ4-All-Security Release 2.0.1-13323
RaQ4-All-Security Release 2.0.1-13453
RaQ4-All-Security Release 2.0.1-14039
RaQ4-All-Security Release 2.0.1-14559
RaQ4-All-Security Release 2.0.1-14997
RaQ4-All-Security Release 2.0.1-15417
RaQ4-All-Security Release 2.0.1-2-15787
RaQ4-All-Security Release 2.0.2-14936
RaQ4-All-System Release 2.0.1-12854
RaQ4-All-System Release 2.0.1-13993
RaQ4-All-System Release 2.0.1-14185
RaQ4-en-OSUpdateRelease 2.0
Webalizer Release 2.01.10-1

The system ran flawlessly for roughly 40 days, then *poof* the corruption
began recurring. Now bear in mind that there is NO AOL permitted nor in use
on any system that is involved in transmitting/receiving the emails that are
being corrupted, so there is no chance "aol's cache server is converting
them into .art files" can be affecting these files.

So, I can only conclude that one of the following is occurring:

1) The LINKSYS Router is the problem, possibly stripping bits off the
attachment?
2) There's a button in the RAQ's management console that says "clear
bizzarre cache problems from memory and quit eating attachments" that I
haven't found yet...

Now, before I proceed and dangle my RAQ out in the great wild Internet (I
hope to install some protection before I do) to investigate the "Linksys NAT
Router" angle, has anyone else accumulated any extra bit of information
since my last posting that may help? The archives don't reveal such, but I
thought I'd try....maybe I'm using the wrong words....

thanks...
