           Summary: Cisco ASA format is not understood
           Product: syslog-ng
           Version: 3.0.x
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: unspecified
         Component: syslog-ng
        AssignedTo: bazsi at balabit.hu
        ReportedBy: vincent.panel at telindus.be

Syslog-ng receives messages like this from Cisco ASA devices :

<PRI>MM DD YYYY HH:mm:ss HOSTNAME %MSGID: CONTENT

"YYYY" part is not conform to BSD-style syslog timestamp : it shouldn't exist. Unfortunately, it can't be changed on the ASA side.
Syslog-ng does not see any header in this message and think "MM" is the process sending the message, hence adds ":" behind it. Additionnaly, syslog-ng
prepends its own header which leads to a total mess in the destination syslog...

On the other hand, syslog-ng also receives messages from another Cisco device (FWSM) like this :

<PRI>MM DD YYYY HH:mm:ss %MSGID: CONTENT

Note the hostname is not specified. And this format is well understood by syslog-ng (no prepended header, no ":" after the month) !

I've also read here : http://www.balabit.com/dl/html/syslog-ng-v3.0-guide-admin-en.html/ch02s17.html#bsdsyslog_header syslog-ng
should be able to understand "PIX extended format" but I can't find anywhere in the documentation nor on the internet what it refers to...

So would it be possible to make sure the first format is well understood by syslog-ng ?

Regards,

Vincent Panel
