Re: max flowbits fatal errors

Thank you Russ, I very much appreciate the response.

Yes, I am building from source.

I will disable several of the lower-priority rules until this can get
patched.  This will be somewhat painful as our dataflows are pretty unique
and, obviously, we use flowbits heavily.

Will there be a specific bug id# that I can watch-out for?

Looks like that option is broken.  I'll create a bug for it.

Are building from source?

You are so close to the limit, are there any rules you can disable?

I am running into the following fatal error when starting snort:

  "ERROR: FLOWBITS: The number of flowbit IDs in the current ruleset (513)
exceed the maximum number of IDs that are allowed (512)."
  "Fatal Error, Quitting."

I tried setting the global configuration option in snort.conf:  "config
flowbits_size: 768"  which really resulted in the really confusing error:
  "ERROR: /etc/snort/snort.conf  Invalid argument to 'flowbits_size':
768.  Must be a positive integer and less than 256."

Running on snort v2.8.6.1.
Tried finding help in the snort manual and README.flowbits with no
success.
Also did not find any command-line options that would help.

Can someone point me in the right direction regarding bumping-up the
maximum number of flowbits IDs ?
And what exactly does the "config flowbits_size: nnn"  configuration
option do ?

Thank you,
K.Panda
