Thanks for the responses.

Yes, these and all the other preprocessors are in this dir
and linked.  Here is the output from this dir:

Hi,
do you have libsf_ftptelnet_preproc.so on this dir ?
  /usr/local/lib/snort_dynamicpreprocessor/
and please send "ls -la /usr/local/lib/snort_dynamicpreprocessor/"
Regards
Rmkml

Hello.

I'm trying to build 2.7.0.beta1 on Ubuntu 6.06.  So far
things are
working well, except when I attempt to turn on the dynamic
preprocessors.

I encountered an ID error when I simply uncommented them
so I added
some text to make them look like the command line
counterparts.  I'm
not certain whether they work from the command line, as I'm not
interested in starting them this way.

Starting snort with 'sudo' using the one and only parameter:  '-c
/etc/snort/snort.conf' I get the following output:

 ERROR: /etc/snort/snort.conf(539): Bad rule in rules file

This line contains:

 dynamic-preprocessor-lib

/usr/local/lib/snort_dynamicpreprocessor/libsf_ftptelnet_preproc.so

I get this error with any dynamic preprocessor enabled in
snort.conf.

I've reviewed  the documentation and could find nothing
indicating the
correct format for the 'dynamic-*' options for snort.conf
(the command
line is well documented...) and I reviewed the list and
forums with no
luck on a solution.

Cheers,
