[Snort-users] slahes in SQL statement a problem?

You can try escaping the slash (ie just add another one) ... D-TRITON:\\ which would mean to take the slash literally ... 

Normally in PHP apps its common to use a method to add slashes so the DB does not choke:

$sql = addslashes($sql);
http://us4.php.net/addslashes

It could also be if you have a ' character around sensor name ...

  Hi,

  Can't get snort to output into MySQL running on Windows 2K Box - permissions are fine....I think it has something to do with the slashes in the 'sensor name' when trying to execute the first SQL query...

  when I take the SQL from the error message and try to run it in MySQL (logged in with the same user) the SQL statement is not valid because of the '\' in the VALUES section of the statement....

  my output database line is set to mysql and seems not to be the problem....

  do I need to wait for the a snort.exe to account for slashes in sensor names or is there something I'm missing?? error message below - any help is appreciated...

  database: Problem obtaining SENSOR ID (sid) from snort->sensor
  ERROR:
   When this plugin starts, a SELECT query is run to find the sensor id for the
   currently running sensor. If the sensor id is not found, the plugin will run
   an INSERT query to insert the proper data and generate a new sensor id. Then a
   SELECT query is run to get the newly allocated sensor id. If that fails then
   this error message is generated.

   Some possible causes for this error are:
    * the user does not have proper INSERT or SELECT privileges
    * the sensor table does not exist

   If you are _absolutely_ certain that you have the proper privileges set and
   that your database structure is built properly please let me know if you
   continue to get this error. You can contact me at (roman at ...438...).

  Fatal Error, Quitting..
