[Oisf-users] suricata-update modify does not appear to work any more ?

I have now established that some mods are working as expected!   They just don’t trigger a message in the verbose output and that confused me.

So presumably that means that there is something wrong with the pattern matching.  

The obvious thing would be the escaping of the ‘$’.  How should this be handled.  ( sample rule below).

Ah!   you need to escape the backslash as well, of course.

Apologies for the noise!
