disclaimer: new to Linux and snort.
i just installed newer version of Snort on Kali linux running in VMWare Pro. However, the older version seems to be still installed.
As per below. How do i remove ver 2.9.2.2 ?

In addition after upgrade, when I ran either of the versions, I get

" WARNING: No preprocessors configured for policy" message
How do I remove the old preprocessors in defined
preprocessor directory?
Exact instructions would be appreciated. Thank you!

Kali based on Debian testing should be able to apt remove purge commands.

Just make sure you type out the whole version number maybe. I don't know as I don't run Kali.

dpkg -l should have something to say also.

Ubuntu community usually comes back with the most hits when searching

Lastly. I am surprised that Kali does not come synaptic package manager and the OP seems clueless about that feature also, running a penetration testing distro fulltime.

The removal method depends on the installation method. How did you install both versions?

Well, running Kali Linux was not my choice, but a requirement for the cyber security class :-). The project that I chose was snort

Hi, Bernard.

I installed the latest version from source. Followed install instructions at https://upcloud.com/community/tutori...ort-on-debian/

The older version, I installed about 2 months ago and didn't touch it since. I don't remember much from that install. I believe I had to add old repos to conf the file (I removed them since then) in order to install snort.

Please ignore my additional question about preprocessors warning. I figured it out.

If you don't know how you installed the old version, I can't help you deinstalling it. Although it looks like you used APT, so apt purge snort should do the trick.

EDIT: Why is it a problem to have two versions? Just keep both.

Thank you! Synaptic was a breeze.

wasn't sure if the following versions (same as latest versions)
libdaq vers 0.6.2-2
libprelude ver 1.0.0-9
oinkmaster ver 2.0-4
needed to be uninstalled as well.. so i left them there.
