Run MineMeld over HTTP

Run MineMeld over HTTP

I'm in the process of running multiple MineMeld behind a server load balancer. I want the backend MineMeld servers to run the application over HTTP. The reason for this is I want to offload SSL from the servers. Currently, nginx redirects HTTP to HTTPS.

 

What would I need to do within the nginx configuration file to stop the https daemon and have the server only serve requests over HTTP?

Re: Run MineMeld over HTTP

Hi @nopsled,

you should change the config /etc/nginx/sites-available/minemeld-web.conf to listen on port 80 instead of port 443:

 

# the original redirect should be commented out
# server { # listen 80; # server_name ~(.+)$; # return 301 https://$1$request_uri; # } server {
# listen on port 80 with no SSL listen 80; [...]

Re: Run MineMeld over HTTP

I do not have situation that nopsled has, but there is valid use case for use Minemeld over HTTP. From security perspective HTTP is definately not an option, but when you want to ensure the availability of Minemeld list in your firewall in EDL then Minemeld has to be up and running all the time. If Minemeld machine and thus Minemeld list for EDL is not available over HTTPS then EDL list seems to get emptyed. To avoid this situation and to make sure that firewall uses last successfully retrieved list HTTP has to be used. Here is exact information on this: "If the web server is unreachable, the firewall will use the last successfully retrieved list for enforcing policy until the connection is restored with the web server, but only if the list is not secured with SSL."

Link for the resource is here: https://www.paloaltonetworks.com/documentation/80/pan-os/pan-os/policy/use-an-external-dynamic-list-...
