Research direction

Start by reading etc_ccpmblocker.lua and reproduce the reported behavior by connecting through active and passive users. Investigate why CCPM connections succeed for some users despite the script, then verify that users in both connection modes are blocked consistently.

Written by the indexing model from the issue text.

Description

It seems that not all users get blocked with this script. It is not working to 100 percent. I have tried to find the reason, but so far i haven't found out when and why.

When i test to connect to both active and passive users it seems that there is a higher success rate to connect with CCPM if the user is connected as a passive user.

In a hub with 300-400 users i was able to established CCPM to 12 to 15 users, most of them was connected in passive mode.

I know that only one hub that allows CCPM is enough to established a CCPM connection. We only had one common hub.
