Changelog

• Persistence in ports and services. Therefore, they will no longer be reset after a reboot of the game server.
  
  
• Computers in LAN networks can have active services even if they are not configured in the router.
  This means that from now on there will be many less npcs computers with all the ports closed when you make an nmap on LAN computers. At the moment only ssh and ftp.
  
  
• Avoided the repetition of external ports in a router during world generation.
  
  
• Now the services like Students, Employees etc are all SQL type and use the same port by default, although the number may vary since repeated ports are not allowed. At the moment there are still no hacking techniques to be used in SQL-type services.
  
  
• Nmap correctly indicates the name and version of a service even if it is not running in its default port.
  
  
• Improvement and correction of bugs in the procedural generation.
