Changeset 9300 in orxonox.OLD for branches/proxy

Timestamp:

Jul 17, 2006, 10:15:33 AM (18 years ago)

Author:

Message:

work from this weekend in the train

• the ip should now synchronize over network in the handshake (always the favorite 2 proxy server ips)
• the network monitor now keeps track of all network nodes answers with proxy server lists if asked/needed
• it is untested

Location:
