I have a server with 35 IPs assigned to eth0. I want to have incoming
connections from a single IP limited to only one IP on the server at a time.
For example if someone connects to any port on 1.2.3.4 he/she should not be
able to connect to any other IP on the server until he/she has any open
connections to 1.2.3.4. Once all the connections to 1.2.3.4 are closed the
client could connect to another IP.
I need this so that if someone scans port 21 on a whole range of IPs it will
not start 35 new connections (instances) of Xinetd and/or Ftpd. Any ideas?
Thanks.
