Will hosts.deny work as intended (i.e. blocking access in conjunction with fail2ban) on Debian Squeeze?
I installed the server with ISPCONFIG3 following Falko's perfect server HOW-TO.
Now I read somewhere that services/daemons listen themselves to ports, and don't use inet.d to initiate connections, so hosts.deny would not work.
Is that correct?
Which are the services that are TCP-wrapped (ie. using inet.d) and which are not?
Second, if hosts.deny indeed does not work as intended, and since I run a virtual server I do not have access to iptables: what solutions do I have for blocking unwanted IPs ?
