[SOLVED] Restrict by using hosts.deny

masatheesh · 11-20-2009, 02:56 AM

Hi,

Is it possible to use hosts.allow and hosts.deny files to restrict all access? For example,consider the following content of hosts.deny file of 192.168.0.1

ALL: ALL

Will it restrict the access of 8080 port of192.168.0.1 from 192.168.0.2?

Hi, as far as I know, the hosts.x files work together.

hosts.deny ALL:ALL, denies all that are not listed in hosts.allow

But that's all I know about it.

There are other tools I use to manage what ports are open to what ip addresses.

Like iptables and squid (proxy server)

I suggest you look into these programs.

Regards Glenn

tcpwrappers work only for applications that have the libwrap module compiled in.
to find out, run ldd /path/to/executable | grep libwrap

the example you have above would restrict access to any apps with libwrap compiled in from 192.168.0.1

Like glennspref says - you are better off using iptables.
