deny.hosts does not work in blocking anything
Hi All,
I'm running fedora redhat and I'm trying to test my hosts.deny file. I've opened up a connection on : port 143 with this command for netcat nc -p 143 -l This creates a pseudo server that I then try to connect to from a remote host. Now I have set hosts.deny to --> ALL : ALL and hosts.allow to --> ALL: LOCAL However everytime I try to connect to port 143 it lets me login when it should be denying me access? I thought Fedora would have support for hosts.deny even on a basic install? What is wrong here? |
The hosts.allow hosts.deny files are part of the tcpwrappers system.
To be able to use this kind of control the server need to be compiled with tcpwrapper support. Some server functions are ready to run with tcpwrappers while others need to be recompiled or just replace the command line that runs the server. Usually in the /etc/xinetd.conf or /etc/xinetd.d/ |
what about sendmail?
