    tcpwrappers

    Hi im using xinetd to host my services, and i was wondering are hosts.allow hosts.deny files only used by inetd ?, i know that xinetd has it's own built in tcpwrappers using syntax like only_from = 0.0.0.0 and no_access = 0.0.0.0 , i was just wondering if i would still have to implament this into hosts.allow and hosts.deny

    Typically only services in inetd services are wrapped (and you usually have to configure inetd to wrap those services); however, you can often times compile in the ability to use tcpwrappers in other packages (for example openssh). You will have to check the documentation of whatever service you are trying to run and whether or not tcpwrappers are a configuration issue.

    You may be interested in Psionic's PortSentry. This may help.

    If you are running linux, you may be better off running iptables.

    There is only one constant, one universal, it is the only real truth: causality. Action. Reaction. Cause and effect...There is no escape from it, we are forever slaves to it. Our only hope, our only peace is to understand it, to understand the 'why'. 'Why' is what separates us from them, you from me. 'Why' is the only real social power, without it you are powerless.

    FYI- PortSentry is now owned by Cisco and I don't believe they offer it for download.

    You can still get it if you know where to look....

    search google for "index portsentry"
