Title: RE: Security with TCP Wrappers

It appears that whatever  I enter in these files I can still get access via telnet form any maching (even if I add single ip exclusions). Is there any way that something is set elsewhere so that these files are being ignored?

Hi,

For an Subnet, your entry in the hosts.allow should be

        in.telnetd : 192.168.1.0/255.255.255.0

Change the Ip Adress and Subnetmask to your, that should be all

Dear All

I'm new to Linux so please forgive me if this is a dumb question.

I am trying to disable telnet access from certain systems/subnets to a Linux Server. I understand this can be acheievd by adding entries to the hosts.allow and hosts.deny files.

I have added

in.telnetd: x.x.x.

to the allow file (where x.x.x is the subnet that I want to allow telnet access)

and I have added

in.telnetd: ALL

to the deny file

So in theory this should allow access to x.x.x subnet and deny everything else?

Problem is I can still telnet from anywhere

Am I missing something?

Thanks
