Hi,
ipcop intrusion detection system returns this advice

Sid:528
Under normal circumstances traffic to the localhost (127.0.0.0/8) should
only be seen on the loopback interface (lo0).

an indicator of unauthorized network use, reconnaisance activity or
system compromise. These rules may also generate an event due to
improperly configured network devices

How to set up an iptable rule to fix it?
Thanks

You plan to use an iptable rule to fix your network misconfiguration? Read
the message. It says your network is misconfigured. 127.0.0.1 is local. Get
it? Iptable rules is the wrong approach. Fixing that bad entry you put in
/etc/hosts would be a better approach.

I agree with you, the problem is that I am a newbie in Linux and I am not
able to fix that. I tried to remove that entry but nothing changed? Can you
indicate the way?
Thanks

You can see the contents of your /etc/hosts file, but you have no idea what
to do. We have an idea what to do, but we cannot see the contents of your
/etc/hosts file.

Shall I set off marine emergency flares for you? Beat drums at midnight?
What does it take to get people to post something besides idle banter?

the etc/hosts content is simply
127.0.0.1 localhost
192.168.10.15 ipcop

The intrusion detection system indicates a possible device misconfiguration,
I am expected to deal with a driver not hosts file. ?????

I just checked and you don't say which distribution you have. Therefore, on
general principles, not because I know this is required, change the first
line to:

127.0.0.1 localhost.localdomain localhost

It may not matter, depending on your distribution.

They are interrelated. The configuration files in Linux pretty much make or
break your network capabilities and degree of protection against intrusion.

Also, the entire idea of computers is software (written, evanescent things)
controlling hardware (solid, corporeal things).

I AM being patient. When I stop being patient, you'll know.
