tlug: ipchains logs and nmap audit

[Subba Rao <subb3@example.com>]

I have several ipchain rules. One of them is:

ipchains -A input -i ppp0 -p TCP --destination-port 21 -l -j DENY

Why are these ipchains not doing any logging?  I do have the -l option
invoked for logging. The packet is supposed to be denied at the IP level
and then logged into syslog. When I try to connect from another address to
the IP address of the ppp0 interface, nothing gets logged. Instead, the tcplogd daemon
captures it into the log. tcplogd is an application level filter and not at IP level.
Why is this ipchains rule (and others) not getting logged?

The kernel is 2.2.14.

None of the connections to the services are getting logged by ipchains filters.

I have used nmap on the ppp0 interface and yet it is not getting logged.

How are you auditing your services on the ppp0 interface? What options in ipchains
are you using to do the logging?
 
Thank you in advance.
