An interesting account of the controversy surrounding Linux security.
Where does PLUG weigh in on security vs speed and ease of use? Is our
friend and neighbor Linus right or should we go with less famous "security
experts"?

on a switched network, this only works if the system whose arp table you're
examining has successfully communicated with the printer at some point.
this method is often combined with an IP range port scan to try to populate
the arp table for later viewing. but that is more complicated than we woul
As a network engineer, here's how I'd approach this problem. Maybe it's
helpful to you.
1. Run the command "arp -a" from the pc. This will give me a list of mac
addrs to ip addrs mappings for all the network interfaces that are on
the subnet from which I'm running the command.
e.g.
mannix@mc-
I have a different HP printer model and a mixed wired and wifi LAN. A few
things to check -
1. Look at the printer manual (get one from HP online if you have to) and
be sure to set up a static IP address for the printer from the control
panel on the printer.
2. Be sure to install the latest HP pr

Wikipedia says the 4100 was sold between March 2001 and February 2003.
Zeroconf was certainly under development by then.

Wes;
Thanks much for the valuable insight.
As you suggested, i ran the "ifconfig" command.
These are the results i received:
~~~
ifconfig
eth0 Link encap:Ethernet HWaddr 00:27:13:b1:ff:c5
UP BROADCAST MULTICAST MTU:1500 Metric:1

Charles,
Are you using DHCP or static IP addresses?
What is in /etc/hosts?

I agree that this is an issue with the printer's IP address. I have a few
of these. I'm too lazy to write down all the steps to deal with this, but I
made a video of how to view and set the IP.
