[NFBCS] Accessibility of PacketTracer

[rjaquiss at earthlink.net]

Hello Brian:

     Thank you for your note. My question about accessing equipment is
academic at this point. At age 73, I am not about to try for a CCNA.
Packet Tracer is a program used to simulate networks. Students can create a
simulated network of PCs, routers, switches etc. and then test their
network. This is done so schools don't have to equip labs with racks of
hardware.
I nearly failed a test because I was handed a cable and asked to identify
which connector was attached to it. The connector shell had markings which
were in print. I ended unscrewing the connection in order to find out if I
had a DTE or DCE cable. It was a good thing that I had good mechanical
skills. Those were long pins.
More later.

Regards,
Robert

	hello Robert.  Yes, in general, routers and switches can be
controlled via a terminal interface, either via a serial port or via an ssh
terminal connection.  Some of the lower end equipment, i.e. Net Gear, D-link
etc. must be configured through a browser, but all of the enterprise
equipment I'm aware of can be fully controlled through a terminal.

I'm not familiar with packet tracer, but I wonder if tcpdump, a command line
packet capture tool, can be used instead of packet tracer to complete the
course work?  Tcpdump is fully accessible via command line.

-thanks
