CSCF / Jason Testart have set up a small lab
for people to use for this course (and only for this course).
Thanks very much to Jason and to CSCF for setting this up.

It can be used for development and testing for your assignment
but is also intended to allow people to do testing and debugging
and possible kernel modifications for course projects.

The lab is in DC 2569 and there is a keypad lock on the door
(come and see me to find out the password).
Also contact me to find out what user ids and passwords are.

There are four computers that all have a standard install of Ubuntu
Linux 5.10 (with all patches).  In case you are not familiar with
Ubuntu, it's a Debian-based distribution with a more frequent release
cycle than Debian.  

There are two Ubuntu CDs in the room in case a reinstall is required
(shouldn't until later in the term if/when people start modifying kernels).

The computers are labeled "cs856pc01" through "cs856pc04".  cs856pc01
has two 10/1000/1000 NICs (with only one configured), the others have
one 10/100/1000 NIC each.  

cs856pc01 could be configured as a server while using 
cs856pc02, cs856pc03, and cs856pc04 as clients.

All computers are connected to an unmanaged 10/100/1000 switch in the
room, and from there is a single connection to our switch.  The network
for the lab is isolated using our Netscreen firewall.  The subnet for
the lab is 10.15.10.0/24 (sorry, no DHCP available).  This network is
visible from most other CS networks but only ping/traceroute is allowed
inbound (and now ssh).  

Access to outside of the CS firewalled nets is accomplished
via NAT.  Outbound traffic to other CS networks and the world is
restricted to HTTP, HTTPS, NTP, SSH, and passive FTP.

----------------------------------------------------------------------
You can ssh to these machines from the following networks:

  129.97.152.0/24 (core.cs and student.cs unix environments)
  129.97.84.0/24 (cs "client-only" subnet)
  129.97.7.0/24 (cs research firewalled subnet)

Being private, we don't have DNS set-up.  Here's the name/IP mapping:

cs856pc01   10.15.10.11 (eth0) and 10.15.10.111 (eth1-disabled)
cs856pc02   10.15.10.12
cs856pc03   10.15.10.13
cs856pc04   10.15.10.14
