##### Setting up the Utah Network Testbed software
##### Tested on FreeBSD 4.3, FreeBSD 4.5, FreeBSD 4.6
##### Tested on FreeBSD 4.3, FreeBSD 4.5, FreeBSD 4.6, and FreeBSD 4.7
##### Step 0 - OS installation and setup
First of all, the machine should be configured correctly for the network it is
on, have the root password set, etc.
Install FreeBSD on the machine you'll be using for your ops node, using the
standard FreeBSD installation process. You don't need to worry about which ports
to install, etc., as the ones required by this software will be installed
automatically. You do, however, need to partition your filesystems so that you
have the proper amount of space for certain directories - see below for
It is best to add the following group before creating the following
directories. Basically, testbed software should be in the tbadmin
group. Run this command as root.
pw groupadd tbadmin -g 101
Make sure that you have the network correctly configured.
The following directories will need to exist on partitions that have enough
space to hold them:
/usr/testbed/ - Needs space for testbed software and logs. A few gig should be
plenty. Make sure that you (and anyone
else who will be installing software)
have permission to write to this
/users/ - Needs space for user home directories. Amount of space required
/usr/testbed/ - Needs space for testbed software and logs. A few gigs should be
/users/ - Needs space for user home directories. Amount of space required
depends on how many users you expect to have.
Generally, though, we suggest that users store large
files related to their projects in the /proj directory.
/proj/ - Needs space for project files. We recommend that this be larger
than /users, to encourage people to store files there, which
aids per-project accountability
/groups/ - Needs enough space for files shared by groups. These are
primarily used by classes, if any.
than /users, to encourage people to store files here,
which aids per-project accountability.
/groups/ - Needs enough space for files shared by the sub-groups of
projects. These are primarily used by classes, if any.
/share/ - Exported read-only to all nodes, we use it for providing the
source for the FreeBSD and Linux versions we run to
You may want to enforce quotas on the user-writable filesystems.
##### Step 1 - Package installation
Install the necessary packages. The following are necessary, and available as
FreeBSD ports:
gmake-3.79.1 GNU version of 'make' utility
You may also want to install sudo to give your administrators root access (see
the boss setup instructions for more details.)
##### Step 2 - Testbed tree configuration/installation
Configure the testbed tree. For example, I have the testbed source in ~/testbed,
and use the ~/tbobj directory to do my builds in.
cd ~/tbobj --with-TBDEFS=/path/to/defs/file
gmake ops-install
The defs file you use should be the same one you created for use on your
boss nodes.
##### Step 3 - Mail setup
We use our ops node to handle mail. You'll want to put:
into /etc/rc.conf/. Add the hostnames you'll be handling mail for to
/etc/mail/local-host-names . Make sure to include your domain (eg.,
and your boss and ops node in this file.
Create the /etc/mail/lists directory, which will be used to store mailing lists
for testbed-users and testbed-activeusers, which can be used to conveniently
send mail to all and all active users, respectively.
If you're running your testbed-ops list off a different mailserver, you
might want to add something to your /etc/mail/aliases file like:
Or, you can make a file containing all the people on the testbed-ops list
(one address per line) in /etc/mail/lists, and add:
testbed-ops: :include:/etc/mail/lists/testbed-ops
##### Step 4 - Root access from boss
By this time, you should have created an ssh identity for root on your boss
node (see the boss setup instructions.) Copy boss:/root/.ssh/ to
ops:/root/.ssh/authorized_keys , and chmod it to 600. Make sure you can
ssh, as root, from boss to ops without a password.
##### Step 5 - Exports setup
First, add the following lines to /etc/rc.conf, and restart the machine or
start nfsd by hand:
nfs_server_flags="-u -t -n 16"
Create /etc/exports.head . This should contain exports of /users/, /proj/,
/groups/, and /var/ to all other control nodes BUT NOT testbed nodes. When this
is done, run $(BUILD_DIR)/tbsetup/exports_setup on the boss node, which will
create an /etc/exports file by concatenating this with dynamically-generated
exports of directories to nodes that need them.
Here's an example exports.head file from one of our ops nodes:
/z -maproot=root -alldirs
/var -maproot=root -alldirs
(Note, on this machine, /users, /proj, and /groups are all on the /z
filesystem. You'll need a line for each filesystem that contains these
three directories.)
##### Step 5B - syslog setup.
You need to add some lines to /etc/syslog.conf.
Put this one after the ftp line:
# For Testbed user activity logging /var/log/logins
Put this one at the end:
*.* /var/log/capture.log
Then create the files:
sudo touch /var/log/logins
sudo chmod 640 /var/log/logins
sudo touch /var/log/capture.log
sudo chmod 640 /var/log/capture.log
Then restart syslog:
Make sure that, no matter how you decide to partition things up, you make
symlinks to the appropriate places. ie., if you make one big filesystem called
/z that has /users, /proj, and /groups in it, make sure you:
ln -s /z/users /users
ln -s /z/proj /proj
... etc.
sudo kill -HUP `cat /var/run/`
It's simplest if you don't create any users yet, and just log in a root for the
time being. Our software will create users later, once you get boss set up.
##### Step 1 - Unpacking and running configure
You also want entries in /etc/newsyslog.conf:
At this point, you'll need to make a 'defs' file - see setup.txt for
instructions for doing so. You'll use the same defs file on boss and ops.
/var/log/logins 640 7 200 * Z
/var/log/capture.log 664 7 * 168
Unpack the testbed source, and run it's configure script. Use the --with-TBDEFS
option to configure to give it the path to your defs file.
This is file is read hourly, so need to restart anything.
For example, I have the testbed source in ~/testbed, my defs file in
/users/ricci/testbed/defs-ricci, and use the ~/tbobj directory to do my builds
cd ~/tbobj
~/testbed/configure --with-TBDEFS=/users/ricci/testbed/defs-ricci
##### Step 6 - Capture setup
##### Step 2 - Running the ops installation script
If you don't have serial lines for all the nodes, you can skip this step.
This part is brand-new, so please report any problems with it.
If you're using the Cyclades serial boards, you'll need a custom kernel. For
Cycom-Y boards, include the following in your kernel config file:
device cy0
device cy1
If you have Cyclom-Z boards, contact Utah, as we have custom drivers for them.
In the object tree you've configured (in my example above, ~/tbobj), there's an
'install' subdirectory, with a script called 'ops-install'. Just run this
script as root. It will take care of installing ports, and doing various other
configuration of FreeBSD required to make it into an ops node. The script is
designed so that you can run it as many times as you want, and it'll just skip
stuff it's already done. If it fails, send the output to Utah so that we can
fix it up. If it succeeds, follow any other instructions it may have, then
reboot the machine.
Install capture by changing into the capture subdirectory of your build tree
and running 'gmake tipserv-install'.
(You may have to set the executable bit on this script, since configure won't -
I'd like to get this solved at some point.)
Set up /etc/remote - Each node should have two lines, like:
The first line is for the normal case, of running capture and using tip to
connecto to a running capture process. The second is for convenience when
capture is not running. Change the speed if your nodes' serial consoles are
not running at 115200. Of course, you'll need to change the cuac device for
each node in the second line, to refelct where it's acutally attached.
You should be aware that, among other things, this script sets up sendmail, and
sets up password-less 'sudo' for anyone in the 'wheel' group. If you don't want
these for security reasons, you can undo them after the installation script is
Make a /usr/testbed/etc/capture.rc script to start up the capture process for
each node at boot time. Each node should have a line like:
/usr/testbed/bin/capture -r -s 115200 pc1 ttyC00 >/dev/null 2>&1 &
As above, make sure to the the correct speed and tty device.
##### Step 3 - Installing from source
To install the actual testbed software, simply do a 'gmake ops-install' in your
object directory.
##### Step 7 - Other
##### Step 4 - Setting up mailing lists
It's useful to have the clocks on boss and ops relatively synchronized. During
the setup of your boss node, you set up ntpd. You can use this on ops too, to
synchronize their clocks.
Optional. The ops-install script set up some mailing lists for the email
addresses you set up in the defs file, in /etc/mail/lists . If you want to run
these mailing lists off your ops node, you can put some people in them now.
These are just standard sendmail list files - a list of addresses and/or
archive files, one per line.
