Second version.

the defs file. Re-arranged some of the existing snippets to make it
somewhat more cohesive, though it could still use a lot more work in
this area. Also, moved all of the remaining stuff about what to copy
from an old boss node (which was the original purpose of the document)
to the end, so that it's more geared toward people setting up their
own boss.

Still needs some documentation (and probably a script for auto-generating)
DNS config files.

consistent 0ms when the intent is no delay, and add an explantion of
what 0ms means (no darling, it doesn't mean that packets travel
through an ethernet wormhole).

the new image stuff. Also fix a minor logic error in dbcheck that was
causing it to break on the failed queries instead of moving onto the
next one.

users by appending a simple path command to the new .cshrc and
.profile when the account is first created. Easiest approach, albiet
an imperfect one.

tb-set-node-os and another explanation in the OS descriptor list
page. Yes, its clear that the distinction between imageIDs and OSIDs
is just plain confusing.

invoked from os_setup, which runs as the user.

modified, even by an admin type.

line in all email from the system. Remove all of the TESTBED: tags
and modify the email function in the web server and perl library to
prepend @DOMAIN@: to the message.

getTrunks: Build a structure representing all of the trunks in the switch
	topolgy
getTrunkPath: Find the shortest path between two switches, across the
	trunks found by getTrunks

Note that the getTrunkPath duplicates some work done in assign. However, we
don't currently have a good way to pass this information from assign to
snmpit, and we need to be able to figure this out anyway, in case snmpit
isn't being called as part of experiment swapin.

These functions should soon be used to pick which VLANs are allowed
across which trunks.

Update pages appropriately. Also cleanup up a few more sub menus.

a node is not allocated (thus putting the .acl and .run file into the
wheel group when capture creates them), return the value of the config
variable TBADMINGROUP (which is flux for us). This makes it easier for
admin people to look at free nodes.

STDOUT, and move around some lines to avoid undefined value
warnings.

since that screws up opera (and is incorrect anyway). Add wrapper code
to the docwrappers to include the html header/trailer code when
doing a printable version, and include the proper style sheet.

whatever other maintenance is required.

naming scheme was not very intuitive and the names sucked. Also, I
want to increase the frequency with which we run the backups, and I
want to implement an automated roll so that we only keep about a
months worth of history around.

Anyway, the new approach is to open up the index file and see what the
name of the current update file is. It has a numeric extension. Rename
the base log to base.XXX, and then snapshot the DB into backup.XXX So,
the combination of update.XXX and base.XXX is the DB history since the
last time the script was run. The file backup.XXX corresponds to the
DB at this point in time.

To restore (or track the changes of) a DB, simply take backup.XXX and
apply the changes that are stored in update.XXX+1 (which are the changes
made since backup.XXX was made). This should give you a DB that is the
same as backup.XXX+1. You can go back further, and just apply all the
subsequent update.XXX files.

very useful by itself anyway.

supporting autocreating and autoloading images. The imageid form now
sports a field to specify a nodeid to create the image from; If set,
the backend create_image script is invoked. Thats the easy part.
Slightly harder is autoloading images based on the osid specified in
the NS file. To support this, I have added a new DB table called
osidtoimageid, which holds the mapping from osid/pctype to imageid.
When users create images, they must specify what node types that image
is good for. Obviously, the mappings have to be unique or it would be
impossible to figure it out! Anyway, once that image mapping is
in place and the image created, the user can specify that ID in the NS
file. I've changed os_setup to to look for IDs that are not loaded,
and to try and find one in the osidtoimageid. If found, it invokes
os_load. To keep things running in parallel as much as possible,
os_setup issues all the loads/reboots (could be more than a single set
of loads is multiple IDs are in the NS file) at once, and waits for
all the children to exit. I've hacked up os_load a bit to try and be
more robust in the face of PXE failures, which still happen and are
rather troublsesome. Need an event system!

Contained in this revision are unrelated changed to make the OS and
Image IDs per-project unique instead of globally unique, since thats a
pain for the users. This turns out to be very messy, since underneath
we do not want to pass around pid/ID in all the various places its
used. Rather, I create a globally unique name and extened the OS and
Image tables to include pid/name/ID. The user selects pid/name, and I
create the globally unique ID. For the most part this is invisible
throughout the system, except where we interface with the user, say in
the web pages; the user should see his chosen name where possible, and
the should invoke scripts (os_load, create_image, etc) using his/her
name not the internal ID. Also, in the front end the NS file should
use the user name not the ID. All in all, this accounted for a number
of annoying changes and some special cases that are unavoidable.

page.

Netscape and IE both recognize it:

	<input type=readonly ... >

The correct way is:

	<input readonly type=text ...>

Hmm.

Fix up SUEXEC and TBERROR error handling so that <XMP> tags are not
included in the email message!
Add CHECKURL() function (which will eventually replace VERIFYURL())
which returns error strings instead of calling USERERROR. This is
in support of new forms code.
Add CHECKPASSWORD() function; same code was in three different places.
This version returns the error string from checkpass.

finished.

file. Controls whether we spit out the keywords and the emu page,
since we do not want anyone but else getting the links.

Also moved the picture to make the text look better.

gets spit out a lot in all of the pages (http or https).
Refine fonts and little bits in the banner.
