This beta release is quite new, and is running in production at only a
|
|
|
|
|
few sites. We strongly recommend that you exercise caution in
|
|
|
|
|
installing it. The 3.0 Beta 2 lease file is not backwards compatible
|
|
|
|
|
with the 3.0 Beta 1 lease file, so if you have to go back, you will
|
|
|
|
|
have to convert your lease files back to the 3.0 Beta 1 format - if
|
|
|
|
|
you try to run a 3.0 Beta 1 server on a 3.0 Beta 2 lease file, it will
|
|
|
|
|
cheerfully delete all your leases. Having said that, of course the
|
|
|
|
|
way that new releases of open source software become stable is by
|
|
|
|
|
people using them, finding the bugs, and reporting the bugs. So
|
|
|
|
|
while we urge you to exercise caution, we would also appreciate any
|
|
|
|
|
testing or production use you can safely do.

The Dynamic DNS Update support is a descendent of an implementation
|
|
|
|
|
done by Lans Carstensen and Brian Dols at Rose-Hulman Institute of
|
|
|
|
|
Technology, Jim Watt at Perkin-Elmer, Irina Goble at Integrated
|
|
|
|
|
Measurement Systems, and Brian Murrell at BC Tel Advanced
|
|
|
|
|
Communications. I'd like to express my thanks to all of these good
|
|
|
|
|
people here, both for working on the code and for prodding me into
|
|
|
|
|
improving it.

Changes since 3.0 Beta 2 Patchlevel 4
|
|
|
|
|
|
|
|
|
|
- Incorporated Peter Marschall's proposed change to array/record
|
|
|
|
|
parsing, which allows things like the slp-agent option to be encoded
|
|
|
|
|
correctly. Thanks very much to Peter for taking the initiative to
|
|
|
|
|
do this, and for doing such a careful job of it (e.g., updating the
|
|
|
|
|
comments)!
|
|
|
|
|
|
|
|
|
|
- Added an encoding for the slp-agent option. :')

|
|
|
Changes since 3.0 Beta 2 Patchlevel 3
|
|
|
|
|
|
|
|
|
|
- In the DHCP client, execute client statements prior to using the values
|
|
|
|
|
of options, so that the client configuration can overried, e.g., the
|
|
|
|
|
lease renewal time.
|
|
|
|
|
|
|
|
|
|
- Fix a reference counting error that would result in very reproducible
|
|
|
|
|
failures in updates, as well as occasional core dumps, if a zone was
|
|
|
|
|
declared without a key.
|
|
|
|
|
|
|
|
|
|
- Fix some Linux 2.0 compilation problems.
|
|
|
|
|
|
|
|
|
|
- Fix a bug in scope evaluation during execution of "on" statements that
|
|
|
|
|
caused values not to be recorded on leases.
|
|
|
|
|
|
|
|
|
|
- If the dhcp-max-message-size option is specified in scope, and the
|
|
|
|
|
client didn't send this option, use the one specified in scope to
|
|
|
|
|
determine the maximum size of the response.

|

|
|
|
Changes since 3.0 Beta 2 Patchlevel 2
|
|
|
|
|
|
2000-09-08 01:40:51 +00:00
|
|
|
- Fix a case where spawning subclasses were being allocated
|
|
|
|
|
incorrectly, resulting in a core dump.
|
|
|
|
|
|
2000-09-08 01:37:15 +00:00
|
|
|
- Fix a case where the DHCP server might inappropriately NAK a
|
|
|
|
|
RENEWING client.
|
|
|
|
|
|
|
|
|
|
- Fix a place dhcprequest() where static leases could leak.
|
|
|
|
|
|
|
|
|
|
- Include memory.h in omapip_p.h so that we don't get warnings about
|
|
|
|
|
using memcmp().

|

|
|
Changes since 3.0 Beta 2 Patchlevel 1
|
|
|
|
|
|
|
|
|
|
- Notice when SIOCFIGCONF returns more data than fit in the buffer -
|
|
|
|
|
allocate a larger buffer, and retry. Thanks to Greg Fausak for
|
|
|
|
|
pointing this out.
|
|
|
|
|
|
|
|
|
|
- In the server, if no interfaces were configured, report an error and
|
|
|
|
|
exit.
|
|
|
|
|
|
|
|
|
|
- Don't ever record a state of 'startup'.
|
|
|
|
|
|
|
|
|
|
- Don't try to evaluate the local failover binding address if none was
|
|
|
|
|
specified. Thanks to Joseph Breu for finding this.
