[Buildbot-devel] Few problems in configuring BuildBot

  I have configured Master and Slave with little changes to "master.cfg"
file.  I am facing following 2 problems.  Could you please let me know, what
is causing this problem?

1) BuildURL(http://master:8010) is only accessible from master server.  If I
try to access this from Slave or any other machine, I am getting error
"connection refused when attempting to contact master:8010".  How can I make
this link accessible to slave and on other machine ?

2) Slave is not getting connected to master.  The "twistd.log" has the
following gets repeated many times

*2006/01/30 20:02 EST [-] Starting factory
<buildbot.slave.bot.BotFactoryinstance at 0xb7be5a8c>

*2006/01/30 20:02 EST [Uninitialized]
<twisted.internet.tcp.Connectorinstance at 0xb7be5b6c> will retry in 2

*2006/01/30 20:02 EST [Uninitialized] Stopping factory <
buildbot.slave.bot.BotFactory instance at 0xb7be5a8c>*

I have attached the configuration file (master.cfg), with this mail.  Please
let me know how to resolve the above errors ?

# This is a sample buildmaster config file. It must be installed as
# 'master.cfg' in your buildmaster's base directory (although the filename
# can be changed with the --basedir option to 'mktap buildbot master').

# It has one job: define a dictionary named BuildmasterConfig. This
# dictionary has a variety of keys to control different aspects of the
# buildmaster. They are documented in docs/config.xhtml .

import os.path
#from buildbot.changes.freshcvs import FreshCVSSource
from buildbot.scheduler import Scheduler
from buildbot.process import step, factory
from buildbot.status import html
s = factory.s

# This is the dictionary that the buildmaster pays attention to. We also use
# a shorter alias to save typing.
c = BuildmasterConfig = {}

# the 'bots' list defines the set of allowable buildslaves. Each element is a
# tuple of bot-name and bot-password. These correspond to values given to the
# buildslave's mktap invocation.
c['bots'] = [("slave1", "slave123")]

# the 'sources' list tells the buildmaster how it should find out about
# source code changes. Any class which implements IChangeSource can be added
# to this list: there are several in buildbot/changes/*.py to choose from.

c['sources'] = []

# For example, if you had CVSToys installed on your repository, and your
# CVSROOT/freshcfg file had an entry like this:
#pb = ConfigurationSet([
#    (None, None, None, PBService(userpass=('foo', 'bar'), port=4519)),
#    ])

# then you could use the following buildmaster Change Source to subscribe to
# the FreshCVS daemon and be notified on every commit:
#fc_source = FreshCVSSource("cvs.example.com", 4519, "foo", "bar")

# or, use a PBChangeSource, and then have your repository's commit script run
# 'buildbot sendchange', or contrib/svn_buildbot.py, or
# contrib/arch_buildbot.py :
#from buildbot.changes.pb import PBChangeSource

## configure the Schedulers

c['schedulers'] = []
c['schedulers'].append(Scheduler(name="all", branch=None,

# the 'builders' list defines the Builders. Each one is configured with a
# dictionary, using the following keys:
#  name (required): the name used to describe this bilder
#  slavename (required): which slave to use, must appear in c['bots']
#  builddir (required): which subdirectory to run the builder in
#  factory (required): a BuildFactory to define how the build is run
#  periodicBuildTime (optional): if set, force a build every N seconds

# buildbot/process/factory.py provides several BuildFactory classes you can
# start with, which implement build processes for common targets (GNU
# autoconf projects, CPAN perl modules, etc). The factory.BuildFactory is the
# base class, and is configured with a series of BuildSteps. When the build
# is run, the appropriate buildslave is told to execute each Step in turn.

# the first BuildStep is typically responsible for obtaining a copy of the
# sources. There are source-obtaining Steps in buildbot/process/step.py for
# CVS, SVN, and others.

# if you set 'debugPassword', then you can connect to the buildmaster with

# manually force builds and inject changes, which may be useful for testing
# your buildmaster without actually commiting changes to your repository (or
# before you have a functioning 'sources' set up). The debug tool uses the
# same port number as the slaves do: 'slavePortnum'.

# interactive python shell, which may be useful for debugging buildbot

c['projectName'] = "Buildbot"
c['projectURL'] = "http://buildbot.sourceforge.net/"

# the 'buildbotURL' string should point to the location where the buildbot's
# internal web server (usually the html.Waterfall page) is visible. This
# typically uses the port number set in the Waterfall 'status' entry, but
# with an externally-visible host name which the buildbot cannot figure out
# without some help.
