[Puppet Users] Puppet doesn''t work over slow connections?

Hi all,

I''m trying to do exactly the same thing as described on this bug
report, and
I''m having exactly the same problem:

   http://projects.puppetlabs.com/issues/4762

The bug report seems to suggest that "editing the line on the puppet
master"
will fix the problem, but I don''t know what this means.  Is this the 
configtimeout or filetimeout config option?

At the moment this is all I get when connecting to a puppetmaster (which works 
fine with hosts on the same LAN, but this server is on the other side of the 
world, ping time approx 175ms):

# puppetd --server localhost --waitforcert 60 --test
warning: peer certificate won''t be verified in this SSL session
err: Could not request certificate: SSL_connect SYSCALL returned=5 errno=0 
state=SSLv2/v3 read server hello A

After this the server says:

[2010-12-29 09:57:28] ERROR RuntimeError: Client disconnected before 
connection could be established
         /usr/lib/ruby/site_ruby/1.8/puppet/network/http/webrick.rb:43:in

         /usr/lib/ruby/site_ruby/1.8/puppet/network/server.rb:142:in
`start''
         /usr/lib/ruby/site_ruby/1.8/puppet/daemon.rb:124:in `start''
         /usr/lib/ruby/site_ruby/1.8/puppet/application/master.rb:114:in
`main''
         /usr/lib/ruby/site_ruby/1.8/puppet/application/master.rb:46:in 
`run_command''
         /usr/lib/ruby/site_ruby/1.8/puppet/application.rb:287:in `run''
         /usr/lib/ruby/site_ruby/1.8/puppet/application.rb:393:in

         /usr/lib/ruby/site_ruby/1.8/puppet/application.rb:287:in `run''
         /usr/bin/puppetmasterd:4

I assume the connection is working then, because if I try to telnet to port 
8140 on the puppetmaster I get disconnected before I can type a single letter. 
  Normally you get a few minutes before getting disconnected, so either
it''s
not working or the timeout defaults to a value far too low for Puppet to work 
when the servers are a long distance apart.

Any suggestions as to how I might get Puppet working with hosts on different 
continents?

Many thanks,
Adam.

Adam, can you vote or watch that bug please so we know other people
are being affected by it?

Updating the worklog to also say "I''m having this problem under
these
conditions" also lets the person who it is assigned to know that
it''s
still an issue, and is affecting more than just the original reporter.

It''s actually suggesting that you edit the puppet source code.
Obviously this is not a long term solution, but it would be very
helpful if you had success doing this and could let us know in the
ticket.

Depending upon your platform and installation, the puppet source code
may live in various locations, but it''s likely to be something like:

/usr/lib/ruby/site_ruby/1.8/puppet/network/http/webrick.rb
or
/usr/lib/ruby/1.8/puppet/network/http/webrick.rb

Are you actually using webrick as the puppet master? We do highly
suggest that people set up Passenger or Mongrel with Apache for
production environments, as webrick hits scalability limits rather
quickly.


http://projects.puppetlabs.com/projects/1/wiki/Using_Passenger
http://projects.puppetlabs.com/projects/puppet/wiki/Using_Mongrel

That''s not to suggest this shouldn''t be resolved for webrick
however.> At the moment this is all I get when connecting to a puppetmaster (which

Ah, of course - I tried this and it did solve the problem for me.

Yes I''m using webrick.  I only have a small number of servers hanging
off this
puppetmaster with little chance of expansion so there are no scaling issues to 
worry about just yet.

But now it''s all working fine, so thanks for your help!

Cheers,
Adam.
