Hi, I have a template named rsyslog.conf.erb, and the puppet agents seem to be choking on this: **.notice;news.none;cron.none @loghost:514* The agents report an error of ": bad URI(is not URI?): " followed by a bunch of jargon. I''m pretty sure its the literal ''@'' symbol that its trying to evaluate as erb code. How can I escape this @ symbol so its a literal?

[Puppet Users] Re: Literal @ character in erb template
Hi, I am not sure how your template looks like, or how do you render it, but try to avoid putting anything with @ into a <%= %> block. It should just work: matti@acrux ~ $ irb>> require ''erb''=> true>> host = ''localhost''=> "localhost">> p ERB.new(''*.notice;news.none;cron.none @<%= host%>:514'').result(binding) "*.notice;news.none;cron.none @localhost:514" => nil>> @host = host.clone=> "localhost">> p ERB.new(''*.notice;news.none;cron.none @<%= @host%>:514'').result(binding) "*.notice;news.none;cron.none @localhost:514" => nil>>matti@acrux ~ $ cat | puppet apply --noop notice inline_template(''*.notice;news.none;cron.none @<%= @hostname %>:514'') notice: Scope(Class[main]): *.notice;news.none;cron.none @acrux:514 notice: Finished catalog run in 0.03 seconds matti@acrux ~ $ KW On Friday, 31 August 2012 15:09:17 UTC+1, banjer wrote:> > Hi, > I have a template named rsyslog.conf.erb, and the puppet agents seem to be > choking on this: > > **.notice;news.none;cron.none @loghost:514* > > > The agents report an error of ": bad URI(is not URI?): " followed by a > bunch of jargon.

Thanks for the reply KW, but thats not quite what I was asking. Heres the relevant section of the template: *.notice;news.none;cron.none @loghost:514 <% if @hostname == "foo" %> # Provides UDP syslog reception $ModLoad imudp.so $UDPServerRun 514 <% end %> So you can see it lives outside of a <% %> block. This part: "*.notice;news.none;cron.none @loghost:514*" *should be a literal string. Its a standard rsyslog configuration. "Loghost" is the actual hostname of a host in our network that we send all of our servers'' syslogs to. In other words, I don''t want it to be evaluated as ERB code. So how can I have puppet/the template engine ignore the ''@'' symbol and treat it as a literal string?

Hi,
Works fine for me:

# Provides UDP syslog reception
$ModLoad imudp.so
$UDPServerRun 514
<% end %>
matti@acrux ~ $ sed -i ''s/foo/acrux/'' test.erb
matti@acrux ~ $ cat | puppet apply
file { ''/tmp/test.txt'':
content => template(''/tmp/test.erb'')
}
notice: /Stage[main]//File[/tmp/test.txt]/ensure: defined content as

The puppet error was:
err: Failed to apply catalog: Parameter source failed: Could not
understand source # This file managed by Puppet
Sorry for not seeing that error before...I kept looking at the "Bad
URI"
error message which I posted in my original email. So anyway, it turns out
I was using ''source'' instead of ''content''
within my file declaration in my
manifest. My working file resource looks like this now:
file { "rsyslog.conf":
path => "/etc/rsyslog.conf",
owner => root,
group => root,
mode => 644,
content =>
template(''syslog/rsyslog.conf.erb''),
require => Package["rsyslog"],
}
All good now. Thanks for the assistance, it gave me a few pointers on
troubleshooting templates and puppet manifests.

The problem isn''t the loghost line. Your if statement clearly uses a @ character before hostname. I suspect that this is your only problem, and removing the @ will solve your problem. -- Jo Rhett Net Consonance : net philanthropy to improve open source and internet projects. -- You received this message because you are subscribed to the Google Groups "Puppet Users" group.

Jo, I did figure it out, not sure if you saw my last post on this. Per my last post I said, "it turns out I was using ''source'' instead of ''content'' within my file declaration in my manifest." So it had nothing to do with the erb file at all. Regarding the @ symbol, it was a red herring. In fact, I have the "<% if @hostname == "foo" %>" statement in a bunch of different templates in several of my puppet modules, and that statement works beautifully.
