In my network every subnets default gateway is X.X.X.1. That router
gateway is always running ntpd which I want to give be default as the ntp
server in every hosts ntp.conf.
Since there is no official "default gateway" fact yet, what I want to
be
able to do in my manifest is take the $ipaddress fact and turn it into the
gateway for that subnet.
For example...
IP = 10.1.1.12
GW = 10.1.1.1
I''m using the puppetlabs-ntp module, so I should be able to do
something
like this in my classes...I think... I just need to know how to get the .1
address in there...
class mycustomclass:ntp {
class { "ntp":
servers => [ DOT_ONE_ADDRESS_FOR_HOSTS_IP_GOES_HERE ],
autoupdate => false,
}
}
If this was raw ruby I could do some string magic to turn the last value to
1. I don''t know how to do that with the Puppet DSL though.
Thanks,
Matt

Oh, look. I get to be useful! I''ve done something similar for my
computer
cluster class. I base the ip of the eth4 interface off the ip of eth0,
changing one octet from 39 to 38. Here''s the line:
$eth4ip = regsubst($::ipaddress_eth0, ''\.39\.'',
''.38.'')

$ntpip = regsubst($::ipaddress, ''[0-9]+$'',
