Wouldn't it be a bit cleaner to use the builtin regsubst function? http://docs.puppetlabs.com/references/latest/function.html#regsubst "Example: Get the third octet from the node’s IP address: $i3 = regsubst($ipaddress,'^([0-9]+)[.]([0-9]+)[.]([0-9]+)[.]([0-9]+)$','\3')" I really try to avoid inline_template unless I absolutely have to, even though the actual Ruby code there is cleaner than the long regex. If you really only want the third octet, you could use a much simpler regex than the one above. Obligatory plug for the site I always use for regex references: http://www.regular-expressions.info as it's an easy domain name to remember. > For eg., > $nsip=inline_template('<%= ipaddress.split(".")[0..1].collect{|x| > x}.join(".") %>') > This will split an ip address, say 192.168.1.3, split it at each occurrence > of a "." and will join the first two numbers ( referenced as [0..1] ), to > give 192.168. > So, in your case, I guess something like <%= ipaddress.split(".")[1] %> > should work. > > > On Thu, Oct 14, 2010 at 7:27 PM, Dennis vdM <cybernijn...@gmail.com> wrote: >> >> I'm trying to manipulate the following facter variable: >> >> ipaddress => 10.85.207.2 >> >> What I need is the second group of digits.
