Hello everybody, for my Case I needed to change one Octett of my NAS-IP-Address ( like from x.x.4.x to x.x.5.x )!
In what way did you want to change the third octet? Only replace 4 with 5? Replace any value with that value plus one?
I don't really found an function to change only one octett from the NAS-IP-Address
Sure, you can easily do it in unlang. For example to change x.x.4.x to x.x.5.x: if (NAS-IP-Address =~ /^([0-9]+\.[0-9]+)\.4\.([0-9]+)$/) { update request { NAS-IP-Address := "%{1}.5.%{2}" } } If you wanted to add 1 to an octet you can use the expr module to do that, e.g. %{eval: %{2} + 1}. See 'man rlm_expr' for more examples. Anyway, this is really a user question not a devel question. Regards, Brian.
