I'm stuck trying to remove the ":" chars from the string.

try something like: if ( &Calling-Station-Id =~ /^([0-9a-f]{2})-([0-9a-f]{2})-([0-9a-f]{2})-([0-9a-f]{2})-([0-9a-f]{2})-([0-9a-f]{2})$/i ) newusername = "%{1}:%{2}:%{3}:%{4}:%{5}:%{6}"

The example in the docs for regex is a username comparison (first google hit), and there are many examples all over stackexchange of mac address regexes.

And yes, it's often used. Greetings Hermann

Are you stuck on where to do the username comparison, or how to remove the :'s from the string or ?

Hello,

I have a scenario where I need to modify User-Name, before any AAA operation, based on a regex substitution. To be precise, the users are sending a MAC as the username, in the form "00:11:22:33:44:55" and I need to transform this to "001122334455".

This may be a silly question, but I haven't found how to do it. Is there any way to do it? Thank you.
