Can I change uuid for network interface in ifcfg-eth* using uuidgen?

Question

i'm relativity new to delphi and trying to write a complex search algorithm for my a2 computing coursework. i need to access my record field from a string variable. e.g.

         getfield(record,'name');

I have found an article that may solve my problem but i cant make sense of it. please can someone shorten it down to just what i need. Thanks.

Solution

Yes, this article shows how. Keep NetworkManager in line, in case you use it.

Why don't you try first, and ask a question if you get stuck.

I have iv'e been trying for days now and i cant make sense of it im really just diving in the deep end here and i need a solution.

Since the record field is yours you probably need not RTTI to access it at all. RTTI is required to get information about the types unknown at compile time.

If you study my answer here, I'm sure you can figure it out: Convert Record to Serialized Form Data for sending via HTTP.

personally i don't see why not, i usually clone the ifcfg-* file and do the same.

Thanks @Rabin. Is it necessary to generate the UUID based on the mac address or it doesn't matter?

[LU RD]

@Serg, the field name could be unknown at compile time.

I'm glad I was able to help. You can easily expand this to support more complex record fields. :) Just have a look at the reference I've used here and you should be able to figure it out in a flash.

The article is correct that uuidgen will generate a new UUID that can be included in the ifcfg-x file. However, including the device name with uuidgen doesn't do anything at all. To answer the OP's question, yes, you can use any UUID value (generated by uuidgen or otherwise).
