I'm troubleshooting authentication for my machine from RADIUS server which keeps on failing.

Latest findings showed that VSA attribute is configured on my machine as 1-byte however it is received from RADIUS server as 2-bytes (This was detected via tcpdump), as there is a leading Zero before that 1-byte which makes it 2-bytes.

My Idea to confirm those analysis are correct was to find a packet crafter tool that can intercept this packet before it is being processed by my radius client and remove the "0x0" before the VSA, Then, resend it to my machine so that it can be processed as expected.

I have no prior experience in Packet crafting, and even I've never know that such thing already exists before this idea to come to my mind.

Is this idea logic or real ? OR in other words, can this test be implemented ?
