Hi @glaslos,

I wanted to pick up this issue. As far as I could read about the following protocol, I understood that I need to extract the first 48 bytes, as the header and the remaining as the data that the request carries. Since it is carried over the TCP/IP connection, we can set up a listener on the given port and then parse the request, just like the existing one for HTTP etc.

Is this something that needs to be done? Kindly guide!

You only need to implement a handler, have a look here

@glaslos
I implemented a handler for iSCSI. Currently it parses and gives responses for 3 opCodes as given in - https://www.iana.org/assignments/iscsi-parameters/iscsi-parameters.xhtml. I have not tested it yet with a sample iSCSI request.

Could you review it once?
