Wyse Options Problem (PXE Boot)

Hello,

I have no problem on ISC DHCP 4.2.5 for wyse clients but wyse options don't work on KEA 1.4.0-p1 version.

I was define wyse options; option 161 -> ftp url, option 162 -> ftp path, option 184 -> ftp user, option 185 -> ftp password

If I define just this options, dhcp server send offer but wyse client cannot send request. I am sure offer packet is received wyse client, I open debug on switch and I see received dhcp packets.

Wyse options configuration:

"option-def": [
    {
            "name": "wyse-ftp-config",
            "code": 161,
            "type": "string"
    },
    {
            "name": "wyse-ftp-path",
            "code": 162,
            "type": "string"
    },
    {
            "name": "wyse-ftp-user",
            "code": 184,
            "type": "string"
    },
    {
            "name": "wyse-ftp-password",
            "code": 185,
            "type": "string"
    }
],

"subnet4": [
	{
        "subnet": "10.0.100.0/24",
        "id": 1,
        "pools": [ { "pool": "10.0.100.50-10.0.100.55" } ],
        "option-data": [
							{
								"name": "routers", 
								"data": "10.0.100.254"
							},
							{
									"name": "wyse-ftp-config",
									"data": "ftp.example.com",
									"always-send": true
							},
							{
									"name": "wyse-ftp-path",
									"data": "ftppath",
									"always-send": true
							},
							{
									"name": "wyse-ftp-user",
									"data": "ftpuser",
									"always-send": true
							},
							{
									"name": "wyse-ftp-password",
									"data": "ftpuser",
									"always-send": true
							}
		]
	}
]

Offer packet for this condition:

      Your-IP x.x.x.x

      Gateway-IP x.x.x.x

      Client-Ethernet-Address xx:xx:xx:xx:xx:xx

      Vendor-rfc1048 Extensions

        Magic Cookie 0x63825363

        Subnet-Mask Option 1, length 4: x.x.x.x

        Default-Gateway Option 3, length 4: x.x.x.x

        Domain-Name-Server Option 6, length 8: x.x.x.x, x.x.x.x

        Lease-Time Option 51, length 4: 40

        DHCP-Message Option 53, length 1: Offer

        Server-ID Option 54, length 4: x.x.x.x

        RN Option 58, length 4: 10

        RB Option 59, length 4: 20

        MUD-URL Option 161, length 14: "ftp.example.com"

        T162 Option 162, length 15: xx.xx.xx.xx

        T184 Option 184, length 9: xx.xx.xx.xx.xx

        T185 Option 185, length 10: xx.xx.xx.xx.xx

        Agent-Information Option 82, length 17:

          Circuit-ID SubOption 1, length 6: xxxxxx

          Remote-ID SubOption 2, length 7: xxxxx

        END Option 255, length 0

If I add "boot-file-name" in subnet configuration, wyse client take IP when pxe boot. However, wyse client don't take wyse options, already I don't want to give boot-file-name. Normally, offer, request, ack packet didn't include wyse options.

Offer/ACK packet for this condition:

     Your-IP x.x.x.x

      Gateway-IP x.x.x.x

      Client-Ethernet-Address xx:xx:xx:xx:xx:xx

      file "example boot-file-name"[|bootp]

Do you chance try this options for wyse client? Maybe it is bug, maybe kea make problem for this options.

Thank you,

Best Regards.
