Faulty time-response from 64bit server (Motorola -> choke)

Dears Sirs,

We're a cable/broadband/mobile-transmission/etc company who has developed a full solution for management and monitoring of Docsis broadband networks.

For ToD we're using the internal UDP-server in Linux.

Just recently we installed the application on a 64bit machine (running Ubuntu server).
There seems to be a problem with the ToD-response, the Motorola CMs doesn't accept it.

The response is (not identical timestamp):

from 64bit server:

0000 00 19 56 c9 99 3c 00 14 5e b4 6e c0 08 00 45 00 ..V..<.. ^.n...E.
0010 00 24 00 00 40 00 40 11 11 1b c1 16 5e 04 0a 0a .$..@.@. ....^...
0020 00 8a 00 25 05 05 00 10 29 d0 ca 59 60 7a 00 00 ...%.... )..Y`z..
0030 00 00 ..

from 32bit server:

0000 00 00 ca bb f0 5d 00 14 85 30 e8 7d 08 00 45 00 .....].. .0.}..E.
0010 00 20 00 ee 40 00 40 11 cb 74 ac 00 0b 03 ac 00 . ..@.@. .t......
0020 0b 67 00 25 05 c9 00 0c 2c b5 ca 59 94 6e .g.%.... ,..Y.n

There are 4 extra bytes of 0 in the response from the 64bit server. I guess this is what is making Motorola choke. The timestamp is the "ca 59 94 6e" value.

I haven't been able to test with other CMs yet, but will soon.

If anyone has any thoughts, tips, solutions, feel free to join in ;)

TOD

Not sure what port your serves uses for TOD, but per rfc 868 for docsis my system uses port 37. I've enable it for udp and tcp just in case
