> We are running SRSS 4.2 on SLES 10 SP3 32-bit with 3 hosts in a FOG and

A little update here: we missed to install patch 140995-01 - it included
a promising fix for bug '6918519 Restore "forced callme" feature to DM'.

Unfortunately installing this patch did not resolve the problem (but at
least we now have a shiny new FW 4.2_140993-01_2010.01.21.17.35 on our
DTUs).

But our firewalls detected strange traffic:
as mentioned above, we have a dedicated interconnect setup with
registered IPs for Sunray-traffic, so each of our FOG-hosts has two NICs
called eth0 and eth3, eth0 for normal lan traffic (with shared lan
interconnect turned off) and eth3 for Sunray-Traffic.

Let's assume the following addresses:

primary server:
eth0: x.y.z.151
eth3: a.b.c.1

secondary server 1:
eth0: x.y.z.152
eth3: a.b.c.2

secondary server 2:
eth0: x.y.z.153
eth3: a.b.c.3

tcpdump on the primary server now shows various connection attempts of
the local utdevmgrd to 2.c.b.a:7011 and 3.c.b.a:7011, the secondary
server 1 tries to reach 1.c.b.a:7011 and 3.c.b.a:7011, finally secondary
server 2 pumps out connection attempts to 1.c.b.a:7011 and 2.c.b.a:7011.

So every machine tries to connect to the utdevmgr of the other two peers
but uses a target IP with REVERSED byte order.
Of course this traffic leaves on the wrong interface via default route
and bothers helpless machines somewhere in the world, but never reaches
the intended target (in fact, it doesn't do so any longer, we blocked it
on our GW).

Fixing this bug is beyond our capability (little-big-endian-problem
during SPARC-to-linux-port?), so I'd like to file a bug report, but
http://bugreport.sun.com seems to only be related to JAVA-stuff and
tells me to "review ... paid support options below".

How do I properly submit this problem to someone able to help?

Thanks in advance,
a nice weekend to the community,

Nico
