Ladies and Gentlemen,

I had only one response to my query, from Timothy
Lindgren who apparently doesn't have the problem
I do. I've managed to delay the decision for a
little while and am still trying to resolve the
problem.

Original statement of problem below in case
anyone may have missed the original.

> Ladies and Gentlemen,

> I have a Sun Ultra5 with a SunPCi card that I was asked to
> do an evaluation of for possible deployment. The U5 is
> running 2.6 with appropriate patches and the SunPCi is
> running M$ W95SR2. All basic stuff looks fine (except for
> color flashing - 19" monitor at 1280x1024 can only run
> 8bit color).

> I've been beating on this for a few days and the time
> to make a recommendation is coming up fast.

> The problem is with the workstation and SunPCi seeing
> each other on the network. In the SunPCi Release Notes,
> item 16 this problem is discussed. I tried the approach
> and it doesn't work. I'm not sure part of it (PC side)
> even makes sense.

> In the following:
>
> a.b.70.1 router
> a.b.70.49 SunPCi
> a.b.70.91 U5 workstation
>
> State before trying to set specific routes per Sun suggestion

> On the workstation - routing table

> (add a route to the workstation through the router,
> but with a mask as if it's a route to a network)

> This does not change the PC routing table.

> Now if I ping from the workstation to SunPCi or vice versa, the first

> a.b.70.49 a.b.70.49 UGHD 0 3
>
> that hangs around for several seconds and then disappears. After which
> I can get a single ping through again.

> So, is Sun confused? At this point I know I am. Have you gotten this
> to work or just ignored the problem?

> Thanks in advance, summary will follow.
