I brought my home Sun Ray into the office to upgrade its firmware to 4.0_48_2007.08.01.15.48. This was successful and quite easy to do. Unfortunately, it had no effect on the problem I've been observing. > Is perhaps something blocked by the NAT router? I'm using ipfilter in > Solaris 10 8/07 for this.

Just as I got a glimse of the Windows window and heard the Microsoft arpeggio, I got that timeout again. I had to control-moon the Sun Ray and unlock my screen to recover. Is something happening at this point that doesn't make it through the NAT router? -- -Gary Mills- -Unix Support- -U of M Academic Computing and Networking- _______________________________________________ SunRay-Users mailing list [email protected] http://www.filibeto.org/mailman/listinfo/sunray-users
