Brent -
Those OS'es are 13 and 14 years old, respectively. I'm all for stable but we certainly don't test on them :) I've sent a note to engineering, I'll let you know what they say about UDP support.

Alas, that does not work on Solaris 2.6 or 7. Solaris 7 was apparently
the first to support the WebNFS URL syntax, but it otherwise has the same
behavior as 2.6. Both seem to be hardwired to look for the UDP mountd
port, even when told to use TCP. On each, you can specify the NFS port,
but apparently not the mountd port (there's no mountport option
documented).
Perhaps they got it right in Solaris 8 or greater, at least for WebNFS,
but I no longer have any newer Solaris with which to test...
Thanks,
Brent
