Welcome to the club Pete!

I assume the "Cobalt" server you are talking about is a Sun running some 
version of Solaris.

If you want to use a GPS receiver with NTP 4.2.0, you may need to get a 
more recent version of the code than what I downloaded Jan 4, 2004.  
There have been a number of fixes since then, one of which corrected 
errors in the Motorola Oncore driver that prevented it from building 
properly under Solaris 8.  Of course, if you don't get a Motorola 
Oncore, that probably will not affect you.

I'm not familiar with the Cobalt and its software but I suspect that if 
you put the executables in the same directories, using the same file 
names, that it should work as it did before.  You should be aware that 
the semantics of the restrict statement changed between 4.1 and 4.2.; 
one of the flags, I believe it's "notrust" has a different meaning.

Read the docs and you should be able to "muddle through" the same as the 
rest of us.  If you have questions, somebody around here probably has
