Basically most people said it could be done, with a couple saying that I
might be better off ftp'ing the files over. Since it didn't seem to
matter either way I tried NFS first. On one server the patch
installation went fine. On the other, geographically closer, server two
out of eight installations failed. I copied those files locally and
reapplied them successfully.

I have been using NFS over a router just fine. Go ahead and do it.

I've used that method for systems around the world -- just telnet or
rlogin into the remote machine -- ftp back to your system and get the .Z file
off the CD ( be sure to set binary mode ) and then do a normal install on the
remote system --- works well!!

I have done this over a 56 k DDS circuit with no problems except for taking
up a lot of bandwitdh and slowwing everyone down

Marco,
I have successfully applied patches to remote machines on my WAN using NFS through routers and 64K ISDN lines.
I have not done so from the Sunsolve CD but from disk as the patches were l.oaded from tape. I don't think this will make any difference though.

I've NFS mounted from some of our servers in Sweden. I'm in California. It works. Slow, though.

Why mount the CD-ROM? Just copy the patch file ...

I know what you mean! I was just considering doing it myself to apply some pates to 1 of our remote sites. I have a 56K link to it and yes I am going to attempt it. I don't think it will crap out, I just don't think you would want to dothis normally. I
even tried mounting over a dialup line (38400) once, but that was just for kicks and I do not have any statistics.

You're right, there is a problem using NFS through a router, but "ftp" works just fine. Use that to copy the files to the remote systems, then "rlogin" and install the patches.
Good luck,

Having done this via a VLLAN (Very Louzy LAN) which I think will simulate a WAN, I would advise ftping the the compressed tar file to the remote machine, zcat/tar it, and then installit, remove the patch directlory.
ALSO...I have noted (as in patch 101329-15) that the script is not written correctly, so that nfs mounted patching WILL fail. --

Marco,
This really depends on the speed of your WAN. We've done NFS over 1MB/sec WANS. It's not fast, but it is ok for something like this. I wouldn't go any slower. If NFS is to slow, why not use something like FTP? If you have a WAN connection of any speed, that is probably faster than overnight delivery.
BTW, what problems with NFS over routers are you refering to? We do NFS over routers all the time.

It can be done, but tends to be pretty slow over long hauls. EG, if you have /net setup as an ftp->NFS gateway, it's almost always quite noticeably slower than (relatively) raw ftp.
You may want to copy the data to a ufs on the far side of your link, and do the patches from there. rsh and gtar, or dump and restore, should do for the copy.

The only suggestion that I'ld make is to set your read and write packet size to something like 512 or even 256, I think just about every router uses packet sizes of 512 or greater. By setting your read and write packet size to 512 (actually maybe 450 to account for overhead) you'll get the best possible through-put without risking packet fragmentation.
The biggest problems with NFS over a WAN is that NFS doesn't deal well with packet fragmentation or lost packets. Unfortunately packet lost is not really something you can do much about, you either have a reliable connection or not.
