Well, Will, I'm learning more from you .... again ....

will  be replaced anyway as part of the Injoy ML> connection process.

 WH> Mike, be careful with that statement - I still haven't confirmed what
 WH> file sequence the JVM uses - but it DOES do a DNS lookup and it DOES
 WH> cache addresses.  I've had to fight PolarBar over that one while I was
 WH> on the road using multiple dialup numbers as I went from place to
 WH> place.  Only know cure for JAVA apps on a re-lease where DNS changes is
 WH> to shut it down and restart ;-{

Uh-oh.

 WH> Bob Eager had an interesting comment on usenet the other day about
 WH> resolv? files.  He refered to an RFC that seemed to say that the
 WH> convention was that the stack used resolv, reslov1, resolv2 etc. etc in
 WH> sequence until it found a working DNS.

Yes.  I'm trying to coordinate both forums here with what I'm learning, and
posting between who's here and who's in the usenet forums only.  I've tried to
be very careful not to post there until I really think I know enough.  And I
still stick my paw in my muzzle pretty often.  Grassburs are so icky to a puppy
dog, grin!

 WH> HEARSAY MODE ON:  While OS/2
 WH> allows you to only set up 2 nameserver - primary and alternate - the
 WH> stack will actually use up to 3, cycling thru in the order they appear
 WH> in resolv?

I actually thought about trying that by hand here to see if that would solve
the problem between the local server and the Tyler home server!  Hadn't done it
yet.  But now that you have said this, if I could find another even remote
server off IP to use for bailout, that might even be a better way to use this!
Or maybe far worse; see later thought here.

 WH> I have to do some digging, but it looks like the stack itself uses
 WH> some sort of resolv? to handle any servce DNS service request - I know
 WH> that the socket libraries do NOT require a nameserver URL in the API
 WH> call sequence.

TCP/IP stack here, right?

 WH> OK, now what do you do if  the Tyler center gets blown down by those
 WH> gentle Texas breezes laughingly refered to as tornadoes???

Yes .. at the last FidoNet Region 19 Lake party Net 117 hosted years ago here
at Sommerville Reservoir, the whole crew watched in horror as one of them
things vaccumed out the water in the lake and headed for the campsite! Then at
the last minute it took off on a different vector and the whole Region 19 crew
was spared.  What a precedent event for the wedding there between two of the
Region 19 folks that followed!  Talk about Hemningway and the Earth moving,
wide grin.

And as you know, though not Oklahoma, this is still the tail end of tornado
alley and the season is just starting for this year.  I still remember one of
our 18 wheeler's coming back from Pittsburgh with a full load of axles out at
the trailer company.  The driver called in all excited and said, "I've seen a
tornado!"  Mrs. Langston, originally from Pauls Valley, OK, replied, "So?" The
driver said back, "No, real close.."  She paused, asked, "How close?"

He then told her, "Well it picked up the whole truck and trailer when I was
going down the road on the divided highway just out of Big Cabin,  It spun me
around and around up in the air.  When it put me down, it put me down on the
other side of the divided highway, right in the road and I was going 65 miles
an hour back the other direction to Big Cabin.  Whole load is fine."

The event was witnessed by others....

 WH> In-Joy has resisted my efforts to force the third one in from the
 WH> get-go, but I have an "after connect" script that I run to insert a
 WH> third (public) nameserver into resolv and it has gone thru the first
 WH> two a few times.  In fact, I tested by using 2 bogus DNS addresses and
 WH> dialup did in fact fall back to the third one I inserted.

Which is an extension of what I tried to force connection to another DNS server
ahead of the COX stuff!  And .. that leads me to a very interesting question
here, at least to me.

 WH> Sometimes you eat the bear, sometimes he eats you <g>.

Bearly able, but still trying, I choose to take these footprints somewhere else
now.

What is to stop anyone, from a virus infection standpoint, from simply plunking
in "resolv" with a carefully chosen DNS server that you have no idea is being
used?  Heck, you can write CONFIG.SYS to your heart's content unrestricted in
OS/2.  And AUTOEXEC.BAT, unless, by chance, sly grin, you haven't put in the
fix for the big DHCPCD mess?  Then what is to stop the use of the carefully
corrupted DNS server from hijacking a DNS lookup for a specific address, such
as M/S or whatever, to a different URL site which, in the current fashion of
corruption, looks exactly like what you think you want, but under the surface
is using JAVA for all kinds of evil purposes?

Inquiring mind wants to know.  Even one not yet addicted to coffee .
