Because having OSPF is one thing, and having OSPF MULTI-CAST is quite another
issue.  Last I remember, OSPF Multicast is still in Draft state, as is the
MIB.  BTW, on the subject of Wellfleet - implementation of OSPF MIB has lagged
FAR behind that of OSPF itself.  Then the issue becomes - you can pass 
packets OK, but you want to MANAGE it too?? :-)

You may not get 100%, no. But modern workstations can get very close (say
better than 95%).

How about actually *measuring* instead? With tools like ttcp and a quiet
(two station) Ethernet, I can get better than 1 MByte/s (yes, 1048576 B/s)
between two Sparc IPCs. And you certainly can't claim they are top of the
line these days...

People seem fond of propagating the idea that you will never be able to fully
load an Ethernet. Well, you can! And despite theoretical predictions to the
contrary, Ethernet handles a high load very well, degrades gracefully and is
in general extremely reliable.

Well there's a couple of ways of doing what you want to do.  If your
gateway to the Internet is a router that can handle per-port filtering
(e.g. a cisco), then you can disallow packets coming into TCP port 23
(TELNET) or 513 (rlogin) (you might want to filter out 514 [rsh], 21
[FTP] and who knows what.)

If you don't have that capability, you can put the filtering burden
on all your hosts.  Get a TCP/UDP master server that's capable of
disallowing connects on a per-IP-address basis, such as TGV's
MultiNet (VMS only) or the TCP_WRAPPER program on cert.sei.cmu.edu
in pub/network_tools/tcp_wrapper.

The answer to this is specific to your FTP implementation.

Recent versions of the BSD ftp and ftpd support a restart option,
which can be accessed using the "restart" and "reget" commands to the
FTP client; if your FTP client supports these commands, and the server
does as well, you're in business.

This code comes from Berkeley, and is in at least 386BSD and HPUX
8.07; I'm not sure when it was introduced.

Check your vendor and/or on-line documentation; if the support isn't
available, you may also be able to pick up the sources to the berkeley
FTP by anonymous FTP and port and build them yourself..

This is being investigated off-line, but I thought I'd post an initial
response for everyone else.

To my knowlege, we do not allocate GAA devices. We're running VMS versions
ranging from V5.1 through V5.5 with DECwindows or Motif and there should
be no conflicts.

	What are the other paramaters in the SOA?
	Which zone?
	2 days seems a very short expire interval.
	Normally Retry << Refresh << Expire (e.g. 300 << 3600 << 3600000)
	and Refresh <= Minimum.
	If your Refresh > Expire I would expect this sought of behaviour.

There are really two issues to consider when setting up the firewall to
permit DNS queries (or any other communication for that matter):

   1. Requests initiated *outside* the firewall:
      Permit incoming request to *known* privileged port number(s)
      and outgoing replies to *unknown* non-privileged port numbers
   
   2. Requests initiated *inside* the firewall:
      Permit outgoing requests to *known* privileged port number(s)
      and incoming replies to *unknown* non-privileged port numbers

Half of the solution to these issues has been pointed out by many people:
The known port number for DNS queries/transfers is 53 for both tcp and udp
protocols.
Thus incoming/outgoing packets must be allowed for protocols tcp and udp
for port number 53 .

The other half of the solution I had to figure out for myself:
When contacting DNS (and many other services) the request is sent to a
*known* privileged port (53), but the reply is sent to a random
non-privileged port (>1023) specified by the requester.
Thus incoming/outgoing packets must be allowed for protocols tcp and udp
for all port numbers >1023 .

This solution has been tested and works fine.

Thanks to all that responded !

My PC-based DNS resolver implements a local name cache which it uses

Terry,

	Let me add my two deficiences:

1) DNS should support other address classes besides InterNet (IN), including
(but not limited to) Apple Talk (AT?),  DECnet (DN?), OSI or DECnet phase V
(OS?), etc.

2) This is probably an implementation issue, but the resolv.conf and named.boot
files should be able to use names instead of IP addresses, and use /etc/hosts
to look up the addresses.

I have encountered this problem previously. The problem is a misconfigured

the secondary server.
