Hmmmm,  I'm looking at the AT&T PRI spec (TR 41449/TR 41459) and the only
Information Elements that are mandatory are:

	Bearer Capability
	Channel Identification
	Called party number

Experience tells me that the Bearer Capability for an incoming call often
bears no relation to the one in the originators setup message.

The channel ID IE is node-to-node, not end-to-end.  All its bits are accounted
for anyway.

The "mandatory" called party number isn't in setups that come from a Definity
Generic I PBX.

Ok, on to BRI and the 5ESS specifically (I'm not picking on AT&T, it's just
that I happen to have their manuals at home).  Only the Bearer capability is
required.

Maybe in the future when the world is SS7 you'll be able to trust the bearer
cap IE.  Until that time
* as your call goes from switch to switch it can (and will) be munged
* it sometimes lies.  I've received calls with a 64K Bearer Cap IE that I
  *know* went over at least one line/network that only had 56K capabilities.

Now where is that bit?

I have installed the Intel slip driver on a Consensys Unix System V rel 4.0.3.
When using a dialup a slip session can be started and finished ok.
When someone tries subsequently to login the /etc/issue message is displayed
without carrage returns. Any character typed in at the login prompt clears the
call. The slip driver pops the ldterm and ttcompat modules before attaching.
It looks as though the modules are not being pushed by ttymon before restarting the service.

I would be grateful for any help.
Has anyone ported dialupip for SysV?

I just ran into this problem with a VAX running VMS and WIN/TCP.  A PC/IP-
derived FTP couldn't fetch from it, because the VAX wasn't defaulting to a
536-byte maximum segment size (MSS) as it should have.  When I modified the
PC TCP to send the TCP MSS option with an MSS of 536, the VAX *still* sent
1500-byte packets.

One solution is to reduce the MTU on the Tandem to something smaller, if
possible.  This will reduce throughput when talking to machines capable of
the maximum MTU, but will provide compatibility with the Mac.

The solution to our problem, though, was to upgrade WIN/TCP to its current
release.  :-)

 I have a question here about DNS implementation. Any thoughts would be
 appreciated.

     If we have primary and secondary servers on our domain, the primary
     nameserver would reload if it receives a SIGHUP. Furthermore, if an
     intentional error is introduced in a RR record in the primary's database,
     the secondary nameserver does not get reloaded. Should IT?

Hi,

I am having problems with the primary name server
here that has some IP address which wouldn't die.

when i do an nslookup

> solomon.technet.sg
Server:  localhost
Address:  127.0.0.1

Name:    solomon.technet.sg
Addresses:  192.169.33.3, 137.132.3.3, 192.169.33.1, 192.169.34.1


192.169.33.1 and 192.169.34.1 are very old
address on solomon which have been assigned somewhere else
already. 

On the name server directory on NUSCC.NUS.SG, the data base
file "sg.db" does not contain this records at all!!

The only address that i wish the name server to advertise
is 192.169.33.3, and forget the rest.

I have changed the serial number on the file sg.db which is

"nuscc.nus.sg"
primary  sg   sg.db

and on my solomon, which is secondary for sg,

"solomon.technet.sg"
secondary sg nuscc.nus.sg  sg.da

I get a copy of sg.da that is different from sg.db

which include the ghost address, and a ttl for 137.132.3.3
which is not specified at all in sg.db

I am planning to move the primary for sg to solomon.technet.sg
and i need to overlap it temprorary, but before i do that i
wish that at least it could stop propagating the ghost
address 192.169.33.1, 192.169.34.1, and also the 
137.132.3.3 address as it will be removed later.

Any body has any idea what went wrong?

Your delegation of ncm.interlan.com is fine (although I'd get a secondary 
nameserver running real soon now...)

Since address-to-name queries are looked up a different DNS zone 
(204.130.in-addr.arpa), these queries are not "automatically" forwarded
to your new nameserver.  Such queries will be answered by a current
nameserver for 204.130.in-addr.arpa whose primary DNS server is interlan.com.
If you insert the appropriate PTR record on that system, the address-to-name 
lookup should work fine.

What?  You want to delegate administration of those PTR records as well?
This may be possible, depending on your circumstances.  DNS allows delegation
of authority on "." boundaries.  For example, it is technically simple to
have the authority for 35.204.130 delegated to ncm, and configure ncm for that
zone with PTR records.  Whether or not this is feasible depends on the 
administration of the 204.130.in-addr.arpa domain and the probability of
a host "outside" of your authority ending up with a 130.204.35.xx address.

That's a real brief overview.  Post any unanswered questions, or contact 
your network service provider for specifics.

Question:

If the nameserver were to receive a SIGHUP, it would reload the database for
itself as well as for any secondaries through a zone file transfer. If for
argument sakes, an invalid record was encountered ( any incorrect RR ) during
the reload, that RR is skipped by the primary and the rest of the records will
be loaded. My question is, how should the secondary be updated? Should it'
database be refreshed also by the primary by a zone file transfer or not. Shouldit not also be refreshed and have the ame contents as the primary's database.
I need suggestions for implementation:

Hi there!

Well, it is time for our network to migrate to Domain Name services.
Here is a summary of my situation:

We were using our standard Internet Address for our token-ring lan and 
the default 192.9.200 for our ethernet lan.

So far no problem but.... because we are incorporating to the INTERNET
we will be making changes to our addresses.
What i have done so far is test the subnet issue.
We have defined our choices there: we will be using the 3 highest bits
(netmask 224) and do with 6 subnets.

Here comes the question>

Has anyone implemented this setup with NIS with DNS (named).
The docs say that NIS can run with domain name services on top of it
I am reading chapter 17 of the SUN : System & Network Administration in
order to understand what is going on but I must confess that I am still
not sure how to go about it.
Based on the samples I have created the boot files for my 3 servers
but like i said, is not complete.

Can any one share some hints, 
I have a combination of token-ring and ethernet unix hosts and PC's.
I want to use subnets for security reasons (the machine that will connect 
us to the internet via a router will be in one subnet along with the
router).

Ideally, I would like to use NIS to handle local addresses and DNS when 
needing info about INTERNET addresses.
My HUB supplier (Cerfnet) has already given me the name of the domain name
server that I should use to link to the INTERNET.

Thanks in advance, in the menatime I will keep on reading.

 1) modify SOA value in primary name server's zone file
 2) restart primary name server
 3) modify SOA value in secondary name server's zone file
    to a lower value than in 1), or simply remove that file
 4) restart secondary name server

I've just tried to resolve asu.edu :

Using domain server:
Name: ASUVAX.EAS.ASU.EDU
Address: 129.219.30.5
Aliases:

asu.edu NS ASUVAX.EAS.ASU.EDU
asu.edu NS CCNUCB.COLORADO.EDU

As you could see, the A recourd isn't there.

You don't need a A record to do what you want, you only need a MX record.
An A record could be an last resort for those Mail systems, which could not
use MX-records, but is not needed.
