5564.0. "BIND/DNS strange behaviour" by BACHUS::ROELANDTS (Wa d'es ma da ve ne stuut) Wed Jun 04 1997 09:31

    Hello,

    Does anyone know what could cause the following problem ?

    Thank you for any info.

      Regards,

           Guy

    We have, here at our TSC, 4 Bind servers :

    1. Primary server    : ns1.bro.dec.com    - DU V3.0 

    2. Secondary servers : ns2.bro.dec.com    - Ultrix V4.2A
                           dbc331.bro.dec.com - VAX VMS 7.0 - UCX V 4.1-PAT8
                           duma.bro.dec.com   - Windows NT V4.0 SP3

    When, from an UCX system, we try to resolve names everything works fine,
    whatever the DNS server we use :

  $mc ucx$nslookup
  Default Server:  ns1.bro.dec.com
  Address:  16.183.0.2

  >brssws
  Server:  ns1.bro.dec.com
  Address:  16.183.0.2

  Name:    brssws.bro.dec.com
  Address:  16.201.0.38


  >server ns2
  Default Server:  ds5100.bro.dec.com
  Address:  16.183.0.200
  Aliases:  ns2.bro.dec.com

  >brssws
  Server: ds5100.bro.dec.com
  Address:  16.183.0.200
  Aliases:  ns2.bro.dec.com

  Name:    brssws.bro.dec.com
  Address:  16.201.0.38

  >server duma
  Default Server:  duma.bro.dec.com
  Address:  16.201.0.151

  >brssws
  Server: duma.bro.dec.com
  Address:  16.201.0.151

  Name:    brssws.bro.dec.com
  Address:  16.201.0.38

  > server dbc331
  Default Server:  dbc331.bro.dec.com
  Address:  16.201.0.170

  > brssws
  Server:  dbc331.bro.dec.com
  Address:  16.201.0.170

  Name:    brssws.bro.dec.com
  Address:  16.201.0.38

  But when using the UCX interface to resolve names things get more complicated

  UCX> sho host/nolocal/server=ns1 (or server=duma)  returns :

  %UCX-W-BIND_NOSERVNAM, Server with address 16.183.0.2 is not responding
  %UCX-E-BIND_NOSERVERS, Default servers are not available
  %UCX-W-NORECORD, Information not found
  -UCX-E-BIND_NOSERVERS, Default servers are not available

  The trace appended at the end of the note shows the same operation

  UCX> sho host/nolocal/server=ns2 (or server=dbc331) works fine

  
     BIND database

  Server:   16.183.0.200     DS5100

  Host address    Host name

  16.201.32.200   bro.dec.com
  16.1.224.2      lion.pa.dec.com
  16.1.224.2      lion.pa.dec.com
  16.1.224.2      lion.pa.dec.com
  16.1.224.2      lion.pa.dec.com
  16.1.224.2      lion.pa.dec.com
