2131.0. "DAP error during a copy OSF/RSX11M" by MLNCSC::DOMANESCHI () Mon Feb 17 1997 11:21

	Hi all,

   my customer has signaled to me a problem between a DECnet/OSI for OSF 3.0
   and DECnet/RSX11M 4.2 during a copy.

   from osf:

   dcp rsxname/user/pass/::file_name /usr/users/xxxx

   Dcp error reading du0:[1,1]file.cmd bad format dap message received
   invalid message,control message error,block count field (blkcnt)

   from pdp11 the problem is the same.
   The customer has problem only with dcp a dls and drm work fine.
   Any idea?
   Thanks in advance.

   I posted also on DECnet/OSI OSF conference

    Well, first off, 3.0 is no longer suppported.
    
    Second, the error message is bizarre - dcp usually SENDs
    control messages, it doesn't RECEIVE them.
    
    Because I'm curious, if you get a trace (use the -d switch
    to dcp), I'll take a look.  But even if its a problem on
    the UNIX side, we're not going to do a 3.0 fix.

    Things become a bit clearer.  The RSX system doesn't like
    the block count field OSF sends in its control message.
    
    We send a value of 2, which is quite normal, and should fit
    in the negotiated buffer size (2*512 + few-bytes-overhead) <
    1062 (the buffer size RSX gave us).
    
    Has anything changed on the RSX system?  What happens if you 
    try image mode (dcp -i) ?

	Vince,

     with a dcp -i the problem is the same, apparently nothing is changed 
     on RSX11 system, it is an old installation
     In his lan he has a VAX with OpenVms 5.5-2 and DECnet phase iv 
     the copy works fine from PDP to VAX and UNIX to VAX and vice-versa.
     Now the customer is investigating on RSX11 and testing from an Alpha 
     with 3.2c.
     
     I'll post here the news.
     Bye.
