Re: Fun with NDMP - toasters

9 Apr 1998


      Hi Tripp,
...
I have successfully (I think) ported ndmpcopy to Digital Unix,
Cool! Any chance you can contribute your changes back to
    ftp.ndmp.org. If you leave the code in /incoming. I'll
    make sure it makes its way to the contrib directory.
...
but I am running into some problems trying to initiate a copy.
Boo. Hiss.
...
adminhost# ./ndmpcopy srcfiler:/ms/ftp destfiler:/ftp -sa 
root:passwd -da root:passwd -level 0 -v
srcfiler> Thu Apr  9 17:09:12 EDT [ndmp_session_0]: 
../common/ndmpd/mover.c:1169 ndmpdMoverConnect: connect error: 
No route to host
destfiler> Thu Apr  9 21:09:12 GMT [ndmp_session_0]:
../common/ndmpd/mover.c:1169 ndmpdMoverConnect: connect error: 
Can't assign requested address
I can ping destfiler from srcfiler and vice-versa.
The output below shows me that the mover on the destination
    is still listening for a NDMP data connection to be initiated
    by the source machine. Obviously the DEC client can see both
    filers, but perhaps the filers can't see each other on these
    addresses without a route being added. You can check that all
    ip addresses are consistent on each machine. I know that I will
    change the local hosts file on a filer here to talk to a server
    that the filer knows as server1 (111.222.333.12) whereas the yp
    map on all other clients will be server1 (222.333.111.70) and
    server1-333 (111.222.333.12).
Alternatively, you could use the -dhost option with NDMPcopy
    and provide the ip address of the destination filer. You get
    this value from running ping -s destfiler from srcfiler.
BTW, you can generate a bunch of (pretty cryptic) debug by
    running:
rc_toggle_basic ; dbg level ndmpd=0xffff ; rc_toggle_basic.
To turn off again run:
rc_toggle_basic ; dbg level ndmpd=0x0 ; rc_toggle_basic
Hope this helps. Let me know how you get on or if you have
    any more questions.

Here's some interesting information:
