SUMMARY: Problem with changing a master server

Hi all,

got one response so far (from ed.rolison@itc.alstom.com, thanks Ed!), and
this one solved the problem. I attach Ed's response to this summary, seems
things are much more easier as my NIS-Book says, :-)
Btw., Ed: The /etc/hosts is not the problem, the new server had an entry
there - I think something's going wrong during the rpc call, maybe due to
caches or things like that.
But, as I said: It's much more easier to do it the way Ed described, without
all that ypxfr-work...

Here's Ed's reply:

kind regards, and thanks for help,

Betreff: NIS: Problem with changing a master server


Hi Gurus,

I've a problem with changing a NIS master server. My NIS Admin Guide (O'
Reilly, "Managing NFS and NIS") says I should setup the new master a
NIS-slave, rebuild the NIS-maps on the new master with NOPUSH=1, and then
transfer the newly generated NIS-maps to the old server using ypxfr:

ypxfr -h newmaster -f <NIS-map>.

I've setup the slave, rebuild the maps, but when I try the ypxfr, I get the
following error message:

ypxfr: couldnot get <newmaster> address
(info) <newmaster> passwd.byuid ypxfrd getdbm failed (reason = -1) -- using
ypxfr

What does this mean?
The address of the new master is present in the old master's /etc/hosts, so
I thought it should work. I also added the new master's hostname to the
ypservers-map and rebuild the ypservers map using makedbm...
Where's the problem?
Anyone seen this before?

Thanks for your help, will summarize.

kind regards,

Harald
