Dear All,

Begging your pardon for my questions, not being familiar with
AFS but must migrate this server.

Abandoning the idea of trying to mirror the IBM AFS3.5 Win2K
server onto a SL4.5 server, now to start experimenting with
setup test AFS cell, to get a feel for how it works.

For making a new cell/server IBM AFS doc instructs to start
'kaserver' which I get the impression is now verboten? =20
Is that the only part of the IBM AFS doc that
is to be ignored? Or most/all?

Can the KeyFile copied from the orig Win2K AFS server
be used on an different afs-realm SL4.5 test box?

If not, our microsoft KDC admin will have to to do something
on the KDC for a different AFS cell - correct?
That's the kind of PITA it was hoped to avoid by mirroring an
existing AFS server & not making a new cell.

Assuming the same KeyFile can be used,

root@vlad> bos setcellname localhost test.phy -noauth
root@vlad> bos listhosts localhost -noauth
Cell name is test.phy
    Host 1 is <name of our REAL afs-cell server>

Why is it listing the afs server in our official AFS cell?
It has nothing to do with cell test.phy!
Is it because of the copy of KeyFile from the other machine?

root@vlad> bos listkeys localhost -cell test.phy -noauth
key 0 has cksum 656054385
Keys last changed on Tue Feb 18 20:32:21 2003. [ yep, that's the old key ]
All done.

root@vlad> bos create -server localhost -instance ptserver -type simple \
-cmd /usr/afs/bin/ptserver -cell test.phy  -noauth

No go - BosLog says "ptserver exited with code 2" &
googling for that =3D null useful
PtLog has :
Sat Aug 30 17:16:24 2008 Inconsistent Cell Info on server: Sat Aug 30
17:16:24 2008 <test-server-IP> Sat Aug 30 17:16:24 2008
ptserver: problems with host name Ubik init failed

What does "problems with host name Ubik init failed" indicate?
Googling is no help, the only very old mentions of this indicated
"problem is hostname resolves to" - not true on
this test server.

Very grateful for lucid guidance.

No errors in FileLog though - progress!
