[OpenAFS] How to replicate files on different
Tue, 19 Dec 2006 17:12:43 +0530 (IST)
I'm trying to use 'kinit' and 'aklog' to get admin tokens for accessing the cell under /afs on my client machine.
Though these are installed on my machine, I'm not able to configure these, since I'm not able to find the syntax for using 'aklog' in 1.4.2 documentation.
As we use 'kas' tool to create Authentication Database entries, which are later accessed by 'klog' command, is there any similar way to create entries for 'aklog' and 'kinit'?
Write now the output of these commands is as follows.
aklog: Couldn't get ps1.pspl.co.in AFS tickets:
aklog: No credentials cache found while getting AFS tickets
kinit(v5): Cannot resolve network address for KDC in requested realm while getting initial credentials

Replication applies to whole volumes, not individual files, and requires an
explicit "release" operation to cause changes to the read/write volume to
be propagated to the read-only replicas. AFS does not provide replication
of read/write data.

That is what the output from recent versions of 'ls' looks like when you
don't have permission to access the file in question. Most likely that is
indeed a directory (actually, an AFS mount point), but since you have just
set up a new cell, its contents are visible only to AFS administrators, and
you don't have AFS admin tokens. You will need to acquire tokens using
tools like 'kinit' and 'aklog' before you can access that directory.
