I think the parser is a little bit picky and thinks that your lines should
start with directly with the ip-address.

Can you try the patch below and see it that helps you ?

klog uses /etc/krb.conf (since it's using a krb4 lib). Put this in your
/etc/krb.conf file:

----8<---- 
ISIS.UNC.EDU
ISIS.UNC.EDU db0.isis.unc.edu adminserver
ISIS.UNC.EDU db1.isis.unc.edu adminserver
ISIS.UNC.EDU db1.isis.unc.edu adminserver
----8<----

--debug=almost-all is a good one to arlad, or you can use `fs arladebug' or
`fs xfsdebug' to change then will running.

Well, that might not be so good. The problem is that we want to tell the
user where the files are installed. But since it can change and we don't
generate files when we install, it easy to get confused.

It will look in sysconfdir, and that is in your case /etc/arla.
