|
<P><STRONG>Description</STRONG>
|
||
|
|
<P>The client version of the <B>ThisCell</B> file defines the complete
|
||
|
|
Internet domain-style name (for example, <B>abc.com</B>) of the
|
||
|
|
cell to which the local client machine belongs. It must reside in the
|
||
|
|
<B>/usr/vice/etc</B> directory on every AFS client machine. To
|
||
|
|
change a client machine's cell membership, edit the file and reboot the
|
||
|
|
machine.
|
||
|
|
<P>The file is in ASCII format and contains a character string on a single
|
||
|
|
line. The <I>IBM AFS Quick Beginnings</I> instructs the
|
||
|
|
administrator to create it during the installation of each client
|
||
|
|
machine.
|
||
|
|
<P>The client machine's cell membership determines three defaults
|
||
|
|
important to its functioning:
|
||
|
|
<UL>
|
||
|
|
<P><LI>The cell in which the machine's users authenticate by default.
|
||
|
|
The effect is two-fold:
|
||
|
|
<UL>
|
||
|
|
<P><LI>The AFS-modified login utilities and the <B>klog</B> command
|
||
|
|
interpreter contact an Authentication Server in the cell named in the
|
||
|
|
<B>ThisCell</B> file (unless <B>-cell</B> argument to the
|
||
|
|
<B>klog</B> command specifies an alternate cell).
|
||
|
|
<P><LI>The command interpreters combine the cell name with the password that the
|
||
|
|
user provides, generating an encryption key from the combination. For
|
||
|
|
authentication to succeed, both the cell name and password must match the ones
|
||
|
|
used to generate the user's encryption key stored in the Authentication
|
||
|
|
Database.
|
||
|
|
</UL>
|
||
|
|
<P><LI>The cell the Cache Manager considers its local, or home, cell. By
|
||
|
|
default, the Cache Manager allows programs that reside in its home cell to run
|
||
|
|
with setuid permission, but not programs from foreign cells. For more
|
||
|
|
details, see the <B>fs getcellstatus</B> and <B>fs setcell</B>
|
||
|
|
reference pages.
|
||
|
|
<P><LI>Which AFS server processes the local AFS command interpreters contact by
|
||
|
|
default as they execute commands issued on the machine.
|
||
|
|
</UL>
|
||
|
|
<P>The client version of the <B>ThisCell</B> file is distinct from the
|
||
|
|
server version, which resides in the <B>/usr/afs/etc</B> directory on each
|
||
|
|
AFS server machine. If a server machine also runs as a client, it is
|
||
|
|
acceptable for the server and client versions of the file on the same machine
|
||
|
|
to name different cells. However, the behavior that results from this
|
||
|
|
configuration can be more confusing than useful.
