I administer 9 workstations with about 100 users. Each user has an account on one machine and the other machines are nfs mounted. I would like to use automount but I have not been able to figure out how. If anyone in a similar situation has experience with automount I would appreciate the help. Note: I am waiting for the hotline to call me back (1 day and holding) but the net provides another source of information. N.B. This is NOT hotline bashing, I'm just looking for the most information. -- *-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-* \ / \ / \ / \ / \ / \ / Jeff Hanson \ / \ / \ / \ / \ / \ / * ViSC: Better * tohanson@gonzo.lerc.nasa.gov * * * * * * / \ / \ Science / \ / \ NASA Lewis Research Center / \ / \ Through / \ / \ * * * * * * * Cleveland, Ohio 44135 * * * Pictures * * \ / \ / \ / \ Telephone - (216) 433-2284 Fax - (216) 433-2182 \ / \ / \ / *-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*

I am personally responsible for only five machines, however, we are part of a very large network of iri and sparcs. This is the way I have it set up. I have set up the "real" home directories to be /usr/<machine>/<user> on those machines that have home directories (two of the five). Other administrators for the iri around here have done the same thing. The sparcs already have the homes under /home. I made /home the toplevel indirect mount point for the home directories on our iri. The passwd entries for home areas look like /home/<machine>/<user>. I'm not sure about "automount" but "amd" can be set up with conditionals. So lets say my "real" home is in /usr/A/srp, my passwd entry is /home/A/srp If I logon to host "B", "amd" mounts the /usr/A partition in a work area, and makes a link from /home/A to /usr/A if I logon to host "A", "amd" realizes that it is the localhost, and simply makes a link from /home/A to /usr/A (no mounts needed). On each class of machine around here each person has only one home. So in the future I will probably "generalize" this to /home/iris/<user> /home/sun/<user> /home/mips/<user> ...you get the idea. though another layer of links in the maps, rather than being dependent on the hostname in the path. There *are* some gotchas... For instance, if you use the iconic login facility, each time you logout, pandora looks to everyone's home directory for an icon to display (even if you specify in the /etc/passwd.sgi file that these people will not have an icon displayed - I put in a SCR on that) ... can you say "mount storm" ? Also the pwd display in your prompt will be ugly. Its hard to talk about without showing you the map file. I can send you example map files.

N.B. This is NOT >hotline bashing, I'm just looking for the most information. >-- Here's one quick, easy, and useful way of configuring the automounter. I use this here interally at SGI... with wonderful success I may add (I have no NFS entries in my /etc/fstab, for example!). This all, by the way, is described somewhere deep in the automount man page. (I know, it took me a while to glean out this simple tidbit). NOTE: This assumes you use YP for host name<->IP mapping. (on each client machine) # echo /net -hosts > /etc/config/automount.options # chkconfig automount on # /etc/reboot or # automount `cat /etc/config/automount.options` YAY! You're now all set. On this machine you may now do ``cd /net/<hostname>/<exported-dir>'' (nothing magic about "cd" -- _any_ use of this pathname will do the trick) and the automounter will automagically NFS mount all exported directories on host <hostname> at /net/<hostname> on your machine. If <hostname> is the local host automount still builds the symlink in /net/<hostname>. This permits network-transparent absolute symbolic links. Automount is great! No mkdir'ing of mount points. No /etc/fstab entries to maintain on N machines. enjoy! Bent
