Novice question !!! Please teach me how to have a node-specific file on a diskless Sun ? I am porting a software product from HP to Sun. HP has a "cluster" to support diskless nodes. They have Context Dependent File (CDF) to have a node-specific file for each node. How does Sun support such an idea ? It seems to me that Sun makes heavy use of NFS and symbolic links. What man pages do I need to read ? Thanks in advance, Masa

If you're asking what I think you're asking, the answer is to put it in /etc, /tmp or /var/tmp. Each of these directories are host-specific. (The rest of this discussion assumes that an HP "node" = a Sun "host".) When a diskless Sun workstation boots up, it has two "partitions" at its disposal: the root partition and the swap partition. Since the /etc directory is on the root partition, and each workstation has a different root partition, files such as /etc/hostname.ie0 are specific to the "node". For example, these files exist on the file server: /export/root/alpha root partition for workstation alpha /export/root/alpha/etc/hostname.ie0 has alpha's host name /export/swap/alpha NFS file use for alpha's swap space /export/{root,swap}/beta files for workstation beta /export/root/beta/etc/hostname.ie0 has beta's host name /export/exec/sun3/sunos.4.1.1 /usr for Sun3 (Motrola 680x0) CPU's /export/exec/sun4/sunos.4.1.1 /usr for Sun4 (SPARC chip) CPU's /export/share/sunos.4.1.1 man pages, termcap, fonts, etc /home/servername user's personal directories The diskless workstation, however, sees only: / root partition for this workstation (swap) swap partition for this workstation /usr /usr for this type of workstation /usr/share common stuff for all workstations /home/servername user's personal directories >It seems to me that Sun makes heavy use of NFS and symbolic links. >What man pages do I need to read ? Note: Symbolic links are not necessary, it's all done with NFS mounts. The above information is from experience with installing diskless workstations. I looked in Sun's manuals, but could not find any place where this information is presented. -Joe -- Joe Smith (408)922-6220 | SMTP: jms@tardis.tymnet.com or jms@gemini.tymnet.com BT Tymnet Tech Services | UUCP: ...!{ames,pyramid}!oliveb!tymix!tardis!jms PO Box 49019, MS-C51 | BIX: smithjoe | CA license plate: "POPJ P," (PDP-10) San Jose, CA 95161-9019 | humorous disclaimer: "My Amiga 3000 speaks for me."
