I'm sure the solution to the following problem is *really* simple, but for the life of me, I just can't find it! Configuration: SunOS 4.0.3. Sun 4/370 -> exporting home directories and binaries for diskless clients SS1 -> dataless client. (has root and swap on internal drives) 4/370 /etc/exports: /home /export/exec/sun4c -ro /export/exec/kvm/sun4c -ro SS1 /etc/fstab: /dev/sd0a / 4.2 rw,nosuid 1 1 /dev/sd0e /var 4.2 rw 1 4 370host:/export/exec/sun4c /usr nfs rw,bg 0 0 370host:/home /home nfs rw,bg 0 0 Problem: The commands, w, vmstat, and ps (!) do not work on the dataless client, but do so on the 4/370. "w" and "ps aux" simply return silently while vmstat comes back with the message "vmstat: Disk init info not in namelist". As the only common thread between the above commands seems to be /dev/kmem, I checked the permissions and they are identical on both machines: crw-r----- 1 root 3, 1 Jun 11 20:28 /dev/kmem When the SS1 was set up as a standalone machine, everything works as it should. So, it would appear to be related to the dataless configuration. I know that the problem was recently created because these commands used to work. Please tell us the solution and we promise not to break our machines again ;-). Thanks kindly, Robert Lee Internet: rlee@digital.co.jp

That would cause 'w' and 'ps' to stop working, because they need the symbol table in /vmunix to find addresses in /dev/kmem. That's probably the problem with 'vmstat' too, since complains about a 'namelist' (/vmunix). Dean Long dlong@soledad
