Misc Notes

Enabling NFS on Sun Solaris 2.5.1

Need to edit the file /etc/dfs/dfstab with the share command to make the thing shared:

share -F nfs -o ro -d "The CDROM" /cdrom/cdrom0

Start the NFS daemons /etc/init.d/nfs.server — server won't start if /etc/dfs/dfstab is empty.

Add entries to /.rhosts to allow remote users to mount systems.

Changing the IP Address on CiscoWorks

Change the IP address in /etc/hosts. Sybase locks the IP address — edit $SYBASE/interfaces to the new IP address.

Unix Stuff

psrinfo -v displays processor speed under Solaris.

When adding a new SCSI device to a Solaris host, halt the host and get to the boot prompt and issue the command boot -r to get the host to run mknod for each new SCSI node.
