• Installation of a new machine

1. set a superuser password
2. disable all shipped accounts (lp, guest, etc)
3. enter machine name in /etc/sys_id
4. enter machine name and ip number in /etc/hosts
5. create /etc/resolv.conf

• domain bmsc.washington.edu
• nameserver 128.95.235.21
• hostresorder local bind
6. create /etc/config/ifconfig-1.options

• netmask 0xffffff00
• broadcast 128.95.235.255
7. check the network connection with the ping command
8. install dials
9. load NFS, C, FORTRAN (Varsity disk) and BSDLPR (OS disk)
   look for: compiler_dev, ftn_dev, c_dev, dev.hdr, dev.hdr.lib, nfs
10. ftp the /etc/printcap file from another SGI and create the necessary directories in the /usr/spool directory
11. add local hosts to /etc/hosts (necessary for export command)
12. create /etc/exports
13. increase swap space (use tools under sysadm)
14. reboot: NFS should now work
• When the network is down

1. call campus network folks at 3-5128
• When print queues are stalled ...

1. cd /usr/spool
   
2. ls *
   the stalled jobs are visible in directories lpd, lpd1, lpd2, etc.
3. /etc/init.d/bsdlpr stop
4. /etc/init.d/bsdlpr start
• When the objectserver is not responding

1. /etc/init.d/cadmin stop
2. /etc/init.d/cadmin clean
3. /etc/init.d/cadmin start
• Replacing a system disk

1. print the current diskheader info: prtvtoc
2. make a system backup: use Backup & Restore from the Desk toolchest
3. for backup on a remote drive: enable the guest account on the remote machine
4. check the system backup: bru -t
5. replace the disk
6. use the recover option of the maintenance menu and follow the instructions

• make a filesystem: you might like to use the prtvtoc info you printed before
• if you use a remote drive to load the backup: enable tftp as follows
• in /etc/inetd.conf: remove "-s /usr/local/boot ..." from the tftpd entry
• read the system backup (if remote, use /dev/tape as driver)
7. reboot
8. restore the original tftp line in /etc/inetd.conf
9. disable the guest account
