TAPE BACKUP STRATEGY
IF YOU NEED TO PUT IN A SINGLE TAPE (eg for a restore)
  1. Log onto backup as root and run nvgui. Click on Device Managment.
  2. RT-click Drive-1 and select unload to unload any cartridge currently in the drive.
  3. RT-click backup0-0.1.0(STK L20) and select open entry/exit
  4. When msg tells you port is open, open the flip-down drawer on the LHS of the L20 and put in the required cartridge.  Label goes to the left, hib side of tape goes towards the inside.  Close the entry/exit door.
  5. RT-click backup0-0.1.0(STK L20) and select close entry/exit
  6. If a restore job is waitng for that tape cartridge, it will automatically be loaded and will get read.
  7. After you are done with the tape, you need to RT-click on the drive/tape and select export

TO CHANGE MULTIPLE TAPES (or just to open drawer)
  1. Log onto backup as root and run nvgui. Click on Device Managment.
  2. RT-click [Drive-1] and select [Unload] to unload any cartridge currently in the drive.
  3. RT-click on [backup: 0-0.1.0 (STK L20)] and select [Open Door].
  4. Complete operation by interacting with LCD and buttons on front panel of tape drive.
    On L20 front LCD panel, Press [MENU]
    • "DRAWER OPERATIONS" should be selected.  If not, use up/down buttons until "DRAWER OPERATIONS" is shown.
    • Press [Select];  message = "Press Select to prep lib for opening drawer"
    • Press [Select];  message = "Are you sure?  Lib will be offline"
    • Press [Select];  message = "OK to open drawer"
  5. Use key attached to drawer to open it.  Press firmly then turn CCW - drawer is spring-loaded and should pop open.
  6. Pull drawer completely open and change tapes as required.
  7. Close drawer by pushing in, pressing key firmly in and turning it CW to secure drawer in closed position.
  8. After a few minutes, you will get the message: 
       STK L20 - Ready
       CAP Busy
       OO empty
  9. RT-click on [backup: 0-0.1.0 (STK L20)] and select [Door Closed].

WEEKLY BACKUP TAPE CHECK
  1. At the end of every week (Thursday or Friday) the tapes should be checked and any full or near full (>80% used) tapes should be replaced.
      There is a sheet (near keyboard?) for recording which tapes have been changed each week.
  2. Log onto backup as root and run nvgui. Click on Device Managment.
  3. RT-click each slot and select [Status] to see percent usage.
  4. If (almost) full, mark it as needing changing on the sheet and record the date last written. This information is found under the [Statistics Tab] on the Status screen.
  5. NOTE: We store the tapes on the shelf behind you in order last written - oldest first, so that they are re-used in this order.
  6. Once you know how many tapes need to be changed, you can take that many tapes from the left-side of the first shelf behind, keeping them in order.
  7. Open the tape drive as per the instructions above.
  8. Replace the tapes in the correct order and put the removed ones on the shelf at the right-end of the row.
  9. Close the tape drive as per the instructions above.
  10. Record the new tape numbers on the sheet for next week.
  11. Just in case, RT-click each slot with a new tape in it and select [Re-use].

MONTHLY BACKUP TAPES
  1. Slots 7 to 9 are for the monthly backup tapes. They should be checked and changed as per the weekly instructions above.
  2. Replace the monthly backup tapes using the oldest available daily backup tapes. Then replace the daily tapes with brand new tapes.
  3. After inserting a replacement tape into one of the monthly slots, RT-click the slot and select [Properties] to change the Group Label to "Monthly".
  4. The removed monthly tapes should be stored in the boxes that are labelled appropriately.
  5. New tapes are generally located on the shelf next to the Monthly tapes.

DATABASE BACKUP TAPES (NV-DBASE-nnn)
  1. The Ultrium-215 drive contains the tape for storing the Netvault database. It should be checked and changed periodically (weekly?).
  2. To change the tape: RT-click on [Ultrium-215 - NV-DBASE-nnn <Nv-DBase>] and select Unload.
  3. When the tape is spat out, replace it with one of the NV-DBASE tapes - located on the 2nd shelf behind.
  4. Use the same procedure as for the regular backup tapes - ie. take from left, add to right.
  5. Insert the replacement tape in the Ultrium-215 and RT-click to select Load.

NOTE:  You don't need to label blank tapes.  I have set up the software to automatically label tapes as required.

This confirms that the drive is configuree properly and is running the fastest it can.

03-06-24
- Info from HP engineer: Want to use a separate SCSI controller for the Ultrium.   Try to put the controllers on separate PCI buses.  Try to use 64-bit 3.3 volt bus (not 5 volt or rate will be limited).  In software, set buffers and block-sizes to 64Kb.  Put the LTO as last on the SCSI chain.
02-06-05
- RedHat 8.0is installed.
- Updated giptables to allow snmp traffic.
- Bakbone NetVault is installed to do backups.  Currently alpha &  warp (physics) are being backed up.

- partitioned as follows:

<swap> /dev/sda2 xM Linux swap

/home /dev/hda1 37G ext3


2001-05-01 Tripwire setup:
  1. Run the configuration script /etc/tripwire/twinstall.shto sign these files. This script walks you through the processes of setting passphrases and signing the Tripwire policy and configuration files.  Please Note: Once encoded and signed, the configuration file should not be renamed or moved.
  2. Initialize the Tripwire database file. ( /usr/sbin/tripwire --init )
  3. Run the first integrity check. ( /usr/sbin/tripwire --check, or /usr/sbin/tripwire --check --interactive, or /usr/sbin/tripwire --check --email-report ).  If you have used the non-interactive mode, you need to update the Tripwire database after an integrity check,

  4. /usr/sbin/tripwire --update -r /path/report-xxx-yyy.twr
    see page 215 of Securing and optimizing Linux or RHL-7.1-Manual
  5. Edit the configuration file (twcfg.txt) with a text editor, if desired.
  • Edit the policy file (twpol.txt) with a text editor, if desired.

  • Please Note
    If you plan to modify the policy file, we recommend you do so before running the configuration script. If you modify the policy file after running the configuration script, you must re-run the configuration file before initializing the database file.

    Depends on what you mean by "secure."  Do you mean relatively unspoofable and uncrackable, or do you mean "cryptographically secure?"

    If the former, you would do well to use djbdns: http://cr.yp.to/djbdns.html
    If the latter, then use [djbdns and] IPSec.

    I'm afraid I'm not clear on what exactly you are doing.

    Do you just need a caching DNS server for your own networks, or do you also wish to host your own domains' authoritative records?

    If the former, you need to allow inbound packets to high udp ports from source udp port 53 in order to receive remote DNS servers' replies to your queries; you should also allow non-SYN tcp responses with the same port specifications for those few cases where your dns clients will have to re-try queries over TCP, and for zone transfers.

    If the latter, then you need to do the above _as well as_ allow inbound 53/udp.  Whether you allow inbound 53/tcp depends on your records and whether you need to allow zone transfers.  As someone else has already noted, "it's not just for zone transfers."  However if your DNS replies are <= 512 bytes then clients won't need to re-try over tcp.  IOW, most sites don't need to allow TCP queries... YMMV though. (See also: http://cr.yp.to/djbdns/faq/tinydns.html#tcp )
