Product Issues

There are three main issues to be aware of:

• In releases before 1.0.9 there is a bug which will sometimes cause the box to seize up and stop responding even to the console. Upgrade.
• In any release, you cannot set any of the three interfaces to the same subnet. You may receive a "file exists" error when you try. There is no workaround beyond "don't do that". On 1.0.9 when you try it in the config system, it will notice and prevent you.
• Some power adapters seem to have trouble "starting up" and need to be reinserted a couple of times in order to power the unit. We're corresponding with the power plug manufacturer about this. It appears that they have changed the supplies now to avoid the problem: if you have some issues, just retry a few times; request a replacmeent if too frustrating.
• If you UPGRADE (1.0.8->1.0.9) the default password mentioned in the documentation will not be set, you will need to set manually. Note (as it warns you) saved settings will be lost in general.

• Processing
  1. Added Interface watch (in bytes or rate)
  2. Added asymmetric network emulation
  3. Added 3-network emulation
  4. Can save named configurations
  5. Can now change the basic network emulation w/o resetting all state
  6. Fixed occasional system hang in bridge mode with mgmt0 in use
  7. Enabled configuration of queue length
• Monitoring Model only:
  1. Added "top talking applications"
  2. Convered Monitor to menu system
  3. Added nmap, dsniff 2.3 tools (libnet, libneds) - not added to menu
  4. Clarified some items, added some small additional stats
• Other
  1. Error message correction for gateway spec.
  2. Enabled telnet
  3. Faster bootup
  4. Spelling fixes
  5. For odd RTTs, cease rounding down, instead use N/2 and N/2+1 so total is N (i.e. 5ms delay is now 2ms is one dir, 3 in the other not 2ms in each)
• Setup/config
  1. Enable fixed/auto duplex settings on interfaces
  2. Enable display of duplex settings on interfaces
  3. Complain if routing setup causes overlaping subnets
  4. Set default password for wansimuser (NN2wansim)
  5. Can now change timezone (and if routing is setup to internet will set date via rdate)
  6. Added restore command to load factory defaults

However you upgrade, be sure the downloaded file retains its .gz extension (and is < 15 MB in size), if it is expanded by your web browser, then it will not fit on /tmp!

Once you have upgraded, note a few things that are normally taken care of in manufacturing, but which you will experience:

• The NN2wansim password will not be set automatically
• You will lose all config in the upgrade
• The first boot post-upgrade will take MUCH longer than normal (5+ minutes)
