Reconfiguring the 6611 Routers.

The 6611 routers are MtPilot and Sarah. They use a bizzare interface for configuration. This page explains how to do some of the basic tasks of reconfiguring them.

Logging In:

  1. Telnet to the machine. You will get the message saying you're connected and then things will appear to hang. This delay is normal. It make take a minute or two but it will connect.
  2. Log in as "dirt". Use the "old root passwd". Find someone who knows it if you don't.
  3. The system is configured to expect some strange terminal type and will ask you if this is ok. Type "NO" and choose your terminal type from the menu presented. (I usually choose "8. Vt100" when I'm connecting through an xterm and that seems to work well.)

Cursor Movement:

^n moves to the next line.

^p moves to the previous line

Esc-# where # is a digit gives the effect of the corresponding function key.


Configuration Examples:

Changing the IP address/netmask of an interface:

  1. Log-in as described above.
  2. Select "Configuration" by moving your cursor onto that option and pressing return.
  3. Select "System Manager Configuration Utility".
  4. Hit return again, to confirm that you want to change the system configuration.
  5. Choose " Set Configuration Values for Single Object". (You could choose " Show Configuration Values for Single Object" if you just wanted to look at the configuration.)
  6. Choose " Port Level Parameters" in the pop-up menu. (An interface is a "port" in IBM 6611 terminology).
  7. Choose the slot of the interface you want to change. You may have to guess and look at the interface's configuration to see if it's the one you want to change. I believe they are numbered in the same order they are installed in the machine though. For this example, I choose " Slot 2 :: 6611 Ethernet".
  8. Choose the appropriate Port. (All of the interfaces I've seen only have one Port.)
  9. Choose "IP Parameters".
  10. Change the desired fields. It's best just to completely retype the values you want instead of changing part of a field (e.g. just the last octet of the ip address.) There screen image isn't always clear. You may want to hit ESC-2 to redraw the screen. When you hit return your changes will recorded but not applied. Hit ESC-3 to leave the "COMMAND STATUS" window.
  11. Hit ESC-3 repeatedly to back out of the menus until you reach "Configuration".
  12. Choose "Commit Changes".
  13. Choose "applied and unapplied changes".
  14. Hit return on the "Are You Sure?" menu to commit your changes.
  15. After "the configuration is committed" appears, hit ESC-3 to back out to the System Manager menu.
  16. Hit ESC-0 to logoff.

Examining the IP routing information

  1. Log-in as described above.
  2. Select "Operations" by moving your cursor onto that option and pressing return.
  3. Select "Routing Information".
  4. Choose " Route Tables".
  5. Choose " IP" in the Protocol Name pop-up menu.
  6. The routing information will be displayed
  7. Hit ESC-3 repeatedly to back out of the menus until you reach "System Manager".
  8. Hit ESC-0 to logoff.

 Changing ARP table entries

  1. Log-in as described above.
  2. Select "Operations" by moving your cursor onto that option and pressing return.
  3. Select "ARP Table Management".
  4. Choose " Add IP ARP Entry".
  5. Choose the interface that is connected to the network you want to use this arp entry on (note: only "active" interfaces are shown. If an interface is not connected to a network it doesn't show up in this list.)
  6. You can edit the IP address and hardware address fields (as well as the other fields, presumably). When you hit enter your changes will be applied.
  7. Hit ESC-3 repeatedly to back out of the menus until you reach "System Manager".
  8. Hit ESC-0 to logoff.

 Changing IP Routes (work in progress - just use up to looking at the static route, changes don't seem to work):

  1. Log-in as described above.
  2. Select "Configuration" by moving your cursor onto that option and pressing return.
  3. Select "System Manager Configuration Utility".
  4. Hit return again, to confirm that you want to change the system configuration.
  5. Choose " Add Configuration Element to a List Object". (You could choose "List Configuration Elements in a List Object" if you just wanted to just look at the configuration.)
  6. Choose " BoxLevel Parameters" in the pop-up menu. (An interface is a "port" in IBM 6611 terminology).
  7. Choose "List of IP Static Routes".
  8. Change the desired fields. It's best just to completely retype the values you want instead of changing part of a field (e.g. just the last octet of the ip address.) There screen image isn't always clear. You may want to hit ESC-2 to redraw the screen. When you hit return your changes will recorded but not applied. Hit ESC-3 to leave the "COMMAND STATUS" window.
  9. Hit ESC-3 repeatedly to back out of the menus until you reach "Configuration".
  10. Choose "Commit Changes".
  11. Choose "applied and unapplied changes".
  12. Hit return on the "Are You Sure?" menu to commit your changes.
  13. After "the configuration is committed" appears, hit ESC-3 to back out to the System Manager menu.
  14. Hit ESC-0 to logoff.
