Double node id

I hope I can explain this. I have 4 3g dishes. 1 points to 2, 2 and 3 are on the same tower and 3 points to 4. 1 and 2 are on the same frequency and 3 and 4 on the same freq but different then 1 and 2. At the tower 2 and 3 are connected dtd thru a Netgear 105e. All was good until I decided to change the id headings on the nodes. I confused 2 and 4 and changed the distance setting. I was on 2 and thought I was on 4 and changed the name and distance which should have been 4 km to 32 km. Nr 4 I changed the name and distance to 4 km and when I rebooted, I lost it. Realizing this, I drove up to 4 and reset the name and distance back to the correct name and distance. I then corrected 2 as well. Now the problem. When I look at node 3, I cannot see 4 and 2 has the new name plus the old name. If  I unplug 2 from the switch, I can see 4 no problem. I plug 2 back in and 4 disappears. I have reset 2 twice with no joy. I cannot get the double name off 2 and cannot put 2 in the system without losing 4.  Everyone in our group has given up. I am at a loss as to what to do. Any ideas?

My head is spinning
Actually, I believe what you are seeing is an issue where the old names are still being held in the OLSR tables.  Are these the only nodes in the system?  Your best bet may be to power everything down for about 30 minutes and then power them all back up and see that you see.

I haven't tried powering down
I haven't tried powering down. I will do so and get back. Thanks

Powering down didn't help.

You have 4 nodes; node1,

You have 4 nodes; node1, node2, node3, and node4.
Nodes 2 and 3 are DTD connected.
"All was good until I decided to change the id headings on the nodes."
Do you mean in '/cgi-bin/setup' you changed the 'Node Name' value?
"I drove up to 4 and reset the name and distance back to the correct name and distance."
When you say 'reset' do you mean you clicked 'Reset Values' or
did you mean you set new values, clicked 'Save Changes', and clicked 'Reboot' ?
Which procedure when you say 'I have reset [node]2 twice with no joy.'? (('Reset Values' or 'Save Changes') and 'reboot)
When you say "If I unplug 2 from the switch, I can see 4 no problem.",
to what node is your terminal connected? (node3?) and,
perhaps you should power down node2 instead of only unplugging the ethernet cable.?
When you 'power down' a node, is it for at least 30 minutes?
If the node is not DTD connected:
Instead of powering down so that neighbor nodes forget the Node Name and routing,
you can change frequency or bandwidth for 30 minutes. You will need to be able to
set a neighbor node to match to bring settings back later.
Hope this helps,
Chuck

First question- changed node
First question- changed node name in setup
2 - Went into setup, set new values saved changes, reboot.
3 - Reset, put in new values, saved changes, reboot.
4 - node 3
5 - 1 hr.
I replaced the m3 rocket on #2 dish with another and the system is operating as it should. Maybe if the bad one sits on the shelf for awhile it will restore. Ha.

Whenever you change a nodes
Whenever you change a nodes name you will want to leave it unplugged as noted above for around 15-30 minutes depending on mesh size these generally are more than long enough to allow the old name to purge.


Any new node that comes in the mesh (or gets disconnected for similar time) will also purge the name, but it is often easiest to just power down the node that is changed instead of trying to power down the entire mesh.

This is AREDN->ticket:157. It’s a nasty little flaw from a UI standpoint but minimal flaw in the grand scheme of other issues I’m working (slugbug for one.)  I would love to get time to look at it but I spend so much time dealing with my co-developers who keep pushing features over bug fixes I don’t get much time to work these issues.
