Hi

 

I’m running three instances of UML as below;

 

Say node1:

./linux ubda=rfs1_cow,rfs mem=64M eth0=daemon,10:20:20:20:20:10,unix,/tmp/umlsw1 eth1=daemon,10:20:20:20:30:10,unix,/tmp/umlsw2 ieth2=daemon,10:20:20:20:40:10,unix,/tmp/umlsw3

 

  Eth0 is configured as 10.10.10.1/24

 

Say node2:

 

./linux ubda=rfs2_cow,rfs mem=64M eth0=daemon,10:20:20:20:20:20,unix,/tmp/umlsw1 eth1=daemon,10:20:20:20:30:20,unix,/tmp/umlsw2 eth2=daemon,10:20:20:20:40:20,unix,/tmp/umlsw3

 

  Eth0: 10.10.10.2/24

   Eth1: 11.11.11.1/24

 

Say node3:

 

./linux ubda=rfs3_cow,rfs mem=64M eth0=daemon,10:20:20:20:20:30,unix,/tmp/umlsw1 eth1=daemon,10:20:20:20:30:30,unix,/tmp/umlsw2 eth2=daemon,10:20:20:20:40:30,unix,/tmp/umlsw3

 Eth1: 11.11.11.2/24

 

I want to establish a tunnel from node1’s eth0 to node3’s eth1. There is a protocol stack running in all three nodes.

I can ping from 11.11.11.2/24 to node2’s interfaces, but not to node1’s eth0 interface.

OSPF detects the neighbors in all three nodes, and I also see the routes are installed.

 

Also I get a message, “send_sock sending to fd 4 Resource temporarily” in uml_switch.

(In one of the threads I saw “changing the priorities of the UMLs with respect to uml_switch”. If this is the solution, let me know how to

 Change the priority.)

 

May I know where I’m going wrong?

 

Thanks in advance

Raj
