I am running GNS3 0.7.4 on an Ubuntu Release 11.10 ( Oneiric).
Whenever I save a topology with more than one 3700 series router, I always have an error when trying to get back my topology on a later date.
When I run the command dynagen topology.net the below is what I get as my output
Reading configuration file...
*** Warning: Could not connect to dynamips server 127.0.0.1:7200
*** Error: errors during loading of the topology file, please correct them
Press ENTER to continue
What could be the problem ??
