I have two Cisco Wireless LAN Controllers and Unimus was able to discover them, but the backup job is failing.

Could you please run Unimus in debug mode and then run a backup on one of the failing WLCs?

On Linux:

Code: Select all

sudo su
service unimus stop
cd /opt/unimus
java -jar Unimus.jar \
--logging.level.net.unimus.core=TRACE \
--unimus.core.echo-ssh=TRUE \
On Windows:

Code: Select all

1) Download .jar distribution:
2) Stop Unimus service
If you are running the Portable version, skip this
3) Open an admin command prompt
4) change to folder where Unimus.jar was downloaded
5) Run "java -jar Unimus.jar --logging.level.net.unimus.core=TRACE --unimus.core.echo-ssh=TRUE --unimus.core.echo-telnet=TRUE"
6) Logs should be in the command prompt window
Please PM me the logs from the debug run.

Same Problem here on a Cisco 5508 physical appliance (v8.0.133.0), backup user has read-only privileges.

I sent you the logs.

Update for anyone reading this topic in the future:

In both of these cases, the problem was that the WLC took too long to start outputting the backup.
Unimus was therefore reaching timeout and failing the backup job.

To diagnose, simply measure how long it takes the WLC to start outputting data for the "show run-config startup-commands" command.

To fix this, timeouts can be adjusted:
