Error executing miniccnx

[josevl]

Hello, I have successfully build Mini-CCNx in a Ubuntu 12.04 LTS (with CCNx 0.8.2).

I have tried to recreate tutorial example (h1, h2 y r1) with miniccnxedit, but when I try to run miniccnx, it trows the following error messages:

$sudo miniccnx
Parse of miniccnx.conf done.

It seems to be the problem is in InfluxDB, but it is running ok:
$sudo /etc/init.d/influxdb status
influxd Process is running [ OK ]

Any suggestion is welcome?

Hello josevl,

Which version of InfluxDB are you using? Did you install the InfluxDB
Python Libraries?

Best regards,
Caio
