Unknown host #6

Closed Ali00 closed 8 years ago

Ali00 commented 8 years ago

Hello there,

I have tried to use Opennetmon in a mininet topology that has been designed in [MiniEdit] GUI, but unfortunately I've got the following error message;

Ping: unknown host h1

when I tried to ping h1 with other hosts and the same thing when I tried to ping any other host . So, could you please advise me in how to resolve this issue.

Many thanks,

Ali

Hello Ali00,

First of all, can I assume there actually is a host named h1? Can you try to ping using the corresponding IP-address of the host instead?

Furthermore, there have been issues using OpenNetMon in Mininet, I advise to use a physical setup of a few old machines instead.

I hope this helps.

Best, Niels

One more question :-)

Is it necessary to include the "openflow.discovery" module when run opennetmon ? like: ./pox.py openflow.discovery opennetmon.monitoring opennetmon.forwarding

Thanks,

Hi @Ali00,

Yes, you need the discovery module. If I remember correctly you can use the startup module to launch the right modules and preset the right variables.

Best, Niels
