Re: [openflow-discuss] Problem with SNMP in NOX

Thanks a lot KK for your help so far ! Just to verify, I compiled a fresh copy of sub-agents on a 12.04 ubuntu 64 bit machine. The compilation was successful without any fuss, however, when I run "/etc/init.d/openroads start ", I get an error: keepalive subagent missing I can't get the subagents

Re: [openflow-discuss] Problem with SNMP in NOX

Thanks again KK ! The script test_shift.sh on the link you provided does stop throwing error when shell type is changed from /bin/sh to /bin/bash. However, for the "make" command to use /bin/bash, I tried by inserting these lines (only one at a time) at the top of Makefile, but it keeps giving me

Re: [openflow-discuss] Problem with SNMP in NOX

Question: where did you compile the subagents? Try doing so on the PCEngine. Regards KK On 27 July 2012 14:32, Prabhat Tiwary wrote: > Hello KK ! > > Thanks a lot ! I had no idea how to debug this problem, so I did a fresh > setup of SNMP on my PC Engine Wifi AP from the scratch (by downloading

Re: [openflow-discuss] Problem with SNMP in NOX

Hello KK ! Thanks a lot ! I had no idea how to debug this problem, so I did a fresh setup of SNMP on my PC Engine Wifi AP from the scratch (by downloading fresh source codes and files). At the end when I run "/etc/init.d/openroads start", it throws me following error : /etc/snmp/keepalive_subagen

Re: [openflow-discuss] Problem with SNMP in NOX

Hi, I am not sure if this would solve your problem, but you should check the following: * make sure the subagents can work with the current version of OpenFlow on your AP. Which version of OpenFlow are you using? * make sure ap-subagents

Re: [openflow-discuss] Problem with SNMP in NOX

Thanks KK ! No, when I connect a client to the AP, I still have trap and wifi subagent running. Also, I tried a command "/etc/snmp/keepalive_subagent -x /var/agentx/master". But, it won't start the keepalive subagent. Regards ! Prabhat Tiwary McGill University On Mon, Jul 16, 2012 at 2:42 PM, k

Re: [openflow-discuss] Problem with SNMP in NOX

Tell me another thing: if you connect a client, does the trap or wifi sub_agents stop running? Regards KK On 16 July 2012 11:41, Prabhat Tiwary wrote: > Thanks a lot KK ! > > When we run "/etc/init.d/openroads start" in the AP, only trap_subagent > and wifi_subagent runs. > > KeepAlive subagent

Re: [openflow-discuss] Problem with SNMP in NOX

Hi Prabhat, (Please don't drop the mailing list) I am assuming the subagent is running and you have tested SNMP's agentx? The command line snmp trap bypass quite a few things needed by the subagent here. Does the keepAlive subagent actually works? That should be an indicator. Regards KK On 1

Re: [openflow-discuss] Problem with SNMP in NOX

Hi Prabhat, I am cc-ing the mailing list where these things should go to. I am not 100% sure where the problem is. Can you check that your SNMP agents is actually detecting that a client connects? Disconnection is a little filmsy from the WiFi side (i.e., a WiFi AP takes a long time to detect d
