networking - Checking small network in mininet by Opendaylight -

-

i have question checking small network opendaylight

i not sure why can't accress opendaylight menu created mininet

i using windows 7 , vmware player run mininet , opendaylight(on ubuntu).

first, run ubuntu run opendaylight ( checked 120.0.0.1:8080 working) second, run mininet ip address.( "192.168.139.128") third, based on ip address , run 2 putty run wireshark , building small network

i used sudo mn --mac --controller=remote, ip=192.168.139.128, port=6633.

it build small network. because can check node infor command "nodes" , "dump" enter image description here

however, when go ubuntu vm , access opendaylight 192.168.139.128:8080 (it given ip mininet)

enter image description here

i sure sure why happen. there possible reasons ?

just in case, if facing same issue, change network adapter settings in vmware use bridge mode.

from official page

important troubleshooting - if running virtualbox on same host/desktop controller running, , trying start virtual network on mininet vm produces error: "unable contact remote controller @ ...", following resolves problem:

  1. in virtualbox, go file-preferences-network , make sure have @ least 1 interface defined host-only. lets name vboxnet0

  2. in virtualbox - mininet vm - settings - network, check adapter of type host , , connected interface item 1 (vboxnet0)

  3. on host controller , virtualbox run, "ifconfig" command display network interfaces on machine.

search interface in item 1 (vboxnet0 in our example) take ip address specified there (most 192.168.56.1 - default), , correct remote controller ip address use when starting virtual network in mininet vm stated in example above (--controller=remote,ip=192.168.56.1) .

  1. if still not able connect, might want consider temporarily disabling firewall on host running controller (on linux, example, iptables -f job)

  2. sometimes, way start mininet problem, not give error, not connect remote server. here wrong example:

    sudo mn --topo=tree,3 --mac --switch=ovsk --controller=remote, ip=192.168.16.10

here correct example:

sudo mn --topo=tree,3 --mac --switch=ovsk --controller=remote,ip=192.168.16.10

the difference "space" between "remote," , "ip".

i'm trying subclass qstyleditemdelegate remove focus rectangle in qcombobox . even though i'm calling base implementation of paint function , nothing else, result different. looks if parts of style-sheet influence bounding box of item taken consideration. class pstyleditemdelegate(qstyleditemdelegate): def __init__(self, *args, **kwds): super(pstyleditemdelegate, self).__init__(*args, **kwds) def paint(self, *args, **kwargs): qstyleditemdelegate.paint(*args, **kwargs) what have paint unmodified qstyleditemdelegate ? as suggested tried replacing pyside pyqt4 , works, appears bug. update pyside 1.1.2 1.2.1 result same. unfortunately switch breaks other parts of code, if there no other suggestions i'm going accept answer. edit bug tracked here
