12:46 +0800 <PoWen>: hello
12:46 +0800 <PoWen>: anyone can see me?
12:51 +0800 <hwchiu>: yes
12:51 +0800 <hwchiu>: i can
13:03 +0800 <PoWen>: hi
13:03 +0800 <PoWen>: 怪怪
13:03 +0800 <PoWen>: 失聯好幾天，連不上來
13:03 +0800 <PoWen>: ha
13:03 +0800 <PoWen>: slack那邊倒是比較少
13:14 +0800 <hwchiu>: 恩恩
14:27 +0800 <PoWen>: 這裡有對交大NBL
14:27 +0800 <PoWen>: 很熟的嗎
14:27 +0800 <PoWen>: 小飛機？
14:42 +0800 <hwchiu>: beachdog勒
15:05 +0800 <jamesLiao>: 午安
15:05 +0800 <jamesLiao>: 請問一下
15:05 +0800 <jamesLiao>: ovs可以手動去加queue嗎？
15:06 +0800 <hwchiu>: 可
15:07 +0800 <jamesLiao>: ！
15:07 +0800 <jamesLiao>: 哈哈 那要怎麼加？
15:08 +0800 <hwchiu>: http://hwchiu.logdown.com/posts/197231-config-qos-on-ovs-with-floodlight
15:08 +0800 <sdnds-tw_Bot>: ==> Config Qos on Ovs with Floodlight « hwchiu's Blog
15:09 +0800 <jamesLiao>: hwchiu大 我是在自己架的環境
15:09 +0800 <jamesLiao>: 不是用mininet耶
15:09 +0800 <jamesLiao>: 還是都一樣？
15:09 +0800 <hwchiu>: 一樣
15:09 +0800 <hwchiu>: ovs-vsctl
15:10 +0800 <hwchiu>: 這是OVS的工具
15:10 +0800 <hwchiu>: mininet只是借用OVS
15:10 +0800 <jamesLiao>: 喔喔
15:11 +0800 <jamesLiao>: 所以用ovs-vsctl在ovs上建queue就是了？
15:11 +0800 <hwchiu>: 恩恩
15:11 +0800 <jamesLiao>: 抄收
15:12 +0800 <jamesLiao>: 感謝！
17:40 +0800 <jamesLiao>: ovs有把特定的port number導到特定的queue的功能嗎？
17:40 +0800 <jamesLiao>: 比方說我要把port 1000讓他跑到queue1這樣
17:46 +0800 <hwchiu>: flow?
17:46 +0800 <hwchiu>: flow match & actions
17:48 +0800 <jamesLiao>: ?
17:49 +0800 <hwchiu>: 用match去比對port=1000的
17:49 +0800 <hwchiu>: 然後action設定enqueue
17:49 +0800 <hwchiu>: 導入某個queue
19:13 +0800 <John_irc>: 是說有port 1000嗎?! XD
19:18 +0800 <jamesLiao>: 哈哈 假設的啦
19:28 +0800 <_devnet_>: Hi
19:29 +0800 <_devnet_>: I am setting up openvswitch 2.3.0 on TP-Link WDR3600 router running openwrt
19:30 +0800 <_devnet_>: Openvswich is running and is able to communicate with controller
19:30 +0800 <_devnet_>: but after i add the wlan interfaces to ovs bridge, i can not connect to it anymore
19:31 +0800 <_devnet_>: connection get stuck at "obtaining ip address"
19:31 +0800 <_devnet_>: nothing happens after that
19:31 +0800 <_devnet_>: can you please tell me how to debug this issue
20:50 +0800 <_devnet_>: Hi
20:58 +0800 <hwchiu>: hi
20:58 +0800 <hwchiu>: pichuang: dlinking, do you have any idea about that ?
22:14 +0800 <pichuang>: how do you connect to tp-link wdr3600?
22:14 +0800 <pichuang>: wlan or lan?
22:19 +0800 <hwchiu>: _devnet_:
22:27 +0800 <pichuang>: hwchiu: 我英文超爛的 如果有非常奇怪的錯誤 幫忙訂正一下
22:27 +0800 <pichuang>: xd
22:33 +0800 <_devnet_>: through lan
22:35 +0800 <pichuang>: how many ports do you have?
22:35 +0800 <pichuang>: 5 or 4 ?
22:35 +0800 <pichuang>: if you have 4 ports
22:36 +0800 <pichuang>: try to add 3 ports into ovs-bridge, the other don't add to it.
22:36 +0800 <pichuang>: and you need bind one ip on the other port
22:37 +0800 <pichuang>: control your tp-link by that.
22:37 +0800 <_devnet_>: i have 5 ports
22:38 +0800 <_devnet_>: 4 lan and 1 wan
22:38 +0800 <pichuang>: ok
22:38 +0800 <_devnet_>: i need to use openvswitch for wlans
22:38 +0800 <_devnet_>: i have 2 wlans
22:38 +0800 <_devnet_>: 2.4 and 5 GHz
22:38 +0800 <pichuang>: who send dhcp?
22:39 +0800 <_devnet_>: i didnt get ur qn
22:39 +0800 <_devnet_>: please elaborate
22:39 +0800 <pichuang>: hmmm
22:40 +0800 <pichuang>: what's your ovs-bridge ip?
22:40 +0800 <pichuang>: do you know that?
22:40 +0800 <_devnet_>: i have set it to 192.168.1.1
22:40 +0800 <pichuang>: ok
22:40 +0800 <_devnet_>: and then removed the ip from eth0.1
22:40 +0800 <pichuang>: ok
22:41 +0800 <pichuang>: can you paste your `ifconfig` result?
22:41 +0800 <_devnet_>: one second
22:49 +0800 <_devnet_>: sorry for the delay

22:50 +0800 <hwchiu>: pichuang: 你請他貼gist之類的?
22:50 +0800 <hwchiu>: _devnet_: hi, could you use the paste service like gist to post your config ?
22:51 +0800 <_devnet_>: br0 is ovs bridge
22:51 +0800 <_devnet_>: sorry
22:52 +0800 <pichuang>: hwchiu: xd
22:52 +0800 <pichuang>: hwchiu: 我好想睡覺
22:52 +0800 <pichuang>: - -
22:52 +0800 <pichuang>: 他應該是沒設好ip
22:52 +0800 <hwchiu>: 等他一下XD 你加油
22:53 +0800 <pichuang>: 怎麼辦 他是貴寶地第一個歪國人

22:54 +0800 <sdnds-tw_Bot>: ==> ifconfig
22:54 +0800 <_devnet_>: ifconfig details
22:55 +0800 <pichuang>: ovs-vsctl show ?
22:56 +0800 <_devnet_>: https://gist.github.com/anonymous/cebeb63570f5bdbd9939
22:56 +0800 <sdnds-tw_Bot>: ==> ovs
22:57 +0800 <pichuang>: hmmmm
22:57 +0800 <_devnet_>: but when i try to connect to wlan
22:57 +0800 <_devnet_>: client is not getting the ip address
22:57 +0800 <_devnet_>: it waits for a while and then disconnects
23:00 +0800 <pichuang>: how to get your client ip?
23:00 +0800 <pichuang>: dhcp? manual?
23:00 +0800 <_devnet_>: the dhcp client should be running in the router right
23:00 +0800 <pichuang>: ok
23:01 +0800 <pichuang>: if you use openvswitch, maybe can not use dhcp service or nat service.
23:01 +0800 <pichuang>: any communication will be talk with controller
23:01 +0800 <_devnet_>: oh k
23:02 +0800 <pichuang>: your controller doesn't know how to handle this packet
23:02 +0800 <_devnet_>: but how does lan clients are able to get the ip address
23:02 +0800 <pichuang>: so you can not get any ip
23:02 +0800 <pichuang>: really?
23:02 +0800 <pichuang>: let me think.
23:02 +0800 <_devnet_>: yeah now i am connected to lan
23:03 +0800 <_devnet_>: and my laptop has ip address
23:03 +0800 <pichuang>: try 'ifconfig wlan0 0.0.0.0'
23:03 +0800 <pichuang>: 'ifconfig wlan1 0.0.0.0'
23:03 +0800 <_devnet_>: i already did that
23:03 +0800 <_devnet_>: there is no ip on wlan0 or wlan1
23:04 +0800 <pichuang>: you say you can get dhcp ip
23:04 +0800 <_devnet_>: yes for lan
23:04 +0800 <pichuang>: so any openflow flow on your device?
23:04 +0800 <_devnet_>: yeah
23:04 +0800 <_devnet_>: i can see
23:05 +0800 <_devnet_>: some flows in related to lan port
23:05 +0800 <pichuang>: wow
23:05 +0800 <pichuang>: it's interesting
23:05 +0800 <_devnet_>: wlan port is shown but no flows since there is no client connected to it
23:05 +0800 <_devnet_>: have you tried with wlan and ovs?
23:06 +0800 <pichuang>: yes
23:06 +0800 <pichuang>: i can controller any port on my device
23:06 +0800 <pichuang>: my device is dlink dir-835
23:06 +0800 <_devnet_>: can you please send me your network config
23:06 +0800 <pichuang>: ovs-ofctl show br0
23:06 +0800 <pichuang>: can you see wlan0?
23:06 +0800 <pichuang>: or wlan1?
23:07 +0800 <_devnet_>: https://gist.github.com/anonymous/cebeb63570f5bdbd9939
23:07 +0800 <sdnds-tw_Bot>: ==> ovs
23:07 +0800 <pichuang>: it's ovs-vsctl show result
23:08 +0800 <_devnet_>: sorry
23:08 +0800 <pichuang>: xD that's fine.
23:09 +0800 <_devnet_>: https://gist.github.com/anonymous/e4a764a541fde32bf1cb
23:09 +0800 <sdnds-tw_Bot>: ==> ofctl
23:09 +0800 <_devnet_>: i was playing around wlan0 interface
23:09 +0800 <_devnet_>: so it is not shown there
23:11 +0800 <_devnet_>: can you please send me your network config
23:11 +0800 <_devnet_>: send me /etc/config/wireless
23:11 +0800 <pichuang>: ok
23:11 +0800 <_devnet_>: please send me /etc/config/network

23:12 +0800 <pichuang>: i dont save wireless config, sorry
23:12 +0800 <pichuang>: but i just modify one line.
23:13 +0800 <pichuang>: umm.. delete one line.
23:13 +0800 <pichuang>: maybe you already saw that.
23:15 +0800 <pichuang>: hwchiu: 我兩眼快合上了
23:15 +0800 <pichuang>: hwchiu: xd
23:17 +0800 <hwchiu>: 加油ＱＱ
23:17 +0800 <hwchiu>: 有想法嗎
23:17 +0800 <pichuang>: 他的時區好像是+2
23:18 +0800 <pichuang>: 沒想法 我沒有用過他的方式
23:18 +0800 <pichuang>: 問題應該在那個eth0
23:18 +0800 <pichuang>: 我的config 是預設拿掉eth0 但他的還留著
23:19 +0800 <hwchiu>: 我沒有無線的經驗ＱＱ
23:19 +0800 <pichuang>: 其實不用想的這麼複雜 就是一個port
23:20 +0800 <hwchiu>: 我比較好奇為什麼lan順利wan失敗
23:20 +0800 <pichuang>: 2jo4
23:20 +0800 <pichuang>: 對啊
23:20 +0800 <pichuang>: 重點是還有流量
23:20 +0800 <pichuang>: ovs-ofctl 也有東西出來
23:21 +0800 <hwchiu>: 嗯嗯
23:22 +0800 <_devnet_>: you mean i need to disable the list network line right wireless config right?
23:22 +0800 <pichuang>: yes
23:22 +0800 <_devnet_>: yeah i already did that
23:23 +0800 <_devnet_>: no other changes?
23:23 +0800 <pichuang>: ok
23:23 +0800 <pichuang>: no
23:23 +0800 <_devnet_>: it works for you?
23:23 +0800 <pichuang>: just that
23:23 +0800 <_devnet_>: its really strange
23:23 +0800 <_devnet_>: then i created the ovs bridge manually and added all hte interfaces
23:24 +0800 <_devnet_>: eth0.1 is the switch with 2, 3, 4 , 5 ports
23:24 +0800 <pichuang>: maybe i need a lab to reappear your scenario.
23:24 +0800 <pichuang>: yes
23:24 +0800 <pichuang>: eth0.1 include 2,3,4,5
23:24 +0800 <pichuang>: a.k.a lan ports
23:24 +0800 <_devnet_>: what you mean by #admin port
23:24 +0800 <_devnet_>: yep
23:25 +0800 <_devnet_>: is that a probelm
23:25 +0800 <pichuang>: no
23:25 +0800 <_devnet_>: right now i am not worried controlling individual ports
23:25 +0800 <pichuang>: i dont add that port to ovs virdge
23:25 +0800 <pichuang>: s/virdge/bridge
23:25 +0800 <_devnet_>: you connect that port to controller right?
23:26 +0800 <pichuang>: yes
23:26 +0800 <pichuang>: hmm..
23:26 +0800 <_devnet_>: for normal tcp/ip
23:27 +0800 <pichuang>: the port let me connect to my device by normal tcp/ip.
23:28 +0800 <pichuang>: not for connect to controller
23:28 +0800 <pichuang>: it's in-band
23:28 +0800 <_devnet_>: then how do connect ap to controller?
23:28 +0800 <pichuang>: set one ip on ovs-vridge
23:29 +0800 <_devnet_>: where is your controller located?
23:29 +0800 <pichuang>: s/vrdige/brdige
23:29 +0800 <pichuang>: outside, public network
23:29 +0800 <_devnet_>: oh k
23:30 +0800 <pichuang>: it's not different to public network or private network.
23:30 +0800 <_devnet_>: yeah i got that
23:31 +0800 <pichuang>: i think that is not our problem of points
23:31 +0800 <pichuang>: xd
23:32 +0800 <pichuang>: maybe we need more test
23:32 +0800 <pichuang>: i will do a lab to reappear that.
23:32 +0800 <pichuang>: can you send your all config to me?
23:32 +0800 <pichuang>: /etc/config/*
23:33 +0800 <pichuang>: and your openwrt version
23:33 +0800 <devnet_>: sure
23:33 +0800 <devnet_>: one sec
23:33 +0800 <pichuang>: send to my email
23:33 +0800 <pichuang>: [email protected]
23:33 +0800 <pichuang>: hwchiu: 他這問題麻煩了
23:33 +0800 <pichuang>: 我沒遇過xdddd
23:34 +0800 <pichuang>: 感覺就是被openwrt雷到
23:34 +0800 <devnet_>: great
23:34 +0800 <devnet_>: i will send it your email id
23:34 +0800 <hwchiu>: maybe you can re-produce his problem by install the same version openwrt to your ap
23:35 +0800 <pichuang>: i need to find my tp-link XDDDD
23:36 +0800 <pichuang>: i dont know where it was.
23:36 +0800 <pichuang>: XDDDD
23:38 +0800 <pichuang>: devnet_: btw, what's your deployment options?
23:38 +0800 <pichuang>: do you try to deploy by out-of-band?
23:39 +0800 <pichuang>: i choice it now
23:39 +0800 <devnet_>: sorry
23:39 +0800 <devnet_>: i didnt get u r qn

23:44 +0800 <pichuang>: hwchiu: 有請翻譯精靈 XD

23:46 +0800 <devnet_>: nope
23:46 +0800 <devnet_>: public
23:46 +0800 <hwchiu>: so, the connection between the OVS and controller won't control by the OVS, right ?
