Mgt int routing Issues - RPI #42

Closed darwincastro closed 3 years ago

darwincastro commented 3 years ago

Hi Nigel, I hope you are doing well.

I've created twice a fresh raspbian image for my RPI, I followed step by step the deployment doc, but I'm failing in the last step in the probe config, and I'm getting the same exact warning route error under cat /var/log/wiperf_agent.log

(It's looks like the mgt interface will be route using the loopback int)

My routing table as follow:

default via 192.168.50.1 dev wlan0 192.168.50.0/24 dev wlan0 proto kernel scope link src 192.168.50.81 192.168.50.0/24 dev eth0 proto kernel scope link src 192.168.50.80

My ip conf:

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000 link/ether dc:a6:32:1e:61:30 brd ff:ff:ff:ff:ff:ff inet 192.168.50.80/24 brd 192.168.50.255 scope global dynamic eth0 valid_lft 85060sec preferred_lft 85060sec inet6 fe80::dea6:32ff:fe1e:6130/64 scope link valid_lft forever preferred_lft forever 3: wlan0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000 link/ether dc:a6:32:1e:61:31 brd ff:ff:ff:ff:ff:ff inet 192.168.50.81/24 brd 192.168.50.255 scope global dynamic wlan0 valid_lft 85056sec preferred_lft 85056sec inet6 fe80::dea6:32ff:fe1e:6131/64 scope link valid_lft forever preferred_lft forever

Under ./config.ini (It's the same result using mgt_if: wlan0 or mgt_if: eth0)

My current conf:

; ==================================================================== ; General settings - any changes to this section should only be ; made when in classic mode (not while in wiperf mode) on the WLAN Pi ; ==================================================================== [General] ; global test mode: 'wireless' or 'ethernet' ; ; wireless mode: ; - test traffic runs over wireless interface ; - management traffic (i.e. result data) sent over interface specified in mgt_if parameter ; ethernet mode: ; - test traffic runs over ethernet interface ; - management traffic (i.e. result data) sent over interface specified in mgt_if parameter ; probe_mode: wireless

; ------------- ethernet mode parameters ------------ ; eth interface name - set this as per the output of an ifconfig command (usually eth0) eth_if: eth0 ; ---------------------------------------------------

; ------------- wireless mode parameters ------------ ; wlan interface name - set this as per the output of an iwconfig command (usually wlan0) wlan_if: wlan0 ; ---------------------------------------------------

; -------------mgt interface parameters ------------ ; interface name over which mgt traffic is sent (i.e. how we get to our management ; server) - options: wlan0, eth0, ztxxxxxx (ZeroTier), lo (local instance of Influx) mgt_if: wlan0 ; ---------------------------------------------------

; --------- Common Mgt Platform Params ------- ; set the data exporter type - current options: splunk, influxdb, influxdb2 exporter_type: influxdb ; --------------------------------------------

Nigel, what should I check? I've tried creating new default route pointing all the traffic to the ethernet or wlan without luck! Also, I tried only using the internal wlan NIC without luck.

Thanks in advance, and please let me know if you need another detail.

P.D I love this project!

I found the issue (it was a typo under the exporter_type) Now, everything is working like a rock!!!!

Thanks, DC
