I have my bonding interface with name, agee I have to copy its setting to br-ex adapter, but when I do I lose connectivity and I can't do anything how I do this? I do this setting on the br - ex adapter.
DEVICE=br-ex
DEVICETYPE=ovs
TYPE=OVSBridge
BOOTPROTO=static
IPADDR=172.17.85.101
NETMASK=255.255.255.0
GATEWAY=172.17.85.254
DNS1=8.8.8.8
ONBOOT=yes

I am trying to move my organisation from Centos7 to Centos8 and Rocky linux which have network manager. Due to the multi-homed system I am trying to setup scriping to autoconnect since out of the box NM loses connectivity but I am a bit stuck.
If I try to run For example
nmcli c modify ens3 "IP4.DNS[0]" "8.8.8.8"
I get the Error: invalid or not allowed setting 'IP4': 'IP4' not among [connection, 802-3-ethernet (ethernet), 802-1x, dcb, sriov, ethtool, match, ipv4, ipv6, hostname, tc, proxy]. From what I understand NM is unable to modify these settings but I not understand why, or who set them up. I suspect it is somewhere in cloud init or in the dhcp-reply ??
nmcli connection show ens3 | grep IP4
IP4.ADDRESS[1]:136.ZZ.XX.XXX/23
IP4.GATEWAY:136.ZZ.YY.YY
...
IP4.DOMAIN[1]:openstacklocal
[root#chkorocky syck]# nmcli c show ens3 | grep ipv4
ipv4.method: auto
ipv4.dns: --
ipv4.dns-search: --
ipv4.addresses: --
ipv4.gateway: --
Is there anyway to understand where these extra attributes come from? Somehow ipv4.XX do not get set up at all but instead other variables with similar names allow NM to work ?
I just got my retroflag gpi case working and set up. I have one small problem though. I can't connect my Pi to my WPA2-Enterprise network. I've tried a bunch of settings in wpa_supplicant.conf but can't get it to work.
Pi Model or other hardware: Raspberry Pi Zero W & Retroflag GPi Case
Power Supply used: Retroflag GPi's inbuilt.
RetroPie Version Used: 4.6.1

USB Devices connected: Retroflag GPi

Error messages received:
Can't see any error messages. Don't know where they appear. It just says IP-address Unkown in show ip.

This one for documentation: https://w1.fi/cgit/hostap/plain/wpa_supplicant/wpa_supplicant.conf
File: /etc/wpa_supplicant/wpa_supplicant.conf
Attachment of config files: (wpa_supplicant.conf)
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
country=SE
ap_scan=1
network={
ssid="Wifi-Name"
scan_ssid=1
identity="myusername"
password="mypassword"
key_mgmt=WPA-EAP
eap=TTLS
phase1="peapver=0 peaplabel=1"
phase2="autheap=MSCHAPV2"
}
I actually solved it just now.
For anyone wondering I managed to connect to the network on another machine (Ubuntu) and used Network Manager. I then checked the log (according to this link) with the command:
journalctl -u NetworkManager
This gave me this config for wpa_supplicant.conf:
country=SE
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
ap_scan=1
network={
ssid="Wifi-Name"
scan_ssid=1
bgscan="simple:30:-65:300"
key_mgmt=WPA-EAP WPA-EAP-SHA256
password="password"
eap=PEAP
fragment_size=1266
phase2="auth=MSCHAPV2"
identity="username"
proactive_key_caching=1
}
This might not work for everyone else since the configs are always different for every network. So be sure to do the same steps as I did if you can't get it to work.
So glad I finally got this, haha.
I want to add --sslAllowInvalidHostnames criteria to the mongo connection in Mule but cannot see how I can add this and only see a tick box for SSL.
How can I add this?
Mongo configuration:
<mongo:config name="Mongo_DB__Configuration" username="${mongodb.username}" password="${mongodb.password}" database="${mongodb.database}" host="${mongodb.host}" doc:name="Mongo DB: Configuration"/>
Thanks
The class org.mule.modules.mongo.Config (in version 4.1.0, can't confirm for others) simply checks for a system property called sslInvalidHostNameAllowed and sets the criteria accordingly.
Try adding -DsslInvalidHostNameAllowed=true to your java command used to launch Mule, or alternatively by adding wrapper.java.additional.<n>=-DsslInvalidHostNameAllowed=true to your wrapper.conf file (in MULE_HOME/conf) for standalone Mule instances.
I have been using Unity and teensy to perform serial communication for quite some time. And it has been working fine.
Now I changed my teensy board and thus the COM Port has changed on it.
Teensy is communicating perfectly in arduino and sending all the right signals when checked in serial monitor. But I am getting this error in unity.
> IOException: The port `COM11' does not exist.

Initially the com ports were single digit values such as COM4 or COM8 etc. But since I started getting twodigit COM Ports I started facing this problem. If I connect a teensy again with a single digit com port it works fine but does not detect COM50 etc.
How do I solve this?
If this is Windows OS then try to specify the COM port name as \\.\COM11
myPort= new SerialPort("\\\\.\\COM11",9600);
NOTES: This syntax also works for ports COM1 through COM9. Certain boards will let you choose the port names yourself. This syntax works for those names as well.
Use System.IO.Ports.SerialPort.GetPortNames() to see what names does the OS use for current COM ports. (I'm not sure if you're talking about .NET, but if you do this helps)
Use
foreach(string str in SerialPort.GetPortNames())
{
Debug.WriteLine(string.Format("Existing COM port: {0}", str));
}
For know the ports available
Currently, i can connect from the raspberry (raspbian) to my home wifi but when i try to connect to iphone (4s) hotspot i can't. Iphone is WPA2 Personal while my home network is WPA/WPA2 Personal. I suspect there's something wrong with my config but i really can't find what. Here's the relevant part in /etc/wpa_supplicant/wpa_supplicant.conf.
network={
ssid="iPhone"
psk="pass"
proto=RSN
key_mgmt=WPA-PSK
pairwise=CCMP
auth_alg=OPEN
}
For reference here's the config (working) for my home network (in the same file):
network={
ssid="wifi name"
psk="pass"
# Protocol type can be: RSN (for WP2) and WPA (for WPA1)
proto=WPA
# Key management type can be: WPA-PSK or WPA-EAP (Pre-Shared or Enterprise)
key_mgmt=WPA-PSK
# Pairwise can be CCMP or TKIP (for WPA2 or WPA1)
pairwise=TKIP
#Authorization option should be OPEN for both WPA1/WPA2 (in less commonly used are SHARED and LEAP)
auth_alg=OPEN
}
I think your network has not the same configuration as you set (for proto / pairwise). You might configure your network this way:
network={
ssid="iPhone"
psk="pass"
key_mgmt=WPA-PSK
}
The wpa_supplicant will find the correct configuration by itself.
Remove inverted commas & spaces from your iphone’s Name this will solve the problem
