I've recently attempted to connect (to the internet) via a Bridge connection rather than my wired Ethernet connection (Desktop). I have done this so that all my kvm guests have bridge connections and are in the same ip range as my host (followed various posts on web). Everything appears ok (everything in same ip range and has connectivity) except that when I first boot to my Desktop I have no internet connectivity for about 25secs - and then bang, I'm on. Is this normal in that I'm now using a software virtual bridge device so it takes time (@25 secs) to sort everything out?

pass traffic between 2 interfaces on same box
Hello. I'm asking for some networking expertise, please.
I have set up a small DLNA server, on a NanoPi NEO3, running Ubuntu Core 18.04.
On the NEO3 I have successfully set up the DLNA server (minidlna), samba, a wifi interface, an ethernet interface, and a DHCP server running on the ethernet interface.
The ethernet interface is connected to the DLNA endpoint device (an Audio Pro C5). I have set a static IP address for this interface of 10.0.0.1, and its DHCP server hands out IP address 10.0.0.2 to the DLNA endpoint device.
The NEO3's wifi interface is configured to connect to my home router, with a static IP address of 192.168.1.102.
I'm running a DLNA controller app (BubbleUPnP) on my Android phone, connected to this same wifi router.
So far, so good. The stumbling block is that I need to pass network traffic between the two interfaces (eth0 and wlan0) of my NEO3 for this to all work. After reading many HOWTO's on the web, I tried two different approaches:
i) creating static routes with "ip route"
then added this to /etc/sysctl.conf
ii) Network Address Translation with iptables
In both cases, from my phone (or any other device on the 192.168.1.x network) I could not ping 10.0.0.1.
Can anyone please tell me which way to go with this?
Thanks.

WiFi issues Ubuntu 20.04 Dell XPS 15 (9570)
Hi all,
some times ago, I've installed Ubuntu (18.04) on my Dell XPS 15 and everything was fine.
After upgrading to 20.04 I'm having some serious issues with the Wireless interface.
Basically after some random period the wifi is connected, it crashes and I cannot do anything else other than reboot the system.
If I go to the WiFi settings it appears "NetworkManager is not running".
If I try to input the following command "lshw -C network" it gets stuck and I have to close the terminal.
I don't know how to troubleshoot this issue.
the product is the ACA6174 802.11ac Wireless Network Adapter (I saw this because immediately after I boot the system, the command "lshw -C network" works properly).
Thank you in advance

[ubuntu] VLANs advantages for Private Users
I have just started experimenting with VLAN on my router.
With the exponential growth of IoT now it is not unusual for a family household to have 30+ (That may be low a estimate) devices connected to the LAN. All needed routing, most DHCP, broadcast messages etc. I do find with mine on occasions a device is connected to the internet but won't respond locally. Sometimes clearing the router's ARP record clears it but usually a reboot is required.
So am wondering; for a home network is a VLAN a good idea? Would a normal user notice any difference? Appreciate the security aspect of isolating certain machines of devices but just curious what other forum members think.

[ubuntu_studio] NetworkManager fails to start
Ubuntu 20. Up until 06:18 EST on Feb 13, 2021, NetworkManager was running fine, getting an IP from DHCP on my router. Here is output from journalctl for hostname coot
Every attempt to start NetworkManager since then has failed. The next day, I noticed that the connection light on the ethernet switch was not lit for the cable to my machine. I tried a usb-to-ethernet adapter and the switch port lit up just fine. Without a NetworkManager, I still didn't have connectivity.
I bought a PCI ethernet card with an Intel chip. Installed it, plugged in the cable and the port lit up as it should. When I rebooted (approx. noon local time on Feb 15) I had no connectivity. After some hours I saw an article describing how to run dhclient manually. dhclient got the network going again, routes and all. My new card is working, and I'm online again. I have rebooted several times since then, and I have repeatedly tried restarting NetworkManager with systemctl. BUT NetworkManager still won't start. The same error message appears in journalctl output. I have to run dhclient manually every reboot.
Do I need NetworkManager running? My new ethernet card is visible in 'lshw' output, but dhclient doesn't start until I run it manually.
What do I do next?

Cannot pair bluetooth mouse
I haven't found any solution yet so I am posting this.
Problem: I cannot pair my Logitech MX Master mouse via bluetooth to my new laptop with a fresh install of Ubuntu 20.04.2.
I believe the problem is not related to the specific mouse since it has always worked on Ubuntu 18.04 (other machine) and it is working on this same machine under Windows.
Other bluetooth devices (phone, earbuds) have been detected and paired without any problems.
Thank you in advance for any help you can provide.

Can't broswe Windows Shares from Ubuntu
Hi
I'm running Ubuntu 20.04.2 LTS
I can connect to a Windows server to display the shares, but I cant browse any of them. It says:
Unable to access locations: Failed to mount Windows share: Invalid argument.
From researching it, I've made lots of tweaks to /etc/samba/smb.conf - I've lost track of all the changes. I wish I made a backup of the original file so I could start again, but below is a paste of the exact contents right now.

[ubuntu] Using Pi-Hole within a VLAN
Folks,
Had Pi-Hole running on my network for some time with no issues. I have started experimenting with VLAN which, I am assuming this is the norm, creates another subnet.
If I create the VLAN without enabling isolate then Pi-Hole is seen, if I choose to isolate then it is not seen on the VLAN but obviously is on the original subnet.
Being new to VLAN I am not sure why one would create a VLAN and then not isolate but I may be missing some pros and cons.
Now I've tried using ip addr add to give the adapter a second IP address but, although it works fine if second address within same subnet it does not appear to work if the extra IP is within the second VLAN subnet.
There do not appear any obvious router settings to achieve this, any suggestions appreciated.

IPv6 on Ubuntu router; can't access LAN
Hey all,
I have a router running Ubuntu 20.04 that is statically configured via netplan for the LAN interface and dhcp/dhcp6 for the WAN interface. Everything works as expected EXCEPT the router itself cannot use/ping via IPv6 on the LAN side.
To be clear: IPv6 and IPv4 work to WAN side for the router, machines on the LAN side have fully working IPv6 and IPv4, and the router has working IPv4 on the LAN, it is only the router that is unable to use IPv6 on the LAN side. My ISP has provided a /64 for IPv6 usage and I have dhcp (IPv4), dhcp6 (IPv6), and radvd all set up and working.
I've tried assigning a gateway6 address to eno1 (the LAN side) but networkctl tells me "eno1: Could not set route: Gateway can not be a local address. Invalid argument"
If I leave gateway6 out of the config there are no errors but the router can't use IPv6 on the LAN yet machines on the LAN can. It seems like the router can't figure out it is it's own route for the /64.
My netplan config looks like this:
network:
version: 2
renderer: networkd
ethernets:
enp2s0:
macaddress: XX:XX:XX:XX:XX:XX
dhcp4: true
dhcp6: true
dhcp4-overrides:

[ubuntu] Ubuntu Linux 20.04 - Bluetooth neckband microphone not working
Hi all,
I own a Dell Inspiron 3543 laptop since June 2015. This laptop came with an integrated microphone. Recently, in Oct. 2020 IIRC, I had to record a short video message and I realized that the footage has static. My laptop currently has Ubuntu Linux 20.04 64 bit.
I used a pair of headphones + microphone to record a short video message. When I play back the footage, it has static. Maybe, behind the scenes, my headphones + microphone use the same integrated microphone and/or its drivers to record. So, no wonder the footage has static. BTW, I use application guvcview to access my integrated webcam to record footage. To me, it feels like the integrated microphone has a driver issue. I looked around in Google to see if there is a solution to my problem. Some posters suggested killing PulseAudio, specify the correct audio sample rate etc. I did these things and the static may have reduced but it is still there.
So, to circumvent the usage of the integrated microphone, I ordered a Bluetooth neckband with earphones and microphone. I could connect the neckband to my laptop effortlessly. The earphones work fine but the microphone doesn't. I recorded video footage but the footage has no audio; looks like no input to the microphone. I thought I received a defective neckband but when I paired the it with my Android mobile and made a call, the other person confirmed she could hear me. So, the microphone in the neckband works fine.
My configuration is -
Laptop hardware: Dell Inspiron 3543 Intel(R) Core i5-5200U CPU @ 2.2 GHz x 4; 8GB RAM; 1 TB HDD
Neckband: Boult Audio ProBass FlowX, Bluetooth 5.0
Software: Ubuntu Linux 20.04 (64 bit), guvcview, VLC 3.0.12.1
When I look at arecord, I see
So, is this a Bluetooth driver issue? How do I resolve this issue? Please let me know if you need more information. I appreciate any suggestions/pointers/insights. Thanks in advance for your help!

[ubuntu] Wired Ethernet not connecting to Ubuntu 18.04 server (wifi works)
Trying to determine the issue behind why my server (18.04) cannot connect to through the ethernet cable. It was was working fine a few days ago but after I attempted to do some re-wiring, the server could no longer connect to my network. I checked the wiring and did not see anything misplaced and even made sure everything was plugged in properly. What should I be looking for in the machine? Is there something simple I am over looking? My network provider is comcast business. Any help is appreciated.

SCP command hanging after completing file transfer
Hello all! I am trying to SCP a file from a machine running Ubuntu Server 20.04 to a windows 10 machine. My issue is that when SCP finishes transferring the file, it hangs and doesn't return the prompt until I press Ctrl+C. The file is successfully delivered to the destination. I've tried sending a file from the windows machine to the linux machine, and it works fine.
I've tried uninstalling and reinstalling openssh-client on the linux machine - no luck.
Running scp -vvv filename.txt usr@hostname.com:/file/dest yields:
If more information is required please let me know! Thanks for the help it's greatly appreciated! Also I apologize if this is in the wrong location.

[server] Desconfigurada red al reiniciar maquina
Saludos amigos, un buen día para todos.
Deseo consultar sobre el siguiente problema:
Tengo un servidor con 4 tarjetas de red, ubuntu server 20.04, tres de ellas en uso, cada una con ip statica, y conectadas a un proveedor de internet diferente. Cada vez que reinicio la maquina la configuración de red al parecer cambia, pues debo cambiar físicamente los cables de red entre tarjetas hasta dar con la ubicación correcta de cada cable para que las tres conexiones de red funciones.
Acudo a ustedes solicitado ayuda para dar solución a este problema y poder reiniciar la maquina sin que la configuración de red cambie. Adjunto configuración actual de red.
auto lo ens1 eth0 eth2
iface lo inet loopback
# The primary network interface
allow-hotplug ens1 eth0 eth2
# Red fibra optica
iface ens1 inet static
address 192.168.1.100
netmask 255.255.255.0
gateway 192.168.1.1

Logging Connection to a Website
I have a problem connecting to a particular website. IS there a way to get meaningful logs of the interaction between my browser (I don't care which one) and the web sites.

SSH to virtual machine works only in one specific way
I have Ubuntu 20.04 installed on VMware Workstation 16 Player. I installed SSH server. To test it I did not use any key-pair, but only password.
From the Windows host the only way I can SSH into the machine is by using the command "ssh username@<LAN IP address*>" (*address as seen in ip a near inet)
If I try to use the same command from another PC I will get "ssh: connect to host localhost port 22: Connection timed out" (But that's obvious, because the IP is internal for the same network of the virtual machine and the Windows host)
But, If I try to use "ssh username@localhost" (from the Windows host)I get "ssh: connect to host localhost port 22: Connection refused"
Also, If I try to use "ssh username@<public IP address>" I get"ssh: connect to host localhost port 22: Connection refused"
To sum it up, the only way I can SSH to this virtual machine is from the host it runs from, and only using "ssh username@<LAN IP address*>"
*address as seen in ip a near inet
How to fix it? how to be able to SSH to it from other PCs on the internet as well?
Thanks
