Network icon missing

Hi

i had some troubles starting with my desktop graphics, so I reinstalled gdm3 and then ubuntu-desktop again. Something went wrong on the networking on the way.
- When Ubuntu loads there is no networking icon at the top right
- Network is not connected.

I can connect manually using `ifconfig enp2s0 up` followed by `dhclient -r enp2s0` and `dhclient -r enp2s0` (as done here https://askubuntu.com/questions/1025...-but-ipv4-isnt)
This is working, but I need to do it again after each reboot. How I set it to automatically connect after reboot?

I also tried setting `managed=true` in the NetworkManager.conf but it had no apparent effect.

thanks

Live Lubuntu 20.04 don’t connect mobile internet

While trying live Lubuntu 20.04.1 on my old desktop it has been impossible to get connected to the internet with my usb dongle, that has always been working without problems from live systems, I use both Xubuntu and Lubuntu, and indeed I did try with Xubuntu 20.04 live dvd also, and connects without problems.

When I open the drop down menu in Lubuntu live system, it recognize and correctly list my ethernet connection; when I create a new connection with the mobile internet menu in Network Manager, it looks fine, but when trying to connect there is no visible action.


Also, the textbox for the password keeps erasing: when I click save and then re-open the connection settings, it is gone, while all the other settings are saved correctly.

The ethernet connection seems to work, at least it connects to my old Belkin-g router.

Right-click show networking and Wi-Fi enabled, even if I don’t have any wi-fi adapter.


Computer is a gigabyte m770, athlon II 245.
Internet dongle is ZTE WCDMA Technologies MSM MF110/MF627/MF636 [ per lsusb ]

Is it even possible to solve it, or does anybody at least know the reason why all Xubuntus and previous Lubuntus works, and this latest one not, thank you anyway.

Hey everyone, I'm working with a HP Stream that will not connect to wi-fi.

When I reboot the computer, the wifi is available for me to connect to, but once I connect it shows connected for a second then it shows "Activation of network connection failed."

Please let me know if you need more info. Thanks.

[ubuntu] Wireless network connecting for only 5 minutes then destination host unreachable

September 20, 2020, 5:13 am

My wireless network is detected and connects with Internet access for only 5-10 minutes. After that Internet connection is lost even though the wireless network remains connected. At this point ping 8.8.8.8 returns "Destination Host Unreachable" and the only way to re-establish the connection for another 5 minutes is to restart the network. This cycle of disconnection continues indefinitely. Over the past 4 weeks I have tried
(1) reinstalling the ath9k driver using modprobe
(2) running dpkg-reconfigure resolvconf
(3) disabling IPv6
(4) disabling WiFi power save mode
(5) pinging the router continuously
(6) changing router settings from auto to channel 11, 2MHz
The router is a 5G Huawei box which is configured to split into 5GHz and 2GHz networks. The laptop is dual boot Ubuntu 16.04LTS and Windows 10 (the network works fine in Windows 10). Is this a DNS issue? How can this be fixed?

[kubuntu] fstab no longer mounting nfs shares at boot

September 20, 2020, 11:04 am
$

After years of arm-wrestling with samba, I finally gave up and gave NFS a try, which I think is superior in a pure Linux network like I have now.

The problem is, the shares won't mount at boot, even though they're defined in fstab.

if I wait until the system is done booting, I can execute
Code:
sudo mount -a
and the shares from the server mount perfectly. My question is, why won't this work at boot time?

Here's what their lines look like in fstab:

192.168.1.2:/media/Romulus/Television /media/Television nfs defaults,timeo=30,retry=10,auto 0 0
192.168.1.2:/media/Kronos/Movies /media/Movies nfs defaults,timeo=30,retry=10,auto 0 0

And like I said, they mount just fine if I do it manually with mount -a, but they won't mount at boot. It's like systemd is just ignoring the entries. All of my internet searches lead me to results that discuss using systemd to mount them (with various methods that are a bit confusing) but I'd prefer to just keep things simple and do it in fstab like I mount my hard drives.

Any ideas of what I can do to make the system actually mount these at boot time? Is it because network manager isn't running yet? If so, is there something else I need to do to force that first?

[all variants] the best way to mount disk from device that is on wifi connection

Hi all,
Looking for the best way to mount disk from device that is on wifi connection.

Usually I just run mc file manager and connect it using ssh; I have shortcut in mc for this path and also authorize using ssh key, so it is more or less convenient. But as the device is on wifi connection, it can break in the middle of big file transfer and it doesn't allow to continue uploading, so I need to repeat it from scratch.

Now I'm trying sshfs and the connection also breaks, also uploading speed is extremely low, don't understand why.

Maybe there is another modern way to mount it, please advise.

[ubuntu] No DNS after static IP change on Ubuntu Server 16.04

I recently signed up with a new ISP who gave me a new router and without changing too much on their router I thought I'd rather update my servers IP address instead. It was a static IP address before and was working 100% but after the new static IP address domains don't want to resolve for some reason.
I am running a pi-hole server but not as a DHCP client, the router is still handling that. The routers DNS just points to the pi-hole.

The setup was working before the server IP change so I am not sure what I am missing now. Perhaps someone could shed some light?

/etc/network/interfaces file:

Code:
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

source /etc/network/interfaces.d/*

Not sure if this is relevant?

Bridged mode, security and router firewall

Hi, u just got my ssh server up and running by setting one port on my router to "Bridged Mode". As described in this post: https://ubuntuforums.org/showthread.php?t=2450506

What does "Bridged Mode" actually mean?
Because now i can connect over SSH to my ubuntu server using putty: ipadress:port without having a "Firewall rule" (Port Forwarding) in my router.

Does this have any affect on my security?

Tnx :):popcorn:

[kubuntu] KUbuntu 20.04 network questions on an UEFI system

I recently got a new laptop that came with Windows 10 and I wasted NO time getting that garbage off my system. As I expected, I had zero trouble installing KUbuntu 20.04, but since this new laptop does UEFI and I'm pretty unfamiliar with it, I'm wondering if the god-awful network device names that seem to have infested Linux in the last few years, one of the first things I do when setting up a new Ubuntu legacy system is the old /etc/default/grub "GRUB_CMDLINE_LINUX="net.ifnames=0 biosdevname=0"" and edit /etc/network/interfaces to the old tried-n-true eth0 and wlan0. My question is: Does this still work with UEFI? Want to be sure before I possibly screw up my new system... Did I mention I'm a newby re: UEFI... Not looking for
"get used to the new names" comments... Just WILL IT work or not?

Thanks

I have been able to connect to my VPN using their Pulse client but about 15 times a day it disconnects (and I find myself having to reboot to get the client working again).

In the Pulse log I see the error below .. does anyone know of a workaround or fix for Ubuntu? Apparently I cant use NetworkManager instead because it doesnt support the host checker.:

[ubuntu] Can't connect to ubuntu server

Good day. I have Ubuntu 18.04.2 LTS running my server. I have multiple Windows 10 PC's that need to access the server. I am using Bash on my PC to access and administer commands on the server via the network. My PC has no problem in accessing the server via Windows Explorer either.

Another PC had a factory reset done and since then it can no longer access the server. I can see the server via the network in Windows Explorer. However when I click on the server it says "Error code 0x80070035 The network path was not found". When clicking troubleshoot in Windows 10 it says it cannot identify the problem. The detailed information says that no issues are detected. This PC was previously able to access the server.

I have activated the SMB 1.0/cifs file sharing support feature on the Windows PC. In the windows command prompt I can successfully ping the IP of the server.

I have limited linux experience (server was setup by someone else). How can I get this machine to access the server again?

[ubuntu] Can't connect 5 GHz wlan with Ubuntu 16.04.7 LTS, Windows&Android works

Hello

When trying to connect on my Fujitsu Lifebook S761 with Ubuntu 16.04.7 LTS to wlan on 5 GHz channel (office_wlan 5 GHz) the system asks for wifi password. There is no password and my Android phone and a Windows laptop connect without it. I've tried with the password that is used in the Office_wlan without success. Does this have anything to do with Ubuntu wlan?


In the wireless-info I noticed following. Does this have to do with the problem?
Code:

once I saved the changes to fstab I test it with this -

..and the share is working.
However, when I reboot the share does not remount.

I have tried many variations with the options in fstab but no luck.

ASUS 1215p wifi keeps failing

Hi, I have this old trusty ASUS netbook, and haven't had any problems for years, but just recently the wifi stops working, usually if you are not on the machine for a while and then I have found no way of getting it going again other than a hard restart.

I was previously using Ubuntu studio 18.04, but I just installed Lubuntu 20.04, hoping that the problem would be fixed by re-installing, however the problem persists.

Could it be that there has been a kernel upgrade, and the wifi module doesn't like it? Previously the bluetooth would never work, but it started working a couple of months ago, maybe due to an update.

Any help would be appreciated.

Cheers,

Sam

Is is possible to restart GlobalProtect GUI via CLI?

Not sure if this is the right forum, pointers welcome. Tag suggestions welcome.
I am using a VPN with Palo Alto Networks and GlobalProtect. Ubuntu 18.04.
When I login I am prompted to sign in via Okta before clicking 'connect' on the small GlobalConnect Gui. This works and I am able to connect.
However, if I have been logged out for a while, e.g. overnight, then when logging back in I get an endless 'connecting' message on the Gui and am unable to connect. If I restart, all works fine.
To save me from restarting I wondered if there was a way to restart the GlobalConnect Gui from the terminal?
I posted the same on reddit here. I was told to try the following:
Code:
`sudo systemctl restart gpd.service`
Outcome: I lost the vpn connection and in the upper right app GlobalProtect tool like in the screen, it still says 'connected'. I tried pressing 'disconnect' and now I have an indefinite 'disconnecting' message!
I then tried:
Code:
globalprotect disconnect
Outcome:
Code:
   
globalprotect disconnect
Cannot parse your input.
The valid CLI commands that you can now use are:collect-logimport-certificatelaunch-ui
Is there a way I can restart the Global Protect gui from the command line?
