≪ Previous: Our router doesn't want us to video chat

hey guys, yesterday installed new ubuntu 20.04 into empty SSD. Works fine, just have a problems with connecting to ssh (servers, switches).
Unable to negotiate with xxx.xxx.xxx.xxx port 22: no matching key exchange method found. Their offer: diffie-hellman-group-exchange-sha1,diffie-hellman-group14-sha1,diffie-hellman-group1-sha1

already added this in ~/.ssh/config
Host abcdef
HostName xxx.xxx.xxx.xxx
User myusername
KexAlgorithms diffie-hellman-group-exchange-sha1,diffie-hellman-group1-sha1

it works fine now. But is there any way to connect to ssh without using ~/.ssh/config?

Tried to add it into /etc/ssh/ssh_config - ciphers, didn't help it.
We have about 300 switches, don't want to add every switch into ~/.ssh/config.
ssh worked fine with ubuntu 18.04

Thank you for any help.

[ubuntu] No wireless icon Ubuntu 18.04

≪ Previous: [ubuntu] Ubuntu 20.04 - Unable to negotiate ... no matching key exchange method found

I was running version 16.04 and decided to update to version 18.04. After it was installed I ran update and upgrade, everything worked great. I rebooted and could not find the wireless icon, to enter my code. I have tried many solutions that I have found on line, but nothing works. The last one I found online was this one and tried it. It was from chili555

*****Sorry, I do not remember what to post before and after a terminal post to make it scroll in a small box.*****

A newer version of iwlwifi can be installed that includes your device and, crucially, the exact subsystem. With a working internet connection by ethernet, tethering or whatever means possible, open a terminal and do:

sudo apt update
sudo apt install git build-essential
git clone https://git.kernel.org/pub/scm/linux...rt-iwlwifi.git
cd backport-iwlwifi/
make defconfig-iwlwifi-public

sudo make install
sudo modprobe iwlwifi
I am not certain that the firmware is included in the latest version of linux-firmware. If your device doesn't start working immediately, check the log for messages and we'll then address the firmware if it's missing.

[kubuntu] Etherenet connection not restablished after suspend

April 24, 2020, 11:00 pm

≫ Next: lubuntu 19.04 Bluetooth troubleshooting guide

≪ Previous: [ubuntu] No wireless icon Ubuntu 18.04

This has actually been an issue since some point in the 16.04 life cycle, initially 16.04 did not have this problem. I stopped being able to connect to the wired network connection after suspending. I assumed I installed something to break it but I've recently played with a few Ubuntu variants (Pop!_OS, Elementary, Ubuntu, Kubutnu) all the latest stable versions over the last month or so and the problem is persisting. There are certainly some type of logs that would provide hardware info but I'm going to need a bit of help figuring that out. I suspect it is an issue with my specific hardware.

I just installed 20.04 Kubutnu. A hardware list as a start:

Hello guys,

Is there a troubleshooting guide based on cmdline for bluetooth issues? I have no clue where to start for my Latitude 7370. How do I know if the drivers are even loaded? Thanks.

Hi all,
Can't understand what is going on.
ifconfig returns only 'lo' on my PC. No ethernet and wifi card available. I'm writing this from my notebook where everything is ok so far.

I ran apt-get update; apt-get upgrade on my PC recently (and did not do it on my notebook for a while), is it something that could possibly cause this issue?

I can use my usb modem on PC though, virtual network card appears in ifconfig after I plug it.

18.04.4 LTS on my both computers.

Please help.

≪ Previous: [all variants] help! no network devices but 'lo' on my PC

I installed Kubuntu on a separate partition WITH active WiFi connection to try it out, but now suddenly, I can't get online. :confused:

I booted from a DVD into Live Mode with Internet connected and then installed Kubuntu 19.10. Everything went smoothly. Now I'm trying to set everything up. The WiFi icon is in the tray and shows me as Connected to my WiFi network. But when I open Firefox or try to install any updates, I can't pull anything up. If I click on the WiFi tray icon, it shows upload activity but d/l activity is at 0mb.

This makes no sense. How can I be connected to my WiFi network yet not have an Internet connection (after having just installed Kubuntu with an Internet connection?)

What am I doing wrong? How do I fix this? TIA

PS: I noticed that I HAVE a working WiFi connection when Kubuntu starts, but just a few minutes later (sometimes only a minute, sometimes longer), I can no longer see other networks and my own connection becomes inaccessible. (Details: a USB-2.0 WiFi adapter. My personal network is named "Virus Central" to scare away intruders. :P)

Hello

I have a problem with the following topology:

Topology 1: computer with Lubuntu 18.04/phone ->Wifi->router2(192.168.1.2) with Open network authentication->Ethernet->router1(192.168.1.1) with WPA2->Internet

router2's DHCP is disabled
router1's DCHP is enabled in this range: 192.168.1.5-192.168.1.254
computer's IP is static: 192.168.1.10

The content of /etc/netplan/01-netcfg.yaml in the computer is as follows:

Quote:

# This file describes the network interfaces available on your system
# For more information, see netplan(5).
network:
version: 2
renderer: networkd
ethernets:
ens33:
dhcp4: no
addresses: [192.168.1.10/24]
gateway4: 192.168.1.1
nameservers:
addresses: [8.8.8.8, 1.1.1.1]

I am trying to get a wireless connection to router2 from a computer or a phone in order to get online but for some strange reason I do not always get connected, only a few random times.

Nonetheless the following topology with the same computer and just replacing the Wifi connection between computer and router2 for the Ethernet connection works always like a charm to let me go online.

Topology 2: computer ->Ethernet->router2->Ethernet->router1->Internet

I guess out of the previous information it can be inferred that the problem might be at the wireless connection between router2 and computer/phone. I would like to be able to get online wirelessly from computer or phone though.

Router2 is AR-5387un COMTREND. I do not know how to set 192.168.1.1 as local gateway IP within router2's administration console. May be I need to fix that.

Right now one of the phone that I have with me connects without problem but other phones do not connect. Anyway this phone had problems to connect 2 hours ago.

Another interesting thing I saw: one hour ago the computer got connected to router2 wirelessly. Then I disconnected and connnected it to router2 several times as a test and it kept on connecting well. But then I did another test: I connected the computer to router1 wirelessly and then I tried to connected it once again to router2 wirelessly and then the problems came back. Since then the computer did not connect wirelessly to router2 any other time.

When the computer does not get online

Quote:

ping 192.168.1.1

from the computer displays the following

Quote:

connect: La red es inaccesible

I also just checked that the problem gets temporarily solved right away, ONLY for the computer, by restarting router1. But in case I change the wifi connection from router2's wifi interface to the router1's wifi interface and back to router2's wifi interface, then the problem arises again to get online on router2's wifi interface. Restarting router1 does NOT help with phones wifi connection to router2 at least right away like in the case of the computer. But is somehow strange because at some point may be 5 minutes or 10 minutes after getting online in the computer, one of the phones also ends up getting a local WLAN IP address and getting online successfully as well. And once this phone gets connected, I can disconnect it and connect it again to router2's wifi interface wirelessly without a problem unless I connect it in between to router1's wifi interface. Then getting back to router2's wifi interface will bring the problem back again.

I guess all the devices might be struggling to get a local IP address and that is why they have a difficult time getting online wirelessly but I do not know why.

Among other lines

Does anyone have any idea about how I could fix the Wifi connection so that it stops having this random behaviour?

Thanks in advance.

So im running Ubuntu 19.10 on a Dell Studio with 4GB ram and dual 2.8GHz with like 3 hard drives (basic, do it all server) then connects to google wifi router over powerline Ethernet. It runs a dummy monitor at 1360x768 and runs RealVNC. but then in my bedroom ive got a raspberry pi zero w with raspbian connected over wifi. I use RealVNC, but it tends to lag sometime, no audio, and video playback is basically non-existant. Does anyone have any suggestions? id rather find some software solution than a hard ware solution.

[server] USB modem installation

Hello All,
I am new to this forum. I am new to any forum at all.
I know that this topic was discussed many times but I could not find a relevant thread or the information is missing.

I have a USB modem - the most popular - Huawei E3372 and it works great on a desktop installation of my new ubuntu 20.4 but... it does not work on the ubunto 20.4 server instance. I have no idea what is the matter.

Here below is the output from syslog on the server:

WoL not working

≪ Previous: SSH - First time connecting to a computer

Hi guys,

First post, long time reader of the forum to help solving my problems, needing your support this time.

I am successfully powering on my home made Ubuntu Server 18.04 NAS1 from my PC1 Linux Mint 19.2 Build (Ubuntu 18.04 based).
Both have their IP addresses reserved in my router according to their MAC Addresses and are on the same subnet.
When NAS1 has been shut down (with sudo shutdown - h now), I can turn it on from PC1 by sending wake-on-lan (WoL) magic packets to it either with the powerwake or wakeonlan command.

I showed this to a friend and it ended up with him wanting the same solution, so I made him one similar Ubuntu Server 18.04 build, let's call it NAS2.
As you may guess, NAS2 is not responding to WoL, no way to power it on remotely. :(

NAS1 and NAS2 components are very similar, and both are based on the very same motherboard, an Asrock J3455-ITX.
One difference though is that NAS1 has got an 1.40 UEFI version while NAS2 is on a 1.60 UEFI version.
Both have the following UEFI setup that, to my understanding, should enable WoL:

Code:

Onboard LAN            :  Enabled

Deep S5                :  Disabled

PCIE Devices Power On  :  Enabled

Boot From Onboard LAN  :  Enabled

Secure Boot            :  Disabled

For NAS2, here is what $ sudo dmidecode | less shows me for the network card:

Code:

# dmidecode 3.1

Getting SMBIOS data from sysfs.

SMBIOS 3.0.0 present.

Table at 0x6DC50000.



Handle 0x0009, DMI type 9, 17 bytes

System Slot Information

        Designation: mPCIE

        Type: x1 PCI Express

        Current Usage: Available

                3.3 V is provided

                Opening is shared

                PME signal is supported*

        Bus Address: 0000:ff:1f.7

*Power Management Events, which include WOL

For your information, other NAS2 parts are:
- Kingston Value RAM 8GB, DDR3L-1600, SODIMM 204 (KVR16LS11/8 which is on the memory compatible list of the Asrock J3455-ITX)
- Micron SSD - 256GB

On the NAS2 itself, the enp1s0 network controller is set for DHCP, $ nano /etc/netplan/01-netcfg.yaml:

Code:

# This file describes the network interfaces available on your system

# For more information, see netplan(5).

network:

  version: 2

  renderer: networkd

  ethernets:

    enp1s0:

      dhcp4: yes

That's it for the system I think, if you need some more info please let me know.

With NAS2 turned on, I am able to check for incoming packets using ngrep or netcat, when sending Magic Packets from PC1 with $ wakeonlan a1:b2:c3:d4:44:12.
For instance with netcat $ sudo nc -ul -p 9, I get:

Code:

Some binary code

Or with ngrep $ sudo ngrep '\xff{6}(.{6})\1{15}' -x port 9, I get:

Code:

interface: enp1s0 (192.168.1.0/255.255.255.0)

filter: ( port 9 ) and ((ip || ip6) || (vlan && (ip || ip6)))

match: \xff{6}(.{6})\1{15}

  a1 b2 c3 d4 44 12                                    p...D.

Strangely, I get nothing when trying to send packets with $ powerwake a1b2c3d44412.
However I experience exactly the same with my working NAS1, even though a wakeonlan or powerwake command is able to power it on.

And I don't know if that indicates something, but with $ sudo etherwake a1:b2:c3:d4:44:12 -i enp1s0, I see this (on both NAS though):

Code:

SIOCGIFHWADDR on enp1s0 failed: No such device

So finally, as said above after shutting it down with $ sudo shutdown -h now, impossible to turn it back on either with $ wakeonlan a1:b2:c3:d4:44:12 or with $ powerwake a1b2c3d44412.
And this even though the results of the above tests seem to point to an available WoL functionnality.

Am I missing something?
Are there other tools that could help me point out where the problem is?

Lastly, I tried to change the OS to Ubuntu 18.04 Desktop, Linux Mint 19.3, and I even tried to clone the NAS1 OS SSD to check it on NAS2. But all attempts to power on the build with WoL failed.
Which makes me think, especially because of the cloned SSD, that the problem comes from the UEFI of NAS2, or an hardware problem on this motherboard.

I am very interested in seeing what you think about all this!
Thanks for reading, I was rather long!

[ubuntu] No more smb access after migration to UBUNTU 20.04 from UBUNTU 19.10

April 27, 2020, 5:13 am

≫ Next: [ubuntu] 20.04 wifi

≪ Previous: WoL not working

Hello everyone,
I no longer have access to my devices (NAS and other pcs - windows) from Nautilus. The command smb://IP address doesn't work anymore since the upgrade.

I tried to change the parameter "client max protocol = NT1" in client max protocol = NT1 since my NAS is still in smb1 version. But without change, I can't navigate the network using smb, but I can do it with AFP.
I don't know if this will be useful but I also added "/usr/lib/x86_64-linux-gnu/gnome-vfs-2.0/moduleslibsmb.so" and modified
"/etc/gnome-vfs-2.0/modules/extra-modules.conf" to account for smb in nautilus. I can browse the Windows network again, but I can't access my files, just the share folder.
To get around the problem I went through an fstab mount, it works but it's less convenient and the login is slower.
Hopefully someone will be able to help me.

is Broadcom Wi-Fi an issue in 20.04 release? (Unusual error message...)

April 27, 2020, 9:52 am

≫ Next: Network working, but Ubuntu thinks I'm not connected

≪ Previous: [ubuntu] 20.04 wifi

Background: I had issues with the Broadcom Wi-Fi in my Dell Inspiron 1545 laptop previously. They were fixed by downloading some firmware. (More specifics in this thread. )

I am currently running Lubuntu 17.10, and when I upgraded from 15 to 17, I had no issues that required re-installing Broadcom Wi-Fi firmware per the linked thread above. Somewhere I read that in 17.10 the Broadcom wireless was not an issue any more, although I don't know where I was told that.

Now, I want to install Lubuntu 20.04.

I have put the .iso on a USB stick and booted 20.04 several times. Each time, I get different messages on boot or shut down. Most recently, I got several lines starting with the following:

Quote:

[ 97.605515] b43-phy0 ERROR: Firmware file b43/ucode15.fw not found.

So, b43 means an issue with the Broadcom, right?. However, I am not sure what's going on. The problem is that if I install 20.04 and lose Wi-Fi afterwards, I may be screwed.

Does the error message mean I actually lost that "ucode15.fw" file, or did the message occur only because I was booting from a USB (I have never done that before), meaning if I actually install 20.04, I won't have any issues with needing to install Broadcom b43 files again?

I have the USB stick that I used to fix the b43 issue last time. The ZIP and the command line commands I need are all on it. If I install 20.04 and my Wi-Fi doesn't work, can I use the same files and installation commands that I did last time to fix the issue, or does the new OS mean I need different files and/or commands to fix it?

I hope my problem is clear. Please help.

Network working, but Ubuntu thinks I'm not connected

≪ Previous: is Broadcom Wi-Fi an issue in 20.04 release? (Unusual error message...)

Ubuntu 20.04.

I'm trying to set up Online Accounts, but I'm unable to because it thinks I'm offline, despite networking being functional.

Clicking on the top right, it says "Wired Unmanaged" and I have the options of "Connect" and "Wired Settings". Connect doesn't do anything, and Wired Settings brings me to the Network Settings page.

Network is wired, no WiFi.

This is a fresh install, though originally installed from server image as I wanted to install to software raid.

Any ideas what's going on?

Thanks!

Trouble with WiFi on Ubuntu Server 20.04

≫ Next: RT5390R 802.11bgn unstable wifi, Ubuntu 20.04

≪ Previous: Network working, but Ubuntu thinks I'm not connected

Hi everyone!

So I installed Ubuntu Server on a laptop that I want to use for NextCloud. When I try to configure the WiFi, I lose all networking. I've tried configuring the default 00-installer-config.yaml and creating a file called 50-cloud-init.yaml. Here is the information that I'm inserting into the .yaml's:

network:
ethernets:
enp1s0:
dhcp4: true
version: 2
wifis:
wlp2s0:
addresses: [192.168.100/24]
gateway4: 192.168.1
nameservers:
addresses: [192.168.1, 8.8.4.4, 8.8.8.8]
access-points:
"*******":
password: "****************"

I've tried to .yaml validators and they say that I have the right spacing for my .yaml.

Does anyone have any suggestion as to where I'm messing up?

Thanks!

Hi,

I have just upgraded to 20.04 from 18.04, and I have a wifi problem: wifi starts ok after boot, but it is unstable, and I will eventually get the following message:
"Activation of Network Connection Failed"

I have found from an other thread a script to help the diagnostic: https://ubuntuforums.org/showthread.php?t=370108 (accessed from Jeremy21 signature)

Here are the results of running the script on my setup:

[ubuntu] Cisco AM10 wifi adapter not working on Ubuntu 20.04

≫ Next: (K)Ubuntu 20.04 completely ignoring VPN connection

≪ Previous: RT5390R 802.11bgn unstable wifi, Ubuntu 20.04

I booted up the liveUSB with Ubuntu 20.04 on my desktop with a Cisco AM10 USB wifi adapter plugged in. But looks like the wifi adapter is not detected.

Its weird since I previously had 18.04 running on this machine, and I was using this AM10 USB adapter. To confirm I also booted a liveUSB with 18.04.1 and it clearly detects the AM10 as a wifi adapter and is able to connect to my wireless network.

Anyone know if Ubuntu has removed support for this wifi adapter? Anyone any ideas?

(K)Ubuntu 20.04 completely ignoring VPN connection

≫ Next: Is the basic network monitor accurate?

≪ Previous: [ubuntu] Cisco AM10 wifi adapter not working on Ubuntu 20.04

I was wondering if someone might have run into the same issue as I have and/or have a solution to this problem.

When I start a VPN connection a Tun0 (OpenVPN) or 'wgivpn' (WireGuard, provided by IVPN) interface is enabled, yet internet-enabled programmes such as Firefox and Falkon completely ignore it, and use my regular connection instead: Google is displayed in my local language rather than that of the country I am connecting to, and can accurately tell me where my ISP is located.

I have tried both the IVPN CLI interface and the KDE networks GUI, with network-manager-openvpn installed. Wireguard, too, is installed.

This is a completely fresh Kubuntu 20.04 install - not an upgrade from 19.10, which I used previously. I've never run into this problem before, so I am not sure how to proceed.

Is the basic network monitor accurate?

≫ Next: [ubuntu] No wireless on Ubuntu 20.04 for Broadcom adapter

≪ Previous: (K)Ubuntu 20.04 completely ignoring VPN connection

Hello everyone,

How accurate is the basic network monitor in Ubuntu? I've recently upgraded my Internet connection plan from 6 Mbps to 75 Mbps (theoretical max speed of course), but the System Monitor has never indicated a download speed faster than around 750 kbps. I have a feeling that isn't correct based on testing it by watching HD videos.

All my wireless stuff is 802.11n, and I'm running Ubuntu 20.04.

Anyone have a recommendation for a better program to use, or maybe a setting I can change?

Thanks in advance!
