On laptop wakeup I see a process called ip that uses 100% CPU. It won't stop on its own, I need to manually kill it every time.By looking for it in ps I could find that the command being run is ip route show.When I run it manually, the command also doesn't terminate and prints the same few lines over and over again:

EDIT: the issue seems to disappear when I turn off my vpn

Ubuntu 19.10, Dell XPS-15-9570, kernel 5.3.0-41

This is really affecting my battery life. Anyone has experienced a similar issue or know how to fix it?

I have a problem with Huawei E3372 modem.

Xubuntu 18.04.2 LTS did not detect it as a mobile broadband modem. E3372 is not detected.

I have checked lsusb, and here I can see the system detects it as 12d1:1506 Huawei Technologies Co., Ltd. but I cannot choose it in my Network Connections.It displays Mobile Broadband not enabled.

I have added

Huawei E3372

ATTR{idVendor}=="12d1", ATTR{idProduct}=="1506", RUN +="usb_modeswitch '%b/%k'"

in /lib/udev/rules.d/40-usb_modeswitch.rules.

I followed the steps in the posts

Huawei E3272 UbuntuandHuawei usb 4G modem not detected

but in vain

configPack.tar.gz does not contain 12d1:1506. hence the following command

tar xf /usr/share/usb_modeswitch/configPack.tar.gz 12d1\:1506

didn't worked. Hence I followed the same code in the post

tar xf /usr/share/usb_modeswitch/configPack.tar.gz 12d1\:14fe

and went to the folder /usr/share/usb_modeswitch/

cp 12d1:14fe 12d1:1506

and added the line in the following file

add line to file /lib/udev/rules.d/40-usb_modeswitch.rules:

ATTR{idVendor}=="12d1", ATTR{idProduct}=="1506", RUN+="usb_modeswitch '/%k'"

Still it didn't work.

Again tried, added the following to the file /lib/udev/rules.d/77-mm-usb-device-blacklist.rules:

ATTRS{idVendor}=="12d1", ATTRS{idProduct}=="14fe", ENV{ID_MM_DEVICE_IGNORE}="1"

Nothing worked so far.

Your help is much appreciated.Thanks in advance.

I can't connect Bluetooth devices on Ubuntu 19.04. My USB Bluetooth dongle is Cambridge Silicon Radio, Ltd Bluetooth Dongle (HCI mode).

Last evening I made the requested packages upgrade for Ubuntu 18.04.4 Desktop. But now I'm not able to connect to the network anymore with the previous network configuration files.These are the packages upgraded:

Here's the NetworkManager.conf file content:

$ sudo nano /etc/NetworkManager/NetworkManager.conf[main]plugins=ifupdown,keyfile[ifupdown]managed=false[device]wifi.scan-rand-mac-address=no     

Following these indications: No wired connection - Wired unmanaged ubuntu 18.04

I tried to put managed=true in /etc/NetworkManager/NetworkManager.confand run

sudo service network-manager restart

followed by a system reboot.
But the problem still persists.

Modifying the 01-network-manager-all.yaml file:

$ sudo nano /etc/netplan/01-network-manager-all.yaml#Let NetworkManager manage all devices on this systemnetwork:  version: 2  #renderer: networkd  ethernets:    enp3s0:      dhcp4: no      addresses: [192.168.1.7/24]      gateway4: 192.168.1.1      nameservers:        addresses: [8.8.8.8, 8.8.4.4]

to

made the wired connection working again.

What happened due to this Ubuntu 18.04 package upgrade?

Some time ago, I tried to change my DNS in Ubuntu 18.04 and ended messing up some system files.

Every website I tried to connect to would give me the message "DNS_Probe_Error".

After some time googling, I found I was able to fix it by executing this in terminal:

sudo ip route add default via 192.168.25.1, where the ip is my router address.

The thing is, I have to run this same command every time I reboot.

How to I permanently set it?

I run Ubuntu Budgie 19.10 on an Intel based pc, dedicated as NAS. This system runs PiHole as a docker container, and within Docker, a macvlan has been created to make sure the PiHole docker receives its own dedicated IP address from the router. This all works fine.

In order to reach the PiHole webinterface from the host PC (I can already access it from any other device in my LAN), I need to create a macvlan bridge on the host PC:

ip link add mynet-shim link eno1 type macvlan  mode bridgeip addr add 192.168.88.10/24 dev mynet-shimip link set mynet-shim upip route add 192.168.88.5 dev mynet-shim

This works fine, after running these commands, I can access my PiHole (192.168.88.5/admin) webUI via the hostPC itself (192.168.88.10). Note I don't understand these commands, or macvlan, I just search the internet and try to understand as much as possible. Lots of trial and error :)

However, after a reboot, this macvlan bridge is gone. How do I make it persistent?I understand I might have to create a file /etc/network/interfaces, but I will be forced to define ALL interfaces there.. not just this thing I created manually, also virtual or real interfaces that are created automatically. I am not sure if I am capable of that.

What would be the best way to figure this out?

i am using a Raspberry PI as a VPN network gateway to route all my traffic into it.so on the PI i want to set up a docker container.The appliations in the docker container should not route through the vpn tunnel.So can i use a network bridge to assign a IP address from the local DHCP server wich provide another default route ?I see there is an option called --net host Or what should i do ?

Thanks

I a Broadcom 4312 using the STA drivers, I reinstalled ubuntu because the b43 drivers were giving me a huge hassle along with some weird kernel issues.

My wireless speed is fine, everything works well, except upon restart of computer and after taking the computer out of suspend. It takes about 30-45 seconds for the wireless to reconnect, and I think it is a driver issue (I clicked on the network manager at the top and for about 30 seconds there are no wireless networks listed.)

I tried this advice already: http://lilserenity.wordpress.com/2007/10/31/fix-ubuntu-dropping-wireless-on-suspendhibernate-resume/which basically says to change this:

STOP_SERVICES=""

to

STOP_SERVICES="networking"

in the file

/etc/default/acpi-support

This did not help anything. Something to note is that the issue does not occur when I am logging back in after already logging in once and logging out.

Often when using Firefox 73.0.1 in Xubuntu 18.04 to browse a web forum about a retrocomputing hobby,* I see 30-minute periods when all connections to that website time out but connections to other websites and non-web Internet resources continue to work. Checking through the website "Down for Everyone or Just Me?" during such an outage shows that the outage affects only me, as does asking other users on a Discord server and an IRC channel related to the website's subject matter.

Comparison of a traceroute to the server during both working and outage periods shows that my packet stops just as it leaves Cogent's network. I have evidence (from a source that I cannot disclose publicly) that the first IPv4 address after the packet leaves Cogent is the IP address of a firewall that sees a bunch of SYNs (the first packet in a TCP outgoing connection) from my IP address and blocks my home Internet connection's IP address as a measure against denial of service (DoS).

I managed to capture getting blocked using Wireshark on my laptop's WLAN interface. (It has no wired Ethernet interface.) The packet log shows 19 SYN packets from my laptop for the first page view and 17 for the second, each with a different ephemeral port, most of which it immediately closes with RST. This burst of 36 SYNs in 4 seconds appears consistent with what my source told me.

So I want to limit Firefox's rate of connection to that site and only that site. Turning off these settings in about:config did not help:

• network.http.speculative-parallel-limit
• network.prefetch-next

Others have suggested reducing network.http.max-persistent-connections-per-server, but I hesitate to reduce this because it would slow access to all other websites as well. Is there a way to keep Firefox from being too eager to connect to websites under a particular domain name while behaving as usual for other websites?

^{* I hesitate to name the website for fear of appearing to unduly promote it.}

Problem

My computer randomly freezes (does not accept any input anymore, mouse pointer is frozen) or shuts down (not completely, it "hangs" so that even pushing the reset button won't restart, I then have to press the power button for a few seconds to turn it off completely).

System

Hardware

I'm using a wifi USB stick to connect to a wifi repeater, which in turn connects to a wifi router that is connected to the internet. My wifi stick is old and there are no official Linux drivers so I'm using ndiswrapper to load Windows drivers. The DHCP sits on the wifi router.

Software

I'm running KDE Neon which is based on Ubuntu. I'm new to the Linux world, forgive me if this is missing vital information. I'm using UFW firewall and connect to VPN servers through openvpn, using the NetworkManager package. I checked the syslogs for a recurring pattern before the system crashes.

I'm not 100% sure about these rules but the intent is to block any traffic that isn't going through the vpn tunnel (tun1, tun0) and to specific IPs of my VPN service provider. It seems to work that if the VPN connection stops working no other traffic is possible. The 224.0.0.1 rule is there because I've read this is some signal coming from the repeater potentially causing problems, but it seems to have no effect.

Thoughts

I have a hunch the crashes are related to network issues. They seemed to have increased since the hardware setup was changed to incorporate the wifi repeater and/or since I've set up those VPN-related firewall rules.

NetworkManager[1184]: <info> [1581604961.4136] connectivity: (wlxb039564f2855) timed out seems to happen often before freezes. And freezes occur dis-proportionally often after the computer has been idling for a while.

Any help is much appreciated!

After many months without problems, the wifi on my ASUS Rog Strix stopped working. It's possible that it was broken after I mistakenly did sudo chmod -R g+w /. ... anyway...

In Software & Updates I now get this:

Here's what I can tell from the terminal:

sudo modprobe iwlwifi returns no output

The sad thing is that if I run an Ubuntu Live USB, wifi works perfectly there.

Is it possible to fix this besides reinstalling Ubuntu? Reinstall wifi drivers are something similar?

Edit: I have downloaded the latest lib/firmware file from Intel's website iwlwifi-9000-pu-b0-jf-b0-34.ucode, but it hasn't helped.

I'm running 18.04. My Sonic wifi is constantly dropping. Eventually, it seems to come back of it's own accord, but since this is unpredictable, I often resort in the meantime to a bluetooth connection from my phone. Once bluetooth is connected, the output from ifconfig seems to be identical, whether or not I have a Sonic wireless connection, specifically:

Obviously, I want to turn off bluetooth as soon the Sonic connection comes back up. But since ifconfig gives me no useful information, is there some other output I can condition on? As a followup question, why does ifconfig wlp59s0 give me this false positive feedback, when in fact I do not have a wifi connection, i.e., if I turn off bluetooth I have nothing? Thanks for any suggestions!

I can scan from my WF-2830 all-in-one. I have installed the imagescan-bundle-ubuntu-18.04-3.62.0.x64.deb driver from the Epson website. I edited the /etc/imagescan/imagescan.conf as follows:

myscanner.udi = esci:networkscan://10.0.0.206:1865

myscanner.vendor = Epson

myscanner.model = WF-2830

After selecting the above esci scanner from xsane's list, it accesses the scanner but gives, "Failed to set value of option x-resolution: Invalid argument," and "Failed to set value of option y-resolution: Invalid argument" when acquiring a preview.. However, after closing the error windows, it does deliver a preview image and a scanned (with xsane's scan button) image. Why the error messages? How do I get rid of them? Should it concern me that I receive them at all? Should I report a bug to Ubuntu or Xsane?

Searching the files listed by dpkg -L imagescan does not find any files containing x-resolution or y-resolution.

I'm a brand new Ubuntu user. Installed it on a new HP 14-dk0024. I'm getting "No Wi-Fi Adapter Found" and have been looking for solutions. I have disabled secure boot. I'm new to using a terminal and have tried some of the previously stated solutions but haven't had success. Are there updated drivers that I can install and how do I do that. Thank you!

I'm setting up an ubuntu embedded system as a "master" server which will then broadcast to clients using ad-hoc in a wlan. The purpose is for a client to access the wlan and then access a webapp on my local network.

But instead of having then going to my ip address or my hostname.local i want then to be redirected from all requests to the my hostname.local address in order for them to only access my webapp and nothing else.

Searching on the forum, I found dnsmasq although I'm not sure if this would work for me seeing as I need all requests * to be redirected.

Any ideas? Regards

I am new to Ubuntu and I know there were a lot of similar issues and I've tried to follow some of the answers on the web (e.g. Dell Inspiron Wifi off or How do I get an Atheros AR8162 working?), but none of them are working, or are causing more errors along the way.

Recently I bought new Dell Inspiron 15 with installed Ubuntu 12.04 on it, but there are no options were to connect to wifi. My router is working and all other devices are seeing it.

Here is some information that you might need for advice. I'll be happy to provide anything further, please help me.

Using these helped

`sudo apt-get install linux-backports-modules-cw-3.10-precise-generic sudo modprobe ath9k `

but not for a long time.Then I tried this advice and wifi works again:

Can't reach wi-fi signal on Ubuntu, but can do it on other OS/devices (ath9k)

I have a Dell inspiron 17 and I installed Ubuntu yesterday and when I logged in (I was originally on windows 8) there were no WiFi connections at all...

I've tried everything and I can't seem to find a solution...

I'm relatively inexperienced with Linux but I've spent the past 48 hours trying every solution I could find to this problem to no avail, I even tried a full system wipe and reinstall with no luck. After upgrading to Ubuntu 18.04 my system no longer sees any wifi networks. This is happening to my external usb adapter as well despite all the drivers being in place for it and having used before on previous versions.

lshw -C network gives me this:

Let me know what other information I can give or diagnostic commands I can run to assist any diagnosis. I'm very much at the end of my tether on this one so any assistance would be very much appreciated.Thanks

I accessed Windows 7 Shared Files through the Files System in Ubuntu 16.04 and it worked fine.But, when I tried again, I can't access Windows Shared Files anymore. I have a message like:Failed to recover server shared list - Folder or File not Found (I am translated from portuguese, and maybe it's not the popup in English).

• In cmd I tried smbclient -L TDMS-PC -U TDMS I get "Error NT_STATUS_UNSUCCESSFUL"

• When I ping, I can reach the windows machine and vice versa

• Both Machines have the same network masks

• When I tried smbclient //192.168.1.23/downloads -U TDMS I get "protocol negotiation failed: ERRDOS:ERRnomem"

And it worked before (in the Files Manager).

What could be wrong?

I have a script that is run when a server (Ubuntu 14.04) boots up using @reboot in crontab (Under the root user)

@reboot /bin/bash /root/init.sh >> /var/logs/vminit.log

The script runs a number of things, but when it reaches this line

ifdown eth1

The script exits, and ifdown does not run. (Running ifconfig still shows eth1 in the output) Enabling Verbose mode on ifdown returns nothing too.

If I manually run the script myself, it runs as expected.

I wrote a test script just to rule out any issues with init.sh

#!/bin/bashecho 'one'ifdown eth1echo 'two'

If I run it manually, I get this output (which is expected)

one<DHCP Client info>two

If I place this test script into the crontab to be run with @reboot, I get the same results as init.sh, and the output is

one

I've tested by running the cron at an exact time (Example: 25 14 * * *) to see if it's something with `@reboot', but no luck.

I've also tried delaying the script from running after boot incase something was blocking ifdown from running

@reboot /bin/sleep 60; /bin/bash /root/init.sh >> /var/log/vminit.log

A few notes: - Eth1 is an active interface, prior to running ifdown the script makes a call out of eth1 to grab a file successfully.- The script is run as root- Permissions with the script (and log) are fine. - Running init.sh or the test script manually runs as expected.
