Hi all,

Host - Ubuntu 16.04
VM - Ubuntu 18.04
VirtualBox

VM can't ping domain but can ping IP address

$ ls -al /etc/resolv.conf
Code:
lrwxrwxrwx 1 root root 37 Oct 13 13:54 /etc/resolv.conf -> /run/systemd/resolve/stub-resolv.conf
$ cat /run/systemd/resolve/stub-resolv.conf
Code:
# This file is managed by man:systemd-resolved(8). Do not edit.
#
# This is a dynamic resolv.conf file for connecting local clients to the
# internal DNS stub resolver of systemd-resolved. This file lists all
# configured search domains.
#
# Run "systemd-resolve --status" to see details about the uplink DNS servers
# currently in use.
#
# Third party programs must not access this file directly, but only through the
# symlink at /etc/resolv.conf. To manage man:resolv.conf(5) in a different way,
# replace this symlink by a static file or a different symlink.
#
# See man:systemd-resolved.service(8) for details about the supported modes of
# operation for /etc/resolv.conf.

nameserver 127.0.0.53
$ cat /etc/network/interfaces
Code:

Several months before I encountered the same problem. Unfortunately I forgot the solution.

Please help. Thanks

[ubuntu] Bluetooth speaker sound distorted (ubuntu 18.04)

In a new laptop, the sound from my usual bt speaker (JBL Flip 3) is distorted: it can be ok for a few seconds but mainly it's crackling and interrupted intermittently.
Also the connection process is sometimes tricky... I have to connect/disconnect several times. The same speaker is working fine on another Ubuntu 16.04 laptop.

What I tried so far:

  • If I boot with Windows, it is ok
  • Within Ubuntu, another bt headset works fine
  • The good old trick of switching profile (A2DP/HFP) and then disconnect/reconnect doesn't solve
  • I've reinstalled pulseaudio and pulseaudio-module-bluetooth with no luck

Furthermore, my dmesg is full of:

Bluetooth: hci0: last event is not cmd complete (0x0f)

Apparently others are experiencing the same issues: Ubuntu 18.04 and bluetooth speaker JBL Charge 3

MHDDFS + Samba = writes take a while to start

October 14, 2018, 4:57 pm

Hello, I'm trying to diagnose a weird issue. I have several harddrives mounted over MHDDFS, and am sharing them individually (symbolic links in a directory that's shared) as well as in the combined pool.

Most things work fine over the network - writing and reading from the individual drives, and reading from the pool as well. However, writing to the pool has a weird issue: the larger the file, the longer transfers take to start, and they're not writing consistently once they've started, either. Files up to a few MB will insta-transfer, even a few dozen MB go quickly. But anything above takes at least some seconds to start the transfer, and with 1GB+ I'm waiting a while. (Addendum: writing to the pool locally seems to be fine and starts instantly. It's going through Samba and the network that's causing the issue.)

Samba's logs haven't been helpful, but I found out what mhddfs is doing while I'm waiting:
mhddfs [2018-10-15 01:03:37]: [140267440191232] mhdd_getxattr: path = /mnt/hd1/File-to-Copy.mkv name = security.capability bufsize = 0
This repeats many times, thousands if not more, before the file transfer starts.

However, I have no idea what it means. Anyone?

Resolving DNS problem on Wake/Running a script to refresh DNS on wake up

Hi all,

This is my first post in the Ubuntu forums although I've been a linux user for almost 16 years. I can run simple command line stuff and have no problems digging around in a system through terminal and making simple modifications. (In case anyone cares, I actually was on the Beta for Mac OS 10.0000; which is how I got involved in the linux community in the first place) Thing is I have an older macbook air 2011 model that can't do the gnome switch (not sure if it matters for the thread purpose).

In just the last month or two I noticed a slow down and problem loading web pages (in opera, firefox, and chrome). To be fair I do usually have lot's of queued tabs in multiple browsers and browsing apps running almost all the time. Then about a week ago I had to keep rebooting my computer after I closed the laptop in order to get the Internet working again.

The command I found that seems to alleviate this problem is : sudo systemctl restart NetworkManager

Works every time, just a little hiccup in reconnecting on Wake. Thing is I have to run it manually with an open terminal window every time right now.

I really don't have much experience setting a command like that to run properly on waking in the foreground or background. I could probably run the basic script in a simple "hello world" kinda script. I know it might need the user password for sudo, and that's where I'm stumped.

If anyone either can help create a simple automatic script to run the command that would be great. If anyone knows why the problem is happening or has any ideas as to how fix it more effectively that would be even better!

Windows shares are lost after several minutes

October 15, 2018, 6:44 am

Hi, I am working on an office environment which is all Windows based except for me.

The office has a Windows server that is shared among all persons in the office through Active Directory. I was able to set up my access through Samba long time ago, I initially had no issues, after a while (and probably a Windows Server update which I am not informed of) I lost connectivity and it resulted in me having to tweak my samba configuration to make sure it used SMB2 protocol (forced).

Now, the issue I have is that when I turn on my computer and I plug my ethernet cable to start my day it would open the share (through Gnome File Explorer), I am able to access everything, however, if I for example leave it opened and then lock my computer and get back, or if I simply don't open the sharing for a while, etc, it simply "loses" the connectivity. What I mean is if after I log in to my computer I don't immediately open the Windows share and use it, or if I open it but not actively use it for a while, when I try back it will simply fail and give me an error saying it has "An Unhandled Exception" and won't open it. I have to disconnect from the Ethernet and re-connect again in order for it to "remember" the network share and therefore work again. This makes no sense, because the server uses an internal IP of the 10.X.X.X type, so it is not changing IPs or anything.

This is kind of frustrating, I mean, it doesn't seem to be a configuration issue because it partially works, printers for example always work and they all are in the same network, it only will fail after a while. I haven't been able to find anything in the log files, in fact, I don't even know in which specific log file to look for as for samba logs it generates a log per each device you see online + generic logs, so I don't really know where to look and where I have looked there is nothing that gives me any hint.

I hope someone has had this issues and knows how to fix it, it seems to be something stupid but I can't find it.

[ubuntu] 2 factor authentication and remmina

Hello,

I am trying to connect to my companies network using duo 2fa and openforti. I have established the connection in openforti and have an active tunnel after receiving the push from duo. Now i want to use remmina to view the order entry system on the windows host.

My OS is Ubuntu 18.04 LTS

I cannot seem to get Remmina to connect. Do I need another push from duo to allow Remmina to connect? Do i need to install Duo on my Ubuntu Box?

Please let me know if I need additional information.

Any help is appreciated.

[ubuntu] cannot get network to function consistently

I continue to have problems with my connection. Right now settings and the icon top bar dropdowns tell me I am connected. I am not (cannot ping yahoo.com, etc). When its trying to connect settings will sometimes tell me that "status unknown (missing)". Sometimes I am connected and it just stops, even though it thinks its connected. To fix that I turn off the network and then turn it back on and, at least 70% of the time it won't connect. This is driving me nuts. I just did a complete re-install and that didn't help a bit.

I am going to put 2 files on pastbin. The first will be called netstuff. This is a copy of the results of some commands. Each one will tell the viewer if I am really connected or told I am connected whilst not being able to ping anything, etc. That file will be called "netstuff". I will also post a copy of my netstat file.

I don't know what else to do. Oh, It doesn't matter if I am using a wired or a wi-fi connection. The results are all the same, ie. network simply stops working whilst setting and icon dropdowns say I am, just stops working and says so, etc. This is true whether I have the vpn up or not. None of this makes any sense to me.

I have two network icons, one for the network and one for the vpn. The vpn icon remains solid, the network icon goes from solid to greyed out w/question mark, sometimes and other times greyed out with something on the lower right network block (there is one block connected to 2 others). I have also tried to test my netspeed with netspeed-cli as well as others on the net and they all failed to get the job done.

I had to turn off my wired connection and turn on my wi-fi connection to get this onto pastbin, I tried, several times, with both the wired and the wi-fi connection to upload my syslog and failed. Its 2mb long and it just craps out. so, I can only off the one below.

Ubuntu 18.04, Realtek RTL8188EE, Some websites load and some don't with Wifi

Hello all,

So my problem is with my laptop. Some websites load just fine (Google, Youtube, and facebook) and some don't (reddit, ubuntuforums, amazon, twitter) with Wifi.

Wired connect works just fine.

I've done
sudo apt update
sudo apt dist-upgrade

I tried using Chromium to see if it's the Firefox was the issue and that did not solve my problem.

I've also made sure that IvP4 and IvP6 are set to Automatic (DHCP) and Automatic respectively. Still have the problem.

Thanks in advance for the help.

[lubuntu] LAN connection not working but ethernet light is active

Hello,

I am trying to get an old computer (2006ish) to work again (installed windows 7 at first on it but the network drivers were only for xp and vista and i couldn't get them to work so i couldn't manage to establish a LAN connection).

Then, i've installed Lubuntu 18.04 32 bit on it because i know linux has better driver support, and even though the ethernet cable was connected during the OS installation and the light is still active, it cannot make a LAN connection.

I know the cable and the router are ok because when i plug it to my 2011 computer, it establishes a LAN connection instantly (automatic DHCP enabled). With the older computer, i have also tried adding an old network (neither the integrated card, neither this one have WIFI support, just wired) card just to see if the LAN would be working with it but it still doesn't even though the light works too when the cable is plugged in. I have experience with the linux command line but i never used it to fix a network issue so i'm quite lost, can you guys help please ?

Thank you

[all variants] Samba on Lubuntu 18 LTS not working with Xubuntu 16 LTS?

October 16, 2018, 7:42 pm

Hello all,

Not sure if the Ubuntu versions are a problem but basically I had Xubuntu and Lubuntu, both 16.04LTS running a LAN connection and Samba was fine; then I upgraded one machine to Lubuntu 18.04 LTS and Samba no longer wants to be recognized by the shares-admin in Lubuntu 18.04 LTS. When I try running the shares-admin it says I need to install samba or nfs; I tried installing samba with apt, both the server and client ( followed this answer -> https://askubuntu.com/questions/8839...-startup-error).

In the "Network Settings" app in Lubuntu 18.04 LTS there's a simple 3 tab layout with General, DNS, Hosts on top. I tried to enter the IP address of the Xubuntu 16.04 LTS machine along with the hostname and then rebooted both machines. After that I went into the network on the Lubuntu 18.04 LTS machine by using the file manager pcmanfm with the menu item go->network and that pops up an error saying "the specified location is not supported".

When it says "not supported", is this because the network implementation on the Xubuntu 16.04 LTS side isn't compatible to the Lubuntu 18.04 LTS side?

Basically Samba is dead on Lubuntu 18.04 LTS and the new network software in Lubuntu 18.04 LTS isn't compatible with Xubuntu 16.04 LTS? Is that the problem? If so I'll just upgrade both machines to the newer one but you all know how tricky that is so it would be nice to have a workaround.

Thanks

SoftEther local bridge missing VLAN ID

October 16, 2018, 11:33 pm

Hi all,
not to make too much lines I go directly to the description:
SITUATION:
- I installed succesfully SoftEther v4.25 on OrangePiZero running OpenWrt ChaosCalmer 15.05.1 system, I crosscompiled using OpenWrt SDK environment for CortexA7
- I also instlalled SE on small router 4MB ROM/32MB RAM with help of extroot also using SDK for ramips

In both cases everything works except extroot and swapping memory is so slow that it is almost unusable
In both cases I used site-to-site configuration, one vpnserver and one vpnbridge, it simply makes xxxx km long ethernet cable over internet, no need any IP setting and so on...
Principle is that on vpnserver I need to make local bridge between virtual hub VPN and physical NIC interface like eth0
also on vpnbridge I make local bridge between virtual hub BRIDGE and physical NIC interface like eth0

then SoftEther connects together both VPN and BRIDGE virtual hubs, on first location I put LAN cable to eth0 NIC and on other location this cable "gets out" of eth0 ....

All connections virtual and local bridges got VLAN ID

Problem with Ubuntu is that I get VLAN ID only for virtual connection/session BUT for local bridges I get no VLAN ID
This means that vpnserver and vpnbridge get connected over internet but system dos not work as there is some problem with local bridging...

Does anybody used SE with similar configuration? I tried 2 diffetent PCs and the same problem
Where should I start to look for the problem as to make local bridges to work?

[ubuntu] ubuntu desktop 18.04 networking dns server not added by NetworkManager

October 17, 2018, 11:18 pm

Hello.

I have had a ubuntu desktop 14.04 with manual network configuration. I recently upgraded it to 18.04.
Upgrading to 18.04 has broken my DNS server configuration and I can temporary fix it by editing /etc/resolv.conf.
However, I want to know how to do it CORRECTLY. Can someone help me find the way?

First, I wanted to figure out where my manual network configuration is stored. (Yes, I have not used it for a long time.)
I found nothing in /etc/network/interfaces. I have no files in /etc/netplan.
Code:
obelle:etc > cat /etc/network/interfaces
# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo
iface lo inet loopback
obelle:etc > ls -a /etc/netplan
...
I tried to grep my ip address in /etc and found NetworkManager is having my manual network configurations
Code:
obelle:etc > sudo grep -H "111.222.198.39" -r *
NetworkManager/system-connections/Wired connection 1:address1=111.222.198.39/24,111.222.198.1

method=manual


[ipv6]

I edited IP prefix to 111.222 and search domain to my.domain.com for anonymity.
Yes NetworkManager has both DNS servers but they are never added to /etc/resolv.conf.

Code:

sudo modprobe -r hp-wireless
sudo modprobe hp-wmi

doesnt solve my problem. All other special buttons (fn+f1-f11) works correctly.
fn+f12 light orange and doesnt switch ito green.

In dmesg i cant see rows of driver uploading firmware wifi device. Somesing like this:

Code:
[  34.885470] ieee80211 phy0: rt2x00lib_request_firmware: Info - Loading firmware file 'rt3290.bin'

[ubuntu] ethernet connection not working (DSN problem?) on ubuntu 15.10

Dear users,

I'm a newby of Ubuntu. I've ubuntu 15.10 installed on a laptop and since 6 days I cannot connect anymore to internert via wired connection. I don't know what I did wrong, but I was connected with a VPN and when I disconnected I could not connect anylonger (nor with neither without VPN).

The connection name changed from eth0 to something strange containing my MAC address. I could put the name back following this post:
https://askubuntu.com/questions/6895...rface-in-15-10
but it didn't help.

When I type
Code:
ipconfig
I get:
Code:

There is no product name, but maybe it is normal(?)

However when I type:

I found here

that it might the dhcp server not giving me a DNS server to look up names, but I could not find how to fix it.

Firefox just tells me "server not found"

The Wifi connection does the same.

In the Connection editor I've put IPv6 on "Ignored"

I also deleted the old network names doing:
Code:
sudo rm /etc/NetworkManager/system-connections/...old connection name ...
I have tried to do: (I admit it: I didn't know what I was doing)
Code:

https://askubuntu.com/questions/6905...n-ubuntu-15-10
but it doesn't do anything (I've put it back as it was)

Internet connection, wired and wifi, works on other laptops. I rebooted the box for internet connection too.

I apologize if similar threads have already been posted. As I'm a newby I could not find the solution in all the posts I've read.

Thank you very much for your help

[ubuntu] Unable to install AX88179_178A driver for Gigabit USB 3.0 LAN Network Adapter

The problem is associated to Ubuntu 18.04.

I have 2 debian linux OS laptops. One laptop ( Mint17.3) uses 3.13.0-156 generic kernel. I downloaded the linux driver from ' www.asix.com.tw/ ' and complied / installed it on this laptop. The LAN connection was made and
ethernet interface worked.

Second laptop (Ubuntu 18.04) uses 4.15.0-36 generic kernel. I used the same driver that as installed on first laptop. I made sure build essentials, linux headers, elfutil and libelf packages were install on this laptop before
executing "make and make install". This device doesn't work on the second laptop. Included and attached, are screen shots of the compile/install and listing of dmesg for the usb device.

I did some additional work to install the driver. This time I used
'checkinstall' and got the following results .

This the results of 'checkinstall'

I sent emails to the 'Support@asix.com.tw' identifying the problem but,
they don't respond.

Any idea on how to fix the problem?????
