16.04 fails ldap authentication

Sir/Madam

I am having some trouble to get ldap authentication to work in Ubuntu 16.04

I can get it to work in 14.04 ok but so far it fails in 16.04

What I did in 14.04 is

apt-get install ldap-utils libpam-ldap libnss-ldap nslcd

filled in the various details LDAP Server etc

apt-get install sssd libpam-sss libnss-sss

ensured /etc/sssd/sssd.conf , /etc/certs/cacert.pem,
/etc/nsswitch.conf correct

ensure package auth-client-config is installed

/etc/init.d/nscd restart

update-rc.d nslcd enable

This worked every time for 14.04 but it fails in 16.04

Funnily enough my local town has a primary school called "Oeboentoe".

I didn't know but there is a million children on the street in front of
my house holding some "Oeboentoe" banner up above their heads ;-).

He is also violating the license grant, Courts would not be fooled by

The license grant the Linux Kernel is distributed under disallows the

the imposition of an additional term. The communication of this threat

Ubuntu 17.04 middle mouse button problems

I've posted this to all the hardware and software development groups and
Ubuntu forums and received no replies so I'm trying here to see if anyone
else has seen this problem.

System: Desktop dual-Xeon CPU, 32GB RAM, Nvidia Quadro K4000 video,
Sun USB keyboard and mouse.

Everything was working fine for years up through Xubuntu 16.10. I
upgraded to Xubuntu 17.04 and my middle mouse button behavior has changed
drastically.

I have a standard USB three-button Sun mouse with no scroll wheel. In
the past I have had full control over the use of the middle button.

Gnome setup in Ubuntu

Hi

I have previously added the Gnome desktop to a standard Ubuntu install by
sudo apt install ubuntu-gnome-desktop^
I find I can then install shell extensions by opening Gnome Software
and clicking on the Add-ons button.

On a new system, however, I installed Ubuntu Gnome (17.04) directly
and when I open Gnome Software the Add-ons button is missing. Google
has failed to help me. Does anyone know how to get the Add-ons
button?

Apple Time Capsule

Hello, I recived a new 3 TB Apple Airport Itme Capsule. How can I
configure it to make a backup of my Xenial desktop pc? I don't have any
other mac products, I only have PC with Linux (an da Windows vps I can
use if necessary). My idea is to connect it by an exclusive network card
using a crossover ethernet cable and then mount the Apple device in
Xenial and make progressive backups with rsync.

Thanks,

Javier.

Network comprehension question: localhost vs. local IP address

Hi!

The Moinmoin wiki server can be run without configuration, so you can try it,
without the hasszle of configuring everything for Apache. It starts a server at
localhost:8080. This works.

Now I want to try if it works well with my smartphone. I try the address
<a href="http://192.168.178.20:8080/" title="http://192.168.178.20:8080/">http://192.168.178.20:8080/</a>.

Lenovo success except no wireless

Thank you for reading this.

I finally managed to get no-1802 to do it's job, now I can log into my laptop.

One small problem though. I managed to corrupt Windows, through my own carelessness, so I've lost the original Lenovo Windows drivers which means that the wireless network card is turned off. Function F5 (under Windows) should toggle the wireless on and off. Some of the function keys work under Ubuntu but no all.

syslog 101

rsyslog is the Ubuntu default?

I want to run syslog on a Grandstream GXP 1625 IP hard phone. Which
implementation has the least steep (ready easy to get to step one)
learning curve?

I was looking at syslog-ng and the documentation is rather huge. But
maybe there's alternate documentation, or I was just reading the wrong
part. Or, maybe rsyslog would be easier to get going. What are some
recommendation?

thanks,

Thufir

Lenovo 1802 error

Thank you for reading this continuing saga.

Just to recap, I bought a refurbished Lenovo T420 laptop. All went well at until the 1802 (unauthorised network card) error occurred and now I cannot boot the computer. Occasionally I can but not very often.

An Internet search shows that this is a common problem. I have built a no-1802 boot CD but on the rare occasion that I can escape the 1802 error and can actually boot from the CD I'm informed that the CD is not a FAT format although I get a Windows prompt that allows me to continue but nothing seems to happen.

Network Manager problem when changing WiFi connection in 17.04

Another problem with 17.04 that isn't in 16.04.

If you change the WiFi SSID you're connected to by simply clicking on
the new SSID then, in 17.04, Network Manager thrashes around for
several minutes and sometimes fails completely to reconnect. If you
explicitly 'disconnect' from the first WiFi SSID and then click on the
new one it works perfectly OK.

This doesn't happen in 16.04.

(I'm actually running xubuntu 17.04 but I suspect this is an Ubuntu
rather than a specific xubuntu issue)

Further problems with systemd-resolved on xubuntu 17.04

Well, having bodged my domain name into /etc/resolv.conf it seems that
systemd-resolved is *still* somewhat broken.

When I start the system it can resolve local names OK but after a
while (I haven't quite determined how long it is yet, but somewhere in
the ten to twenty minutes area I think) it fails to resolve local
names, as before with SERVFAIL.

If I restart systemd-resolved then it works again.

The result of 'systemd-resolve --status' remains unchanged all the
time.

Notebook won't configure plug-in monitor

My Asus N75SF recognizes that a monitor (HDMI TV) was plugged, but it
fires off 4-8 copies of the Display configuration app, none of which
recognize that monitor.

I haven't tried booting with the HDMI TV plugged in yet, but I'm
wondering if it might be a hardware issue. I didn't see anything in
the BIOS that might be related.

I did try to reset the autoconfigure box of the Display config app -
no difference.

Any clues where to look?

Thanks.

Lenovo Thinkpad and SSD

I've taken the advice offered and ordered a Lenovo Thinkpad T420 plus a 120Gb SSD. I expect these to arrive during the next seven days or so.

In the meantime I'm wondering how I might install the OS on the SSD and place my home directory on the HDD. I have Gparted on a DVD so I can easily shrink the Windows partition and create a home partition of say 50Gb. My question is: how will I make the installer aware that I have my home directory on the HDD? The default action is to install the lot on the one disk drive.

TP-Link TL-WN725N V2 won't connect to my network

I bought a TP-Link wireless nano USB adapter (TL-WN725N V2) to replace a
malfunctioning PCI wireless card on my desktop computer. When I plug the
USB adapter, the system recognizes all available networks, but it won't
connect. It asks me for my password, start connecting... and then my
password again, as if I'd put a wrong one. But I'm sure the password is ok.

The PCI card has been removed.

I use Lubuntu 16.04.02, and have a dual boot with Windows 7. In windows the
adapter works fine
​.

Any clues?

Further to DNS problem on 17.04

I've dug further into this problem, I think the fundamental issue is
that it seems that LLMNR *can't* be disabled:-

root@t470:/etc/systemd# more resolved.conf
# This file is part of systemd.

How to get the systemd resolver to resolve local (i.e. unqalified) names?

Before the systemd-resolved came along my systems resolved local (i.e.
unqualifed) names quite happily, e.g. on my older xubuntu 16.04
systems I can do:-

chris@backup:~$ host esprimo
esprimo.zbmc.eu has address 192.168.1.3

2017-06-14 23:00 UTC: Service Affecting Firewall Maintenance

Hi,

On Wednesday June 14th at 23:00 UTC we plan to perform some essential
maintenance on our Firewalls. We expect there to be a minute or two of network
interruption as we update each firewall in turn, which may affect services
like Ubuntu mailing lists, Launchpad and the Ubuntu wiki. We expect to
complete this work by 00:00 UTC (1 hour later).

The progress of the updates will be communicated by IRC in #canonical-sysadmin
on Freenode by Paul Collins (IRC nick pjdc).

Recommend laptop

I know this is a frequent question, however it hasn't been asked for awhile and I'm completely overwhelmed with choice.

I've owned two ASUS laptops, both died after developing intermittent faults within four years. I was given an MSI CR620 but it has now developed an intermittent keyboard fault. I was also given a Toshiba A100 and this has been totally reliable but it's frustratingly slow under Xubuntu. I'm not sure about HP laptops. They are the cheapest of the bunch, but how long will they last?

I'm not looking for high specs.

external mouse/keyboard only works after reboot

I connect my laptop to external mouse/keyboard/monitor through a Dell dock
TB16.

When hotplugging the laptop to the dock, the external monitor always works
fine.
Mouse/Keyboard requires a laptop reboot to work.

How can I troubleshoot this?
I am looking for a better solution than rebooting, a driver to reload or
service to restart.

unable to install ubuntu 16.04.2

Hi,

I downloaded the Ubuntu 16.04.2 iso, and created the DVD. when I tried to install this
on a Windows XP machine and also a Windows 7 laptop, in both cases I get a purple screen with at the base of the screen a pictogram of a rectangle followed by

nothing further seems to happens.

why am I unable to install 16.04.2?

financial app recomendation

I have tested some financial apps like gnucash, moneymanagerex, and
others, to manage my money. I want a solution that includes a central
storage in my pc, and Android applications to store transactions offline
from the phone when I am not near the computer. Money Manager Ex does it
quite good, but in phones was automatically updated (and there is not
such version for pc) and the program stopped the data sync. Gnucash is
quite good but lacks of automatic data sync from android version to pc
version. Which solution do you recommend me?

Scanner software recommendation

I have an HP OfficeJet 5710 All-In-One attached to my Xubuntu 16.04.2
home desktop that I've been using for over a year now. I use xsane for
the scanner software, but I'm not at all happy with it. It forgets
half of its settings every time I switch from ADF to flatbed (mainly
resolultion and paper size), and it doesn't handle multi-page scans
well at all.

amdgpu_Pro - kubuntu 16.04.2 plasma shell crash at logout

Hi,

I've installed Kubuntu 16.04.2 plus the amdgpu-pro driver 17.10 from the
AMD-Page. System: AMD-processor, 64bit, 16GB RAM; AMD Phenom(tm) II X4
960T Processor; AMD Radeon (TM) RX 460 Graphics

Everything seems to run fine, except when I log out, the screen turns
black, shows an error message and returns after a short while to the
login mask. No other problems, so far.
I cant't recall having a crash before I added the amdgpu-pro-driver,
i.e.

root only on newly initialized sata drive?

I have booted a live 16.04 and used gparted to remove the partition
then recreate it and format it to ext4. Fine so far. When trying to
save to the the drive I can't unless I use sudo. The permissions show
the drive's only partition is owned by root. How do I change this? I
know how to chown but don't see why it's created as root-owned by
default.

Replace boot drive

It's probably time to replace my boot drive on my desktop running 16.04.
I bought new 2TB spinning disk much larger than existing.

What is best way to do this?

mouse / keyboard input oddity

Since upgrading to Ubuntu Mate 17.04 I've experienced a slightly irritating
problem. After a short period of inactivity (not sure how long but <30
mins), when I return to the PC a mouse click or a single key press will not
achieve anything. Keyboard input is accepted on the second key press, and
mouse clicks are accepted only after I have pressed a key on the keyboard.
Ctrl-F (say) seems to work immediately, however.

Has anyone else experienced this? And is there a simple solution?

There is a similar situation when I try to log in. I have it set so that I
can log in without a password.

File system only mounts with gparted

I just updated my Xubuntu 16.04.2 to the latest kernel et al, and when
I rebooted, one of my drives did not mount.

Files manager force file extension

It seems that ubuntu(16.04LTS)'s file manager, whose name I don't know, will
stupidly force users to save file with a specific file extension. For example,
when I save the html page from `https://www.yahoo.com', I only got two options
in the file manager (at the lower right corner):
"Webpage, Complete" and
"Webpage, HTML only",
By default, I get `Yahoo.html' as the filename to save. I can change the
`Yahoo.html' to any name like `this-is-yahoo.html'.

Changing defaults for all users to be created in the future

Hi all,

I'd like to change some of the default setting for all users created on an
Ubuntu 14.04 system. Something similar to changing the /etc/skel/ - but in
the GUI.

For instance, the default key binding to change the keyboard layout (Called
'Switch to next source using:' in Text Entry).

How do I do this?

Thanks!

Browsers hang on moodle site

Hello!

I work with Moodle sites, and in one of them my browsers (Firefox, Chrome,
Opera) stop working whenever I activate edit mode on Moodle. They just stay
loading the page when I try to edit anything on the site, for a couple of
minutes, after which they return to the home page.

Now, this happens while running Ubuntu (I tested on Ubuntu, Lubuntu, Ubuntu
Gnome, Linux Mint) but not on Windows, nor Fedora! Additionally, this does
not happen on browsers based on Webkit, at least not on Epiphany or Midori.

This particular site is on Moodle 2.9.5+ (Build: 20160317).

ubuntu 17.04: cut and paste middle mouse not working?

With the new Ubuntu 17.04 I don't seem to be able to do the classic "left mouse select and copy- middle mouse paste" action. I looked for an options, but found nothing,.

This is an old-timer X windows thing from probably 30 years ago, and I've seen this feature deteriorate over the past few years. Not quite understanding when it doesn't work, but it sometimes seems to remember another buffer when I switch windows. I have to deselect that one, and re-select the buffer i wanted. Painful.

Can't boot notebook from SSD

I know this has been around, and I've posted before when I had this
problem with my desktop boot SSD (which was solved - it needed the
UEFI boot space at the front of the drive).

I was able to do a near-complete install of Xubuntu 16.04.2 on the
drive using my USB flash drive. All went well until I had to reboot.
All I get is the flashing undersccore cursor.

At first I didn't even get the grub screen, but I made some
adjustments and that at least comes up.

Adjustments:

1. Added the UEFI boot space and reinstalled.

font oddity

Sometimes, for reasons that are unclear to me, my display changes
subtly.

The fonts in some windows become less clean, change their
aspect ratio, become spindlier and less dense. The themes in some
applications regress fifteen years. The window decorations remain the
same, though.

It doesn't affect all windows - for example this message
window looks exactly as it did before, but the parent window
(evolution) is displaying differently.

attempt to read outside disc hd0 you need to lead kernel first

Last two times I booted I've gotten

BusyBox v1.21.1(Ubuntu 1:1.21.0-1ubuntu1) built in shell(ash)

(initramfs)_

It says to run a manual fsck which I did with fsck /dev/sda1, the petition
in question

Worked the first time, now I get

"attempt to read outside disc hd0 you need to lead kernel first"

Hard drive or memory failure? Smart drive says disk is ok. I can run ubutu
from a usb just fine. Is it worth doing a mem test? Or just try to
reinstall ubuntu- that would reformat the hd, no?

thanks

What exactly should the search in gnome-shell do?

I am trying out the gnome desktop in Ubuntu and am confused about
exactly what the search feature in Activities is supposed to do with
regard to files searching. The feature is accessed by bringing up
Activities and typing in the search field.

It appears to find files both by name and content, but does not seem
consistent in exactly what is found. I have not managed to find a
complete description of what it is supposed to do. Does anyone here
know?

Desktop files and Gnome

Since I am going to have to wean myself of Unity I decided to give Gnome a go.

I have a number of home spun .desktop files which I have added to the
Unity launcher which allow alternative actions on right click. For
example I have one that by default gives me a terminal, but by right
clicking I can ssh into a long list of servers. I have tried adding
the opening the application using the desktop file and then adding it
to Favourites in the panel, but the right click does not give me the
options. Is there a way to achieve something similar in Gnome?

Ubuntu Linux and firewalling and dual NIC's

Hello.

I have a firewall/gateway computer, that has two network cards, and we
are soon to change from ADSL to the (Australian) soupy-doupy NBN thing
with supposedly higher data transmission speed capabilities, which
means a new modem/router thing with which to interface, and so, new
settings (or so, I expect), which means, in the context of the status
of the firewall/gateway computer, replacing the operating system and
firewall software.

I have thus far, used Ubuntu Linux only as a workstation operating
system, which does not involve two network interfaces; two NIC's, and
so I need to know w

Accessing mounted drive from snap package

On Ubuntu 17.04 I have installed the keepassxc snap package using
sudo snap install keepassxc

I have a remote (samba) drive permanently mounted via fstab as /media/drivename

In order to access a keepass database on the mounted drive I have to run
sudo snap connect keepassxc:removable-media :removable-media
which seems odd since the drive is not removable.

Even then I am not able to browse to /media, but have to enter the
full path in the filename dialog in Database > Open in keepassxc.

Is this a limitation of snap packages? In which case it is not a very
user friendly feature.

freeipa-client not found on x86_64 install against 64-bits only mirror

I'm having an issue with preseed that my install cannot find the
freeipa-client package when I use my own local mirror which only
contains the 64-bits packages.

I have tried to set:

d-i apt-setup/local0/repository string [arch=amd64]
<a href="http://local.server/ubuntu" title="http://local.server/ubuntu">http://local.server/ubuntu</a> xenial main

But that doesn't work.

When I manually add [arch=amd64] in all deb lines like deb
[arch=amd64] after the install has finished and I do an apt-get update
and I search for freeipa-client the package is found on my local
mirror.

What is wrong here ?

Machine check exception, but what kind?

I've been having trouble with two of my personal computers. One is from
System76 and their great support staff suggested I load package mcelog to
monitor for machine check exceptions (MCE). Sounded good to me, so I did
it on all my Ubuntu machines (I have 4 if you count laptops).

Lo and behold, one of the other machines glitched last night. Not the
System76 one, but a home-brew I built myself (with a little help from my
friends). It's got a medium-fast Core i-7 on an ASUS board.

How to tell which version of a application is running

I have two versions of tracker installed, one through the system
install of 16.04LTS

apt-cache policy tracker
tracker:
  Installed: 1.6.2-0ubuntu1.1
  Candidate: 1.6.2-0ubuntu1.1
  Version table:
 *** 1.6.2-0ubuntu1.1 500

The other,

tracker --version
Tracker 1.12.0

I installed from source recently hoping to stop tracker from filling up
my syslog with notations such as I've posted here - https://pastebin.co
m/rWpuwgEJ every time I restart the system when required (although it
hasn't stopped as you can see by the date in the log entries).

Question is, which version of tracker is running?

PRINTER DRIVERS

Hi,

I got an old but unused printer from a friend. I didn't want to use it
because it is a rather poor printer. However, my primary printer died
and I want to use the printer until I get a new one.

I set the printer up and the Linux operating system identified it as
"Dell Photo 48WG71". This identification seems right but the OS was not
able to identify what driver to use. I visited the Dell site and they
don't even identify the printer they sold.

Add user to sudoers again

Hello,

I run this command:

I forgot the "-a":

Now myuser is not a sudoer so I can't add it to sudoers and I have no
root password since I never needed it before.

Can it be fixed somehow?

Thank you!
