Connecting WD MyBook (WhiteLight) TB drive via Router

Good morning,

I have recently moved from a system based firewall/server to a router.

Router is a Belkin N600DB wireless router. I have been able to get
everything up with the exception of my MyBook (worked before as a
dedicated host using NFS to access it). The router fails to find it when
I plug the network cable directly into the router.

What am I missing...

Belkin claims no support for Linux. Suggested I try one of the other two
popular OS.

sync hangs

I'm having problems accessing a usb card that I've been trying to write
to. In Caja I get an error saying "An operation is already pending"
If I type sync on the command line it hangs.
I see from ps that there are three sync processes in uninterruptible
sleep and I can't kill them. I assume this is the problem.

What's the best way to proceed? I'm using Ubuntu Mate 18.04 with

Output from 'groups' is suddently different to /etc/group

How would I know? I was just looking for something like VirtualBox, to
play around with a different distro. All in user space.

Now I would think twice about installing all that stuff.

As far as I remember, Synaptic did not tell me that I had installed
something ground-breaking, or that I had to log off or reboot
afterwards. Or are you expecting end-users to read the installation log?


Output from 'groups' is suddently different to /etc/group

Yes, but how would I know that the package I just installed has changed
group membership?

Which is better? Microsoft Exchange 2016 or Linux-based SMTP Servers?

Good evening from Singapore,

I am torn between deploying Microsoft Exchange 2016 and Linux-based
SMTP servers like sendmail, postfix, qmail and exim.

Relative ease of installation and configuration is an important
consideration factor.

Microsoft Exchange 2016, Domain Controller, and Active Directory are
relatively easy to install and configure. Linux-based SMTP servers are
extremely difficult to install and configure and of course, extremely

One of the features of Microsoft Exchange 2016 is that you can create
additional folders on your Inbox in the server (server-side).

Changing the default for "Enter a passphrase to unlock the volume"

about this for a while.)

When you insert an encrypted USB stick (e.g., LUKS), the "Enter a
passphrase to unlock the volume" dialog comes up, with three options:

O Forget password immediately
* Remember password until you logout
O Remember forever

with the middle one as the default. I want the first one (forget
immediately) to be the default --- is there any way to change that,
either per-user or for the system?


Kubuntu boot time: 16.04 -18.04


I have on an SSD three OS with KDE and the boot time differs between
them. All are updated.

Each from the boot selection menu to the login mask

Kubuntu 18.04 50s
Kubuntu 16.04.4 21s
opensuse Tumbleweed 16s

Significant is the boot difference between the two Kubuntus.

I would like to check the different log files, which should I look for?




I was trying to install Tor and now I my mouse cursor indicates that
something is waiting for input.  I executed ps  to see what is causing
it and I find a utility running called /sbin/agett.  I ran the man pages
and it seems to be a legitimate linux utility but I still am uncertain. 
Is this needed or is somehow related to the recent Tor installation?

I don't like something running in the background waiting for some
unknown input as indicated by the mouse cursor being a circle that is
rotating.  If it is unnecessary, should I get rid of it or simply
disable it?  Also, I looked in

Ubuntu 18.04 and wine

Dear All,

how to get wine running on Ubuntu 18.04 64bit ? unfortunately I'm not
able to get it working on Ubuntu ( it installs without issue but unable
to run any "exe" using command wine nameofexe.exe )


What did I just ruin?

I may have outsmarted myself.

I was about to upgrade packages and I wanted to capture the plethora of
messages I expected
this to produce, so I did it under script(1). It captured all right, but
I'm a bit worried by a thing it
captured a few times...

For instance, at the end of fetching packages....

18.04 = circular login problem on system freeze

I just installed 18.04 this week and have been testing it out.
Earlier today I clicked on Show Applications an the screen froze.
After several minutes it logged me out and when I tried to log back in -
Im immediately logged out. This is a similar problem I was having with
17.10 recently. (This is a fresh install).

Thankfully I have a second account to login with and I was going through
the logs looking for something .. anything at the time this happened.

Looking for ratings of all-in-one printers for Linux (Ubuntu in particular)

I know there are probably multiple places where such ratings can be found.
Not knowing which are reliable, I'm sort of asking for ratings of the
ratings, I guess. Mostly, though, I want ratings of recent models, from a
Linux/Debian/Ubuntu perspective as opposed to the usual Windows slant. I'm
presuming the few machines that I dual-boot will be able to work with
whatever printer I have.

So, where to look?

After update, login loop

My assistant was working on the laptop when a update popped up.
She said it was just an update so I said allow .. it was a upgrade.
So my 16.04 went to 17.10. What a mess. Now though the login
screen is stuck in a loop. Doing some research this must have been
somewhat of an issue because I found lots of posts on it. None of those
solutions are working. The first thing they say to do is Ctl+Alt+(F1
or F3) to get into login terminal. That doesnt work at all.


wxWidgets error while compiling pgadmin3-1.22.0 in Ubuntu 16.04 LTS


I am trying to run ./configure to install pgadmin3-1.22.0 from source

Can somebody suggest how to get wxWidgets for Ubuntu 16.04 LTS? Thanks.

Strange sudoers problem.

I have an odd problem with sudoers. Recently, I've tried to make use of
/etc/sudoers.d/ rather than editing /etc/sudoers itself. This, in theory,
should ensure that future upgrades to sudo will not munge my additions by
leaving the stock /etc/sudoers intact. Research has lead me to believe that
files in /etc/sudoers.d/ need to be dot files (I.E. a "hidden" file) and
need to be mode 0440. I have done both of these things, however, the groups
I define for sudo access in my /etc/sudoers.d/.devops.sudoers file are not
processed, even after a reboot. Anyone else have this problem?

Disable sound?

Hey, all. Is there a good way to entirely disable sound? I'm running
Ubuntu in a VM, and, for reasons I haven't entirely discerned (and don't
have time to troubleshoot) Chrome + sound + HDMI-at-home = bad news.
V-e-r-y slow response, etc., etc. (Firefox works fine, but I'm already
settled into Chrome.) As it's running in a VM, I'm more than happy to
use the host OS to do audio (a Mac).

So, anyway: maybe blacklist the audio kernel modules? Or...?

Web Site Down?.....

Dunno if anyone's aware? But I've been trying to download Ubuntu MATE's
.iso file since around 1PM EST, and when you click on the link for the
download nothing happens. I guess they're performing some kind of
maintenance? Because I also went to Ubuntu's home page, and Ubuntu

links for their .iso files.

Just in case anyone was wondering.

IPV6 addresses

When I run ifconfig on an 18.04 machine which has been upgraded over
several versions I see an IPV6 address generated from the MAC address
of the form
which has been generated using the technique in
<a href="" title=""></a>.

On another machine with a fresh install, however, the fe80:: address
does not have any obvious relationship to the MAC address and has not
got ff:fe at the appropriate place. I deduce from this that there
other allowed techniques for generating the address but I can't find
any reference to them anywhere.

System Update froze - UbuntuMATE 16-04


I have tried to do a system update on this computer, which is (kind

dual-boot time issue

Hi all,

It seems I'm bothered by an old issue again, though googling tells me, I am not the only person effected....

The general issue arrises when dual-booting:
Ubuntu_18.04 uses UTC, derived from NTP
Windows uses Local Time, derived from hwclock.

Normally the two can co-exists together, except, when stopping Ubuntu, System-D writes its time back to the hwclock.
No big deal for Ubuntu (as it will use ntp), but a source of irritation under Windows.

I do know several suggestions, like:

a) Make Windows10 use UTC instead of local time.
This would solve everything once and for all FOR ME

Is it possible to download packages from 16-04 repository to install on 18-04


It has occurred to me, as the Ubuntu Software Centre, Me TV, NetSurf,
and various other packages in 16.04 are not available in 18.04, is it
possible to download packages from the 16.04 repository, and, install
them in 18.04?

If so, how do we access the 16.04 repositotory and download the 16.04
packages, from 18.04?

Thank you in anticipation.

Me-TV and ubuntu 18-04


I have a UbuntuMATE 18.04 installation.

The Software Centre of previous versions, and, apparently, many other
packages, have been disappeared, in the change to 18.04 - they were in
previous versions of Ubuntu, but are not available in the (clean)
installation of Ubuntu 18.04 .

The Me TV application was the only TV application that I could get
working on 16.04.

The Me TV website makes it prohibitively difficult to contact any of
the Me TV people.

Are any of the MeTV developers on this list?

We have an sftp server with 10 users and only *one* needs to access the

it works but if a user create a new directory/files will not apply to it.
