Can see my NFS share but not the files/folders inside it

Sat, 01/06/2018 - 17:30
On Linux Mint 18.3, I have a folder shared out via NFS with lots of files/folders in it. The share appears to be setup correctly and I can mount it from my Antergos box but when I go into it from Antergos, it's empty.

I'm sure it's a permission issue of some kind or how I'm sharing it out. Any tips?

In my /etc/exports file on Mint, I have tried the following:

/mnt/md0/data *(ro,all_squash,insecure)

That last one.... I'm sure the anonuid and anongid is wrong for me..... somebody posted it in a forum and since this was my 3rd attempt at trying to make this work, I just left all the default stuff in. Everything in that folder is drwxrwxrwx and when I type showmount -e, I get:

Export list for server-pc:

Side question. A few weeks back, I was experimenting with a Synology box and mapped an NFS share on it from my Mint box and when I type showmount (no switches) I get:

Hosts on server-pc:

I have no idea where to go to nuke that old entry. (I'm almost positive that was the IP address of my Synology box that is no longer in my house.)

Kubuntu 16.04: Dolphin crashes on Activities

Sat, 01/06/2018 - 15:29
Hello experts,
I have Kubuntu 16.04. It is x64. Running on a Core2Duo 2.93 GHz.
I applied all updates.

This is not such a big issue but ...
I open Dolphin (the Linux file manager), Right click on a blank area.
You get a popup menu with Open With, Actions, etc.
If I hover my mouse over Activities, Dolphin crashes immediately.

I attached 2 screenshots.

I did a web search and found 2 threads from 2010 on the net. 2010?

I must say I am a newbie in terms of virtualization, I'm planning to study one of this (proxmox, vmware).

What should I study first? For the pro and experienced users what would you recommend or any tip/advice? thanks.

X server freezes system on shutdown in Slackware 14.2 with a Dell Inspiton i13-5378

Sat, 01/06/2018 - 14:18
I have recently installed Slackware 14.2 on a Dell Inspiron i13-5378. When I try to shutdown the computer (either poweroff or reboot command) half of the time the system will freeze at a black screen with a blinking pointer and will not respond to anything but forcing shutdown by holding the power button. Recently I found that the same happens when I close the X11 using crtl+atl+bckspace, so I concluded this was a bug from the X11.

I tried to find informative logs on /var/log but I'm not sure where to check for the error. I'll be happy to provide any log or command output needed. I'm using i3wm.

The Xorg log after a crash is annexed.

Any help on debugging this X11 shutdown problem will be appreciated. Thanks.

Sharing folder on network for scanning from netwirk printer Linux Mint

Sat, 01/06/2018 - 14:04
Hi there again, wonderful Linux World! Thanks for all the help so far!
Here is another question from a newbie and a pc "Dummy".
I need to be able to scan from my network printer/scanner to a folder on Linux Mint machine on the network.
I went to the sharing option in Nemo, it asked to click install Samba which I clicked, it seemed to do it, asked me to log out and in.
Then I ticked the two options in the Sharing tab in Nemo (allow read/write and allow guest access).
Now - what is the name of the folder on the network that I need to enter into the network printer/scanner interface?
In old Window$, the sharing option in the File Explorer displayed the folder name on the network (eg \\MyPc\Scans. I entered that into the scanner interface and it worked.
What is the procedure with Linux? The folder is on my desktop, its address there is /home/me/Desktop/Scans. I am using Linux Mint Cinnamon.

What computer to buy?

Sat, 01/06/2018 - 13:53
Hi I am new to Linux and the first thing I need is a computer to start learning it on. I would prefer a dedicated Linux laptop that has everything I need to make the experience of learning linux as smooth as possible but don’t want to spend a ton of money as I may find I am not successful with it. Also would want to be able to convert it to a windows computer if I wasn’t successful at learning Linux. I have been reading and searching but as I am really not a computer person at all my head is spinning and I really need some advice. Thank you in advance for any help that can be offered.

Printing on Linux? Experience with printers from HP?

Sat, 01/06/2018 - 13:46

I am looking at getting an printer, preferably a multifunctional printer in order to both print and scan/copy things.

I've searched and read a little bit on how well printing should work in Linux, and for a printer that seems good. Right now I'm looking at HP, they seem to have a pretty solid support for Linux.

HP Color LaserJet Pro 200 M277dw seems like a good printer:

Connecting the printer via USB or wired ethernet would be enough for me.

- Would a HP printer be a good choice for use together with linux - or would you recommend something else?
- Does anyone have experience with printers from HP, do they work well?
I see that a proprietary binary plug-in is often required for full functionality. Has anyone used this?

Thanks for your help :)

[QEMU-GA] Slackware as a Proxmox guest.

Sat, 01/06/2018 - 13:10
I have Slackware 14.2 running as a guest under Proxmox, unfortunately it doesn't have qemu-ga installed, so it is difficult to make proper backups. I have installed, but it won't start giving me:

Code: 1515243754.365461: critical: error opening channel: No such file or directory
1515243754.365475: critical: error opening channel
1515243754.365487: critical: failed to create guest agent channel
1515243754.365488: critical: failed to initialize guest agent channel Is it something else I need to install or configure?

Why do some tools (e.g. ffprobe) split their output between sdtout and stderr ?

Sat, 01/06/2018 - 13:07
If you want to grep in all output (or want to write all to a file), you always need to 2>&1.

I understand that tools whose purpose is to process some input and write the result to output (e.g. sed) need to handle output and error messages separately. Another example is wget, where you only want to have the downloaded content in stdout. For all these, I think splitting is fine.

But I don't understand this behavior in tools like ffprobe, whose purpose is to analyze a file and then write the result.

Server process load or client process load?

Sat, 01/06/2018 - 11:24
I build a web server. It's running on a VM environment. I configured it to index the files in my directory.

Now all files are videos (.mp4) I clicked it, and it streams on my browser.

Now my question is who's the one that process the video much more? The server or the client?

I do top on my server and its 99% idle. Btw, I'm playing the video 2 instance at a time.

I have tested the Orange Pi Plus 2E in -current:

This device has 2GB RAM, which is nice.

and have updated the installation documentation:

I've decided not to incorporate any HDMI patches into the 4.14 Kernel since the only ones I found were for a newer branch, and we need a long term supported Kernel now (which 4.14 is scheduled to become).
