#StackBounty: #16.04 #apache2 #php Correct way to modify php.ini for Apache and/or CLI

Bounty: 50

I want to change and add some PHP directives, some for apache, some for CLI and some for both. As an example, I want to set the default timezone for all server contexts. There are a couple of different ways I can go about this, but I don’t know which is the best approach.

I can directly edit the master php.ini files, which are here /etc/php/7.0/apache2/php.ini and here /etc/php/7.0/cli/php.ini, but I don’t know whether this file will be overwritten on upgrade. Also for shared settings, such as the timezone, I have to remember to edit two files and keep those changes synchronised.

I can use Apache’s php_admin_value, php_admin_flag, php_value and php_flag directives. The advantage here is that the php settings can be applied on a virtual host by virtual host basis and I can also apply them globally to Apache. However, this doesn’t help with the CLI settings.

The php directory has a similar structure to Apache, allowing files full of directives to be enabled or disabled with the phpenmod command. I can copy this structure, creating the directory /etc/php/7.0/mydirectives, placing php.ini files within this folder, then creating symbolic links from /etc/php/7.0/apache2/conf.d/ to my php.ini directive files. This allows me to have a single directive file which adds directives to both Apache and CLI version of PHP. The only thing I can’t do with this is virtual host by virtual directives.

Any advice on how to do this properly?

#StackBounty: #16.04 #kvm hcp: ERROR: FALLOCATE FAILED!

Bounty: 50

On two Proxmox KVM VMs, I get the error hcp: ERROR: FALLOCATE FAILED! in the console. I get this error on two separate Ubuntu 16.04 VMs.

I am not sure what the error means, or where it comes from. I should note that I saw the error in both consoles after ejecting the installation CD in Proxmox. I re-attached the CD to both VMs just to be sure, but saw the error pop up in the console of one of the VMs again just now.

The VM itself seems to function. I found a thread on the Proxmox forums: Corrupt Filesystem after snapshot, but I do not have any snapshots created for either VMs.

I am confused because I have no idea where the error comes from. Unfortunately, I’m not sure if it appeared in the console before I ejected the installation CDs as well.

I am using R1Soft which loads an hcpdriver. Perhaps that’s related (though I wouldn’t have any idea why it would show these errors).

#StackBounty: #16.04 #keyboard External Keyboard Space Key Somehow Changed to Another Key

Bounty: 50

I am using ubuntu 16.04 on a thinkpad W540 laptop. I have a multi monitor setup that I haven’t used in a few months and now when I try to plug my external keyboard into my laptop to operate my multi monitor setup the external keyboard space key is not working as a space anymore. I think it is acting as a right click because it opens up the menu when I am in gnome terminal.

Note that my laptop keyboard doesn’t have this issue, it is only my external usb keyboard that I plug into my laptop that has this issue.

Here is the output of xev when I press space on my laptop keyboard and my external keyboard.

Laptop keyboard when pressing space:
Key code = 65
enter image description here

External keyboard when pressing space:
Not sure what all this means
enter image description here

I have a dual boot with Arch linux and Ubuntu and I have the same problem on both distros. Both were fine several months ago or so. So not sure if there has been some update or something that changed things, but will great to get my external keyboard working properly again if anyone has an idea what might be happening?

#StackBounty: #16.04 #networking #android #openvpn #intel-wireless OpenVPN is connected and changes IP, but can't reach ISP blocked…

Bounty: 50

I managed to download an OpenVPN file from VPN Gate, imported it and connected it. The VPN was connected and my IP was changed, but I couldn’t access certain page (which I believe it’s blocked by my ISP) as it would like when using my local wireless network. So far as I know, reaching ISP-blocked is possible when using VPN.

I tried, using DNS and direct IP address (also using both TCP and UDP method), but none of them works. I also tried connecting with both wireless and USB wired from my Android phone but none works, too. (wireless is tethered from Android phone)

Though, with same VPN configuration, I can reach the page with my phone.

I’m connected from a phone with LTE connection, and it’s my only source of internet until this post edited.

as well as:

wget ftp://ftp.mondorescue.org/ubuntu/16.04/mondorescue.pubkey
sudo apt-key add mondorescue.pubkey
sudo apt-get update
sudo apt-get upgrade

However, when I run sudo apt-get update I get the following

N: Data from such a repository can't be authenticated and is therefore potentially dangerous to use.

#StackBounty: #16.04 #nvidia #python #cuda #gpu Nvidia CUDA + Theano: Could not find symbol "cuDevicePrimaryCtxGetState"

Bounty: 50

I’m working on an Ubuntu 16.04 and I have a little bit old Nvidia 9600 GT graphics card. It’s CUDA enabled (1.1 computation capability) though legacy. I’m trying to take advantage of it while using Keras and to do so I followed this guide to install CUDA and this one to install cuDNN. The driver for my graphics card is the 304.104 version and the last CUDA version that supports my graphics card is 6.5. After installation I verified it by typing in the console:

Then I followed this recommended installation method and this documentation to install Theano as it’s capable of operating on my graphics card in comparison to TensorFlow. I created .theanorc file

[global]
device = cuda0
floatX = float32

root=/usr/local/cuda-6.5/bin/

[dnn]
include_path = /usr/local/cuda-6.5/include/
library_path = /usr/local/cuda-6.5/lib64/

I also exported proper variables to .profile:

export PATH=/usr/local/cuda-6.5/bin${PATH:+:${PATH}}
export LD_LIBRARY_PATH=/usr/local/cuda-6.5/lib64${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}

However when I try to run this simple test script:

from theano import function, config, shared, tensor
import numpy
import time

vlen = 10 * 30 * 768  # 10 x #cores x # threads per core
iters = 1000

rng = numpy.random.RandomState(22)
x = shared(numpy.asarray(rng.rand(vlen), config.floatX))
f = function([], tensor.exp(x))
print(f.maker.fgraph.toposort())
t0 = time.time()
for i in range(iters):
    r = f()
t1 = time.time()
print("Looping %d times took %f seconds" % (iters, t1 - t0))
print("Result is %s" % (r,))
if numpy.any([isinstance(x.op, tensor.Elemwise) and
              ('Gpu' not in type(x.op).__name__)
              for x in f.maker.fgraph.toposort()]):
    print('Used the cpu')
else:
    print('Used the gpu')

I receive the following error:

I don’t understand this error because in the Nvidia’s documentation this function crearly exists. Does anyone have any clue? Can the problem be that I’m using python 3.6 while in the aforementioned documentation there’s < sign before 3.6? Is any o the paths wrong?
