backuppc "no ping response" when ping works fine

It took me some time to figure this out, maybe it can be useful to someone else...

I kept getting "no ping" error for unknown reasons. It turned out that I had enabled DumpPreUserCmd and UserCmdCheckStatus for that specific host to check for an encrypted partition being mounted.

Due to some changes on the host after an upgrade, the script triggered by DumpPreUserCmd was returning an error... And for some reason this showed as a ping error in the web interface.

I eventually figured it out by checking the last lines of the LOG.** file in the pc/[host] directory, which looked like this:
2018-05-08 19:15:45 Output from DumpPreUserCmd: /[partition] is not mounted
2018-05-08 19:15:45 DumpPreUserCmd returned error status 256... exiting

How to solve Edimax EW-7612UAn v2 (7392:7822) power management issues on Raspberry Pi (Raspbian WiFi disconnect)

  • On Raspbian, you don't need to install the 8192cu driver manually, as it comes with the distribution

  • To avoid disconnection issues, you need however to disable power management. This needs to be done in two places. First, this is what I have in /etc/modprobe.d/8192cu.conf:
    options 8192cu rtw_power_mgnt=0 rtw_enusbss=0

  • This alone did not prevent the issue. I also had to add this entry to /etc/network/interfaces:
    auto wlan0
    allow-hotplug wlan0
    iface wlan0 inet dhcp
    wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf
    wireless-power off
    iface default inet dhcp

Accessing iPhone (iOS 10.2.1) pictures from Ubuntu

Recent changes introduced with iOS 10 prevent you from mounting an iPhone on a regular Ubuntu installation.

The PPA by Martin Salbaba used to fix the issue, but it hasn't been updated in a while, and now when I connect my iPhone (running iOS 10.2.1) the pictures are no longer accessible, although the documents are still there.

This solution worked for me (Ubuntu 16.04):

- install libimobiledevice6 + dependencies from this PPA: https://launchpad.net/~martin-salbaba/+archive/ubuntu/ppa+libimobiledevice (follow the instructions there)

- install newer libimobiledevice version according to the "recipe" by A.B. here: http://askubuntu.com/questions/598940/libimobiledevice-1-2-ios-8-support-for-ubuntu-14-04-trusty

- install ifuse according to the same method:
cd ~/src/
git clone https://github.com/libimobiledevice/ifuse.git
cd ifuse/
sudo apt-get install libfuse2 libfuse-dev
./autogen.sh
make
sudo checkinstall

You can now mount your iPhone like this:
mkdir ~/mnt
ifuse ~/mnt
I assume the same procedure would work for an iPad too.

Add Ubuntu alongside a pre-installed Windows on an HP laptop (convert primary partition to extended/logical)

Recently I wanted to install Ubuntu next to a pre-installed Windows on a brand-new HP EliteBook.

The notebook came with four primary partitions, with Windows installed on the biggest one:

- sda1 (1 GB, NTFS, label=SYSTEM)
- sda2 (457 GB, NTFS)
- sda3 (16 GB, NTFS, label=HP_RECOVERY)
- sda4 (2 GB, FAT32)

In order to install Ubuntu it's not enough to resize the Windows partition, as you cannot have more than four primary partitions. Removing one of the other partitions is a bad idea according to several reports, as it might render the system unable to start, or prevent BIOS updates. So the idea is to convert the Windows partition to a logical one in addition to resizing it. Fortunately everything you need to do that is already included on the Ubuntu installation image.

1. Use gparted to resize and move the Windows partition. I resized it to 100 GB and added 10 MB free space before it (to leave some space to create the extended partition later on). This will take a while, depending on the performance of your hard drive.

2. Use fixparts to convert sda2 to a logical partition:
# fixparts /dev/sda
Type l then 2, write the changes to the disk with w.

3. Restart the computer without the Ubuntu install media so that Windows fixes itself. This will take even longer than the partition resize, be patient. Restart once more to make sure the Windows install is fine.

4. Proceed with installing Ubuntu, choose the option to "install Ubuntu alongside Windows".
