Rebooting a Linux server unattended – twm’s blog

Posted by jpluimers on 2020/09/21

[WayBack] Rebooting a Linux server unattended – twm’s blog:

/sbin/shutdown -r now

Simple, but I keep forgetting where Linux has short/long command options and short/long verbs.

On my list of things to figure out: how to force fsck with opensuse Tumbleweed on Raspberry Pi 3

Posted by jpluimers on 2020/09/11

Hopefully the below links will eventually get me further in figuring out how to force fsck with opensuse Tumbleweed on Raspberry Pi 3.

For now, I just reinstalled an SD card (my Mac didn’t support the file systems and I did not have time and equipment with me to mount it to another opensuse based device).

Chromium/Chrome on opensuse Tumbleweed ARM notes

Posted by jpluimers on 2020/07/27

Somehow Firefox is available on ARM by default, but the crash recovery isn’t that awesome.

On my list of things to try is Chrome or Chromium. These links should help me find out if this is possible at all:

On Firefox crash recovery:

Eject USB drives / eject command – Unix & Linux Stack Exchange

Posted by jpluimers on 2020/07/20

I always thought than an umount /dev/sdX# for all partitions on /dev/sdX was enough for USB devices to be ejected, but there are three commands that (on most systems) actually power down USB drives (or USB to SD card adapters):

  • udisks --detach /dev/sdX (requires the udisks package which is obsolete)
  • eject /dev/sdX seems not to be enough on some systems; it is part of the util-linux package
  • udisksctl power-off -b /dev/sdX is equivalent to the udisks command; it is part of the udisks2 package.

These will ensure that the disk is not part of the fdisk --list output any more.

The opposite of these is sg_start, which is from the sg3_utils package.

On MacOS, you can use  diskutil eject /Volumes/<LABEL> (source: answer by efesaid on [WayBack] Eject USB drives / eject command – Unix & Linux Stack Exchange)

openSUSE forums tips

Posted by jpluimers on 2020/07/17

A few tips from posting to the openSUSE forums, learned from banging my head to the wall too often.

  • They are at https://forums.opensuse.org/forum.php
  • The forum software can be very slow at times taking ~tens of seconds for loading a post:
    • loading multiple posts or pages of posts you are interested in multiple tabs speeds up your reading a lot
  • Answers on the post often are along the form “has been answered before” without pointing to the actual link, even if the post is marked with a read icon, for instance in [WayBack] No option to “keep me logged in on this device” with Novell/openSUSE login?
  • Your email is not your username, so do not use it during logon: [WayBack] Lousy log in
  • The search function in the forum is horrible.
  • The forum software is proprietary (vBulletin – Wikipedia) and has a
  • When writing/replying to posts:
    1. Edit your answer off-line, because
      • you will automatically be logged off even if the forum indicates you are still logged on (there is no count down of the activity timer), see
      • when you re-logon, your carefully edited text has been lost from the cache
    2. Never use formatting, either auto-introduced, or introduced while pasting, avoid BB-code
      1. Reasoning
      2. Though the forum supports BB code, NNTP news readers do not, and the added formatting gives quite a mess
      3. Use the text (“Source mode”) version of the editor, by first clicking the left most button: “Source”

        • After this, the third and fourth button get greyed out:
      4. Remove formatting button is the second from the left (in both text and WYSIWIG mode): “Remove format”
      5. If you are in WYSIWIG mode, then always paste using the third button from the left that strips formatting: “Paste as plain text”
      6. NEVER EVER paste with formatting with the fourth button from the left: “Paste from Word”
