listing files with ISO 8601 time stamps on *n*x flavours

Posted by jpluimers on 2018/12/05

A (long!) while ago, I wrote about list date with seconds from ls command – Dev Shed that showed how to list the full ISO timestamp (including seconds) of files.

This is an update.

The previous post showed that you could use this statement to list all files with their full ISO timestamps (and therefore get both the seconds and milliseconds) on (open)SuSE Linux, Mac OS X and Cygwin:

ls -l --time-style=full-iso

What Linux and displaying dates in ISO 8601 format… : Little Green Delusions proposes are two solutions to make this more permanent:

alias ls='ls -l --time-style=long-iso'

or edit one of your profile files (he prefers /etc/profile.local, but that is system wide, so I usually prefer ~/.bash_profile) to add this line:

export TIME_STYLE=long-iso

The thing is: I do not always want to have ls -l show ISO 8601 dates. I like the way that ls-l lists timestamps for very old or future files:                 Read the rest of this entry »

how can I free up space on /boot as “openSUSE-2014-462” fails to install on openSUSE 12.3 x86_64

Posted by jpluimers on 2018/11/30

From a long time ago:

[WayBack] how can I free up space on /boot as “openSUSE-2014-462” fails to install on openSUSE 12.3 (x86_64):

Installation of kernel-desktop-3.7.10-1.40.1 failed:
(with --nodeps --force) Error: Subprocess failed. Error: RPM failed:     installing package kernel-desktop-3.7.10-1.40.1.x86_64 needs 16MB on the /boot filesystem

Based on that thread, I figured out the steps:

SSH: Connection Reset by Peer – Server Fault

Posted by jpluimers on 2018/11/22

One occasion I had SSH throw a Connection Reset by Peer on my when was the SD-card of a Raspberry Pi started failing and the ext4 filesystem got mounted in read-only mode.

Then sshd was still listening on port 22, but since it could not write to disk any more, it threw a Connection Reset by Peer to the client.

It was on OpenSuSE Tumbleweed, but would failed just as well using Raspbian.

Lessons learned:

  • IoT hardware will fail.
  • ext4 breaks when the hardware breaks.

Install on openSUSE / SLES – Zabbix.org

Posted by jpluimers on 2018/10/29

Interesting: [Archive.is] Install on openSUSE / SLES – Zabbix.org is possible and there are packages for this on the OpenSuSE site itself for the various kinds of distributions.

For instance, Tumbleweed is at http://download.opensuse.org/repositories/server:/monitoring/openSUSE_Tumbleweed/

Good introductions on Zabbix are via [WayBack] Stephen Fritz on Systems Engineering: Installing and Configuring Basic Zabbix Functionality on Debian Wheezy who has a [Archive.is] zabbix tag.

Other links are at Welcome to workaround.org – tips around open source and Linux stuff.

And there is www.zabbix.com/documentation
