From cycling to computer systems performance – Part 1

This is my first longer blog entry after getting back to a more frequent blogging schedule. It will be a two part blog entry. It may start with cycling,...

Problems of a vegan

I'm vegan for a while. I'm not a health vegan, because it's perfectly possible to eat totally unhealthy as a vegan. I'm the living proof. I'm not really doing...

Thoughts about PoE security cameras (and outdoor Ethernet cables in general)

I'm currently trying to buy a security camera, because I have the suspicion that people are using my property as a shortcut. I had just one thought: There are...

Koblenz — again???

Changing Unifi inform URL via SSH

Feuer&Flamme

I'm currently working on a longer blog entry about measuring systems performance, but this will take some additional days. Meanwhile I would like to point you...

Strangest things

I have seen and experienced a lot of things when driving on the Autobahn through Germany. I have seen quite a few crashes, smaller and larger ones. To this day...

Suspiciously new

I wrote this morning that my house has currently no VDSL internet, just cable internet. I'm just back from the street in front of my home. Roughly 50 m away...

Redundant

The street in front of my house gets a new cycleway on the inbound side of the street. While this is a really great idea because the old one was in an abysmal...

Docking

I wanted to get rid of a significant set of cables when I set up my new desk, there were a gazillion cables flying around on my desk and I wanted to bring that...

You get vastly more aware of your own ageing when you listen to live music on YouTube from musicians roughly your own age and look at them changing over time....

Workarounds - revisited

The example with the heating system is a better example than I thought. I learned some additional things over the course of the day. There are workarounds that...

Workarounds

Sometimes you may think that IT is the only business where workarounds are used. Today I was reminded that other businesses do the same and some even make...

500000

I wasn't able to exactly hit the number, but yay — half a million kilocalories. The screenshot shows calories, but the tool is making the same error like most...

Keyboards

It's roughly 20 years ago that I switched to use notebooks for work. Before my time at Sun I was able to convince my manager that I really needed the Powerbook...

Åskväder

A few days ago, I needed some distraction and thus I drove one of my sisters to IKEA. I needed a desk lamp[^1] anyway and thus this looked like a good idea. At...

Smartbike

This summer wasn't that good in regard to cycling. It wasn't good at all. First half of the summer felt like a never-ending row of rainy days. Then a lot of...

Xodus

A while ago I left X as a user (the website formerly known as Twitter). I assume out of the same set of reasons why most people I know left Twitter. I really...

I'm just in the process of cleaning up the blog and updating some static pages. The cleanup was necessary to be able to run the scripts to publish new blog...

The joy of solving performance problems - Part 1

It took me some more time to have this first part ready, because I revised it quite a lot and in the recent evenings I didn't want to spend the necessary time...

The joy of finding performance problems - A foreword

# A journey Many interesting journeys start with a first step. There are lessons in them and no matter how much you have seen in the past, you always learn new...

Visualize

"The Matrix" ruined it a little bit for all of us. Outsiders have sometimes the impression that admins can find errors on their servers just by staring at the...

Potential energy - or how to maximize your XP points in Zwift

Of course I prefer to cycle outdoors. However when it's rather cold and dark when I usually start to cycle the motivation is significantly reduced. In such...

Changing passwords as a role

Of course the privilege to change other people's passwords can be encapsulated into a role, so you have an additional authentication by using the role password...

Additional information for your zone configuration

Sometimes it's useful to enrich your zone configuration with some additional data, so someone can look into the zone config and know for example who is...

Changing passwords - re-revisited

There was an interesting question on Twitter after I published my blog entry about assigning the authorization to change passwords to regular users: "Can you...

Tiered storage with ZFS

This is another blog entry in regard to ZFS and about what you have to keep in mind about it when working with ZFS . It's nothing really astonishing, you just...

vmstat without history

Historic values are sometimes quite useful to have an overview of what's happened in the past on your system, but quite often it's only something you have to...

Authorizations for Zone Console access - Part 3

Okay, there is one remaining obvious question. What if you have an admin that is responsible for all the systems and you want to give her access to all the...

Authorizations for Zone Console access - Part 2

As I wrote yesterday, there is an alternate way to configure zone console access. Let's assume we want to give the user junior the authorization to access the...

Authorizations for Zone Console access - Part 1

When you wanted to access the zone console on a Solaris system as a normal user in the past, you needed an authorization. You may remember from a very old...

Increasing ZFS pool sizes

I had this discussion with a number of customers in the past, because it's one of the not so obvious consequences of the inner workings of ZFS , of how ZFS...

Some of these improvements are not really new. They were in Solaris for years, however they were not really documented and while many people knew about them...

Lock it up

This is a quite useful tool. Let's assume you are working with colleagues on a system on their desktop. They are working on their shells as unprivileged users,...

The command fsstat (somehow a command relatively unknown when talking with customers) got a slight enhancement in a Solaris 11.4 SRU . Before this enhancement...

Clean up after yourself

This is a rather small change in one of the Solaris 11.4 SRUs. SMF had so far three methods. You could have a start method, which is as the name says meant to...

Tales from the bike saddle - Feeling/being superior to whom?

The film "Kingsmen" is totally over the top, somehow still fun and you learn from it. For example what the hell brogues are. That you should know how a bulldog...

Even more new options for svcbundle

Another addition to svcbundle was the ability to set * user * group * privileges to directly create manifests for SMF that didn't need manual editing to adhere...

Homedirectories

Even such venerable tools like useradd could use some extra features. In a recent SRU an option was added to set a default for how the home directory is...

iostat and microseconds

Solaris 11.4 got a small extension to the iostat command. In a time when storage gets faster and faster, you may end up in a situation where the wsvc_t and...

Jitter and delay for svcbundle generated SMF manifests

Another extension to the svcbundle tool is the introduction of -s delay= and -s jitter= for periodic SMF services. If you have something to start in a periodic...

svcbundle extended

New -s option for zpool status

With SRU 30 of Solaris 11.4, the zpool command got a new option for the status command. You can now get some additional information about the devices. This...

ZFS allocation units

This feature introduced in Solaris 11 SRU 30 is really an interesting one. It's nothing you should really need often because usually ZFS will do the right...

You have been warned: Upgrading rpool

In the past customers painted themselves into a corner when they did a rather large jump with their OS versions, upgraded their app as well, upgraded the zpool...

Solaris scales

This is a nifty small feature. Tools like ps , df , du , ls , ps , size , prstat and swap now have the option --scale . This makes the output of those tools...

Free the spare pönökels of the world - now!

I'm getting a new bike soon. Of course you want to use a number of old components as well. A bike is pretty expensive right now as everyone prepares to evade...

Small changes: New open files default.

In a relatively recent Solaris 11.4 SRU a limit was increased in its default setting. In 11.4 (no SRU ) the limit of open files for a user was 256. ```...

Solaris 11.4 and user_reserve_hint_pct

Piped sandboxes
