How to Use the ss Command (Linux Crash Course Series)

[@wyldfiregames]

My first thought was, 16 years supporting Linux systems, all command line, and I've never heard of this command. Then I started watching and was like, isn't this just netstat. I'm glad someone below mentioned it's a new replacement for netstat. Thanks for the video, succinct and covers the important stuff. You got a new subscriber.

iproute2 was there in 1998, ss is from 2004.

[@Jaabaa_Prime]

Nice CLI summary. Another really useful one is "sudo ss -ltp" -> Which process (-p) is listenening (-l) on which TCP (-t) ports

[@rephlexc]

oh, i like this one too.

[@vk2amv]

I use ss -lntup all the time with my work. Normally the second command I run after ps -auxwf if I am trying to troubleshoot a service not responding on a server.

[@willrun4fun]

Somehow I've never heard of this command in the past 25 years.

[@Jaabaa_Prime]

It replaces "netstat"

[@Ali4s-321]

I thought that the last time the ss command was used was in Germany in 1945 🙈

[@provocativecheesecake]

@@Ali4s-321That was awful. I approve.

[@sauraabh]

And I thought I was the only one

Great quick howto for the ss command. Learned lots. Took notes. Ran it on Ubuntu 24.04.1 LTS on a new Linode instance. Got same results except for some stuff that leads me to other questions about 24.04 that I will research.

[@peterjansen4826]

A program/command which I never use, nice, I can learn. By the way, I will share this playlist with LInux-novices.

[@jamessmith4229]

Clear and concise. Thank you.

[@Ju13n1s2e9]

Now it is wroted down into my Linux dictionary - using the very useful Cherrytree app for having control on that.

[@friedrichdergroe9664]

Very informative. Thanks.

[@Parendinate]

Thank you its an amazing tutorial!

[@maxwellsmart3156]

I started using Linux in '94 and now when I want to spin up a quick Linux instance I feel like ripping my hair out when doing network config or anything else and I get 'Command not found'. I might go back to Slackware. Nobody thought about throwing in an alias or wrapper so the intermittent old guys could fade away gracefully.

[@toddratson7526]

I feel your pain. I miss the days when you configed an ip and hostname and f'ing computer would keep it till the end of time.

[@mariusstark]

You are outstanding at explaining even the small details. I really like listening and learning from you about linux in general. Can you make a video about hyperland in Arch Linux?

[@CaribouDataScience]

What about uucp?

[@mathieuberthalay21]

Thank you for your video 🤩

[@AliensInc.]

Ah nice, thinlinc used this for years

[@EmperorTerran]

good stuff but for people who dunno it ti will be lost in a vacuum, needed some practical example. Like you want to spin a minecraft server using docker and crafty and when you run it you get message that port XXXX is already in use, or better example is pihole and you get message that port 53 is in use.. well darn it who uses port 53, how do I find out? sudo ss -tulpn | grep 53 oh what do you know,, systemd-resolve

[@emmanuelulu5878]

Thanks

[@jeffshowalter7]

ss -tulpn

[@clementihammock7572]

How does it compare to "lsof"?

[@ronm6585]

Thank you.

`ss -s`: Total: 2259 - TCP: 1193 (estab 925, closed 215, orphaned 5, timewait 213). That's a lot of connections :/ Makes me feel uncomfortable.

[@avinashsridhar7124]

the ss commands you.

[@s.p.sanjay4253]

Sir could you tell me ,how to become a linux administrator, which topics i mainly focus to learn from scratch in Linux....

[@eightsprites]

Learn networking. And how to install/update linux. Both used for server work.

[@s.p.sanjay4253]

@@eightsprites thanks bro

[@Easymoney778]

Try this book bundle, has basically all you need to learn Linux for a super good deal

[@Easymoney778]

Great low-cost bundle for learning Linux, crazy amount of value for a relatively low price

[@kamurashev]

Cool

[@uuu12343]

This apparently was a thing. I'm ashamed I never knew about this

[@uuu12343]

Oh this is basically an official "tcpdump", representing "socket statistics", interesting

[@Rai_Te]

Just my 2cts ... #1 I had added, that 'ss' is the replacement for the older 'netstat' command from the net-tools package that is no longer installed by many distibutions. #2 is more an cosmetical thing ... light grey characters on black background in your terminal screen is not really easy to read. May be you personally like this color-combo ... however to produce youtube content, you might consider to use a combination with more contrast ... I might suggest to you the use of black characters on white background ... we use this combination as a mandatory setting for all teams/zoom/etc meetings where someone is presenting something using a terminal session. (No more complaints since we moved to that).

[@CommanderKappa]

Does this command commit unspeakable atrocities in eastern europe?

[@thetenthplanet]

No explanation of what the output means and how to interpret it. That felt like a rushed video, Jay. Not your normal work.

[@SearchFinger]

It was not so useful as it was not explained what those columns of figures mean. smh

[@johnhawthorne5848]

This video doesn't contain much more than glancing at the man page. It also contains far too much intro, sponsorship info and merchant info. Waste of time.

[@GooogleGoglee]

I mean, making a video on something so simple that can be found in documentation at first glance.... Such a waste of resources and time.

[@ohwow2074]

That's a very shallow argument. I for instance had never heard about this command.

[@GooogleGoglee]

@@ohwow2074 good for you

[@Jaabaa_Prime]

To read it in the documentation you first gave to know of it's existence. Many experienced users use the "old" commands, like netstat, ifconfig and nslookup. Not knowing that ss, ip or dig even exist.

[@GooogleGoglee]

@@Jaabaa_Prime I am not experience but I am experienced enough. This command is a must since netstat and others are not recommended. So basically the concept here is that Linux and Unix are systems where you are supposed to be curious, read documentation, and get your own experience. If you didn't know about 'ss' then you are not one of those. Again the specific approach is bad. After all a video will never tell you enough. If you feel touched by what I said, don't. It is not directed specifically to you

[@GooogleGoglee]

@@ohwow2074 good for you!

[@natural_stupidity_]

Would have been more useful if you had explained the output a bit, like what each column is showing. Good helpful video though.

[@whywhyzeemark]

The output varies a bit depending on your lab setup for any given day.
