Win10 shell has ssh? Oh boi, let's try that out.
> help ssh
This command is not supported by the help utility. Try "ssh/?".
> ssh /?
ssh: Could not resolve hostname /?: Name or service not known.

😲🔫

A few years ago I was browsing Bash.org, and a user posted that he'd physically lost a machine.

A few weeks ago, I'd switched my router out for OPNSense. I figured it was time to start cleaning up my network.

Over the course of tracking down IP addresses and assigning statics to mac addresses, I spotted an IP I didn't recognize.

Being a home network, I'm pretty familiar with everything on the network by IP, so was a little taken aback.

I did some testing, found out that it was a Linux box. Cool.

I can SSH into it. Ok.

Logs show that it's running fine, no CPU/Memory/Harddrive issues. Nice.

So where is it?

Traceroute shows its connected directly to the router... Maybe over an unmanaged switch...

Hostname is "localhost"... That's no help.

I've walked the network 4 times now, and God knows where it is.

I think maybe I'll just leave it alone. If it ain't broke...

Attempting to access my colleague's NFS directory on his VM, don't know the VM's IP address, hostname or password:

- 2 minutes with nmap to narrow the possible IPs down to ~30

- Ping each and look for the one with a Dell MAC prefix as the rest of us have been upgraded to Lenovo. Find 2 of these, one for the host and one for the virtual machine.

- Try to SSH to each, the one accepting a connection is the Linux VM

- Attempt login as root with the default password, no dice. Decide it's a lost cause.

- Go to get a cup of tea, walk past his desk.

- PostIt note with his root password 😶

FYI this was all allowed by my manager as he had unpushed critical changes that we needed for the release that day.

When your co-worker asks for a more memorable hostname for the next dev cluster...

I'M BACK TO MY WEBDEV ADVENTURES GUYS! IT TOOK ME LIKE 4 MONTHS TO STOP BEING SO FUCKING DEPRESSED SO I CAN ACTUALLY STAND TO WORK ON IT AGAIN

I learned that the linear gradient looks cool as FUCK. Honestly not too fond of the colors I have right now, but I just wanted to have something there cause I can change it later. The page has evolved a bunch from my original concept.

My original concept was the bar in the middle just being a URL bar and having links on the sides. If I had kept that, it would have taken me a few hours to get done. But as time went on when I was working on it, my idea kept changing. Added the weather (had a forecast for a while but the code was gross and I never looked at the next days anyways, so I got rid of it and kept the current data). I wanted to attempt an RSS reader, but yesterday I was about to start writing the JavaScript to parse the feeds, then decided "nah", ended up making the space into a todo list.

The URL bar changed into a full command bar (writing the functions for the commands now, also used to config smaller things, such as the user@hostname part, maybe colors, weather data for city and API key, etc)....also it can open URLs and subreddits (that part works flawlessly). The bar uses a regex to detect if it's a legit URL (even added shit so I don't need http:// or https://), and if it's not, just search using duckduckgo (maybe I'll add a config option there too for search engines).

At this very moment it doesn't even take a second to fully load. It fetches weather data from openweathermap, parses it, and displays it, then displays the "user" name grabbing a localstorage value.

I'm considering adding a sidebar with links (configurable obviously, I want everything to be dynamic, so someone else could use my page if they wanted), but I'm not too sure about it.

It's not on git yet because I was waiting until I get some shit finished today before I commit. From the picture, I want to know if anyone has any suggestions for it. Also note that I am NOT a designer. I can't design for shit.

Germany is a nice place, but sometimes the bureaucracy is a bit much.
Especially when you try to write them a nice mail that you can't come to their "mandatory" appointment.
Because you're sick, like every damn time during the autumn holidays.
An email to an address where the hostname doesn't even exist. WTF?

Also don't you think that address is a bit too long? Chances for typos are pretty high when you do that, you know?

ssh root@hostname

My colleague and I have been trying to setup a VPN server for devs who wanted to work from home. We asked our sysadmin (who's in another office in another country) to try connecting to the server. She replied after a while that she was unable to connect. We then asked her what port she tried connecting on and she replied, "No, I didn't use any port. I am connecting directly using the hostname".

Sometimes I have to work with physical hardware. There are over 300 machines in our lab, split among two subnets. But for some reason, I can never access my machines by hostnames.

Every other week, there's an IP conflict on this network, requiring me to log into the active directory server and delete old DNS entries. This usually happens because someone decided to deploy 64 VMs on a huge server, all at once, didn't boot them with a delay, let alone with with a warning to IT.

Then when my superior asks how my progress has been and I respond with "I can't even get the machines to ping each other by hostname, there's something wrong with the DNS:, I get the following response: "HOW COME NOBODY ELSE IS HAVING PROBLEMS WITH THIS. YOU'RE FULL OF SHIT", from someone who spends 90% of the year abroad, working remotely.

For the last 20 years, there's one thing I've not been able to do reliably:

Share a folder on a windows computer.

Why the fuck can I write /etc/smb.conf from scratch with a blindfold on and make it securely work from all client devices including auth & acl, but when I rightclick and share on windows it's either playing hide and seek on the network (is it hiding behind //hostname/share? No? Maybe in the bushes behind the IP addresses?), or it's protected by mysterious logins requiring you to sacrifice two kittens a day.

Yes, finally it works! One windows update later... aaaand it's gone.

JUST GIVE ME A FUCKING CONF AND A MAN PAGE, MICROSOFT. I DON'T CARE THAT YOU'RE ORALLY PLEASING ALL THESE MALWARE RIDDEN GUISLUTS ON THE SIDE, JUST GIVE ME A FUCKING TEXT FILE TO STORE AND EDIT.

I just love it to giggle at "hackers" in movies/series.

"He used an ARP to 'crack' the hostname of the server"
And then a countdown when the Server is hacked...

Back when I started my career (12 months ago lol), I was in IT support. Having to deal with people who have hard times locating and reading off a sticker, let alone telling me their IP adress, only to realize it's the whole store that's offline, not only their PC (gosh do they ever talk with each other). So I decided to code a small tool that shows your hostname and IP adress, and pings the router, firewall and Google DNS. Aaand just in case the number for the IT hotline. Plan was that we could just tell them to double-click on that one icon on their desktop and read out what it says. We deployed it and I was happily waiting for it's time to shine (still a trainee I was also kinda proud of it), but when the network engineer found out, he wasn't happy about it at all. He was afraid too many people would open that new tool without us telling them to do so and/or forget to close it, producing a number of pings to the router, firewall and google. He went on about Google maybe blocking our IP if we produce too many pings and so on.
In my opinion he was kinda overreacting, but he wasn't that wrong and is a nice guy and responsible for our network, so we recalled the tool and never actually used it.

I'm changing a hostname, not taking out a loan.

The hostname for my server that is running RancherOS is "huevos"... I thought it was funny

Well, being the only one in the house who can really solve computer problems:
We have a home nas in our network for filestorage and since a few weeks, we couldn't acces the device through windows explorer, so today I went on a exploration... First I tried the nas in a seperate different network, and it worked immediatly! oke great, try it in our main network again. And 'ofcours' it's not visible. So I go to the router webpage, and the page of our router just really sucks! So it was quite hard to find out if the NAS was attached or not, ad if so, under which IP. Finally found that, tried to connect to the webpage of the NAS, but got a timeout, ping would timeout too! I thought that that might have someting to do with that the NAS would connect via static IP. So I changed that to a dynamic IP, and I could atleast get to the website. After that I could try all the services and all of them worked perfectly, except for samba... And samba is the only service we actually use, so after that I thought that the device not showing up in network view in explorer had something to do with that the nas wouldn't show me a hostname in the router. So I tried to fix that, after an hour of trying to get the hostname to showup in the router, I just thought that I might try to connect to the nas via the IP. So I found via SO that I could just use //192.168.0.104 and I got into the samba server. So I guess that it was actually working all along 😒. After that I didn't want to bother to work with the hostnames, so I just gave the NAS a fixed IP, made a few shortcuts for my housemates and now it all works again.. For now at least...

Had trouble to connect to our MySQL database, so I decided to open a ticket to the Database admins. At least they are pros and I'm sure they'll help me:

"Hey guys, I have trouble connecting to [Hostname]. I guess it's a firewalling issue would you take a look? Attached are screenshots, saying hostname not found.

Answer:
Hey Dominique, are you sure the password you used is correct? Is it yours or the sysuser pw what you sent to the server? How did you send it?

Me: (kind of confused) Hey dear admin, did you look at my error message? It says Hostname not found. What do you think how I provided any credentials?

Support: yes, I saw your screenshot and don't see any password entry. That's why I asked!

Me: Well, than... ok... go and search for another job. Yeah and consider fucking yourself. Kisses.

Made this one-liner today:
hostname $(curl nsanamegenerator.com | grep body | sed -e 's/<.*;//g' | sed -e 's/<.*>//g')
and added it to my laptop's crontab...

Fun story:

I once was in some kind of SSH-ception, my machine and two remote machines where the same, as in the username and hostname (local name) where equal. All with and Hitachi 500 GB disk.

I was going to nuke the remote machine 1, so later that day I would rebuild the system and all that good stuff, so it would be equal to remote machine 2.

I check the disks and see that it is what I expected, and proceed with the so called "sudo rm -rf /".

Turns out, in my madness, I was doing this on the remote machine 2, not on remote machine 1 (too many terminals), and after I pressed the button and 5 minutes are passed, I realize my mistake...I had just killed a big part of some research I was doing for college (100 or so simulation files, 2GB each).

LESSON: Always triple check your drives and sessions.

P.S.: Something similar happened with me once doing dd to make a ubuntu bootable flash, I ended up erasing 800GB of backup files.

Spent three days banging my head against my desk trying to get an AWS Lambda function to work, only to finally discover that my code was perfectly functional and it was a security group problem. It was supposed to send a POST request to a load balancer's URL but couldn't resolve the hostname because the security group blocked a necessary outbound port for DNS requests.

That's what I get for not troubleshooting at the infrastructure level when experiencing connection issues. I did not spend two years doing tech support just to forget basic troubleshooting steps now that I'm in the DevOps field...

Goddammit,
today, my laptop crashed while shutting down.
I just switched it in again, and boom, Hostname-Resolution isn't working anymore.
I also already checked UFW, iptables and the hosts-file.
Guess I'll reinstall it tomorrow.

Set up customer's e-mail addresses in Plesk. Worked fine in testing, all goes well for about a week.

Then their e-mail stops delivering. Stuff arrives, but outgoing messages either bounce or fail silently altogether. I contact 1&1 support, and they help set up SPF and DMARC on the domain, and then we wait and see once the DNS changes propagate.

Well, something about these changes caused my business e-mail (on a separate server) to exhibit the same problem now, when it had been working for 3 years without issue prior to that.

Check back with 1&1 2 days later to see why the first one isn't working; we verified all of the records across everything, tweaked a couple other things (like setting the full hostname in Plesk to mail.servername.com), and waited 2 more days.

Still having the same problem on both accounts. did a bit of looking up the issue for Plesk and found that in order for SPF/DMARC to work, they have to be activated on the Plesk-wide mail settings, and then again individually at the domain level.

Made these changes on my business e-mail's server and domain and it fixed the problem!

Made the same changes on the server with the customer's domain and...still seeing the same issue.

Have checked all settings between them and they're identical. All the appropriate DNS records are in place. I'm kind of at a loss for waht else to check at this point.

How would you approach choosing a fairly short but meaningful domain name? Common words are obviously going to be taken.

I have a handful of domain names used for different things, but my main one is 17 characters long and made up of 2 words and not particularly interesting (my surname + another word). It's relatively easy to read out to people over the phone, but inputting it in a phone handset or on a device without a keyboard (e.g. setting the hostname + domain of a media centre with a remote control) is a bit tiresome.

Doesn't even have to be something I can say easily as I mainly want it just for "infrastructure" purposes rather than to host a website etc.

I'd probably use it for sign-up e-mails to reduce the amount of spam/newsletter mail (I do generate a separate address for signing up to most services) but other than that wouldn't be using it regularly for e-mail.

But I don't want something meaningless like abcxyz.

Here's a quickie that grinds my gears.
When a piece of software asks me for the a hostname but expects a fqdn and when the bloody thing automatically fills in a fqdn into the hostname field!

doesmyheadin.my.domain

HOSTNAME = doesmyheadin
DOMAINNAME = my.domain
FQDN = doesmyheadin.my.domain

If I'm wrong about this I fully accept it, but these are the standards I've been using which to me make perfect sense!
Bloody nonsensical bullshit modifiers.

I hate windows man. But I needs it for me games. I just wanted go set up my gaming rig to work double time as a nas. I set up a hostname and all for it but I can get it to be recognized by other device even on the same network.

So I was writing SaltStack state for syslog management and I had a simple config file in place to be deployed on a test server. I was writing the command to run the state for the test server, and the only thing that was left was to type the hostname of the server (instead of wildcard) when someone interrupted me. After I got back to this terminal I instinctively pressed return sending test configuration to over 80 production servers. Nice one...

Hi, so I am fairly new to GitHub and I just wanted to know how do you publish your code on GitHub Public Repo without disclosing your sensetive credentials like DB hostname, username and password, and other keys like Recaptcha secret?

My GitHub repo is connected to Heroku hosting so I cannot replace the keys with something dummy. It will fuck the production deployment up.

I just set up my pi as a test webserver to play around, any ideas for a cool hostname?

Hello everyone,

I've got a somewhat special issue with my setup.

I am running an instance of `lucaslorentz/ caddy-docker-proxy` as proxy that handles certificates and request and proxies them to docker containers that run `abiosoft/caddy:php` to host Laravel based applications. The problem is, that the `abiosoft/caddy` containers do not know it's assigned hostname and thus Laravel's `asset`, `secure_asset` and `url` respectively `secure_url` don't work as they use the internal hostname which would be an IP address and thus requests go to 192.168.240.x instead of example.com.

I am not yet entirely sure where I should tackle this problem and am grateful for every hint.

I am currently also evaluating traefik instead of Caddy-docker-Proxy and Caddys v2 official container instead of abiosoft's Caddy v1 container but I guess, that this wouldn't solve the issue as the container still wouldn't know that it's given Domainname is example.com
