I just had the most intense nerdgasm of my life.

So I'm learning NodeJS (11/10, super fun, totally recommend) and I already had a chat script written up but it was only available to my LAN. Im hosting it using my Raspberry Pi Zero, which is surprisingly fast, and obviously sips power. Anyways, I FINALLY figure out port forwarding (Comcast made things harder, as per usual) and for the first time in my young life, I chatted with someone half way across the country... Using the hardware I set up, running the script I wote, on the network I configured.

I could have sworn I was drooling.

Today was a good fuckin day.

Just moved, new room, let's try to setup port forwarding!

Well, i thought that too. Just spent hours trying to get this motherfucker to work. Tutorials, everything.

Every time that damn can't connect error. About to lose my shit.

Suddenly *hold on, is Apache installed on my new KDE Neon installation?!*

*oops* 😅

Okay, help :(

Trying to get my dns server in php to work from the outside (it's on a vm on one of my dedi's) but it's not working.

- Port forwarding works well: confirmed.
- Connection type: UDP; confirmed.
- I *can* dig from the host (dedicated server) to the vm.
- nmap scans show an open port.

The exact same happens on my local network.

I'm lost.

One of those things that put a smile on my face happened today.

I (like many devs) am fond of Linux. So I use Linux on everything.

I'm currently doing an internship abroad in Finland(Linus Torvald's country!) for my college.

So there is this Finnish student who uses Linux. And after a while he asked what I was using so I told him that I'm running linux(arch+i3 like all the cool kids).

So one day he was like; But can you game on Linux?
I was like, yeah sure, might not work as well as Windows but some games run native and some can be emulated through wine. He was like; Hmm maybe I'll try it out.

So he installed Linux mint on his laptop and came to work. I was rather proud (even though he installed the bastard child of Debian and Ubuntu).

So far I've helped him set up streaming games from his pc to Linux and port forwarding.

But then came the big boy. Since I always try to teach him some stuff since they don't teach him a lot at his school.

He asked me if I could help him set up a plex streaming server on Linux.

So we took an old computer and installed Ubuntu Server(Lot's of information for it).

Installed and configured plex server, qtbittorrent-knox and all kind of goodies.

I started showing him how to use ssh, how the rights system works, etc.

It broke my heart a little that he want to be able to teamviewer in it.(since it's running openSSH daemon)

So he installed Ubuntu's desktop ontop of it as well as teamviewer.

It ran slow as hell because the PC has an old crummy core2duo and ddr2 2gb of ram. It chokes when multitasking.

So seeing that as well as telling him everything that can be done with a GUI can be done in CLI.

I saw the lightbulb lighting up. He gets it now. He understand the power of Linux.

That just made me smile all the way home.

So I was setting up my friend's NAS. Got everything worked in minutes (dns, port forwarding etc.). Enabled ftp connection tried it locally, working. Tried remotely, timed out...

After half an hour I was about to tear my hair out one by one when he suddenly said to wait a sec he knows what's the problem. Tapped two on his phone and suddenly, it's working.

THE FUCKING PHOTO UPLOADING FROM HIS PHONE TO THE CLOUD BLOCKED ALL INCOMING CONNECTIONS AND HE WAS AWARE OF THAT ALL ALONG. WHAT THE FUCK MAN, DO YOU ENJOY SEEING ME STRUGGLE?? That was literally an "I'm out" moment.

After months of googling and troubleshooting my router settings trying to figure out why my port forwarding settings are not working only to realize that I'M BEING CGNATTED TO OBLIVION BY MY FUCKING ISP WITHOUT A FUCKING NOTICE!

y.

How motherfucking difficult can it be to port forward something internally?!

Forget about a missing semicolon. I was forwarding Neo4j to port 4747 and calling it in Asp.Net with port 7474 in Docker containers. It took me 6 hours to figure that one out. Lol, It's time for the weekend.

Port forwarding works well: confirmed.

Yeah... that felt awesome.

How the fuck do you do port forwarding on your Rasberry Pi without having to hack the NASA or subscribe to some obscure websites??? God fucking damn useless websites that can't agree on a fucking point

I was working on a thing at work which routes http requests from one endpoint and port to several local services.
I was halfway done when I noticed I just wrote a primitive reverse proxy.

Anyway, I'm calling it GRID, Gateway for REST Interface Distribution.

It's capable of dynamically attaching new routes and services and removing those during runtime via inbuilt typescript compilation service.

Each "runtime module" defines several routes which may have a middleware function (express.js style), which gets executed before forwarding the request to the local service.

I don't know why, but I'm kinda proud of this one; Feels like I made something actually useful for once.

Gonna maybe add a webUI with the monaco editor to write typescript modules without needing VSCode...

Also I may implement a load balancing system for scalability.

It comes with a cli too.

Gonna put it on github and post it here once I'm done with v1.

Who the fuck comes to the idea of printing the local IP address on the Fucking screen?

Yes, I know that it is not remotely accessable (only when there is no port forwarding set for that ip), but think of that this way: Someone manages to get in that network. Without scanning the network, you would have your first victim. You could analyzer the traffic of that victim and find more victims. And so on

So, I move house with my amazing, already configured and stable router with built in VPN, DDNS, Port forwarding and DHCP addresses.

Received ISP shitty router at new address and want to use as modem only, so I go read the manual.

"Bridge mode requires you to configure your other router with PPPoE and the ISP's credentials"

Landline is not working, so I cannot call the number to retrieve my password. After 2 days of waiting, engineer visits, installs master socket, dial tone yaaay.

Call number to get password, automated voice message has such a bad sound quality that I cannot figure out if it's saying F or S, and there are two of those letters.

Put ISP router in bridge mode, set other router to PPPoE and put credentials, nothing. Try with F and F, S and F, F and S, S and S... Nothing. Put it back to dynamic IP address, it works.

I resign myself and manually configure everything I had on the good router to the ISP one. A few issues with my server and DDNS, but hey, internet works.

Start missing the other functionality, try the password idiocy again. Nothing.

Next day, go to work, talk to a colleague that lives close and has the same provider: "I just put it into bridge mode and it worked".

Go back home, bridge mode on ISP router, Dynamic IP on good router, no credentials. It works.

Why do I always overcomplicate stuff?

guy taking one of my courses is wondering why bitbucket can't reach his local machine address at 192.168.0.13 😂

🤡

(and inb4 annoying rubes like sidtheitkid or whoever), in the lesson I CLEARLY explain the steps of local IP -> router -> public IP -> internet, as well as the port forwarding / routing needed

probably like 5 of you on this site anyway who actually understand routing, the rest argue about which is better, vanilla javascript or <insert framework of your choice here> yawn. i grow weary

farewell

A CTO who tells you to use web interface instead of cli (ssh) to configure port forwarding

More network/hardware than dev but anyway: I use OPNsense as a firewall at home on an embedded system. Had everything set up nicely and appearing to be working fine, quite a lot of things set up (static leases, VLANs with various firewall rules etc. - a fair bit of stuff involved). I noticed my remote system was failing to back up to my local one. Turned out port forwarding wasn't fully working (initial packet got through but nothing else). I noticed this at midnight.

Ran an update to see if that helped - nope. Reboot time then! It made its shutdown noises and I waited 15 minutes before giving up (no noises, no ping response). Took SD card out. Copied a fresh install onto it, thus wiping all settings. Booted up fine, set up my internet connection, all good. Proceeded to configure it. Noticed I couldn't access the internet from my PC, but could from the firewall itself. Rebooted the firewall. It didn't come back up. Argh!

Reinstalled AGAIN. Attached a serial cable and it was complaining about something which sounded like it couldn't read the SD card. Tried another. Nope. Looked online (using phone): known issue to do with boot delays.

Gave up and went to bed at this point (4am).

Next day: Installed it in a VM instead. Still no internet from my PC! Another known issue to do with default gateway not being the PPPoE interface. Got into shell, manually changed the default route. Was then able to update to the latest version which fixes the gateway issue. Rebooted the VM. All good.

Put all my settings back in, this time taking a backup afterward.

Only to discover....

....port forwarding wasn't working properly. Back to square 1.

Poked around with some NAT settings (outbound ones), made no difference, undid those changes and suddenly it started working.

WTF? /waves arms in the air

OPNsense folk were very helpful, producing a new build for me to try within a couple of hours of me asking about the problem.

But days like that, I start to question whether I really enjoy technology as much as I thought I did...

Has anyone worked with IP cameras? I just got a job for tech support for a company that deals with IP Cameras and they are going to have me doing network port forwarding. Any help and suggestion ?

I was trying to set up my own "cloud" for iot experiments. I planned to use Intel Edison with mqtt broker (using mosca) and a node js app for providing API for mobiles and browser. And also to do other book keeping.

I spent the half day trying figure how to expose these servers to internet.

I configured ddns in noip.com and ddns settings configured to it in my router.
Port forwarded to the local server services I needed.

And then tested. Worked perfectly on any device in my router connected network. Tested on mobile network. Bam! It fucking doesn't work.

Then connected another router.
Double port forwarded. Again worked perfectly on router network. And failed on mobile.
Tested if ddns is right. Did nslookup it was fine as fuck.
Then disabled port forwarding. Did dmz. Nope. Nadda. No luck.

Then scratched my head so hard that I lost more already losing hairs.

Then remembered about router hardware firewall. Disabled it.
Tested
And there it didn't work.
My dreams shattered like a fucking deer hit by car on highway.
Didn't work.
Then I see the IP pointing to my router in nslookup. Its 172.20.xx.xx. Its a fucking private IP.

My Asshole ISP is running another private network behind firewall. Which I fucking can't port forward
Now I think how much of a noob and idiot I am. Fuck this shit. Fuck all of these shit.
I am going for SaaS option for mqtt broker.
(Or help me?)
Once again.
Asshole ISP.
Fuck your firewall.
(PS: I had test the next day. FML)

I had the funniest thing today... So our company has some servers off somewhere in a VPN, as well as one server in our own office.

So, for simplicity, S1 is my own laptop, S2 is our office server, S3 is one VPN server, and S4 another.

I want to get a file from S2 to S4. S1 can SSH into S2 and S3, S2 can't ssh into any server, S3 can ssh into S2 and S3, and S4 can't ssh into any server.

So to get a file from S2 to S4, I took the path

S1 pull from S2 -> S1 push to S3 -> S3 push to S4

Part of it was preexisting keys meaning it was easier to send S1 to S4 via S3 than get my pubkey from S1 onto S4, but also S2 not being on the VPN meant I couldn't go straight from S2 to S3 or S4, so I had to route through S1, which I could add to the VPN (I'd sshed into S2 from home and thus couldn't put it on the VPN not to mention permissions, whereas I could put S1 easily onto it)

Twas certainly a fun time :P

Plus, port forwarding from a Docker container on S2 to S2's port to S1's port via ssh was fun to get set up.

Time to document this process :)

I want to do ssh is from outside the network. But I'm unable to do it. Very much frustrated. Has anyone tried it successfully?

Is there any way I can push a service to internet via something like p2p? My current internet is in a ip pool thus I cannot open a port to world.

Also I'm searching through internet too. Keep lmgtfy away now.

Not so tech savvy family member just asked for the router password to set up a network printer. I just hope they don't fuck up my settings (ip's and port forwarding and such) o_O
