Various services have existed, such as portmap(8), though NFS and similar services have often suffered from the "too complicated to debug" problem where devops (then sysadmins) would try turning the system off and then back on again in the hopes of resolving the issue du jour. You might get lucky and determine that node number three (of many) was cursed and leave it switched off for the Season of Mammon, more commonly known as Christmas, and to retire it quietly, later. Hypothetically.
Generally host and port mapping gets shoved somewhere into the configuration management layer and hopefully does not become too complicated (or have too many security holes) as this could vary from "configuration files and a few scripts" to database and services layers that few can debug, especially not a sysadmin at 3 AM in the morning running on an hour of bad sleep. Hypothetically.

i chose gopher port just as an example. try with any other service name mapped to a port number from /etc/services and the result will be the same. the OP's goal was to use many http/https services, so we are talking about many http(s) services.

Sure, but they are running web-apps they've vibe-coded (hence the .vibe tld) and for that use-case of many web apps that I run in docker containers I use nginx-proxy [0]. All the container needs is a VIRTUAL_HOST environment variable with the domain and what my router needs is an address entry for the wildcard subdomains. I even have nginx-proxy on a internet-accessible staging server.
If the port number space was bigger, I wonder if we would have gotten a global naming service (ala DNS) for unique service names.
You can still publish port numbers along with addresses in DNS though (SRV records).

URLs already have default ports for service names as a feature.
http:// means port 80 unless specified otherwise
https:// means port 443 unless specified otherwise
ftp:// means port 21 unless specified otherwise

...
The practical solution for TFA is actually just an nginx server running on port 80 with proxy_pass
HTTP 1.1 and later will have the browser supply the domain name that was used to access the site, and even though *.localhost all resolve to 127.0.0.1, nginx will pluck out the correct configuration and proxy_pass the correct one.

The file /etc/services maps names to port numbers, like /etc/hosts does for hosts.
E.g. "telnet localhost ssh" takes you to port 22 (not the default 23 for telnet). This works because /etc/services maps "ssh" to "22".
If you're sick of remembering port numbers, create some entries in your /etc/services.
Of course, only programs which use getservbyname to resolve port numbers will accept your names.

We’re discussing a tool that is designed for – and is only capable of – routing traffic to localhost. It’s perfectly reasonable to point out that there’s an easier solution for this use case.
example.com, and the reserved TLD ".example", exist for technical documentation and writing. If you are writing a comment on HN, or a curriculum for a networking class, then you can discuss "foo.example.com connects to bar.example.com" or "Let's hypothesize about two offices called accounts.example and human-resources.example"
The "example" domains are never supposed to reflect anything that is actually deployed onto LANs, or test labs, or the Internet, current situation notwithstanding.
There are, likewise, IPv4 and IPv6 ranges that are reserved to be used in documentation. Not the 192.168.0.0/24 or 10.0.0.0/8, but separate ranges that writers only write about, and are never deployed, not even in private.
And there's also .local for mDNS on local network!
I've also come across projects using a public DNS record that points to 127.0.0.1 (something like localtest.me?). IMO that's way worse than using .localhost since you're trusting some rando not to change the DNS records and exfiltrate your meant-to-be-local traffic.
ButlerianJihad 11 hours ago [-]
I did not mention .local, because it is covered in the linked articles: a special-use TLD, reserved for a certain purpose. It has often happened that LAN admins try to name something under ".local" and configure a zone for it in their BIND server. But this is incorrect, because ".local" is already managed by the zeroconf/mDNS protocols. It is a special case; and that is what ".internal" seeks to rectify, by giving y'all a TLD that can be truly internal and truly a zone under DNS server control, whatever that looks like for you.
".vibe" is not a TLD. It is not a registered TLD; it is not a reserved name. It isn't a domain at all. Go ahead, do a WHOIS lookup. Anyone who attempts to use such gibberish, even in documentation, deserves to be rudely surprised, someday in the future.

I've used[0] `.local` to achieve something like this, by advertising service endpoints over mDNS.
Exposing random services to your local network is exactly what mDNS is for, I always thought it was a shame more dev tooling didn't do that.
I know it's mixing of layers, but I can't help but feel the IPv6 transition missed the boat when they didn't just get rid of ports in the process. They've changed so much else anyway.
Want to run another webserver instance or whatever on your computer? Get the OS to allocate a new IP for it. Ports be damned.
Could be implemented in a backwards compatible way by requiring all IPv6 TCP/UDP traffic to use a fixed port number.

ipv6 packet does not have any port field. ports are on the level of tcp and udp, and you don't have to use tcp or udp on top of ipv6. ipv4 packet does not have any port information as well.

tcp6 is a thing though, was created at the same time as ipv6, and it does have ports, along with udp6. But if you really want one ip per stream and just hardwire port 1 or something, it's not like IPv6 does anything to stand in the way of that. Mght have performance issues on some OS's binding thousands of IPs to one interface, but that's on them to fix. Bigger lift would be the APIs that would need to change to manage whole prefixes at a time instead of single IPs.
magicalhippo 11 hours ago [-]
> ipv6 packet does not have any port field
Yes, that's why I said I know it was mixing of layers.
However ports are a layer violation in a strict sense, introduced as a workaround because there was no easy way to just add thousands of new IPs to a single host back in the IPv4 days. No need to continue a workaround that causes grief on a daily basis.
allarm 4 hours ago [-]
What do you mean? You’ll still have to use TCP or UDP over IPv6, and both of those protocols use ports. Nothing is stopping you from creating a transport protocol that doesn’t use ports if you want to, but that has nothing to do with the network layer.
magicalhippo 3 hours ago [-]
I mean that to connect to a service you wouldn't need to know the port, the IPv6 address would be enough.
This is why I consider ports a layer violation of sorts. You never talk to a machine with TCP/UDP, you talk to a service on a machine. And so as it is the full address to the service isn't just the layer 3 address.
As I mentioned this would be especially interesting when hosting multiple services, same or different, on the same machine since there would be no port conflict.
absynth 9 hours ago [-]
Conceptually its doable on linux and ipv6. Have the listening program sit on that default port of 80.
Something involving socat, an any-IP / TCP routing rule, a VPS or other machine with a ipv6 /64 and plenty of duct-tape.
You'd get an application sitting on port 80 accessible via some unique ipv6 address (in the /64) on a tcp port 80. They needn't be the same port number but it would make it easier.

I think this product demonstrates the atrophying of thought that results from too much LLM usage: design was obviously a long back-and-forth with a sycophantic LLM.
I find out what all my local servers are by `cat /etc/hosts`, because I put them in there. They run using an entry in the nginx config.
For short-lived stuff I don't even bother with that, I just use `whatever.localhost`.
If there was no LLM, author would have put a little more thought into this, maybe did a google search, and realised that all he needed were two shell scripts.

The interesting part to me isn't the port numbers, it's the automatic service start/stop, including idle route shutdown.
Why not resolve everything with UNIX sockets instead, that way you can have them named and scoped instead, hiding behind port 443, since it's mosly HTTP anyway.

Also, a service port is always qualified by its protocol. There are separate port namespaces for each IP protocol that uses ports. "8483" is not a service port, until you spell it out:

It always fascinated me that ports don't have any kind of textual resolver, so you can bind to `:1234` and also say "please also accept `:foobar`".
But that would itself require some kind of "port resolver" on a device, and that's another service to break and fix :)

system2 15 hours ago [-]
It is funny, I just built something like this last week and named it "Network". Additionally it scans for any type of data packages arriving at the SonicWall and sees if they are approved by me or not. I am paranoid after using TP Link at home like a dumbass.

I am very out of the loop. What is wrong with TP Link? What are the risks with it?
Just search for "TP Link ban", you will see a lot of news. I switched to SonicWall + Ubiquiti + my own monitoring software to be safe. I should've done it years ago, but I was lazy.

This is a neat approach. One thing I wonder about is how it handles services that use the same port number across different protocols (like 443 for both HTTPS and SMTPS). The /etc/services file approach has the same ambiguity, but at least it lists the protocol alongside the port. A lookup table that includes protocol would be more robust for mixed environments.
Generally host and port mapping gets shoved somewhere into the configuration management layer and hopefully does not become too complicated (or have too many security holes) as this could vary from "configuration files and a few scripts" to database and services layers that few can debug, especially not a sysadmin at 3 AM in the morning running on an hour of bad sleep. Hypothetically.
also `curl -v http://127.0.0.1:gopher/` gives error message
so the ports are named, it is nice, but in practice it does not make life easier.is it http or gopher? :)
i just wanted to make the point that even if you have service names in /etc/services, it is not possible to use that names easily to host/access http(s) services.
nc is for generic connections and handles it well.
if you host an http(s) service on port 11111 you can reach it with url http://127.1:11111, but url http://127.1:vce/ would not work in most software.

You can still publish port numbers along with addresses in DNS though (SRV records).
http:// means port 80 unless specified otherwise
https:// means port 443 unless specified otherwise
ftp:// means port 21 unless specified otherwise
sftp:// means port 22 unless specified otherwise
...
The practical solution for TFA is actually just an nginx server running on port 80 with proxy_pass

It's never.
After decentralisation we always see decentralisation. After a period of growth, a decline will follow. After the vibe coding hype, consolidation will follow. After rain comes sunshine.
People shit-talk container orchestration systems like Kubernetes, but if anything they greatly simplified (if not completely eliminated) the need for this sort of network bookkeeping.
Your comment unironically is something I prefer and one of my biggest pain points with Linux.
As a newb, I'm sure there's something called with a mycommonproblemd name that has a stateful interface. But sometimes that all adds up to make things feel complex. And it let's me make stupid mistakes, like I forgot to close or open a port on firewalld, or I disabled a container but forgot to commit a change to my systemd units.
It's nice to just have a nice file called myservice.nix that tracks the firewall port, name, systemd startup and update scripts.
Way more often it’s developers who can’t figure out that their http library only supports 2 concurrent connections, or emit garbage/malformed log lines and then bitch that they can’t see their app logs because we dropped them, or can’t be fucked to do “kubectl describe” in their own developer namespace that they have full permission for.
If you truly experience issues with just using YAML then you need to skill up probably.
But go ahead. /etc/services, please, share with me how it's setup to do thing likes create the HTPS and makes it trusted and sets up the domain. Go ahead.
Go ahead. You can ONLY use /etc/services.
Or, you are admit you don't actually have a clue as to what /etc/services does.
E.g. "telnet localhost ssh" takes you to port 22 (not the default 23 for telnet). This works because /etc/services maps "ssh" to "22".
If you're sick of remembering port numbers, create some entries in your /etc/services.
Of course, only programs which use getservbyname to resolve port numbers will accept your names.
i dont know why people keep insiting on that file while there are perfectly fine commands to pull from your boxes what is holding what port.
that is all besides the point though if you look at what you should be doing and keeping all this information in some kind of asset management system from which you can deploy things (which is kinda what k8s and docker etc. try to do (miserably)).
unless you are binding stuff to random ports on random boxes there is no need to do any of it at runtime and you can just consult your bookkeeping (for which etc services lacks a lot of details to use...)
And that none of us can get bothered to "Google" if a thing that does the same thing already exists. Currently vibing, on a train, a spaced repetition thing for my kid - because I needed a specific list of countries - and its faster to create the whole app rather than figure-out how to find one that would do this.
anki?...
https://portless.sh/
Example from the website:
- "dev": "next dev" # http://localhost:3000
+ "dev": "portless myapp next dev" # https://myapp.localhost
That would work if your goal was to route traffic to localhost.
What if it isn't?
There are reasons why the likes of example.com exists.
> So I built local.vibe — a friendly dashboard and local .vibe hostname for every local web app on your Mac. No more localhost:3000 vs localhost:5173 roulette.
> The whole thing communicates over a Unix socket acting as a reverse proxy. No external services, no accounts, no telemetry.
We’re discussing a tool that is designed for – and is only capable of – routing traffic to localhost. It’s perfectly reasonable to point out that there’s an easier solution for this use case.
example.com, and the reserved TLD ".example", exist for technical documentation and writing. If you are writing a comment on HN, or a curriculum for a networking class, then you can discuss "foo.example.com connects to bar.example.com" or "Let's hypothesize about two offices called accounts.example and human-resources.example"
The "example" domains are never supposed to reflect anything that is actually deployed onto LANs, or test labs, or the Internet, current situation notwithstanding.
https://en.wikipedia.org/wiki/.example
There are, likewise, IPv4 and IPv6 ranges that are reserved to be used in documentation. Not the 192.168.0.0/24 or 10.0.0.0/8, but separate ranges that writers only write about, and are never deployed, not even in private.
localhost is only ever going to be the loopback interface, never across a network: https://en.wikipedia.org/wiki/.localhost#Conventional_use
See also: https://en.wikipedia.org/wiki/.test
The latter article lists foreign-language TLDs which serve the same purpose.
Some proposals are described here: https://en.wikipedia.org/wiki/.home
I've also come across projects using a public DNS record that points to 127.0.0.1 (something like localtest.me?). IMO that's way worse than using .localhost since you're trusting some rando not to change the DNS records and exfiltrate your meant-to-be-local traffic.
As for 127.0.0.0/8 in the public DNS: https://utcc.utoronto.ca/~cks/space/blog/sysadmin/HowNotToDo...
As for localnet and localhost in general:
https://utcc.utoronto.ca/~cks/space/blog/sysadmin/LocalhostI...
https://utcc.utoronto.ca/~cks/space/blog/web/LocalhostSurpri...
".vibe" is not a TLD. It is not a registered TLD; it is not a reserved name. It isn't a domain at all. Go ahead, do a WHOIS lookup. Anyone who attempts to use such gibberish, even in documentation, deserves to be rudely surprised, someday in the future.
Exposing random services to your local network is exactly what mDNS is for, I always thought it was a shame more dev tooling didn't do that.

Want to run another webserver instance or whatever on your computer? Get the OS to allocate a new IP for it. Ports be damned.
Could be implemented in a backwards compatible way by requiring all IPv6 TCP/UDP traffic to use a fixed port number.
Yes, that's why I said I know it was mixing of layers.
However ports are a layer violation in a strict sense, introduced as a workaround because there was no easy way to just add thousands of new IPs to a single host back in the IPv4 days. No need to continue a workaround that causes grief on a daily basis.
This is why I consider ports a layer violation of sorts. You never talk to a machine with TCP/UDP, you talk to a service on a machine. And so as it is the full address to the service isn't just the layer 3 address.
As I mentioned this would be especially interesting when hosting multiple services, same or different, on the same machine since there would be no port conflict.
Something involving socat, an any-IP / TCP routing rule, a VPS or other machine with a ipv6 /64 and plenty of duct-tape.
You'd get an application sitting on port 80 accessible via some unique ipv6 address (in the /64) on a tcp port 80. They needn't be the same port number but it would make it easier.

Your browser might be able find what you're looking for if you just type in the page title
Your dev stuff could just open the browser automatically when you start it
*.localhost is a Secure Context in Chrome and Firefox
I find out what all my local servers are by `cat /etc/hosts`, because I put them in there. They run using an entry in the nginx config.
For short-lived stuff I don't even bother with that, I just use `whatever.localhost`.
If there was no LLM, author would have put a little more thought into this, maybe did a google search, and realised that all he needed were two shell scripts.
The more you use LLMs, the less you actually think

The entire damn article is like this - why would I trust software to run on my local machine when it was written by someone who did not even take care writing a blog post? How much care would they have possibly put into reviewing their vibe coded slop if they couldn't even bother to review their blog post?
That seems to run orthogonal to this. The primary benefit I see here is not having to care at all what ports apps are actually starting on. Just run them, and access them by name. Same as a regular website on the internet where one doesn't care about the IP.
> How much care would they have possibly put into reviewing
Just enough to ensure that it works for them, which is what really matters. Others go in knowing that as well, and add/change that base to their own preference. That's the world we're now in.
If that's what really mattered they wouldn't have posted an article they didn't write trying to get traction on a product they didn't create from a userbase that doesn't need it.

Super simple. (although I use rewrites at my dns layer for the whole local lan, but whatever)
It also solves issues my password manager has with multiple services on the one host but with different ports, but putting each on their own 2nd level domain.
From a brief glance over the code I like the approaches I see. Using the `/etc/resolver/` mechanism is a new trick to me!
The interesting part to me isn't the port numbers, it's the automatic service start/stop, including idle route shutdown.
Not too long ago I had a similar issue and solved with that.

Granted no fancy UI to start and stop things but is it really needed?
Tbh this is not a single binary you need dnsmasq go and other things

I've been wanting something like this for local Dev, but I think more:
Per user DNS.
So if the process doing the lookup is my own then redirect to the named service.
For example, I had never heard about etc/services until 2 minutes ago
173 looks like ITE
5 in roman numerals is V.
If you type "8483" on T9, your phone may offer "THUD" or "TITE" or all three, as choices.
But with a normal telephone keypad, if you dial, e.g. "(800) 555-VITE" then you will always dial "8483".
https://en.wikipedia.org/wiki/Phoneword
Also, a service port is always qualified by its protocol. There are separate port namespaces for each IP protocol that uses ports. "8483" is not a service port, until you spell it out:
or or or etc.A TCP stream, for example, consists of a tuple:
I am also sick of handling port numbers - I end up allocating them on a schema to different services, so for testing I can spool any VM/service combination and avoid crossover. But if I want the same service twice, ah...
It always fascinated me that ports don't have any kind of textual resolver, so you can bind to `:1234` and also say "please also accept `:foobar`". But that would itself require some kind of "port resolver" on a device, and that's another service to break and fix :)
