peregus OP ,

Thanks, I didn't know that they could cost only 30€!

peregus OP ,

I don't need to connect my provider fiber, but my router (OPNsense) to my server.

peregus OP ,

Unfortunately there is no wavelength on the cable, I'll check the ONT

peregus OP ,

Regarding future proofing, I would say that anyone laying single pairs of fibres is already going to constrain themselves when looking to the future.

It could be right, but it depends on what people can run in the conducts. I was lucky to be able to pull those 2 cables.
On the other hand, this is a rent apartment that I will soon leave :D

peregus OP ,

I've checked on a forum and they say:

GPON adopts WDM to transmit data of different upstream/downstream wavelengths over the same ODN. Wavelengths range from 1290 - 1330 nm in the upstream direction and from 1480 - 1500 nm in the downstream direction.

So I guess that all the single mode SFP+ that have that range are ok.

peregus OP , (edited )

Do I have that right? If so, my advice would be to identify the wavelength of that fibre, which can be found printed on the outer jacket. Do not rely on just the color of the jacket, and do not rely on whatever connector is terminating the fibre. The printed label is the final authority.

You got it right!
On the cable unfortunately there is no wavelength printed (it's a cable made for my ISP), but I've read on a forum (that talks about this ISP):

GPON adopts WDM to transmit data of different upstream/downstream wavelengths over the same ODN. Wavelengths range from 1290 - 1330 nm in the upstream direction and from 1480 - 1500 nm in the downstream direction.

I think that I'll go with 2 SFP+ 10GBASE-LRM 1310nm 2km Module, Cisco that costs 29€

Edit: In the meanwhile, do you have any 2,5Gbe PCI card that you suggest (I need it to connect OPNsense to the ONT via PPPoE)? I've found only the QNAP QXG-2G1T-I225 that costs about 75€ or the Edimax EN-9225TX-E for about 41€ (but I haven't read much about this one).

peregus OP ,

Thanks for your precision!
To the ONT arrives a single fiber with a SC/APC connector, but this is not a problem since I will be using the ONT provided and use the 2,5Gb copper port to connect it to OPNsense (looking for a 2,5 Gb PCI card).
The 2 fiber that I've asked them to run (from OPNsense to server) are terminated with the same SC/APC connectors and I was thinking about using this SC female/female adapter and this SC/APC to LC cable that I've just realized that are still APC...I'll have a look if there are SC/APC to LC/UPC cables

As for that xcvr, please note that it’s an LRM, or Long Range Multimode xcvr. Would it probably work at 30 meters? Probably. But an LR xcvr that is single mode 1310 nm would be ideal.

Is it a LRM? Damn, I didn't realized since I've filtered for single mode. If the filter doesn't work, I've no idea which is LR. Would you be so gentle to point to a cheap one for single mode finer?

peregus OP ,

Although your ISP was kind enough to run this fibre for you, the price of 30 meters LC/UPC terminated fibre isn’t terribly excessive (at least here in USA), so would it be possible to use their fibre as a pull-string to run new fibre instead? That would avoid all the adapters, although you’d have to be handy and careful with the pull forces allowed on a fibre.

The problem is the installation of the connectors. They've welded the fiber the SC/APC pigtails, I wouldn't be able to do that.

The big manufacturers (Cisco, HPE/Aruba, etc) will have detailed spec sheets, so you can find the branded one that works for you. And then you can cross-reference that to cheaper, generic, compatible xcvrs.

That would be very very generous of you; in the fiber section I'm pretty ignorant and I'm worried to purchase wrong items 🙈

peregus OP , (edited )

Thanks a lot!
It seems that this from fs.com in the non Aruba compatible brands costs 32€
Thanks again!

Edit: And I've even found the LC/UPC to SC/APC cable!

peregus OP ,

Thanks for your reply, I really appreciate it!

peregus OP ,

Thanks for pointing me there. Although I couldn't find any.
I think that I'll go with the QNAP QXG-2G1T-I225

peregus ,

It's also possible to use Telegraf.
I use it on different machines that sends data to InfluxDB that are displayed with Grafana

peregus ,

If you'd like to sell a couple of drivers and you're in Europe, contact me.

Why do firewall rules need to resolve FQDNs?

peregus , (edited )

@kakes
It would be better to have the server on a separated VLAN

peregus ,

Sorry, but I still don't understand, what's the need for that?

peregus ,

What's the need of the public IP in the firewall rules?

peregus ,

I'm curious to know in which case is useful to know the public IP in a firewall rule because I've never used it.

peregus ,

To allow access from a friend you need his public IP, not yours.

peregus ,

Dude, just chill!
I didn't think that your answer made sense in the first place and that's why I've asked why you wrote that sentence. I'm not the one that reply to a comment saying "You're wrong!", unless I'm more than sure about what I'm talking, otherwise, and in this case I wasn't sure and I wanted to know your point.
I'm here to give my point of view and also to LEARN from others and this is why I kept asking you what was the need of resolving a DNS in a firewall rule, so that maybe I could start using those rules too.
On the other side, if you understood that your answer didn't make sense, you simply could have just said it and not waste mine and your time. I think that we ALL are here to share idea and knowledge and that NO ONE is perfect, me in the first place!

peregus ,

You've clarified your thought to a normal standard, as you didn't previously.
Learn to say "I was wrong" when you are wrong!

Edit: could I have said in the first place that I thought that you were wrong? Probably yes and I'll keep that in mind.

Nextcloud appreciation post

After months of waiting, I finally got myself an instance with Libre Cloud. I was expecting basic file storage with a few goodies but boy, this is soooo much more. I am amaze by how complete this is!!! Apps let me configure my instance to fit everything I need, my workflow is now crazy fast and I can finally say goodbye to...

peregus ,

I was surprised to know that there is no tool to pass from Nextcloud to AIO.

peregus ,

@neon_arch I think that a couple of lines explaining what websurfx is would be useful to a lot of users, instead of point them to another post.

peregus OP ,

I have the whole OS on that RAID.
Should I just create the new MD and copy everything there? I guess that I need to copy data when the OS is shut down (so with another PC), correct?

peregus OP ,

Oh, so easy?!
If the RAID rebuilds the disk, why should I install a bootloader? Isn't it already in the rebuilt disk?
By the way...hemmm...how do I install the bootloader? 😣

peregus OP ,

Thanks!

peregus OP ,

Got it, thanks a lot!

peregus OP , (edited )

Network Device Interface: basically it's an audio/video (and intercom) transmission over IP with low latency. The sender could be an hardware encoder or a software that I could install on a Windows VM and use on that machine Jellyfin and Netflix

peregus OP ,

Remove the PC connected to the TV (avoid turning on/off and fa noise) and watch Jellyfin and Netflix from a Windows VM on the Proxmox server.

peregus OP ,

Kinda, the difference is that you don't need to take the output of the graphics card (so no need to run X), but you can send the video directly from a software.

peregus OP ,

Because do this kind of thing is fun! 😁
And since I share the Netflix account with my siblings, I can only watch it on a PC (with Edge to have 4K 🙈).
...but I'll keep the Roku option in mind. Thanks

peregus OP ,

I've never heard of those, but it seems that are both software and I wonna get rid of the PC connected to them TV.

peregus OP ,

Those are all chinese non branded products and none of them support 4K (maybe not even 2K) ☹️

peregus OP ,

That's right! I have to try it, thanks!

peregus OP ,

Since I'm sharing the Netflix account with my siblings, I can't use a smart TV, a Roku or another player but just a browser, because the hardware players should all be using the same Internet connection.

peregus OP ,

Thanks, I'll look into it.
I've never heard of this moonlight/sunshine and I'm curious!

peregus ,

Is it possible to issue and update certificates for LAN services?
About wildcard certificates, is it possible with Let's Encrypt?
Thanks!

peregus ,

I'm using Cloud flare, I'll look into it, thanks!

peregus ,

What is useless?

peregus ,

In my opinion it's more useful than yours.
Is it missing some description? Sure!
Do I like posts like this one? No.

But instead of shouting your comment with anger, why not write something like "why not add some description? The way you posted it is pretty useless".
It may work for this time and for the others for the OP (and for the others that have read your comment).

peregus ,

120? That doesn't seem normal, what services were you using within NC?
Mine sits still with a load of 0. something.

peregus ,

Do you know if he's on Lemmy? If not, if you can contact him, tell him to pass by!

peregus ,

😆

peregus OP ,

Hi Antsu, thanks for your precious feedback!
