Question: What is Linux misinformation? in c/[email protected]
[–] [email protected] 2 points 6 days ago* (last edited 6 days ago)

For me, it's hardware support, i.e my laptops fingerprint sensor just isn't supported, for the speakers to work I had to find a script that remapped the speakers, multiple desktops (especially with different resolutions) are a pain.

But the killer at the moment is a good solution to manage and post process my raw photos. Went from Lightroom to On1 Photo RAW...unfortunately DarkTable is still not there yet. Also still missing the affinity suite on Linux :-(

Also, sadly these tools also don't run well in a VM

That would be an argument....IF it would be consistently 16 between each unit

Jup, Im having an NTP issue on my win10 machine If you search for it you find the same 5 "solutions" from dozens of content farms.

What tool do you use to display your self-hosting infrastructure in c/[email protected]
[–] [email protected] 3 points 2 months ago

I'm coding them down as plantuml network code and render them using a selfhosted plantuml Server.

In the end my whole admin guide resides in a obsidian notebook as markdown There is even a plugin that renders plantuml code within obsidian

The nice thing: everything is just code and can be moved to any other tool (had my documentation in a local gitlab repo, but I swapped gitlab out for gitea)

Yep, I went in this direction...until I gave in during a bare metal install of something...

Docker is not hassle free but usually most setup guides for apps are much much easier with docker

I changed the native vlan to '83' and allowed all others

The isoöation is done with firewall rules blocking access from the IoT net to default, with some exceptions (dns, media nas (currently), etc.)

So if I understand this right you will need to change the network on the port attached to the synology in your UniFi configuration or set the vlan tag in the synology OS, I would do the former.

doesn't the switch terminate any VLAN tagging at the port? so if I add the VLAN to the DSM configuration it doesn't receive any tagged packages and refuses them?

It sounds like you just added a second network/vlan to the existing interface which means you actually created a trunk and are getting the old network untagged and the new network with vlan tags which the synology is dropping.

with all the other devices in the IoT subnet it works with setting the VLAN on the port of the switch. If I check back on the unifi site, I found this:

'Applying a VLAN to a Switch Port
Native VLAN

The Native VLAN is the VLAN assigned to "untagged" traffic passing through a switch port. Devices physically connected to a switch port will be placed on this Native VLAN.
Tagged Networks and Trunk Ports

Ports can be configured to allow traffic from other networks. Allowing specific networks/VLANs is referred to as “tagging” them on the switch port. You can see all ports’ VLAN tags in the VLAN Viewer, found in the Ports tab.

Ports that have been tagged to allow traffic from multiple VLANs are referred to as “trunk” ports. By default, all ports on UniFi Switches are trunked to allow all VLANs. '

if I understand that in combination with your comment correctly: I set the native VLAN to 83 so everything tagged with 83 is correctly forwarded to the NAS and accepted there, stuff tagged with 1 are non native, the tag stays on and the NAS doesn't accept it?

But that would make the Synology NAS quite hard to use in any corporate setting with multiple VLANs which need to interconnect and why does it work the other way around? while being in the default net 1 it does accept stuff from VLAN 83

Synology OS also doesn’t really support trunked ports through the UI (even though it does support a port that only uses a vlan tag) so it’s much easier to just leave them untagged.

which would mean, I can't put it in the IoT net?

Synology not working in different subnet - please help (discuss.tchncs.de)
 

Hi everyone

I'm fighting with a network issue, where my synology nas doesn't accept any connection from outside it's subnet.

So, here's my setup:

  • Unifi Infrastructure with three separated subnets:

    • default: xxx.xxx.2.0/24 - no vlan - pool with all "safe" devices (notebooks, mobiles, servers etc.)
    • IoT: xxx.xxx.83.0/24 - vlan 83 - here are all the IoT devices, including nvidia shield, multiple chromecast music devices etc.)
    • guest: xxx.xxx.20.0/20 - vlan 20 - quarantined guest wlan
    • dns server are locally hosted at xxx.xxx.2.42 and 43

  • my I got a new NAS and i designated my old DS214play (running DSM 7.1.1-42962 Update 6) as a Mediaserver that gets to live in the IoT net:

    • changed the ip from xxx.xxx.2.50 to xxx.xxx.83.50
    • updated the gateway and subnet
    • added the vlan tag 83 on the network port
    • updated the firewall to allow all necessary ports from and to the default network (so I can stream plex to my notebooks etc.)

  • The Firewall on the NAS is not activated

Issue:

  • My NAS doesn't accept any outside connections after moving it to the IoT subnet, neither from my default network nor the internet.

What I tried:

  • allowed full access between LAN and IoT subnet for the NAS.
  • tried it with another port -> same issue
  • connected another device to this port (and setup the same firewall rules) -> this one works fine.
  • checked the unifi firewall logs --> requests get sent from the nas and answers from the other device
  • checked logs of other devices (DNS, NetCat etc.) --> they receive the requests outside of the subnet, and return their anser but the NAS seems to block/ignore any incoming packages.

What I didn't try:

  • setting the VLAN id under "Network Interface" > "LAN" > "Enable VLAN(802.1Q)" since, as far as I understand, the Unifi VLAN implementation terminates the VLAN tag at the port of the switch (and all other devices work without specifying it locally)
  • fully reset the NAS

I'm completely stuck how to solve the issue, so I have moved the NAS back to the default net, but some use cases are not working properly that way, so I'd really like to move it to the IoT subnet. Does anybody have (has?) any hints or knows of some obscure settings which need to be updated? I'd be really grateful for any pointers.

Issue with windows 10 time sync - Need help (discuss.tchncs.de)
 

Hi everyone, I hope I'm right here with this question and you can help me with an issue that follows me since a few months now where I'm struggling with the NTP synchronization on my windows 10 PC...

The issue only happens with this one device, all other devices can sync their time with whichever ntp server I chose.

I'm even able to contact the ntp server via netcat on this exact device (Opensuse running via WSL), so it's definitely not a network issue:

nc -u -vvv time.windows.com 123
Connection to time.windows.com 123 port [udp/ntp] succeeded!

I tried all the standard solutions:

  1. stop and restart the Windows Time service
  2. change ntp pool
  3. unregister and re-register via cmd:
net stop w32time
w32tm /unregister
w32tm /register
net start w32time
w32tm /resync

Sending resync command to local computer
The computer did not resync because no time data was available.
  1. the peers seem to be listed correctly if I query them:
w32tm /query /peers
#Peers: 4

  1. Group Policies are also as the should be: Link to learn.microsoft
  2. Defining the servers in the registry Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\DateTime\Servers
  3. Also, w32tm /stripchart can contact the server:
w32tm /stripchart /computer:ntp.metas.ch /samples:5 /dataonly
Tracking ntp.metas.ch [195.176.26.215:123].

In the meantime I even completely wiped the disk and reinstalled windows 10 from scratch, but no luck.

I really don't know what else to do and where to look, since the error messages from windows are also not really helpful.
