How to enable IPv6 on command line ?

[NicoxOne]

Hello,

I have a new host in a IPv6 environnement.
However, it seems like that by default, IPv6 is not enabled.

Code:

nico@wana:~$ sudo netstat -l
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address          Foreign Address        State
tcp        0      0 0.0.0.0:8096            0.0.0.0:*              LISTEN
tcp        0      0 _localdnsproxy:domain  0.0.0.0:*              LISTEN
tcp        0      0 _localdnsstub:domain    0.0.0.0:*              LISTEN
tcp6      0      0 [::]:ssh                [::]:*                  LISTEN
udp        0      0 0.0.0.0:7359            0.0.0.0:*
udp        0      0 _localdnsproxy:domain  0.0.0.0:*
udp        0      0 _localdnsstub:domain    0.0.0.0:*
raw6      0      0 [::]:ipv6-icmp          [::]:*               

We can see the port openned on tcp but not on tcp6.

Is there a way to enable it by command line on the linux host ?
 Thank you

IPv6 is enabled by default in pretty much every modern Linux distro. But your ISP and your router needs to support it. And a lot routers don't enable IPv6 by default so you'd need enable it, assuming your ISP supports IPv6.

No the IPv6 is working fine on the host. It is that the jellyfin application only enable IPv4 by default (as I believe).
Since I don't have any IPv4, I cannot go on the web ui of jellfin to enable IPv6.
I think that should be a way to enable this setting without the web ui ?

I found out about a network.xml file, but since it is a fresh install, I feel like it is missing.

Check /etc/jellyfin for the network.xml file. If its not there, here is my file you can use as a template.

Code:

<?xml version="1.0" encoding="utf-8"?>
<NetworkConfiguration xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <BaseUrl />
  <EnableHttps>false</EnableHttps>
  <RequireHttps>false</RequireHttps>
  <InternalHttpPort>8096</InternalHttpPort>
  <InternalHttpsPort>8920</InternalHttpsPort>
  <PublicHttpPort>8096</PublicHttpPort>
  <PublicHttpsPort>8920</PublicHttpsPort>
  <AutoDiscovery>true</AutoDiscovery>
  <EnableUPnP>false</EnableUPnP>
  <EnableIPv4>true</EnableIPv4>
  <EnableIPv6>true</EnableIPv6>
  <EnableRemoteAccess>true</EnableRemoteAccess>
  <LocalNetworkSubnets />
  <LocalNetworkAddresses />
  <KnownProxies />
  <IgnoreVirtualInterfaces>true</IgnoreVirtualInterfaces>
  <VirtualInterfaceNames>
    <string>veth</string>
  </VirtualInterfaceNames>
  <EnablePublishedServerUriByRequest>false</EnablePublishedServerUriByRequest>
  <PublishedServerUriBySubnet />
  <RemoteIPFilter />
  <IsRemoteIPFilterBlacklist>false</IsRemoteIPFilterBlacklist>
</NetworkConfiguration>

That's perfect, thank you.
I could access the web-ui in IPv6 only.

It might be a good idea to enable IPv6 by default to avoid this hurdle
