how to fully enable IPv6?
« on: November 23, 2019, 04:49:40 PM »
I'm finding that having ipv6-4.19.10-tinycore64.tcz in onboot.lst does not seem to fully enable IPv6.

This is what I see in my Pure64 10.1 laptop after connecting to an IPv6-enabled wireless router (note the absence of inet6 line):

Code: [Select]
tcl$ ifconfig wlan0
wlan0     Link encap:Ethernet  HWaddr 00:26:B6:F6:04:E4 
          inet addr:192.168.43.221  Bcast:192.168.43.255  Mask:255.255.255.0
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:67 errors:0 dropped:0 overruns:0 frame:0
          TX packets:64 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:13766 (13.4 KiB)  TX bytes:10891 (10.6 KiB)

While in other distros I get this:
Code: [Select]
devuan$ ifconfig wlan0
wlan0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 192.168.43.211  netmask 255.255.255.0  broadcast 192.168.43.255
        inet6 fe80::9919:79dd:137f:2dcf  prefixlen 64  scopeid 0x20<link>
        ether 00:26:b6:bf:39:5d  txqueuelen 1000  (Ethernet)
        RX packets 1048  bytes 1031550 (1007.3 KiB)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 1015  bytes 134380 (131.2 KiB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

In TCL I'm connecting with wpa_supplicant plus dhclient with these commands:

Code: [Select]
wpa_passphrase "$ssid" "$password" > $auth_file
wpa_supplicant -i $iface -c $auth_file &
dhclient -v -cf /etc/dhcp/dhclient.conf $iface
Can you please help me fully fully enable IPv6?

Sometimes running ip -6 addr and then running ifconfig wlan0 again makes the inet6 line magically appear (but sometimes it doesn't help). Here is a successful run:

Code: [Select]
tcl$ ifconfig wlan0
wlan0     Link encap:Ethernet  HWaddr 00:26:B6:F6:04:E4 
          inet addr:192.168.43.221  Bcast:192.168.43.255  Mask:255.255.255.0

          collisions:0 txqueuelen:1000
          RX bytes:13766 (13.4 KiB)  TX bytes:10891 (10.6 KiB)

Strange. How to fully enable IPv6 right off the bat, without any shenanigans?

Hi GNUser
My wired connection has IPV6 without any "shenanigans".
The script I call from bootlocal to set up my Ethernet card:
Code: [Select]
tc@E310:~$ cat /opt/eth0.sh
#!/bin/sh
pkill udhcpc
ifconfig eth0 192.168.1.35 netmask 255.255.255.0 broadcast 192.168.1.255 up
route add default gw 192.168.1.1
echo nameserver 192.168.1.1 > /etc/resolv.conf
echo nameserver 68.237.161.12 >> /etc/resolv.conf

Ah, just realized that dhclient defaults to IPv4. Even specifying IPv6, I'm not doing much better:

Thank you, Rich. Interesting that you get an IPv6 address without explicitly asking for one.

In output of lsmod I also see "ipv6":

Hi GNUser
If you execute:
Code: [Select]
sudo sysctl -a | less -Iyou'll find there are lots of ipv6 settings. I noticed there are also dummy0, lo, eth0, etc. settings. I wouldn't be surprised if on your
hardware there are also a bunch of wlan0 settings.

Thanks again, Rich.

I've discovered something interesting: It is only a minute or more after wifi connects (with IPv4) that the IPv6 settings appear.

Code: [Select]
$ sysctl -a | grep wlan0
net.ipv4.conf.wlan0.accept_local = 0
net.ipv4.conf.wlan0.accept_redirects = 1

At this point (a minute or more after boot), sudo dhclient -6 -v -cf /etc/dhcp/dhclient.conf wlan0 works just fine (as would be expected now that the kernel actually supports ipv6).

Very strange. Since ipv6-4.19.10-tinycore64.tcz is in my onboot.lst, shouldn't the ipv6 settings be available as soon as I get to my desktop after booting?

Hi GNUser
... Very strange. Since ipv6-4.19.10-tinycore64.tcz is in my onboot.lst, shouldn't the ipv6 settings be available as soon as I get to my desktop after booting? ...
Two thoughts:
1. Try moving  ipv6-4.19.10-tinycore64.tcz  earlier in your  onboot.lst.
2. I'm also using the  nodhcp  bootcode.  /etc/init.d/dhcp.sh  was separated from  tc-config  because it may take a while to finish.

Just to exclude me being the problem, here is what I'm seeing before I run ANY network-related commands after booting:

Code: [Select]
bruno@box:~$ tce-status -i | grep ip
bzip2-lib
iproute2
iptables
ipv6-4.19.10-tinycore64
p7zip
bruno@box:~$ sysctl -a | grep ipv6
bruno@box:~$

As you can see, ipv6-4.19.10-tinycore64 is loaded but it seems to have no effect.

No luck, Rich. I put ipv6-4.19.10-tinycore64.tcz at the very top of onboot.lst and used the nodhcp boot code.

This is still what I'm seeing when I get to my desktop:

Code: [Select]
bruno@box:~$ tce-status -i | grep ipv6
ipv6-4.19.10-tinycore64
bruno@box:~$ sysctl -a | grep ipv6
bruno@box:~$

Is there a command that I can manually run after getting to my desktop that would force the kernel to "notice" the contents of ipv6-4.19.10-tinycore64.tcz?

Is it possible something in  iproute2  or  iptables  has been started and is delaying ipv6 ?

Does  lsmod  show  ipv6  is loaded at that point in time?

Strong thinking, Rich. No, according to lsmod, ipv6 is not loaded at that point.

I changed my wifi-connect script to this, and now it works as expected:

Code: [Select]
modprobe ipv6
wpa_passphrase "$ssid" "$password" > $auth_file
wpa_supplicant -i $iface -c $auth_file &
dhclient -v -cf /etc/dhcp/dhclient.conf $iface

Turns out the single dhclient command above gets an IPv4 address and an IPv6 address as well, no there's no need to run dhclient a second time with the -6 flag.

Thank you, Rich. You are an amazing resource. This is solved.

curaga and juanito:

/usr/local/tce.installed/ipv6-4.19.10-tinycore64 in ipv6-4.19.10-tinycore64.tcz should probably contain this:

Code: [Select]
#!/bin/sh
modprobe ipv6
