Sharing is caring. For this situations there are following command line methods to provide some data to be downloaded from everywhere.
On the most common linux systems is python preinstalled or is a part of the core system,
so the next two python-examples should work like a charm.

The BeagleBone is the low-cost, high-expansion hardware-hacker focused BeagleBoard. It is a bare-bones BeagleBoard that acts as a USB or Ethernet connected expansion.
BeagleBone brings full-featured Linux to places it has never gone before.

It’s sometimes useful to prevent some kernel modules from loading. This howto will show you how to do this. This is really easy to do, so if you want you can just skip to the end to see some examples.
Load manualy kernel modules:
1 | modprobe ip_conntrack_ftp |
List all loaded modules:
1 | lsmod |
This option remove loaded module:
1 | modprobe -r pcspkr |
Creating a blacklist:
1 2 | cat /etc/modprobe.d/blacklist-custom blacklist pcspkr |
I show you, how to add a secondary IPv6 Address to your existing one.
You need only to edit “vim /etc/network/interfaces” file and add the IPv6 networking configuration.
1 2 3 4 5 6 7 8 9 10 11 12 13 | # The loopback network interface auto lo iface lo inet loopback # The primary network interface auto eth0 iface eth0 inet static address 10.1.100.4 gateway 10.1.100.1 netmask 255.255.255.0 pre-up modprobe ipv6 post-up ip addr add 2001:470:1f0b:1514::4/64 dev eth0 post-up ip route add default via 2001:470:1f0b:1514::1 dev eth0 |
Another way to do the same:
1 2 3 4 5 6 | pre-up modprobe ipv6 iface eth0 inet6 static address 2001:470:1f0b:1514::4 netmask 64 gateway 2001:470:1f0b:1514::1 |
Also you can put the ipv6 module in to “/etc/modules” instead of “pre-up modprobe ipv6”
Test it:
1 | ping6 ipv6.google.com |
