Thanks for help from this gropup I can force the use of IPv4 by
running: sysctl -w net.ipv6.conf.all.disable_ipv6=1.
If you would like to prevent the kernel from loading IPv6 simply add the
following: ipv6.disable=1 to the kernel boot parameters. If you use lilo
then in the /etc/lilo.conf should be line beginning with append:
image=/boot/vmlinuz
root=/dev/md0
label=DebianSid
initrd=/boot/initrd.img
append="net.ifnames=0 biosdevname=0 ipv6.disable=1"
In case of grub.conf search for the line beginning with "linux":
# For booting GNU/Linux
menuentry "Stretch - remote" --id deb {
set root=(hd0,msdos2)
linux /boot/vmlinuz root=/dev/sda2 net.ifnames=0 biosdevname=0
ipv6.disable=1
initrd /boot/initrd.img
}
After reboot you should see ipv6.disable=1 in /proc/cmdline
