If the output includes lines like this, then IPv6 has been disabled through sysctl settings: _ipv6 = 1 You should also check the sysctl settings: grep "disable_ipv6" /etc/nf /etc/sysctl.d/*.conf (In theory, unloading and re-loading the ipv6 after commenting out the disable option should suffice, but because of dependencies between modules, it might be hard to actually do without rebooting.) Methods applicable for both modular and compiled-in IPv6 To re-enable IPv6 in this case, find that line, comment it out, and run update-initramfs -u as root to make sure IPv6 does not get disabled at early boot, as this disabling strategy may require a reboot to re-enable.
Then IPv6 is disabled by kernel module configuration, and you should find that line in one of the files in /etc/modprobe.d. If the response includes a line: options ipv6 disable=1 Please run modprobe -c |grep "options ipv6" as root. In this case, one way to disable IPv6 would be to add boot option ipv6.disable=1 to the kernel command line (in /etc/default/grub if using GRUB bootloader, or in /boot/cmdline.txt on a Raspberry Pi bootloader) but you said you've already checked for that. Then IPv6 support is compiled in to the main kernel. If there is instead a line: CONFIG_IPV6=y Then the IPv6 support is compiled as a kernel module. If the response includes a line: CONFIG_IPV6=m
#Ixgbe.conf modprobe debian buster install
In this case, you would have to install a new kernel package (or build and install a custom kernel) to enable IPv6. Then your current kernel had its IPv6 support disabled at compilation time. If the response is nothing at all, or includes a line: # CONFIG_IPV6 is not set Or if the /boot/config- file does not exist, run this command instead: modprobe configs zcat /proc/config.gz | grep CONFIG_IPV6= Please run grep CONFIG_IPV6= /boot/config-$(uname -r)Īnd see what it says. If you are using a custom kernel, IPv6 may be disabled at kernel compilation time, in which case you'll need to recompile the kernel (or switch to another kernel) to get it enabled. so you need to write tg3(or your driver) in the place of driver-name.There are many ways to disable IPv6 in Linux, so you'll have to check for them all.įirst, your kernel version does not quite look like Debian 10 standard AMD64 kernel.

#Ixgbe.conf modprobe debian buster driver
For example, If you wanted to disable the NIC card driver, you can find the name of kernel driver for your LAN card by using the command lspci -v command in a terminal.Ħ:00.0 Ethernet controller: Broadcom Corporation NetLink BCM5906M Fast Ethernet PCI Express (rev 02)įlags: bus master, fast devsel, latency 0, IRQ 46 Note: here driver-name is the name of your desired blacklist driver. Reboot your box and use lsmod command to show the status of modules in the Linux Kernel Just open your /etc/modprobe.d/blacklist file and add drivername using following syntax: blacklist driver-nameĮDIT: In later versions since 12.10 (12.04?) the file is /etc/modprobe.d/nf The only way to disable such modules is via a kernel parameter (if available) or by recompiling the kernel. Note: blacklisting will not work for modules which are built into the kernel image (i.e.
