Debian disable IPv6

Since Debian 6 (squeeze) this is the working method to disable permanent IPv6 implementation. This method is also reboot safe.

cat /etc/sysctl.d/disable-ipv6.conf
net.ipv6.conf.all.disable_ipv6=1

cat /etc/sysctl.d/disable-ipv6.conf net.ipv6.conf.all.disable_ipv6=1

If you have no possibility to restart your system yet, this change can be made immediately work by executing:

sysctl -p /etc/sysctl.d/disable-ipv6.conf

sysctl -p /etc/sysctl.d/disable-ipv6.conf

Anothe method – perfect for firewall scripts:

echo 1 > /proc/sys/net/ipv6/conf/all/disable_ipv6

echo 1 > /proc/sys/net/ipv6/conf/all/disable_ipv6

Inetd listens for connections on certain sockets. When a connection is found on one of its sockets, it decides what service the socket corresponds to, and invokes a program to service the request. The server program is invoked with the service socket as its standard input, output and error descriptors.

Essentially, inetd allows running one daemon to invoke several others [Read more…]

Bonding

Bonding

This will be about how to “bond” two Ethernet connections together to create an virtual auto failover interface.

If you have from the same ISP (internet service provider) two redundant (different) uplinks, you could create a failover solution.

Debian way installation – was tested on debian squeeze.

First we install the ifenslave-2.6 package, necessary to enable bonding on the system:

1
apt-get install ifenslave-2.6

apt-get install ifenslave-2.6

Next we configure some network stuff [Read more…]
