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
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 |
Next we configure some network stuff [Read more…]
