File: modules/NetHwDetection.ycp Package: Network configuration Summary: Network detection Authors: Michal Svec

Detects network settings, using dhcp or sniffing network traffic

Detection process:

Initial stage:

• hardware detection
• load kernel modules (if not already active *1)
• set up interface (if not already set up *2)
• run detection

Final stage:

• read detection data
• shut down interfaces (if set up before, see *2)
• remove kernel modules (if loaded before, see *1)

Used software:

• dhcpcd(8)
• netprobe(8) (currently not, originally by Caldera, license unclear)

Usage:

• Detection::Start() somewhere at the start of installation

Later at the module:

• if(Detection::running) Detection::Stop();
• string gw = Detection::result["GATEWAY"]:"";

Detection result (in dhcpcd-interface.info format)

True, if detection is running

Set up the first eth interface, if not already running WATCH OUT, this is the place where modules are loaded

Return value:

true if success

Start the detection

Return value:

true on success

Stop the detection

Return value:

true on success

Duplicate IP detection

ip	tested IP address
