import debinterface # Get a collection of objects representing the network adapters. adapters = debinterface.Interfaces().adapters # You get a list you can iterare over. # Each adapter has an 'export()' method that returns a dictionary of its options. # You can print the name of each adapter as follows: for adapter in adapters: item = adapter.export() print(item['name']) # Write your new interfaces file as follows: # Any changes made with setter methods will be reflected with the new write. interfaces = debinterface.Interfaces() interfaces.writeInterfaces() # A backup of your old interfaces file will be generated when writing over the previous interfaces file # By defaults these paths are used : # INTERFACES_PATH='/etc/network/interfaces' # BACKUP_PATH='/etc/network/interfaces.old' # Paths can be customized when instanciating the Interfaces class: interfaces = debinterface.Interfaces(interfaces_path='/home/interfaces', backup_path='/another/custom/path') # By defaults, interfaces file is read when instanciating the Interfaces class, to do it lazyly: interfaces = debinterface.Interfaces(update_adapters=False) interfaces.updateAdapters()
