Member Function Documentation

int NetworkManager::bringInterfaceDown

(

QString

ifname

)

The method brings an interface down.

Parameters:

ifname

the name of the interface

Returns:

0 -> success -1 -> error

int NetworkManager::bringInterfaceUP

(

QString

ifname

)

The method brings an interface up.

Parameters:

ifname

the name of the interface

Returns:

0 -> success -1 -> error

Here is the caller graph for this function:

int NetworkManager::ip4_configureInterface	(	QString	ifname,
		QString	ipAddress,
		QString	broadcast,
		QString	netmask,
		int	af
	)

Here is the caller graph for this function:

int NetworkManager::ip4_setManualConfiguration	(	QString	ifname,
		QString	ipAddress,
		QString	netmask,
		QString	broadcast,
		QString	gateway,
		int	metric,
		int	af,
		QString	pathToResolvConf,
		QList< QString >	nameServer
	)

This method is used when the manual configuration is needed.

This method is used when the manual configuration is needed. First we bring up the interface. Than we configure the interface with our manual entered configuration dates. After that we replace the old default route with the new and write a resolv.conf.

Parameters:

ifname	name of the interface which we are about to configure.
ipAddress	the new IP-Address.
netmask	the netmask of the IP-Address.
broadcast	the broadcast address.
gateway	the gateway address.
metric	do not exactly know why we need this. in most cases this should be 0.
af	the address type. Either AF_INET for IPv4 or AF_INET6 for IPv6.
pathToResolvConf	the path to the resolf.conf file. in most cases "/etc/".
nameServer	the name server addresses.

Here is the call graph for this function:

Here is the caller graph for this function:

int NetworkManager::ip6_addAddress	(	struct ip6_addr *	ip6Addr,
		const char *	iface
	)

int NetworkManager::ip6_addRoute	(	const char *	iface,
		const struct in6_addr *	ip6_dest,
		int	ip6_prefix,
		const struct in6_addr *	ip6_gateway,
		int	metric,
		int	mss
	)

int NetworkManager::replaceDefaultRoute	(	QString	ifname,
		QString	gateway,
		int	mss,
		int	af
	)

This method adds /replaces the default route. This method adds /replaces the default route. To keep it modular, it is possible to specify an ip address family.

Parameters:

ifName	the interface name
gateway	the gateway address (e.g: 192.168.0.254)
mss	the mss.
af	specify the family type of the ip address. possible values are: AF_INET for an IPv4 address AF_INET6 for an IPv6 address

Returns:

return -1 if an error happened. return 0 if everything was ok.

Here is the caller graph for this function:

int NetworkManager::writeResolvConf	(	QString	path,
		QString	ifname,
		QList< QString >	nameServer
	)

This method writes a resolv.conf file.

Parameters:

path	path to the resolv.conf file. (in most cases: /etc/)
ifname	name of the interface
addresses	of the nameserver

Returns:

return 0 if success else -1
