* pingu_iface: del renewed gateways via broken ISPsNatanael Copa2012-03-231-0/+13
| | | | | | | | | | If we get a new default gateway for an interface that is marked "down", remove the default gw again from main table and let pingu detect that it went up This solves the case when dhcp will renew a lease, recreates the default gw and ISP is broke a bit futher down the road.
* pingu_adm: support route dumpsNatanael Copa2012-03-141-0/+11
|
* pingu_adm: new admin command for dumping active pingsNatanael Copa2012-03-141-3/+14
|
* pingu_ping: always stop ev timer when cleaning up ping listNatanael Copa2012-03-141-2/+2
|
* pingu: cleanup various structures on shutdownNatanael Copa2012-03-061-1/+13
|
* pingu_netlink: keep track of the route via interfaceNatanael Copa2011-12-081-1/+1
| | | | | This is so we later can copy more routes to alternate rotue table if needed.
* pingu_adm: implement host-status and gateway-statusNatanael Copa2011-10-121-0/+15
|
* pingu_iface: support binding multiple ping hosts to same ifaceNatanael Copa2011-10-071-1/+35
| | | | | | | Add config option for executing actions when interface gateway goes up/down. Add config option for required hosts up per interface (defaults to 1)
* pingu: rename pingu_gateway to pingu_routeNatanael Copa2011-10-071-10/+10
|
* pingu_iface: only load-balance if 2 or more interfaces are configured for itNatanael Copa2011-09-211-14/+16
| | | | | We should not try load-balance at all if there are only 1 or less interfaces configured with "load-balance"
* pingu_netlink: delete multipath route if there are no pathsNatanael Copa2011-09-091-2/+2
| | | | | | The normal action is to replace but if all ISPs goes down we need to explicit delete the multipath route. Otherwise we will have the last default gw hanging around.
* pingu_iface: only update default route in main route tableNatanael Copa2011-09-091-1/+2
| | | | | This is related the d3c9eca81e94978284e619aca58cee93977f30a7 fix where we save all the routes in list, not only default gateways.
* pingu_iface: only update multpath route when route is a default gwNatanael Copa2011-09-081-3/+4
| | | | | We now save all routes in list but we don't need update multipath routes unless the changed route is a default gateway.
* pingu_iface: cleanup load-balance route on exitNatanael Copa2011-09-071-2/+19
|
* pingu_{iface,netlink}: only remove route rules that we actually createdNatanael Copa2011-09-071-1/+2
|
* pingu_iface: bind to interface tooNatanael Copa2011-09-061-0/+5
| | | | This is so we only see the pings for that interface
* pingu: cleanup on exitNatanael Copa2011-09-061-0/+9
| | | | We remove the ip rule, close the ping sockets and netlink sockets.
* pingu: only create/lose binding when we get/lose addressNatanael Copa2011-09-061-1/+4
| | | | | We don't need to rebind every burst. We only bind when we get an address and we only lose the binding when the address is lost.
* pingu_iface: bind to address instead of oifNatanael Copa2011-09-061-2/+2
| | | | | Seems like ip rule does not work with source address unless we bind to address
* pingu_iface: fix for previous commitNatanael Copa2011-08-161-1/+1
|
* pingu: implement load balancing with nexthopsNatanael Copa2011-08-151-0/+2
| | | | We do loadbalancing by creating a new default gw with nexthops
* pingu_gateway: cleanup. split out gateway funcsNatanael Copa2011-08-051-105/+10
| | | | | To make code cleaner we move all gateway functions to separate file and rename a few functions.
* pingu: implement new config formatNatanael Copa2011-08-051-18/+32
| | | | | | | | | | | | | | | | | | | | | New format allows users to define interfaces and ping hosts separately. This means we can run pingu in routing-only mode to set up and manage route tables for multi-isp. We allow the user config a preferred alternate route table for each interface. If not configured, pingu will pick one. Example interface definition looks like: interface eth0 { route-table 10 } Example host definition looks like: host 192.168.0.1 { bind-interface eth0 }
* pingu_iface: init the sockets when init instead of when createNatanael Copa2011-08-021-6/+8
|
* pingu: use source address for ip rule and copy scope link routeNatanael Copa2011-08-021-4/+8
|
* pingu: remove default gw from main route table when isp goes downNatanael Copa2011-07-291-0/+9
|
* pingu: delete gateway from our listNatanael Copa2011-07-281-0/+49
|
* pingu: clean up for ipv6 support in futureNatanael Copa2011-07-281-16/+27
| | | | | | | make the pingu_gateway struct also hold a destination so the struct can be reused. use sockaddr_any as much as possible.
* pingu: add gw to list and minor cleanupNatanael Copa2011-07-281-13/+29
| | | | | | | | - add default gateways to our gw list - use sockaddr_init to init our gw - implement sockaddr_to_string TODO: delete default gateways from list
* pingu: use sockaddr_anyNatanael Copa2011-07-281-8/+49
| | | | add common sockaddr utility functions
* Use sockaddr_any for storing address and gatewayNatanael Copa2011-07-281-1/+1
|
* pingu: add initial code to modify routing tablesNatanael Copa2011-07-211-2/+7
| | | | | For now we just create the alternate routing tables from table 10 and +1 for each new interface. First interface is 10, second is 11 etc.
* pingu_netlink: pick up primary address for interfacesNatanael Copa2011-07-151-2/+31
|
* pingu_netlink: monitor link status of interfaces via netlinkNatanael Copa2011-07-131-2/+1
|
* pingu_iface: implement pingu_iface_usable()Natanael Copa2011-07-131-0/+7
| | | | To test if we can use socket.
* pingu: try bind socket to interface every burstNatanael Copa2011-07-131-11/+15
| | | | | | It might be an interface that disappeared and came back, e.g ppp0. We also don't even try unless we have a successful binding.
* pingu_iface: fix bugNatanael Copa2011-07-131-1/+1

* iface: add initial implementationNatanael Copa2011-07-071-0/+104
