Hi,
I have a rather strange problem in regard to routing and tcp/ip connections.
My setup: - default route to eth0, metric 2 - ppp dialin to static ip (ppp0), is another default route, metric 0
I open a telnet connection over the ppp0 interface.
I then down and remove the ppp0 interface (ifconfig -a ppp0 shows 'no such device'), the default route over ppp0 is gone.
Symptom: The telnet connection hangs.
No packets are transmitted over the still alive eth0 defaultroute. tcpdump -i eth0 shows 0 packets, "netstata -a" shows an increasing SendQ on the connection.
If I dialin again, the still hanging packets get transmitted to the target.
I am not sure, but should this be?
Shouldn't packets get routed over eth0 in the case an interface vanishes?
