I formatted and reinstalled Linux this morning, so as to remove the possibility I have accidently changed a file. Here is the result of changing my route table: route -F add default gw 169.254.214.162 [169.254.214.162 is the IPv4 address of my windows machine.] glenn(a)glenn-desktop:/sbin$ route Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 10.42.43.0 * 255.255.255.0 U 1 0 0 eth0 link-local * 255.255.0.0 U 1000 0 0 eth0 glenn(a)glenn-desktop:/sbin$ route -F add default gw 169.254.214.162 SIOCADDRT: Operation not permitted glenn(a)glenn-desktop:/sbin$ sudo route -F add default gw 169.254.214.162 glenn(a)glenn-desktop:/sbin$ route Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 10.42.43.0 * 255.255.255.0 U 1 0 0 eth0 link-local * 255.255.0.0 U 1000 0 0 eth0 default 169.254.214. 162 0.0.0.0 UG 0 0 0 eth0 glenn(a)glenn-desktop:/sbin$ Does that look in order?
