If you're going to put the two ends of the tap device on different networks, you'd better learn how to set up routing appropriately. Jeff |

I had mistakenly assumed that tun/tap simply delivered all packets to the other side. After I changed it to the same network, it worked On the host side, I did see the net helper set up a route to the uml interface . So why does it not set up the other way round? -Girish __________________________________________________ Do You Yahoo!? LAUNCH - Your Yahoo! Music Experience http://launch.yahoo.com |

Because it can't because it's on the host and has no access to UML and because a route is set up automatically anyway. Jeff |

My host is Gentoo with a 2.4.19 kernel.I am using UML 2.4.18-24 I used the switch eth0=tuntap,,,192.168.x.x while booting UML. I see that IP is assigned to tap0 interface on the host. Inside UML I do a ifconfig eth0 10.0.0.3 up When I try to ping a host interface from UML, I get a sendto: Network is unreachable. I can't ping UML eth0 from the host either. Am I missing smoething? -Girish __________________________________________________ Do You Yahoo!? LAUNCH - Your Yahoo! Music Experience http://launch.yahoo.com |
