Hello, everyone! I am a newer. I want to use the user mode linux to make a insight into the tcp/ip stack.my operating system is Ubuntu 9.10 - Karmic Koala.I construct the user mode linux following the commands in the http://user-mode-linux.sourceforge.net/ website.I download the linux-2.6.32 kernel source.
make defconfig ARCH=um make ARCH=um I download the Ubuntu-KarmicKoala-i386-root_fs. ./linux ubda=Ubuntu-KarmicKoala-i386-root_fs mem=128M the boot is right.Then I login in as the root user and left password is none. But I cann't log in. Then I download the Debian-5.0-x86-root_fs. ./linux ubda=Debian-5.0-x86-root_fs mem=128M the boot is right. And I login in as the root and the password is none. my login is right. Then I config the network. My computer is in the local net.It's address is 192.168.237.112. in the host: modprobe tun modprobe iptable_nat iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE echo 1 > /proc/sys/net/ipv4/ip_forward linux ubda=Debian-5.0-x86-root_fs eth0=tuntap,,,192.168.237.115 mem=128M in the UML: ifconfig eth0 192.168.237.116 up helper_wait : waitpid process 4699 failed, errno = 10 * modprobe tun * ifconfig tap0 192.168.237.115 netmask 255.255.255.255 up * bash -c echo 1 > /proc/sys/net/ipv4/ip_forward helper_wait : waitpid process 4704 failed, errno = 10 * route add -host 192.168.237.116 dev tap0 * bash -c echo 1 > /proc/sys/net/ipv4/conf/tap0/proxy_arp * arp -Ds 192.168.237.116 eth0 pub IRQ 5/eth0: IRQF_DISABLED is not guaranteed on shared IRQs route add default gw 192.168.237.115 when i ping the 192.168.237.116,the host is unreable. when i ping the 127.0.0.1, the host is alow unreable.
