VBox internal linux:centos5.5 with external pings (mutual), and domain access

1 Mutual Ping Pass: Can not use Nat,nat can only one-way pass, virtual machine can not ping the host, select Bridge:

2 Then set the IP: It is better to set the static IP so next time do not have to change, here we only demonstrate the use of eth0 network card, = "Vi/etc/sysconfig/eth0,

The subnet mask here, the gateway is consistent with my host network card,

DNS1 here also to be consistent (do not set or RESOV.CNF not set is not able to access the domain name), IP can

3 Disable SELinux (for Domain name resolution)

[Email protected] tomener]# Vim/etc/selinux/config


# This file controls the state of the SELinux on the system.
# selinux= can take one of these three values:
# Enforcing-selinux security policy is enforced.
