for internet, you have to configure the /etc/resolv.conf and nsswitch.conf for the DNS.
check the /etc/hosts permission. Is the system in run level 3? or is there any cdrom ur using at the moment?
how are you trying to modify your files? what is your userid? what system do you use? how do you login?
please be more exact on what you have done and how!
i have been logging as root .I just wanted to edit my /etc/hosts through vi but it is opening in read only mode and the permissions for the file are 777..and also iam not able to get into some directories like usr/adm and saying the message permission denied..but i logged in as root user..

/etc/hosts is a symbolic link to /etc/inet/hosts and the permissions on /etc/inet/hosts is read-only. Root can override that. When you
vi /etc/hosts
use the command:
:wq!
to force the system to write the file. Or change the permissions of /etc/inet/hosts.
indeed this is... this also true for /var/tmp cause vi temp files go there. this can only be resolved by booting from dvd or network and give the right permissions to the mountpoints. i had such an issue some month ago...
Second, tell the OS to resolve hostnames by the /etc/hosts file (default) and the domain servers you just entered by adding the word "dns" next to the "hosts: files" entry in /etc/resolv.conf:
hosts: files dns
Finally, assign yourself a static ip address and add a default route:
ifconfig vfe0 192.168.120.100 netmask 255.255.255.0 up
route add default 192.168.120.1
