iface eth0 inet dhcp
* If you are behind a firewall inside a 'Corporate Network', the following 2 files may need to be edited to according to your Coporate settings:* Edit your /etc/resolv.conf file and have something similar to this: Remove the "<><>" symbols and replace by your own corporate DHCP and DNS servers adresses. domain <<something.dhcp.mycompany.com>> search <<something.dhcp.mycompany.com>> nameserver <<IP address of your DNS server 1>> nameserver <<IP address of your DNS server 2>> * Add the proxy settings: In your /etc/environment file, add something similar to this using your own corporate proxy server address and port number:
http_proxy="http://myproxy.ext.mycompany.com:80"
https_proxy="http://myproxy.ext.mycompany.com:80"
ftp_proxy="http://myproxy.ext.mycompany.com:80"
no_proxy="localhost,.mycompany.com"
