Hi, Im running a SuSE 10.0 on my server. I've created the following files: /etc/sysconfig/network/ifcfg-sixxs /etc/sysconfig/network/ifroute-sixxs Content of the file /etc/sysconfig/network/ifcfg-sixxs STARTMODE='onboot' BOOTPROTO='static' TUNNEL='sit' TUNNEL_LOCAL_IPADDR='81.169.139.240' TUNNEL_REMOTE_IPADDR='212.224.0.188' IPADDR='2001:6f8:900:bfa::2/64' TUNNEL_TTL='64' Content of the file /etc/sysconfig/network/ifroute-sixxs default 2001:6f8:800:1003::2 Finally i did enter the command "ifup sixxs" and the output was: ERROR: Interface sixxs is not available Whats wrong here? Thanks in advance for your reply... Yours Faithfully Marco Weber
