When you try to access a Web site, or any remote site, you need to specify the full hostname. This means the machine name plus the domain name:
lynx my.yahoo.comIf you have a few domain names that you access a lot, you can make your life easier. You can edit/etc/resolv.conf and add the domains there:
search domain.net yahoo.com This means that the system will search in those domains for hostnames. From now on type: lynx my The system will now look for "my", if that hostname doesn't exist it will look for "my.domain.net", and at last "my.yahoo.com".
