yazılanları iyice okudum fakat şunu anlayamadım. dizüstü bilgisayarda wireless ile giriyorum. masaüstü bilgisayarıma hub yardımıyla internet bağlamak istiyorum. sanırım burada bilgisayarlardan birisinde iki adet ethernet kartı var. o yüzden işlemleri tam olarak anlayamadım .benim yapmak istediğim ise şöyle;

dizüstü wifi ile internete bağlı, dizüstüne taktığım bir adet network kablosu huba dağıtıcı soketinden bağlı, bir sokette de masaüstü bilgisayarıma bağlı olan ve ethernet girişine giden kablo var.

wirelessdan gelen interneti hub üzerinden masaüstü bilgisayarıma bu dediğiniz işlemleri yaparak bağlayabilir miyim? teşekkür ederim.

her nedense beceremedim. söylediğiniz işlemleri internetini paylaştırmak istediğim bilgisayarda yaptım. fakat diğer bilgisayarda herhangi bir işlem yapmadım. sonuç ise ethertnet kartına bağlanamadı. internetini paylaştıracağım bilgisayar da ethernet kartına bağlanınca internete bağlantıyı kesti. windowsda ise interneti ubuntuya paylaştırabiliyorum. bu işlemi ubuntu da yapamamak ise beni sinirlendiriyor.

This life is not the real thing.
It is not even in Beta.
If it was, then OpenBSD would already have a man page for it
