 Posted: Tue Apr 13, 2004 1:38 pm Post subject: Modem IP aktualisieren |
 |
|
Hallo zusammen,
ich habe meinen Server an einem ADSL Modem dran.
Nun wenn dieses Modem eine neue IP erhält, muss dies der server merken
und nachtragen. Ich habe schon davon gehört, dass man ein
Script laufen lassen kann, hat jemand einen Link, ein Howto oder ein
beispiel ??

| Du könntest tracerout nehmen um es vom server festzustellen, oder du baust es in ip-up ein, das du den Server jedesmal benachrichtigst, wenn sich die adresse ändert. |
