Mit der Linuxdistribution fli4l kann man in wenigen Schritten einen Linux-Router samt Firewall einrichten.
- Download der Software im Download-Bereich
- Falls DSL / ISDN, etc. erwünscht wird, ebenfalls downloaden
- Entpacken des Basissystems
- Entpacken der zusätzlichen Pakete. Wichtig: die Zusatzpakete müssen ins Hauptverzeichnis des Basissystems entpackt werden
- Wenn alles ordnungsgemäß entpackt wurde, steht im Config-Verzeichnis neben der base.txt die anderen Textfiles der Zusatzpakete
- Konfiguration von Linux über die Base.txt im Config -Verzeichnis.
Abbild der Base.Txt
- Wichtig: Mit # werden Einträge deaktiviert.
- Habt Ihr mehr als eine Netzwerkkarte, muss dies im Bereich "Ethernet Card Drivers" angegeben werden.
- Einfach die zwei Netzwerkkarten auswählen und bei der zweiten Karte die Bezeichnung ETH_DRV_1 in ETH_DRV_2 umbenennen.
- Etwas weiter unten die Bezeichnung ETH_DRV_1_OPTION='' kopieren und eine Zeile weiter unten einfügen und die eins durch eine zwei ersetzen.
- Im Bereich "Ether networks used with IP protocol:" die ganzen Einträge außer IP_ETH_N='1' kopieren und dort nochmals einfügen und aus der 1 in der Namensbezeichnung eine Zwei machen.
- In dem Eintrag IP_ETH_N='1' die Eins durch eine Zwei ersetzten.
- Falls eure Netzwerkkarte nicht in der Treiberliste verzeichnet ist, nachprüfen, ob die Netzwerkkarte mit Windows 2000 kompatibel ist.
- Dann einfach diesen Treiber auswählen.
- Die restlichen Konfigurationen sind meiner Meinung nach selbsterklärend, wie etwa Name des Routers, Passwort, IP-Adresse,etc.
- Am Schluss noch eine leere Diskette ins Laufwerk und auf mkfloppy.exe klicken.
- Nun wird Linux auf die Disk kopiert.
- Das waren die wichtigsten Kernpunkte. Eine Alternative zu der Base-Konfiguration stellt das Programm fliwizNG dar, mit welchem man Linux unter einem Installationsassistenten konfigurieren kann. Ob dieser allerdings genauso viele Einstellungsmöglichkeiten bietet, kann ich leider nicht sagen.
