1 Jump to first page Setup Ethernet & PPP client on Laptop computer Presented by: Xuewu Cai Jianfang Wang

2 Jump to first page Project Purpose 1. Setup PCMCIA controller, let it probe correctly PCMCIA card attached on it. F 2. Set up Ethernet interface, including assign IP address, subnet mask to it. F 3. Setup PPP dialup client, write a script program using AT command set to dialup. Configure pppd to setup PPP interface.

3 Jump to first page Contd (purpose) n 4. Choose proper route for 2 interfaces above including default router, local subnet route,etc.loopback interface route.

4 Jump to first page Configureation Steps n Ethernet card, Modem,etc are installed onto laptop computer by PCMCIA controller as PCMCIA card. n PCMCIA card can include ethernet card, modem, memory card, serial card,SCSI&IDE card,etc. n PCMCIA support should be compiled into Linux kernel

5 Jump to first page Contd (Steps) n Put system reserved I/O port, memory into /etc/pcmcia/config.opts, in out project,parameter is : F I/O Range: 3E0-3E1 F Memory Range: D8000-DBFFF n Current release contain drivers for all the devices. All these drives are loaded as modules on linux. n When system(socket driver) detect the availability of pcmcia card in socket slots, it will run corresponding shell program under /etc/pcmcia to bring up interfaces. n Ethernet card will run network, modem will run serial,etc

6 Jump to first page Configure Ethernet card n Set network configuration parameter into /etc/pcmcia/network.opts n The details of setting: IP address : 130.85.100.254 Subnet mask: 255.255.255.0

7 Jump to first page Contd (Ethernet Card) DNS1: 130.85.1.5 DNS2: 130.85.1.3 default router: 130.85.100.1 local subnet route: 130.85.100.0 0.0.0.0

9 Jump to first page Configure PPP client n Choose chat as dialup tools n Write a piece of chat script as following: ' ' ATZ OK ATDTtelno CONNECT ' ' username < user account... passwd { "@context": "http://schema.org", "@type": "ImageObject", "contentUrl": "http://images.slideplayer.com/5/1504554/slides/slide_9.jpg", "name": "Jump to first page Configure PPP client n Choose chat as dialup tools n Write a piece of chat script as following: ATZ OK ATDTtelno CONNECT username < user account...", "description": "passwd

10 Jump to first page Contd (PPP client) n Set proper route for PPP using route command. n What to disconnect PPP connection? Use command like: kill `cat /var/run/ppp0.pid /dev/console
