   Open terminal:
   IF
   ping 8.8.8.8
   Works
   ping http://www.slitaz.org
   Fails

   Then the DNS servers which are assigned by your ISP's udhcpd server are not working.
   Your computer contacts the DNS server to get the i.p. address for a web site name query.

   The nslookup tool can be used to test the existing DNS server configuration or override by appending the i.p. address of an alternate DNS server.
   nslookup http://www.slitaz.org
   or to try google DNS
   nslookup http://www.slitaz.org 8.8.8.8

   On my machine google DNS replys with correct i.p. address for http://www.slitaz.org:
   root@slitaz:/home/tux# nslookup http://www.slitaz.org
   Server: 8.8.8.8 <= First DNS listed in /etc/resolv.conf
   Address 1: 8.8.8.8 google-public-dns-a.google.com

   Name: http://www.slitaz.org <= lookup address name query
   Address 1: 94.23.61.29 pangolin.pimentvert.com <= i.p. address with web server domain name

   The following edit will use google DNS servers instead of the DNS servers assigned by your i.s.p.

   su, password: root
   # leafpad /usr/share/udhcpc/default.script
   Add what's in bold:

   #!/bin/sh

   # udhcpc script edited by Tim Riker
   dns="8.8.8.8 8.8.4.4"

   [ -z "$1" ] && echo "Error: should be called from udhcpc" && exit 1
   ...

   leafpad=>File/Save/File/Quit
   Restart networking:
   # /etc/init.d/network.sh restart

   Rerun ping test

   Thanks for your help but it doesn't ping at all despite that eth0 says that it receives packets . i did what you said and it didn't work and it gave me that

   The i.p. address assigned to eth0 inet addr:192.168.77.246 is not used on the internet,it is for Local Area Network only.
   Is this computer directly connected to a cable/dsl modem or is there a router between it and the modem?
   If your connected to a router that assigned the i.p. address can you ping the router ?
   Post output from this command:
   route

   Your output of route has no default gateway which should be the router i.p. (192.168.77.1)
   The gateway is the LAN i.p. of the computer or router that provides access to the internet or another network.
   My slitaz(192.168.1.2) is connected to a wifi router(192.168.1.1) which connects to the cable modem(internet).

   Output of route:
   tux@slitaz:~$ route
   Kernel IP routing table
   Destination Gateway Genmask Flags Metric Ref Use Iface
   default 192.168.1.1 0.0.0.0 UG 0 0 0 wlan0

   192.168.1.0 * 255.255.255.0 U 0 0 0 wlan0

   The router's dhcpd is supposed to configure the clients gateway,DNS,mask,broadcast in addition to assigning the i.p. address.
   I would power off/on the router to reboot it, then restart network.sh

   Also, worth checking the dhcp server settings in your router....for example if you are using a more advanced router you are expected to provide all values, like the default gateway, for the dhcp server process running on the router. Perhaps it will be useful to give more details of your network and make and model of the router you are using.

    thanks for your help but the problem still exists.i can access the internet in windows but not in siltaz.In siltaz I can ping the dhcp server 192.168.77.1 but i can't ping the default gateway 3.3.3.3 and i can't ping any other site.The machine identifies dns servers .
    siltaz network begins with wlan which is idle and i change it to eth0 and it receives packets but doesn't access the internet

    Figure out the network configuration of windows which connects to the internet and you will figure out how to connect slitaz.

    i can access the internet in windows but not in siltaz

    If a windows computer running on the same network connects to the internet you should be able to copy the windows network configuration to slitaz so it connects to internet from the same network.
    Windows: paste the output from ipconfig /all into your Reply
    start/run
    type cmd in run box
    click ok button opens windows terminal
    In terminal type:
    ipconfig /all
    Hit the Enter key
    Place the mouse cursor in the terminal window,left click mouse button
    Right click mouse choose Select All from menu
    Left click with mouse cursor in Slitaz forum Reply/Post: box
    Right click mouse choose Paste
