| {{{ Internet connection sharing in Netsukuku HOWTO |
http://netsukuku.freaknet.org/files/doc/howto/igs_howto |
| Line 4: | Line 3: |
| This document describes how to configure a Netsukuku node to share its Internet connection and how to configure another node that will use the shared connection. ----------------------------------------------------------------------------- *** Internet Gateway Search If the nodes are in restricted mode (compatibility with the Internet), they can share their Internet connection. This can be easily done, in fact, if a node X, connected to the Internet, activates the masquerading, it is possible for the other nodes to connect by setting as the default gateway their rnode which lead to the node X. This can be automated by Netsukuku itself. The node which is sharing its connection will tell to the Netsukuku daemon to masquerade its connection and to set a specific flag in the QSPN packets. The other nodes in restricted mode will automatically know their nearest Netsukuku Internet gateway and set it in their default route. For more information read http://lab.dyne.org/Ntk_IGS . *** Prerequisites The IGS code of Netsukuku depends on the IPIP tunnel code of the kernel, so if you are using Linux be sure to have the `CONFIG_NET_IPIP' option set as a module or built-in. *** How to share your Internet connection First of all modify the /etc/netsukuku/netsukuku.conf file. Set `internet_connection' to 1. Set the `internet_gateway' option to the IP of the gateway you use to reach the Internet and specify the network interface too, for example: "internet_gateway = 192.168.1.1:eth0". This option is necessary only if you don't have the default route set when you run NetsukukuD (i.e. you haven't connected yet), otherwise, leave it commented. You have also to set your upload and download bandwidth in `internet_upload_rate' and `internet_download_rate'. It is expressed in Kb/s, so if you have a line which maximum can do: 640 Kb/s in dwload and 30 Kb/s in upload, set them to 640 and 30. `internet_ping_hosts' is a list of Internet hosts which will be pinged to verify if the connection is alive, you can use the default hosts. Finally, If you want to share your Internet connection among other Netsukuku nodes, set `share_internet' to 1. ---- netsukuku.conf snip ---- internet_connection = 1 internet_gateway = 192.168.1.1:eth0 internet_download_rate = 640 internet_upload_rate = 30 internet_ping_hosts = google.com:cisco.com:sourceforge.net:dyne.org share_internet = 1 ---- snip end ---- Now you are ready to launch the Netsukuku daemon. You have just to append the -I option in the command line. For example: # netsukuku_d -i wlan0 -r -I *** How to connect to the Internet using a shared connection Just start the daemon in restricted mode, f.e: # netsukuku_d -i wlan0 -r If you have an Internet connection and you don't want to share it, you have to set the correct options in netsukuku.conf: ---- netsukuku.conf snip ---- internet_connection = 1 internet_gateway = 192.168.1.1:eth0 internet_download_rate = 640 internet_upload_rate = 30 internet_ping_hosts = google.com:cisco.com:sourceforge.net:dyne.org share_internet = 0 ---- snip end ---- If you don't your Internet connection default route will be overwritten with that of another node. }}} |
