--mYCpIKhGyMATD0i+ Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Content-Transfer-Encoding: quoted-printable hello all, i've got a project in the works to build a roaming wireless extension to freebsd. basically my idea is to use the concept of restricted "wardriving" (http://www.dis.org/wl or http://www.wardriving.com) to provide a continuous network experience. basically the rationale is as follows: since each open wireless LAN (like the NYCwireless.net nodes) has its own internal IP setup and is not organizationally associated with any other node, it's hard to keep a persistent network session open. a telnet session, for instance, would be reset upon moving to a different WLAN. we could maintain that session with a tunnelled connection from the internal WLAN to a central server, then use NAT-like behavior to translate outgoing and incoming connections to the proper source and destination addresses. between the server (the host doing the NAT part) and the client that connects to the main server, we should tunnel. but let's say that all protocols but TCP are blocked (as is sensible for a public-access point). we need to tunnel through TCP or some other allowed protocol. =20 my question is as follows: i'm thinking of using the tun(4) interface to do the tunnelling, but i wanted to see if anyone had other suggestions. given that this is the -mobile list, what recommendations might people have on tunnelling in a mobile manner? if you want to read more about this project, take a look at http://www.cerastes.org/projects/roaming.html where i have some initial planning stuff posted. -cerastes --=20 crotalus cerastes And the LORD sent fiery serp= ents cerastes@cerastes.org among the people, and they b= it =20 for gnupg public key, see: the people; and much people = of http://www.cerastes.org/~cerastes/pubkey.gpg Israel died. -- Numbers 21:6 --mYCpIKhGyMATD0i+ Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.0.6 (FreeBSD) Comment: For info see http://www.gnupg.org iD8DBQE78JZfThhQtDsQTOwRAgCZAJ0f2ADIiXta68l1KwlnP2OXGHsiMACff+RN WX2+hyJkyY2chmsngGvCTRE= =7owS -----END PGP SIGNATURE----- --mYCpIKhGyMATD0i+-- To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-mobile" in the body of the message
