IPv6 proxy streznik | squid 3.1

Posted by admin in freebsd, ipv6, Linux on January 7, 2010

Squid od verzije 3.1 (trenutno je se v beta verziji) naprej pozna IPv6 protokol in zna delati kot ipv6 proxy streznik… To je med drugim uporabno tudi na mobilnem podrocju – vecina mobilnih naprav se nima dual-stack podpore (oz ipv6 podpore), ce smo natancni, mislim da v casu pisanja samo Nokia Symbian telefoni podpirajo IPv6 dialup preko EDGE/HSPA omrezja. Tak proxy postane uporaben v primeru, da imamo na voljo samo IPv6 povezavo, rabimo pa tudi dostop do IPv4 streznikov.

Do squida dostopamo preko IPv6, ta pa nam poleg IPv6 servira tudi IPv4 sajte -> v kolikor dobi od DNSa oba A in AAAA record jasno uporabi IPv6 povezavo… Vec o IPv6 podpori v lignju si lahko preberete na tem linku…

Same instalacije se nebi dotikal, kot vedno je odvisna od platforme… V kolikor nalagate binarne pakete bi morali imeti ipv6 podporo po defaultu omogoceno, v nasprotnem primeru ne pozabite sestaviti squida s podporo za ipv6.

Nastaviti moramo sledece:

  • IPv6 nastavitev dostopovne tocke (APN) na telefonu ali
  • Nastavitev brskalnika, da uporablja proxy streznik (google it!)
  • IPv6 konfiguracija streznika

Is my GPRS/UMTS modem ipv6 capable?

Posted by admin in Aktualno, ipv6, Linux on December 22, 2009

Here is how you can check if your modem is capable of doing an ipv6 dialup… I won't get into details about how to connect to device via terminal, i wrote something similar in this post.. (Hint: M$ hyperterminal or putty, Linux and OsX minicom)

Once you are logged onto device you have to issue following command, with which you see the supported connection types: at+cgdcont=?. Here is the output from my Novatel mc990D card:

at+cgdcont=?
+CGDCONT: (1-16),"IP",,,(0-2),(0-3)
+CGDCONT: (1-16),"PPP",,,(0-2),(0-3)
+CGDCONT: (1-16),"IPV6",,,(0-2),(0-3)

If you see a third line (yes, the ipv6 one) then you are good to go.
