browser problems
![[nl]](/s/countries/nl.gif) Shadow Hawkins on Thursday, 22 January 2004 22:18:40
I have 2 win xp machines behind a debian router, both on the same subnet. Both machines get their ipv6 address from the debian router. Pinging www.sixxs.net works on both machines fine: both get replies from the ipv6 address of www.sixxs.net. The problem is that one machine is able to browse to www.sixxs.net (and other ipv6 page) en the second is not.
When I use Internet Explorer at the second machine, I get a kind of time-out after a while. Netstat gives as "State" always "SYNC_SENT 0".
When I use Firebird 0.7, I get immediately "The connection was refused when attempting to contact www.sixxs.net"
When I use telnet (telnet www.sixxs.net 80; get /), I get a lot of html.
So I think some application is blocking my browsers in someway, but I have no clue which one. I used the search and found some problems with antivirus software, so a disabled (exiting was not possible) Norton Antivirus '03 (runs on both machines, so could not be the problem), this makes no difference. Another problem found was with netlimiter, which indeed was used by the machine with no ipv6 browsing and not by the other one, but uninstalling and rebooting makes not difference.
The processes that were running are (using pslist from sysinternals):

Has anybody an idea what is going wrong?

Start deinstalling Norton it is a bad virusscanner anyways, but the worst part is that it installs itself in between the layers of winsock disabling the working of the IPv6 stack in some parts.
Also you should check, using eg ethereal, if there is any communications being sent onto your network card.

Norton was not really the problems, worked on the other machine too.
I made the stupid mistake to restart the win xp only once after removing netlimiter.. After restarting the machine again everything worked fine..
So netlimiter is a bad program, when using ipv6. I had not rules defined to limit something, I exited the program, but that is not enough, it must be completely removed.

Then they fixed Norton apparently as it was one of the programs that was causing problems, good to hear.
Does the netlimiter application understand IPv6 then ?

No, it does not, and I'm afraid that is the problem. Netlimiter has to do "something" with the winsock, to be able to limit the speed of every application, so I guess that there is the problem. (But it is strange that trying to get an ipv6 www page by telnet is possible, while netlimiter is installed).
