I've got a weird Problem:
On my newest Laptop some websites are not displayed.
I tried it with firefox and konqueror. On another laptop in
the same net these sites are displayed correctly.
On the new laptop, the host names are resolved correctly,
I can telnet to the undisplayed websites, but I don't get no
answer. From the new laptop I can login to both the old
laptop and the firewall machine.
Technical Details:
websites I can contact: eg. http://www.wohin-heute.at/
websites I can not contact: eg. http://www.gmx.de
Firewall: OpenBSD 3.3 with packet filtering
(Logs do not show anything I can relate to the problem)
no DNS server running, ppp connection via DSL
New Laptop: OpenSuse 10.2, Firewall completely
disabled, default route to the firewall machine,
no proxy for firefox ('direct connection to internet') and in yast
can ping and telnet to www.gmx.de (on port 80) but gets no
answer (the same is true for wget).
Old Laptop: Suse 10.0, default route to the firewall machine
works without problems
As I can ping all websites, this is not a problem of DNS, right?
As I can see the websites on another laptop in my local net,
this is not a problem of the firewall, right?
As I can't see the websites in both firefox and konqueror,
this is not a problem of firefox, right?
As I can see some websites, this can not be a problem of
firewall port 80 or wrong proxy, right?
As I do not get an answer from www.gmx.de on port 80
via telnet (but I get the connection!), this can not be a
problem of 'web 2.0' features the browser may not
support, right?
So I currently have the Problem: where should I start searching?
I found a hint in the opensuse faq (proxy setttings and ipv6 settings),
I tried both, no effect.
Could this be a problem between (older) OpenBSD and (newer) Linux?
Any Ideas?
thing 'autodetect' network settings? Maybe it's not a 'direct
connection' to the internet but more of an 'access the internet thru a
LAN' connection? The networking HOWTO in ldp.org (linux documentation
project site) may be more helpful in this regard; I remember there is a
list of questions or faqs there that could narrow down your problem, to
help you move forward on this.
