Some pages not loading in Iceweasel (Debian 5.0)


I have done a fresh install of Debian 5.0 just a few days ago(on my office PC). Unfortunately, when i try to access our backoffice (through a regular connection; the server is located abroad) , Iceweasel just keeps loading and finally tells me the connection has been dropped or that i received a time-out.. When i start Iceweasel, Google loads fine as do many other sites. Using Synaptic, i already installed/checked for Flash and Java-support (our site uses jsp, which made me think it was because of missing plugins/SDK's/etc.) Still, nothing has solved my problem. I love Debian (though perhaps less knowledgable) and my install of it in the office has put me under the microscope; everyone's sceptic, and this isn't making me, nor Debian (or Linux in general) look any better! Is there anyone who can help?

I can also tell you that i had done a earlier install of Debian. Before following my brother's "advice" of "upgrading" to unstable, i had no problems. Even after that, nothing was wrong. When unstable proved to be too unstable for office use, i did a fresh install; i've had the problem ever since..

I would be very grateful for any insight and/or advice!

John.

Welcome to LQ!

If other sites are loading fine then I'd say that a problem is in the server,it's maybe too busy.Can you ping it?You can try to connect with IP address of the server in the navigation bar of Iceweasel if you haven't tried that already.
There is no proxy,right?

There is no proxy (and i've set up Iceweasel as such). Ping does work, and the server's fine (collegues on Windows-boxes have no problems).
I have the same problem with, for instance, facebook and hotmail..
Navigating to the IP-address has the same result..

p.s: thanks for taking the time to reply, alan_ri

Do you have the same problem with other browsers?
opera...

try to disable ipv6 in iceweasel

Code:
type
about:config in the addresbar
type ipv6 in the filter field.
high-light network.dns.disableIPv6 by right-clicking it, and change the value from false to true using Toggle.

Will try in a bit; will have to wait 'till the boss is out of the office (poor sod actually thought i'd have to install Debian every day, and is extremely sceptical). Will report back the result as soon as i have it.
Would it be wise to switch off IPv6 completely, and not just in Iceweasel?

for that, in /etc/modprobe.d/aliases i'd change

Code:
alias net-pf-10 ipv6
to

Code:
alias net-pf-10 off
alias ipv6 off

right?

Asking 'cause others have written you should comment out the existing line, and add 3 others, resulting in:

Code:
#alias net-pf-10 ipv6
alias net-pf-10 off
alias ipv6 off
alias net-pf-10 ipv6 off
Wouldn't both result in the same?

thx again for the quick and friendly help!

COrrect, disable IPv6 altogether and also in Iceweasel.

For sites like hotmail you need to change the user.agent in about:config to Firefox.

Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.0.8) Gecko/2009032811 Firefox/3.0.7 (Debian-3.0.7-1)

i've done all of the above, to no avail..
Our backoffice gives me:

Quote:
Connection Interrupted

The connection to the server was reset while the page was loading.

The network link was interrupted while negotiating a connection. Please try again.
Facebook and hotmail (by now my benchmarks for a working browser) fail to load (hotmail does read "Sign in" and shows the favicon)...
I am completely at a loss; other sites (like this one!) work normally..
JRE (and even JDK) are installed, IPv6 is disabled at system- and browser-level and i've installed the User Agent Switcher (which, i'd like to note, i didn't need when i first installed Debian (same disc used) 2 weeks earlier.. Everything worked as it should no longer than 2 weeks ago!

Got any other suggestions?

p.s: my first install seemed to have gone a bit different than the 2nd, now that i think of it.. Gnome wasn't install right away; i only had TWM. I fell back to a terminal and installed Gnome from there, then opened Iceweasel (afraid it might not work) and was relieved when it did. Seems to be an "either/or"-case; either a flawed install but a working browser, or a flawless install and (a) non-functional browser(s)..?

Do you have the problem when you use opera, firefox...?
Try to install firefox, and see if the problem persist.

I've installed Firefox and was faced with the very same problem. Wether i use Iceweasel, Firefox, Opera, Epiphany or (when i log in to KDE) Konquerer; i just can't reach the necessary site(s).. Strangely, when i look at the network manager, it still says IP6/IPv6 everywhere, despite the changes made in /etc/modprobe.d/aliases.. Just guessing it shouldn't say that..

And i just can't figure out why, why, why i didn't have this problem the first time! With the first install, i did nothing, changed nothing and edited nothing and it (still) worked just fine out of the box!? The 2 discs i used originate of the same ISO-file (downloaded with torrent), so can't be different; they checked out fine, MD5-sum was ok, etc. etc.

What could be so different this time?

thx again for the help so far, guys.

what are the MTU setting?
Can you give the output from
Code:
ifconfig
Could you compare the MTU with those on the windows machines?

Can you restart your router/modem,or can you change your DNS server?
If you can't,install nscd then run modprobe nscd,reboot and then run /etc/init.d/nscd restart as root.
Please post if you can load those sites then.

Will try those on monday (tomorrow).

Just one question: alan_ri, what will that do?

Debian says:
Quote:
You should install this package only if you use slow Services like LDAP, NIS or NIS+
But i don't use those, so.. ...?

(don't wanna be paranoid; i just like to know what i'm doing to my box!)

A shot in the dark here, but check out this thread:

http://www.linuxquestions.org/questi...hlight=springs

and try the *fix* explained in post #6.

It certainly worked for me on a few sites I was having trouble with, and I've had no trouble with any other sites since.

cheers,

Nscd is a deamon that provides a cache for the most common name service requests,so when you restart it it will flush DNS cache and this might be necessary becuse maybe in that cache are wrong entries for certain sites.Please read man page for it.
Don't worry,if it ain't workin just run: modprobe -r nscd.
Mark nscd for complete removal in Synaptic and remove it.
