Too much problems to connect

English Network/Internet
#1

Since a few days ago, I have too much problems to connect.

When I try to connect to Internet with Firefox, the following message is printed out (, most of the times):

Unable to connect
Firefox can't establish a connection to the server at www.google.com.ar.

Also, I have problem to update openSuse:

PackageKit Error repo-not-available: Failed to download /content from http://download.opensuse.org/distribution/11.3/repo/non-oss/

I suspect an update make the system bad, because on Windows system no problem exist about Internet connection, so hardware is OK.
I also re-install openSuse 11.3, an d the same problem persist.

Thank you for any help.

The fact that one program (FF) is not able to connect to one HTTP server does not mean that you have no connection to the internet.
Did you try other HTTP servers (like these Forums, did you post this with the system or did you have the same sort of problem)?
Did you try another browser like Konqueror?
What about other internet traffic, like do you get mail from yout IP (only when you do use that of course).
Does DNS lookup function (try nslookup forums.opensuse.org).

#3

Indeed, like Henk says: no internet connection.

How do you connect? Wired / Wireless?
Laptop or desktop computer?
What did you install from ?

Start Yast, Network, Network devices, and see if networkcard(s) is/are detected and configured.

I’m connected through a router through a wired connection.
I had checked the network settings. (Static IP). Everythings seems be OK.
As a matter of fact, I just reinstalled openSuse, and all updates were OK, but after last reboot (on installation), some times when I try to connect to Internet I recive:

Unable to connect
Firefox can't establish a connection to the server at www.google.com.ar.

and when I want to update the system through Yast, I recive:

Download (curl) error for 'http://packman.inode.at/suse/11.3/repodata/repomd.xml':
Error code: Connection failed
Error message: couldn't connect to host

Some times I can’t connect to Internet, the most of the times.

Recall, hardware it’s OK. (From Windows OS, I can connect to Internet normally.)

Thank you, for your help.

Use the following cpmmands to help determine the differences between when you have a working connection and a failed one:

cat /etc/resolv.conf

/sbin/route -n

If nothing obvious here, it may be the router thats the issue.

#6

OK.
I reinstalled openSuse 11.3.

resolv.conf file:


### /etc/resolv.conf file autogenerated by netconfig!

# Before you change this file manually, consider to define the
# static DNS configuration using the following variables in the
# /etc/sysconfig/network/config file:

And this is my routing table:

Now, I can’t connect to Packman repo, in order to download “restricted formats”.

No. I changed this morning to another mirror due to that one being down.

I beg your pardon.
How can I change the mirror? Which is its URL?
I’m trying to connect to Pakcman repo to download “restricted formats”, through “one click” installation.

Thank you.

#9

Thank you!
I just change the mirror of packman repo.
I can get fine the restricted formats.

Thank you very much!

#10

When you can get to any Packman repo, you have Internet connection. Thus I guess that your original problem is solved.

#11

That’s not true.
Several times, while I download restricted formats, I recived “connection refused” message, then I tried again and again, until download was completed.

The problem remins the same.

#12

Thus it is intermittent. Those are the peoblems most difficult to solve :frowning:

Do you have this only on particular sites. E.g. when you browse through these Forums, doo you have problems? And other sites, either browsingg or doing othet things like downloading?

You say:

Do you really have a working DNS from 192.168.1.1 ??? Test it with

dig @192.168.1.1 www.google.com

What happens when you edit /etc/resolv.conf and put in

nameserver 8.8.8.8

instead?

#14

As I said in the start of this thread, I have problems to browse any site: Some times I can connect… some times I can’t.
Most times that I can’t connect, when I reload the same URL I can connect. It is like the first time I want to reach a site, the browser fail to connect, but the second o third time may be it connect to the site.
Also, some times the sites are loaded with problems: only text loaded, no formats, and so on.
It’s very strange problem.

#15

I’m sorry but I can’t test now: I’m at work.

About DNS, I have my box behind a router (192.168.1.1), and so it did work fine too much time.
Other machines (running Windows, with primary DNS 192.168.1.1) are behind the same router, and they can connect normally.

Thank you.

I do not know anything about windows or how it works (and I don’t care), but I bet a sixpack of beer that the contents of your file /etc/resolv.conf are just plain wrong and that this is the cause of your problems. Let’s see what happens when you fix it.

vodoo:
