Since two days I am not able to connect to the internet with my second
computer. This happened quit sudden as I found out when I wanted to make a
zypper dup. Kmail and Chromium do not connect to the net.

The strange thing is that the Skype which I run on that machine still
works
perfectly.
I have checked my internet setup but did not find anything that was
changed. The firewall was not changed and is still open for my
connections.

Anybody with an idea where to start looking?

The things to check are the routing table with 'route -n', the nameserver
setup with 'cat /etc/resolv.conf | grep -v \#', and pings to the various
levels.

Dear Lary,
Thanks for the help.

# route -n
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
0.0.0.0 192.168.1.1 0.0.0.0 UG 0 0 0 eth1
192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1

# cat /etc/resolv.conf | grep -v \#
nameserver 8.8.8.8


The routing table should look something like:

Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use
Iface

0.0.0.0 192.168.1.1 0.0.0.0 UG 1024 0
0 wlp4s0
192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0
wlp4s0

For this example, try to ping the gatewiwy entry in the row with the "UG"
flags using 'ping -c5 192.168.1.1'. Substitute the address listed in your
routing table. If that works, then try 'ping -c5 216.83.154.106'. If that
works as well, then try 'ping -c5 www.samba.org'. Let us know the output of
the commands in my first lines, and the ping results.

Although my problem seems to be solved after I changed the /etc/resolv.conf I
have a few questions.
I assume that the worker of my isp, a selfmade "expert", as he showed me how
to prevent the government to deny me the use of such sites as 1funny.com he
somewhere inserted the google address. Have looked everywhere, in my new
router, into the net setup but did not spot this 8.8.8.8

I do not understand why Skype was able to connect to the web and kmail and
chromium not.

Pinging was apart from the samba.org successful, meaning it found 192.168.1.1

Where would I insert the google addresses into my router or into the net setup
in order to sneek past the local government
