Konqueror works but firefox or opera doesn't!


I have just installed Suse 9.3 as a Linux newbie and have been plesently suprised. Just got a few minor hitches!

I am currently using Konqueror browser and KDE desktop to surf the web. However if I open Firefox or Opera, they both report immediaitely that any site I try a connection could not be made. I tried changing the connection settings in Firefox but to no avail. I am connected using a shared local network, with a dlink router.

Any tips would be much appreciated as I really like the firefox browser :->

Many thanks but not quite there

Thanks for the reply much appreciated. Ok these are the answers I can give to your questions.

Do you need to configure any proxy? No I don't use a proxy, my computers a wired to a router which also acts as a DHCP server, correctly assigning addresses.

What happens when you run 'ping www.google.com'?

I receive the ping packets happily from www.google.com

What do you have in /etc/resolv.conf? This is what is contained in resolf.conf

### BEGIN INFO
#
# Modified_by: dhcpcd
# Backup: /etc/resolv.conf.saved.by.dhcpcd.eth0
# Process: dhcpcd
# Process_id: 6043
# Script: /sbin/modify_resolvconf
# Saveto:
# Info: This is a temporary resolv.conf created by service dhcpcd.
# The previous file has been saved and will be restored later.
#
# If you don't like your resolv.conf to be changed, you
# can set MODIFY_{RESOLV,NAMED}_CONF_DYNAMICALLY=no. This
# variables are placed in /etc/sysconfig/network/config.
#
# You can also configure service dhcpcd not to modify it.
#
# If you don't like dhcpcd to change your nameserver
# settings
# then either set DHCLIENT_MODIFY_RESOLV_CONF=no
# in /etc/sysconfig/network/dhcp, or
# set MODIFY_RESOLV_CONF_DYNAMICALLY=no in
# /etc/sysconfig/network/config or (manually) use dhcpcd
# with -R. If you only want to keep your searchlist, set
# DHCLIENT_KEEP_SEARCHLIST=yes in /etc/sysconfig/network/dhcp or
# (manually) use the -K option.
#
### END INFO
nameserver 192.168.1.1


What is the output of 'route'?

I'm not really how to complete this in Linux....still learning!

What is the output of 'ifconfig'?

Does the lynx browser work?

How do i run lynx from the command line, what command is needed?

What happens when you run 'telnet www.google.com 80' and type 'GET / HTTP/1.0<enter><enter>'?

Now this is a strange result!

paul@linux:~> telnet www.google.com 80
Trying 1.0.0.0...
telnet: connect to address 1.0.0.0: Network is unreachable

Why is it trying 1.0.0.0... ?

Any more help would be so grateful, its just weird that Konqueror can browse the internet fine!!

Note: you may not have lynx installed. If you don't have it, no need to bother installing it, it probably won't work...
Note that there are several equivalents to lynx. Links and elinks provide roughly the same functionality, you may wish to look for them if you can't find lynx.

What happens when you type 'nslookup www.google.com<enter>' at the shell prompt?

The problem is your computer is looking at nameserver 192.168.1.1 to resolve the DNS lookup. Your /etc/resolv.conf should have the info from your router.

Something simliar to:
search xxx.charter.net
nameserver 24.xxx.xx.5x
nameserver 24.xxx.xx.5x

Look in your router at the DHCP settings and copy them to /etc/resolv.conf

Nameserver 192.168.1.1 is good. Most modren routers act as nameservers also, forwarding requests to the real nameserver, and, since the file was generated by dhcp, it means that it's what the router has sent to the client. Also, a wrong resolv.conf would have meant that ping would have failed. Don't modify resolv.conf before performing the test with nslookup to see if that's the problem. If the output of 'nslookup www.google.com' is something like this, there is no problem with resolv.conf:
Code:
Server:         192.168.1.1
Address:        192.168.1.1#53

Non-authoritative answer:
www.google.com  canonical name = www.l.google.com.
Name:   www.l.google.com
Address: 72.14.207.99
Name:   www.l.google.com
Address: 72.14.207.104

Hey there, many thanks for trying to help me here, I am picking up Linux quite quickly and really becoming more ofay with it! Even got DVD playback and the Nvidia graphics drivers finally working!

Right here are some of the results I gained:-

NSLOOKUP

linux:/home/paul # nslookup www.google.com
Server: 192.168.1.1
Address: 192.168.1.1#53

Non-authoritative answer:
www.google.com canonical name = www.l.google.com.

Address: 66.102.9.104
Name: www.l.google.com
Address: 66.102.9.147
Name: www.l.google.com
Address: 66.102.9.99

ROUTE

linux:/home/paul # route
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.1.0 * 255.255.255.0 U 0 0 0 eth0

loopback * 255.0.0.0 U 0 0 0 lo
default mygateway.ar7 0.0.0.0 UG 0 0 0 eth0

IFCONFIG

linux:/home/paul # ifconfig
eth0 Link encap:Ethernet HWaddr 00:0B:6A:28:69:18

Now I have discovered that is only external software that doesn't work, Konqueror & Kmail work fine. However I tried Firefox as you know and also Thunderbird, and Thunderbird does not work either. Opera doesn't work as well. Why would the inbuilt programs work and the external ones not? I have reinstalled the sytem on numerous occasions so I have ruled out a faulty install. I also tried the Lynx browser and that does not work either.

Anymore light on the matter would be fantastic

Many thanks

Paul

All your settings seem fine. Try to disable ipv6:
Code:
echo "alias net-pf-10 off" >> /etc/modprobe.conf
modprobe -r ipv6

Hello Stefan,

Finally got round to trying your suggestion of turning of IPv6 and that has worked a treat. I can now use Firefox quite happily.

Many thanks for all your help.

Hello, I have been following this thread because I have a similar problem. I would like to disable ipv6 also but when I issue the 'modprobe -r ipv6' command I get 'FATAL: Module ipv6 is in use.' I am in runlevel 3. Do i have to shutdown the network service first?

Well I answered my own question. I shut down all networking services and it still gives the error 'FATAL: Module ipv6 is in use.'

So I went to runlevel 1, single user mode and tried to do the modprobe -r ipv6 and I still get the error above. Any suggestions?

You can manually edit /etc/modutils/alias and uncomment
alias net-pf-10 off
To disable Ipv6

This was handy, but still did not solve my situation, which is exactly as described in earlier posts.

I DID solve it though, by going to my router (D-link 604T) and under DHCP settings switching DNS mode from Manual (192.168.0.1) to automatic. Hooray, firefox now works.
Can anyone explain why this setting would have preventing firefox from browsing, but konquerer was OK?

BTW typing open:config did not work for me, but about:config did. Thanks.
