Help with wireless lan internet, nearly got it to work

Belize · 10-24-2003, 07:58 PM

Hi

After alot of work today, the red hat 9 is detecting the wireless lan ( eth0 ) settings and drivers correctly, and it is succesfully working.
I can ping people from my LAN, but cant do nothing in internet.
A problem I had before is my broadcast mask be 10.255.255.255 instead of 255.255.255.255 . I fixed that with adding

ifconfig eth0 broadcast 255.255.255.255

to /etc/rc.d/rc.local

I dont know what else I should change so it works, I reapeat I can ping my default gateway ( 10.4.1.63 ), my IP is 10.4.2.14 but internet doesnt work. Thanks in advance !

Did you enter DNS information?
su
neat
Enter the DNS information in the interface properties.

The kid next door configured it without entering any DNS information.

How can I check what my DNS servers are in WinXP ?

ipconfig /all in a console window.

thank you for your help but it is still not working

I entered the DNS I saw in ipconfig /all ( 10.4.1.53 ) as a Primary DNS server in the Network options, saved and rebooted. The difference is now that the error when I try to open a web page is not "Unable to contact linuxquestions.org" ( or something similar ) but is "The connection was refused when attempting to contact linuxquestions.org"

Why is this happening

I dont know if that matters but in "hostname" above the DNS options I entered the hostname of my box "Belize" and in the "Hosts" part I entered my IP "10.4.2.14". Peace

The DNS host name probably isn't causing any problem, but take your IP out of the hosts list. Put a search path in the DNS tab, which you can get from Windows with ping -a on the DNS server. (For syntax comparison, for my IP it's oc.cox.net)

After applying the changes, cat /ect/hosts to see if it's back to a simple state. Something like
127.0.0.1 localhost.localdomain localhost
You can add other hosts later, but let's get it working first.

Ok I will delete my IP from the hosts list and will check after that in /etc/hosts, but I didnt get that :

C:\Documents and Settings\Kaloian>ping -a 10.4.1.53

Pinging people.las-local.ch [10.4.1.53] with 32 bytes of data:

is search path people.las-local.ch ?

2Gnu · 10-26-2003, 03:22 PM

I think just las-local.ch, but try people.las-local.ch if that doesn't work.
I'm not even sure it's critical but I'm trying to eliminate any options. The missing DNS server info and having wrong stuff in the hosts were probably the roadblocks.

if you can ping the subnet but not the internet, it's definitely a DNS problem. i think the issue here is that you don't have your default gateway set.

to do this under slackware, issue "#route add default gw <IP of firewall/router connection to internet>". if you set the default gateway correctly, it should forward you the correct IPs for the DNSs you use to connect to the internet.

HTH,

2Gnu : I deleted the host and made sure there is nothing in /etc/hosts
It aint working.
I tried both with people.las-local.ch and las-local.ch

yocompia : I have my default gateway set - 10.4.1.63 and I use red hat, not slackware. With slackware I had problems with the drivers for the wireless lan card : os_onrico ( something like that )

Additional information - I have stopped smpt service from running on my system, if that does matter.
