Exclamation HELP!!! Internet connection LOST


Could someone please help me before I start chewing my wrists!!!!

I am trying to configure my Linux PC on my home network, to act as a proxy to the internet.

After I configured samba (I have windoze clients), and played around with the network settings, I dial into my ISP (ppp0). The problem is that even though I am connected (logged in) I cannot browse the net (using lynx). I don't know what I have done!!!!
I cannot ping the internet?

My local network is working fine. My internet WAS working.

It seems like when one thing is working the other won't!?!

Please help me!!!

Assuming you are using a 56k modem, run wvdial in a root window.

What does it say?

You are correct!

Yes, External 56K modem.
Yes, I connect using wvdial.

wvdail dails, connect, send username, sends password, tells me I am connected.

When I run lynx, I get:

Alert! Unable to connect to remote host.

Your /etc/resolv.conf should looke somethng like this:


------------- /etc/resolv.conf ----------

search your_isp_domain.com
nameserver 111.111.111.111
nameserver 222.222.222.222

This looks good, my guess is it's just your resolv.conf that needs fixes.

As far as the LAN which is a private network (and never sees the light of day) you should give it domainame mine for istance is homelinux.net?

Check man resolv.conf but I believe you could do somtihng like this:


-------------- /etc/resolv.conf ------

domain homelinux.net
search yourisp.com
nameserver 111.111.111.111
name server 222.222.222.222

Needless to say check with your ISP to get list of DNS servers.

Unhappy Still not working!!!

Hi I added the DNS settings to my resolv.conf, but I still can't browse!!!

When I open lynx it looks like it is searching but after a while it gives a error:

Looking up www.google.com
Unable to locate remote host www.google.com
Alert!: Unable to connect to remote host.

lynx: Can't access startfile http://www.google.com/

During the time it is looking for the page, there is a lot of activity on my hub, but nothing on my modem!!!!?!!!?

Could someone explain this??

This is a bit of a long shot but he it goes:
Check which port your plugged into.

Login in with user accouint:
$ su - root
# netconfig

Us a static ip address of 192.168.0.port_number

# ifconfig eth0 down
# ifconfig eth0 up
# ifconfig eth0

# ping dns_for_your_isp
# ping something_else
# traceroute dns_for_your_isp


Also netconfig overwrites /etc/resolv.conf, so you'll have to enter the dns info again.
