I wasn't acutally referring to your firewall on the laptop per-say, but
the firewall at the ISP.

Well I can't ping those servers either but thats alright. I've checked
the reverse dns ptr records and they appear to be associated with the
same domain that your sending email from so I would have to assume that
these are the correct servers.

[EMAIL PROTECTED] jbanks # dnsqr ptr 3.246.10.80.in-addr.arpa
12 3.246.10.80.in-addr.arpa:
82 bytes, 1+1+0+0 records, response, noerror
query: 12 3.246.10.80.in-addr.arpa
answer: 3.246.10.80.in-addr.arpa 86400 PTR dns-adsl-gpe2-a.wanadoo.fr
[EMAIL PROTECTED] jbanks # dnsqr ptr 130.246.10.80.in-addr.arpa
12 130.246.10.80.in-addr.arpa:
84 bytes, 1+1+0+0 records, response, noerror
query: 12 130.246.10.80.in-addr.arpa
answer: 130.246.10.80.in-addr.arpa 86400 PTR dns-adsl-gpe2-b.wanadoo.fr

And a "whois" for "wanadoo.fr" reflects that they have acouple of name
servers as well of which are different ip's from the ones you gave me.
Those are unpingable as well.
****************
nserver:     ns.wanadoo.fr 193.252.19.10
nserver:     ns3.wanadoo.fr 80.12.255.152
nserver:     ns2.wanadoo.fr 193.252.19.11
****************

But since you can get out to the internet when logged in as root but
not as a normal user points to some kind of mis-configuration issue on
the laptop in question I believe.

Do you have another computer that you can connect with that doesn't
have "Squid" or a "firewall" installed on it?? Please try that. This
will help further isolate where the problem is. I use a MS Windows
machine for just this diagnosis.

Are you actually dialing up via a phone line or are you using ethernet
connected to a cable modem and then the cable modem connects to the
ISP?? 

Kindof curious because I had a work laptop that I would take home with
me. When I was at work, I used a pcmcia nic card and then when I would
come home I would have to dial-out using a regular RJ-ll phone line
connected to the laptops internal modem. 

Two strange things happened.

1) One of the things that would happen is that first I would have to
make sure that eth0 was completely shut down or have the nic card 
ejected when I dialed up or my laptop would try and route everthing
through eht0 instead of ppp0.

2)My ect/resolv.conf would have my work dns server ip's listed above
the dns server ips that I would get from the ISP once connected. So I
would have to manually remove my work dns server ips so that only the
ISP's were listed.

If you can't get out to the internet with a differnet computer then I
would suggest installing "Ethereal" packet sniffer. I would actually
suggest installing this anyways. This can help diagnose connectivity
issues very quickly. Atleast give you a better idea of whats happening.
If you need help on how to use Ethereal after you get installed just
let me know what your questions are and I will try and help.

But after everything that you've told me so far, I would have to say
that your laptop and linux are misconfigured some-how some-way. As much
as I hate MS Windows, this is one of the reasons that I still keep one
on my lan to test connectivity issues with. I'm by no means a linux pro
and have messed up my internet access more than a few times
misconfiguring linux. It doesn't take much. So I literally have a
Windows machine that I only turn on and use when I've messed something
up on linux, and I can use it to isolate whether or not its a linux
issue or a linux admin booboo.. 9 times out of 10 it's a linux
misconfiguration or something that I've overlooked... :D

HTH's,
JBanks
