host command works, browsers do not.

Post by Michael Go » Sun, 13 Jul 2003 08:01:35


In addition to the stuff below, I just found out, courtesy of Jim Fischer,
that the "host" command does resolve the FQDNs! It only seems to be an
issue with browsers and only when it is hooked up to the router - very
curious.

Any help would be appreciated - Thanks!

MG



I am using RH9 and I just got a server set up on my home network. The
problem I am having is that I connect to the Internet via DSL, and the DSL
is hooked up to a Dell 1184 wireless router (which I reset). The RH9 box is
hooked directly to the router. What happens is that I try to use a browser
(used both Mozilla and Konqueror) and I can access sites via IP addresses,
but not by using FQDN's. My Winboxes have no such trouble. If I hook the
RH9 box directly to the DSL, no problems. I verified all of the network
settings as correct. Any advice?

Add the nameservers from the command ipconfig/all in a dos prompt
to /etc/resolv.conf Example:
search fsr.net
nameserver 204.127.202.4
nameserver 204.127.202.42

is your router spitting out the correct DNS info? Is this router doing NAT?

The next place I would look is the firewall settings. On the RH9 box,
disable the firewall:

[root]# service iptables stop

and then fire up your web browser (Mozilla or Konqueror) and see if you
can browse the web. If you can browse the web with the firewall turned
off, then you need to fix your firewall settings.

FWIW, here's how to turn the firewall back on,

[root]# service iptables start

and how to save the current firewall configuration:

[root]# service iptables save

No sale - same result.

I (my newbie shirt is on) wonder if/how the packets are different that my
router would fail to resolve those http requests while my winboxes can pass
right through....

Thanx!

I used the my traceroute gui and got 3 hops using ip#, nothing with FQDN.

In article <benr81$rl2$ XXXX@XXXXX.COM >,


This seems really strange to me. Let me recap what I think you've told
us.

- Web browsers on your windows machines work just fine
- Web browsers on your RH box work fine if you use IP addresses, but
don't work if you use hostnames
- The "host" command works fine on your RH machine, so you likely have
a working nameserver configured.

[With a firewall in place, I wouldn't expect traceroute to work.]

I can think of a couple more things you can try.

- Install a command line ftp client, and see if
ftp ftp.kernel.org
connects. (Replace ftp.kernel.org with the address of your favorite FTP
server. If this works, try looking ftp://ftp.kernel.org with a Linux
web browser. Try it with a different browser if you have one (e.g.
Konqueror).

- Install wget, and try
wget www.kernel.org
(do this in /tmp or somewhere equally innocuous.)

Dell had an updated firmware set dated 6 Feb 2003 - uploaded it and tried
again, same result. This is really a stinker...you'd think it would have
been included in their support documentation on their website - someone else
would have faced this issue, seemingly.

[pause]

I searched Dell's support, and today there were several hits on linux and
router topics, but wouldn't you know it, the forums server is down
(figures...)

I will wait and see what these report - bet it's now a "known issue"

Catch you later

t appears, from looking at the support forums at dell, and the Truemobile
1184 information, that the device set is configured to only accept traffic
from winboxes (ironic, since a form of linux is the OS for the router).

I was an idjit for buying the product - the business I'm starting may have
expanded to include mac and linux boxes based on the needs of my customers,
and had I read more carefully, I would have spent my money elsewhere.

I suckered myself for the sake of convenience, but now, since I am past the
purchase period return point, I am not sure what I can do about it. I do
think that even though Dell makes good computers, I'd watch it on the
peripherals, and DO NOT buy the Dell-branded wireless router products if you
want to have a mixed network (of course, if they were willing to fix it, I
might not be so harsh). I am sending this opinion to the Dell newsgroup,
and I have an additional note for them: Why do you have to be so propietary
with your peripherals? Don't you folks understand that if you make the best
hardware that will take care of our needs, even if our needs include
non-dell products, we will take care of you? Y'all soured me a bit on this
issue.

Lenard, Jim and Allan, thank you for trying to help me resolve the issue,
you guys were very helpful.

Regards, MG
