web browsing - some sites blocked some not


Hi all...
I'm new to linux and to this forum.

I installed SuSE linux 10.1 on my PC and got to problems:

1) when I open FireFox, I can't see google. I can go on Novell's site, but, most sites seem blocked (unavilable). what can I do to have a normal access to all sites (it's so bad, I have to use the XP to post this).

I have an external ADSL LAN modem/router, but I don't think it's a problem with him couse when I star MS-XP
I dont have any restriction.

2) I have two HD's. on hda I have XP/sp2 and on hdb have the linux. I cant access the XP (NTFS) drivers from linux. int the initial startup I can catch a glimps that the mounting process fails beacouse "dev/hda1 not exist" or something like that.

thanks a lot,
Gal

i think we need to define what "blocked" means a bit more... can you get these sites via curl or another much simpler client? you don't mention anything about proxies or such, so what happens if you run "curl -v www.google.com"?

can you ping any sites?
Does it work if you shutdown the SuSe Firewall for a moment in order to see if this is where you've to adjust something?
Do you have got a DHCP on your router?
Has /etc/resolve.conf a nameserver entry listed?

2nd. I need an output of
Code:
fdisk -l
here so
I can try to tell you how to setup your /etc/fstab to read files from NTFS.

nothing yet... got this from curl

hi all,

as far as the mount, everything is fine, thanx...

I tried curl and got this:

linux-zsnc:~ # curl -v www.google.com
* getaddrinfo(3) failed for www.google.com:80
* Couldn't resolve host 'www.google.com'
* Closing connection #0
curl: (6) Couldn't resolve host 'www.google.com'

1)you guy said "disable Firewall" and "ping", how do I do it?

2) DHCP? the router has DHCP, how do I sync between the linux and the router?

2) firefox plug-ins install? dont know if there are. how do I check and install?

guy's, let's face it, in most cases, the SuSE archive is really BAD.

thanks

you dont need to disable ping. you got that part wrong.
check to see if you have firewall rules set, in the terminal type iptables -L -v
can you access other sites than the novell site?
plugins should be a later concern for this.

you dont seem to be able to resolve google.com which must be a dns problem. trying using different dns servers in /etc/resolv.conf

cat /etc/resolv.conf

are your dns servers listed there? If your behind a linksys router, use your router as the dns server.

As for firewall you can at bash
yast2 firewall then turn it off.

Try doing IPTABLES -F then dig www.google.com

If that doesnt work, try doing rcnetwork restart after the iptables.

tried your stuff... nothing yet, here is some information

basic things I checked:
a)the internet provider gives an IP and the DNS (new every time).
b)in the router (aztech 600E) the firewall is off, and DHCP is set to automaticly get whatever it needs.
c) i notice that sometime it will go into the novel website and sometimes not. I even got to this site once, as I tried moving in the site it gave me the "Unable" massage again and didn't go back. reopening the browser didn't help... it just got worst.

here we go, the iptables output(a lot):

right, we've already seen that it's dns... not firewalls or anything from what we can see... we saw you can't curl google.. can you ping it? dig it? resolv.conf clearly has no dns servers listed there...

on win,do a ipconfig /all and copy the dns servers and paste them to /etc/resolv.conf. everything should work fine after that.

Thumbs down noop

well... from ipconfig I got :

Physical Address. . . . . . . . . : 00-0C-6E-73-04-22
Dhcp Enabled. . . . . . . . . . . : Yes
Autoconfiguration Enabled . . . . : Yes
IP Address. . . . . . . . . . . . : 10.0.0.1
Subnet Mask . . . . . . . . . . . : 255.0.0.0
Default Gateway . . . . . . . . . : 10.0.0.138
DHCP Server . . . . . . . . . . . : 10.0.0.138
DNS Servers . . . . . . . . . . . : 10.0.0.138

and I changed the DNS on linux.
now, when I check the network information (via the icon on the right side, down) i get the same numbers accepts there is also a Broadcast Address 10.255.255.255... don't know what that address is for.

I did curl and got this:

linux-zsnc:~ # curl -v www.novel.com
* About to connect() to www.novel.com port 80
* Trying 1.0.0.0... No route to host
* couldn't connect to host
* Closing connection #0
curl: (7) couldn't connect to host

can we fix that "No route..."?

thanx.

you appear to have fundamentally changed your network settings. all you need do is add name servers to resolv.conf, nothing more nothing less.

Thumbs down ehh. got a nameserver line, still nothing

well,

in the /etc/resolv.conf file there is 1 line:

nameserver 10.0.0.138

(same as DNS)

still get the same answer from curl.

thanx
