Salamoo Alikoo,
The internet was browsed on Mandrake Linux 10.1, The PC was turned off, on the morning the internet is off and may be browse the Google main page and search but the results couldn't be open, no other sits browsed.
I tried again then yahoo.com opened just only the main page no links work and google can't be browsed. after some times no site can be browsed, and so on.
Note:
- I use the Konquerer and firefox. (same result)
- The Linux machine can ping successfully to sites.
- I used FTP from Linux to another Linux Machine on the LAN and no problem.
- Linux machines haven't any error over the LAN.
- This was happened for all linux machine in the LAN.
- Some machines jus run after fresh installation.
- The other machines were working before.
- Some Machines contain Windows And Linux, Windows browsed the internet on the same machine Linux failed in browsing
- The LAN contains windows machines also
Please, help me
Thanks
dns
seems to me like a DNS problem, as Msameer said check the output of 'route -n' it shoulbe something like this
[rhanna@rhanna ~]$ route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 10.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0 eth0 0.0.0.0 10.0.0.2 0.0.0.0 UG 0 0 0 eth0
if the last line isn't there then you can do
route add default gw "router_ip"

Here you are
There are the output of the commands:
ifconfig -a

What about Viruses and Worms?
I can think it may be a virus or a worm.
I faced this problem before with windows, it was a worm, so why not in Linux?
OK, anyway can you send me an open source and free cost antivirus for Linux, or How can i scan online my Linux machine from virus?.
I need an Antivirus regardless my problem.
Thanks.
do not confuse linux with win
do not confuse linux with windows and jump to conclusions.
do #dig eglug.org or #resolveip eglug.org ?
[rhanna@rhanna ~]$ resolveip eglug.org IP address of eglug.org is 209.135.157.57 [rhanna@rhanna ~]$ dig eglug.org ; <<>> DiG 9.2.5 <<>> eglug.org ;; global options: printcmd ;; Got answer: ;; ->>HEADER opcode: QUERY, status: NOERROR, id: 38004 ;; flags: qr rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 2, ADDITIONAL: 2 ;; QUESTION SECTION: ;eglug.org.

if both work then it's not a DNS problem and we should consider other problems.
i don't think it's a worm or a virus, but there is clamav and aegis
antivirus programs.
by the way is there any other PCs on the same lan that can browse the internet correctly?

I don't think it is a DNS problem
I run These commands and this is what i got

Thanks
OK so it's not a DNS thing, h
OK so it's not a DNS thing, hmmmm . . .
ok i need to know if their are other PCs on the network that can access the net? do #traceroute google.com and see where it stops?
the best things in life are free --- so as myself
traceroute google.com

OK try this
today i had a similar problem so here it goes, i was able to ping, traceroute and everything but unable to do any browsing even through elinks.
so i opened ethereal and then tried to access any webpage and then i stped the sniffer and examined the packet and found out that the packets are going to 1.0.0.0 so this is starnge, the pings go to the right destination but http requests go to a strange IP so i just changed the /etc/resolve.conf to nameserver 194.79.96.9 instead of the router's IP and it worked. so check it out like i did and tell me
the best things in life are free --- so as myself
Thank you ramez
Thank you ramez, i change my router ip with 194.79.96.9 in /etc/resolve.conf and it is working now.
ramez my problem is fixed now but if you have a time please explain this error for me.
I change my router before this problem which was in Linux machine only!!!.
Why this problem happened?
Why 194.79.96.9 changed to my router ip?
What is ethereal?
How did you examine the packets?
Thank you ramez if you have a time to explain or not, anyway my internet is on now.
Thanks
well i don't know exactly why
well i don't know exactly why this happened ! but here is the xplanation
194.79.96.9 is a dns server on the internet, the router IP is not a dns server but it AFAIK caches the dns server of your ISP, so the case now is : i can ping, traceroute even resolve names but cannot browse, so i used etereal which is a packet sniffer ( when you open a webpage you are actually doing several things, first you are resolving the name into IP, then sending a request -syn- packet to which the server should aknowledge -ack- and then you aknowlede the acknowledgement of the server) so using the packet sniffer ethereal i can see all that, and i saw the syn packets going to 1.0.0.0 so this means that it does not know the real IP of the website, so this must be a DNS problem , so i just tried replacing the caching server of the router by a real dns server on the net in /etc/resolv.conf and it worked
but actually why it happened i still don't know
the best things in life are free --- so as myself
Another problem
sorry, the solution before solve one problem and get another one.
The Local server has a name "myserver", it was accessed by name before the previous problem but after the solution ( change DNS to 194.79.96.9) i can't access my server by name although i can access it by ip.
please help.
add it to /etc/hosts
one solution is to add a line in /etc/hosts that looks like this
xxx.xxx.xxx.xxx myserver
where xxx.xxx.xxx.xxx is the server IP address.

it is running
OK, it is running but it means that i will write this for every PC in my network.!!!!! :(

I did not understand that you have a big network and stuff, you need to configure and run a DNS server within your network.
