unable to connect to internet
Hi,
I have recently upgraded to FC4. I lost my internet connection ever since. Maybe it was just coincidence, that a problem was about to happen and i upgraded to FC4 ...I am able to connect from windows side of the same machine. I am using a ADSL connection with Huawei's SmartAX MT800 modem. The connection is like this: A telephone line goes to a ADSL Splitter & a telephone line from adsl side goes to modem & another line goes to the telephone. A cat5 cable from modem goes to ethernet port of computer. During boot up the line says Bringing up ppp0 [ok] but there is also a another message which says (which i don't think is usefull but i include it anyway): Bringing up eth0 [failed] Check cabel? but this is the message i used to get even during FC3. I was able to connect then. The system-config-network says ppp0 as active. But when i enter Code:
$ lynx http://www.google.co.in/ Code:
$ dmesg Code:
#ls -l /var/log/audit/ Code:
#setsebool dhcp_disable_trans=1 How do i connect to the internet. thank you, with regards ashwin |
Can you ping an IP address? For example does this work:
Code:
ping 68.142.226.37 If so, then it's probably a DNS problem, in which case you should check to see what servers you have set up in /etc/resolv.conf. |
Hi there!
ashwin_cse, do you have one or two ethernet cards in your machine? |
Hi,
I am not able to ping 68.142.226.37 . It says destination host unreachable. This the following of my /etc/resolve.conf Code:
;genereated by NetworkManager, do not edit! Quote:

Can you post the results of the commands (run as root):
Code:
ifconfig Code:
route |
HI,
This is the o/p of config Code:
eth0:Link encap:Ethernet HW addr:00:40:95:89:06:4F Code:
# route thank you, with regards, ashwin |
ifconfig shows that the ppp0 connection is established, so it's not that that's causing the problem. However, route shows that the default gateway of the machine is on the eth0 - so pretty much everything is being sent out through the eth0 interface, which explains why you can't get to anything on the internet.
The solution to this is to tell pppd to use the defaultroute option, and you can do this in three ways: [list=1][*]Specify defaultroute on the commandline to pppd[*]Add the defaultroute option to /etc/ppp/options[*]Add the defaultroute option to ~/.ppprc[/list=1] When you've done that, re-establish the ppp connection, run route again and you should see something like this: Code:
# route |
Hi,
i logged in as root and issued the following commands: Code:
#pppd defaultroute Code:
#cat /etc/ppp/option Then there wasn't a file in ~/.ppprc I think it will be usefull to know that its using pppoe interface. I am not able to ping 68.142.226.37 Any suggestions, with regards, ashwin |
Yeah, add it to /ppp/option and see if that helps.

Hi LQ,
I,ve recently installed FC6 on my Compaq Presario 1720IL, and was facing the same problems as posted above. I twaked all those said config files but to no avail. Then, i reinstalled the system, and after a few reconfigs and restarts, my pppoe is up and running. Though not very clear as to what had happened then and what went right now. Can anyone help???:confused: |
