Cannot surf internet (wvdial)
 

Hi,

I'm using RedHat 8.0, kernel 2.4.20-20.8. I've installed this rpm "ltmodem-kv_2.4.20_20.8-8.26a9-1.i386.rpm" for my Lucent win modem. After the installation, I followed the guide for it in /usr/share/doc/lt.../DOCS and ran wvdialconfig. Everything seemed to be running well and I could dial-up to my ISP with wvdial and it started pppd automatically. But, after opening Mozilla/lynx and try some url, it said cannot connect or no connection. I've tried rebooting many times and I've made sure that I missed nothing from wvdial guide. But still I can't connect to internet with my linux (and have to boot to windows for sure!). How do we know that Mozilla/lynx use correct connection, or is there anything that I need to change in /etc/xxx.conf?

"try some url, it said cannot connect or no connection."

You need to configure /etc/resolv.conf

Call your ISP and ask him what his Domain Name Server is. Ask him for the DNS in both letters and numbers. Then put two lines in /etc/resolv.conf following this example

search jimdandyisp.com
nameserver 204.110.56.8

Thanks a lot! It works now. I don't have to boot to Windowzzz anymore to surf!

Hi,

Sorry. How do I enable other users (other than root) to use wvdial. I tried using wvdial with my normal user account and it said:

--> WvDial: Internet dialer version 1.53
--> Cannot open /dev/modem: Device or resource busy

I tried chown wvdial and /dev/modem to root:internet_group with my user name in internet_group, but still the same error occured. Does it has something to do with normal user cannot insmod and modprobe lt_modem.o and lt_serial.o modules? But I think the modules are already loaded when I boot up.

"How do I enable other users (other than root) to use wvdial. "

You have to set the permissions of both /dev/modem and the device that /dev/modem links to to 777.
