Do you have the nameservers in your /etc/resolv.conf file? Mine for a sample:
Code:
domain infoave.net
nameserver 206.74.254.2
nameserver 204.116.57.2
Is that a serial port modem or USB (some winmodems in that situation)?

Serial ports:
Com1 in Windows = /dev/ttyS0 in most distros of Linux
Com2 in Windows = /dev/ttyS1 in most distros of Linux

If so, make a link as root:

ln -sf <device where you have the serial port modem connected> /dev/modem

I have a win<something> or some other kernel module driver I have to install.
# Compiling/installing kernel modules
You will need to have installed:
1. The developmental packages (compiler)
2. The kernel-source code that matches your running kernel
3. The module source or install code

Check out your system and look under the hood and see if you installed the stuff you need to do the job. Open an x terminal and type in this sequence of commands to see what kernel we are running and see if you have the kernel source installed:
Code:
[fancy@tinwhistle fancy]$ su -
Password:
[root@tinwhistle root]# uname -r
2.4.20-28.7
I am running kernel version 2.4.20-28.7. Do I have the proper source code?
Code:
[root@tinwhistle root]# cd /usr/src
[root@tinwhistle src]# ls -alc
total 3
drwxr-xr-x    4 root     root          136 Jun 12 14:53 .
drwxr-xr-x   16 root     root          424 Jun  4 12:04 ..
lrwxrwxrwx    1 root     root           14 Jun  4 12:11 linux-2.4 -> linux-2.4.20-28.7
drwxr-xr-x   16 root     root          584 Jun  4 12:11 linux-2.4.20-28.7
drwxr-xr-x    7 root     root          168 Jun  4 12:08 redhat
[root@tinwhistle src]#
I do have the same kernel version source code installed in the directory /usr/src/linux-2.4.20-28.7 and there is a symbolic link named linux-2.4 pointing to it.

If you don't see something similiar to this (but in color), you will need to install the kernel source.

NOTE: I noticed that Red Hat didn't make the symbolic link /usr/src/linux that all of the INSTALL files that I have read mentioned that I need. I may as well make one now to save editing the files in the source code every time I need to compile anything concerning the kernel. So, I'll make that link just now:
Code:
[root@tinwhistle src]# ln -s linux-2.4.20-28.7 linux         
[root@tinwhistle src]# ls -alc
total 3
drwxr-xr-x    4 root     root          160 Jun 12 15:46 .
drwxr-xr-x   16 root     root          424 Jun  4 12:04 ..
lrwxrwxrwx    1 root     root           14 Jun 12 15:46 linux -> linux-2.4.20-28.7
lrwxrwxrwx    1 root     root           14 Jun  4 12:11 linux-2.4 -> linux-2.4.20-28.7
drwxr-xr-x   16 root     root          584 Jun  4 12:11 linux-2.4.20-28.7
drwxr-xr-x    7 root     root          168 Jun  4 12:08 redhat
[root@tinwhistle src]#
Ah, there it is, so that's done.

Next, did I install the compiler?
Code:
[root@tinwhistle src]# gcc -v          
Reading specs from /usr/lib/gcc-lib/i386-redhat-linux/2.96/specs
gcc version 2.96 20000731 (Red Hat Linux 7.3 2.96-113)
[root@tinwhistle src]#
Yes, I have a compiler installed.

If you don't have those two things installed, you have to install them first off your install CD.

If they are installed, download the source and happy compiling. Make sure you carefully read the README and INSTALL files after extracting and before compiling/installing.

Is the Troubleshooting ISP Connection Problems link I previously posted of no help?

What are the results of these commands?:

ping <IP of ISP>
ping <name of ISP>
ping yahoo.com
traceroute yahoo.com

Is your /etc/resolv.conf file correct for your ISP?

In RedHat, the file you tail to watch for the error messages in the troubleshooting link is /var/log/messages.

Also, either use /dev/ttySL0 as the modem, or, as root,:

ln -sf /dev/ttySL0 /dev/modem

ok..
i've check the resolv.conf..and it's blank.nothing inside it...

i use wvdial n below is the example result:

[root@Cygnus root]# wvdial TMNET
--> WvDial: Internet dialer version 1.53
--> Initializing modem.
--> Sending: ATZ
ATZ
OK
--> Modem initialized.
--> Sending: ATDT1515
--> Waiting for carrier.
ATDT1515
NO CARRIER
--> No Carrier! Trying again.
--> Sending: ATDT1515
--> Waiting for carrier.
ATDT1515
Caught signal #2! Attempting to exit gracefully...
--> Disconnecting at Sat Apr 23 15:57:19 2005
[root@Cygnus root]#


this is my wvdial.conf file:

[Modem0]
Modem = /dev/ttySL0
Baud = 115200
SetVolume = 2
Dial Command = ATDT
Init1 = ATZ
FlowControl = NOFLOW
[Dialer TMNET]
Username = xxxxxxxx
Password = xxxxxxxx
Phone = 1515
Stupid Mode = 1
Inherits = Modem0


i try to dial my h/p number (change the 1515 to my h/p number) and it's working.that's mean my modem is properly setup.the problem is the configuration to the ISP.

Place your ISP nameserver numbers in your /etc/resolv.conf file and try again.

Make sure you read through the README and INSTALL files in the driver tarball after you extract the driver to install. You must have missed something on your first read.

Will your modem work in Linux?
The kppp Handbook
Dial-up Networking Configuration Using KDE's Kppp

Personally, because of the winmodem headaches I had, I tossed my winmodem piece of junk into the trash and went for an external serial port modem.

For a little money, it saves a lot of headaches because they will work with all computers. These have the real hardwardware that don't need propriatory drivers in order to make the CPU pretend to be a modem and they will work with all operating systems with little configuration.

Keep an eye on these places. I picked my modem up for around $14. Remember, you want a serial port modem for the easiest, fastest and best dial up modems. As you have discovered, USB can also have winmodems (no modem hardware, the CPU has to emulate it) and be practically useless unless you run a Windows version that will support it.

I'm out of ideas.

Are external serial port modems very expensive there? That is really the best modem you can get and it will work with all operating systems.
