I recently installed RedHat 5.1. I have a Cirrus Logic 33.6 PNP modem. With X-Windows, I set up a PPP connection to my ISP, it dials up the number, waits a few minutes, then my modem clicks like it disconnected and I can't get a connection. Does anyone know why this is? My friend said it's not my modem because if it was, I wouldn't be able to dial up.

Put
      DEBUG=yes
in /etc/sysconfig/network-scripts/ifcfg-ppp0.
Attempt to dial up again.  Then look in /var/log/messages.

PS: It's "X" or "The X Window System", but not "X Windows".  See "man X" for more information.

First of all either if you use x-windows or command prompt only do the following:
First of all make sure you have installed ppp support...then

1) go to /etc/ppp and edit the "options" file there (vi options), here you must add the following lines:
modem /dev/cua1 (cua1 stands for com2 and cua0 for com1)
defaultroute
crtcts
2) now edit the file /etc/resolv.conf to point to the correct nameservers,
for instance
domain ns1.otenet.gr
nameserver ip.address.of.n1.otenet.gr
3) launch "minicom" (did you know that ezppp is also available for Linux, it simulates windows95 dial-up networking and works great for x-windows only)
4)call your isp and hook up to him
5) press ctrl+q
6)answer yes to the question "exit without reseting"
7)run as root:
root#] pppd
8)to make sure do a ifconfig -i and see if there is a device called ppp0
if there is you are ready.
If you are connected and you cant resolve the names of hosts then the problem will be spotted in /etc/resolv.conf file, it means your nameserver entry isn't correct.
