Very much a newbie using Red Hat 9.1. I compiled the drivers for an LT winmodem, so now the wvdial dials out and reaches the ISP, but - while it appears to complete the connection - I'm not able to access any web sites, and when I ping any site from root, I get the no site found message.

I've run

#tail -f /var/log/messages

and I get the following:

Mar 8 19:49:40 localhost pppd [1516]: pppd 2.4.1 started by root, uid 0
Mar 8 19:49:40 localhost pppd [1516]: Using interface ppp0
Mar 8 19:49:40 localhost pppd [1516]: Connect: ppp0 <--> /dev/ttyLT0
Mar 8 19:49:41 localhost /etc/hotplug/net.agent: assuming ppp0 is already up
Mar 8 19:49:45 localhost modprobe: modprobe: Can't locate module ppp-compress-21

The next four lines identify the local and remote IP addresses and the primary and secondary DNS servers, as per usual.

I'm guessing that the problem has to do with the "/etc/hotplug..." line and the "Can't locate module ppp-compress-21" line (duh), since these lines would usually contain PAP authentication and PPP Compression info, but I have no idea how to remedy any of this.

It's been a long first slug at Linux with the modem driver compilation, and I feel like I'm very close to getting this thing solved and getting online on the Linux system. I'd appreciate any advice now for that final push! Thanks in advance.

I just had a similar issue with modem connecting and not being able to browse. Have a look at your resolv.conf file and see if your IP's addresses are in there and check to make sure you don't have a conflict with an ethernet card and DHCP settings.
