List members, I have purchased Cricket Wireless service and have an A600 modem from them. I am attempting to set up a 3G wireless router with this system using Debian "Lenny" Linux on a Dell Optiplex GX-260 PC. I'm using usb_modeswitch-0.9.7 to "plip-flop" the modem out of storage mode and into modem mode, and I am using wvdial to initiate calling and set up the PPP session. I am using ipmasq to set up the firewall for forwarding from eth0 to ppp0 and dnsmasq to set up a DNS proxy and DHCP server. I run the script which does all this as the last call from the Runlevel 2 startup. So far, it's working pretty well, but I have two issues. If the call is interrupted for whatever reason during the session, I cannot get the session re-established. The modem dials out and establishes a link, but it never creates the ppp0 interface again. The software creates the PID file and then just seems to stop. It still reacts to a HUP signal, so it isn't hung up entirely, but it doesn't re-establish the networking, either. Of course, when the session is interrupted, I want to re-establish the internet connectivity automatically. Since this is a dedicated router, I could of course simply reboot the system, but that's a rather ham-handed approach, not to mention the fact it takes the PC a while to boot, so the internet service will tend to be down for at least a couple of minutes taking this approach. The second issue, which may be related, is that I am unable to take down the router configuration and re-establish the default configuration with eth0 obtaining the IP address and DNS information from a DNS server on the LAN. I can manually turn up the port and set a static IP, but I can't get it to automatically configure. Admittedly, this is only an issue for the time being, while I am setting up the system. Once it is set up and in place, there will no longer be a DHCP server or internet access on the LAN to which it is attached, but right now it is a pain having to disable the startup script and reboot in order to administrate the system from my LAN. -- To unsubscribe from this list: send the line "unsubscribe linux-net" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
