This got resolved as I had broken network profiles which replaced working configuration files with non-working ones. Anyway, after some testing and scratching I got this setup working somewhat reliably on etch: - gprs ppp options and chat scripts are working with pon and poff - ppp0 is setup to call provider gprs in /etc/network/interfaces - eth0 setup with DHCP in /etc/network/interfaces with post-down calling 'ifup ppp0' when cable gets disconnected and pre-up calling 'ifdown ppp0' when cable is connected - ppp0 and eth0 are not marked auto, instead ufplugd checks for the cable at boot time and later on - a custom udev rule is setup to call 'ifup ppp0' when the Vodafone GPRS modem is plugged in, it disconnects automatically -- the rule is based on http://www.clasohm.com/blog/one-entry?entry_id=56856 - gnome is setup to show two network-admin applets for the user, one for ppp0 and one for eth0 interface, they show the state of the interface somewhat reliably and also show which one is actively transmissing data So to recap, udev is handling the plug-in GPRS modem and ifplugd handles the ethernet cable, resolvconf manages name server changes. /e/n/interface tricks enable GPRS when ethernet cable inserted or removed (or re-enable if lan cable is removed while modem was already in, which takes care of the default route problem when multiple connections are active). Only few problems remain: - GPRS modem can be unresponsive while udev rule is doing 'ifup ppp0' which shows as it replies with 0.0.0.0 IP address and phony DNS server name, user can only re-insert the device and hope for the best, adding delays prior to ifup does not seem to help - ifplugd seems a lot slower than network-manager so network changes take a few tens of seconds, or more if the modem was just inserted I hope this helps someone. -Mikko -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
