Hi list,
I just duplicated my system onto a Thinkpad T40 like this:
- used netinst to install a base etch system,
- used a generated list of installed packages from my old (dying) machine
to
install all the same packages,
- compiled an extra kernel from Debian sources using my old kernel config
with a couple of changes for the different hardware,
- then copied over all my backed up data and some config files.
Foolproof, right? Well, nearly...the main problem is networking, which is
not my strong suit, so I'm hoping for a couple of tips.
On the old machine, NetworkManager worked beautifully; once I had commented
out all but the loopback interface from /etc/network/interfaces, it took
care of everything - with KNetworkManager, it would automatically connect
to a wired interface if plugged in, or to an open wireless network, asking
me for an appropriate key or passphrase if required.
During the netinstall and package installations, the wired ethernet connection
worked automatically with the e100 module and DHCP.
But now the installation is complete, there is a complex bundle of problems:
- with NetworkManager:
- Wired ethernet is claimed to be connected, sometimes reporting
a 169.* ip address, in which case pinging the router fails, or a 192.*
address,
in which case the router can be pinged; in both cases I cannot connect to
the internet, even using numerical addresses. NetworkManager reports:
"NetworkManager: <information> DHCP returned name servers but system
has disabled dynamic modification!"
-Wireless connection using wpa_supplicant fails, with this
output:
NetworkManager: <debug info> [1157879555.879241]

- If I re-establish my interfaces file and use ifupdown:
- Wired ethernet with DHCP fails with:
"DHCPDISCOVER on ethernet to 255.255.255.255 port 67 interval 4
send_packet: Message too long";
or with a static setup, it doesn't enable browsing.
- Wireless works, but not with wpa_supplicant. Uses DHCP and the airo
module.
AFAIKT (which is not very) this means that there are at least two problems:
DHCP has stopped working for the ethernet interface - presumably because
of some installed program - and wpa_supplicant is not working for the wireless
interface.
Any pointers as to how to begin solving these problems would be greatly
appreciated.
Thanks,
John
