Looks like the typical problem coming from a DHCP setup :-) (...) > I seem to have NetworkManager active (I think I blindly opted for it > during the upgrade process - not sure) <# ps -efl | grep -i network> > 5 S root 1832 1 0 80 0 - 19611 - 05:23 ? \ > 00:00:00 /usr/sbin/NetworkManager > </# ps -efl | grep -i network> > > ( > Do I really need it?

But deciding what to do with NM is a decision that has to be taken by the user. Some of us keep NM installed but have it disabled while others prefer to directly remove the package. OTOH, other people seems to be happy with NM and use it every day :-) > <$ cat /etc/network/interfaces> > # The loopback network interface > auto lo > iface lo inet loopback > > # The primary network interface > allow-hotplug eth0 > #NetworkManager#iface eth0 inet dhcp > </$ cat /etc/network/interfaces> So your network card settings (IP, netmask, gateway, DNS...) all comes from your router, right? > ( > Old interfaces file was identical, except that the last line wasn't > commented-out, i.e.: 'iface eth0 inet dhcp' I tried it without much > success. > ) You need to configure your "/etc/network/interfaces" file to use a setup that suits your needs: http://wiki.debian.org/NetworkConfiguration (...) > <# ifconfig -a> > eth0 Link encap:Ethernet HWaddr 00:26:18:72:71:14 > inet6 addr: fe80::226:18ff:fe72:7114/64 Scope:Link UP > BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX > packets:4317 errors:0 dropped:0 overruns:0 frame:0 TX > packets:3643 errors:0 dropped:0 overruns:0 carrier:0 > collisions:0 txqueuelen:1000 > RX bytes:4309480 (4.1 MiB) TX bytes:490343 (478.8 KiB) > Interrupt:20 Base address:0xe000 The above means that your network card has been recognized by the system but it has no data on it (no IP, netmask...) so it's normal that you cannot browse the network. Either your "interfaces" file is wrong or your router cannot reach your computer or has any problem to provide all the required parameters to your machine. I would start by "/etc/network/interfaces", yo can try: *** # The loopback network interface auto lo iface lo inet loopback # The primary network interface auto eth0 iface eth0 inet dhcp *** Save the file and then issue "ifdown eth0" and "ifup eth0" to reload the interface. After that, run "/sbin/ifconfig" and "ip ro" to check all is okay... and if it's not, run "dmesg | grep eth0" to find out why :-) Greetings, -- Camaleón -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
