Suddenly failed to connect
Dear Ubuntu Users My wife and I share a four port router and we both are running 10.04 My Internet connection is fine but she is now receiving 'unable to connect to server' There is no hardware fault as the machine is dual boot and MSwindows connects OK I have checked /etc/resolv.conf and that is fine. Ran pppoeconf but could not make any sense of the output ( it opened a ncurses window, did some scanning and reported on both machines aid on both machines that it could not connect - obviously wrong on mine). Then ran ifconfig -a on both machines the results are as below: *** Machine NOT connecting: sim...@simone-computer:~$ ifconfig -a eth0 Link encap:Ethernet HWaddr 00:0f:ea:de:1c:47 inet6 addr: fe80::20f:eaff:fede:1c47/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:33 errors:0 dropped:0 overruns:0 frame:0 TX packets:12 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:1980 (1.9 KB) TX bytes:636 (636.0 B) Interrupt:19 Base address:0xd800 --- not in my file as below loLink encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:318 errors:0 dropped:0 overruns:0 frame:0 TX packets:318 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:58073 (58.0 KB) TX bytes:58073 (58.0 KB) sim...@simone-computer:~$ Machine connecting OK: da...@djb-p4:~$ ifconfig -a eth0 Link encap:Ethernet HWaddr 00:20:ed:5f:47:56 inet addr:192.168.1.33 Bcast:192.168.1.255 Mask:255.255.255.0 inet6 addr: fe80::220:edff:fe5f:4756/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:14339 errors:0 dropped:0 overruns:0 frame:0 TX packets:13881 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:11667495 (11.6 MB) TX bytes:1505608 (1.5 MB) loLink encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:280 errors:0 dropped:0 overruns:0 frame:0 TX packets:280 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:24602 (24.6 KB) TX bytes:24602 (24.6 KB) vboxnet0 Link encap:Ethernet HWaddr 0a:00:27:00:00:00 not in file above, what is this ? inet6 addr: fe80::800:27ff:fe00:0/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:18 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:804 (804.0 B) da...@djb-p4:~$ ifconfig -a *** I have been struggling with this for some time but no joy.

Re: Suddenly failed to connect
Hi David, Looking at the ifconfig output there, it appears your wife isn't getting an IP address assigned to her computer, first i would check her connection settings, to do this head to the upper right corner of the desktop and you will see all those icons in the panel, hover your mouse over each one until you get a tooltip that says something like 'Wired connection 'eth0' active'. Right click on that icon and select Edit Connections, then select eth0 (or whichever one she normally connects with) and hit the edit button. Then just go through and make sure she has the same setting's as you do. Specifically make sure she is using DHCP automatically. Sorry if the above doesn't make complete sense, i try to be as clear as possible. Let us know how it goes.

Re: Suddenly failed to connect
Thanks very much Ryan, that has fixed it. My wife has Parkinson's so she must have accidentally hit this icon when shutting down - it is very close to the shut-down etc icon. Funny enough this particular icon is not present on my machine on the toolbar top right hand side. The same connection editing screen can be reached by SystemPreferencesNetwork Connections. Thanks very much again, I have learnt something.
