Usually when something like this happens I find that the simplest solution winds up being the right solution. I have noticed that when I shut down my Ubuntu box, the nick continues to give ok connectivity lights. This leads me to believe that the router and your Ubunut NIC continue to communicate. By shutting down the computer probably while it was churning at some background process most likely left the computer in a state of flux. <br><br>Try shutting down the computer for about 10 sec, unplugging the network cable, and restarting the machine. Then you can plug in the network cable and freshly renew your DHCP settings.<br><br>Hope that helps!<br><br>Joey Moe<br><br><b><i>talk-request@nblug.org</i></b> wrote:<blockquote class="replbq" style="border-left: 2px solid rgb(16, 16, 255); margin-left: 5px; padding-left: 5px;"> Send talk mailing list submissions to<br> talk@nblug.org<br><br>To subscribe or unsubscribe via the World Wide Web, visit<br>

My order<br>(and countless others, I'm sure) has been delayed, and won't arrive<br>for another 45-60 days. Not surprisingly, I have mixed feelings--I'm<br>glad that the program was successful, but I'm annoyed that it's going<br>to take so long to get my hands on an XO.<br><br>This Spring, I'm leading hikes at the Fairfield Osborn Preserve with<br>elementary school children, and I had thought that an XO laptop might<br>prove to be an excellent teaching tool. For example, I could lead<br>them to the creek, and then use the laptop to show
them pictures of<br>the creek before the big rains from two years ago. But hikes start in<br>about 30 days, which is 15-30 days (or 2-5 hikes) before I could<br>expect to receive my XO laptop!<br><br>I'm not terribly upset, though. I've led these hikes before, without<br>any such technological aids, so I know I don't need it. I just think<br>it would be a great way to enrich their experience.<br><br><br>I hope that they eventually revive the "Give 1, Get 1" program, as I<br>know a lot of people in this area who I think would really benefit<br>from them. Of course, I also hope they can significantly boost their<br>production capacity and avoid future delays.<br><br><br>-- <br>Lincoln Peters<br><anfrind@gmail.com><br><br><br><br>------------------------------<br><br>Message: 2<br>Date: Thu, 31 Jan 2008 08:48:40 -0800<br>From: Roger House <rhouse@sonic.net><br>Subject: [NBLUG/talk] Can't connect to the Internet<br>To: talk@nblug.org<br>Message-ID:

add the line,<br>ALL: ALL <br>to /etc/hosts.deny<br>and <br>sshd: 192.168.1.<br>to /etc/hosts.allow. <br>That will deny sshd for everyone not in 192.168.1.0/24.
