127.0.0.1 -> a web page
by Montana Quiring 27 Feb '07

27 Feb '07

I am playing around with the idea of putting a hosts file on the the computers I look after that points a lot of sites to 127.0.0.1 (i.e. http://www.mvps.org/winhelp2002/hosts.htm ) I've been testing it on my computer and it seems to work well, except it would be nice if it would display a custom page (stored locally), instead of the default "Unable to connect"(FF), or "The page cannot be displayed" (IE). I know there are som shell script type web servers for linux but this would need to be a … [View More]

Shaw Internet stops working for an hour or so
by Bill Reid 21 Feb '07

21 Feb '07

I am seeing a problem with Shaw Business Internet that has me puzzled. I have a Linux server connected to the Shaw DOCSIS cable modem. It has been running without problems until Shaw did some "network upgrades" on Jan 11. Since then the Internet goes away for 1-2 hours every day or so. Initially I thought it was Shaw's problem and they sent techs out twice. They adjusted the signal levels but the problem still persisted. Power cycling the modem does not get the interface working. Doing a … [View More]

Thanks so much Colin! Exactly what I needed - PhotoRec is gleaning files off the memory card right now ... There have been times in the past when I could have used TestDisk to fix my corrupted Partition Tables. Downloaded it as well.

[Fwd: ISC Bulletin #1]
by John Lange 16 Feb '07

16 Feb '07

Some on this list may find the following information interesting. Note that the root name servers are protected by "anycast" and they are crediting that with resisting the attack.

You do need a userid/password to access the router. By sharing your Internet you have access to the 1,000s of routers arouind the world I ordered my yesterday. Not sure if the supply has run out. -- Bill
