Sometimes the key that is generated on Windows machines is malformed as far as openssh is concerned. Make sure your authorized_keys entry looks like this ssh-rsa AAAAB3Nz(snip)KZbC1PEWyI4Q4esMJogfsWpXnB8Q== CommentAboutTheKey I've used putty with it's key store 'pageant' with quite some success. It's a background application that does the key auth for you. You decrypt your key once (your private key is _should_ be encrypted.... ) and it happily does nothing most the time. I think putty prompts you for your key, but I seem to remember it having mixed success. Hope that sheds some light on the situation. rob On Sun, May 2, 2010 at 10:24 PM, Kelly Leveille wrote: > Rob, > > Is the Ubuntu server "rejecting your key" during the SSH login session?

Detillieux) Date: Tue, 4 May 2010 12:24:59 -0500 (CDT) Subject: [RndTbl] MUUG Meeting, May 11, 7:30pm -- Podcasting Message-ID: <201005041724.o44HOxJ14493@iron.cs.umanitoba.ca> The Manitoba UNIX User Group (MUUG) will be holding its next monthly meeting on Tuesday, May 11. The meeting topic for this month is as follows: Podcasting Podcasting lets you share your thoughts with the world through an audio subscription model. How would you plan and organize a podcast of your own? What tools should you use to record, edit and encode your podcast? What distribution tools are used? How much does it cost to podcast? Can you use free or open source software for podcasting? MUUG member Brian Doob has been podcasting for three years and will answer these and many other questions. The group holds its general meetings at 7:30pm on the second Tuesday of every month from September to June. (There are no meetings in July and August.) Meetings are open to the general public; you don't have to be a MUUG member to attend. ********************************************************************** Please note our meeting location: The IBM offices, at 400 Ellice Ave. (between Edmonton and Kennedy). When you arrive, you will have to sign in at the reception desk, and then wait for someone to take you (in groups) to the meeting room. Please try to arrive by about 7:15pm, so the meeting can start promptly at 7:30pm. Don't be late, or you may not get in. (But don't come too early either, since security may not be there to let you in before 7:15 or so.) Non-members may be required to show photo ID at the security desk. Limited parking is available for free on the street, either on Ellice Ave. or on some of the intersecting streets. Indoor parking is also available nearby, at Portage Place, for $5.00 for the evening. Bicycle parking is available in a bike rack under video surveillance located behind the building on Webb Place. ********************************************************************** For more information about MUUG, and its monthly meetings, check out their Web server: http://www.muug.mb.ca/ Help us promote this month's meeting, by putting this poster up on your workplace bulletin board or other suitable public message board: http://www.muug.mb.ca/meetings/MUUGmeeting.pdf -- Gilbert E.

And that PSU would likely last a lot longer than the SFF version in a shuttle. (Usually quieter, too.

I am trying to setup an webserver using Ubuntu 9.10 Server, Karmic Koala. I have it setup in my home office behind a D-Link router. I installed DNS server, LAMP, email server, and Tomcat. To get familiar with configuring DNS, I attempted to simply setup a DNS as both a caching server and create a master entry to point to a website on itself. I called the website "example.ca". The D-Link router acts as a firewall so it shouldn't propagate. But it isn't working, when I use "nslookup example.ca" the response is "*** Can't find example.ca: No answer". When I try "ping example.ca" the response is "unknown host example.ca". What did I do wrong? I changed "/etc/resolv.conf" to have the IP address of my server instead of the router or my ISP, although the domain and search are still my ISP. I ensured the "forwarders" address in "named.conf.options" is my router. I did restart the DNS service after each change. Bit it still isn't working; I can lookup any address from the internet but my own server does not resolve. I followed these instructions: https://help.ubuntu.com/10.04/serverguide/C/dns-configuration.html http://ulyssesonline.com/2007/11/07/how-to-setup-a-dns-server-in-ubuntu/ Thanks, Rob Dyck From sean at ertw.com Mon May 31 18:35:01 2010 From: sean at ertw.com (Sean Walberg) Date: Mon, 31 May 2010 18:35:01 -0500 Subject: [RndTbl] DNS Ubuntu In-Reply-To: <000201cb0113$83e4afc0$6400a8c0@wp.shawcable.net> References: <4BF6E055.5020406@cs.umanitoba.ca> <000201cb0113$83e4afc0$6400a8c0@wp.shawcable.net> Message-ID: Did you create a zone entry in named.conf and the associated zone file? zone "example.ca" { type master; file "example.ca.db"; }; example.ca.db: IN A 192.168.1.1 When you restart named, always look in the logs (/var/log/messages on most systems) to see if any zones got turfed. If you make a mistake, named will not load the zone, but will happily continue on with the next zone. Does your forwarder work? eg can you nslookup cisco.com @localhost ? Is named bound to all the interfaces? BTW, if you're just trying to get example.ca working for development, the fastest way is to edit your hosts file(s) and skip DNS entirely. DNS takes a few "oops" moments to understand, and is often best skipped if possible.

Beware that unless your ports are explicitly eSATA, they likely won't handle hot plugging properly. (i.e. You can connect your onboard SATA ports to eSATA adapter brackets - and this will generally work - but they don't magically support all the "e" aspects unless designed to do so; some are, some aren't.) Also if you want to use any kind of multi-bay enclosure, the host ports must explicitly support SATA Multipliers (multiplexers?) or you won't be able to access any of the drives in that enclosure reliably. -Adam -----Original Message----- From: Dan Martin Date: Mon, 31 May 2010 21:15:09 To: MUUG roundtable Subject: [RndTbl] eSATA I am considering adding eSATA and external toasters to my Mac Pro, in order to maximize swapability but maintain speed.
