Let's think disaster *prevention* 2 servers 2 server rooms in 2 buildings some distance apart a very fast piece of string between the two multiple redundant routes to each server room synchronise data 'live' between the two sets of servers ideally, the servers form cluster pairs Then if someone nukes server room 1, drives a JCB though a cable, the servers in room 2 take the load automatically. hopefully. ideally. something to work towards... ... and I'd have tape backup just in case. tapes offsite. Backup servers are overkill if you can afford for the whole network to be down for a week without complaint. Quantify the cost. Even schools now rely 100% on computer availability, and at some point the worst will happen. Usually a week before the Bursar has to present accounts to his superior, or a week before the Easter coursework deadline. Naive question: can you 'cluster' Linux servers in this way, coz what I have been describing is feasible under Win 2000 server enterprise?

bombproof or overkill recovery plan
by Matt Johnson 11 Jul '03

11 Jul '03

If I was starting from scratch... As a method of complete disaster recovery, would it be overkill to buy two identical (cheapish) servers. Server 1 would have two identical 40gb ide disks. I plan to 'dd' from one disk to another each night. Then I'd have a complete image nightly of our server, right? If things went horribly wrong, I could replace server 2's hard drive with either of the two in server 1 and it would work as the hardware in both servers is the same? Is two servers, and two hard drives in server 1, overkill? Or in a school with 600 pupils and staff relying on these systems, is this redundancy sensible, if not necessary? (I'd probably use server 2 to do a copy of any key files and home directories from server 1 as well - they'd be in different areas of the building. This would be for a teacher accidently deleting all their work, or the like). Silly question... Can you 'dd' from the drive your using at the time? ie. If I've booted from, and am using hda, can I use it as my 'dd' input? Thanks for any pointers. -- Matt ________________________________________________________________________ Want to chat instantly with your online friends? Get the FREE Yahoo!

FW: [ooo-announce] OpenGroupware.org: SKYRiX OPEN SOURCES ITS GRO UPWARE SERVER
by Chris Puttick 10 Jul '03

10 Jul '03

That should do it... A cutdown version of SKYRiX is what powered the groupware part of SuSE Linux Email Server 3.x - tad buggy yes, but a little open source reviewing and this should be a very, very neat solution... >-- Original Message -- >Reply-To: announce(a)openoffice.org >Date: Thu, 10 Jul 2003 19:17:12 +0800 >To: announce(a)openoffice.org >From: Jacqueline McNally <jacqueline> >Subject: [ooo-announce] OpenGroupware.org: SKYRiX OPEN SOURCES ITS GROUPWARE >SERVER > > >MEDIA RELEASE FOR IMMEDIATE RELEASE NEW PROJECT FORMED: OpenGroupware.org, AS SKYRiX OPEN SOURCES ITS GROUPWARE SERVER July 10, 2003 - OpenGroupware.org ('OGo') project announces its formation and the release today to the worldwide open sou >ce development community of its groupware server software. The software provides the server components necessary for full office collaboration with the OpenOffice.org suite and various other Linux and Windows groupware clients. OGo software runs >n Linux and Solaris (www.OpenGroupware.org) The OGo project is a fully independent open-source project, but will inter-operate with the OpenOffice.org software and other similarly open clients via open standards. The OGo software is based i >itially on the contribution of the code of SKYRiX 4.1 Groupware Server, a mature product that has been in development for 7 years, and one of the earliest groupware products for the Linux operating system. The contributor, SKYRIX Software AG, is >ell known in Germany as a leader in Linux groupware (www.SKYRiX.com). "We are extremely excited to form OpenGroupware.org and to collaborate with OpenOffice.org to serve the open source community worldwide," said Jens Enders, president and CEO >of SKYRIX Software AG. "By configuring the OpenGroupware.org server together [after install] with the OpenOffice.org office suite and other leading groupware clients, our customers will be able to implement a comprehensive and integrated collabor >tion environment wholly composed of free software." The OGo software provides document sharing capabilities for OpenOffice.org documents and will enable users of MS Outlook (97/2000/XP), Ximian Evolution, Mozilla Calendar, OOo Glow (OpenOffice >org Groupware Project's client product), Apple's iCal and other standards-based groupware clients to collaborate. OGo software will enable users to share calendar, address book and e-mail information; they can communicate via instant messaging > share folders, exchange documents, track changes, share a whiteboard, and browse the Web all at the same time -- all upon open Internet standards and without paying or managing cumbersome licensing fees. Says Gary Frederick, Leader of the Ope >Office.org Groupware Project: "Just to be perfectly clear, this is an MS Exchange replacement. OGo is important because it's the missing link in the open source software stack. It's the end of a decade-long effort to 'map' all the key infrastruct >re and standard desktop applications to free software. OGo offers users a free solution for collaboration and document management that, despite being free of charge, will far surpass the quality and level of collaboration found on Windows (thro >gh integration of MS Office, Exchange Server and SharePoint). Today marks the completion of 'OpenStack'." Adds Stu Green, Managing Director of Open Source Professional Services, "The release of OGo means the OpenOffice.org suite is ready for the > enterprise complete with full-featured and mature groupware solutions. These capabilities once and for all show how free software betters proprietary solutions that require licensing payments on both the client and server sides. Also, OGo provi >es multiple file format filters for creating, storing and sharing data in an open and flexible fashion. It's possible now to completely avoid proprietary file formats and non-standard XML throughout the desktop stack and infrastructure. Licensing >fees and license management are gone. And with OOo + OGo, no remote activation is required." (www.OSPSnet.com) OGo has extensive and broad support for XML based APIs:an XML-RPC 'Webservice' API, support for SunONE XML based WCAP, support for >HTTPMail/MS Exchange-based WebDAV, and finally for iCalendar files in XML notation (according to the xCal drafts). Given the XML based storage format of OpenOffice.org the OGo document storage will be able to perform feature rich team based colla >oration and content management. OGo uses a WebDAV-accessible relational database management system to make document storage accessible from the OpenOffice.org office suite. OGo is licensed under the open source dual licenses, Lesser General Publ >c License (LGPL) and the General Public License (GPL). Libraries and components are licensed under the terms of the LGPL and applications are licensed under the GPL. For users, this means in part that the OGo software can be used, improved and >edistributed at no cost. For developers, the licensing implications vary depending on the type of code contribution that is contemplated.

The Next Open Source in education conference
by James Spedding 10 Jul '03

10 Jul '03

For info (and sorry for any duplication), After the success of the first conference (the post-conference CDROM should be appearing on the cover of Linux User and Developer soon), we here at mPowerNet are keen to keep the momentum and so are planning the next one for the 16th or 17th October 2003 which will explore how Open Source solutions can help to: * Bridge the digital divide using low cost technology * Minimise hardware and software upgrades * Encourage social inclusion * Reduce environmental costs and impacts * Share resources: share knowledge: support learning The focus of the day will be wider with different strands specifically covering pedagogy, technical issues, case studies and managing change. We are looking for speakers, exhibitors and delegates for the conference which will be held in Birmingham. If you would like to be involved or have any input or feedback on the conference topics please let me know as soon as possible so I can finalise the date with the venue. If you know others who might also be interested drop me a line too. James Spedding

Speaking from an IT management perspective, there's no such thing as an overkill recovery plan... However, in the scenario you're looking at, mirroring the servers themselves would be the best bet, preferably with the servers in two separate locations. I'm also an advocate of splitting services among as many machines as I can budget for, to near-eliminate the possibility of never having total downtime.

Non-null IDENTD
by Dug Stokes 10 Jul '03

10 Jul '03

Is there any way to deny access to a user who does not return an Ident within the timeout period on Squid? I know how to ensure the ident request is sent, but if a user doesn't return a ident response, they still get access :( I don't really want to go down the road of using proxy auth unless it can be tied in with NTLM.
