rsync with multi-direction delete.
by Montana Quiring 05 Oct '07

05 Oct '07

Hello, I've started working with rsync and I'm close to getting things the way I want it, but I need a bit of help from an expert to finish the project. I'm rsyncing from a directory on a server to a usb mass-storage device attached to a different computer. I'm running an rsync daemon on the server and I'm able to successfully synchronize the contents of a directory on the server to a directory on the usb device. What I want: when I delete a file or directory on either place it will remove it from the other. What it does now: If I delete a directory or file from the server it removes it from the USB device (ya!) but if I remove a file/directory from the USB device and perform an rsync it replaces the deleted file/directory. Here is the rsync command I'm using: rsync --delete --delete-excluded --recursive -uv quiringm@192.168.1.102:/mnt/hdd/music/podcasts/ /Volumes/MEK/Podcasts/ Thanks in advance for your help, -Montana

News readers (binary)
by Mike Pfaiffer 29 Sep '07

I've noticed there hasn't been an update to BNR2 in a number of years. Since it has troubles with its own database for headers I was wondering what people use as an alternative. Granted this is a question I asked a few years back, but BNR2 was updating regularly at that point. I liked BNR2 because it is able to handle "unstable" servers like Shaws. It also allows downloads from multiple servers if the completion rate isn't very good on some of them. It also allows the user to prioritise which servers are used first. Finally it allows the user to adjust the font size for high resolution monitors (always a good feature in any program). In the past I tried pan. Before the Shaw servers became unstable I was using it all the time. I'll admit to not using the last two versions. However the versions I did use all became "confused" when dealing with Shaw and even froze rock solid. I guess something tied up the download slots and refused to release them. What do people use now? I don't mind setting up a pseudo server (gets the headers and maybe does the actual downloading but only on request from the news reader). The pseudo server route has a lot of advantages if the program is stable and can handle Shaw. Later Mike

Cool new device ...
by Dan Keizer 27 Sep '07

looks like zipit is at it again ... the original zipit1 was an IM device with built-in wireless b/g .. hacked to have console access and sd card, backlighting etc .. seems the new version has some upgrades. For $150 . not too bad ... expect some good hacks when it appears: http://www.engadget.com/2007/09/27/zipit-reveals-z2-wireless-messenger-for-… Dan.

Shaw parent cache on squid.
by Sean Cody 27 Sep '07

27 Sep '07

The nice folks at Shaw tell me that their public proxy _should_ be able to peer but they haven't tested it. I've setup squid to use them as a parent but I have no idea how to tell if it is working or not. I've tried a few permutations of the config but I don't see anything in the access log with respect to the peering actually happening. I figured my cache_store log would tell me something but I don't have the column decoder ring quite yet. # Peer with ICP #cache_peer proxy.wp.shawcable.net parent 3128 3130 default # Peer without ICP cache_peer proxy.wp.shawcable.net parent 3128 7 no-query no-digest Any ideas? -- Sean -- Sean

NFS issues
by Trevor Cordes 27 Sep '07

27 Sep '07

I've had this problem for a long time and I've never been able to solve it. I have a simple NFS setup between 2 FC5 boxes. I've never been able to get (what I think is) locking to work. NFS works great for 99% of uses/apps, but things that appear to do locking fail in strange ways. 1. OpenOffice's oocalc will take a long time to open a file across NFS and when it finally does, it's read-only. 2. Flock calls in perl will hang indefinitely over NFS. Here's my /etc/exports on the server: /data 192.168.100.1(rw,insecure,async,no_subtree_check,no_root_squash) Here's my fstab on the client: 192.168.100.2:/data /data nfs rw,hard,intr,timeo=10,nosuid,bg,udp,rsize=8192,wsize=8192 0 0 server: #cat /etc/sysconfig/nfs STATD_PORT=32765 STATD_OUTGOING_PORT=32766 MOUNTD_PORT=32767 RQUOTAD_PORT=32764 server: #ps -ef | grep -P '\[(lock|nfs)|statd|portmap' | grep -v grep rpc 2169 1 0 2006 ? 00:00:00 portmap root 2970 7 0 2006 ? 00:00:00 [nfsd4] root 2971 1 0 2006 ? 05:40:06 [nfsd] root 2972 1 0 2006 ? 05:34:22 [nfsd] root 2973 1 0 2006 ? 05:26:16 [nfsd] root 2974 1 0 2006 ? 00:00:00 [lockd] root 2976 1 0 2006 ? 05:33:17 [nfsd] root 2977 1 0 2006 ? 05:27:06 [nfsd] root 2978 1 0 2006 ? 05:29:35 [nfsd] root 2979 1 0 2006 ? 05:25:46 [nfsd] root 2980 1 0 2006 ? 05:33:20 [nfsd] rpcuser 23364 1 0 2006 ? 00:00:00 rpc.statd -p 32765 -o 32766 client: #ps -ef | grep -P '\[(lock|nfs)|statd|portmap' | grep -v grep rpc 3077 1 0 Jun15 ? 00:00:03 portmap root 3095 1 0 Jun15 ? 00:00:00 [lockd] server iptables rules (abbreviated version!): [ "$HAVE_NFS" = 1 ] && iptables -A fragments -s $nfsallow -j RETURN iptables -A fragments -j DROP iptables -A aad_first -f -j fragments if [ "$HAVE_NFS" = 1 ]; then iptables -N nfs iptables -A nfs -p tcp --dport sunrpc -j ACCEPT iptables -A nfs -p udp --dport sunrpc -j ACCEPT iptables -A nfs -p tcp --dport nfs -j ACCEPT iptables -A nfs -p udp --dport nfs -j ACCEPT iptables -A nfs -p tcp --dport 32765:32768 -j ACCEPT iptables -A nfs -p udp --dport 32765:32768 -j ACCEPT iptables -A iint -s "$nfsallow" -j nfs iptables -A aaa_persist -s "$nfsallow" -p tcp --dport sunrpc -j RETURN iptables -A aaa_persist -s "$nfsallow" -p udp --dport sunrpc -j RETURN iptables -A aaa_persist -s "$nfsallow" -p tcp --dport nfs -j RETURN iptables -A aaa_persist -s "$nfsallow" -p udp --dport nfs -j RETURN iptables -A aaa_persist -s "$nfsallow" -p tcp --dport 32765:32768 -j RETURN iptables -A aaa_persist -s "$nfsallow" -p udp --dport 32765:32768 -j RETURN fi rules are the same on both client & server. What am I missing to make locking work and have a happy NFS setup?

MUUG Board Elections - FINAL CALL for Nominations
by Gilbert E. Detillieux 21 Sep '07

21 Sep '07

Hear ye, hear ye! This is the FINAL CALL for nominees to participate in the election for the MUUG board. Those elected will serve from October 2007 until October 2008. The deadline to nominate yourself, or someone else, is September 25, 2007. Instructions follow. The MUUG board is charged with coordinating the meetings and other events by the group. It's fun, and you get a role in guiding the group. All MUUG members are encouraged to apply. ------------------------ MUUG Board Elections - Call for Nominations Every October the Manitoba Unix User Group holds its Annual Meeting, the main goals of which are to elect a new Board of Directors and to pass any special resolutions. (Aside from that, it is a regular meeting) Any member in good standing can be nominated to run for a position. As of this writing, the following members of the current Board have let their names stand for re-election: Gilbert Detillieux Systems Analyst University of Manitoba Michael Doob Professor University of Manitoba Kevin McGregor Systems Specialist City of Winnipeg Doug Shewfelt Systems Specialist City of Winnipeg Adam Thompson Consultant athompso.net Shawn Walbridge System Administrator Frantic Films Of course, this list is just a starting point. Any member in good standing of the group can be nominated simply by getting the support of one other member. If you feel you would like to contribute to the group by running for a board position, please don't hesitate to do so. (In fact, we'd like to see the number of board members increase.) If you want to be nominated, or to nominate someone else, send a letter to the group's postal box or deliver it in person to a current board member. The letter must contain the name, title, and employer of the nominee, along with a short (100 word or so) biography, and must contain the signatures of the nominee and one other member. The letter must be received no later than September 25, 2007, which is 14 days prior to the October 9 meeting. Although the by-laws require that the nominations be done in writing, with signatures, you can speed up the process by sending us e-mail to <election(a)muug.mb.ca>, with the above information, and sending the signed paper copy later. In this case, please include the e-mail address of both the nominee and the supporter on the CC: list of the message, so that all parties concerned have a record of the communication. Nominees should familiarize themselves with the MUUG bylaws, found here: http://www.muug.mb.ca/pub/bylaws/ If you have any questions about the election or the nomination process, please contact Gilbert Detillieux, either by phone (474-8161) during business hours, or by e-mail to <election(a)muug.mb.ca> anytime.

IBM and OpenOffice
by Steve Moffat 20 Sep '07

20 Sep '07

This may not be news to some, but (from my perspective) this is a step in the right direction. There has been a lot of fuss inside ibm over the years to "give" the lotus office suite to the open source community. The main issue has been with some code IBM does not technically own being in the various products. It sounds like they may have found a way to make it happen... http://symphony.lotus.com/software/lotus/symphony/buzz.jspa Steve Moffat IBM Global Services sjm(a)ca.ibm.com (204)792-3245

Video Editing?
by Sean Walberg 12 Sep '07

12 Sep '07

I'm curious about what people use for video editing in Linux. I have a Sony Mini-DV Handicam, and now with a cheap firewire card I can pull video down onto my computer. I'd like to ultimately end up making DVDs and short clips to share with the family and keep with the photo albums. Kino is very simple, in fact I think it's too simple. After playing with it for a while I think I prefer Microsoft Movie Maker. I'd have actually gone that way (my Windows work PC is a lot faster than my Linux home PC) but the Microsoft tool can't generate DVDs directly. I've been playing with Cinelerra, which is in an entirely different league, almost like going from mspaint to Photoshop. Lots more features, but a bigger learning curve. In about an hour I figured out how to import the video files, edit the cutmarks, and splice them together with transitions, which is about all Kino can do. The kicker is to generate the final video you have to render it -- a 75 second clip with no complex stuff is taking over 20 minutes at DVD quality on my meager 1.8GHz P4. Any other recommendations or observations? Thanks, Sean -- Sean Walberg <sean(a)ertw.com> http://ertw.com/

Fwd: Countdown to Ontario Linux Fest
by Gilbert E. Detillieux 05 Sep '07

05 Sep '07

Just FYI... -------- Original Message -------- Subject: Countdown to Ontario Linux Fest Date: Wed, 5 Sep 2007 08:40:49 -0400 From: Interlug Lists <interluglists(a)gmail.com> To: lolug(a)googlegroups.com, mark(a)klug.ca, v.simon(a)ieee.org, blab(a)users.sourceforge.net, membership(a)muug.mb.ca, admin(a)nslug.ns.ca Hello LUG-gers! Please post this to your mailing list and / or web site! Thank you. We look forward to seeing you at Linux Fest in October! Cheers, Richard and the gang. Hello everybody, The countdown is on to Ontario Linux Fest and we couldn't be more excited. Here's some news from inside the organizing committee. Since our last note we've added some speakers and topics, and a couple of prominent sponsors. And a bunch more of you have registered in advance from our registration page at http://onlinux.ca/olfreg All of that is awesome, because we need all of those pieces in place to build Ontario Linux Fest. We're just a touch over a month to the Fest, so here are a few things that you need to know about. Novell goes platinum at Ontario Linux Fest. "Novell Canada has secured a key platinum sponsorship to further demonstrate their commitment to GNU/Linux and Free Software," said, John Van Ostrand of the organizing committee, "As members of the Open Invention Network, patrons of KDE and sponsors of OpenSUSE (and dozens of other F/LOSS contributions, Novell continues as community leaders." We can't make Ontario Linux Fest a success without our sponsors and we urge you to consider OLF sponsors when you are making purchasing decisions. Free your phone and your mind will follow. We're very excited about the OpenMoko presentation at OLF. The recent splash made by a proprietary phone has only tilled the soil for an Open computer-phone. Or is that a phone-computer? Or a media player? You'll want to catch every minute of Ian Darwin's presentation on the OpenMoko project to find out all the details on this cool bit of embedded hardware. We're still adding speakers as they confirm, so keep an eye on the speakers page. We can't make Ontario Linux Fest a success without our speakers and the F/LOSS world is a better place for their code and projects and other contributions. Hotel room countdown We have discounted group rates at two hotels near the venue. If you are joining us from out of town (or plan to stay late at the reception) you can save by booking your room now. The Radisson is right next door to the venue and has given us a great price for their suites. But book now because they only offer the group rate until this Sunday 09 September. The Doubletree is just across the street and the price for their rooms is still good. The Doubletree group rate is valid until Wednesday, 12 September. http://onlinux.ca/hotel Attendee registration is climbing It is gratifying to see many of you registering in advance for Ontario Linux Fest. Attendance is climbing steadily and we know that it will ramp-up steeply as we get closer to the event. You can help us by starting that ramp-up now. There is no reason to hold Ontario Linux Fest without you. It is the community and the personalities and the networking that will make the most lasting impressions on you at Ontario Linux Fest. It is the conjunction of the strong local community and the influx of visiting regional and international enthusiasts that will make OLF shine. We look forward to seeing you at the event.
