looking for a gadget
by Theodore Baschak 24 Oct '07

24 Oct '07

Good Evening Folks: Looking for a device like the following: <http://www.apc.com/resource/include/techspec_index.cfm?base_sku=AP7900> except only a single plug, and with a 2nd network port that does passthru like a wired voip phone. I love these power bars, but they're too large to fit into one of those 8x10 NEMA enclosures. Anyone ever even heard of such a beast? Theo

OT? Promise RIAD controller issue
by Raymond J. Henry 20 Oct '07

20 Oct '07

Good day. Wondering if anyone here has any working knowledge of Promise RAID controllers? Have an issue with my Gentoo box, and thinking that I should rebuild the array. Have mirrored 250 GB drives. The primary seems all good, but the second drive is missing a partition and ALL data by the looks of it. Looking at the options in the card BIOS, I see drive 1 with 0 bytes capacity, and drive 3 with 232 GB capacity. Am I correct in assuming this is just to keep you from writing stuff to the primary drive? If so, then I simply want to go ahead and rebuild the array mirroring drive 0 to 3, no? Just though I should ask rather than guess. Wouldn't want my guess to wipe it all out, and have to start from scratch.... :/ Thanks in advance.... :)

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

by gedetil＠cs.umanitoba.ca 02 Oct '07

02 Oct '07

The Manitoba UNIX User Group (MUUG) will be holding its next monthly meeting on Tuesday, October 9. The meeting topic for this month is as follows: GnuCash GnuCash is a free software accounting program for personal and small business use. It runs on multiple UNIX-like platforms. The presentation will cover some of GnuCash's features and also double as a fast introduction to bookkeeping. Potentially covered: account types, double-entry accounting, reports, invoices, bills, employee expenses, scheduled transactions, loan calculations, and demystifying "debit" and "credit." The presenter, Mark Jenkins, is a recent graduate of the Computer Science Honours program at the University of Manitoba. Mark has contributed a very small bug-fix patch to GnuCash but expects to contribute more in the next year; his employer, ParIT Worker Co-operative, recently received a grant that will fund additional development. 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).

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

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

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.

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.
