Actually, Novell has the right to waive those claims, not just the copyright. TSCOG is agent for Novell, not owner of the contract (that's why the contract says 100% to Novell, who remits a 5% fee to SCO) - TSCOG has ownership of code developed after the sale. Not the overall rights. Quick check - SCO is still claiming unfair competition, interference in contracts, and interference in business relationships, based on their last report on the case to the judge, after Judge Kimball ruled for Novell (which it looks like this is the jury trial confirming) - ref: http://groklaw.net/pdf/IBM-1079.pdf Of course, they have to prove those claims. In any case, there are still some rulings left in the SCO vs. Novell case that are before Judge Stewart. Agreed - we'll see how it goes. Of course, Darl's admission on the stand that they didn't need the copyrights to conduct Unix business should be pretty devastating to their case. ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/

While these facts might be true (and from what I have read are quite true), the lawsuit covers all 3. Essentially, the SCO vs. IBM case has not been adjudicated, regardless what IBM claims, it is up to the court. IBM has been claiming from day 1 that the derivative clause itself was waived by ATT. It comes down to contract law. And, while Novell currently owns the copyrights, TSOG retains the contract rights. This is why Microsoft and Sun went to TSOG, not to Novell. That was the other issue in Utah regarding the royalties that was resolved and not appealed. TSCOG issues and maintains the licenses, and must pay some of the royalties to Novell. -- Jerry Feldman g...@blu.org Boston Linux and Unix PGP key id: 537C5846 PGP Key fingerprint: 3D1B 8377 A3C0 A5F2 ECBB CA3B 4607 4319 537C 5846 signature.asc Description: OpenPGP digital signature ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/
[GNHLUG] Vim - how to learn more - CentraLUG, April 5th
The April meeting of the Central New Hampshire Linux User Group, CentraLUG, will be on Monday, April 5th, at the New Hampshire Technical Institute's Library, Room 146, starting at 7 PM. Directions and details always available at http://www.centralug.org Ted will talk about Vim the text editor. Developed by Bram Moolenaar and originally released for the Amiga (on Fred Fish 591!)[1], Vim was based on the vi editor by Bill Joy (and he, in turn was inspired by ex, etcetera...). No expert, Ted will talk about what he's learned and where he learned it, resources that are out there to learn or enhance the basic functionality, and a demonstration of what he's learned so far and how far he has to go. We'll talk about resources you can use - websites, cheatsheets, videocasts, books - online and paper version, a really cool one-liner, add-ons and plugins and more! Beginners interested in learning about Vim are welcome. Experienced practitioners and experts are welcome to share their insights and suggestions on how to learn more. Emacs users are welcome to make constructive comments. As always. we will have a question and answer session, announcements, job openings, folks looking for jobs, and general camaraderie. Hope to see you there.

NFS stops responding
I've run out of clues (EBRAINTOOSMALL) trying to solve an NFS puzzle and could use some help getting unstuck. Analysis is awkward because the customers in question are trying to make what use they can of the machines even as these problems are ocurring around them, so reboots and other dramatic acts have to be scheduled well in advance. Symptoms: after approx 1 hour of apparently normal behavior, operations like 'df -k' or 'ls -l' hang for minutes at a time and then fail with I/O errors on any of the three machines when such operations refer to NFS mounted directories. At that point, doing this on all 3 machines: umount -f -l -a -t nfs ...followed by this: mount -a -t nfs ...on all 3 gets things unstuck for another hour. (?!?!) The 3 machines have NFS relationships thus: A mounts approx 6 directories from B (A-B) B mounts approx 6 directories from A (B-A) C mounts approx 6 directories from A (C-A) (same dirs as in B-A) C mounts approx 6 directories from B (C-B) (same dirs as in A-B) All systems are running x86_64 CentOS5.4 on HP xw8600 workstations connected via a Dell 2608 PowerConnect switch that's believed to be functioning properly. No jumbo packets. All MTUs are the standard 1500. I've tried specifying both UDP and TCP in the fstab lines. I've disabled selinux. The output of 'iptables -L' is: Chain INPUT (policy ACCEPT) target prot opt source destination Chain FORWARD (policy ACCEPT) target prot opt source destination Chain OUTPUT (policy ACCEPT) target prot opt source destination These commands: service nfs status ; service portmap status ...indicate nominal conditions (all expected daemons reported running) when things are working but also when things are b0rken. There wasn't anything very informative in /var/log/messages with the default debug levels but messages are now accumulating there at firehose rates because I enabled debug for everything, thus: for m in rpc nfs nfsd nlm; do rpcdebug -m $m -s all; done After machine A exhibited the problem I *think* I see evidence in /var/log/messages that the NFS client code has decided it never got a response from the server (B) to some NFS request, so it retransmits the request and (I think) it then concludes that the retransmitted request also went unanswered so the operation is errored out. I gathered some Enet traffic for Wireshark anlysis on both machines thus: dumpcap -i eth0 -w /tmp/`hostname`.pcap ...and viewed the client traffic with Wireshark, which (apparently) confirms that the client did indeed wait a while and then (apparently) retransmitted the NFS request. The weird thing is that Wireshark analysis of corresponding traffic on the server shows the first request coming in and being turned around immediately, then we later see the retransmitted request arrive and it, too, is promptly processed and the response goes out immediately. So, if I'm reading these tea leaves properly it's as if that lost the ability to recognize the reply to that request. [?!] But, then, how could it be that all 3 machines seem to get into this state at more or less the same time? and why would unmounting and remounting all NFS filesystems then fix it? Aaaiii!!!

NFS stops responding
After machine A exhibited the problem I *think* I see evidence in /var/log/messages that the NFS client code has decided it never got a response from the server (B) to some NFS request, so it retransmits the request and (I think) it then concludes that the retransmitted request also went unanswered so the operation is errored out. So, you have a path client - switch - server (request) - file system - server (reply) - switch - client. And that's a simple setup. Add automount and NIS maps and then you'll have real fun. I gathered some Enet traffic for Wireshark anlysis on both machines thus: dumpcap -i eth0 -w /tmp/`hostname`.pcap ...and viewed the client traffic with Wireshark, which (apparently) confirms that the client did indeed wait a while and then (apparently) retransmitted the NFS request. The weird thing is that Wireshark analysis of corresponding traffic on the server shows the first request coming in and being turned around immediately, then we later see the retransmitted request arrive and it, too, is promptly processed and the response goes out immediately. So, if I'm reading these tea leaves properly it's as if that lost the ability to recognize the reply to that request. [?!] Sounds that way. I learned to hate network switches when I was doing GbE performance work with NFS. I also got a phone call at 2230 one Friday night before a blizzard about a customer with inscrutable NFS problem, ultimately traced to their new router they didn't think of telling me about. (And a panic in code that choked on malformed NFS packets which was actually helpful in fingering the router as the corrupter.) Oh, this problem. So you're seeing the replies leave the server. That's good, it means you're talking about a networking problem, not hung file systems or such stuff. It also means your subject line isn't quite right. That's okay, happens all the time, but do note the server _is_ responding. The packets are getting lost. The client isn't seeing the replies? Blame the router, blame the router! Except - take a closer look at those replies. In the IP protocol is the destination address the client? Look at the Ethernet protocol, is the destination address the router? If both are true, then the router must be seeing the replies, but isn't sending them on to the client. Where are they going? Check statistics in the router (if you can, another reason to hate routers). Check the ARP table in the router (if ... hate ...). My guess, and I'm getting really rusty on this, is perhaps some other system is using the clients IP address (fail - all 3 clients get lost? that's unlikely. Check routing tables if you can (... hate ...). Simplify, simplify, simplify. One challenging thing about chasing NFS problems with NFS is that oftentimes the problem is not NFS. However, NFS is often the dominant traffic source and people are surprised to see that telnet/ftp/ssh don't work either. You can't get much simpler than ping - start a ping from client - server. If you stop getting ping replies the same time you stop getting NFS replies, then don't worry about NFS. Fix ping. Routing tables. ARP tables. But, then, how could it be that all 3 machines seem to get into this state at more or less the same time? and why would unmounting and remounting all NFS filesystems then fix it? Aaaiii!!! If it is related to something like IP address reuse, it may be that by doing unmounts you stop the NFS traffic long enough for the clients to send out an ARP message stating they have the IP address and hence reclaim it. I'm skeptical that's the problem, but it might be related. Oh, it's still up - check out http://h30097.www3.hp.com/tipnfs.html I wrote that ages ago to keep people from pestering me with NFS problems that were not specific to NFS. Oh - another thing that can do you in. Verify that the IP messages and NFS messages are lengths that the recipient can understand. If one system uses jumbo frames and the other doesn't, things work just fine for small files and small directories and then something wedges because a message is too long. Same for NFS messages - I saw one case where the client said it wanted 64KB I/O, the server reported it could offer 64KB I/O, but the caching NFS system in the middle only handled up to 32 KB NFS messages. Bring bubble wrap to pop as needed. ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/
