Mary Gardiner wrote: Thanks, but in my case (if you were responding to me) the machine panics well before I even have the opportunity to login, even in single user mode. It might help Rod. Yes, the comments were for Rod's particularly. In the case of your original post I did not comment because I did not have sufficient understanding of the issues. For example, what is the linux kernel version you are trying to upgrade from ? What are the logical device names for this SATA device in the original version of linux you are upgrading from ? This is important. If you are upgrading from linux-2.4.X, then there are certain things that needs to be done, e.g., you have to upgrade your modutils software; create a directory /sys, etc. If you are upgrading from 2.5.X or later, then it maybe just a question of using RAW device reference as follows: My suggestion that you may try is use RAW device reference as follows: root=08:01=/ instead of root=/dev/sda1=/ As you know, '08:01' is just another reference name to device '/dev/sda1'; '08:02' is just another reference name to device '/dev/sda2', etc. Perhaps, at the boot process stage your device driver does not understand the device logical name, and that is why I suggest you use the other name of '/dev/sda1' which is '06:01'. In this way, no logical translation is required at boot time. I assume you can do the above because you can boot off your original system that is to be upgraded. -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html

RE: [SLUG] NTPD FC3
Are you sure it is rejecting the source port? From reading the doc the default should be that it accepts from any port. Have you checked NTP version support - I imagine the FC3 ntpd is by default version 4 and hence your older clients may not support that. Try setting version 3 or 2 in the config. If you really think you that it is rejecting the non-123 packets then I guess you could possibly use NAT/masquerading on the server for those specific hosts.

RE: [SLUG] Mega X machine spec - ideas?
You probably want to use sar or the like on your existing machine to get a baseline understanding of CPU/disk/network etc. Hopefully you can extrapolate requirements from that. If the application onf the server is particularly critical you might want to consider using a hardware loadbalancer to front a server farm with a pair or more servers. This will give redundancy as well allow you to scale as performance requires it. You could even consider using blade servers if space/managability is an issue.

Beowolf clusters are not an option TIA Stuart Guthrie Are all 80 users going to be concurrent users? I've run 30 concurrent users in an LTSP environment satisfactorily off an x86 machine (1GB RAM and dual PIII). The main problem I found was disk access speed and the network connection was only 100MBit. The situation was such that the users were literally concurrent - it was a school with 2 classes logging on and doing exactly the same thing at exactly the same time. CPU was no problem really, nor RAM, although with an app needing 64MB per instance(?) I'd be getting as much RAM in there as it could hold to handle the app and the X session. I've got no specific suggestions apart from that. The server I was using was a HP server, which is still going.

RE: [SLUG] NTPD FC3
How stupid is it possible to get. It helps when writing filter rules on the fly to actually put in a jump instruction rather than letting the checks fall thru to the default block at the bottom. Duh. Sorry for the noise. On Tue, 2004-12-07 at 18:09, Visser, Martin wrote: Are you sure it is rejecting the source port? From reading the doc the default should be that it accepts from any port. Have you checked NTP version support - I imagine the FC3 ntpd is by default version 4 and hence your older clients may not support that. Try setting version 3 or 2 in the config. If you really think you that it is rejecting the non-123 packets then I guess you could possibly use NAT/masquerading on the server for those specific hosts.

My reading of the man page would suggest that putting 'non-ntpport' in the 'restrict' line of your /etc/ntp.conf should do the trick. Ya, I fond the comment in the doco rather than the man page, but the small problem is that it appears not to work. If I mod the line to read: restrict 192.168.252.0 mask 255.255.252.0 nomodify notrap non-ntpport then it still won't respond to unpriv source ports.

RE: [SLUG] Mega X machine spec - ideas?
Yes, a Sun SMP hardware with x86 card(s) might do the job. The main feature would be a very fast TCP stack, with the x86 part handled by the cards. You could always have it looked-at in something like the Sun iForce centre or the Securedata Fishbowl (if they still exist - Securedata got taken over recently I think by Dimension Data). Linux should run OK on the SMP box but I'm not sure if they have ported their x86 processor switching to Linux. Might have to be Solaris. Either way you will need a fair bit of RAM and maybe a couple of SPARC CPUs. Last time I used an x86 offload engine it was pretty slow. Another option is to go Opteron, which will emulate x86.

Here's a spec to please the taste buds... I've a customer who has been win4lining for a couple of years with great success. Their setup goes: Windows PC. Cygwin. ssh -XCf -- Linux Box -- /bin/win (win4lin runs on remote box, X forwards back to the Windows PC. They are looking at going from about 15 users to 80 users. This means a machine upgrade of sorts. I was wondering what sort of spec 'intel'-wise you would use to run: 80 users logged on using X windows. Forwarding to Windows PCs via SSH -XCf Those users will all be running win4lin. The windows app is a semi-intensive client/server arrangement that generally requires about 64Mb at least of RAM to run. There is minimal requirement to access disk on that machine. There would be major network traffic happening. I would imagine that 80 ssh sessions would also generate a fair amount of CPU usage.

Re: [SLUG] Mega X machine spec - ideas?
If you're doing Linux and want to put up with some non 64-bit apps, I'd recommend Opteron 2xx or better, running Fedora x86-64/Win4Lin and NX server. This way, clients don't need to know squat in order to connect cause the NX client is much easier to install and configure than Cywin. And yes, I've done it both ways, prefer NX by a long shot. www.nomachine.com Rowling, Jill wrote: Yes, a Sun SMP hardware with x86 card(s) might do the job.

[SLUG] migrating home directories
Hi all,
I am trying to migrate the home directories of our users onto a SNAP
Terabyte server. The issue I am having s one of preserving ownership on
hte files and directories.
This is what I have tried:
I have mounted the terabyte server into /mnt/snap using NFS and Samba (not
at the same time of course!).
1. Used cp -dpr - copies the files and directories OK, but gives
'Operation not allowed' when trying to set the ownership.
2. tar -cf /mnt/snap/filename {home directories} then tar -xvf on the
resultant file, again it create the directories but gives errors such as
Cannot change ownership to uid 6209, gid 6209: Operation not permitted
when trying to set the permissions, I have confirmed that the uid and gid
correspond to the relevant user in /etc/passwd
I can't see nay log entries to indicate any other issues.
Any clues appreciated
