Re: CPU question
Most of the time servers are I/O bound. So it would be wise to spend your money on a good NIC, SCSI adapter, SCSI hard disk, fast (IO wise) MOBO, etc. If you can re-use the P166 then do it, otherwise put a nice celeron in your server and spend your money on the I/O stuff...

At the moment, it has a P166, and the load avg is around about 5. The highest once reached to 22. In Australia here, the price of getting two P550 and one P700 is roughly the same. So should I get two slower CPUs, or one fast CPU. Which case will the server run faster/perform better? Thanks in advance.

Primary and Secondary DNS one 1 server...
Because of an upgrade of our computer network I must run the primary and secondary DNS one 1 server with two NIC's for a while... Has anyone experiance with this? My guess would be to run named twice and point to two config dirs and edit the named.conf seperatly to run each named on the right interface... But thats just a guess! Regards, Onno

One step further (WAS: Re: Advanced hard disk mirroring!)
The high quality replies I received (especially from Jens B. Jorgensen) solved my problem. (see http://www.debian.org/Lists-Archives/debian-user-0001/msg02027.html) It also gave me an idea: Wouldn't it be great if there was ONE Linux boot-floppy that would mount (SMB or NFS?) a complete filesystem after the initial boot over a network (and complete the boot sequence?). I'm probable not the first who came up with this idea, so does anyone know If such a thing is already pulled off? Regards, Onno

Yes, that is what I ment, maybe I should put LILO on the hard disk and then set the default boot to the hard disk with an option to boot from A: ??? you can however install lilo on a floppy and have it boot the hard disk. Is there then realy no way to boot the floppy also WITH a DOS filesystem? Probably not :-( Thanks, Onno

Re: New drive ready to partition. Just what some recommendations and suggestions.
Hmmm, does incremental backups sound good in this situation? Anyone? Regards, Onno At 07:44 PM 1/18/00 +, John Gay wrote: I've got some good suggestions, and apparently raised a few questions as well. Let me outline my reasons for asking and what I hope to do: I've got a CD-RW. I plan to use this for back-ups as well as software publishing. I've also got a SCSI tape drive, but I'm not quite sure how to use it yet. I've got / as a 500M partition. This is perfect for putting onto a bootable CD-RW for emergency recovery. Being new, I've already screwed up my system to the point where it wouldn't boot. Last time I had to do a complete install. I would like to keep the other partitions small enough to put onto just a few CD's each. Worst-case scenario, I trash a complete partition, I can recover from just a few CD's. This also makes backing up each partition less work. I also want to have a few partitions set aside for CD images. I would feel better having a number of smaller partitions that I can back-up and recover quickly, plus fsck would run faster, that just a few really big partitions and lots of sym-links to hide the facts. I've read the multi-disk HOW-TO, as it has some good info on partitions sizes and such. I've also read the FHS info as well. I know StarOffice wants to install in /opt, and apt-get uses /var quite heavily. I expect only three users, and maybe a business account, so mail shouldn't be too much. At the moment I'm more concerned with being able to recover the various system and user programmes before I make my next mistake as root, rather than and user data. This would indicate a good scheme for recovering /usr. Probably spitting it up may help, as long as my / partition would have enough to recover the rest of the system in case of catastrophic failure. Thanks again for your input. I'll have another read of the FHS documents and a good think.
Advanced hard disk mirroring!
I'm a sysadmin and have two Debian GNU/Linux potato servers and 50 windows 95 workstations under my care. My problem is with the 50 workstations: (the 50 workstations have the same hardware) I want to install ONE workstation and then mirror the hard disk to all other workstations. The first time I did it was with ghost and I hooked up the installed hard disk to every client and mirrored it... Not a nice job to do and there must be a better way do do it! I know that ghost CAN use NETBIOS connections and such but I don't know how to boot it from a 1.44 flop and then use ghost. My question: I want to boot the workstation to be installed from a floppy with Linux or DOS. Then I want to make a connection to my server (or the installed workstation) and mirror the hard disk from a file (or hard disk). Frankly I don't care what is used or how it's being done (Linux/DOS with dd/ghost or something else!) but I don't want to hook-up all 50 workstations again... Thanks for any ideas, Onno
Re: New drive ready to partition. Just what some recommendations and suggestions.
Sometimes I don't understand the stratagies used in disk partitioning. Please correct me if I'm wrong but I always thought that you split the partitions by long term usage: 1- 2 GB / 1- 2 GB /var 1- 4 GB /var/spool rest on /home Then I link /tmp to /var/tmp WHY: The chance that / is being filled by a user is small this way. Email and printing activities are split from other partitions. Logging, tmp and such are split from other partitions. And last but not least home directories are split from other partitions. Ideas and critical remarks are welcome... Groetjes, Onno At 12:48 PM 1/18/00 +0100, Ron Rademaker wrote: I recently got a new 13G hard drive. I've installed it as hdb, and moved my CD-RW to hdc.

I really need more room for both /home AND /usr, but I also need more space for /var and /opt and some others. I would like to make several partitions and use them to my best use, I just wanted to get some recommendations from the Expert/Experienced before I partitioned this drive. I also would like to have a few partitions set aside for CD images as I hope to start selling Software on CD as well. I don't know if you're willing to reinstall completely or just want to add the space, if you're willing to reinstall I would: 1) Your current hd 4 GB on / 2) New hd 5 GB on /home 3) New hd 8 GB on /usr That way you'll have more on /home, /usr, /var and /opt (both /var and /opt will be on /). If you don't want to reinstall you could set a 5 GB on /home and remount your current /home to /var or /opt (whatever you prefer). That way you'll have more on /home and on /var or /opt. Then you create the 8 GB, mount it somewhere, cp the /usr to that partition, following you mount your current /usr to /var or /opt (just the one you hadn't used) and mount that new partition to /usr. (It'll probably need a reboot because you can't umount your /usr (maybe you can after a init 1 (runlevel 1 single user), I've never tried).
