Re: Apache dies silently?
You're probably using unstable, are using PHP4 packages, and do not include PHP4 support with apache-ssl. Your system probably chugged along happily because you haven't done any apt-get update apt-get upgrade for a while. At least, that's how I got burned. There's some kind of conflict with PHP4 and apache in Unstable. The following worked for me: more /etc/apt/preferences Package: php4 Pin: release a=stable Pin-Priority: 1001 Package: php4-mysql Pin: release a=stable Pin-Priority: 1001 Package: php4-imap Pin: release a=stable Pin-Priority: 1001 Package: php4-cgi Pin: release a=stable Pin-Priority: 1001 Package: php4-pear Pin: release a=stable Pin-Priority: 1001 Package: php.* Pin: release a=stable Pin-Priority: 1001 Package: * Pin: release a=unstable Pin-Priority: 500 (Pins the PHP4 stuff to stable until this mess gets straightened out!).

Re: Anti-Spam ideas for usenet/list harvested email addresses
should be able to help in some way, either by adding to the EHLO command set or something on the users web site. There have to be better and still simple ways of doing this that make it cost much more to find our email addresses than it costs us to filter the junk. True. But you still don't solve the problem of having someone easily contact you off list. In the case of this email, I've decided I have something worthwhile to say on the topic at hand (or I'm bored, and want to babble about email filters...) so I hit reply to all. If I had to break my train of thought to sift through your website to find your email address, I'm probably not going to bother. Also consider the fact that some people do have to read email offline, and rely on the assumption that all necessary contact info is contained in the email itself. Enhancing EHLO would probably not be realistic, given that virtually all email clients would have to implement it. It's like saying oh, just turn on SMTP authentication, and we can be sure that the sender isn't a spammer, or at least can track them down. Images with pictures of your email address is fine, but again, it's just a slightly more difficult form of jacob at cachevalley dot com... eventually wouldn't the spammers just create OCR software that looks for email addresses in images on websites linked from your website? The sad part is that I've already squandered my username at this email address by putting it where it can be harvested in mass by worm/virus and UCE/UBE collection scripts, and I had already read an article cautioning me against this. Oh well live and learn (someday I'll learn anyway.) I'm going to look into setting up a new email address with mail server rules for delivery driven by a user supplied whitelist after waiting a few days for comments and flames on this idea. If you know of links to pages already discussing how to do this with postfix, please share them. Look to SpamAssassin. That will make a huge dent in your spam problem. Tack on Amavis for the latest in MS malware, and you're in business. I believe both integrate fairly well with Postfix. Amavis is also able to reject viruses during the SMTP transaction. This I would agree with, if your configuration allows it. Some good thoughts there... but I wonder just how many mailing lists would need to apply such a solution to make an impact, and how difficult it would be to apply. OTOH, you might find better results with simpler methods... --Rich _ Rich Puhek ETN Systems Inc. 2125 1st Ave East Hibbing MN 55746 tel: 218.262.1130 email: [EMAIL PROTECTED] _ -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

Unfortunately (or fortunately, depending on how the blocking works), some of the newer worms do not use the smarthost, but instead they use their own little SMTP engine.

Re: SMTP over SSH
How about setting up your laptop to have SSH forward local port 25 to mail server port 25? No changes to exim, change your MUA to use localhost as your SMTP server, change your SSH client to forward localhost:25 to (your_smtp_server):25 and life is good. No need to 'bind' ports 22 and 25, SSH can do this on its own. If you're running linux on the laptop, look at ssh -L. If you're running another OS, look at the docs for the SSH client. I believe putty can do this, and I know that Tera Term SSH can do it. --Rich Alex Malinovich wrote: I have my laptop set up to work fine with my home mail server from just about anywhere.

Re: Code rights for employees (was Re: SCO identifies code?)
Steve Lamb wrote: So do you think that any artist would sign on and say that x type of work is owned, whole or in part, by the company regardless of whether or not the work was done for that copy or on their own? If they did, that would be their own fault, wouldn't it? It also wouldn't be the first time a starving artist took a deal that turned out to be not so beneficial (think of most of the VH1 Behind the Music specials, or the Prince fiasco of the early 90's). Actually, when was the last time you saw a rock star tell a record label you know, I wrote this song on my own time, so I don't think you really own the rights to it? Granted DC Comics owns the copyright for Sandman and Warner Brothers owns the copyright for Babylon 5 so one can argue that if Neil Gaiman or JMS write stories in those universes they can be considered property of the companies that own them. But the larger argument of th genre cannot be made. IE, JMS still can (and does) write science fiction even though that may compete with the WB property Babylon 5 which is science fiction. He can't call it Babylon 5 or relate it to Babylon 5 but he can write it, sell it, whatever even if it were during the time he was working for WB's project provided it was on his own time. Then apparently, JMS is not forbidden to do so by contract. If he signed a contract that stated he would not do ANY Sci-Fi writing for any other bodies, then he would not be able to write, sell, or whatever, even on his own time. This is an assumption, however, based on your observation that he continues to write science fiction. We don't know for sure if he's contractually forbidden to write science fiction unless we have a copy of his contract :-) It is the same principle here. If an author working on eBay (to keep with the example) goes on to found a competing on-line auction site as long as there is no code share and none of the work was done on eBay's time then eBay has no claim as long as he doesn't call it eBay. IE eBay = title, auction site = genre. Again, this assumes that the author working on eBay did not sign a noncompete contract. If he was a key developer, I would not be surprised if eBay's contract stipulated that should the author leave eBay, that he not work for any other online auction sites (at least for a period of time, or within a geographic area). It's fairly common practice in different industries (heck, I can't talk to my old insurance agent for another couple of months, since he had a noncompete signed with his old insurance company). The arguments made so far are putting words into employment contracts, or assuming that no contract exists. IANAL, but it seems that there are several questions here: 1) Did the employee sign a contract? no: It's likely that the employee retains ownership of everything done on their own time, with possible IP exceptions, depending on copyright law, and IP laws of their state. Yes: 1a) did the contract contain provisions regarding ownership of intellectual property, inventions, copyrights, etc? If the contract did, it is likely that in signing the contract, the employee VOLUNTARILY AGREED that any inventions, code, etc. are the property of their employer, even if done on their own time. 2) What do state and federal laws dictate in the absence of a contract? 3) Can a contract impose ownership restrictions even if state and federal law do not? 4) Can/do state and/or federal law place limits upon what IP, code, copyright, etc. rights may be contractually transferred to a company as part of an employment contract? --Rich _ Rich Puhek ETN Systems Inc. 2125 1st Ave East Hibbing MN 55746 tel: 218.262.1130 email: [EMAIL PROTECTED] _ -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

I had a similar problem develop here. All I had to do to fix it was have my DHCP server return a WINS server attribute (and wait around 15 min for windows to figure out what the hell was going on).

Result is that users configured for TLS get a warning that hotnames don't match. I've started digging through the OpenSSL docs. Looks like all I need to do is regenerate the certificate interactively, and specify the desired hostname, overriding the default. Problem is, I'm not sure about any other switches I'll need.

Re: spamassassin installation help
This is doable, but the problem is with spamc - it depends on a newer version of libc6 than what is in Woody. This means that if you want to install the spamc from unstable (which you must to satisfy the Depends: for spamassassin) you have to upgrade libc6 as well. I run Sid on one of my boxes, without any real problems, but I wouldn't want it running on a mail server. I found it much easier to backport for Woody than to mix distros like this, but YMMV. Ahh, that's right. Forgot about that. I'm running spamd on a dedicated box. Didn't have any trouble with the libc6 upgrade, but wouldn't have done that on the mailserver itself. --Rich _ Rich Puhek ETN Systems Inc. 2125 1st Ave East Hibbing MN 55746 tel: 218.262.1130 email: [EMAIL PROTECTED] _ -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

I'm not saying that this is an ideal solution, but could you install a cheap 4-port switch (not hub!) every 100 meters? Since switches generates signals themselves, rather than just passing the original electrical signal, that might extend your range sufficiently. Anyone care to tell me if or why this is a bad idea? You are correct about switches regenerating the signal, but why not just connect the two networks with fiber. Fiber will cost the same (or possibly less) to run between the two locations, will eliminate the need for multiple switches, and as a bonus will eliminate issues like grounding concerns (I'm guessing the two locations are in seperate buildings, if so, grounding and lightening protection become a hassle with copper). Toss a media converter on each end (or a fiber card for a router or switch), and you're set. As a further bonus, you'll easily be able to upgrade to higher speed networking between the ethernets just by replacing the equipment on each end. --Rich _ Rich Puhek ETN Systems Inc. _ -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

A device is a device, right ?? Whether it's a network card, hub, or switch, keep the distance between them under 100 meters. Sounds logical ;-) Wrong... The following: (PC#1)-HUB-HUB--(PC#2) is NOT the same as: (PC#1)-switch--switch-(PC#2) The problem is, a hub just electrically connects the signal (handling crossover, etc). A Switch will completely regenerate the signal on the other port(s). The overall length applies to each segment. The top diagram is one segment, which can have an *overall* length of 100 meters, not 400 meters as your analysis might imply. The bottom diagram can have 100m between the first PC and the first switch, 100m between the two switches, and 100m between the 2nd switch and the 2nd PC (assuming 10 base-T Ethernet). The issue, IIRC, has to do with the minimum size of an Ethernet frame, the speed at which the frame propagates down the physical wire, and the need for all devices to be properly able to sense a collision. Basicly, if the overall length of the network is too long, PC#1 could begin transmitting a frame while listening for a collision. PC#2, if far enough away, could start transmitting a frame at nearly the same time, also listening for a collision. If the network is long enough to introduce enough delay that the start of the frame transmitted by PC#1 did not reach PC#2 before PC#2 was done transmitting (and if the frame from PC#2 did not reach PC#1 before PC#1 was done transmitting) neither side would detect a collision. The result would be a corrupted packet, which would hopefully be handled at a higher layer. I'm a test engineer by trade, not a communications engineer, so my explanation may be a bit off.

I've found that the first time I open a large maildir folder the disk will crank for a while. I expect it would do just as bad if it was mbox, probably worse.

I've done this on about eight different systems, with few problems (had one box with an old-format /etc/lilo.conf file that caused me some difficulty when I rebuilt the kernel, but that's about it).

As you can see, it is a 54MHz PowerPC chip with 16MB of memory; not a powerhouse by any means. it is a powerhorse when it comes to video capture though. i have a tivo and i also do a ton of video capture from it(i haven't hacked it, not going to touch the insides of it until tivo goes under and i dont have any other choice). i have a 1.3ghz athlon with wintv pci and 768MB ram with a dual 20GB raid0 array. tivo can easily encode in ~640x480(approx what NTSC is). wintv on my athlon struggles to encode at 320x240. infact i make it a point NOT to move my mouse cursor when capturing otherwise it will drop frames. CPU isn't really a factor as the cpu hovers between 15-45%. just the slightest movement of the mouse and it drops a frameor 2. its a very fragile setup, i restart X frequently and i disable opengl in my nvidia drivers when i want to capture, and re enable it when i want to play unreal tournament. otherwise it drops more frames. I/O is not a limitation either, the video is encoded at a compression level that drops the bitrate to ~90kbyte/second. so adding a 50-disk raid0 array wont do anything. One thing to remember is that the Tivo has a few minor advantages: 1) Your serial port/USB port probably has a fairly high-priority interrupt, this is why your mouse movement will cause your processor to stop working on the encoding. 2) The Tivo probably has hardware dedicated to the specific purpose of video processing (a FPGA/CPLD type device, or maybe even an ASIC), where as your PC has to make do with a general-purpose microprocessor. 3) Your microprocessor is a CISC device (i386 class, etc are all CISC processors). I would guess that it is quite likely that the different execution times for the different instructions would be a challange in a realtime (or near realtime) environment. The PowerPC is a RISC chip, which (among many other things...) means that every opcode on the chip will average about the same (around 1.5 to 1.7 cycles/instruction IIRC). It may not be a real big deal, but then again, might be interesting to see how performance is with Debian on PPC. --Rich _ Rich Puhek ETN Systems Inc. _

Basicly, you will lose one hard drive to the RAID 5 parity data, so if you have 10 drives of 10.8 GB each, you'll lose 10.8 GB. If you have 3 drives of 36GB each, you'll lose 36GB.

Re: NFS tries following remote symlinks as if local!
Adam, Perhaps a hard link would work in the manner you're looking for? It does appear that there is no way to disable this behavior (as applied to symlinks). Note that NFS servers will return the pathname of a symbolic link, regardless of whether it is absolute or relative (the server really doesn't care... just happens that one answer starts with a /). You might want to pick up the O'Reilly NFS book (Managing NFS and NIS). It's kinda handy for the little NFS oddities like this. Don't be too hard on people who seem to underestimate your knowledge of a subject... often it's easiest to start from a certain point in an explanation to be certain everyone's on the same page...

But if I try to change to a remote symlinked directory I get, for example: this is normal and expected behavior. all a symlink is is a pointer. it points to a file. even if a file doesn't exist. Nate as you can gather from my follow up post I have a higher level of understanding than that. The remote symlink points to the correct location on the remote system. Having always used Samba for remote file accesses (so I could also access the files using a Windows machine) I expected NFS to follow remote symlinks on the remote filesystem (just like when I navigate a file system when ssh'ed into a remote box). I've learned an important lesson. Since I primarily use symlinks to hide the underlying file system layout I just expected the symlinks to continue to act transparently. Though I can see the point of Dave's Good Thing response. If I am backing up the files on my remote computer I will have to be careful to use the -d option in cp. Otherwise I will also back up parts of my local computer as the remote symlinks translate to local paths on my computer. I just tried converting my absolute symlinks to relative ones. But it still doesn't work (because it appears I don't have the ability to descend into mounts). Here's the scenario: I'm in the NFS mount point on my local computer. I ls -l and see this particular link. home - mnt/data/home So if I cd to home I should continue down the remote filesystem. Note that there is no slash (/) before mnt. This is a relative path. But it doesn't happen. Instead the mnt/data directory is empty. It appears NFS doesn't descend into mount points either. I've tried adding the nohide option to disable this but it made no difference.

Re: Making a TCP or UDP or Unux Socket Server Listen on a port
From man services: services is a plain ASCII file providing a mapping between friendly textual names for internet services, and their underlying assigned port numbers and protocol types. So... that file is just a way to translate between port names and numbers, not a magic way to make a program listen on that port. You are correct in that your entry would associate a.out with port 9889, in that once you get the program running, a netstat would show a.out listening on port a.out instead of port 9889. When you run your server program, try running a netstat. Do you see something on port 9889? If so, look at how the client is contacting it.

Re: exporting /usr NFS for small network
Richard Cobbe wrote: Lo, on Wednesday, October 24, joe golden did write: I am getting tired of updating 7 machines. I have home directories exported NFS for our network (with minimal security concerns) and this seems to work fine. My question is how do I export usr NFS. What are the configuration issues. How must disks be partitioned? Are all the X/card and monitor specifics guaranteed to be all in /etc? If any of these specs are in usr I'll have hashed spaghetti flying everywhere in no time. So long as the distributions in question follow the FHS (see http://www.pathname.com/ for details), then sharing /usr like this is fine. According to the FHS, /usr is for shareable, read-only data; config files belong in /etc. I'm pretty sure Debian qualifies here. I don't think partitioning is relevant to this situation; NFS exports files and directories based on the directory structure, not the physical devices. I was looking for advice on pitfalls to avoid. The only thing I'm not sure how to do is keep /usr/local local to each machine, even though /usr is mounted across the network. This may or may not be a requirement in your situation, however. I don't think you need to worry about that. From FHS 2.2, section 4.9.1: The /usr/local hierarchy is for use by the system administrator when installing software locally.It needs to be safe from being overwritten when the system software is updated. It may be used for programs and data that are shareable amongst a group of hosts, but not found in /usr. So you shouldn't need to keep /usr/local seperate on each machine. If your particular installation required such an arrangement, you could mount /usr from an NFS server, and then you should be able to mount /usr/local from a local partition if required. If a need for different /usr/local is present in your environment, you will have a concern here. A possibility is to have your NFS server export something like: /export/usr, /export/usr/local/flavor1, and /export/usr/local/flavor2. Then, on your machines you would do the following: on machines that need to have flavor 1 of local: mount nfsserver:/export/usr /usr mount nfsserver:/export/local/flavor1 /usr/local on machines that need to have flavor 2 of local: mount nfsserver:/export/usr /usr mount nfsserver:/export/local/flavor2 /usr/local (bad example, since I believe you'd have to export HTH, Richard -- Rich _ Rich Puhek ETN Systems Inc. _

Re: Sendmail directories... /var/state/sendmail...
Ian, Those directories are used to store state information about hosts your sendmail has tried to contact. By storing the info here, sendmail can check to see what the last state was of a host it may have recently tried to connect. The idea is that if you have multiple queue runners delivering mail, each runner knows if a host is already known to be down, and won't waste its time trying to deliver there. You are correct in that it's kind of a reverse hash, with top level domains under /var/state/sendmail (or whatever directory you specified with HostStatusDirectory) and that subdomains exist under there. The bat book has more info on the guts of the files you find there, if it's any concern to you. It also suggests that you try enabling and disabling persistent host status to see which is best for performance on your system. Anyone have any comments on running that on a filesystem other than ext2? I've noticed that a df of that directory (or even a simple ls of the com subdirectory) can take a long time on ext2. Perhaps reiserfs or something like that might be better suited for such a directory? --Rich Ian Perry wrote: Hi, I have noticed some wierd directories on one of our mail servers, and so I checked the others. hey are on all of them in some varying degree or another. /var/state/sendmail then ae. at. au. etc (SNIP) I can see that these are in reverse order... such as acay.com.au Is this a quick DNS lookup or what purpose do they serve ?

Re: centrally managed bookmarks for multiple users, accessible from everywhere?
The easiest way to have a shared bookmark is to just have a links page... just raw HTML. Your users could connect right to it by typing it in, could make it their home page, etc. A more advanced step would be to write something like a PERL CGI or a PHP program to allow the users to update the page. Even more advanced (Perhaps overkill) is to store the info in a MySQL database, and have the page generate automagically. MySQL would not actually be the program listening, your central machine would have a webserver running for the users to connect to. If you want to integrate the bookmarks into a browser, just have the clients synchronize their bookmarks file with the master file, either manually or through a cron job. The actual transfer could be ftp, wget, rsync, etc. If you've got NFS mounting, you could have some neat tricks with an NFS mount and symlinks, etc... --Rich Walter Tautz wrote: I was wondering if it would be possible to keep bookmarks on a central machine where one could access and change them via any browser than can ``connect'' to the bookmark server.

Re: Adaptec Raid
Michael, You need to patch your kernel to add the necessary drivers that support the Adaptec card. Adaptec hasn't gotten the message that Linux is not RedHat, so it's not a trivial process. See: http://people.FreeBSD.org/~gibbs/linux/ for the necessary patches for the kernel. If you're trying to boot off of the array you'll need to create a custom boot floppy. If your boot partition (and probably your root partition) are running off of the other SCSI controller, you can start the install, then patch the kernel. That part (custom disk) gets tricky, but it's doable. Basicly, you'll compile the kernel on another box, make a copy of your boot disk, and replace the kernel image on the boot disk with your new image. I've got the 2100S running fine for the last few months on a box I did this too. Once I get off my lazy butt I'll post images of my boot disk somewhere to save the headache of creating your own.

Re: Reiserfs and disk spindown: separate /var partition?
Craig and Christian, The Filesystem Hierarchy Standard, or FHS (http://www.pathname.com/fhs/) helps decide what can be mounted on a different filesystem. Some excerpts from the 2.2 standard: /bin contains commands that ...are required when no other filesystems are mounted (e.g. in single user mode). /sbin contains binaries essential for booting, restoring, recovering, and/or repairing the system in addition to the binaries in /bin. The FHS also encourages small root partitions, which would seem to imply that it's a good idea to give /usr a seperate partition. IMHO, in virtually all cases, /var should definately be in its own partition, since otherwise you risk filling the root partition with log messages, etc. --Rich Craig Dickson wrote: (snip) - Getting it right for the boot process (should I make / reiser or ext2?): I assume I need to have /etc, /bin and /sbin on the root partition.

I would guess that that would not be a good idea, since the boot process might (?) need access to them before it gets around to mounting all the default filesystems (for one thing, the mount command itself lives in /bin), but I'm not really sure. /usr can certainly be a separate filesystem, though I've never done so except when I wanted it to be on a separate hard disk from the root.

Re: [users] Re: a quickie
Also, if you're running, oh, say, and email or web server on you server rack, you might be concerned if the server were rebooted, since the service would be unavaliable for a while. On a heavily-loaded email server with a large (ext2) mail partition with quota support enabled, the checkquota proces alone will be intolerably long for the middle of the day. My suggestion: purchase a KVM. In my case, I've got a low-end 4-port KVM on my racks. There are about 12 machines there, but most are running Debian, so I rarely need a console connection on those. I leave windows machines and our voice mail server attached to ports 1-3. Port 4 I have as a roamer and attach to whichever Debian box I need at the moment (had a machine that tended to lock up and segfault for instance). By adding a KVM, not only have I eliminated the possibility of rebooting a Linux machine when I intended to log into an NT server, I have also largely emiminated having to rummage around the back side of the rack swapping cables. I hadn't realized that was a problem until one of our techs went through like a bull in a china shop and knocked the power cord loose from my email server. Now, since I've made the NT boxes all a pushbutton away, I'm the only one who ever needs to swap cables. Since I had to clean up the mess whenever the mail server got abruptly booted, I am much more careful than the people who caused the crashes.

There is no K5 cabal http://gestalt-system.sourceforge.net/ http://www.kuro5hin.org Part 1.2Type: application/pgp-signature You are on the right track. In half-duplex, the card basicly listens on its receive line while it's talking on the transmit line. Normally, in a non-switched, half-duplex, environment, only one card may transmit at any one time. If the card hears anyone else transmit during the time it's transmitting, it treats that as a collision. It will transmit a signal indicating a collision (which the hub will relay to all ports), and sleeps for a random time interval (the holdoff time is based on an interesting algorithm that makes the possible interval wider, depending on the number of collisions the card has seen). In a simple case of two network cards talking directly to each other (or a network card talking to a properly configured switch), both cards may transmit at once. Since the transmit and recieve pairs are seperate physical media, the transmission of one card won't interfere with the transmission of the other. To allow this, we put the card (and the ports on a switch) into full-duplex mode, which basicly means just go on talking if the card at the other end is talking too or ignore collisions. What can become an issue is whether the card and the switch properly autoconfigure, or recognise that they're attached in a configuration that will allow them to safely operate in full-duplex mode. As another consideration for the performace issues the original post referenced, many higher end cards have the ability to change how some transmit and receive buffers are allocated. They can chose how full the buffer can get before triggering an interrupt, some can shift the buffer sizes to favor transmission over reception, etc... --Rich -- _ Rich Puhek ETN Systems Inc. _

Re: FW: Sendmail
How are you trying to start sendmail? If you are just trying sendmail as root, you're not starting the daemon up to listen for incoming mail, you're invoking the sendmail program as if you want to create a message. Try (as root) /etc/init.d/sendmail start and see what you get. Sendmail is a bear to set up at first. It's a great MTA, very capable, but can be a bit intimidating to configure. If your needs on the box are fairly simple, you may want to consider using exim instead. As something else to consider: Do you need to receive mail on that box? For most of my machines, I have absolutely no need to receive email directly on the machine. The only machines I run sendmail on are those that are actual mail servers (those that are either receiving email for my domains or those that are relaying mail for my clients). The rest of my servers need to be able to send email (so that daemons can send error messages to me, and stuff like that). For all those servers, I run Exim setup to use a mail server as a smarthost. Most importantly, I remove exim from inetd.conf, so that they're never used to relay mail. --Rich Peter Donaldson wrote: I tried sendmailconfig but still i am having the same problem.

Re: (OT) Storage (8*IDE HDs) any experiences?
Dell Poweredge 2450 style servers is what you're looking for. They have two power supplies, each with its own power cord. Yes, it can run on one PS... the last one I set up ran that way on my desk since I only had one cord handy. Of course, you'll want to make damn sure the grounds are at the same potential, so doing funny tricks with where you plug them in could be a bad idea. Another nice thing about this (and probably all the machines Matthew's referring to) is that the motherboard doesn't need to support multiple supplies, nor do the hard drives, fans, tape drives, etc. I agree with Matthew in that there _is_ a reason to share the load, actually a few that I can think of. Let's say you have a pair of 300W supplies on a box that draws 250W at rest. Rather than let one supply crank along at 250W, let's let both supplies run at about 125W. That way, both supplies will run cooler (Depending on the supply design, the supply may actually have slightly lower efficiency at the lower load factor, but that's a trade off we can live with). Also consider what happens if the load was near the capacity of a single supply, and spiked over the capacity. If we were using the second supply as a backup to only be switched in if the primary failed, how would that be handled? --Rich Matthew Sackman wrote: On Fri, Apr 27, 2001 at 12:05:11PM -0500, Dimitri Maziuk wrote: On Thu, Apr 26, 2001 at 05:32:31PM -0700, Alvin Oga wrote: ... - even if you had 2 power supplies... - most motherboards only has one atx power connector True.

I imagine that's too hard and not worth the trouble anyway: what you usually want is redundancy, not load sharing. (I mean, if one PS dies, it will overload and kill the other one pretty fast. Not a good idea. And if each PS can handle the load alone, there's little point in sharing the load.) Every production server that I've seen that has 2 PSUs has both continuously running. At hopefully 50% capacity. There is no switch-over - if one goes then the other has to cope with both. Of course, the irony is that as they are both routed to the same power inlet, if the fuse in the plug goes then you're buggered anyway! :-) Matthew -- Matthew Sackman Nottingham, ENGLAND -- _ Rich Puhek ETN Systems Inc. _

(Sorry about the blank email... too much caffeene got me a twitchy trigger finger). Dimitri Maziuk wrote: In fact, there will be some point at which each individual PSU will run just as hot as if it handled all the load on its own (you can be sure your box will draw exactly that much load, thank you Mr Murphy). Hmmm, I'm doubtful that that's the case if our load is around 25% to 50% or something like that. That's based on almost a pure guess, but I recall UPS efficiency numbers of something like high 90% numbers for almost full load versus 85% or so at 50% load. Obviously, a very lightly loaded power supply will put out about as much heat regardless of whether it's running at 1% or 2% capacity, but I'm thinking that will diverge fairly quickly. Also, in most PS and case designs, the PS should have a negligable effect on the heat transfer of the box, given that its fan exhausts directly to the exterior of the case. If the case is ventilated through the power supply (as common in desktop PCs and low end servers), there will be a small change, depending on the temperature within the power supply case (been about 4-years since I decided 'Thermo and an ME degree weren't for me, so the ideas are fuzzy for me too). I'm not arguing that this is the case, I'm saying that this kind of argument can be twisted and turned any which way you like. Very true, which is why redundancy will be the main factor, not heat production. I had mid-80s AT PSUs. They'd still be working if I didn't have to move house and throw all that junk out. If a PSU lasts for 15 years, will 2 load-sharing PSUs last 30 years? Do I care? (Will I last 30 more years?) I know that CPU will maybe last 1/5th of that, disks maybe 1/3rd. So what is it I'm going to achieve by setting up load-balancing PSUs? Well, those mid-80s AT PSUs (in general, I mean) seem to have either been A) oversized for the AT PCs or B) just better quality than normal desktop-grade power supplies of today. (BTW: I recall hearing that Intel speced Pentium CPUs for a lifetime of 10 or 20 years in normal usage... used as a rationale for overclocking and the reduced lifespan it causes). No, I don't anticipate a linear relationship between load and lifespan, nor would I anticipate a linear relationship between load and heat disappated, heat dissapated and lifespan, etc... I would however, anticipate that keeping a power supply running somewhere under its full rated capacity will increase its lifespan to some extent. Also, in a load-balancing configuration, you eliminate the ... Also consider what happens if the load was near the capacity of a single supply, and spiked over the capacity. If we were using the second supply as a backup to only be switched in if the primary failed, how would that be handled? Well if you mean some piece of hardware suddently decides to draw $BIGNUM times its normal current, the PSU will die. Depending on the design, there's a circuit somewhere (eg. on the backplane) that does the appropriate magic and switches the second PSU on. Of course it'll die very soon too, unless the FPOH in question magically fixed itself in the meantime. I was thinking more like the combined load in the box was something like 95% of the rated capacity of the power supply, then spiked to 110% (like having a bunch of SCSI drives spin up). A decent power supply probably won't let the smoke out, but it probably won't give the best power either. A redundant load-sharing arrangement would have both supplies running at something like 42.5%, then spike to something like 55%. Granted, this is a bit of a stretch, but I've seen too many cases recently of servers in a simple consumer PC box that gradually got stuffed full of SCSI drives until a PS failed. Sometimes the magic fails -- I remember the look on my boss's face when he pulled a hot-swappable PSU out of a live swerver, and the box went down. Oops. (Only happened once; we later tried to reproduce the problem, quite unsuccessfully: PSUs switched over like a charm, every bloody time. Surprise, surprise.)

I like to wander through the computer books section and page through some of what catches my eye. Often I find that a book that looked real interesting is actually very shallow in its explanation. Other times I find that the book dives much further into the subject than I really care about. By loooking at the book itself, you'll see the scope of its coverage and its applicability to your needs. As for some other suggestions... You might want Programming PERL from O'Reilly and Assoc. There are a load of other books out there on PERL, but you'll probably find that the camel book will get you up and running in PERL rather quickly (assuming that's a desireable goal for you). If you're planning on administering your own machines at some point, and need to provide web or email services, the Apache and Sendmail books from O'Reilly are almost mandatory. Be forwarned that the Sendmail book will likely require $400 worth of reinforcing to your bookshelf. It has also been rumored to distort gravaty in the near vicinity, so you might confuse some of your collegues in the Physics department.

One of them will likely be much bigger than the others (probably /var). If so, cd to that directory, and repeat the above command. By repeating that sequence, you'll find the biggest problems.

Look into doing something like: tar -clzvf /home/somedir/My_backup.tar.gz /* The -l (el not one) option will keep tar from trying to move off to another filesystem.

As for safely fiddling with your kernel... you'll want to get familiar with how LILO works and where your kernel goodies are. The Debian kernel install tools help a lot, since they try to keep your last successful kernel around in case the new one fails to load. Basicly, you'll end up with two files in root (actually, they're usually symlinks to files located in /boot): vmlinuz and vmlinuz.old. Lilo will try to load up the vmlinuz image at boot. If that image fails, you can hold down shift (or was it spacebar?) as your machine restarts. You will be presented with a boot: prompt, which will allow you to chose a kernel image to load. It's been a long time since I've had to do this (been lucky with my kernel builds lately), but I believe all one needs to do is enter vmlinuz.old to load the old image. Don't worry about problems enabling SMP support... that's fairly simple (a checkbox in the kernel config). The other little details like device drivers will get you.
