The machines I have around here, I consider 1 hour to compile a kernel pretty good. Actually I'm in the process of migrating to newer hardware, but I haven't tested kernel compilation times.

Also you mentioned accessing your KVM with a web browser... can you enlarge a few details on that? Let me start by saying that I looked up your KVM and was really impressed by it. Yours is the Iogear, right? Not Iomega, I think. I was really impressed that yours is all current technology, switching DVI port as well as mic speakers, that it uses USB keyboard mouse. My current model is a Blackbox KV9408A, back then I was still using my Austin Hughes IP-802. Basically, both are 8-port KVM switches with a framegrabber and some embedded Linux built on the same board. So the switch part allows you to manage multiple servers, and the framegrabber part allows this to be viewed across the network using a VNC client. I don't KVM at my desktop, I only use my main desktop machine there. The KVM-IP resides in the server closet, and can switch between my otherwise-headless machines there. It works really well for me, because a lot of my work is (or has been, at least) working on Windows PCs for small offices and home users. So if I bring in one of their PCs to recover data off it, run chkdisk or reinstall Windows, I just shove it in the closet and connect remotely. I don't have to cross the room or twist around in my seat to view the machine I'm working on, it just appears as a large window on the screen of one of the monitors of my desktop PC. I think this is *really* cool technology. There's something about it that appeals to me that I rate it on the same level of killer app as email and ssh. I practically fetishise it. These IP-KVMs cost c £1000 new, but you can pick them up on eBay for a song. I paid £100 for the Blackbox and I think c £120 for the Austin Hughes. The Blackbox is a little newer, I think, and initially more impressive to use, but overall the features of the two are about even. The web-interface of the Austin H looks a little dated now (it's a 2003 model), but it has the nifty programmable GUI buttons which I mentioned in the previous thread - with them you can create single-button shortcuts for any keyboard macro, and it also has a full on-screen keyboard for occasional use. I find the lack of that a real shortcoming in the Blackbox - this week I was unable to change some BIOS settings remotely because my MacBook's keyboard has no page-up / page-down keys. However the Blackbox just wins the comparison by a nose because it allows you to use any standard VNC client to view the servers - the Austin H requires you to use a browser-launched Java viewer. I could spend hours writing a comparison between the two products, because clearly I'm a fanboi for this technology. The two models do the same job, but it's interesting to observe that they have a bunch of implementation differences, and these have a range of more or less subtle benefits and annoyances. The market for these devices is fairly niche, I guess - it's impossible to find reviews of them before buying, and hard to learn anything at all about specific models, beyond manufacturers' brochures. A manual doesn't really give you much of an impression of how it is to actually use a particular KVM-IP. I imagine these are sold primarily to datacentres and the enterprise, companies who are buying 10 or 100 at a time, that they are serenaded by salesmen, and that the admins get to try a demo model, perhaps several, before buying them. I wouldn't be surprised if Alan has a few KVM-IPs, or can access his London / Paris / New York / Tokyo servers using them; I would be *extremely* interested to know what models he uses and what he thinks of them. The retail price is certainly prohibitive unless you've got a pressing business need for a KVM-IP, but as an enthusiast I can easily justify them secondhand. For me, bringing customer's PCs home to work on, they have been *so* useful. I continue to watch eBay for new listings - the only way to compare a new unit with my current one is to try it, and I don't think I'll lose anything on the deal if I manage to snipe an auction and then have a little patience in selling the unwanted unit locally or as a buy-it-now listing. Dell servers feature a similar technology which they call DRAC, which is a single embedded card per-server and which is not cheap. But it additionally allows you to power the server on and off and also to mount a .iso image in a virtual CD-ROM device across the network. So you can reconfigure the BIOS and hardware RAID array, then boot the server from this virtual CD drive and reinstall the o/s across the internet without any need for anyone to physically touch the machine. If the installation - or a kernel upgrade or anything else - goes wrong then you can intervene remotely and boot from a system rescue CD or whatever. I've used DRAC4 (early

Paul Hartman paul.hartman+gentoo at gmail.com writes: I bought this router the other day. I notice something that is a little weird. It seems like more of the computer and electronics problems I have (or that people bring to me) are related to power supply failures than any other reason. Shot in the dark: Make sure the router is on a UPS. Often you do not have power failures, but power glitches such as low voltage, particularly if the temperature has spiked cold in your area. Of if the local power companies is a slacker, like most of them are. Some areas are frequently swung from one substation to another substation, as the power grid managers try to minimize the operational costs and balance the distribution network. This sort of activity will kill UPS and batteries, prematurely. All UPS need to be tested to ensure the batteries are good every few months. If you can wire in addition jel-cel batteries in parallel so as to extend capacity and ease the drain-charge cycles on your UPS equipment. Best thing to do, is hook up a 100 watt (150) incadescent bulb and fixture and just pull the power cord. If the light flickers or goes brown or out too soon, your UPS may need either a new battery or if your UPS power circuitry is of poor quality or old, just replace the UPS. Power quality is a big problem, the world over and often the detection requires subtle interrogation, or a purchase to fix it. A Leroy fix is to plug a smaller capacity UPS into a larger UPS that is connected to the wall outlet, to prevent voltages sags due to old or poor quality electronics of the UPS(es). If you need batteries, I know of a good (cheap) supplier for Lead_acid batteries, in the US. so just drop me a line. Another idea, find out what voltage (DC?) your router uses, if it has an external power supply; it will be marked on the power supply. If you are lucky it uses 12VDC or 5-6 VDC and you can splice in Jel-Cell batteries of the appropriate voltage, for extra energy storage or to limit voltage sag. Just some random ideas and watch out for neighbors running too many christmas lights or a welder in the neighborhood. Power quality issues usually magnify during periods of peak demand. hth, James

[gentoo-user] SIMH on AMD64
Hi, I know, the SIMH-packages are masked The only question I have is: Does SIMH simply does not run on AMD64 (or is it my fault, that trying to laod an old UnixV6 tape and booting resulting in a endless process eating up 100% of one core of my CPU...?) Best regards, mcc

James wrote: Paul Hartmanpaul.hartman+gentooat gmail.com writes: I bought this router the other day. I notice something that is a little weird. It seems like more of the computer and electronics problems I have (or that people bring to me) are related to power supply failures than any other reason. Shot in the dark: Make sure the router is on a UPS. Often you do not have power failures, but power glitches such as low voltage, particularly if the temperature has spiked cold in your area. Of if the local power companies is a slacker, like most of them are. Some areas are frequently swung from one substation to another substation, as the power grid managers try to minimize the operational costs and balance the distribution network. This sort of activity will kill UPS and batteries, prematurely. All UPS need to be tested to ensure the batteries are good every few months. If you can wire in addition jel-cel batteries in parallel so as to extend capacity and ease the drain-charge cycles on your UPS equipment. Best thing to do, is hook up a 100 watt (150) incadescent bulb and fixture and just pull the power cord. If the light flickers or goes brown or out too soon, your UPS may need either a new battery or if your UPS power circuitry is of poor quality or old, just replace the UPS. Power quality is a big problem, the world over and often the detection requires subtle interrogation, or a purchase to fix it. A Leroy fix is to plug a smaller capacity UPS into a larger UPS that is connected to the wall outlet, to prevent voltages sags due to old or poor quality electronics of the UPS(es). If you need batteries, I know of a good (cheap) supplier for Lead_acid batteries, in the US. so just drop me a line. Another idea, find out what voltage (DC?) your router uses, if it has an external power supply; it will be marked on the power supply. If you are lucky it uses 12VDC or 5-6 VDC and you can splice in Jel-Cell batteries of the appropriate voltage, for extra energy storage or to limit voltage sag. Just some random ideas and watch out for neighbors running too many christmas lights or a welder in the neighborhood. Power quality issues usually magnify during periods of peak demand. hth, James I have it plugged up to the same UPS my puter uses. I changed the battery about a year ago and it is plenty large enough. It runs at about 40% load. I doubt it is a power issue. Dale :-) :-)

I installed the Gentoo pkg 'dhcpcd' 'dhcpcd eth0' gets the I/net : clearly, this is a big step forward by ISPs since 2001 ! I can also get through this way using Mandriva's wired connection. It still doesn't explain why Mandriva's pppoe works, but not Gentoo's, but that's now hopefully moot, if nothing goes wrong again. I don't bother with pppoe because the router-modem should give you a generic ethernet interface with a static IP address. I don't bother with dhcp either.
