Debian file server to WinXP clients
Ok, I've hit a road block here. I'm trying to find the best way to serve up 3 to 12 gig files to an office network of Win XP machines. We have everything on a Gig E network but I can't seem to find a good file serving solution. Tried the windows server but had major fragmentation problems and a hard time keeping up with the problem. Switched to linux but Samba's performance seems to be sub par. (Maybe 5-10 meg/sec transfer rate) I know a lot of this may depend on the file system and hardware being used but what networked file systems has returned good through put on multi OS networks?

Re: Guarding against DoS
In our setup, our clients call us because we are their upstream. We block it at our routers, then call our providers asking them to block it at their upstream. There is no way a client can refuse traffic (at least in most setups I've seen) without it passing through their port. The only option would be to allow colocate clients to have access to your routers for putting blocks in. Chris G.

If a colo'ed box gets hit with 20 mbps of incoming traffic, even if it ignores it all, then we might have to pay $2200 that month. That is not good! How can we keep ourselves from getting high bandwidth bills in a colo environment? If we block the traffic at a router in our rack, we've already received it and it has been counted. Is the only solution to catch it quickly and get the ISP to block it upstream? thanks, micah -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?

System Hardware Tracking
Well it's finally hit the point where we have a few machines where we have no idea what's in them. As an ISP with several hundred machines, it's become quite the challenge to remember all of the hardware. Has anyone made/found/dreamed of a script that can be run on each machine to keep track of the hardware in that machine. I'm more than happy to write one using perl/mysql, but figured I would throw this out to the list and see if someone has found/written something they use. Oh, and for all of those saying, write it down as your build the machine. I wish that would work, we just have too many people dealing with these things and when a problem comes up, our concern is to fix the problem ASAP, not count our hardware. Thanks for any help/ideas.

RE: IDE Raid Controller concerns
Check out http://www.akiwa.com/news.asp and their rack mount cases. They have some new ones that are quite nice and the price is pretty good for what they include. I would call them for up todate pricing, but when I called it was very competitive. (I think the 12 bay without power supply was about $300 or $400, but that was a while ago. The other place to check is www.rackmountpro.com. Their new RM2008, RM3012, and RM4016 are priced at ($789, $899, $1300 with power supply). That's what I have found so far. A tower will be a lot cheaper then rack mount. One thing to look at is if you really need the hot swap drive caddies, if you don't it can save you a bundle of money just getting a standard case with space for 12 drives. Hope it helps Chris G.

IDE Raid Controller concerns
I've got a couple questions related to IDE raid that if I could get some feed back on, I would really appreciate it. A little bit ago, we suffered from a single drive (in software raid 5) causing data corruption and poluting the array before being ejected. This made almost all the data on the raid invalid and unusable. We knew that this was probably going to happen sooner or later, but I started wondering about hardware based raid cards, and if they would handle this any better. I'm looking at a raid to have a 12x120 gig 7200 RPM ide drive setup. 11 drives in the array, and the 12th drive as the spare. Controller wise we are looking at the 3Ware Escalade 7506-12 card, but I have never seen this card in action, and I have no idea how it might handle the above problem. If any of you have used this card, what have your thoughts been? What problems did you run into? Do you recommend a different card in the same price range ($400 to $600)? Thanks for any help you might be able to offer. Chris G. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
