Re: copying a 12GB file
I very well may be a problem with NFS itself, and I'd like to know what it is if you ever figure out the problem. Have you tried directly connecting together the two machines that are having problems? Have you done tcpdumps on the links that the machines exist on? Are you getting any collisions on the network links? What network cards do you have in the machines that you are dealing with?

Re: copying a 12GB file
I've had this same problems here with a machine that's on a segmented network here. Where I would get these I/O Errors when I use nfs in async mode. After a lot of investigation it turned out to be a interaction problem between a very large and old cisco switch and a router(aslo cisco). It turned out that my cisco switch was doing all sorts of things that either it shouldn't have been or, didn't need to do. To test to see if this is a problem in your case, try plugging a cable directly between your two machines(x-over of course). Then try a async transfer. If that still fails, try getting better gig-e cards. I recommend the intel built gig-e cards.

Re: Open ports in Debian
port 111 will be used by rpc processes like NIS and NFS. port 113 is identd, used to identify the "owner" of a connection. port 903... I'm not sure. If you box is up on the world. I would suggest making a iptables(or equivilent) script that will block all but the wanted ports. IE, having these ports open can be harmfull. I leave these things open on my internal network, but on my public webserver I only open what I need and deny everything else.

Re: IDE hdd faster than sata? How come?
Also you have to consider that many of the first and some of the second generation SATA drives are simply pata drives with bridge chips. The bridge chips reduce max bandwidth. You are also not going to be able to use things like commang queueing that SATA makes avalible with these dirves. most of the ATA133 drives were only as fast as the better ATA100 drives. It seems like one of the main reasons for the speed increases is for marketing purposes.

Probably. It depends on what type of wireless connection you have. What kind of modem. If your internet comes to you down a ethernet cable, you probably won't have problems. If it's through a pcmcia card, you can google for linux and the card to see if anybody has had success with it. If it's down a usb cable your in a problem territory. Most ofter your only going to be able to use that device if someone has taken the time to write drivers for linux. Again, google for linux and the usb device for more info.

Re: How to install under a SATA disk?
I'd suggest buying, or borrowing a usb cdrom to install with. Most motherboards support usb-cdrom booting now.
