Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

i have three hosts debian_a,debian_b and mac_c. debian_a is a server running ssh daemon, debian_b and mac_c want to scp to it. debian_a and debian_b are running linux, debian testing. mac_c is running mac os x 10.2.8. the hosts are all in the same subnet. (which is 'virtual' - that's what i was told, i'm not sure what it means. fact is, that the hosts are in quite different parts of the building, server room and offices, but (virtually?) grouped together in subnets.)
scp works the way i want, but the transfer rate from mac_c to debian_a is ridiculous (ca. 20 KB/s and frequent stalls, as opposed to the transferrate of ca. 1 MB from debian_b to debian_a). the strange thing is, that the transfer rate from mac_c to debian_b is quite the same as from debian_b to debian_a. i therefore think that it's got something to do with the network, there must be some obstacle between mac_c and debian_a.
since i'm not at all savvy about these network things, i'd really appreciate if someone has pointers for me as to how to troubleshoot this situation, i'm not quite sure where to start.
i've tried with scp -v from both debian_b and mac_c, but i didn't find any relevant differences.
as i pointed out, the hosts are all in the same subnet and have direct access to each other, no gateways in between. but the subnet is virtual, i.e. they actually are behind different routers and the like, but this is (or should be) invisible to the hosts. i'm afraid i don't know much about this, since it's not administered by me.
the only thing i know is that mac_c is behind a switch, client debian_b is not. but another machine behind the same switch gets good transfer rates to the server debian_a.
do you suppose the problem is related mainly to the network?
