Hi, I have to install a small network in a school in a nearby village. The network will be Linux-only, one server and fifteen desktops. Here's the idea. 1) Authentication should be managed centrally on the server. 2) User home directories should also be on the server. 3) Users should all have disk quotas, something like 1 GB per user. 4) Some shared directories should be read/write for

Hi, quite often I find myself using commands like $ ssh foo nc bar 12345 to connect to another host behind a firewall, and I also have a lot of these commands in my ssh config file.

On my CentOS 5 box, in a C++ program that does much arithmetic, including numerous matrix multiplications, I have a situation in in which the result depends on the nature of nearby I/O. Thus, with all arithmetic done with type double, and where values are mostly in the range [-1.0e0,+1.0e0] or nearby, I do: cerr << "some stuff" << endl; mat3 = matmult(mat1,mat2); I
