Hi.

There's two ways: either run 'df' or look at /proc/partitions.

You should be able to parse either in your program.

To add slightly to ilikejam's comment, this will display the free space amounts in standard measures

Code:

df -h

I missed the second part of your question: run 'netstat' to see the status of your ports. There's also files in /proc/net which you should look at (I'm not too familiar with their format).
