How would i check for following?
1)open ports in my linux machine.
2)Hard disk read speed.
3)Hard disk write speed.
nmap localhost
netstat --listening
..can give you open ports
For hard disk info, there are some tests you can do with hdparm command to give you an indication. But use this with care with correct options...

output of netstat is categorized in two part.
1)Active Internet connections (only servers)
2)Active UNIX domain sockets (only servers)
Can u please give me a brief information about them?
