Is there a way to list available ports?

Or contrapositively, is there a way to list all the used ports?

SuSe. Kernel 2.4.something.(Is there also a simple way to determine the kernel version?). Thx.

I'll stick to the hidden contraposite

Used ports:

Code:

netstat -a

or

Code:

lsof -i 4

Kernel release:

Code:

uname -r

try this for the kernal name:

Code:

uname -r

type man uname to learn the other switches to display other info.

as for to find the ports. Im using Fedora Core 3 and in the start > system tools menu there is network tools. It is a gui for several common network tools. I used the port scan in that scanning 127.0.0.1 to see my ports but can't figure out the name of the command line utility that it is a frontend for.

edit: knew that was going to happen. While i was looking for what cmd line program it was someone else posted before me. lol

thx gents. netstat -a worked well enough. I didn't care for the ouput so I piped it through grep to search for any used ports matching '611' (netstat -a|grep 611).

uname -r tells me the kernel: 2.4.19-3suse-SMP

that lsof sure gives a ton of info.

Thx a bunch.
