I think I didn't make myself clear...
The thing I really want to know where is the data for "resolving" port names.
Like: where lsof will go to translate "80" into "www", "22" into "ssh", and so on...
I've checked the lsof source, but didn manage to find where it pulls this info from...
Here does linux generally keeps this kind of info?
I know is kept in a file somewhere...!
Where is located in Debian?
Like when you type lsof , lspci , lsusb and it shows all that info about the part / manufacturer
Especially lsof that "resolve" port service names (like ssh ... www)
Ports and hardware parts names? service pci usb lsof lspci lsusb
