of computers of all those which connect to my computer by any source ssd,telnet.

You can probably get most of the info that you are looking for with nmap.

The connection times are also logged in the syslog. To get the hardware address, just run "arp -n" while the computer is connected.

I just want to keep a log the computers connected.
arp will give just connected machines only.

it is just like that when a visitor visits the site and counter keeps the log of ip , time spent,user agent,operating system
like this I want to implement this on lan with computers

I think you shouldn't care too much about the hardware address, though. In different network configurations, it's often far from reliable, and often even impossible, to get the hardware address.
