LAN users' IP

[Gediminas2]

Hello everyone,
is there a program to scan the LAN and see what IP's are currently connected?
Using ping for 255*255 addresses doesn't seem efficient.

package name: nast

Available in Adept Manager

packet sniffer and lan analyzer

Can sniff in normal mode or in promiscuous mode the packets on a network interface and log it. It dumps the headers of packets and the payload in ascii or ascii-hex format. You can apply a filter. The sniffed data can be saved in a separated file.

As analyzer tool, it has many features like: * Build LAN hosts list * Follow a TCP-DATA stream * Find LAN internet gateways * Discover promiscuous nodes * Reset an established connection * Perform a single half-open portscanner * Perform a multi half-open portscanner * Find link type (hub or switch) * Catch daemon banner of LAN nodes * Control arp answers to discover possible arp-spoofings * Byte counting with an optional filter * Write reports logging

It also provides a ncurses menu

Here's a few commands I had stashed, but not sure if any will help you with this:
FIRST: K-Menu > Run,
type xterm
in the text field, Enter. Now you can run these commands:

route Print routing tables and interfaces in use.
dhclient Request an IP address when using DHCP: (in the result line, DHCPACK = IP address of your router)
ping -c 10 192.168.1.1
where in place of 192.168.1.1, put your IP address of your router from the line DHCPACK from the command dhclient. This will tell you if you have a two-way communication with your router.
ping -c 5 google.com Check if you can send test packets across the Internet.
cat /etc/resolv.conf Check which host will resolve domain names (should be IP address of your router)
