Is there a software alternative to NetScanner (which runs on the Windows platform)?
You can try zenmap, which is the graphical interface to the command-line
sudo apt-get install zenmap
It's pretty easy to use. It won't do mapped drive mounting though, although it's got other very useful features like OS detection and non-ping based scans.
Sectools.org has some lists of other software that might be of interest (for various platforms, but of course including Linux).
There are also some more specialized scanning tools in the Ubuntu repositories, such as doscan, pnscan, and hping3 .
nmap is probably the most widely used, though.
AngryIP is a good scanner. It's primarily used through the gui, but has cli options too:
jake@daedalus:/$ ipscan --help Unknown option: - Pass the following arguments: [options] <feeder> <exporter> Where <feeder> is one of: -f:range <Start IP> <End IP> -f:random <Base IP> <IP Mask> <Count> -f:file <File> <exporter> is one of: -o filename.txt Text file (txt) -o filename.csv Comma-separated file (csv) -o filename.xml XML file (xml) -o filename.lst IP:Port list (lst) And possible [options] are (grouping allowed): -s start scanning automatically -q quit after exporting the results -a append to the file, do not overwrite
