Hello everyone! I have a question. I do not know how to install nmap and all of its dependencies on Ubuntu. As far as I know, we can use the command
"# pkgutil i nmap nmap" to install nmap and all of its dependencies on Solaris, however this command is not available on Ubuntu. So I tried to use "sudo apt-get install nmap". It seems that nmap and all of its dependencies have not been installed successfully. Because I did not get lots of lines printing out and periodically asking me to enter all or y. I did not see lots of lines that start with Fetching.... Also I tried to scan a specific machine for open ports. (e.g. # nmap –v 18.104.22.168 > filename2 2> errorfilename &). I have re-directed output, both standard out and standard error, to files and executed the program in the background. When I check the two files, I found that they were empty. I do not know why. After I input the command "sudo apt-get install nmap", the following lines were displayed on the terminal. I am a beginner of learning Linux. I am looking forward to your reply. Thank you very much!
