Determine name of installed package
 
How does one determine the command name of an installed package?

For instance, after installing the below, I would have expected it to be nmap-ncat, but it is really ncat or nc.

Thanks

Code:

there is no such thing. I mean for example the base package contains a lot of commands. Others contain a toolset, and finally the creator of the package can give any name (s)he wants.

NotionCommotion 07-29-2017 09:51 AM
Thanks pan64. Gotcha. How can one tell what commands come with a package?

knudfl 07-29-2017 09:56 AM
Commands :

RPM package : $ rpm -ql <package-name> | grep bin

You can also look in the documentation for the package.

man nmap-ncat?

Nope

man pages available on the net, and that package also have a homepage.
https://linux.die.net/man/1/nc
https://nmap.org/ncat/
You can always google...

You risk opening a hole on your system fiddling around with programs you don't understand like netcat.

I think it might suffice to say not to use netcat over the public Internet.

It would suffice, I only told them why it's not a good idea.

Never, or not until the program is understood? Any specific vulnerabilities one should be on the lookout for? Thanks

I was referring to opening ports. Ports you might not be aware you're opening that someone could access and looking out for your best interest.

If I were you I would study docs thoroughly to become familiar with its many functions before using it.

In addition to the Users Guide I linked to, where they reference it as "your network Swiss Army knife", there are several articles online about its use. This is just one:
