Use finger to identify users logged in to a remote host.
- [Voiceover] Finger is an older utility which was…used for enumeration.…It may still be available on some systems…and if it is then it's an easy way…of enumerating users.…I've installed the Finger demon on my Ubuntu host…so let's take a look at what it gives me.…It's basic use is to check on details…of a specific user.…Let's look at the user Malcolm.…This provides the home directory…for the user Malcolm, the username,…the login shell, details of the user login time,…and information about malen plans.…
I can use Finger to look at all logged in users…on a host.…I do this by emitting the username.…Malcolm and Harvey are logged in…and we can see their details.…We can also use Finger to get information about…users not currently active if we know their user id.…Finger is legacy and often not used.…But if it's detected on port 79…it can be quite useful.…
