Konsole and Wget safe?
 

If I were to run Wget in Konsole, and after using it, I leave Konsole open and unattended. But running as a user (not su). Would that still be dangerous?

I mean, I did open something in Konsole to connect to the outside and download something. After my downloads are done, would that opening still be open for the 2nd party or 3rd party to get into my computer and collect information, or do damage? Or will it only be closed, when I exit Konsole?

I don't see why wget and konsole would be any hazard. If your computer is firewalled properly (you can find out at ShieldsUp by grc.com) then it doesn't make a difference. wget is an HTTP client, not a server. It doesn't accept connections from outside. Konsole is neither a client nor a server (unless you count that it's an X client. but forget that) so that shouldn't be a problem. Even WHILE wget is running nothing is wrong. The only problem would be if you:
- ran a program that listened for and accepted incoming connections or commands
- AND that program either offers unwanted access to your computer
- OR has a bug (vulnerability) that can be exploited to get in to the computer.

...so unless I missed the point...

As far as I know wget is just a download mgr. It gets the file and quits. And a good download mgr at that.

If your worried about security study on how to set up your firewall.
