John Baptist's questions

I'm new at this: I'm trying to set up a ssh server on my personal computer with openSSH. So far, I was able to connect to my server through my computer and also from a different computer in the same network.

However, I am unable to allow access to different user. I have to put the personal computer user (Mark) in order to access it ([email protected]). When I try with "test" it says "Permission denied".

Here are the lines I added in the sshd_config file:

PasswordAuthentication yes
AllowUsers    test    Mark

I did try to restart the ssh server after the changes,still not working.

Is there something I forgot to do?

Thank you very much!

So there's something that's bugging me on Ubuntu, never figured out how to fix it.

On Windows 10, if I have multiple files in a folder and I type the first letters, it just automatically selects the folder starting with the same few letters.

On Ubuntu, it lists matching items, like this:

As you can see, it does a search of "goo" instead of highlighting the google-chrome folder without searching.

Is there any way to fix this?

Thank you!

So it's just a simple question because I really don't like the aesthetic of it (even though the software is working just fine), I installed Bluej for java and added it to my favorites on the left of the screen but instead of seeing the logo of Bluej, a blue jay, I get a grey box with a red circle inside (so like a forbidden sign). It also shows that when I just open Bluej and it's not in my favorites.

Is there a way to fix this?

Thank you very much

I just want to know how I can find, in a folder, the files that have no group user permission (no read/write/execute) at all, using the terminal.

I want to count the number of different name in a text file of this presentation:

2008 girl Avah
2009 girl Avah
2008 girl Carleigh
2011 girl Kenley
2012 boy Joseph
2013 boy Joseph
2014 boy Isaac
2014 boy Brandon

So basically I want to skip the duplicate and have as an answer 6. I tried with awk to access only the third column but I can't get it to print the number of lines.
