Oh!! I passed with 90%

Worked like a charm, Anthony! Thank you kindly, Sir!

Hey @Daniel-Engelkes

Here's a great resource that explains each and also shows you how to set them.

Hope that helps.

Thanks Anthony!

Awesome tips @Andrew-Despres @David-Thompson Thanks!

@Kapil-Renninger,
This to me is the frustration with Linux things...It's great until things like this. :)

Hey @anton-witting great question! If you are looking for a good CentOS (RHEL-like) alternative, check out AlmaLinux: https://almalinux.org/

Hey @Nikhil-Kumar great question:
For RHEL-based systems such as AlmaLinux that you dnf you can use the following:

sudo dnf [options] autoremove package_name

Debian-based systems such as Ubuntu:

sudo apt purge package_name

Below is a screenshot of the man pages of the dnf and apt command for you to compare:
dnf autoremove

Ok, will do. Thanks Ronnie.

With the permission denied error, I ask if the admin credentials on the newcomputer the same as the admin credentials of your own computer. It appears as if you do not have the correct credentials being used on the new computer.

@Giovanni-Baldi said in Configuring Cache Server with Bind:

I have just discovered a strange behaviour. As soon i enable the vpn bind start to works.

This seems to point the fact the VPN configuration may have changed your DNS setting to what was configured for your VPN, is it configured to your Bind caching server or something else?

Is it possibile that my provider block some bind traffic?

I tested also a laptop where bind works only if i use my smartphone as hotspot but stop to work if i connect to my Vodafone Router .
:anguished_face:

This one also may point to the default DNS server of your hotspot rather than your Bind server.

Thanks so much Joshua! Great stuff!

@Matthew-Dudek,

Be careful with indentations as ldapadd may see whitespace as command or data as confusing.

So check your formatting against what you've seen in the episode.

Let me know if this helped.

@S-M-SHAER,

You can do a search for his name in our course section. He also mainly does the Apple and Linux categories in our course library.

Hey @Marco-Antonio-D-Imperio

So sorry to hear that you're having trouble with Proxychains. Could you post some screenshots illustrating the problem you're having and the steps you're taking to get there?

Thanks,
Daniel

@Victor-Rosa Thanks very much for posting the solution, I did look at this post and was stumped myself - I learned something! :)

@Derek-Sompong No worries!

How long ago was the A+ and the Net+? If that A+ is expired unfortunately taking Linux+ won't renew it - once they're expired they need to be re-earned. If it's still current though it renews it for anther 3 years :)

Compilation errors are almost always tied to version differences in the compiler or dependencies. I suspect your version of GCC is either older or newer than what John the Ripper is expecting. Check their documentation and see what their requirements are. Then you can compare that against whatever tooling you are using to make sure you have the required supporting software.

Rodrigo,

It looks like you set the default FACL, but didn't actually assign permissions to the directory. You didn't share the command you typed to assign the FACL, but I'm pretty sure I can guess it. I recreated your example by doing the following:

dpezet@Dons-Desktop:~$ sudo useradd toni dpezet@Dons-Desktop:~$ mkdir gtic dpezet@Dons-Desktop:~$ setfacl -d -m u:toni:rw ./gtic dpezet@Dons-Desktop:~$ getfacl gtic # file: gtic # owner: user # group: user user::rwx group::rwx other::r-x default:user::rwx default:user:toni:rw- default:group::rwx default:mask::rwx default:other::r-x

This sets the default for new files in the directory to give read and write access to Toni. However, it doesn't actually give Toni the ability to write a new file in the folder. For that, we need one more command.

dpezet@Dons-Desktop:~$ setfacl -m u:toni:rwx ./gtic dpezet@Dons-Desktop:~$ getfacl gtic # file: gtic # owner: user # group: user user::rwx user:toni:rwx group::rwx mask::rwx other::r-x default:user::rwx default:user:toni:rw- default:group::rwx default:mask::rwx default:other::r-x

Notice that I left off the -d argument so that I am assigning actual permissions. Now we can see that Toni has permission to write into the folder. I granted execute as well since that is required to navigate into and view a folder's contents. From here, we can test it out.

dpezet@Dons-Desktop:~$ cd gtic dpezet@Dons-Desktop:~/gtic$ su toni $ touch file.txt $ ls -la total 8 drwxrwxr-x+ 2 user user 4096 Sep 15 07:55 . drwxr-xr-x 18 user user 4096 Sep 15 07:53 .. -rw-rw-r--+ 1 toni toni 0 Sep 15 07:55 file.txt $
