Synced
Task 1: What is the default port for rsync?
Running an nmap scan of the IP shows that rsync is running on port 873 which is the answer to this question.
Task 2: How many TCP ports are open on the remote host?
The nmap scan from before also only shows one tcp port open.
Task 3: What is the protocol version used by rsync on the remote machine?
Run a version nmap scan which gives you a version 31 for rsync.
Task 4: What is the most common command name on Linux to interact with rsync?
I guessed rsync which was right but a quick google search also gives you the answer.
Task 5: What credentials do you have to pass to rsync in order to use anonymous authentication? anonymous:anonymous, anonymous, None, rsync:rsync
I took a guess and it was "None"
Task 6: What is the option to only list shares and files on rsync? (No need to include the leading -- characters)
I browsed the options menu for rsync and found that the option is "list-only".
Submit the Flag:
Utilizing the following commands to see what shares are available:
rsync --list-only [IP]::
This shows two shares. Let's take a look at the public shares with this command:
rsync --list-only [IP]::public
There is a flag file available. Use the following command to download the file:
rsync [IP]::public/flag.txt flag.txtThis should download to the file to your current working directory.
cat the file to show the flag as: 72eaf5344ebb84908ae543a719830519
