Using your favorite text editor, create a file, and add a few common usernames: rootĪnd do the same thing for the passwords: password In a real engagement, we'd want to use files with much larger data sets, but for demonstration purposes, we'll keep these short to speed up the whole process. Next, let's create two text files, one for usernames and one for passwords. Nmap done: 1 IP address (1 host up) scanned in 0.82 seconds We will be using Metasploitable 2 as the target and Kali Linux as the attacking machine. It seems really strange to have this be the case.Before we begin, let's run a simple Nmap scan on our target to make sure the FTP service is present. Looking for some knowledge on this topic. What makes WingFTP give out a new SSH key that's less strong in this case (1024) than what was sent/requested in the connection that's attempted by WinSCP? For example, could a firewall rule actually be suppressing the higher encryption, which then forces WingFTP to issue a less strong key instead.which then produces the "Host key does not match configured key fingerprint" error? So specifically, under what circumstances would a connection made to WingFTP that explicitly specifies the key to use, would WingFTP reply and say that the key is now different? This makes no sense, given that the device we're connecting TO the WingFTP server.always comes in on the exact same port and IP. What would cause WingFTP to return an ssh-rsa 1024 key, when what's being sent to connect to WingFTP, is a ssh-rsa 2048 key? This makes no sense. ė:05:57 AM Host key fingerprint is ssh-rsa 1024 ADifferentFTPKey ė:05:57 AM Host key does not match configured key fingerprint ssh-rsa 2048 OurWingFTPKey ė:05:57 AM Host key does not match cached key However, everyday when the script runs.WinSCP will produce the following error in the Log File: ![]() Code: Select all open -hostkey="ssh-rsa 2048 OurWingFTPKey"
