Still not successful yet and I upgraded my nmap version. Using the following syntax to attempt a single-threaded attempt: nmap -p 23 --max-parallelism 1 --script telnet-brute --script-args brute.passonly=true,passdb=testPasswords.txt <ip addy>
--max-parallelism is controlling the scanner itself, not the brute-forcing worker threads. Add the following script arguments instead: brute.threads=1 brute.start=1
PORT STATE SERVICE 23/tcp open telnet | telnet-brute: | Accounts: No valid accounts found |_ Statistics: Performed 1 guesses in 164 seconds, average tps: 0.0
Something is seriously not working here. A single guess should not take almost three minutes.
Problem is I know the lone password in the testPasswords.txt file is the valid password. Checking the brute NSE library page for more ideas, but open to any.
This is hard to diagnose without more data. Can you provide a pcap/pcapng of a single nmap run against the target together with nmap output, while making sure that you are using the thread settings from above and enabling debug logging with -ddd? nmap -ddd -n -Pn -p23 --script telnet-brute --script-args brute.passonly=true,brute.threads=1,brute.start=1,passdb=testPasswords.txt <ip addy> Feel free to send the two unedited files to me privately.
