Flagged Answer: https://askubuntu.com/a/154482/10616
I flagged this answer as "Not an Answer" with the reasoning: "Not an Answer since the OP explicitly stated the command initially (so repeating the command to use is not an answer in this case)" because the OP of the original question explicitly stated that was the command they already used. Therefore, suggesting that they may have mistyped the command, or suggesting that they should run that command is not a valid answer.
However, @jrg states that it "may be useful to people in the future" in the decline reason. I challenge any moderator (or any other user) to prove this, given that the OP already said they were using the
pppoeconf command in their question, which means generally that they were not misspelling the command, thereby making the answer that was flagged invalid.
