Now =suddenly today all authentication failed (email, admin, ftp). I was able t=o log in through SSH and run dbrecover. That fixed the problem briefly, bu=t then it failed again. I tried rebooting the server but same problem. It =also seemed that many of the times I ran dbrecover it did not solve the pro=blem, even temporarily.Now it is the evening and the problem seems to have gone away for now.My initial thought is that it was a dictionary attack causing this problem =as I've run into this before. However, while I could see obvious hacking a=ttempts using email login attempts in the secure log, they did not seem to =be very numerous. (I could be wrong as I don't know exactly how to determin=e the number). In any case, during the several hours when this problem occ=urred, there didn't seem to be a heavy load on the server as I had experien=ced in the past with such attacks.I know that other people have experienced a similar problem. I have read B=rian's instructions for converting the passwords to a flat file. I'm not s=ure if that will resolve the problem I'm experiencing, or there is somethin=g else going on. Just curious if there is anything else I should be looking= for._________________________________________________________________You keep typing, we keep giving.
