I've forgotten my PPoE password, but it is in my config.bin file. Is there a tool I can use to read that file?
No, the file is encrypted. Check here for instructions on how to decode it: http://the.taoofmac.com/space/Linksys/Configuration
If all you need is your PPPoE password, then it would seem a lot easier to simply call your ISP and ask them for it. Although I admit decoding config files is pretty cool, it might be a little overkill for this situation.
