    Hiya DM...


    Read here http://wiki.synchro.net/config:sbbs.ini#global about LoginAttemptTempBanTheshhold. Yours is set to 20, so it should take 20 unique failed login attempts to trigger a temp-ban of an IP, unless
    that user tried one of the names in your name.can file.

    The user in question, IB Joe, has logged in numerous times without issue. Over the past 2 months there have been others who've said the same thing has happened, log in and use the wrong password on the first login and poof... they're history. I have set the above to 20 so I'll not have this issue. His username is not in the name.can file either.

    Also, you terminal server log output will have more details about the cause of the ban (not just "Blocked IP").

    Here is the log output..

    6/4 03:38:25p 1488 Telnet connection accepted from: xxx.x.xxx.xx port 1411
    6/4 03:38:25p 1488 Hostname: S0106bc4dfb234923.ed.xxxxxxx.net

    6/4 03:38:43p Node 1 (0003) Ib Joe FAILED Password attempt
    6/4 03:38:43p Node 1 !Failed login with blocked user name: Ib Joe

    I checked the name.can and 'IB Joe' isn't in there. There is an entry for the letter 'i' so is that causing an issue being his login name begins with the letter I?

    Thanks...

    On 2017 Jun 04 18:46:00, you wrote to Digital Man:

    Where does it store Blocked IP addresses other than the CAN files?

    in memory... there was recent but brief discussion about this... maybe
    as far back as four or five months i think?

    Quite possible but unfortunately, when the problem isn't your own, attention span is minimal. :/

    I checked the name.can and 'IB Joe' isn't in there. There is an entry for the letter 'i' so is that causing an issue being his login name begins with the letter I?

    Not unless the entry is actually "i~", as that would block all login
    names that begin with the letter 'I'.

    Nope, not there...

    Something in your name.can is matching the string "Ib Joe", so
    perhaps just posting the contents of your name.can will help us to identify the problem.

    Here ya go...

    !!huawei

    ^ There's your problem.

    A '!' as the first char on the line negates the matching logic. So your name.can says that any name is *not* "!hauwei" is trash.

    Ahhh.... ok...

    You could do huawei~ instead. Then any name containing "huawei" will be considered trash/bad.

    Done....

    BBS aliases already have to begin with an alphabetic character, so any alias starting with a symbol or number would not be allowed (e.g. when creating a new user account).

    name.can edited and board tested... just like the doctor ordered..

    Thanks again DM...
