    Hi there

    I set up my server a couple of months ago and used the pure-ftp with mysql how to on the site and my server has been a happy camper until about 2 weeks ago, 2 events occurred not sure which one borked the server though.

    The first was an update via apt-get upgrade, the second was someone trying to brute force the server, looked like a zombie script. So I turned off the server as it was not needed for a day or so then fired it up again

    Once it was up I noticed the following. When I try and connect (I use filezilla as a client) i get the following

    Code:
    Status:	Connecting to <server> ...
    Status:	Connected with <server>. Waiting for welcome message...
    Response:	220---------- Welcome to Pure-FTPd ----------
    Response:	220-You are user number 1 of 50 allowed.
    Response:	220-Local time is now 17:16. Server port: 21.
    Response:	220-IPv6 connections are also welcome on this server.
    Response:	220 You will be disconnected after 15 minutes of inactivity.
    Command:	USER <user>
    Response:	331 User <user> OK. Password required
    Command:	PASS ********
    Response:	230-User <user>has group access to:  ftpgroup

    Response:	211 End.

    Command:	PASV
    Response:	227 Entering Passive Mode (88,198,5,149,192,40)
    Command:	LIST
    Error:	Transfer channel can't be opened. Reason: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.
    Error:	Could not retrieve directory listing
    Command:	REST 0
    Error:	Timeout detected!
    Status:	Waiting to retry... (5 retries left)
    
    I thought it may initially be an issue with my user but it seems to affect all users, the other thing I did notice is that the virtual ftp user has no write access on their directory, and I have to manually chmod/chown the directory this however has been around since day 1 of my install.

    The actual ftp user is set to "No login allowed" in webmin and their home directory is set to /bin/null, and the virtual ftp users UID & GID are correct, I am at a bit of a loss here, any tips?

    Not sure what port 1524 is but the machine is behaving.

    So what suggestions then a fresh install or move to something like vsftp? Multiple accounts are not mission critical on my server

    Do you use Portsentry? If so, I'm sure the message is caused by Portsentry.

    If it isn't too much hassle, I'd reinstall the system. And remember: never touch a running system. ;) (Or at least have a backup before you do.)

    yes I do use portsentry

    As tempting as a reinstall is its a bit of a bugger to do considering I have no failover system. Thanks for the advice anyways :)
