codes to/from FTP clients. Some codes represent errors, most others simply communicate the status of the

connection. Below are brief explanations for the most common status and error codes. When determining a course of action, review the entire log; some codes are informational only,

others indicate that you have entered the wrong information, and others indicate what the information is that you need to provide before continuing. For troubleshooting CuteFTP connection problems, also refer to Troubleshooting CuteFTP Connection Problems. The table below is provided so that you have some idea whether you can solve the issue on your own (e.g., ftp return codes mainframe code 331=you need to provide a password) or you need to call your ISP for assistance (e.g., code 426=you are unable to connect to the remote server). These codes are used by most FTP servers/clients. NOTE: The information below is only offered as a courtesy to assist you in telling your Internet Service Provider what the error is so that they can help solve your issue. For example, if you get a code 426, the transfer was aborted and the connection closed. The solution to this error is to "try logging back in; contact your hosting provider to check if you need to increase your hosting account; try disabling the firewall on your PC to see if that solves the problem. If not, contact your hosting provider or ISP." The list below contains standard FTP codes. Numbers outside this list are proprietary to the Server or Client that you are using.

in mind the intended use of the logged data, the volume of data being logged, any post-processing that may need to be done, etc. Log files are more useful when they contain a complete record of server activity. ftp command codes It is often easier to simply post-process the log files to remove requests that ftp error 426 you do not want to consider. Security Warning Anyone who can write to the directory where ProFTPD is writing a ftp error 451 log file can almost certainly gain access to the UID that the server is started under, which is normally root. Do not give people write access to the directory where the logs are stored without https://kb.globalscape.com/KnowledgebaseArticle10142.aspx being aware of the consequences: if the logs directory is writable (by a non-root user), someone could replace a log file with a symlink to some other system file, and then root might overwrite that file with arbitrary data. If the log files themselves are writable (by a non-root user), then someone may be able to overwrite the log itself with bogus data. When opening log files, proftpd will http://www.proftpd.org/docs/howto/Logging.html by default log a warning if the file being opened for logging is in a directory that does not exist, or is world-writable. The log file will not be written in world-writable directories; there are no exceptions. (If you have configured log files in your proftpd.conf that are not appearing, check for the warnings about world-writable directories.) The proftpd process will also, by default, log a warning if the file given is a symlink; this symlink check can be configured via the AllowLogSymlinks directive. In addition, log files may contain information supplied directly by the client, without escaping. Therefore, it is possible for malicious clients to insert control-characters in the log files, so care must be taken in dealing with raw logs. Unix syslog Logging By default, proftpd will log via syslog(3), using the daemon facility (auth for some logging), at various levels: err, notice, warn, info, and debug (debugging is done at this syslog level). The location of the server's log files in this case is determined by your /etc/syslog.conf configuration. You can fine-tune your proftpd's syslog-based logging via the SyslogFacility and SyslogLevel directives. See the log level documentation for more details on these settings.

I used the default Ubuntu/Apache box. Then I installed ProFTPd (following the Digital Ocean tutorial). Everything worked well; I SFTP accessed it with Filezilla (via the not recommended use the root account as I have nothing up yet really; I'm just testing right now). Then I added a new user account and was attempting to log in with that with the insecure plain ftp protocol. It returned 530 (on the password). So I restarted ProFTPd a few times and confirmed I'd done everything as directed in the tutorial. So what can I do to enable access there? Further Note: SFTP access isn't actually interfacing with ProFTPd since it works when the service is stopped. I'm basically a Ubuntu neophyte - but very experienced with Windows and windows batch files, python, configuration files, Apache set up etc. so I can easily follow any directions. little log snippet: 2014-08-31 11:08:12,495 BriarMoonDesign proftpd[9347] BriarMoonDesign
