550 No connections allowed from your IP

遇到FTP连接错误时,通过重启FTP服务解决了问题。问题涉及FTP服务器为FileZillaServer0.9.48beta,操作系统为Windows2008R2x64SP1,客户端为FileZilla3.9.06。错误代码为550NoconnectionsallowedfromyourIP。问题分析发现,FileZilla有一个TEMPBAN策略导致连接受限,重启FTP服务后该策略被清除,问题得到解决。

今天新开了一个FTP帐号,连接的时候竟然提示:550 No connections allowed from your IP!其他的FTP帐号都能正常使用,这个帐号在别的网络里使用也是正常的,奇快的很,GOOGLE后,大概是说重启一下FTP,果断好了!

我的FTP server是:FileZilla Server 0.9.48 beta

操作系统:Windows 2008 R2 x64 SP1

FTP client:FileZilla 3.9.06


问题深究:

貌似FileZilla有个TEMP BAN的策略,重启后,这个TEMP BAN就清空了。

They will be addressed in the next generation version, which is currently being developed. No secure protocols supported - if you get this message, but you know that the site supports SSL, wait until the cache expires on its own, then try again, making sure the hostname you enter uses the "www" prefix (e.g., "www.ssllabs.com", not just "ssllabs.com"). no more data allowed for version 1 certificate - the certificate is invalid; it is declared as version 1, but uses extensions, which were introduced in version 3. Browsers might ignore this problem, but our parser is strict and refuses to proceed. We'll try to find a different parser to avoid this problem. Failed to obtain certificate and Internal Error - errors of this type will often be reported for servers that use connection rate limits or block connections in response to unusual traffic. Problems of this type are very difficult to diagnose. If you have access to the server being tested, before reporting a problem to us, please check that there is no rate limiting or IDS in place. NetScaler issues - some NetScaler versions appear to reject SSL handshakes that do not include certain suites or handshakes that use a few suites. If the test is failing and there is a NetScaler load balancer in place, that's most likely the reason. Unexpected failure - our tests are designed to fail when unusual results are observed. This usually happens when there are multiple TLS servers behind the same IP address. In such cases we can't provide accurate results, which is why we fail. Common Error Messages Connect timed out - server did not respond to our connection request, sometimes before we are dynamically blocked when our tests are detected No route to host - unable to reach the server Unable to connect to server - failed to connect to the server, it usually happens due to firewall restrictions Connection reset - we got disconnected from the server Unrecognized SSL message, plaintext connection? - the server responded with plain-text HTTP on HTTPS port Received fatal alert: handshake_failure - this is either a faulty SSL server or some other server listening on port 443; if the SSL version of the web site works in your browser, please report this issue to us Failed to communicate with the secure server - No secure protocol supported. Possibly this server only supports a draft version of TLS 1.3 SSL Report v2.4.1 比较上一次的信息,再分析下原因
