FTP logs can not be touched often, many people often post the inquiry. Honestly, such a waste of self, and waste others, often can't get a satisfactory answer. So each of the friends who wish to find resources from the FTP site must learn to analyze the cause of landing failure:
The so-called login prompt is some instructions and status prompts for two-way communication when landing, if you see a word like this, that is:
*** CUTEFTP Pro 2.0 - Build Dec 4 2001 ***
Status:> Get list "" ...
Status:> The FTP server 211 is connected to the FTP server 211. *. *. *: * (IP = 211. *. *. *: *) ...
Status:> Socket is connected. Waiting to welcome news ...
220 FTP server is started
Status:> Connected. Positive verification ...
Command:> User Software
331 User name okay, need password.
Command:> Pass *****
230 User logged in, proced.
Status:> Login is successful.
Command:> PWD
257 "/" is current Directory.
This thing is very important, please pay attention.
Common error analysis:
If you see the words below, and stay for a long time
Status:> The FTP server 211 is connected to the FTP server 211. *. *. *: * (IP = 211. *. *. *: *) ...
After seeing:
Error:> Unable to connect to the remote server. Socket error = # 10060.
Status:> Waiting for 30 seconds ...
There are two possibilities in this case:
As soon as the other party has not opened FTP or unable to connect, please contact the FTP administrator.
Two is because the port is fill in the error. Generally, the default is 21, but because this port is easy to conflict in some networks, the security is also debatable, so most FTP changes the port. If you don't fill in the port (FTP software will be default 21) or fill in errors, it will also cause a 10060 error.
If you see the words below:
Thu Mar 07 11:44:56 2002 530 Sorry, No Anonymous Access ALLOWED
Indicates that the FTP does not allow anonymous to log in, please contact the FTP administrator and get an account.
Thu Mar 07 11:46:29 2002 User Bugdown
THU Mar 07 11:46:30 2002 331 User name okay, need password.
THU Mar 07 11:46:30 2002 Pass ********
THU Mar 07 11:46:30 2002 530 Not logged in.
There are two possibilities:
1. Account or password input error is rejected to log in. Please make sure you don't enter an error (more complex password is recommended to fill in with copy paste, and pay attention to spaceless), then contact the FTP administrator to confirm that your account has not expired. Most of the FTPs currently change the password regular, so this error is the most common.
2. Use dynamic domain names such as peanuts, sometimes there will be such a phenomenon: if ftp is not open, some people use dynamic domain name to log in, the dynamic domain name service chamber will automatically transfer you to its own prompt ftp, which is likely to The password error is incurred, and it is also possible to log in to its server. The FTP established by IIS is likely to go to Microsoft server, and the phenomenon.
Too Mar 07 11:51:25 2002 421 Too Many Users - please try..
This is because the FTP manager sets the maximum number of landings of the account (or the domain name), and now you have reached this restriction, so you can't log in. Only waiting for other users to quit or use other accounts, you may enter FTP. Command:> pass *****
530 Not Logged in, Only One Session from Same IP Allowed At a Time.
Error:> Not logged in.
Status:> The connection is closed.
This account only allows single-threaded login, so note if you open multiple windows or already have a thread in download
The number of landings is full, and you have been trying to log in, there are three possible situations:
1. You finally squeeze in.
2. Talk about the window prompt error and see such words in the login error instruction:
Error:> The control connection is closed.
Indicates that the FTP server intercepts you frequently trying. You can continue to try back after it is determined; but slightly moral people should modify the spacing time of the FTP software on the interval of the retrieval attempt to a larger, generally advocate 30 seconds to 2 minutes.
3. You are Ban. Serv-U Server cannot automatically BAN IP, but managers can manually ban, some server-side software can automatically seal IP. The prompt by the BAN is:
Command:> Pass *****
530 Not Logged in, Unauthorized IP Address.
The above tips:
Command:> Pass *****
530 Not Logged in, Unauthorized IP Address.
That is to say, your IP is illegal, whether it is because of the reason, in short, unless you contact the manager and unsappur, there is no need to continue trial. Of course, managers may just be BAN you for a while, you can re-try again. But I must remember to change your attempt interval.
Sometimes it is not because of sealing you, but because the account limit is only partial license IP can log in, and you must contact the manager, please add your IP.
