When the Internet is connected but the connections have failed please check the DNS server setting：
  ‧ 140.112.254.4
  ‧ 140.112.2.2 

A Mail Server is responsible for receiving and sending your mails. All emails you send and receive have to go through the server. The NTU has 2 email servers so when you need to use either Netscape or Outlook to send and receive emails, the mail server settings are as follows :
For faculty members: ccms.ntu.edu.tw, Email Address is: xxxxx@ccms.ntu.edu.tw 
For students: ms.cc.ntu.edu.tw, Email Address is: xxxxx@ms.cc.ntu.edu.tw 
xxxxx is your account name. 

FTP is the abbreviation for file transfer protocol. As implied by name, it is a protocol designed for transferring files. FTP is not confined to some specific operating systems (such as WINDOWS), as long as the standard RFC959 and TCP/IP protocol are followed, files can be transferred across different operating systems, such as WINDOWS and RedHat Linux. As a result of the popularization of applications on websites, more and more people transfer files directly via HTTP, though, there are still many resources of information engineering, computer networking, and even academy are transferred via FTP. It is precisely because it is simple and fast (little overhead during transmission processes). However, we should note that user information as well as files in simple FTP are transferred in plain code, which may insinuate doubts of security. This can be dealt with through SSH-FTP.
Common FTP server software: ftpd, vsftpd, FileZilla FTP Server, Gene FTPd, etc.
Common FTP client software: ftp, FileZilla FTP Client, SmartFTP, etc.

As there are many machines in the University, they are divided into different domains. For example: The IP address of the C&INC workstations is 140.112.8.xxx, and therefore the workstations are on the NTU .8 domain. Every domain has a gateway that connects with other domains and each gateway needs to use an IP address. The gateways are regularly set at 254 of each domain, therefore, the IP address of the gateway on the .8 domain is 140.112.8.254.
The gateways for other domains would therefore be 140.112.xx.254, where xx is your domain. 

IP addresses are usually difficult to remember; therefore, it is easier to give your machine a name, and then register it on the DNS so that others can find you via the DNS. Of course the users must register with network administrators for them to configure your DNS in the network environment.
NTU (Primary) DNS: 140.112.254.4 (Secondary) DNS: 140.112.2.2
