Welcome to CDS’ Frequently Asked Questions.

Feel free to ask any questions about Cloud hosting, Internet access, network connectivity, setup procedures – anything Cloud. We will answer to the best of our engineers’ ability! This is a place to learn – so get started!

Answer: You can call our support line 24/7 or send mail to We can reset the password once your client ID is verified.

Answer: Generally, cloud computing users are:

Concerned about the cost of hosting services
Require rapid realization of distribution deployment
Require elastic expansion for business
Require high system availability and rapid recovery
Desire an easy management system

Answer: CDS Cloud supports all popular operating systems including Ubuntu, Debian, Redhat Enterprise Linux, CentOS and Windows server. If you need to install the system except for the pre-load, please contact CDS’ 24/7 support line or contact your sales representative.

Answer: When a terminal server is logged in through a remote desktop, the user may encounter an error stating that the terminal server exceeds the maximum allowable number of sessions, etc. and the terminal server cannot be logged in. There are two default links for terminal services. If a user turns off the remote desktop window rather than exiting correctly, the dialogue cannot be released and is kept open on the server occupying a session. When the number of logins reaches the maximum allowable value, the above prompt is received. The issue can be resolved by the following:

Input under command mode: (start –> operation)

mstsc /console /v:your server IP: remote port Example: mstsc /console /v:

Open the task manager after remote login – > users – >directly login normally after all links except for the current user are canceled.

Answer: BGP (Border Gateway Protocol)

BGP peering is an Internet protocol used among network operators that manage how packets are routed across the Internet through the exchange of routing and reachability information between edge routers. It provides the best routing decisions for networks interconnected in the BGP peering mode. BGP peering neighbors, called peers, are established by manual configuration between routers to create a TCP session on port 179. A BGP speaker sends 19-byte keep-alive messages every 60 seconds to maintain the connection.
An Internet service provider must obtain an AS (Autonomous System) number from regulatory authorities to be able to take advantage of direct BGP peering. CDS has been operating BGP networks since 1998 and currently holds two numbers: APNIC AS38353 and ARIN AS 63199.
Advantages of BGP machine room:
1. One IP address should be set for the server. The best access route is determined by the backbone router on the network according to routing hops and other technical indicators. Any system server resources will not be occupied. The best route can be selected for server uplink route and downlink route, thereby actually realizing single IP high-speed access.
2. Since the BGP protocol itself has features of redundant backup and loop elimination, mutual backup of routes can be realized when there are many BGP interconnection lines in the IDC service provider. Other lines can be automatically switched when one route is failed.
3. Networks can be highly scalable by using BGP protocol and IDC networks can be interlinked with other operators allowing single IP multiline to be easily realized. All interconnected users can achieve access rapidly. It can not be compared by double IP line.

Answer: Computing network traffic is a little complicated. Network flow regards Mbps as a unit. The normal document size regards MB as a unit. The conversion standard is 1 Byte = 8 bit.

2Mbps broadband is really 2M bit/s rather than 2M Byte/s. The formula therefore is:

8 bits = 1 Byte: 2Mbit = 2048Kbit = 256KByte

Therefore the maximum download speed of 2Mbps broadband is theoretically 256KB/s.

Answer: When a website cannot be accessed the cause can be a number of factors including the user’s network, computer settings, inter-state routes, etc.

Here is a simple way to test the route between your computer and the hosting server.

The operator should verify the user computer is correctly connected to the internet.

Then the Start –> Run on the left lower corner should be opened: input mstsc

Input the command ‘tracert your domain name (or IP address) – > Enter

If there are no notifications of ‘request timeout’, then the route between servers is operational.

If you observe timeout notifications such as ‘request timeout’, etc., then there is an error on the route which is not allowing the servers to connect. The IP location can be checked through the webmaster tool.
