Prosecutor client input content is clicked on and is started to connect, and user side shows a numeral, and this numeral is told operation maintenance personnel by user,
This numeral of operation maintenance personnel, as port numbers, coordinates the server that the ip of transfer server accesses this far-end to be operated.
Wherein, port release module is used for exporting available and unappropriated port numbers list, and it is by default port model
Enclose array, unavailable port numbers are rejected in test one by one, thus available and unappropriated port numbers in the range of filtering out, and by this
Described port numbers form list a bit, and described port numbers list is output as a web page.
Specifically, as shown in Fig. 2 being the schematic flow sheet of port release module, the input of port release module is default
Port range, TCP process is carried out by logic below, output result be a web page (index.htm),
Wherein comprise available, there is no occupied port numbers.
Wherein, it is used for being manually entered ip and port numbers by user by prosecutor client, input slogan list is simultaneously chosen
Can output effective ssh in connectivity port connect.
Specifically, as shown in figure 3, being the schematic flow sheet by prosecutor client, by prosecutor client input be ip and
Port (informing from operation maintenance personnel), is output as a ssh being interconnected with transfer server and is connected, by prosecutor client
Mapped come completing port by logic as shown in Figure 3 and connect.
Wherein, ssh connection pool is used for inputting effective ssh and connects and export external listening port.
