It is not the intention at this stage in the book to investigate how Crystal Enterprise can be configured to work with proxy servers in any great detail. This is covered in some depth in the Administrators guide that accompanies Crystal Enterprise. However, some sample Socks configurations will be shown and there will be a brief discussion as to how Crystal Enterprise would operate effectively with each configuration.
Socks settings for each of the Crystal Enterprise servers are defined using the Crystal Configuration Manager (through the Connection tab).
Figure 26.9 illustrates the operation of Socks between the WC and the WCS.
Given this scenario, the Socks setting through the Crystal Configuration Manager should be the following:
Access control rules on the Socks server should be set to something similar to that shown in Table 26.5.
Source | Destination | Port | Action |
---|---|---|---|
WC | WCS | 6401 -requestport | Accept |
Otherwise | Reject |
There are a couple of points worth noting:
Figure 26.10 illustrates the operation of Socks between the WCS and the CMS.
In this instance, the Socks setting at Crystal Configuration manager should be the following:
Access control rules on the Socks server should be set to something similar to that shown in Table 26.6.
Source | Destination | Port | Action |
---|---|---|---|
WCS | CMS | 6400 -requestport | Accept |
WCS | Other Enterprise Servers | Default ports -requestports | Accept |
Otherwise | Reject |
Please note that when WCS makes the initial connection to CMS on port 6400, it will pass the host name to the Socks server. Thus, the Socks server must resolve the CMS hostname.
Figure 26.11 illustrates the operation of Socks between multiple servers in the Crystal Enterprise environment.
When multiple Socks servers are deployed in the network, the Crystal Enterprise Socks setup can facilitate the traversal of them. However, due care and attention should be taken in how the Socks servers are placed and traversed. In general, the Crystal Enterprise servers see these Socks servers as a chain, and the setup in the Crystal Console Manager should specify how to traverse them from the outermost to the innermost link.
In this instance, the Socks setting at Crystal Configuration Manager should be the following:
Access control rules on the Socks server should be set to something similar to that shown in Table 26.7.
Source | Destination | Port | Action |
---|---|---|---|
WC | WCS | 6401 -requestport | Accept |
WCS | CMS | 6400 | Accept |
WCS | Other Enterprise Servers | default ports -requestports | Accept |
Otherwise | Reject |
The point to note is that in the IOR for the CMS, the Socks server chain B-A is embedded. However, because the WCS has been configured with a local Socks server B, the program will do a comparison of these two Socks server lists and deduce that WCS only needs to go through A to reach the CMS.
