Firewall issue - Connecting BO XI 3.1 from .Net app - opendocument URL

[Former Member]

Hi,

Good day. We have a .Net application which connects to BO XI 3.1 to view the business objects reports. It is working perfectly when in my local machine and development & test environments. When it is being deployed in stage environment it throws the following error " System.ArgumentException: Sorry - you could not be logged on. CMS host 'servername' cannot be found on the network. Please verify the name and that network name resolution is working properly.".

We noticed that the stage web server is firewall restricted. Actually from stage web server we are trying to connect BO dev server which is not firewall protected. Though we have supplied respective ports for establishing a connection and viewing the report, it did not turn up positively.

Port # used for authentication purpose: 6400

Port # used for viewing the report using opendocument.jsp: 8080

I am in touch with network team to resolve the firewall restriction issue and I am curious to know what protocols (TCP / UDP / ICMP....) are being used for an authentication and viewing purpose. If I would get this information it will be much helpful for me to resolve the issue in a right direction.

Looking forward to hear about how to find which protocols are being used. Thanks in advance.

Partha.

That error doesn't mean a blocked port it means the host name is not resolving. Can you ping the CMS name from the workstation command prompt? The port error is something like "the server was contacted but there is no CMS running on port 6400"

Tim,

Thanks for your response. There was a firewall restriction in server and now it has been resolved and able to communicate through TELNET <SERVERNAME> 6400 in command window. Now, am getting the following error when I try to view the report from .Net application.

Transport error: Communication failure.(FWM 00001)

I tried creating a key to have the BO server value including port and also added an entry in hosts file with a strong name. This doesn't make any difference.

I'm wondering if still I need to do anything in firewall settings as the same application is working well in dev and test environment (no firewall) pointing to the Bo server. I guess, if this is occuring because of timeout issues. Appreciate your inputs further on this. Thanks in advance.

Cheers!

In the CMC > servers > Central Management Server there are port settings. When using firewalls you usually need to set them up too (formerly known as port/request port) The directions and the what the field is called should be in the admin guide key word firewall. Let me know if you can't find it and I'll look them up later today.

Basically by default the port setting (6400 is only for initial communication and the CMS then tries to switch to random ports for future requests unless this other port setting is enabled. If you can ping the host that's probably the last piece.
