Greetings,
I work as a Network Security Engineer. I wish to support this project but the client cannot successfully connect to get data. I am on a dedicated connection, behind a firewall, and this is the only app. that doesn't seem to be able to connect through the firewall. Streaming audio works. Downloads work. SSH works, everything client-initiated works, except for WCG. This makes me think there is some server-initiate communication that my firewall rejects. Is there a protocol usage specification? What protocols and ports are used for negotiation? Does the client require some sort of open inbound port? I hope not. If there is a published specification, please point me to it. If not, please publish one. I'd prefer to read a published spec. then to take a sniffer and figure it out. Thanks |

----------------------------------------I don't think that it will answer all of your questions, but it does discuss the outbound ports that need to be open and the possible requirement for a PROXY server: http://www.worldcommunitygrid.org/join_now/connecting_to_the_server.html Since you are involved in network security, you might also want to read http://www.worldcommunitygrid.org/join_now/privacy_and_security.html Finally, there is an architecture document at http://www.ud.com/rescenter/files/mp_architecture.pdf and another document at http://www.ud.com/rescenter/files/mp_platform_security.pdf which discusses platform security. These are both published by United Devices, the developers of the Grid application that the WCG uses. If that doesn't provide all the answers you need, let us know in another posting to this thread. There are a number of WCG users willing to share their expertise in these forums. [Edit 3 times, last edit by Former Member at Dec 5, 2004 3:10:23 AM] |

Greetings, I work as a Network Security Engineer. I wish to support this project but the client cannot successfully connect to get data. I am on a dedicated connection, behind a firewall, and this is the only app. that doesn't seem to be able to connect through the firewall. Streaming audio works. Downloads work. SSH works, everything client-initiated works, except for WCG. This makes me think there is some server-initiate communication that my firewall rejects. The agent acts just like a web browser. All communication is client initiated and only happens when the agent needs to send results and download workunits. Is there a protocol usage specification? What protocols and ports are used for negotiation? Does the client require some sort of open inbound port? I hope not. If there is a published specification, please point me to it. If not, please publish one. I'd prefer to read a published spec. then to take a sniffer and figure it out. See previous post from Dave Bell. It was pretty thorough.
