Problems with connection to the client

[jonas]

Hi.

We have an new server with a new install of 6.4.2.

When we open the client it does not start, it does not give us an error message.

Whe i look in the client log i can find the following error:

Client failed to start properly - Could not initialize class com.onaro.sanscreen.server.interfaces.ServerInterfacesUtils

Java version is 1.7.09

Does anyone have any idee?

Regards

Jonas

Jonas,

are you starting the client on the server itself (via RDP) or from your desktop?

Either way, I'd check the network settings of java (in the control panel) and change the default proxy settings to direct connectivity. And maybe delete the java cache.

Otherwise try from a different machine possibly with a different java version installed.

Hope this helps.

The problem occurs on both client and on the server itselfe(RDP).

I’m going to try a later Java version.

Hi Jonas,

it might also be a good idea to look into the client log file on the client machine: %HOMEPATH%\Local Settings\Application Data\SANscreen\configuration\xxxxxxxxxxxxx.log. If you have more than one file in the directory, look for the one with the matching time stamp and see if there's any useful hints in the log as to what might be causing the issue.

Also, make sure port 80 of the OCI server is reacheable and the Senscreen Server service is up and running.

Hi.

It turns out taht it seem s to be a firewall issue.

The oci server is behind a firewall withg port 80 and 443 open.

But the ociserver anseres back on some random 60000 port.

Is there any setting to get a fixed port range?

Mvh/Regards

I'm not aware of any way to change that.
I tried it out too and I could see tcp packets in the port range 4056-4191, but i think higher values are possible too, since the port numbers seem to grow sequentially with the packet numbers. Best to allow UDP/TCP and IP packets from the OCI server to the client host without restrictions. Or you'd have to stick with RDP to the OCI serevr, if the client is running from there. Best advice I can give.

Hope this helps.

The OCI client should make all of its communication to the https port of the OCI server - it may locally have some ports open, but all the network traffic should be to a destination port of 443, or whatever the port is.

The sanscreen-client.log would be helpful

This may be a name resolution issue.

Hi Thanks for the clarification.

It turned out to be a Java issue.
