Session manager

[GenieonWork]

Hi,

I installed the Untangle Lite on a virtual box (Hyper-V), and added Web Filter Lite, Protocol Control and Firewall.
Everything works fine so far (haven't had so much time to go through all settings yet, since I installed it Friday late afternoon).

However, I tried to Show Sessions, just to look what's currently going on.
But when I try to open it, I get an error:

Warning
An error occured:
java.lang.NullPointerException at com.untangle.uvm.engine.SessionMonitorImpl.getMergedSessions(SessionMonitorImpl.java

Has anyone else had this error yet, and more important, does anyone know how to fix this?

In between, nice an error message with 'Warning' as title

[dmorris]

Can you post the full output from /var/log/uvm/uvm.log?

welcome to the forums.

Thank you for your quick reaction.

Since I'm a Wintel-man, I'm not that good in Linux.
How can I mount a remote share on an Untangle-box so I can copy the log-file?
Or is there another way for me to retrieve this log-file?

Hmz...
Out of all sudden, I can now access the Session Manager.
Could it have something to do with me installing the Phish Blocker, Virus Blocker and Spyware Blocker? Somehow that 'fixed' the problem with the Session Manager?

Dang. I've had that exact problem ever since the 8.0 upgrade. Unfortunately, it hasn't healed itself as yours did.

Here's the log file:

Here's the log file:

thanks I will look into it.

[GenieonWork]

It started working for me after I installed mentioned Apps.

When I tried to get the errormessage again (was trying to see what it did with the mentioned log-file), I first ordered the data on the Protocol-column, in stead of the default Bypassed-column.
Than I got the results, not the errormessage.
