RE: [NV-L] Turning off polling at certain times of dayHi,

I just installed NetView on an AIX node and before yesterday, it was
working fine.  I ran :

export DISPLAY=<my PC IP>:0.0
. /etc/Tivoli/setup_env.sh
netview

and it worked.  But since yesterday, I received the 'Unable to open
display' message.  Nothing was changed or done to the node.  I would
appreciate any advice about this.  Thanks!
