Hi Baljeet,
I think I can help. &: )
How can i check linux client machine status LUA (Live Update Administrator server).
As Sandra wrote, above: there is no way to ee the status of the Linux computers via LiveUpdate Administrator 2.x. Please use the optional SAVFL Reporter component to forward some information from the Linux computers to your SEPM. Here's an article with more information:

On to your second question:
I am using Symantec LUA for linux machine. But still my client machine going to internet for get update. how to change it.
The Linux computers will update from internet LiveUpdate sources by default. They need to be configured to use your internal LUA 2.x server. Here's an article with information on how to accomplish that:

Generally I create a liveupdate.conf file with the details of the internal location where the SAVFL computer can go for its updates, and drop this liveupdate.conf file into the /etc directory of the Linux computers.
Please let me know if this has been successful for you! &: )
With thanks and best regards,
Mick
