Application error with initializing ASTK

When I try to open ASTK on desktop using LiveDVD, it comes with error message in initialization stage and stops there.

Messages Dialog:
\" Get information about the configuration of localhost. Please wait...
External command on localhost:
/opt/aster/ASTK/ASTK_SERV/bin/as_serv as_info
Process number: couldn't execute \"rsh\": no such file or directory\"

Application Error Dialog:
\"Error: extra characters after close-quote\"
\"extra characters after close-quote
extra characters after close-quote
while executing
\"ashare::attend couldn't execute \"rsh\": no such file or directory /tmp/astk_root/.file_rexec_outerr_403060741 .fen_about\"
(\"after\" script)\"

How to solve such problem?

I have the same problem and i have not yet a solution. But when You take the default settings of the network, it means the network properties of the LiveDVD, the ASTK will run without this error. So, if You have already installed the network connection, go this step back.
I will search for the reason for this problem and i will write it on this page.

I suffered something like that myself (on a installed version of CAELinux) and I had to install the rsh and rsh-server packages manually. Afterwards rsh needed to be enabled within the xinet deamon. It seemed to me that aster uses rsh to connect to localhost.

Hope this helps.
