chmod a+x setup-xxx.bin
Also use root account to run this installation.
DualShield installation package also supports console installation, which means you can install DualShield in ssh.
./setup.bin -- -console
Use the command bellow to start/stop DualShield on Linux.
/etc/init.d/dualshield start
/etc/init.d/dualshield stop
Use the command below to remove DualShield installation.
/usr/local/dualshield/Uninstaller/removedualshield.sh
It assumes that DualShield is installed in the folder "/usr/local/dualshield". Make sure you execute the command with root privilege.
