Unfortunately, theinter-machine communication is insecure and wide open to snoopers. Weve barely scratched the surface withour explanation, but youve now seen enough to understand xforwarding. Now that youve seen general tcp port forwarding, we move to anew topic forwarding of x protocol connections.

Ssh makes the communication secure by tunneling the x protocol. For example, the operator reads the value of the left variable, adds the value of the right operand to it, stores the sum back into the left variable as a side effect, and returns the sum as the value of the expression. The behavior of this operator depends on its position relative to the operand.

If the first operand evaluates to , regardless of the value of the second operand. Shifting an integer left by 10 3 00011011 3 00000011 3 278-50 2 11001110 2 11110011 -13 ! -504 operator, except that it always shifts zeros into the high-order bits of the result, regardless of the sign of the left-hand operand. If is a method that expects no arguments, the method can be invoked with. X is the ,an abstraction for the screen managed by an x server.

    These can be shell scripts or anykind of executable program. For example is used as a binary operator, it subtracts its second operand from its first. For example as weve already seen, parentheses can also be used as an operator to perform narrowing type conversions, or casts.

    In order for x forwarding towork, your x server must accept the proxy x connections from your sshclient. The first operand of this operator is the type to be converted to it is placed between the parentheses. For floating-point calculations, however, division by zero simply yields an infinite result or nan 73 evaluates to 273.

    The comparison operators consist of the equality operators that test values for equality or inequality and the relational operators used with ordered types (numbers and characters) to test for greater than and less than relationships. The following material is to aid your understandingand satisfy any intense cravings for tech talk (both yours and ours). So far in this chapter, weve learned about the primitive types that java programs can manipulate and seen how to include primitive values as as symbolic names that represent, or hold, values. In other words, it converts a positive value to an equivalently negative value, and vice versa.
