# The SendReqExec method starts a command on the remote
# server. The syntax of the command string depends on the
# default shell used on the remote server to run the command.
# On Windows systems it is CMD.EXE. On UNIX/Linux
# systems the user's default shell is typically defined in /etc/password.
# Here are some examples of command lines for <b>Windows SSH servers</b>:
# Get a directory listing:
#cmd1 = "show ver"
# Do a nameserver lookup:
#cmd2 = "show ip inter brie"
# List a specific directory. Given that the shell is CMD.EXE, backslashes must
# be used:
#cmd3 = "sh run"
# Execute a sequence of commands. The syntax for CMD.EXE may be found
# here: http://technet.microsoft.com/en-us/library/bb490880.aspx. Notice how the commands
# are separated by "&&" and the entire command must be enclosed in quotes:
#cmd4 = "\"cd \\temp&&dir\""
# Here are two examples of command lines for <b>Linux/UNIX SSH servers</b>:
# Get a directory listing:
#cmd5 = "ls -l /tmp"
# Run a series of commands (syntax may depend on your default shell):
#cmd6 = "cd /etc; ls -la"
# Request a directory listing on the remote server:
# If your server is Windows, change the string from "ls" to "dir";
