Viewing protocol entries related to security
There are two commands that can be used to view the relevant security
information besides the entries made to the error log (which can be viewed by the
errorlog command): The commands are lsgcl, for listing the global command
log, and lsfailedlogin, for listing failed login attempts that may give a clue to
whether the security of the Virtual I/O Server might be at risk.
The lsgcl command takes no options and lists the commands executed in
historical order. Example 5-54 provides sample output of this command.
