A typical customer environment is heterogeneous and includes AIX, Windows, and Linux, which can be servers or clients. In many situations, an AIX Kerberos client needs to interact with multiple Kerberos realms hosted on a Windows or AIX Kerberos server to handle the requested services. This article explains the configuration details required to set the AIX Kerberos client to interact with multiple realms hosted on Windows Kerberos servers.
To cleanly shut down or hot swap storage hardware on a UNIX or UNIX-like system, you must be able to unmount any file system that uses storage on that device. However, you can't unmount a file system if files or directories in that file system are in use. The lsof and fuser commands can help you identify and terminate the processes that are using files on or executing from the storage devices that your system is using. Using these commands simplifies the traditional detective work associated with finding the processes that are preventing you from unmounting storage devices, decreasing frustration, and helping you proceed with critical system administration tasks.
