NAME
vsys - Make AFS system calls from the command line

SYNOPSIS
vsys <call number> <parms>+

DESCRIPTION
vsys is a development tool to make AFS system calls from the command line. <call number> is the AFS system call to be invoked. <parms>+ are the values to pass to the system call. Knowledge of the AFS system call layer is required to know valid call numbers and parameters.

CAUTIONS
vsys is intended for debugging AFS at a low level and is therefore intended for AFS developers. System Administrators and AFS users should use the higher-level interfaces provided by the fs(1) manpage, the aklog(1) manpage, the klog(1) manpage, and the pagsh(1) manpage instead.

vsys provides a way to pass arbitrary data into the AFS system call mechanism. Caution should be taken when using or providing this binary on a system, as incorrect use as a privileged user could cause a system to panic, hang, or perform an unsafe operation.

PRIVILEGE REQUIRED
The issuer must be logged in as the local superuser root.
