Top Forums UNIX for Dummies Questions & Answers PROM password for UNIX workstation. Post 21020 by killerserv on Thursday 9th of May 2002 05:27:06 AM

On most flavours of Unix, it is possible to boot off of a CD-ROM and gain root access to a system. This is now becoming common knowledge.

The PROM password can be set to restrict operation of certain PROM modes. With a password set, any attempt to do anything other than a standard system boot requires that the password be reentered. The password is remembered after the system is powered off.

So if you ask me i will tell PROM password is genuinely good especially if you wanted all your data's in your server not to be intruded.

NAME
di_prom_prop_data, di_prom_prop_next, di_prom_prop_name - access PROM device information SYNOPSIS
cc [ flag... ] file... -ldevinfo [ library... ] #include <libdevinfo.h> di_prom_prop_t di_prom_prop_next(di_prom_handle_t ph, di_node_t node, di_prom_prop_t prom_prop); char *di_prom_prop_name(di_prom_prop_t prom_prop); int di_prom_prop_data(di_prom_prop_t prom_prop, uchar_t **prop_data); PARAMETERS
node Handle to a device node in the snapshot of kernel device tree. ph PROM handle prom_prop Handle to a PROM property. prop_data Address of a pointer. DESCRIPTION
The di_prom_prop_next() function obtains a handle to the next property on the PROM property list associated with node. If prom_prop is DI_PROM_PROP_NIL, the first property associated with node is returned. The di_prom_prop_name() function returns the name of the prom_prop property. The di_prom_prop_data() function returns the value of the prom_prop property. The return value is a non-negative integer specifying the size in number of bytes in prop_data. All memory allocated by these functions is managed by the library and must not be freed by the caller. RETURN VALUES
The di_prom_prop_data() function returns the number of bytes in prop_data and prop_data is updated to point to a byte array containing the property value. If 0 is returned, the property is a boolean property and the existence of this property indicates the value is true. The di_prom_prop_name() function returns a pointer to a string that contains the name of prom_prop. The di_prom_prop_next() function returns a handle to the next PROM property. DI_PROM_PROP_NIL is returned if no additional properties exist. ERRORS
