forgot password red hat ?
Dear Forum savants,
I have a problem that I am not sure how to overcome. Two years ago I had
a friend build me computer with a linux os (red hat) for learning purposes. It happens to have an oracle server on it as well... Anyway , because of personal reasons, I lost complete interest in learning activities but kept my maching hoping that someday I will get back into it.
Now I am ready but can't seem to remember my passwords to log into linux as a user and I also don't remember what I had set my root password to.
Can someone here tell me of how to recover access to my machine ?
My level is beginer. Thanks in advance.

GRADM(8) System Manager's Manual GRADM(8)
NAME
gradm - Administration program for the grsecurity RBAC system
SYNOPSIS
gradm [ -E ] [ -R ] [ -C ] [ -F ] [ -L <logfile> ] [ -O <filename|stream> ] [ -M <filename|uid> ] [ -D ] [ -P [rolename] ] [ -a <rolename>
] [ -n <rolename> ] [ -p <rolename> ] [ -u ] [ -V ] [ -h ] [ -v ]
DESCRIPTION
gradm is the userspace RBAC parsing and authentication program for grsecurity
grsecurity aims to be a complete security system for Linux 2.4. gradm performs several tasks for the RBAC system including authenticated
via a password to the kernel and parsing rules to be passed to the kernel.
OPTIONS
All options to gradm are mutually exclusive, except for -L and -O.
-E Enable the RBAC system
-R Reload the RBAC system (only valid while in admin mode)
-C Perform a check of the RBAC policy, running the same analysis against it that is performed when enabling.
-F Toggle full learning mode. If used only with -L, it enables the RBAC system in full learning mode. If used with -L and -O, it
parses the full learning logs and generates a complete ruleset.
-M <filename|uid>
Remove an execution ban on a given uid or filename that has been put in place by the RES_CRASH resource restriction of the RBAC sys-
tem.
-L <logfile>
Parses the learning logs. Accepts an argument which specifies the logfile to scan for the learning logs. If "-" is specified as
the logfile, stdin will be used as the learning log. This option can be used with -E, -O, or -F.
-O <filename|stream>
Specifies output mode. Requires a single argument that can be "stdout", "stderr", or a regular file. Only used with -L or -F.
-D Disable the RBAC system
-P [rolename]
Without an argument, it sets the password for administering the RBAC system. With a role name as an argument, it sets the password
for that given special role.
-a <rolename>
Authenticate to a special role that requires a password.
-n <rolename>
Authenticate to a special role that does not require a password.
-p <rolename>
Authenticate through PAM to a special role.
-u Removes yourself from your current special role, reverting back to the normal role selection. To be used, for instance, for logging
out of an admin role without exiting your shell.
-V Displays verbose policy statistics when enabling the RBAC system or checking the RBAC policy. Can only be used with -C, -E, or -F
-L <filename>
-h Display help information
-v Print version information and exit
REPORTING BUGS
Please include as much information as possible(using any available debugging options) and send bug reports for gradm or the grsecurity RBAC
system to spender@grsecurity.net.
