Hi All,
While my LINUX SERVER installed we didnt' used all the space for partitions. with what tool I can create a new partition or mount point to use the free space.
I tried the command fdisk and diskdruid. They are not working.
Thanks in advance
With Best regards,

Have a solaris x86 running solaris 9.
Root disk - logical - mirrored.
I added 2 more disks today - and I have mirrored them using array configuration utility.
I did a reconfiguration boot - and now I can see the logical disk using format:
I then partitioned this the way I wanted (I hope)... (4 Replies)
I have 3 disks to partition in following file system.
c1t1d0 = 72gb
/prod1
/prod2
/prod3
/prod4
/prod5
I am first time using "format" command to do this. How can i name with specified size.

Hi all,
I'm kind of new to programming in Linux & c/c++. I'm currently writing a FileManager using Ubuntu Linux(10.10) for Learning Purposes.

Hi guys can someone please advise... are there 2 types of VM used in HP-UX? because i have seen 2 sets of commands the one uses hpvm* (hpvmstatus) then the other it starts with v* (vparstatus) (2 Replies)
Hello,
I am a new member of the forum.
I need an idea on how to partition the disk.
My situation is as follows:
I have two 3TB disks ognuno.In 6TB total then, but I have to do to force a RAID 1 so my space will be 3TB. I'll have to force install RedHat 5.8 and liquids is to be taken in... (4 Replies)

DESCRIPTION
TPM Quote Tools is a collection of programs that provide support for TPM based attestation using the TPM quote operation.
A TPM contains a set of Platform Configuration Registers (PCRs). In a well configured machine, some of these registers are set to known
values during the boot up process or at other times. For example, a PCR might contain the hash of a boot loader in memory before it is
run.
The TPM quote operation is used to authoritatively verify the contents of a TPM's Platform Configuration Registers (PCRs). During provi-
sioning, a composite hash of a selected set of PCRs is computed. The TPM quote operation produces a composite hash that can be compared
with the one computed while provisioning.
To use the TPM quote operation, keys must be generated. During provisioning, an Attestation Identity Key (AIK) is generated for each TPM,
and the public part of the key is made available to entities that validate quotes.
The TPM quote operation returns signed data and a signature. The data that is signed contains the PCRs selected for the operation, the
composite hash for the selected PCRs, and a nonce provided as input, and used to prevent replay attacks. At provisioning time, the data
that is signed is stored, not just the composite hash. The signature is discarded.
An entity that wishes to evaluate a machine generates a nonce, and sends it along with the set of PCR used to generate the composite PCR
hash at provisioning time. For this use of the TPM quote operation, the signed data is ignored, and the signature returned is used to val-
idate the state of the TPM's PCRs. Given the signature, the evaluating entity replaces the nonce in the signed data generated at provi-
sioning time, and checks to see if the signature is valid for the data. If so, this check ensures the selected PCRs contain values that
match the ones measured during provisioning.
A typical scenario for an enterprise using these tools follows. The tools expect AIKs to be referenced via one enterprise-wide Universally
Unique Identifier (UUID). The program tpm_mkuuid creates one.
For each machine being checked, an AIK is created using tpm_mkaik. The key blob produced is bound to the UUID on its machine using
tpm_loadkey. The public key associated with the AIK is sent to the entities that verify quotes. Finally, the expected PCR composite hash
is obtained using tpm_getpcrhash. When the expected PCR values change, a new hash can be generated with tpm_updatepcrhash.
The program to obtain a quote, and thus measure the current state of the PCRs is tpm_getquote. The program that verifies the quote
describes the same PCR composite hash as was measured initially is tpm_verifyquote.
