get the version information of SQL server

Microsoft support has a web page for this.

In short,
1. run 'select @@version'.

Version Number	Service Pack
6.50.479	SQL Server 6.5 Service Pack 5a (SP5a) Update
6.50.416	SQL Server 6.5 Service Pack 5a (SP5a)
6.50.415	SQL Server 6.5 Service Pack 5 (SP5)
6.50.281	SQL Server 6.5 Service Pack 4 (SP4)
6.50.258	SQL Server 6.5 Service Pack 3 (SP3)
6.50.240	SQL Server 6.5 Service Pack 2 (SP2)
6.50.213	SQL Server 6.5 Service Pack 1 (SP1)

7.00.699	SQL Server 7.0 Service Pack 1 (SP1)
7.00.623	SQL Server 7.0 RTM (Release To Manufacturing)

if the version number string is started with "8.", "9." or later, then run
"SELECT SERVERPROPERTY('productversion'), SERVERPROPERTY ('productlevel'), SERVERPROPERTY ('edition')"

The following results are returned:

• The product version (for example, 8.00.534)
• The product level (for example, "RTM" or "SP2")
• The edition (for example, "Standard Edition"). For example, the results resemble the following:
  
  8.00.534 SP2 Standard Edition

full disk encryption and filesystem encryption

eCryptfs seems support TPM. in its README,
...Future versions of eCryptfs will allow hardware token devices, such as a TPM chip, to protect your secret keys....
But there is a file named ecryptfs-utils-83/src/utils/ecryptfs_generate_tpm_key.c.
It is necessary to look into further.
eCryptfs: An Enterprise-class Cryptographic Filesystem for Linux introduce the eCryptfs in detail.


MetFS (FUSE) doesn't support TPM by observing its source.

EncFS (FUSE), no clue now.

CryptoFS (FUSE) doesn't support TPM by observing its source.


TrueCrypt (On-The-Fly Disk encryption) doesn't support TPM explicitly.

Full disk Encryption in wikipedia is a good start for information of this kind.

Fedora Core 4 support disk encryption. (dm-crypt ?)
Fedora's Release note: FeatureEncryptedFilesystems outline something on this topic.

RSA and SSL weak keys ?

ssl weak key generation (supposed to effect only debian). By reading the document, I think it is not really weak key on RSA, but debian's patch on OpenSSL causes predictable rsa key set.
