I can sucessfully encrypt/ decrypt 1 column, but Im under the impression there is also a way to encrypt the data being sent over the network by using a certificate? I can find lots of info, but no starting point or clear cut instructions. Could someone please assist?
TIA, cfr
Hi Guys.
I am looking for TSQL code for RC4 encryption and decryption.
I found VBcode for RC4 encryption, it will take atleast 2 days for me to go thru that and rewrite the whole code in SQL.
If anyone has the code, please provide me.
(I know sql does accept extended ASCII characters)
Thanks

Hi folks,
I'm trying to encrypt a small token of data on my client c# application and have it decrypted by SQL on the server side, the problem is i cannot find articles on the subject. I don;t really want to get involved with certificates but base the system on a simple symmetric key that is shared by both parties.
I'm attempting to use the TRIPLE_DES algorithm on both sides and thus far have used the decryptbypassphrase on the server side with the data encrypted on the client side by .Net with no initialization vector setup.
If anyone can recommend any articles or have example (client and server side) code for this situation it would be greatly appreciated.
Many thanks in advance

Does anyone know what my .net app guys need to share with me if encryption was done in the .net app but decryption needs to occur in certain sql queries? I read about master keys, certificates, symmeteric keys, algorithms etc but dont know how that stuff would carry over from the framework into sql. All I know is that the algorithm is AES_256, they must be adding authentication to the encryption and i know the hash algorithm, and symmetric keys are involved. Will they be sharing certain kinds of files with me that need to be registered in the db? Will I have to use CLR if I want the two worlds to come together?

Is there are ways to encrypt data in the table (SQL Server 7) and then retrieve (decrypt) this information?
Thanks
We like to secure datas.
Only a few people are autorized to read this information, but today, these informations are readable with a simple query with a query analyzer for exemple.
I'd like to encrypt datas with reversible function in one field of a table
Is there a function able to do this kind of work in SQLServer V7 or 2000 ?
hi guyz!! is it posible to ecnrypt data everytime i insert it to a table and decrypt it everytime I select it using the MS SQL 2005 alone?
like for example i have this query statement below
insert username,password users values ('daimous','my_password')
what i want is every time i insert a value to the password column that value should be encrypted first.
select username,password from users
everytime i select the value of the password column should decrypted.
Thanks in advance!!!
hi,

Hi there,
Using symmetric keys and certificates in SQL2005, can one assign users permission to only decrypt or encrypt data?
Reason would be say data capturer and data reader type roles. I tried to create some with the GRANT CONTROL and GRANT VIEW for certificates and definitions on Symmetric keys, but havent been to successfull.
Would be great if someone here can offer some advise on it, and if it's possible using SQL rights.
thanks
I encrypt my procedures using with encryption clause, but I do not how to decrypt again.
Is there a command or utility for encrypt and decrypt in Sql 2000? How about Sql 2005?

Hi,
We have migrated a CRM Database from SQLServer 2000 to SQLServer 2005.
Database contains very sensitive data about customer in text format (Datatype varchar(20)) how can i encrypt the same without any change in the table design.

What sort of traffic would be going on between the machine I am on Enterprise Manager and have a server registered (my local machine) to the actual SQL server? I haven't logged onto the actual SQL machine I only have it listed as a registered server and it's sitting there in the list with it's little green "started" icon.
I'm asking because i'm getting accused for a server going down. I opened my EM around the same time as this SQL server went down and some network people see my machine talking to the SQL server at the same time.
Any ideas? Thanks...
Hi,The application setup is: Access frontend + ODBC (TCP/IP) + MSSQL7Few days ago i was informed that the app generates high networktraffic. Thusi started to look for some savings.I found out (sniffer) that even if the client is idle every 30sek. aTCP packet comes from client to server, then answer goes back. Thepacket seems to be empty (TCP data is 1 byte: 0x00), the answer isempty as well. Seems like kind of watchdog. And it does not seem to berelated to ODBC refresh and any other option possible for setup inAccess client (I set those settings to different that 30sek. values,and 30 sek. traffic still exists).Does anybody know what those packets are for, what module isresponsible for them and how to change interval?My best regards for anybody reading this post,Mirek
View 6 Replies View RelatedI am having a problem and this may be more of a network issue bandwidth issue: When I ping from one of my dataservers to another dataserver it takes 10ms. However, if I ping from a fileserver to a dataserver it takes 1ms. Also, if I ping from a Citrix server to another Citrix server or one of the data servers, it also takes 10ms. What are my options?

I have a system set up with 2 servers, the master server replicating the data to the backup server. Each server has two network cards, 1 which links directly to the other server.
The problem is the replication is being routed round the network making the direct link useless.
How can this be ammended!!
They are both logging into the same primary controler.
I am open to sugestions
OK, I'm troubleshooting a performance issue on one of our production servers, but I really can't t-shoot and tweak in real-time, so I took a snapshot of "a day in the life of" my production server using the profiler.
I want to run the sql commands I collected on another server I set up identical to production, and play around there.
Does anyone know of a good tool to "replay" those captured commands onot another server?

We are using the following configuration:
2 stand alone Windows 2003 servers 64 bit.
Each have two Gig Network cards configured with different IP addresses.
Each running multiple instances of SQL Server 64.
I am trying to set up a mirror where mirroring traffic between servers will be dedicated to a secondary IP address on the second NIC.
I am also trying to avoid Windows authentication.
Interesting enough: Security Configuration screen suggesting you to use fully qualified TCP addresses and, at the same time, does not give you such an option...
Would someone please point me in the right direction?
Thank you.
I have a database of details of users that visit my site. Among other things, it saves the ipaddress and the date/time of the visit. I would like to be able to determine the unique visitors (by ipaddress) that i have on any given day. The problem though is that the data is saved as a date and a time, thus when I try and determine the unique visitors, since they are all a different time, MSSQL thinks they are all unique visitors. Any ideas how I can get around this without acctually modifying the data in the underlying table?

Query(a report) to list the technicians/traffic controllers separately with following details.
EmployeeId,Name,Salary,Address,UnionId, and the most recent medical examination date for traffic controllers
Employee (EmployeeId(p),Name,Salary,Tpye).
MedicalExamination(MedicalNo(p),EmployeeId,MedicalDate)

"Type" field in Employee table tells whether its a technicians or a traffic controller.only traffic controllers has medical examination.

Hello,
View 4 Replies View RelatedI looking for a way of measuring how many MB of outbound SQL data is being transferred during the course of a day from an OLTP instance. Data is pulled from this server by a DW in the same domain and adhoc via a linked server. I'm looking at perfmon but nit sure if this is the correct tool and if so which counters to use. I'm looking for the total MB/GB over the period not the MB per sec.
View 2 Replies View RelatedWould anyone have a suggestion on how to setup a partner to partner NIC configuration for heartbeats/mirroring traffic? I've been told this is the recommended setup but have not found much on how to do it. We currently have a teamed NIC config for redundancy, but would like to have a separate set of NICs on each partner so that mirroring traffic is not interrupted by any regular network traffic.
We also have a witness running in full safety mode. Does this mean partnerA and partner B both need NICs with a crossover cable between them AND is it recommended for the witness to also have extra NICs to both partnerA and partnerB (w/ crossover cables)?
Any suggestions/help/links on properly configuring this would be appreciated.
Ive read a few docs and i have some doubts about the implementation i ll make.
I will setup a FCI between ServerA and ServerB. So my databases will be running on server A or on ServerB. they will be replicated using AllwaysON to ServerC.
Because ill use a diferent vlan for AllwaysON replication iam having some doubts on how can i set the endpoints...
For example.
I ll have the following ips configured for AllwaysON replication on Server A, Server B and Server C 10.10.240.1/10.10.240.2/10.10.240.3
Database teste will be running on serverA. the endpoint configured will be 10.10.240.1 but when database fails over to Server B (using FCI) the ip configured there will be 10.10.240.2... so AO replication will stop working.
I tough on associating a virtual ip to the AllwaysON cluster resource but Microsoft doesn't recommend to alter AllwaysON cluster resource.
How can i implement this configuration?
I have been told that I need to setup a crossover cable between a Server that has an application to have a dedicated NIC (using a crossover cable) to a server that has SQL 2005 Sp2 for fast access. How is htis done as far as SQL Properties, and NIC Settings, How do I make sure SQL will transmit using that 2nd NIC?
Thanks,

Hello all,
We have a Windows 2003 Web Edition server serving a site through IIS. It connects to a Windows 2003 Standard Edition server running SQL 2000 SP3a.
This site receives the following error as seen in the topic:
[DBNETLIB][ConnectionRead (recv()).]General network error. Check your network documentation.
We've configured the server network utility to only allow TCP/IP connections. The connection string for the site is as follows:
<%
' FileName="Connection_ado_conn_string.htm"
' Type="ADO"
' HTTP="false"
' Catalog=""
' Schema=""
MM_connSpankMSSQL_STRING = "Provider=sqloledb;Data Source=SERVER_IP,1433;Network Library=DBMSSOCN;Initial Catalog=ourmaindb_1;User ID=ourmaindb_1;Password=hotcookies;"
%>
Any ideas or tips on solving this issue? We've noticed it is due to larger queries as smaller ones do work with no problems.
The servers are behind a BSD box running iptables, has 1433,1434 along with standard web ports wide open. Anything outbound is allowed.
Some further testing via ODBC on the IIS server improved things. No more connection pooling for the SQL Server driver allows for 1/3 of the query to run. Still 2/3s of it doesn't show up, and that general network error message appears.
Should have 330 rows if it works right.
Hi
While running a DTS, many times the error message: "[DBNETLIB][ConnetionWrite (WrapperWrite()).]General network error. Check your network documentation." appears.
Does somebody knows why?
I am running the DTS from a computer (not the server where the DTS is stored) and it is connected without any problem when this happens.

Hi Every one,
I am using .Net 1.1 for my web application.
And my database server is SQL Server 2005.
My application is running fine, as i can login to it and also able to view pages. But when i open Order management(having 3K records) its give me error,
General Network Error. Check your network documentation
I have also searched many articles and tried following solutions but nothing working
- connectiontimeout = 0, max pool size = 7500/100, pooling = false
- SSL disabling enforce security false as mentioned in microsoft kb article.
And there's nothing any issue with hardware/firewall as my application's login and other forms are working fine(which use same database with same connection string)
Can any one please help me to solve this error?

I use sqlclient to connect directly from my mobile 5 pocketpc to a sql server 2005 database on my desktop.
I use a sqldatareader to traverse the results of a query that delivers 2 fields: (1) the filespec, and (2) the image field.
I use a filestream with a binary writer to write the contents of the image data to the pocketpc's storage card.
I have a test table with 10 images, not one more than 4 MB. I cannot complete a test run prior to receiving the general network error.
The pocketPC is connected via activesync to the desktop, and I connect to the database with:
Integrated Security=false;
user id=sa
password=admin.
Any help with this strange error would be greatly appreciated.
