• How should I isolate computers with different roles on a network

  - by fishhead

  I work in an industrial plant and we have one network(physical wire) that us used for both office usage and for process systems. The office computers are only used for typical office needs but occasionally do connect to the process computers to obtain information from a sql server or for some other purpose. A new initiative is in the works and is rolling down hill from corporate and that is to standardize how the the computers are used at work and they would be severely locked down and only a standard set of applications will be allowed to execute. one of the requirements is to also have non office computers isolated from the company domain. our non-office computers are a mix of Man-Machine interfaces and sql-servers all running software that non standard. My question is, how can we divorce the control systems computers from the company domain but still have access to the servers from the company domain. thanks

• How best to backup 6x Win2k3 Servers

  - by saille

  We have a external HP LTO3 tape drive. It needs to backup 6 Windows 2003 machines every night. Servers are HP DL380 G3 and the tape drive is attached locally to one of them via SCSI. On a budget of $0, and a goal of keeping-it-simple, what is going to be the best way to backup these machines? What software to use? NT Backup? Or does HP have something better for free? We don't need image backups - file system + system state will be adequate. Do we need to copy the files to be backed up onto the machine with the tape drive attached? Edit: Let me ask a more focussed question: Would you use NT Backup or something else? No soap boxing please, we've after some quick advice from someone who's used a similar setup.

• Create a CDROM Bootdisk to update BIOS

  - by osij2is

  So, I have a Tyan Opteron board with a very old BIOS version. I realize Opteron's aren't exactly common like Athlons, Phenoms, Intel CPUs, etc. but my question revolves around updating the BIOS, however I don't have a floppy drive and there's no option to boot off of a USB key. Tyan has incomplete instructions on their website (link) on how to flash the BIOS via USB. So my second tactic has been to create a Windows 98 boot-able CDROM with the flash utilities on it. It's been years since I've made one but after going to sites like bootdisk.com and such I haven't had any success. Can anyone tell me step-by-step how to make a boot-able Windows 98 CDROM? I can't believe I'm having such a hard time doing this but I've failed on four different attempts and I must be doing something wrong or I'm not accounting for something.

• Cannot set "Language for Non-Unicode Programs" in Regional and Language Settings

  - by cornjuliox

  I'm trying to set the Language for Non-Unicode Programs from English to Japanese (I'm using Windows XP SP 3), but it won't let me. It looks like I've got the East Asian Language packs installed, but when I select "Japanese" from the drop-down box and hit "Apply" I get an error that says "Setup was unable to install the chosen locale. Please contact your system administrator". I'm already logged in as the administrator, and I've restarted several times but it still won't let me. Can anyone give me an idea as to how to solve this problem? Reinstalling Windows is absolutely out of the question.

• Tomcat and IIS6 on one server, multiple websites

  - by Rafe

  Windows Server 2003 with IIS6 and Tomcat 6.0.26. Three sites running on this server. One is PHP, one is ASP and the third uses Tomcat. The first two work flawlessly. The third is being a pain. Tomcat is installed and if called on the server itself by IP address xxx.xxx.xxx.xxx:8080 shows the welcome page. Calling the same address from an external machine gives a 'could not connect' error. Calling the ip address from within the server on standard port 80 gives me an error 324 (net::ERR_EMPTY_RESPONSE). Have tried using httpcfg to force listening only on ports within the ip range I'm using in a manner similar to question 35650 located here on serverfault but with no success. There are actually ten ip addresses on this machine but I'm only using three of them at this point. Any pointers on troubleshooting this would be appreciated!

• Implementing Variable Envelope Return Path (VERP) using Exchange

  - by iammichael

  We're looking into implementing Variable Envelope Return Path (VERP) for improved bounce processing for our application. Our current mail infrastructure is MS Exchange 2007 but are in the process of upgrading to 2010. We're also implementing Postini for spam filtering. Exchange doesn't support sub-addressing (see also this question on disposable addresses) -- and VERP is somewhat of a specialized application of sub-addressing. Are there any options for implementing VERP in Exchange without putting another non-Exchange SMTP relay in front of Exchange to pre-process incoming messages? Specifically could a transport rule be created that could match against the target (non-existing) recipient, store that recipient address in a special header added to the message, and redirect the message to a pre-created mailbox? Note: we have developer resources available if custom code could be used somehow.

• BootMgr is missing, usual fixes don't work

  - by parsley72

  I know this question has been asked before but I've tried all the usual fixes and nothing works. Basically the hard drive had two partitions with Vista and Windows 7. I've deleted the Vista partition to make more room and expanded the Windows 7 partition to fill the drive (using GParted). I've tried: Running Startup Repair - it doesn't find any problems. Setting partition to Active - worked. bootsect /nt60 c: - worked. BootRec /FixMbr - worked. BootRec /FixBoot - worked. BootRec /ScanOs - I get the message "Total identified Windows installations: 0" BootRec /RebuildBcd - I get the message "Total identified Windows installations: 0" BcdEdit shows a Windows Boot Manager and a Windows Boot Loader, both on C: partition. What else can I try?

• How to turn on SMTP relaying? Getting error: "SMTP Error: The following recipients failed [address]"

  - by Susan

  Attempting to configure some software on our server to send email via SMTP. When testing it, get this SMTP Error: SMTP Error: The following recipients failed [address]" Based on my research and a reply from the software's support team this error usually occurs because relaying is not allowed on the SMTP server from the IP address of the web server. The solution is to "Go to the configuration of your SMTP server and turn relaying on for your IP address" My question is -- how do I do this? Is this done from WHM? cPanel?

• Apache is running but there is no page displayed

  - by Michael Ozeryansky

  I am on a Mac OSX and I am using the built in PHP and Apache2. I have been setting up MySQL and finally when I got MySQL working my local site won't display. Do note that I did have the web server running and delivering PHP enabled pages, just no database connection. But my question is not about MySQL. I have changed various settings in the 'http.conf' file, and I have the line: '127.0.0.1 localhost' in my hosts file. I also have other alias' pointing to 127.0.0.1. I have checked everything I could about Apache and I have made sure that any message in the error_log is ok. I currently have my errorLevel set to debug, so I get all the messages. At this point (HOURS of self fixing) I think I need help. What can I provide for someone to figure this out with me. Thanks.

• How do ring and bus network connect to router?

  - by lantopology

  Sorry this is probably a very silly question, but for some reason i am confused. How does a LAN with bus or ring topology connect to a router and other LANs? For example in a star network they all connect to a switch which can then connect to a router, but where does a switch go and fit in a bus or ring topology? In this image of a ring network there is no switch: http://www.brainbell.com/tutorials/Networking/images/01fig04.gif would the switch in the ring network simply be placed alongside the other nodes? Thank you very much

• E-mail addresses with plus sign in MS Exchange

  - by Wilson

  Many users like to use e-mail address in the format "[user]+[tag]@[domain]" to facilitate local filtering of incoming messages. The semantics of that is that the message should be delivered to the mailbox belonging to "user"; the user would advertise his/her address with different tags to different potential senders and would then be able to filter incoming messages according to sender (and also to track who got the e-mail address from where). The question is: is it possible to get MS Exchange (2007) to deliver messages in this format properly? If so, how exactly? Internet searches seem to imply it is not a possibility...

• Word 2007 cannot open old doc files anymore

  - by nilsi

  Since last week I am unable to open old doc files with Microsoft Word 2007. Whenever I try that I first get a warning about converters being a security issue. (I can disable that in the registry). After accepting (or disabling) this warning, however, I just get the following error message: Unglütiger Datentyp (Word 6.0/95 für Windows & Macintosh which means in English: Invalid document type (Word 6.0/95 for Windows & Macintosh I tried to goolge both the German and the translated error message but did not find anything related. The files in question can be opened by other users for the windows terminal server without problems.

• Websphere SSL handshake with active directory cluster

  - by ring bearer

  We have a WebSphere based application that uses Active Directory(AD) based security configurations. Under WebSphere "Global security" we have configured the active directory server and connection parameters. Active directory server is actually a cluster of four servers, say, serverdc01, serverdc02,serverdc03 and serverdc04. Each of these servers have their own root certificate with CN=serverdc01, CN=serverdc02 ..so on. So to set up SSL communication, I need to retrieve certificate of active directory and save it in WebSphere's trust store. When I retrieve certificate by putting AD server name, port and retrieve certificate I randomly get certificate of one of the serverdc01,serverdc02 ... Then I save that certificate to trust store. Question is : Do I have to save certificate from each of the serverdc01,serverdc02 ...in cluster to WebSphere's trust store? What are general strategies so that each server in the cluster does not require its own root certificate?

• Where is custom icon information stored in Mac OS X Snow Leopard?

  - by AmazingRobie

  I have an external Lacie hard drive connected via USB to my Macbook Pro which is running Snow Leopard. I have nothing but music on the external drive with every album sorted in it's own individual folder and have changed all of the individual folder icons to display the album art of the songs from the album inside. I want to reformat my laptop, but I'm afraid if I do that, the album art will disappear if it's stored on a system file within the main hard drive OS. My question is this, is the information which tells the OS to display the album art listed in a hidden system file on the external Lacie drive or my laptop hard drive and if I reformat will I have to reassociate all of the album art to the folders on the external or will it keep it's associations. Thanks in advance.

• Compress, encrypt and upload a directory to an FTP server in Linux

  - by Kristoffer L

  I want to accomplish something rather simple (at least it would seem to be): Compress a directory Encrypt the compressed file Upload the compressed & encrypted file via FTP I also want to accomplish this in an automated fashion on Linux server. TrueCrypt is not really an option in this case as it seems it can't compress a single file. Instead you have to make a volume that you mount and move the files into. This question answers how to do the the upload and I know how to compress a directory. It is just the encryption that's giving me problems.

• .htaccess redirect for www in parent folder and children react

  - by ServerChecker

  We were having a problem with the Norton seal not showing up on our affiliate marketing landing pages (landers). Turns out, the Norton seal was super picky about the "www." prefix. I had folder paths like /lp/cmpx where x was a number 1-100 and indicated advertising campaign number. So, to remedy this, I stuck this in my .htaccess file right after the RewriteEngine On line: RewriteCond %{HTTP_HOST} ^example\.com RewriteRule ^(.*)$ http://www.example.com/lp/cmp1/$1 [R=302,QSA,NC,L] Trouble is, I had to do that under every campaign folder, changing cmp1 to whatever the folder name was. Therefore, my question is... Is there a way I can do this with an .htaccess file under the parent folder (/lp in this case) and it will work for each of the children? EDIT: Note that I stuck an .htaccess file in /lp just now to test: RewriteEngine On RewriteCond %{HTTP_HOST} ^example\.com RewriteRule ^(.*)$ http://www.example.com/lp/$1 [R=302,QSA,NC,L] This yielded no effect to the /lp/cmpx folders underneath, to my dismay.

• Is there a "rigorous" method for choosing a database?

  - by Andrew Martin

  I'm not experienced with NoSQL, but one person on my team is calling for its use. I believe our data and its usage isn't optimal for a NoSQL implementation. However, my understanding is based off reading various threads on various websties. I'd like to get some stronger evidence as to who's correct. My question is therefore, "Is there a technique for estimating the performance and requirements of a certain database, that I could use to confirm or modify my intuitions?". Is there, for example, a good book for calculating the performance of equivalent MongoDB/MySQL schema? Is the only really reliable option to build the whole thing and take metrics?

• Can I Send An Email From An Email Account That Has Email Forwarding Set Up?

  - by mickburkejnr

  Stick with me on this one, I couldn't think of a correct way to ask the question! I have a domain registered, but it isn't attached to a hosting package or e-mail account. I will do soon, but not at the moment. Right now, I would like to set up an e-mail forwarding scenario. So, I could have the email [email protected] forward to [email protected]. I know this much is possible. What I would like to do, is using the gmail account is to keep the forwarded e-mail address when replying. So when I reply to emails sent to gmail through my e-mail forwarding, I would like any reply to say it came from [email protected] instead of [email protected]. Is this possible? If so how would I go about it?

• Set default expand/colapse state on pivot tables

  - by CLockeWork

  The Setup I have a pivot table in tabular form pulling data from an Analysis Services Cube. I want to calculate the number of days between two dates, but the setup will only allow me to pull in all date elements, not just the date. I’ve been able to deal with this easily enough by just grouping all the columns: The Problem The default state for the expand/collapse buttons in the image above is often collapsed, but that means the dates I need aren’t there and you have to open the group and manually expand them. This also happens in some random ways (as shown in the image) where only some rows expand. The Question I need a way to set these sections to always be expanded, so that the user never has to open the group to expand the rows. Ideally I’d like to avoid VBA because our end users often block it, but if that’s what’s needed then so be it. Is there a way to set my pivot table to never collapse it’s predefined groups? Note the end user is using Excel 2010

• Problems with Xen installation

  - by Rodnower

  Hello, I have CentOS 5.4 installed. Now I'm trying to install Xen with out connecting to Internet (I have any driver for modem, so I search on Inernet only from Windows). All I have are 7 installation disks. First I done was to find kind of some add/remove programs wizard but it needed connection to Inernet. Second I try was to find Xen rpm on all disks and install it. But I fell on some dependency of some dependency. Third I attempted was to boot from first disk and do upgrade, but also it was unsuccessfully... So my question is: is there some way to install Xen from CentOS installation disks with out network? Thank you for ahead.

• Hardware needs for video conversion server

  - by artaxerxe

  I would need to build a Linux server that will have as its main task to perform the video conversion. For video conversion, the most likely I will use FFMpeg tool. Question: Can anyone tell me if for improving this automated video conversion a video card will improve the process or not? The idea is that I will get movies at a very high quality that I will need to be converted in formats available for different devices (iPhone, iPad, etc.). That conversion will be performed through a CLI (command line interface). I will need that conversion to be done in the least time possible (ok, that's a kind of saying, not an absolutely specified short time).

• Drivers for Quick Cam pro 9000 on Windows 7

  - by runaros

  I have a Logitect Quick Cam Pro 9000 that I want to install on my Windows 7 installation. The user manual specifies that I have to install the software before I install the camera. But my experience is that software from hardware vendors tend to decrease computer performance, so I was wondering if this camera will work by only plugging it in and letting Windows 7 find and install the drivers for it. I could've just tried installing it of course, but again, hardware vendors are notorius for fucking up things, and I wouldn't want to make it impossible to install the camera by doing things in the wrong order, hence the question here on SuperUser because I assume somebody is more knowledgeable than me on this subject.
