• Single NFS folder shared across multiple clients

  - by parthi_for_tech

  I'm trying to mount a single NFS folder from server say "/share/folder" to multiple clients up to 32 clients, and the clients tries to access the folder and create files. The problem I'm facing is that when I execute the write command I see only one client is able to access the folder the remaining clients are blocked and not able to proceed to write. So, is whatever I'm trying to do above is correct? Can we write/read files from the same folder on multiple clients? if yes how can I do it prallel? Kindly advice! Thanks

• How to access an node of an LAN via WAN?

  - by gilzero

  Lets say I have a router that is connected to the Internet. An WAN IP address is given by ISP. It is using PPPoE ADSL, the IP address is not static, every time it connected, assigned a different IP address. There is an web server 192.168.0.100 running in the LAN. I heard something like DMZ + DynDNS can do the job? But not sure what these are and how they work. Any there way(s) to access the local node 192.168.0.100 via WAN, so that I can reach that node even I am not home. Thanks for any advice.

• Dell PowerEdge 6850 Degraded HDD

  - by Matt

  Good Morning, We have a dell power edge 6850 with a degraded drive in the RAID array. I have never had to recover such an issue, so any help or advice would be welcome. Basically it hasn't affected the server at an operating system level, but has slowed down performance, I have a replacement drive in hand but as this is our main database server I want to proceed with extreme caution. My options as I see them are - Can I just hot swap the degraded drive with the new one and the data will automatically re-sync and we are all back to normal presumably this is dependant on the current raid configuration? reading various comments on-line I may need to re-configure the RAID array and re-build the broken drive? This screams disaster to me with the main worry being that I wipe any other data. Option 1 would of course make my day. Thanks in advance

• Why can't I reconnect to my Philips SHB9000 bluetooth headset?

  - by Thomas Eyde

  When I connected my Philips SHB9000 bluetooth to my Windows 7 (64 bit) for the very first time, it worked well. I had to manually change the default playback device, but otherwise it worked. Then, when I start up my computer from standby, it's nearly random when I can reconnect or not. My last option is to remove the bluetooth device and reconnect it. But now, even that doesn't work. The sad thing is, this used to work better on Windows 7 beta. Windows Update has a new driver which fails to install. Searching for this driver yields nothing. I thought all vendors had an official site for their drivers? Well, Philips seems to have none. If there is no answer to this problem, my advice is to NOT buy this headset. It's good looking, the sound is nice, but what need do we have from that if we can't use the bloody device?

• recyle application pool,Warm up scripts-Performance tuning in Sharepoint WCM site

  - by joel14141

  I was trying to tune WCM public facing site we have in Sharepoint . I have following doubts By default application pools are set to recycle themselves at 2 am in night and because of that we need warm up scripts . But As I was googling on this topic I found mixed reactions on this some MVP are saying its not advisable to recycle application pool daily and some say otherwise so I am confused. Because if I am not doing recycling application pool then I don't hv to use warmup scripts . But as my site is public facing and its all around the globe so is it advisable that I should recycle it daily as it will affect the performance of my site even though I would run warm up scripts once I don't think so it wud be as good as it should be ....Any advice on that?

• Mini-jack problem with Sony Vaio (running XP)

  - by qftme

  I have a five year old Sony Vaio laptop (vgn-fw31m) that has had impact damage to the audio-output mini-jack for about the last year or so. In a recent discussion with my brother, we wondered whether it would be possible to write a program that would enable windows to use the microphone mini-jack input as the audio-output? As I currently use this laptop for work I am not keen to risk pulling it apart in order to replace the components comprising the audio-out. I therefore 'hope' that a programming solution exists. I would really appreciate any advice on this and eagerly await your response. Kind regards, qftme :)

• Is there a way to set up message moderation in Exchange 2007?

  - by Nate Pinchot

  Is there a way to get a feature in Exchange 2007 similar to message moderation in Exchange 2010 through the use of third party tools or otherwise? I've Googled things like "exchange 2007 outbound email approval" to no avail. We are working on getting Exchange 2010 implemented but I need an interim solution if at all possible. The reason for this is from a customer service perspective. I am willing to use a small process to be a smart host if needed. I would appreciate any suggestions or advice. Edit: My apologies, I should have been more clear that I am trying to moderate/approve outgoing email from certain users, not moderate/approve email sent to a distribution group.

• Windows7 home 64bit + Outlook 2010, multiple non-concurrent users

  - by Jim Taylor

  We have one windows computer shared by eight people. I have set up separate login accounts for each user. One account has administrative privileges, the others are standard users. We installed Outlook 2010 with the intention that each user could access their own email separately, without seeing the mail of other users. This has not worked as we intended. When the administrator logs in to each standard user account and starts the outlook mail setup, he is prompted for the administrative password, and then sets up the mail account. When accessing the outlook mail program after setup, each mail account shows as a separate tab in a communal inbox, rather than a separate mail box for each user. How would we accomplish the desired separation of Outlook mail accounts? Thanks for your advice Jim T.

• SSL 3.0 warning in Chrome on Ubuntu 10.04LTS

  - by Leopd

  I'm running Apache2 with SSL on Ubuntu 10.04LTS. Chrome gives me this annoying warning when I inspect the certificate: The connection had to be retried using SSL 3.0. This typically means that the server is using very old software and may have other security issues. The relevant part of the apache config looks like: SSLEngine on SSLCertificateFile /etc/ssl/... SSLCertificateKeyFile /etc/ssl/... SSLCACertificateFile /etc/ssl/... SSLProtocol -all +SSLv3 +TLSv1 The last line I added to try to address this problem, but it's not working. Any advice on properly enabling TLS?

• Determine precision and scale of particular number in Python

  - by jrdioko

  I have a variable in Python containing a floating point number (e.g. num = 24654.123), and I'd like to determine the number's precision and scale values (in the Oracle sense), so 123.45678 should give me (8,5), 12.76 should give me (4,2), etc. I was first thinking about using the string representation (via str or repr), but those fail for large numbers: >>> num = 1234567890.0987654321 >>> str(num) = 1234567890.1 >>> repr(num) = 1234567890.0987654

• On-demand refresh mode for indexed view (=Materialized views) on SQL Server?

  - by MOLAP

  I know Oracle offers several refreshmode options for their materialized views (on demand, on commit, periodically). Does Microsoft SQLServer offer the same functions for their indexed views? If not, how can I else use indexed views on SQLServer if my purpose is to export data on a daily+ on-demand basis, and want to avoid performance overhead problems? Does a workaround exist?

• Windows RRAS multi-network routing

  - by Brent Pabst

  I am looking for advice, comments and suggestions from anyone who has used Windows RRAS (2008 R2 Pref.) as the primary routers for our multiple offices. We have multiple physical office locations and are looking into utilizing Windows Server 2008 R2 Core as redundant Active/Active routers/gateways for our network as opposed to a physical router from Cisco or Juniper, it costs a lot less! Any problems, issues or documentation anyone would recommend? We will still most likely have a firewall on the edge but the majority of our traffic will be inter-office with some external services. We will be using multiple Class B networks across our two offices.

• Configure Git to use Beyond Compare for image diff

  - by Barney

  Because we work with a number of sprites, the kind of specialised diff views provided by Beyond Compare would be ideal to see which one of 2 versions I'm after when conflicts arise. I've already configured Git to use Beyond Compare as my primary diff and merge tool as described in their integration guide — it specifically goes into how to configure TortoiseSVN to use it for images, and I've found these articles talking about .gitattributes in general and how to script interactions from a *nix shell — but it's not obvious to me how I can use the advice provided by these guides to make a simple change that would say "use the default diff & merge bindings for files determined to be images, too". For the record, I'm doing all this on Windows :P

• Setting up and moving a distribution group to a public folder in Exchange 2003

  - by Sevdarkseed

  I'm looking for some advice with something that seems simple but I haven't done before. Currently we use a distribution group called Orders that has an email address that is that forwarded to four people in the company, the same goes for another one, Quotes. The problem is, of course, no one knows what was answered, and all the email gets worked in to the individual user's emails, so I'm thinking that a public folder, only accessible by one department would be the answer. I'm not sure what the best way to set this up would be or how to move/convert the current distribution list over to a public folder. This is a very critical email address in the company, so I'm trying to be sure that there is zero down time at all for it. What would be the best way to go about creating a public folder and converting/forwarding/moving/(whatever) over the current email address to that folder?

• Apache CPU usage stays at 100% even when there are no requests

  - by Leirith

  Hi, I've been running the Apache HTTP server benchmarking tool (ab) on my new Apache server to test performance. I noticed that with a command like the following: ab -n 100000 -c 1000 http://www.mysite.com/ The CPU is used 100% by the apache2 processes during the testing. When the test concludes, usually with the following error just before the last requests are made: apr_poll: The timeout specified has expired (70007) Total of 99960 requests completed the CPU usage remains at 100%, and it's all being consumed by apache. I am using the worker MPM with and running PHP with mod_fcgid. Any advice as to why this is or what can be done to stop it would be appreciated.

• Script to restart BlackBerry services

  - by ICTdesk.net

  Can somebody give me a script advice/example of how to restart services? I have to restart 17 services, but the first 4 services have to be in the right order and after the restart command is given to one of the services, the next one should be started when the previous one is finished. I know I can restart a service by net command, and I can build a delay by for example a ping command that repeats for an x amount of times, but I never know in advance how long it is going to take for a service to restart. Thanks, Kindest regards, Marcel

• How to design a data model that deals with (real) contracts?

  - by Geoffrey

  I was looking for some advice on designing a data model for contract administration. The general life cycle of a contract is thus: Contract is created and in a "draft" state. It is viewable internally and changes may be made. Contract goes out to vendor, status is set to "pending" Contract is rejected by vendor. At this state, nothing can be done to the contract. No statuses may be added to the collection. Contract is accepted by vendor. At this state, nothing can be done to the contract. No statuses may be added to the collection. I obviously want to avoid a situation where the contract is accepted and, say, the amount is changed. Here are my classes: [EnforceNoChangesAfterDraftState] public class VendorContract { public virtual Vendor Vendor { get; set; } public virtual decimal Amount { get; set; } public virtual VendorContact VendorContact { get; set; } public virtual string CreatedBy { get; set; } public virtual DateTime CreatedOn { get; set; } public virtual FileStore Contract { get; set; } public virtual IList<VendorContractStatus> ContractStatus { get; set; } } [EnforceCorrectWorkflow] public class VendorContractStatus { public virtual VendorContract VendorContract { get; set; } public virtual FileStore ExecutedDocument { get; set; } public virtual string Status { get; set; } public virtual string Reason { get; set; } public virtual string CreatedBy { get; set; } public virtual DateTime CreatedOn { get; set; } } I've omitted the filestore class, which is basically a key/value lookup to find the document based on its guid. The VendorContractStatus is mapped as a many-to-one in Nhibernate. I then use a custom validator as described here. If anything but draft is returned in the VendorContractStatus collection, no changes are allowed. Furthermore the VendorContractStatus must follow the correct workflow (you can add a rejected after a pending, but you can't add anything else to the collection if a reject or accepted exists, etc.). All sounds alright? Well a colleague has argued that we should simply add an "IsDraft" bool property to VendorContract and not accept updates if IsDraft is false. Then we should setup a method inside of VendorContractStatus for updating the status, if something gets added after a draft, it sets the IsDraft property of VendorContract to false. I do not like this as it feels like I'm dirtying up the POCOs and adding logic that should persist in the validation area, that no rules should really exist in these classes and they shouldn't be aware of their states. Any thoughts on this and what is the better practice from a DDD perspective? From my view, if in the future we want more complex rules, my way will be more maintainable over the long run. Say we have contracts over a certain amount to be approved by a manager. I would think it would be better to have a one-to-one mapping with a VendorContractApproval class, rather than adding IsApproved properties, but that's just speculation. This might be splitting hairs, but this is the first real gritty enterprise software project we've done. Any advice would be appreciated!

• WIN32 services dependencies

  - by grmbl

  I know this has been handled before but I'm not getting a clear answer from this question. I have a service that depends on the print spooler.Every now and then, the spooler crashes...(luckily not often)... I need to stop that service when the spooler service crashes. I'm not sure if adding dependency for Spooler to my service will do just that? I tried using recovery option "Run Program" and use some script to stop the service but I don't fully trust that... (getting "Access Denied" errors) Thank you for your advice.

• SQL Insert into ... values ( SELECT ... FROM ... )

  - by Shadow_x99

  I am trying to insert into a table using the input from another table. Although this is entirely feasible for many database engines, I always seem to struggle to remember the correct syntax for the SQL-Engine of the day (MySQL, Oracle, SQLServer, Informix, DB2). I've been wondering if there is a silver-bullet syntax coming from an SQL Standards (For example, SQL92) that would allow me to insert the values without worrying about the underlying database.
