• Mono Project: How to install Mono framework on Red Hat Linux which is compiled on centOS ?

  - by funwithcoding

  We have Red Hat Enterprise Linux servers at work place. However we dont have Red Hat Linux desktops. So I used CentOS 5.4 to compile the Mono sources and generated the Mono framework for CentOS and tested with some sample codes and I am satisfied. I want to transfer this compiled framework to Red Hat Enterprise Linux 5. How Can I do that? Do I have to compile the Mono framework statically or do I have to copy the linked libraries as well? I am not familiar with linux much. Any help is highly appreciated.

• Cisco asa 5505 locks up / unresponsive

  - by Chris

  We have a cisco asa 5505 that's new (in service for about 2 months) running 7.2(4) software. Every day around 10a it locks up for approx 10 minutes. We're monitoring it via snmp with stg, and snmp doesn't respond during that time. There's no output in the 'show crash' output. Internet connectivity is also dropped. Wondering if anyone else has seen this and what the fix might be. Currently we're looking at upgrading software, but will need memory upgrade for that. We've forced the speed and duplex on the internal and external interfaces, but the problem is still occurring. It's connected on the internal lan to a netgear 724 gige switch.

• Run one virtual machine on a Linux server + standard Linux functions

  - by fistameeny

  Hi, I am looking for a method to setup a Linux server (running Ubuntu Server) that uses Samba for file sharing, as well as hosting a Windows virtual machine (in this case, Windows Small Business Server 2003, which in turn hosts SQL Server Express - Exchange won't be used on this). I would like to have the Linux server serving the files over Samba, and hosting the Virtual Machine. This obviously rules ESXi out as it couldn't do Samba at the same time. What would be the next best solution to give reasonable speed? Vmware Server 2.0, VirtualBox, Xen? There will be 10-15 users accessing the Samba shares and the SQL Express virtual machine. Matt

• SATA Backward compatibility? [closed]

  - by Fladur

  Possible Duplicate: Can I connect a SATA-II hard drive to a SATA-I connection? Hello everyone One of my system is really old, but I still use it, right now, the HDD is and old IDE drive that is starting to fail (I got to many damaged sectors) and I'm planing to replace it. The motherboard supports Serial ATA 1 and I have a real nice offer on a SATA 2 drive, can I use that drive on a SATA 1 interface (obviously with reduced speed) just like a USB 2.0 device on a 1.0 port? Thanks in advance.

• MYSQL TRIGGER LOOP

  - by Lee

  Hey all I am going through the pain stacking process of sorting out someone else code. So I am decided to recreate a new database to sit alongside the old one then to use triggers to transfer data between both tables. Now I have an issue with a it looping IE A trigger on each table to update the other. Once one updates it should update the other but as both tables have triggers it just will loop which will cause an issue. Is their a way to stop this from happening ? Hope this makes sense and hope you can advise.

• Attach and upgrade TFS 2005 databases to a TFS 2008 installation

  - by henriksen

  I have a Windows server 2008 with SQL 2008 and TFS 2008 installed. And I have another box with SQL 2005 and TFS 2005 installed. Does anyone know of a way I can just transfer the databases (or data in another way) from TFS 2005 to TFS 2008. Any data on the 2008 box can be deleted. The machines are not in a domain so all accounts are local. So I'll have to fix that afterwards, but that's managable. Basically, can I attach the databases and run an upgrade command?

• Drive configuration for 5 large databases

  - by Mr. Flibble

  I've got 5 databases, each 300GB, currently on a RAID 5 array consisting of 5 drives. All the databases are used heavily, at the same time, so drive speed is an issue. Would I see better performance if I got rid of the RAID 5 configuration and just put each database on a separate drive? The redundancy provided by RAID 5 is not necessary due to mirroring elsewhere. Will the server then be able to perform reads / writes to different databases drives in parallel? More so at least than when it's in RAID? This is all on Windows 2003 / SQL 2008.

• Unable to mount portable hard drive on Ubuntu

  - by VoY

  My portable hard drive (WD My Passport), which used to work correctly now does not automount on my Ubuntu system. It does work on a Windows machine or even when plugged into WD HD TV, which is a Linux based device. There's one NTFS partition spanning the whole drive. When I plug the disk in, I see the following in dmesg: [269259.504631] usb 1-2.2: new high speed USB device using ehci_hcd and address 20 [269259.604674] usb 1-2.2: configuration #1 chosen from 1 choice However it does not mount in GNOME and I don't see it when I type: sudo fdisk -l Any suggestions why this might be? I repaired the partition using chkdsk on Windows, so the issue is probably not filesystem related.

• Choosing between cloud (Cloudfoundry ) and virtual servers - for developers

  - by Mike Z

  I just came across some articles on how to setup your own cloud using Cloudfoundry and Ubuntu, this got me thinking, choosing our infrastructure, if we want to use our own servers what's the advantage of cloud on virtual servers vs just using virtual servers, VPN? If we now develop for the cloud later if we need help we can quickly move on to a cloud provider, but other than that what's the advantage and disadvantage of private cloud in these areas? speed of development, testing, deployment server management security having an extra layer (cloud) will that have a hit on server performance, how big? any other advantage/disadvantage?

• Cross Domain Scripting Issues & JSONP

  - by DaveDev

  Our Client requires that we supply Widgits for their site. They want to link to us to get Html & the jQuery required to manipulate the Html and do asynchronous requests. I understand that there are cross-domain security limitations that would prevent this from being a possibility, but that some of those limitations are aleviated by using JSONP as the data transfer format. I'm finding it difficult in finding an explanation of what's possible in the context of what I'm trying to achieve. Could somebody please fill me in?

• limit linux background flush (dirty pages)

  - by korkman

  Background flushing in linux happens when either too much written data is pending (adjustable via /proc/sys/vm/dirty_background_ratio) or a timeout for pending writes is reached (/proc/sys/vm/dirty_expire_centisecs). Unless another limit is being hit (/proc/sys/vm/dirty_ratio), more written data may be cached. Further writes will block. In theory, this should create a background process writing out dirty pages without disturbing other processes. In practice, it does disturb any process doing uncached reading or synchronous writing. Badly. This is because the background flush actually writes at 100% device speed and any other device requests at this time will be delayed (because all queues and write-caches on the road are filled). Is there any way to limit the amount of requests per second the flushing process performs, or otherwise effectively prioritize other device I/O?

• .NET Framework 4.0 installation is very slow

  - by Dimitri C.

  On my Windows Vista, it takes a full 12 minutes to install the .NET Framework 4.0. a) Is this normal? b) If not, can something be done about it? The reason I'm concerned about the speed is because it slows down the testing of our product installer considerably. Testing an installer is time consuming already, but this new .NET Framework installer makes it almost undoable. Detail: I did the test on a clean Vista inside a VirtualBox virtual machine. This setup does not show any performance issues in other situations. I tried both dotNetFx40_Full_x86_x64.exe and dotNetFx40_Client_x86_x64.exe. They both take approximately the same time to install.

• Creating a Network link between 2 buildings

  - by Adam

  Hey My company needs to create a network link between two buildings. Currently we have a cat5e network in one building and would like to connect some computers(about 15) in our second building to the main network in the first building. The distance between the two buildings is 30 metres. The 30 metres means going through a wall from the first building. Going through the car park and then through a wall into the other building. We can run any cables through speed ramps and so we do not need to dig up the road! Also the second building does not have an Internet connection and so we have to create some sort of cable link so that they can share our Internet connection. Ideas? Should we just run cat5e? Should we run fibre? Should we run coaxial?

• best way to authenticate and consume web service using phonegap (html5/javascript)

  - by Raiss

  I am going to develop a phonegap application which is pretty simple. I need to implement an authentication and some simple data transfer back and forth to the phone and server. I prefer to use ASP.NET as a web service and our database is MS SQL but I am not sure what approach should I take to create a secure communication between Phonegap App and webservice. The problem with a simple AJAX request is limitation in cross-domain and I’m not sure if JSONP is a good option. I was wondering if someone can tell me what technology I should use in order to make a semi secure connection which works with PhoneGap (html5, javascript ) and .Net webservice. I understand that it’s a general question but I need to know what technology is the best in such a case. thanks

• Program for HID USB Scale

  Hi guys, I'm looking for a program that can read the weight on a USB scale, namely the Pelouze 10lb USB Portable Scale. I thought it would have a virtual COM port driver but instead, it uses HID drivers. I've been searching for a whole month for a program that can help me transfer the reading of the scale to Microsoft Excel. Can someone help me out or point me in the right direction? I am absolutely illiterate to programming. Much gratitude any help given.

• Does it make sense to have more than one UDP Datagram socket on standby? Are "simultaneous" packets

  - by Gubatron

  I'm coding a networking application on Android. I'm thinking of having a single UDP port and Datagram socket that receives all the datagrams that are sent to it and then have different processing queues for these messages. I'm doubting if I should have a second or third UDP socket on standby. Some messages will be very short (100bytes or so), but others will have to transfer files. My concern is, will the Android kernel drop the small messages if it's too busy handling the bigger ones? Update "The latter function calls sock_queue_rcv_skb() (in sock.h), which queues the UDP packet on the socket's receive buffer. If no more space is left on the buffer, the packet is discarded. Filtering also is performed by this function, which calls sk_filter() just like TCP did. Finally, data_ready() is called, and UDP packet reception is completed."

• Monitoring CPU Usage Over the Course of a Day?

  - by bobber205

  Are there any apps I an install on client machines that will generate a report for me what app used what % of the CPU. We have some machines that are running, at times, VERY slowly. The machine will run really poorly then boom, back up to full speed. There isn't usually enough time to check Task Manager real quickly to see what is running, not to mention the majority of the time there are people using the computer that don't know what the Task Manager is. ;) It would be really nice to take a look at some logs and see if, maybe, the anti virus is randomly taking alot of CPU for stretches of time. Or another application. Thanks! EDIT: This is for Windows XP. Sorry for the oversight. :)

• Fedora14 serial console how-to needed

  - by lamba2

  Has anyone ever got a serial console working in fedora 14 ? Is it as simple as adding to grub: serial --unit=0 --speed=38400 terminal --timeout=10 serial console and add to the kernel lines: console=tty0 console=ttyS0,38400 ??? If so, this isn't working for me. I have agetty installed, and im using minicom, although i've heard you can also use "screen /dev/ttyUSB0" on the client side. The /etc/init/serial.conf file suggests it should be working, but nothing. Currently getting no joy from any of this after 2 days. Does anyone know a method that definitely works on fedora 14 ? (no /etc/event.d/ needed or such) edit: Client side im using a null modem cable and usb-serial adaptor.

• Which browsers support Window's Low Integrity level?

  - by Ian Boyd

  Normally i like running ie, but it's rendering speed at high-dpi is poor. More recently i've switched to Chrome, but it does not support high-dpi displays. i'm interested in trying other browsers, but they must support protected mode. Are there any other browsers, besides IE and Chrome, that support Mandatory Integrity Levels (i.e. protected mode)? Browsers that i do know about: Browser Protected Mode High-dpi Aware ============== =============== ============== Internet Explorer Yes Yes Chrome Yes No Firefox No No Opera No No Are there any other? And just as an fyi, the clear, unambiguous, non-argumentative, non-subjective, question is: Are there any browsers, aside from Internet Explorer, available for Windows, that run at the Windows Low Mandatory integrity level, and support high-dpi (i.e. non-96 dpi) displays?

• Openfire scalability question XMPP Server

  - by candoyo

  Hello! Do you guys know how well openfire scales? My users will be using the application to do normal chatting like msn no file transfer for now. We will be using Amazon's EC2 server to run the chat server we would like to support over 1 Million users in total and around 30-50K active users during peak times. Since clustering is now opensource, I though Openfire might be the way to go, how much will it cost for the coherence license or can I bipass that somehow? Also, I wanted to develop plugin for Openfire if we go with it. Any pointers on how to set up a dev env and get going would be helpful too! Thanks ya'all! :)

• Vista: Improving troubleshoot approach skills

  - by Chau

  I'm not a Windows SuperUser, but neither just the regular user. I don't mind browsing the Registry, using Process Explorer, reading the Event logs, (un)installing new drivers and so on, but all this only makes me solve some problems. I tend though to run into problems where these tools aren't enough. Which tools should I learn about to improve my troubleshooting skills in Windows? Currently I'm using Windows Vista x64 (not moved to 7 yet), facing audio/video stuttering problems and I think this is a good place to improve my troubleshooting skills. I know this post is similar to this question, but my machine is only hanging occationally.
