  • What does the -R flag do for chflags?

    - by ralphthemagician
    I'm not clear on exactly what the -R flag does for chflags. I was wondering if someone might be able to help me. The man page says this: Recurse: Change the file flags of file hierarchies rooted in the files instead of just the files themselves. I don't understand what that means. Can someone tell me what the difference would be between chflags -R hidden and just chflags hidden? There's an online man page here for reference: http://ss64.com/osx/chflags.html

  • Is the Cloud ready for an Enterprise Java web application? Seeking a JEE hosting advice.

    - by Jakub Holý
    Greetings to all the smart people around here! I'd like to ask whether it is feasible or a good idea at all to deploy a Java enterprise web application to a Cloud such as Amazon EC2. More exactly, I'm looking for infrastructure options for an application that shall handle few hundred users with long but neither CPU nor memory intensive sessions. I'm considering dedicated servers, virtual private servers (VPSs) and EC2. I've noticed that there is a project called JBoss Cloud so people are working on enabling such a deployment, on the other hand it doesn't seem to be mature yet and I'm not sure that the cloud is ready for this kind of applications, which differs from the typical cloud-based applications like Twitter. Would you recommend to deploy it to the cloud? What are the pros and cons? The application is a Java EE 5 web application whose main function is to enable users to compose their own customized Product by combining the available Parts. It uses stateless and stateful session beans and JPA for persistence of entities to a RDBMS and fetches information about Parts from the company's inventory system via a web service. Aside of external users it's used also by few internal ones, who are authenticated against the company's LDAP. The application should handle around 300-400 concurrent users building their product and should be reasonably scalable and available though these qualities are only of a medium importance at this stage. I've proposed an architecture consisting of a firewall (FW) and load balancer supporting sticky sessions and https (in the Cloud this would be replaced with EC2's Elastic Load Balancing service and FW on the app. servers, in a physical architecture the load-balancer would be a HW), then two physical clustered application servers combined with web servers (so that if one fails, a user doesn't loose his/her long built product) and finally a database server. The DB server would need a slave backup instance that can replace the master instance if it fails. This should provide reasonable availability and fault tolerance and provide good scalability as long as a single RDBMS can keep with the load, which should be OK for quite a while because most of the operations are done in the memory using a stateful bean and only occasionally stored or retrieved from the DB and the amount of data is low too. A problematic part could be the dependency on the remote inventory system webservice but with good caching of its outputs in the application it should be OK too. Unfortunately I've only vague idea of the system resources (memory size, number and speed of CPUs/cores) that such an "average Java EE application" for few hundred users needs. My rough and mostly unfounded estimate based on actual Amazon offerings is that 1.7GB and a single, 2-core "modern CPU" with speed around 2.5GHz (the High-CPU Medium Instance) should be sufficient for any of the two application servers (since we can handle higher load by provisioning more of them). Alternatively I would consider using the Large instance (64b, 7.5GB RAM, 2 cores at 1GHz) So my question is whether such a deployment to the cloud is technically and financially feasible or whether dedicated/VPS servers would be a better option and whether there are some real-world experiences with something similar. Thank you very much! /Jakub Holy PS: I've found the JBoss EAP in a Cloud Case Study that shows that it is possible to deploy a real-world Java EE application to the EC2 cloud but unfortunately there're no details regarding topology, instance types, or anything :-(

  • Apache/Jboss Issue - is this connection timeout?

    - by user115391
    We have an application. The architecture is as below 1 load balancer (apache), which redirects to 2 app servers (jboss). The site is working fine and I am able to access it fine. But sometimes, randomly the homepage takes a while (like 30-40 secs) to load. I tried checking the logs but could not figure out why. I used the httptraffic analyzer, fiddler to see the traffic, but it just says the request/response took 30 secs or so. I checked the apache access logs, mod_jk.log. My configurations are below mod-jk.conf LoadModule jk_module modules/mod_jk.so JkWorkersFile conf/workers.properties JkLogFile logs/mod_jk.log #JkLogLevel info #JkLogLevel debug JkLogLevel error # Select the log format JkLogStampFormat "[%a %b %d %H:%M:%S %Y]" JkOptions +ForwardKeySize +ForwardURICompatUnparsed -ForwardDirectories JkRequestLogFormat "%w %V %T %P %{tid}P %D" JkMount /__application__/* loadbalancer JkUnMount /__application__/images/* loadbalancer <VirtualHost *:8080 > JkMountFile conf/uriworkermap.properties </VirtualHost> JkShmFile run/jk.shm <Location /jkstatus> JkMount status Order deny,allow Deny from all Allow from 127.0.0.1 </Location> ----------------------------- uriworkermap.properties Simple worker configuration file # Mount the Servlet context to the ajp13 worker /=loadbalancer /*=loadbalancer ----------------------------- workers.properties worker.list=loadbalancer,status worker.template.port=8009 worker.template.type=ajp13 worker.template.lbfactor=1 worker.template.prepost_timeout=10000 worker.template.connect_timeout=10000 worker.template.ping_mode=A worker.worker1.reference=worker.template worker.worker1.host=hostname1 worker.worker2.reference=worker.template worker.worker2.host=hostname2 worker.loadbalancer.type=lb worker.loadbalancer.balance_workers=worker1,worker2 worker.status.type=status ----------------------------- my jboss server.xml - $JBOSS_HOME/server/default/deploy/jbossweb.sar/server.xml --------------------------------- The logs from access log is below The issue where it took time - look at the seconds column [23/Mar/2012:12:10:38 -0400] "GET / HTTP/1.1" 200 138 x.x.x.x - - [23/Mar/2012:12:10:49 -0400] "GET /index.jsp HTTP/1.1" 302 - x.x.x.x - - [23/Mar/2012:12:11:10 -0400] "GET /home.jsp HTTP/1.1" 200 936 x.x.x.x - - [23/Mar/2012:12:11:31 -0400] "POST /login/ HTTP/1.1" 200 8895 x.x.x.x - - [23/Mar/2012:12:11:52 -0400] "GET /login/includes/login-style.css HTTP/1.1" 304 - The one after the issue x.x.x.x - - [23/Mar/2012:12:12:18 -0400] "GET / HTTP/1.1" 200 138 x.x.x.x - - [23/Mar/2012:12:12:18 -0400] "GET /index.jsp HTTP/1.1" 302 - x.x.x.x - - [23/Mar/2012:12:12:18 -0400] "GET /home.jsp HTTP/1.1" 200 936 x.x.x.x - - [23/Mar/2012:12:12:18 -0400] "POST /login/ HTTP/1.1" 200 8895 x.x.x.x - - [23/Mar/2012:12:12:18 -0400] "GET /login/includes/login-style.css HTTP/1.1" 304 - Would it be a cache or timeout issue?

  • Deleting jobs from Job History on Xerox Workcentre Pro 123

    - by JPaget
    How do you delete one or more fax jobs from the Job History on a Xerox Workcentre Pro 123? The Xerox Workcentre Pro 123 is a combination copier, printer, scanner and fax machine, and it keeps a history of the numbers dialed for sending faxes, including any long distance access codes that were dialed. In order to keep these access codes private, I'd like to remove these jobs from the job history, or alternatively clear the entire job history. Unfortunately the User Guide and the Quick Reference Guide don't explain how to do this.

    - by Wil
    I was just looking through the Intel site and I came across this - http://ark.intel.com/ProductCollection.aspx?familyID=28398 Anyone know why the 9400 has a tick in the embedded column? I have tried to contact Intel and not had a response. I have looked around but cannot find any additional reference and it seems to be available from shops just like any other CPU. Anyone have any ideas?

  • SSH: How to change value in config file in one command

    - by Brian Graham
    How can I change the value of, let's say, PasswordAuthentication in /etc/ssh/sshd_config in commands? As well, remove a # in front of the "key" I wish to value. These don't all have to be in one command. I setup quite a few servers, and remembering where everything is gets exhausting, so I want to get a series of commands I can copy paste and it does the work for me for future reference. Sample values: PermitRootLogin no ChallengeResponseAuthentication no PasswordAuthentication no UsePAM no UseDNS no

  • web services access not being reached thru the web browser

    - by Tony
    I am trying to reference my .asmx webservices in .NET but my server is not exposed to the internet. When I put on the following address I get the message mentioned below. What's the reason for not being able to see the directory? Am I missing something in my IIS configuraction? Am I missing anything in my permissions? Just as reference I have other folders with webservices and I have the same issue. When I login to the server I am doing it with my windows user and password (I am using windows authentication). It's necessary to mention that when I put the URL I am getting a popup screen to put in my userid and password but it seems that's not able to validate since keeps asking me a couple of times. Let me know if you need more information to address this issue . http://appsvr02/Inetpub/wwwroot/DevWebApi/ Internet Explorer cannot display the webpage What you can try: It appears you are connected to the Internet, but you might want to try to reconnect to the Internet. Retype the address. Go back to the previous page. Most likely causes: •You are not connected to the Internet. •The website is encountering problems. •There might be a typing error in the address. More information This problem can be caused by a variety of issues, including: •Internet connectivity has been lost. •The website is temporarily unavailable. •The Domain Name Server (DNS) is not reachable. •The Domain Name Server (DNS) does not have a listing for the website's domain. •If this is an HTTPS (secure) address, click tools, click Internet Options, click Advanced, and check to be sure the SSL and TLS protocols are enabled under the security section. For offline users You can still view subscribed feeds and some recently viewed webpages. To view subscribed feeds 1.Click the Favorites Center button , click Feeds, and then click the feed you want to view. To view recently visited webpages (might not work on all pages) 1.Click Tools , and then click Work Offline. 2.Click the Favorites Center button , click History, and then click the page you want to view.

  • Using /etc/services for in-house well-known ports

    - by LavaScornedOven
    I couldn't find anything much about this, but I'm interested what are pros and cons (if any) in using /etc/services for in-house software? On my Linux distro (Ubuntu 14.04) at the end of /etc/services is a comment: # Local services hinting that it could be a good thing to do. One thing that comes to mind is that having in-house ports in /etc/services would make serv database a reference point for common knowledge and much better source of default ports for applications throughout the system.

  • Screen is greyed out after power failure shutdown: Mac OSX

    - by Don MacLachlan
    When the battery power is down and the unit not plugged in the computer is forced into a sleep mode requiring pushing the start button when power is re-connected. The initial desktop screen appears to be greyed out and is unresponsive with a timer bar which, when the timing sequence is complete restores an active desktop. I can't find any reference to this phenomenon in the OSX literature I have. Any pointers to where I can get more information? Perhaps I am using the wrong search criteria?

  • Remote installing an msi on citrix servers using WMI

    - by capn
    OK, I'm a C# programmer that is trying to streamline the deployment of a custom windows form app I inherited and built an installer for with WiX (this app will need to be reinstalled regularly as I'm making changes to it). I'm not really used to admin type things (or vbs, or WMI, or terminal servers, or Citrix, and even WiX and MSI are not things I usually deal with) but so far I put together some vbs and have an end goal in mind. The msi does work, and I've installed it from the mapped O: drive on my dev machine and while RDP'd to a citrix machine. End Goal: Deploy code written on my dev machine and compiled into an MSI (that I can improve upon within the confines of WiX and whatever the Windows Installer Engine allows) to the cluster of Citrix machines my users have access to. What am I missing in my script to get the MSI to execute on the remote machines? Layout: Machine A is my dev machine, and has the vbs script and the msi file (XP SP3) Machines C1 - C6 are the Citrix Servers that need the application installed them via the msi (Server 2003 R2 SP2) There is also optionally a shared network resource that all the machines can access. Script: 'Set WMI Constants Const wbemImpersonationLevelImpersonate = 3 Const wbemAuthenticationLevelPktPrivacy = 6 'Set whether this is installing to the debug Citrix Servers Const isDebug = true 'Set MSI location 'Network location yields error 1619 (This installation package could not be opened.) msiLocation = "\\255.255.255.255\odrive\Citrix Deployment\Setup.msi" 'Directory on machine A yields error 3 (file not found) 'msiLocation = "C:\Temp\Deploy\Setup.msi" 'Mapped network drive (on both machines) yield error 3 (file not found) 'msiLocation = "O:\Citrix Deployment\Setup.msi" 'Set login information strDomain = "MyDomain" Wscript.StdOut.Write "user name:" strUser = Wscript.StdIn.ReadLine Set objPassword = CreateObject("ScriptPW.Password") Wscript.StdOut.Write "password:" strPassword = objPassword.GetPassword() 'Names of Citrix Servers Dim citrixServerArray If isDebug Then citrixServerArray = array("C4") Else 'citrixServerArray = array("C1","C2","C3","C5","C6") End If 'Loop through each Citrix Server For Each citrixServer in citrixServerArray 'Login to remote computer Set objLocator = CreateObject("WbemScripting.SWbemLocator") Set objWMIService = objLocator.ConnectServer(citrixServer, _ "root\cimv2", _ strUser, _ strPassword, _ "MS_409", _ "ntlmdomain:" + strDomain) 'Set Remote Impersonation level objWMIService.Security_.ImpersonationLevel = wbemImpersonationLevelImpersonate objWMIService.Security_.AuthenticationLevel = wbemAuthenticationLevelPktPrivacy 'Reference to a process on the machine Dim objProcess : Set objProcess = objWMIService.Get("Win32_Process") 'Change user to install for terminal services errReturn = objProcess.Create _ ("cmd.exe /c change user /install", Null, Null, intProcessID) WScript.Echo errReturn 'Install MSI here 'Reference to a product on the machine Set objSoftware = objWMIService.Get("Win32_Product") 'All users set in option parameter, I'm led to believe that the third parameter is actually ignored 'http://www.webmasterkb.com/Uwe/Forum.aspx/vbscript/2433/Installing-programs-with-VbScript errReturn = objSoftware.Install(msiLocation,"ALLUSERS=2 REBOOT=ReallySuppress",True) Wscript.Echo errReturn 'Change user back to execute errReturn = objProcess.Create _ ("cmd.exe /c change user /execute", Null, Null, intProcessID) WScript.Echo errReturn Next I also tried using this to install, it doesn't return an error code, but doesn't install the msi either, and it makes me wonder if the change user /install command is even really working. errReturn = objProcess.Create _ ("cmd.exe /c msiexec /i ""O:\Citrix Deployment\Setup.msi"" /quiet") Wscript.Echo errReturn

  • Can I set a default domain for a Windows Authenticated website in IIS7?

    - by Michael Haren
    I have an intranet site using Windows Authentication. When users are prompted for credentials, they enter: User: domain\username Pass: SomePassword It'd be nice if they could leave off the domain\ part which would be filled in with a default domain. I'm willing to give up the ability to login with a server/machine account (non-domain) because we don't use that anyway. This seems to be possible with BasicAuth but I can't seem to find a reference for how to do it with WindowsAuth.

  • Photoshop: HSL Color picker plugin?

    Is there a plugin that can let Photoshop use a HSL color picker, rather than HSV (which Adobe calls HSB)? In other words, any/all of the following locations could have an HSL option: Or perhaps a plugin with it's own color picker. Reference RGB HSL HSV (aka HSB) ============= =============== ================ (1, 0, 0 ) ( 0°, 1, 0.5 ) ( 0°, 1, 1 ) (0.5, 1, 0.5) (120°, 1, 0.75) (120°, 0.5, 1 ) (0, 0, 0.5) (240°, 1, 0.25) (240°, 1, 0.5)

    We are running Exchange 2007 with a mix of Outlook 2003 and Outlook 2007. Is it possible to set the Out of Office Assistant so that when OoO is enabled, it sends a reply to every single email the user receives? Also, is there something I can reference that covers the options for OoO such as length of time between replies, etc.? Thanks!

  • FreeBSD - customizing packages

    - by Walter White
    Hi all, I am experimenting with FreeBSD and have used Gentoo in the past. In Gentoo, we have make.conf where we can specify global use flags, and /etc/portage/package.use for package-specific use flags. I found a reference indicating that if you want to customize ports in FreeBSD, you have to pass them on the command-line meaning you will lose those customizations if you forget or simply by doing updates. Any ideas? Walter

  • Does the Noctua NH-U12-DX 1366 cooling system mount on Asus P6T 1366?

    - by Andrea Ambu
    The Noctua NH-U12-DX 1366 is an aftermarket CPU cooler for LGA1366 Xeon CPUs. On Noctua's site they state: Caution: The NH-U12DX 1366 can only be used on mainboards that have a backplate with screw threads for CPU cooler installation (such as the Intel reference backplate for Xeon 5500). The cooler is thus incompatible with Xeon 3500 and Core i7 mainboards that don’t have such a backplate. How do I know if the Asus P6T has this backplate?

  • Availability of downloadable DNSBL dumps?

    - by mtah
    I need to cross-reference data involving a large number of IP addresses against known public proxies, spam-listed IPs etc. For obvious performance and network load reasons, obtaining a regularly updated dump for off-line processing would be preferrable. I currently use http://www.dnsbl.manitu.net/download/nixspam-ip.dump.gz - a digest of ix.dnsbl.manitu.net with 40,000 entries updated every 15 minutes. I'd like something more substantial though, so my question is: does such a thing exist?

  • Proper Imaging Procedures to Restore and Deploy Image with Separate System Reserved Partition

    - by alharaka
    UPDATE: As per my experience here, no one responded. If I do not hear back from TechNet forum members about it, I will post a bounty here, if it makes a difference. I have banged my head against a wall for what seems like all week. I am going to explain my simple procedure, and how none of it, absolutely none, seems to work afterword despite few alternatives and everyone on the internet telling assuming this is how to do it. Diskpart Commands to Create FS Structure REM Select the disk targeted for deployment. REM REM NOTE: Usually disk 0, but drive failure can make it external USB REM media. This will erase the drive regardless! select disk 0 REM Remove previous formatting. clean REM Create System Reserved partition bootloader and files. create partition primary size=100 REM Format the volume format fs=ntfs label="System Reserved" quick override noerr REM Assign the System Reserved partition the D: mount for now assign letter=C REM The main system partition, size not specified to occupy whole drive. create partition primary REM Format the volume format fs=ntfs quick override noerr REM Assign the OS partition the D: mount for now assign letter=D REM Make this the active/bootable partition. sel disk 0 sel partition 1 active REM Close out the diskpart session. exit Now, I thought this was madness, but it turns out the System Reserved partition and standard "System Partition" (C:, commonly both the boot and system volumes where you find the Windows directory AND the bootmgr/ntldr hardware files, this is where Windows 7 diverges) as mounted in the Windows PE session where I run these commands do not matter. See reference here. Since this needs to be BitLocker-ready, enter this crappy System Reserved partition that is separate 100MB of awesome that goes before the regular boot volume. I do this, then I proceed to the next step. Deploy System Reserved and Normal System Images REM C is still the "System Reserved Partition", and the image is just like it sounds. imagex /apply G:\images\systemreserved.wim 1 C: REM D is now what will be the C: system partition on reboot, supposedly. imagex /apply G:\images\testimage.wim 1 D: Reboot the system Now, the images I just captured should look good. This is not even sysprepped, but reapplying the same fscking image I prepared on the same reference workstation hours before. Problem is I get 0xc000000e could not detect the accessible boot device \Windows\system32\winload.exe or different kinds of nonsense revolving around being able to find the boot volume with all the right files. I try different variations of things, now none of them work. I tried repairs with bcdboot, with a fresh System Reserved partition or not, bootrec, and maually editing the damn BCD store with bcdedit. I tried finalizing the above process with and without bootsect /nt60 C: /force. I need to wrap up and automate this procedure. What am I doing wrong that does not make the image happy, but really just miserable.
