  • supervisord failed to start nagiosapi after reboot, need to run reload manually

    - by Bajingan Keparat
    I have supervisord to start nagiosapi everytime the server starts. The API created a status dump file called status.dat, which will get updated periodically. The following is the conf file that starts the api. [program:nagapi] directory = /home/nagapi user = api command = /bin/bash -c "source /home/nagapi/.virtualenvs/nagapi/bin/activate; /home/nagapi/nagios-api/nagios-api" stdout_logfile = /home/nagapi/supervisor_nagios-api_stdout.log stderr_logfile = /home/nagapi/supervisor_nagios-api_stderr.log Everytime i restart the server, supervisord cannot start the api. stderr.log claims that it cannot find the status.dat file located in /var/cache/nagios3. It seems like the files was not created yet when supervisor tried to run the api the first time. I'm saying this because if i do a supervisorctl reload, everything would reload just fine, and the api would run ok about 50 seconds after the reload command completes. should i change the command option of the conf file to check for

  • Redirect some URL requests to CloudFront and the rest direct to the normal server?

    - by indiehacker
    Say I have two types of URL requests that must be handled by my REST API: http://query.restapi.com/image.png?apikey=abc123 http://query.restapi.com/2.0/<apiKey>/resource.json?from=umi.us_census00.state_geometry Is it possible to redirect only some URL requests for static images (ie., regex: *.png?.*) to take advantage of CloudFront's caching and have the rest of the requests go directly to the normal EC2 server (or at least take a speedier indirect route to the normal EC2 server?). Perhaps the added request time for the misses to CloudFront is irrelevant to worry about? Or perhaps my situation is not best to use for CloudFront? I understand I will need to make DNS change where the current URL requests having http://query.restapi.com/some.png?apikey=0123 get redirected to http://d1234.cloudfront.net/some.png, but I am hoping there is some way for just redirecting static .png requests to take advantage of CloudFront?

  • Allow users to view Word documents only and not be able to edit, copy or save them.

    - by Alexander
    Hello In a traditional Windows Server 2003 environment with AD, we have shared a folder for our policy documents (MS Word). These documents get edited/updated now and then by the administrator(principal of college). Users only have read-only access to the folder, but they can still save-as and then change the content. Sharepoint is a possible solution but not easy to implement. We also thought of using a CMS on Linux and installing Joomla to let users only view the docs with a document management system... but is it possible to automatically retrieve the policy folder on the network and convert or put it in a format that users can only view and not copy? We also thought of saving the docs to secure pdf format but the principal wants an automated system. Basically she just wants to work in Word and the policies must be available to staff members on the network. Any ideas? Much appreciated.

  • Linux - How to manage the password of root?

    - by Jonathan Rioux
    We have just deployed a couple of Linux server. Each sysadmin will have his own account on the server (i.e.: jsmith), and will connect using SSH with a certificate which will be put into the "authorized_keys" file in their home directory. Once connected on the server, if they want to issue an elevated command, they will do like: sudo ifconfig They will then enter the root password. What I would like to know now are the best practices in managing that root password. Should I change it periodicaly? And how do I share that new password with the sysadmins? **Of course I will disable the root logon in SSH.

  • The application attempted to perform an operation not allowed by the security policy

    - by user16521
    I ran this command on the server that has the share of code that my local IIS site set to (Via UNC to that share): http://support.microsoft.com/kb/320268 Drive:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\caspol.exe -m -ag 1 -url "file:////\\computername\sharename\*" FullTrust -exclusive on (obviously I replaced Drive with C, and the actual computername and sharename with the one I'm sharing out). But when I run the ASP.NET site, I am still getting this runtime exception: Description: The application attempted to perform an operation not allowed by the security policy. To grant this application the required permission please contact your system administrator or change the application's trust level in the configuration file. Exception Details: System.Security.SecurityException: Request for the permission of type 'System.Web.AspNetHostingPermission, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.

  • VMware Workstation on Linux: Dropping core files in a shared folder...

    - by kclittle
    I'm using VMware 6.0.2 on a RHEL 4.6 host. The VMs are MontaVista CGE 5.0 (2.6.21 kernel). I'm trying to get applications running in the VMs to drop any core files on a HGFS volume, i.e. in a "shared folder". The core files get created as per the path and format given in /proc/sys/kernel/core_pattern, but they are always zero length. If I change the path to a local path (on a virtual disk in the VM), all is well. Any ideas what I have to do get the core files written into a shared folder? Thanks for your help!

  • Is there any way to disable certain keyboard shortcuts in Windows 7?

    - by matt b
    There is something going on with my Windows 7 machine where attempting to unlock the workstation the Win key is "stuck" on (not quite sure what is causing this). What this causes is that when I am entering my password, which contains a "p", Windows thinks I am pressing Win + p as if I want to change my display settings to enable a projector. This is highly annoying when attempting to unlock my workstation! The workaround I've found to "unstick" the Win key is to cycle through the projector/display settings once, land back on the original value, and then resume entering my password as normal. But is there any way to completely disable the shortcut for Win + p ? In all likelihood I will never hook up a projector to this machine, or on the once-in-a-lifetime chance that I do, I am more than happy with having to go into the Display Settings myself.

  • Is there a free ftp client that has macros

    - by wheresrhys
    At the moment I'm using filezilla to deploy new versions of a site to the live server. the trouble is that there are one or two config, bootstrap etc. files which are different for the live site and I have to be careful not to overwrite. Also there are big areas of code that never change (eg I use the zend framework, which is always the same). I'd like to be able to record a macro to upload the same bunch of files and folders every time, excluding subdirectories and files which shouldn't be overwritten. Does any ftp client offer this?

  • IMCEMAILTO and exghost

    - by Steve
    One of my associates sent an email to me that was also sent to a client. The client's email address appears to be mangled, however. He says he sent it twice---the first one bounced and the second did not. The email address he sent it to was: [email protected] My searches on Google indicate that the MAILTO could be a bad protocol but I didn't know how the email address would be interpreted by exchange server. What email address was the email sent to, how did IMCEMAILTO get there, and does it have any change of getting delivered?

  • Connecting to a VirtualBox machine from the host, using an ip address

    - by Doron
    Hello, In a macbook host, I run VirtualBox having a guest ubuntu server, with a NAT network setting. In the virtual machine application "Parallels", I would get on the host an IP address of the guest, to which I could later set hostnames and access it directly. However, I couldn't find a way to accomplish this using VirtualBox. The only solution VirtualBox has for me, is to set port forwarding, and access "localhost" with these ports. How can I have the desired behavior set up, without having to change to a bridged network settings, and expose my guest computer to the network my host computer is connected to ? Thanks.

  • Volume size doesn't match Disk size after gparted expansion

    - by Cybersylum
    I just expanded a basic disk on a Windows XP VM from 15gb to 40 gb using GPARTED LiveCD (0.5.2-11). I didn't notice anything unusual during the expansion; but after I rebooted back into Windows, the disk capacity doesn't match the disk size as it should (only 1 volume on the disk). The disk shows as 40gb; but the C: volume still shows the original size. I've tried expanding the disk again with GPARTED (no change), and using VMware converter and have it adjust the size of the volume during the process (complains about a lack of space of snapshot error inside the os). The volume has 27% free space so I don't think it is a space issue. Chkdsk doesn't seem to find anything wrong either. The OS seems to run just fine, it doesn't see the additional space however. Any ideas?

  • How to recover data from software RAID 5 disk partition

    - by Ali n
    I have CentOS 5.8 on my computer, with 5x 1TB hard drives. I used software RAID. (RAID 1 as a boot partition md0, RAID 0 as a root partition md1 and RAID 5 as /home partition md3). Unfortunately one of these hard drives failed lately and I want to replace it with a new one. I want to know that is it possible to change this hard drive without data loss? The important partition is RAID 5 so in theory if one of hard drives failed I should be able to recover its data without any problem. But in practice how can I do that?

  • Use Windows Briefcase from the command line

    - by Daniel
    I have a thumb drive on which I take many of my files with me. I would like to synchronize it with my computer automatically when I connect it. I currently have a script run every time I connect it so that I can do the many things that need to be done when it connects (check for updates to the portable applications, etc.). I want my synchronization utility to: Detect conflicts work correctly when I move files or change the folder structure tell the difference between a file that was deleted on one side and a file that was added on the other work from the command line or at least have a command that will open up a window provide a confirmation screen before doing anything The Windows Briefcase does all of these except the command line. Is there any program that does all of these, or is there a way to synchronize the briefcase from the command line?

  • UDP multicast streaming of media content over WIFI

    - by sajad
    I am using vlc to stream media content over wireless network in scenario like this (from content streamer to stream receiver client): The bandwidth of wireless network is 54 Mb/s and UDP stream's required bandwidth is only 4 Mb/s; however there is trouble in receiving media stream and quality of playing specifically in multicast mode; means I can play the stream but it has jitter and does not play smoothly. In uni-cast I can stream up to 5 media streams correctly, but in multicast mode there is problem with streaming just one media! However when I stream from client some multicast streams; the wifi access-point can receive data correctly and I can see the video in "udp streamer" side correctly even when number of multicast streams increases to 9; But as you see I want to stream from streaming server and receive media in client size. Is this a typical problem of streaming real-time contents over wireless networks? Is it necessary to change configurations of my WIFI switch or it is just a software trouble? thank you

  • Microsoft Outlook tips and tricks for improving user experience?

    - by Roee Adler
    I'm one of those heavy Microsoft Outlook users, currently working on the 2007 version. God knows this tool is heavy and may impose problems. I wondered what the Super User crowd has to suggest in order to improve the usage experience. Several suggestions of my own: Always work in cached mode (Tools--Account Settings--Change--Use Cached Exchange Mode) Use Outlook's local archiving capabilities Use Outlook's RSS reader - it's simple and allows offline access to your feeds If you have e-mail subscriptions to magazines, blogs, etc. - create a subdirectory to keep them, and a rule to automatically move them there when they arrive (one rule per subscription, based on the sender e-mail.) You can also share suggestions that require configuration of Exchange Server, for those of us who can make bring them to their IT managers. What are your suggestions? PS: "Use Gmail" is not an accepted answer, some of us don't control what email system we use...

  • How to stop mouse "pausing".

    - by Xavierjazz
    My Microsoft mouse recently stopped working, so I purchased an AOpen O-35G, plug and play. No software came with it and I was advised to "just plug it in". I did this, and it worked, although some of the more advanced features do not work. My problem is that now the mouse cursor hesitates occasionally, and then over shoots the target I selected. This never happened before. It seems to happen when I am using the mouse and a browser window reloads. Does anyone know how to change this? It is very annoying. XP Pro SP3 Thanks. EDIT: It is not a problem of dust or a hair. I have contacted the Manufacturere and they are not responding. I have the mouse attached to my computer via a powered USB hub. I am going to try plugging it in directly to see if that makes a difference.

  • How to determine most stable Cisco IOS release?

    - by Chris J
    This post is about a Catalyst 4948E switch. I was looking on the download page and realized that there are no "GD" versions available. Are the "ED" versions stable? Even if you change "ED" to "GD" in the URL the IOS images are still the same. http://www.cisco.com/cisco/software/release.html?mdfid=283027810&flowid=3592&softwareid=280805680&release=15.1.1-SG2&relind=AVAILABLE&rellifecycle=ED&reltype=latest Is 15.1 as reliable as 15.0? My devices are currently on the 12.2 train. Is there anything special to upgrade to one of the 15.x trains? Are the configurations compatible.

  • Chassis fans and power LEDs still work in Hibernate

    - by Jaded
    I have ASRock Z68 Extreme3 Gen3 motherboard recently updated to 2.20 BIOS version. OS is Windows 7 x64. The problem is after that update full hibernation (by that i mean full system power off) stopped working although everything was fine before. Now when I press hibernate, sleep in initiated as usual, monitor goes to sleep, HDD and CPU fan stop spinning, but chassis fans (i have Gigabyte Aurora 3D 570 case with two rear and one front fans) still remain working. Also power leds are lit as if computer is turned on. Tried changing different UEFI settings related to sleep mode, and none of them change above described behaviour. I have "Deep Sleep" (Advanced-South Bridge Configuration) set to "Enabled in S4-S5", "Suspend to RAM" (Advanced-ACPI Configuration) set to "Auto", all fans settings in "H/W Monitor" set to "Auto".

  • RHEL kickstart with external DVDrom drive

    - by AndyM
    HI I've an old Dell poweredge server with an CDROM drive. I've attached a USB DVDROM and USB stick with my ks.cfg on so I can install RHEL from DVD not loads of CDs :-) I can boot from the RHEL media in DVDROM and point the installer to the USB ks.cfg. This works but the ks.cfg script has the cdrom keyword in it. The install then stops and asks for the RHEL media to be in the CDROM drive not the DVDROM. How can I change the ks.cfg so it uses the external DVDROM for the install media not servers builtin cdrom drive ? I know I can go and rebuild my DVD image to include the ks.cfg , but this is an extra step I dont want to do if I have to. Regards Andy

  • Specifying a source in puppet doesn't seem to work

    - by Mr Wilde
    I have been attempting to create a manifest for installing postgres 9.1 using puppet on a Centos 5 server. I have been trying to adapt the instructions at http://wiki.postgresql.org/wiki/YUM_Installation in order to achieve this and when I go through a manual process, I have been able to. It would seem to me therefore that a puppet manifest containing package { 'postgresql91-server': ensure => installed, source => 'http://yum.postgresql.org/9.1/redhat/rhel-5-x86_64/pgdg-centos91-9.1-4.noarch.rpm' } however on attempting to apply this manifest I get err: /Stage[main]//Package[postgresql91-server]/ensure: change from absent to present failed: Could not find package postgresql91-server Any expert puppeteers out there able to help me?

  • Mass remove passwords from rar archives

    - by ldigas
    Is there a way to (I'm using WinRAR; demo, but I'm willing to change it to whatever is needed) mass remove passwords from a bunch of files ? Problem description: for reasons unknown to me, some archiving was done for two-and-something years in RAR format, and all archives have passwords. I have a list of them, them all being similar (mostly something like John-03, John-04, John-05 ... e.g. name-month ...) but I need to manipulate the files at large, and it is a real problem removing and or dearchiving all those files, while entering passwords manually. What would be my best options concerning ? Ideally, I'm looking for some kind of archiver which tries out a predefined list of passwords, and asks only if non of them cracks the safe. Afaik, WinRAR has no such feature.

  • Security of BitLocker with no PIN from WinPE?

    - by Scott Bussinger
    Say you have a computer with the system drive encrypted by BitLocker and you're not using a PIN so the computer will boot up unattended. What happens if an attacker boots the system up into the Windows Preinstallation Environment? Will they have access to the encrypted drive? Does it change if you have a TPM vs. using only a USB startup key? What I'm trying to determine is whether the TPM / USB startup key is usable without booting from the original operating system. In other words, if you're using a USB startup key and the machine is rebooted normally then the data would still be protected unless an attacker was able to log in. But what if the hacker just boots the server into a Windows Preinstallation Environment with the USB startup key plugged in? Would they then have access to the data? Or would that require the recovery key? Ideally the recovery key would be required when booted like this, but I haven't seen this documented anywhere.

  • IE Sessions in Terminal Server

    - by Jacob
    Currently we are using WADE middleware for our order processing operation. We have about 40 operators that use 1 terminal server to open IE 8 to access the WADE middleware. To me, it's random, but every now and then someone will come to me and tell me that IE has a "Page cannot be displayed" or "HTTP Error 500" error. I did a bit of testing on my local machine and I never get this error while doing normal operations. Although, when I open one session with username "test" and then login to the wade admin console as admin, I run into problems. I do not run into problems until I logout of the wade admin. Once I logout of the Wade admin, my "test" session says "page cannot be displayed". This makes me think the IE user sessions on the terminal service are cross talking. Does anyone have any possible settings I can change in IE or do you think this is an issue with the middleware? The Terminal Server is Windows 2003, btw.
