• Displaying Nagios on a 52" 1080p screen

  - by gdm

  I'm using a 52" 1080p LCD screen to monitor Nagios, positioned where most of the users can see it. Using the default Nagios web view sort of sucks, since you need to increase the text size a decent amount so it's legible from a distance, and then the "Current Network Status", "Host Status Totals", and other boxes along the top take up the majority of the screen realestate; you can't really see the list of host details. Is there a custom view for Nagios, or a plugin, or something available which is meant to display Nagios details on a large screen with large text?

• How can Nagios handle non-threshold based plugins?

  - by FliesLikeABrick

  I am writing a Nagios plugin to monitor trends of a certain storage resource utilization (e.g. gradual increases are fine, but an instantaneous/sudden increase or decrease in resource usage may indicate a problem). For what it's worth, it is reviewing the last N entries in an RRD file generated by a custom cacti data source/templates. What is the "right" way to handle Nagios notification config/implementation for this? The problem is that it the plugin would exit as warning/critical for one polling period, but in the next it would be fine (or 3 polling periods later, if I look at 3 polling periods worth of data). I guess the question is: should I just write it in such a way that it will alert for X polling periods, or should I find a way to write it such that manual intervention is required for it to clear (such as logging into the monitoring server or hitting a URL to run a script that submits a passive result)? Your input is appreciated, and if you have any tips for how to implement the latter I'm open to them (I can think of a few ways to possibly implement it)

• Install latest kernel to Ubuntu and have grub acknowledge the new installed kernel

  - by Phuong Nguyen

  I have an installed Ubuntu Distro (Karmic 9.10) already. However, due to some problems with xorg ati driver, I cannot standby my computer. Some guy have suggested me to try the latest version of xorg driver which in turn requires a newer version of Linux kernel than the newest release available from Ubuntu Central Repository (2.6.33). I have searched though several articles on how to install a custom Linux kernel. However, these articles are so 2004/2005 and they were talking about lilo (???). Since then, I'm afraid that I cannot make the Grub Boot recognize the new Linux kernel properly (I'm just a newbie to Linux). I would love to know how to install the kernel into Ubuntu and have grub acknowledge the new installed kernel.

• How to go about scheduling a task in windows 7 to change wireless connection

  - by Skindeep2366

  This may or not be something that can be done. I cannot find anything on the wireless connection manager built into windows 7 let alone methods for passing params into it. Problem is as follows: I have 2 wireless routers. One provides internet access, the other provides sole access to the local network. Every day at 4am the main system creates a backup in 2 locations. One is a External usb drive, the other is a location on the network. This is all cool if it is remembered to change over to the local network router before leaving. But if it is forgotten the roof will collapse, the walls will burn, and I will be... well you get the idea. Solution: there is already a custom event that fires a automated backup program at 4am everyday. I need someway to force the wireless network to use the correct connection at say 3:58am everyday. Any ideas????

• mount dev, proc, sys in a chroot environment?

  - by Patrick

  I'm trying to create a Linux image with custom picked packages. I followed the guide here http://www.olpcnews.com/forum/index.php?topic=4766.0 However, when I tried to install some packages, it failed to configure due to missing the proc, sys, dev directories. So, I learned from other places that I need to "mount" the host proc, ... directories to my chroot environment. Though, I saw two syntax and am not sure which one to use. In host machine: mount --bind /proc <chroot dir>/proc and another syntax (in chroot envrionment): mount -t proc none /proc Which one should I use, and what are the difference? Edit: What I'm trying to do is to hand craft the packages I'm going to use on an XO laptop, because compiling packages takes really long time on the real XO hardware, if I can build all the packages I need and just flash the image to the XO, I can save time and space.

  - by Blast Raider

  I have noticed that I can only display an uninterrupted period with Cacti.

Thank you.

• Script/ Macro in Excel, by clicking on a cell

  - by Noob Doob

  There's something I want to do in Excel 2010. Specifically, I want to be able to make the open sheet load data from a text file, by clicking -important- on a cell of the current open worksheet. So my specific needs are: If it is possible in some way, to start a macro/script by clicking on a cell. About the script/macro: What would be the preferable, by your opinion, way of implementation. And more specifically, how to automatically import the data needed, only by clicking, without having to continually specify the desirable .txt file each time, only 1 time at max, at start or by using a custom "initalization/configuration" file.

• Cloud services, Public IPs and SIP

  - by Guido N

  I'm trying to run a custom SIP software (which uses JAIN SIP 1.2) on a cloud box. What I'd really like is to have a real public IP aka which is listed by "ifconfig -a" command. This is because atm I don't want to write additional SIP code / add a SIP proxy in order to manage private IP addresses / address translation. I gave Amazon EC2 a go, but as reported here http://stackoverflow.com/questions/10013549/sip-and-ec2-elastic-ips it's not fit for purpose (they do a 1:1 NAT translation between the private IP of the box and its Elastic IP). Does anyone know of a cloud service that provides real static public IP addresses?

• Apache configuration to accept all data

  - by ServerDown

  Hi, I have apache running on port 7979 to talk with a device that sends data to webserver and later will run php scripts to process and send reply xml. The problem now is that it sends data like POST HTTP/1.1 Content-Type:text/xml Content-Length:369 Followed by XML When apache sees this it gives a 400 error. Since the device cannot be changed is there any way to accept the full data sent from the device and write to some log? Currently apache simply keeps sending 400 errors back. If there was a way to log the entire xml or create some custom handler for 400 error then the xml could be read by a php script. Looking forward to solutions.

• HP Rapid Deployment - Change Data Store Path

  - by David Carreyette

  I am running HP Rapid Deployment (Altiris eXpress Deployment Server 6.9 - Build 164) on an inherited Windows Server 2003 SP2. I need to change the Data Store Path as the default is pointing to the C: drive and there is not enough space there. I would like to set it to the D: drive where there is plenty of space. Reading the documentation: Data store path: Specifies the path to stored packages and files and other DS functions (such as license verification). The default path is C:\Program files\Altiris\express\Deployment Server. Note: Do not use this setting to change the path to the Deployment Share. Modifying this setting does not automatically allow you to use another shared directory other than the express share. To change the Deployment Share shared directory, run a Custom install to establish another location for the Deployment Share. Is there any other way I can change the path as I do not have the install media?

• Linux file permissions not being preserved

  - by yellavon

  I am deploying some custom software as root (a necessity for this situation). I set the owner/group to user1:user1 and set all the files to 644 beforehand in shell, then copy and deploy with ant. However, when files get copied over from the deployment directory, the ownership changes back to root and all the files install with 666 permissions. This seems to occur whether the file is overwritten or newly created. I believe there is a way to set an option in cp, mv commands to preserve permissions, but that would be a lot of commands to change. How can I fix this? Is there some setting I can change temporarily for root so the install always preserves the file permissions?

• How can I add leading zeros between delimiters in Excel 2010

  - by Gregory Biernacki

  I am trying to convert a list of property id numbers that has a standard format of 0000-A-00000-00-00, where my worksheet has the various combinations of 1-A-123 10-B-1234 Ideally they would read as follows 0001-A-00123-0000-00 0010-B-01234-0000-00 I've tried using the custom number formatting but it doesn't like the letter in the middle of the number. I didn't know if my only option was to break them apart and then put them back together again. I would accept a solution that merely put the leading zeros at the front of the number, (max is 4 characters) so the result could look like 0001-A-123

• What is the easiest way to get XtraDB for MySQL running on CentOS 5

  - by Jeremy Clarke

  I'm having a lot of issues with a dedicated MySQL server and it seems like upgrading to the XtraDB version of InnoDB will probably have a positive effect, but I'm hesitant to get involved with it since I am not really a sysadmin and prefer to stick with things that start with "yum update". What is the easiest way to get XtraDB installed? Should I use the Percona server? MariaDB? OurDelta? Is there a way to avoid using custom RPMs and sticking to a repo instead? The current yum version of MySQL is 5.0.xx, whereas a lot of the alternate MySQL builds are based on 5.1.xx. How does this factor in? Do I need to figure out 5.1 on CentOS before working on getting XtraDB in? For bonus points: Do I need to seriously test XtraDB with my server before implementing it, or is it relatively safe to have the brief downtime for switching servers followed by putting the site back online with XtraDB?

• Plesk Backup Best Practices?

  - by The MYYN

  My client utilizes Plesk (9.X) for Server Management. We're implementing a custom backup solution, which should include a complete restorable representation of the actual Plesk configuration (Emails, Domains, etc.). We have full access, since it is a dedicated server resembling these steps: Plesk offers some backups, but they do not include the actual content of the (sub-)domains. Browsing the docs and the internet, I haven't found much ideas on that problem. Our target is to have a disaster recovery scenario: Reinstall a clean OS (Ubuntu) from scratch. Install MySQL/PHP and dependencies (since this runs the app) Install a bare plesk Restore all domains + plesk configuration from an archive Continue operations ... Now steps 1, 2, 3 and 5 are trivial. But what are the best practices for step 4? A side questions: Are there any easy-to-use open source apps out there, to create and restore server-images (even on machines with an possible different hardware)? Thanks for your time and input.

• Choosing A Power Supply [closed]

  - by Geeks On Hugs

  Possible Duplicate: Power Supply Capacity Formula How can I check if my system needs more PSU power? I'm not sure if it's OK or not to ask a hardware question here. If not please let me know a good place but I've always got good info here so I thought I'd give it a shot. I'm custom building a new workstation for coding (Linux/Eclipse). How do I determine how much power the power supply needs? I'm building a mini ITX system on a budget and so I need to get as small as possible that is sufficient. I'll have a mini itx mobo with on board wifi and bluetooth, 8 GB RAM, an Intel i3 3.1 Ghz processor, 64 GB SSD and a slim optical drive. In the future I might add a descrete GPU, 16 GB RAM, 128 GB SSD. What is the minimum power I need and how do I calculate that?

• Nxlog Multiline Input to 1 Syslog Message

  - by Eric

  I am using nxlog to tail a custom log file on one of my Windows servers. Each entry in the text file looks similar to this. =================================================================================================================== 1/14/2014 3:08:48 PM DOMAIN\user1 adding group member... Domain: blah Group: TestGroup Member: CN=Joe Bob,CN=Users,DC=blah,DC=ARG,DC=com 1/14/2014 3:08:48 PM 1 member added.<br> ================================================================================================ I'm trying to send this log to my syslog server and I want to combine these multiple lines to 1 line so I can easily grep/search for specific users or groups. I've read some of the documentation on nxlog's website regarding multiline but haven't found a specific config to put them all in 1 entry with a syslog header. Thanks, Eric

• Code deploy system [closed]

  - by Turnaev Evgeny

  Currently we deploy code to servers in a various ways: freebsd package freebsd ports part of config files and static just svn up'ed and a symlink is changed to new upped folder The distribution of freebsd packages to target servers is done through custom tool that uses ssh. I am looking for a code deploy system that will allow: deploy several packages (freebsd or linux) atomic (ether deploy all or none of them to server) can save a history of last stable version - so in case of bad deploy i can easily rollback to last working version all servers ease deployment of config and static files - and integrate those into atomic deploy/rollback system. should work with freebsd or linux (apt-get system)

• putty pageant - forget keys after period of inactivity

  - by pQd

  in the environment where windows client computers are used to run putty to connect to multiple linux servers i'm considering moving away from password based authentication and using public/private key pairs with pass-phrases. using ssh-agent would be nice, but at the same time i'd like it to 'forget' the pass-phrases after given period of inactivity. it seems that putty's pageant does not provide such feature; what would you suggest as alternative? solutions that i'm considering: patching pageant code [might be tricky, code is probably quite rusty and project - sadly - stagnant] writing small custom application using GetLastInputInfo and killing pageant if the machine was idle for more than let's say 15 minutes [ yes, there'll be separate policy for locking the desktops as well ] using alternative ssh client and ssh agent. any suggestions? thanks!

• FTP restrict user access to a specific folder

  - by Mahdi Ghiasi

  I have created a FTP Site inside IIS 7.5 panel. Now I have access to whole site using administrator username and password. Now, I want to let my friend access a specific folder of that FTP site. (for example, this path: \some\folder\accessible\) I can't create a whole new FTP Site for this purpose, since it says the port is being used by another website. How to create an account for my friend to have access to just an specific folder? P.S: I have read about User Isolation feature of IIS 7.5, but I couldn't find how to create a user just for FTP and set it to a custom path.

• How can i automatically move files based on their name?

  - by Pasha

  I have 13 folders containing scanned photographs. Some photographs have been renamed to the date on which they were taken, resulting in YYYY.MM.DD.tif name. It could potentially be YYYY.MM.DD (###).tif where ### is just a number. Others are just named IMG_###.tif I would like to move the files with the YYYY.MM.DD name to a YYYY\MM\DD folder structure. While the files are being moved, I would also like to append the original folder name to the end of the file name. So, a file 01\2012.06.26 (1).tif should end up 2012\06\26\2012.06.26 (1) - 01.tif Is there a Windows tool that can help me with this? Or do I need to resort to writing a custom app?

• How can I launch RemoteApp on Windows Server from server itself at startup

  - by Rusted

  I have Windows Server 2008 R2 with RDS and custom desktop (GUI) application installed on the server. The app is started as RemoteApp on server by user from his desktop computer (or, sometimes, he can work from notebook over VPN). Some details about environment: the server automatically shuts down every evening and automatically power-on every morning (this is a requirement) desktop application do some precalculations/precaching on startup and it can take lot of time mentioned application have some memory leaks, so I can't use hibernate instead of shutdown When user launching this app from his computer, he can't start work with it until this app finishes pre-initialization. Is there any way to start RemoteApp session at the server startup (without actual user logon), so that the user could connect to this session from his computer later? I don't want to involve the user's computer to make it work. I have tried to do it by Windows startup script, but have no luck - starting RDP session requires actual user session.

• How to set up Mac Os X like dragging behaviour on Linux

  - by ticking

  I would like to use Linux(Fedora) on a Aluminum MacBook Pro, but since the Touchpad on a MacBook Pro is only a giant button Apple does some custom tracking. When there is one finger placed, and a second follows (the click can occur before or after that) it will be interpreted as a drag. So the strong thumb can be used to hold pressure and the more accurate index finger can do the pointing. But Linux interprets this as a right click, since it only cares if two fingers are on the pad. Is there a way to achieve said behaviour? Cheers Jan

• Vacation sends autoreply message to the recipient as well

  - by elitalon

  Hi, I have configured my Postfix server with vacation for a domain. Sending a message to [email protected] causes two events: The message is delivered to the recipient ([email protected]) An auto-reply message is sent to the sender, alerting that [email protected] should be used instead. Everything works well except for one particular drawback: the auto-reply is also sent to the recipient, so it receives two messages in the end. What can I do to avoid that? I'm only using the $TO variable in the custom vacation.msg message. And here is Postfix's master.cf vacation line: autoreply unix - n n - - pipe flags=Rhu user=vacation argv=/usr/bin/vacation -j -m /home/vacation/.vacation.msg -f /home/vacation/.vacation.db vacation I know using the -j is a little bit risky according to man page, but I'm kind of testing here.

• How to prevent Spell checking code in MS Office?

  - by Aaron

  We use MS Office. Outlook for emails, Word for some documentation and I use OneNote a lot for my own note taking. What bugs me is when I drop some code or use key words or even camel case into these apps the spell checking picks them up and I have red squiggles everywhere. Ignore is pretty much useless, so either I have to turn off Spell Check altogether start adding these to the custom dictionary. What would be good is if I can use the Set Language function to mark a whole block of text to just not be spell checked. Has anyone found a nice solution to this or do you know of a blank dictionary is best to use? I found using "Mohawk" kind of does that... might just use that for now. Maybe create a macro to switch between them.
