• Guide for installing Zenoss remote SSH monitoring plugin for Ubuntu

  - by normalocity

  I'm trying out Zenoss. I got it to monitor a test machine via SNMP - that was easy enough. Now I want to add another server that is remote, and I want to use the SSH plugin. I've been using this guide, but it skips a few steps for non-RedHat systems. I'm on Ubuntu. The steps I have down so far are: Install alien Convert the .rpm to a .deb file Use dpkg to install teh .deb file My issue: where to get the .rpm file in the first place?

• convert .p7b key to a .pfx

  - by DrStalker

  I have an SSL certificate in .p7b format that I need to convert to .pfx. If I try this through the windows certificate managment the option to expert as a .pfx is disabled. Trying with openssl I have found the following two commands to do the conversion: openssl pkcs7 -print_certs -in certificate.p7b -out certificate.cer openssl pkcs12 -export -in certificate.cer -inkey privateKey.key -out certificate.pfx -certfile CACert.cer but I'm not sure what key to use for teh esecond command, or what certificate CACert.cer refers to. How can I convert this key to .pfx format?

If i try to remote into the machine via ssh i don't get a prompt . when i rebooted the machine i would get a "video cannot be displayed in this mode" screen and no other activity on the box.

• How do I disable alert beeps

  - by wheresrhys

  My HP pavilion laptop is getting pretty old and the speakers no longer work properly. So I've disabled all audio devices, including disabling the light-touch volume controls at boot-up. The one sound still here that I can't get rid of is teh alert beep whenever there's an error. It's annoying at the best of times, but when your laptop has no other sounds at all it's intensly irritating! Nothing I change in the windows settings or in the BIOS seems to have any effect. Any ideas how to switch them off?

• sa account gets locked out frequently

  - by bala

  I have an sql server 2008 installed. there are about 6 databases created and running on this server I often get message like "SA account is locked out" is there any specific reasons for this account being locked out? is there any other place I need to check the reasons ( I checked the eventviwer but could not get much information) Edit: i found this information in teh eventviewer backups. Is this the cause? SQL Server failed to communicate with filter daemon launch service (Windows error: The service cannot be started, either because it is disabled or because it has no enabled devices associated with it. ). Full-Text filter daemon process failed to start. Full-text search functionality will not be available.

• General High-Level Assessment

  - by tcarper

  Guys and Gals, I've been tasked with a doozy of an assignment. The objective is something akin to "laying of hands" on several database servers which work in concert to provide data to various Web, Client-Server and Tablet-Sync'd distributed Client-Server programs. More specifically, I've been asked to come up with a "Maintenance Plan" which includes recommendations for future work to improve these machines' performance/reliability/security/etc. Might there be some good articles on teh interwebs ya'll could point me towards which would give me some good basis to start? Articles describing "These are the top 4 overarching categories and this is how you should proceed when drilling down on each of them" sort-of-thing would be fabulous. The Databases are all SQL 2005, however the compatibility level is 80 and they were originally created with ERwin based on SQL 6.5. The OSs are all Windows Server 2003. Thanks all! Tim

• What is the value/cost of enabling "spread spectrum clocking" on my hard drives?

  - by Stu Thompson

  I'm building up a biggish NAS box (10x WD RE4 2TB SATA RAID10) and ran into some problems. During the course of my research, debugging, investigations, etc, I discovered a jumper on the physical drives labeled "spread spectrum clocking". After some googling about this on teh internets, it seems to be a feature that some suggest (without reference or explanation) enabling in 'a storage configuration' that makes the drive less sussesptable to EMI. But why? I've got three core questions: Why is this feature not enabled by default? What are the actual benefits? Are there any costs?

• Is there a way to backup all my files and replace with 0-byte files with same name?

  - by laggingreflex

  My main drive on laptop keeps filling up so I take a backup on a USB and delete the original files. But then I find myself getting (downloading or getting from someone else) files that I already have backed-up but couldn't recall at the moment. So is there a way I can keep a 0-byte file with the same name as teh backed-up copy so that when I'm asked whether to overwrite the existing file, I can easily choose no knowing I probably have this file already in the backup. EDIT: better yet, replace with a shortcut(.lnk) on the external drive so I can access the files hassle free and not get any errors because of 0-byte files being accidentally opened.

• How to setup Apache 2.2 (prefork) with mod_fcgid to test a C++ application?

  - by skyeagle

  I have written my first fastcgi application (C/C++), and I need to test it to ensure that it is behaving the way I expect it to. I have searched for examples on setting up Apache 2.2. with mod_fcgid, but all of teh tutorials etc I have seen, relate to PHP, Python, Perl etc. Is anyone aware of a resource that shows how I may setup Apache to use mod_fcgid (NOT mod_fastcgi) to test my binary? If no online resource is available (I'd be surprised), then could someone please point out the steps required to do the testing?

• How can I stop Pages from bolding/italicizing ordered list item numbers/letters?

  - by donut

  I'm writing a long, technical document that uses a lot of ordered lists in Pages '09. Often when I bold or italicize the first bit of text I type for a list item it Pages applies the same styling to the letter or number of that list item. It's been doing this for the first 13 pages I've written and now I've found out that I need to undo that. Is there any place to change this behavior or easily fix existing list item numbers/letters that are styled? The only way I've found is to select the whole list item (all of its content) and removing teh styling (un-bolding and un-italicizing) and then going back in and re-applying my stylings to its content. Definitely not ideal.

• Why does MS-DOS tells me I need extended memory and thinks a file is read-only? [closed]

  - by Jake Inc.

  I am running a .COM file on a MS-DOS 6.22 boot USB drive When I run it on my laptop the program works fine but when I run it on my desktop I get error 40 not enough extended memory. When I go to the memory tab in GUI I try to switch none to auto, but I get the error "This file might be read-only". It's not read-only, when I put it on my desktop I change the settings and the new settings are in a .pif I can't run .pif in MS-DOs so I need to Change the .exe not create a .pif. Change the amount of extended memory all files have on my MS-DOS. On my laptop there is no memory tab, the only real difference is my laptop is x64. Thanks for helping but I think teh x64 bit has nothing to do with it I dont eve nthink iits in 64 bit mode because Im using a boot USB. What i need to is listed above, thanks for helping.

• DNS NAmeserver Aname and cname records

  - by David

  Hi - I am inexperienced in the configuration of DNS and have an issue with dominan hosting set up. I have two domains 'www.mydomain1.com' and 'www.mydomain2.com', with mydomain2 pointed at the same place as mydomain1. The domains were passed to me recently by the person who previoulsy controlled them. I have an account with fasthosts in the uk. When I accepted the domains I could not access the DNS settings and enquired with fasthosts as to why. The replied saying 'The delegate hosting option for both domains were enabled and this is the reason why you were unable to find the option to edit the advanced DNS records. I have now disabled the delegate hosting option so you can now edit the advanced DNS records for both domains in your account.' When i log into the fasthost control panel now i can access the DNS controls but both domains have no A Record of Cname record set up. I am concerned that fasthosts have blatted the previous Nameserver entries and set me up on theirs but not added any record. 'www.mydomain1.com' currently still works but 'www.mydomain2.com' does not find the site anymore. i am worried i will lose mydomain1 to as teh dns changes filter through the system. my webhosting is at 'xxx.xxx.xxx.xxx/mydomain1.com/' and this is where I want both domains to point. Any advice would be much appreciated. one thing which is confusing me is that because I am on a shared server I have to put 'xxx.xxx.xxx.xxx/mydomain1.com/' to get to my site rather than just 'xxx.xxx.xxx.xxx'. The form on fasthosts for the aname record only allows an IP to be entered - does it add the mydomain1.com/ onto the end itself? Thanks for any help given - I'm quite worried about this David

• XNA and C# vs the 360's in order processor

  - by Richard Fabian

  Having read this rant, I feel that they're probably right (seeing as the Xenon and the CELL BE are both highly sensitive to branchy and cache ignorant code), but I've heard that people are making games fine with C# too. So, is it true that it's impossible to do anything professional with XNA, or was the poster just missing what makes XNA the killer API for game development? By professional, I don't mean in the sense that you can make money from it, but more in the sense that the more professional games have phsyics models and animation systems that seem outside the reach of a language with such definite barriers to the intrinsics. If I wanted to write a collision system or fluid dynamics engine for my game, I don't feel like C# offers me the chance to do that as the runtime code generator and the lack of intrinsics gets in the way of performance. However, many people seem to be fine working within these constraints, making their successful games but seemingly avoiding any of the problems by omission. I've not noticed any XNA games do anything complex other than what's already provided by the libraries, or handled by shaders. Is this avoidance of the more complex game dynamics because of teh limitations of C#, or just people concentrating on getting it done? In all honesty, I can't believe that AI war can maintain that many units of AI without some data oriented approach, or some dirty C# hacks to make it run better than the standard approach, and I guess that's partly my question too, how have people hacked C# so it's able to do what games coders do naturally with C++?

• How to break the "php is a bad language" paradigm? [closed]

  - by dukeofgaming

  PHP is not a bad language (or at least not as bad as some may suggest). I had teachers that didn't even know PHP was object oriented until I told them. I've had clients that immediately distrust us when we say we are PHP developers and question us for not using chic languages and frameworks such as Django or RoR, or "enterprise and solid" languages such as Java and ASP.NET. Facebook is built on PHP. There are plenty of solid projects that power the web like Joomla and Drupal that are used in the enterprise and governments. There are frameworks and libraries that have some of the best architectures I've seen across all languages (Symfony 2, Doctrine). PHP has the best documentation I've seen and a big community of professionals. PHP has advanced OO features such as reflection, interfaces, let alone that PHP now supports horizontal reuse natively and cleanly through traits. There are bad programmers and script kiddies that give PHP a bad reputation, but power the PHP community at the same time, and because it is so easy to get stuff done PHP you can often do things the wrong way, granted, but why blame the language?. Now, to boil this down to an actual answerable question: what would be a good and solid and short and sweet argument to avoid being frowned upon and stop prejudice in one fell swoop and defend your honor when you say you are a PHP developer?. (free cookie with teh whipped cream to those with empirical evidence of convincing someone —client or other— on the spot) P.S.: We use Symfony, and the code ends being beautiful and maintainable

• How to write code that communicates with an accelerator in the real address space (real mode)?

  - by ysap

  This is a preliminary question for the issue, where I was asked to program a host-accelerator program on an embedded system we are building. The system is comprised of (among the standard peripherals) an ARM core and an accelerator processor. Both processors access the system bus via their bus interfaces, and share the same 32-bit global physical memory space. Both share access to the system's DRAM through the system bus. (The computer concept is similar to Beagleboard/raspberry Pie, but with a specialized accelerator added) The accelerator has its own internal memory (SRAM) which is exposed to the system and occupies a portion of the global address space (as opposed to how a graphics card would talk to teh CPU via a "small" aperture in the system memory space). On the ARM core (the host) we plan on running Ubuntu 12.04. The mode of operation of communicating between the processors should be that the host issues memory transactions on the system bus that are targeted at the accelerator internal memory. As far as my understanding goes, if I write a program for the host that simply writes to the physical address of the accelerator, most chances are that the program will crash due to a segmentation violation. So, I assume that I need some way of communicating with the device in real mode. What is the easiest way to achieve this mode of operation?

• OBIEE Capacity Planning

  - by THE

  I can not even recall how many times I was asked by a customer what size the machine should be bought to run our Software. Unfortunately Tech Support is not even the right address to answer that question, as a purchase decision is closely tied to the answer. Hence, Tech Support has been limited to the answer: "The biggest machine you can afford" . Many Customers were unhappy with that and have tried to get us to be more precise and that causes a lot of explanation and lengthy discussion. In the end no one is wiser or happier.  Therefore I am happy to report that at least for OBIEE the decision has just been made a whole lot easier. Have a look at the note Oracle BI EE 11g Architectural Deployment: Capacity Planning (Doc ID 1323646.1) The document attached to that note gives you a good overview for teh sizing of the machines that Oracle recommends to run OBIEE (be it a small installation or a bigger distributed installation) If you have any more questions about this topic and what machines we recommend, then get in contact with  Oracle Consulting or speak to your sales representative.

• Wrong source IP when accessing internet directly from TMG server

  - by jarod1701

  Hi everyone, after implementing a ForeFront TMG server I'm facing only one problem: After I added a second IP to the external adapter I had to manually set "NAT Address Selection" inside the network rule "Internet Access" to the first IP since all others would get blocked by the CISCO firewall. This configuration works as long as traffic comes from the internal network (e.g. browser on clients). Traffic from the TMG directed to the internet always carries the second IP as it's source address and gets blocked. All our other TMGs/ISAs are running fine and I never came across this problem- Does anybody have a clue, coz I don't?! Kevin

• Why are there unknown URLs in router log?

  - by Martin

  I recently looked at my router log. Why are a lot of requests that I don't send originated from a computer in my home network? They do not look like 3rd-party advertisements / images embedded in a page. The request have patterns, such as: top-visitor.com/look.php www.dottip.com/search/result.php?aff=8755&req=nickelodeon+games www.placeca.com/search/result.php?aff=3778&req=wireless+cell+phone www.bb5a.com/search.php?username=3348&keywords=flights www.blazerbox.com/search.php?username=2341&keywords=colorado+springs+real+estate www.freeautosource.com/search.php?username=sun100&keywords=vehicle www.1sp2.com/search.php?username=20190&keywords=las+the+hotel+vegas www.loadgeo.com/search/result.php?aff=10357&req=winamp www.exalt123.com/portal.php?ref=seo2007 www.7catalogs.com/search.php?username=la24&keywords=shutter www.theloaninstitute.com/search.php?username=kevin&keywords=webcam www.grammt.com/search.php?username=2530&keywords=bob And there are hundreds of these requests send within a second.

• Want 2 external monitors with a 13' MacBook - is this possible?

  - by kevinburke

  I've got a 13' white MacBook from 2008 and I'd like to run one or two external monitors, my budget is $500. I've tried to do research and this is what I was going to get - will these work OK? Two Diamond BVU195 HD USB Display Adapters (DVI and VGA with included DVI to VGA adapter) to plug into the USB port Two Dell ST2310 monitors One external USB hub so I don't use up both of my USB ports Will this work? I've read some people say it does and some people say it doesn't, but I don't know enough to say either way. Also do you have recommendations for a better monitor than the dell sd2310? what's the best setup I can buy for $500? Thanks very much for your help, Kevin

• JBoss basic access

  - by user101024

  I have JBoss 5 deployed on Solaris 10 - the servers connection has unrestricted high ports (1023) open to the internet. I can access the box via ssh & FTP from a second server on the same subnet and anywhere over the internet. JBoss is running over port 8080 and is accessible via http://locahost:8080 on the box itself. I cannot access it via http://ip.add.goes.here:8080 from either the other server on the same subnet or via the internet. Is there any service or configuration within JBoss or elsewhere on Solaris 10 that needs to be changed from default to allow http traffic to be served? Thanks, Kevin
