• Anyway to backup nginx before recompiling

  - by JM4

  I am looking to install the HttpGeoipModule for NGINX but learning I have to recompile the entire thing from source in order to do so. I have a new Media Temple DV 4.0 server and that comes with nginx v 1.3.0 stock and have never had to recompile from source before and a bit nervous to make changes without being able to revert to a previous state in the event something messes up (that and the fact it is affecting a live server so no idea what downtime is). My plan was to copy all the existing modules used (nginx -V to list them all and copy the modules already compiled). Then rebuild from source with the copied info above and including the ./configure --with-http_geoip_module reference. Is is possible to backup the existing nginx configuration in the event something goes wrong?

• Migrating Printers from XP to 7 (using USMT 4.0)

  - by Luís Mendes

  I'm attempting to migrate a user from an XP machine to a 7 machine, using USMT 4.0 (User State Migration Tool, from Microsoft). For some reason the migration of printers isn't working, and none of the topics at Microsoft's TechNet are helping me out. I'll list the topics, just for the record: http://social.technet.microsoft.com/Forums/en-US/w7itproinstall/thread/ab8d6d70-9d1b-419c-8149-37387d4eba6d http://social.technet.microsoft.com/Forums/en-US/w7itproinstall/thread/e92d9ce9-ad9f-4ba0-b326-c7ae6dc50a58 There was a suggestion to use a customized XML configuration file, to force the migration printers, but it didn't work as well. They also mention a folder named DIManifests, which has to be present in the USMT directory. I've tried everything, but with no success. Can anyone please help me sort this one out? Apparently it's a bug, but there's gotta be some workaround. Thank you!

• Why does the java -Xmx not working?

  - by Zenofo

  In my Ubuntu 11.10 VPS, Before I run the jar file: # free -m total used free shared buffers cached Mem: 256 5 250 0 0 0 -/+ buffers/cache: 5 250 Swap: 0 0 0 Run a jar file that limited to maximum of 32M memory: java -Xms8m -Xmx32m -jar ./my.jar Now the memory state as follows: # free -m total used free shared buffers cached Mem: 256 155 100 0 0 0 -/+ buffers/cache: 155 100 Swap: 0 0 0 This jar occupied 150M memory. And I can't run any other java command: # java -version Error occurred during initialization of VM Could not reserve enough space for object heap Could not create the Java virtual machine. # java -Xmx8m -version Error occurred during initialization of VM Could not reserve enough space for object heap Could not create the Java virtual machine. I want to know why the -Xmx parameter does not take effect? How can I limit the jar file using the memory?

• Unresponsive virtual OS

  - by confusedGeek

  Hopefully someone has a suggestion on how to resolve this. Configuration Host: Win 2003R2 w/Virtual Server 2005R2 Virtual1: Win 2003R2 w/Sql Server 2005 Virtual2: Win 2003R2 w/WSS 3.0 Situation This past weekend the power went out and took down the servers (no UPS, it's a desktop standing in as dev testing server). Since the servers went down the Virtual2 server after running WSS fairly heavily for an hour to two will become unresponsive via HTTP. If I login via virtual server's remote control I don't get anything beyond a background screen. The CPU counter on the virtual server's master status shows that it isn't doing anything. The only thing I have been able to do is to turn off Virtual2, which loses any state changes. Shutdown commands issue from the virtual server master status are ignored. After restarting Virtual2 the event logs and application logs don't indicate what caused the problem. Anyone have an idea as to how to repair the OS, or maybe what could be the problem? Thanks ahead of time.

• where are the "ipmi sel" entries parameter descriptions?

  - by Horatiu

  In order to troubleshoot a possible hardware issue I have installed ipmitools on my server and am doing queries for info related to poweron/poweroffs, hardware added/removed/status. I am trying to find some info on how to interpret sel obtained via ipmi sel list and the output looks like this : 72b4 | 10/31/2013 | 10:42:40 | System Event #0x01 | OEM System boot event | Asserted 72c8 | 10/31/2013 | 10:42:48 | System ACPI Power State #0x82 | S0/G0: working | Asserted I really want to know what "Asserted" means in this context, and also, where can I find a reference with all possible "exit status(es)" ? (Because I think that's what this is, right ?)

• Why is hibernation still used?

  - by Moses

  I've never quite understood the original purpose of the Hibernation power state in Windows. I understand how it works, what processes take place, and what happens when you boot back up from Hibernate, but I've never truly understood why it's used. With today's technology, most notably with SSDs, RAM and CPUs becoming faster and faster, a cold boot on a clean/efficient Windows installation can be pretty fast (for some people, mere seconds from pushing the power button). Standby is even faster, sometimes instantaneous. Even SATA drives from 5-6 years ago can accomplish these fast boot times. Hibernation seems pointless to me when modern technology is considered, but perhaps there are applications that I'm not considering. What was the original purpose behind hibernation, and why do people still use it? Edit: I rescind my comment about hibernation being obsolete, as it obviously has very practical applications to laptops and mobile PCs, considering the power restrictions. I was mostly referring to hibernation being used on a desktop.

  I'm having an issue regarding a disk imaging process. I have a WinPE image that will re-partition, the hard drive, and put a boot-able image on it. When I run the imaging process from an initial state, I get the following error remove disks or other media press any key to restart If I run the process subsequent times, It will work as desired, but I'm still interested in getting the process to work the first time. How do I figure out what's going on here? what should I be looking at? I'm a little bit out of my depth here, I don't know what to do next

• CentOS: safe to yum reinstall after removing 32-bit packages?

  - by virtualeyes

  as per the CentOS FAQ on removing 32-bit packages present in a 64-bit install, is it safe to perform the last step: You may also want to do this: yum reinstall \* The reason is that sometimes the /usr/share/ items (shared between BOTH packages) get removed when removing the 32-bit RPM packages. on an existing installation? (i.e. where data & settings of possibly affected applications need to be preserved) rpm -Va shows a number of entries like: /sbin/ethtool: at least one of file's dependencies has changed since prelinking S.?..... /sbin/ethtool /usr/libexec/mysqld: at least one of file's dependencies has changed since prelinking S.?..... /usr/libexec/mysqld along with /usr/share entries with T flag (apparently filetime diff, seems safe) The machine is up & running fine, but may not be whenever a reboot occurs. Clue-in as to the real state of the machine (hosed or OK) appreciated Thanks

• Is there an way to get the top level classes included in a puppet node?

  - by pwan

  Is there an easy way to return the top level classes applied to a node. By this I mean the classes included in a node definition or ENC equivalent For example with the sample node below, I'd like to return 'return::me' and 'return::me2' for somehost, but not 'dontreturn::me' class return::me { include dontreturn::me } node "somehost" { include return::me include return::me2 } I see that /var/lib/puppet/state/classes.txt includes the full list of classes applied to the node, but that includes any additional classes included by to the top level classes. Is there some way to get at this data with a puppet faces command ? I suspect 'puppet nodes' might be useful, but I haven't been able to get it return what I what.

• Windows 7 libraries missing from start menu?

  - by Chris L.

  I was trying to stop an annoying error where renaming a new folder in Windows 7 (Starter OEM via Toshiba) would bring up the dreaded "cannot find item" error. I was lead to uninstall Windows update KB980408 with the added registry fix. Well, now the problem is still unfixed, but worse, all the libraries have vanished from the right side of my start menu! This is a pretty aggravating state of affairs, and I've already tried a system restore, adding back in some registry keys, changing preferences...the smash. Funnily enough, libraries are still in explorer and I can see that according to preferences they are displaying, but...nada. Any suggestions?

• How to prevent Windows Home server waking for backup

  - by Andronicus

  Since changing the motherboard in my Windows home server it has been switching itself on every night to perform a scheduled backup. I don't want this to happen though, I want to switch the server on using Wake on lan, but I want to manually perform backups if/when required. I know I can disable backups of each computer, and the machine wont turn on, but I want to allow manually triggered backups, or automatic backups if the homeserver is on, but if its in sleep mode, I wish it to stay in that state unless I wake it. How can this be achieved?

• How do I configure additional phone lines asterisk/trixbox?

  - by Matt

  I have a 4 port Digium card in there, and have 4 lines running smoothly. Now, we added ANOTHER 4 port card and have 4 more analog lines coming into the Trixbox server. It still runs the 4 fine, but what do I need to do to add the additional 4 phone numbers/lines? I want it to act exactly as before, there's nothing special about the new lines. We just need more lines so that when we have 4 out of state customers call, we can have 4 more call and not get the busy signal. Trixbox CE 2.8

• What is the command to use to put your computer to sleep (not hibernate)?

  - by airrick

  I want to put my windows pc (win7) into a sleep state via command line (so i can bind to macro button on keyboard). The power button on the PC is setup to but the computer to sleep (but it's down on the floor and I'm too lazy to reach down) it exactly how I want it (sleeps using hybrid mode in case I loose power) The sleep command on the shutdown menu also works. most info I found says to use; %windir%\system32\rundll32.exe PowrProf.dll, SetSuspendState 0,1,0 But this puts the computer in hibernate mode. I do have hibernate disabled but using hybrid sleep. So, What is the command to use to put your computer to sleep (not hibernate)?

• Debugging an IP Camera

  - by Kevin Boyd

  Further to my previous question on ServerFault here, I finally can view the stream on RTSP however I still cannot view the camera stream in a web browser. The IP camera uses an activeX control in Internet Explorer. And although I can configure the camera settings from IE, I cannot view the stream it shows connecting for a few sec and shows disconnecting. I have forwarded the HTTP, RTSP and Stream ports of the IP camera. the public port is 7071 and private port is 7070. When I try to see the connections in TCPView it shows that the ActiveX control in IE is trying to connect to port 7070 which is quite unusual since it should connect to 7071 Also the state shows SYN_SENT for sometime and then disconnects. I have really no clue what's going on and why?

• excel - merge cells including a zip code

  - by evanmcd

  Hi all, I have the need to merge a bunch of cells that comprise an address (street, city, state, zip) into a single cell. No problem except with the zip code. The zip cell has only 4 digits for any zip that starts with 0. So, I change it's format to be Special - Zip Code. That makes the cell itself show the beginning 0, but the merged cell still does not show the leading 0. Does anyone know how to get the leading 0 in the merged column? Thanks Evan

• Options for transparent data encryption on SQL 2005 and 2008 DBs.

  - by Dan

  Recently, in Massachusetts a law was passed (rather silently) that data containing personally identifiable information, must be encrypted. PII is defined by the state, as containing the residents first and last name, in combination with either, A. SSN B. drivers license or ID card # C. Debit or CC # Due to the nature of the software we make, all of our clients use SQL as the backend. Typically servers will be running SQl2005 Standard or above, sometimes SQL 2008. Almost all client machines use SQL2005 Express. We use replication between client and server. Unfortunately, to get TDE you need to have SQL Enterprise on each machine, which is absolutely not an option. I'm looking for recommendations of products that will encrypt a DB. Right now, I'm not interested in whole disk encryption at all.

• OpenVPN Permission Denied Error

  - by LordCover

  I am setting OpenVPN up, and I'm in the state of adding users. Details: Host System: Windows Server 2003 32-bit. Guest System: Ubuntu Linux (with OpenVPN installed already), actually I downloaded it from OpenVPN.Net. Virtualization: VMWare v7.0 Problem: I can access the Access Server web portal (on the port 5480), but when I login to http://host_ip:943/admin and enter my (correct) login info, it shows me a page saying that "You don't have enough permissions". I am the (root) user!!!! that is really weird!!! Note: if I enter wrong login it will denote an incorrect login, this means that I am logging in successfully but the problem comes after the login process. What I tried: I tried to create another user after (root) logging in to Linux Bash using (useradd) command, but the same resulted.

• Does anyone know why rsync would keep sending the files over and over again?

  - by beagleguy

  I'm trying to using rsync to backup some files, about half a TB. It's now it a state where it keeps sending the same files everytime it runs. for example: rsync -av /data/source/* user@host:/data/dest sending incremental file list source/file1.txt source/file2.txt I then verify those files are copied over... then the next time it runs it does the same thing rsync -av /data/source/* user@host:/data/dest sending incremental file list source/file1.txt source/file2.txt any idea why it's getting stuck on these files? I've tried to wipe the whole dest directory out and start over but no luck. thanks,

• IIS Hangs on SQL Connections when running ASP.net applications

  - by PaulWaldman

  We have a database server running SQL 2000 and two web servers hosting ASP.net applications. All three servers are running Windows Server 2003 SP2. Our issue is repeatable after about 2 weeks, IIS on one web server is no longer able to establish SQL connections. Static content loads fine. Other non-IIS applications are still able to contact the SQL database server. ODBC functionality also still works. While running SQL profiler a connection is never established from IIS when it is in this state. The only way to fix this situation is to restart the web server. There are no firewalls installed on any machines.

• Major permission repair needed on Mac Os

  - by Luke1111

  I made the fatal error of copying and pasting a sudo command into my terminal without double checking it, here it is. sudo -R mysql / What this does (for those that don't know) is recursively change the owner every file from the root down to mysql!! obviously not what i was intending This has of course played havoc with my system, the first thing i did was the apple permission repair but that only works for files that it has an idea of though it has changed a lot of file ownerships back to root. It seems that many library files are still owned incorrectly, as a lot of problems don't work. What i propose doing as a temporary fix until i can reinstall mountain lion is to recursively set all ownerships that are mysql to Luke. I'm not sure what they should precisely but this is still better than nothing. Is this possible using a shell script? I realise that this won't fix the problem properly and i will have to reformat but i need the machine in a workable state just for this week.
