• Virtual Machines and Automatic Software Updates

  - by Zian Choy

  It's obvious that one's main computer should always be have all the latest security patches and most people don't blink an eye when Microsoft Update installs non-security updates. In the land of virtual machines, I've run into 2 problems with automatic updates: The virtual machines are only run when needed. Only Windows virtual machines seem to patch themselves. To elaborate on #1, I generally make a virtual machine with a purpose in mind. For example, when I needed an old copy of Internet Explorer to reproduce a bug in RSS Bandit, I had a Virtual PC named RSS Bandit. The machine only stayed running for a few minutes at a time. Consequently, there is no downtime for the machine to download updates at 3 AM. To elaborate on #2, I've noticed that if I haven't run a Windows virtual machine in a while, then the moment I log in, the computer frantically downloads updates and within seconds, if I click the Start button, there is a little orange shield next to the "Shutdown" button. However, I ran a freshly created Ubuntu VM for several hours today with hundreds of updates pending and it seemed to never download any of them or install any of them. Is there any reason to be concerned about running VMs with dozens of security holes? If I should be concerned, then is there any way to get Ubuntu to download and install updates rather than just advertising a long list of updates to download next century? I've already tried telling Ubuntu to automatically download and install updates.

• Postgresql server will not start

  - by Claudiu

  I'm on Windows 7. I restarted my computer. I then tried to connect to the database and got an error. I don't remember which one in particular but it was some connection issue. I decided to try to restart the server, so I clicked on "Restart server" from the start menu. This blocked. After a few minutes I killed the process and tried again, only to get a "The service is starting or stopping. Please try again later." message. I rebooted the computer again, tried to start again, and got the same error. I killed the pg_ctl process and tried starting it manually, but that didn't work either: C:\Users\DrClaud>cscript "C:\Program Files\PostgreSQL\8.3\scripts\serverctl.vbs" start wait Microsoft (R) Windows Script Host Version 5.8 Copyright (C) Microsoft Corporation.

• Problem setting command-line console resolution. vbeinfo in grub2 does not report all resolutions

  - by Kent

  I have a Asus EEE PC 1005P which I installed a Command-line system on using the Alternate Installer CD of Ubuntu Lucid Lynx. Altough I think this is a general linux and grub2 question. I do not have (or want) the X Window System installed. I want to change my console screen resolution (not inside X) to 1024x600.

• Grant access for users on a separate domain to SharePoint

  - by Geo Ego

  Hello. I just completed development of a SharePoint site on a virtual server and am currently in the process of granting users from a different domain to the site. The SharePoint domain is SHAREPOINT, and the domain with the users I want to give access to is COMPANY. I have provided them with a link to the site and added them as users via SharePoint, which is all I thought I would need to do. However, when they go to the link, the site shows them a SharePoint error page. In the security event log, I am showing the following: Event Type: Failure Audit Event Source: Security Event Category: Object Access Event ID: 560 Date: 3/18/2010 Time: 11:11:49 AM User: COMPANY\ThisUser Computer: SHAREPOINT Description: Object Open: Object Server: Security Account Manager Object Type: SAM_ALIAS Object Name: DOMAINS\Account\Aliases\00000404 Handle ID: - Operation ID: {0,1719489} Process ID: 416 Image File Name: C:\WINDOWS\system32\lsass.exe Primary User Name: SHAREPOINT$ Primary Domain: COMPANY Primary Logon ID: (0x0,0x3E7) Client User Name: ThisUser Client Domain: PRINTRON Client Logon ID: (0x0,0x1A3BC2) Accesses: AddMember RemoveMember ListMembers ReadInformation Privileges: - Restricted Sid Count: 0 Access Mask: 0xF Then, four of these in a row: Event Type: Failure Audit Event Source: Security Event Category: Object Access Event ID: 560 Date: 3/18/2010 Time: 11:12:08 AM User: NT AUTHORITY\NETWORK SERVICE Computer: SHAREPOINT Description: Object Open: Object Server: SC Manager Object Type: SERVICE OBJECT Object Name: WinHttpAutoProxySvc Handle ID: - Operation ID: {0,1727132} Process ID: 404 Image File Name: C:\WINDOWS\system32\services.exe Primary User Name: SHAREPOINT$ Primary Domain: COMPANY Primary Logon ID: (0x0,0x3E7) Client User Name: NETWORK SERVICE Client Domain: NT AUTHORITY Client Logon ID: (0x0,0x3E4) Accesses: Query status of service Start the service Query information from service Privileges: - Restricted Sid Count: 0 Access Mask: 0x94 Any ideas what permissions I need to grant to the user to get them access to SharePoint?

• Win 7 running slowly with low CPU usage and memory

  - by guywhoneedsahand

  I have a relatively new (under 2 yrs old) windows 7 machine. It has 9GB of RAM, and an i7 core CPU (930 @ 2.8GHz w/ 8 CPUs). After about 8 months since a clean install, I noticed my computer was running slowly. I figure it was fragmentation etc, and I did a complete wipe & clean reinstall. However, my problems are somehow persisting. The computer is running painfully slowly (but in leaps and bounds - sometimes it will work fine for 3 hrs, then suddenly freeze up just from clicking the start button). The 'freezes' happen randomly - not during any especially intensive computing. I initially thought something might be eating through my CPU and/or Memory, but Task Manager indicates that neither the CPU or Memory spike. In fact, even during serious lag, CPU usage remains at less than 5% and Memory at ~ 1.5GB. It's beyond me why a fresh install on a powerful machine is performing so poorly... and it certainly is frustrating! What could be causing the poor performance, and what can I do to fix it?

• Vista ICS issue

  - by Bill Grey

  I have a strange problem with Internet Connection Sharing on a laptop running Vista Business. This laptop is connected to the internet via the ethernet port, which goes to an ADSL modem. it is automatically assigned the IP address 192.168.1.50, and the modem/gateway is 192.168.1.1 My friends laptop is running Vista Home. Previously, I would create an ad hoc wireless network, enable ICS, and everything would be perfect. My friend would have internet access via this. However, something has now mysteriously broken. If I enable ICS on the wireless connection, it resets my Local Area Connection, assigning it the manual IP address of 192.168.0.1, which means my connection to the internet is destroyed. Both wireless adapters on each network are assigned auto configuration addresses, in the 168. range. They can see each other fine, but my friends laptop cannot access the internet via mine, even after I have restored the Local Area Connection settings. I understand the computer with ICS enabled must have the IP of 192.168.0.1, but previously, before whatever went wrong, my wireless adapter would be 192.168.0.1 and my friends computer would get an IP via DHCP. I have also tried setting static IP address and making a bridge, none of which works. How can I fix this problem, and prevent enabling ICS from touching my Local Area Connection? Both machines have no firewall, have appropriate settings etc...

• Error 720 on VPN (PPTP) attempt

  - by Andy Shulman

  When I attempt to connect to a server running XP x64 (so essentially Server 2003) using a PPTP connection, it fails with client-side error Registering your computer on the network... Error 720: A connection to the remote computer could not be established. You might need to change the network settings for this configuration. and server-side error Event ID: 20050 The user WINSERV3\Andy connected to port VPN8-1 has been disconnected because no network protocols were successfully negotiated. I have configured the router to pass both TCP packets on 1723 and GRE packets. I have used Wireshark (filtering out ARP, UDP, and all TCP ports other than 1723) to observe the packets received by the server. Wireshark does not explicitly name any protocol GRE, but it does tell me the server sent and received TCP, PPTP, PPP LCP, PPP CHAP, PPP CBCP, and PPP IPCP. The connection seems to go wrong at packet 30, where the protocol is PPP LCP, with the payload of the packet being labeled "Protocol Reject". Obviously, this is going from server to client. This would seem to lead to the conclusion that there is something wrong with my client, which runs Windows 7 Ultimate x64. However, it is able to connect to my house's router, which runs the DD-WRT firmware and is thus a PPTP endpoint. I'm thoroughly at a loss. Please help!

• IIS 7.5 Siteminder Does not protect ASP.net MVC requests

  - by HariM

  We are trying to use ASP.Net MVC with Siteminder for Single Sign on. This is on Windows Server 2008 R2 with IIS 7.5. Siteminder Agent version 6QMR6. Problem : Siteminder protects physical files that are exist. And it is not protecting the folder when we try to access a non existed file. It must redirect to login page even if the file doesn't exist when the user is accessing a protected folder. How to configure in IIS 7.5 that Do not verify a file exist, before authentication by siteminder. SiteMinderWebAgent is a Handler(WildCard Script Map) we created using the ISAPI6WebAgent.dll How to Protect ASP.Net MVC Request with Siteminder? (Added this as My previous question did not solve the problem). MVC Request shows up in IIS Log but not in Siteminder log. Update : Microsoft Support says currently IIS7.5, even in earlier versions doesnt support wildcard mappings on any two Isapi Handlers with * wild card. Currently in my case Siteminder has * wildcard and asp.net mvc (handler is aspnet_isapi) has * wildcard to handle the reqeusts. Ordered priority doesnt work in the wild card mappings case with Just *. Did not convinced with the answer but will wait till tomorrow for them to get back.

• How to use Windows mini-dump files?

  - by ekaj

  I have a Mini-ITX Intel DH61AG mobo w/ an Intel i3 processor and 8GB of 1600MHz DDR3 RAM. Anyways, this computer has been crashing kind of frequently. It is not an OS problem, as I have used Ubuntu (and had kernel panics), Windows 7, and Windows 8 (BSODs aren't going to keep me from tinkering =p) Anyways, each of these OSes have had problems, so I ran a HDD check, and I know it is not a heat issue because I tested the processor for a few days when I first put the computer together. When I ran memtest86+, however, I got an error - so I did individual testing, and both chips came back good, did a really intense test with both of them again (took half a day), and no errors. So, I still think the problem could be RAM, but I am not sure - I tested it pretty extensively (might let it run all night again tonight)... which brings me to my point. Could someone explain to me (in simple terms if possible) how to READ the minidump files of Windows computers? I've tried before with a guide I found online, but failed miserably (can't remember guide, either =/). I'm fine with installing the software, I will probably need it sometime in the future as well. I have seen a few other posts on SU that just ask people to post minidump logs, but I feel as if that is too localized. Would someone be able to explain this? Note: If someone knows how to do this, but doesn't want to explain and is still willing to help me, this is the link for the minidump file =p Make sure to click

• How could Google Latitude find my exact PC location with no GPS or public wifi?

  - by Mike

  I found a similar question here but I still don't get it. You see, I live in a small town and every time I check my IP location via online services or speed test websites, my location appears to be my ISP server location (which in my case is 250 miles away). But when I tried Google latitude, it pinpointed my exact location within less than 100 meters! I use Windows Vista, Google Chrome, and when I got the message that "Google is trying to locate you", I agreed just to check what the result will be. It was scary, very scary! What I've come up after reading the above link is that Google have a kind of extensive WiFi database locations. That could be understandable with the case of public and open WiFis that are used with a lot of people. Some of them might be using applications that could gather location data and somehow this information ends up in giant Google databases. From those, Google could pinpoint a WiFi location based on its MAC address along with these bits of info that have been gathered via various sources. The issue here is that my WiFi is private, I don't even broadcast my WiFi name. So how on earth did Google find my exact PC location? Please break down the answer in layman's terms as possible.

• iTunes Home Sharing only works one way between 2 WinXP PC's on the same LAN

  - by scunliffe

  Both PC's have the latest iTunes installed. PC (A) can "see" that there is a shared library "B library" but attempts to connect to it return this error message: The shared library "{Username}'s Library" is not responding (-3259) Check that any firewall software running on either the shared computer or this computer has been set to allow communication on port 3689. however the reverse works fine. e.g. PC (B) can "see" shared library "A library" and can access all content. Notes: Both PC's have Home Sharing enabled (turned off/on several times to verify). Both PC's have Windows Firewall turned on, but in the exceptions tab, iTunes is allowed, and Port 3689 is also added as a firewall exception (just in case) Both iTunes accounts have been "authorized" on both PC's Both PC's connect via LAN via D-Link DIR-615 router. In the advanced application rules, iTunes has also been added to allow traffic on port 3689 un-hindered. Is there any other magical setting/configuration option that I should be aware of and set in order to get this to work? I could care less about sharing apps etc. I just want the music sharing to work. Update: Solved! It turns out on PC (B) there were multiple accounts set up. 1 of the accounts had the checkbox checked under the windows firewall "On" option which states "No exceptions" thus even though it was added to the exception list on the main user account, this other account was blocking access.

• Wifi Drops Connections with WPA2-PSK

  - by graf_ignotiev

  I run a small computer lab made up of 10 computers of identical hardware and software (Dell Latitudes with Windows 7 x64 Enterprise) and I use a ZyWALL 2WG as a router/firewall. Nine of the computers connect to the router over wifi using WPA2-PSK encryption while the last one is connected by ethernet cable. I'm having a problem where any computer connected to the wi-fi occasionally drops off the network (it cannot be pinged and the client cannot ping the gateway). It only happens on the wifi side and only when the encryption is WPA2-PSK or WPA-PSK. I tried using another router with a different make and model and had no problems. Thinking it could be a software error, I reset the router to factory defaults and installed the newest firmware (V4.04(AQI.8) | 04/09/2010), but still have the problem. The 802.1X log gives the following error User logout because of user disassociation. with this note WPA2-PSK:00242c582ece:logout where 00242c582ece is the mac address of the device. At this point I'm out of things to try and leads to follow. It looks like this user had the same or similar problem, but none of those proposed solutions work for me.

• How does the EFI partition work and can I boot an x86 OS with a bootx64.efi file?

  - by Ian

  I have a Thinkpad X230 laptop and I want to install Linux Mint Debian Edition along side Windows 7 on my GPT formatted SSD with the BIOS in UEFI mode. The problem is that I don't understand how EFI booting works. There seems to be an EFI partition involved with some folders and binary files in it. GRUB 2 seems to be able to make more folders in it (I followed this guide http://www.thinkwiki.org/wiki/UEFI_Firmware), but it appears that the only file that does anything is the bootx64.efi file in the /efi/boot folder of the EFI partition (I am not sure if this is always the case, but it appears to be the case for my laptop http://www.thinkwiki.org/wiki/Category:X220). Here is what I have been able to do: I can install Linux Mint Debian Edition x86 with the BIOS in BIOS mode on my SSD. I can then install grub-efi and follow the guide linked above. The problem is that I don't get a GRUB prompt when I switch the BIOS to UEFI mode. It just boots Windows. It appears that I can either boot from the SSD or something called "Windows Boot Manager". If I replace the bootx64.efi with the file created by GRUB, I can no longer boot directly from the SSD. Booting from "Windows Boot Manager" still works fine. I realize that the guide says to use x64 Linux, but Linux Mint Debian Edition x64 hangs during the install process. I am really confused. What should I do? Can anyone explain how the EFI boot partition works? Can a bootx64.efi boot an x86 OS? Should I just give up with using UEFI? I haven't been able to find very much useful information about using Debian based operating systems with UEFI. Thanks, Ian

• Fedora-13 not detecting USB HDD enclosure (with HDD)

  - by Ramy

  I recently purchased this enclosure: http://www.amazon.com/Inland-2-5-Inc.../dp/B003SZ2Y12 and this HDD: http://www.amazon.com/Seagate-Barrac...3811667&sr=8-1 Now, I let my brother in law use the enclosure with his 160GB disk to back some stuff up. He then gave me that disk in my enclosure and I backed up my computer and my fiances computer. So...obviously, i had no problem mounting that disk. I plan on keeping this disk as my "natural disaster backup" (in case my apartment building burns down, i still have that disk with my stuff backed up). I want to use the 1.5T disk as my regular/more frequent backup device, but it doesn't seem to be mounting to my F-13 machine. I searched through this forum and found someone advising to run the following: # mount -t vfat /dev/sda1 /mnt this is the output i get when I run that: mount: /dev/sda1 already mounted or /mnt busy mount: according to mtab, /dev/sda1 is mounted on /boot Thing is, shouldn't this disk automatically mount just like the LAST disk in the same enclosure with the same USB cable and power supply? Any help would be greatly appreciated. THANKS!

• Windows 7, network connection with no default gateway: any way to change the "Unknown network" statu

  - by e-t172

  Hi, I have a computer running Windows 7 Pro RTM. This computer has two network connections: A Wi-fi connection to the Internet (through a home router) which works just fine. An OpenVPN virtual network connection. More precisely, this is a virtual Ethernet connection which behaves exactly like a physical Ethernet wired connection. My problem is that the "Network and sharing center" shows "Unknown network" for the OpenVPN connection. After some research I found that logical networks (outside a domain) are identified by the MAC address of the default gateway of the connection. Problem is, the OpenVPN connection has no default gateway: it is a private network, so I don't need one... Consequently, the "Unknown network" is always considered public, so the firewall is always in "public mode", which I don't want. Plus, I can't rename "Unknown connection" or anything (which makes sense), so it is kinda ugly. My goal is to define a proper logical network for the OpenVPN connection with the private profile. I know of some workarounds (disable the firewall, modify security policy to make all unknown networks "private") but they're still workarounds. I just want my clients to connect to the VPN without having to disable their firewall settings, without changing global configuration with potential side-effects (the "security policy" solution) and without having to look at an ugly "Unknown connection" in the Network and sharing center. Is there any way I can do this? I tried to check what was going on in the registry (HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\NetworkList is interesting), but I still didn't find a way to "force" the OpenVPN connection to be assigned to a logical network. Any help would be very appreciated. A related question showed up at Superuser: http://superuser.com/questions/37355/windows-7-cant-identify-network/37422

• Can't connect two PCs to a Network Switch at the same time (Windows 7)

  - by puk

  I have two computers connected to a network switch and every once in a while one of the computers will lose its internet connection. It's almost always the same computer every time. However, if I play around with the control panel, I can switch it, so that now the other computer is not connected. Restarting either of the computers does not help either. In Windows, the worlds-greatest-trouble-shooter tells me that a network cable is unplugged and that I should try plugging it in...Disabling and re-enabling my NIC does not fix this problem, neither does swapping cables around. When rebooting, the BIOS complains about how the Ethernet Cable is not plugged in. If it's in any way important, My set up at the office is like so: Modem - Routher - Network Switch 1 - Network Switch 2. I have tried turning off the energy saving option for my NIC, and I tried manually setting the link-speed to 100Mbps Full Duplex without any luck. Also, I have a Realtek PCIe GBE Family controller on both computers Does anyone have any idea why this is happening every 5-10 days? EDIT: I have also tried using a completely different Network Switch and the problem still persists as before.

• How to utilize 4TB HDD, which is showing up as 2.72TB

  - by mason

  I have two internal HDD's. They're both 4TB capacity. They're both formatted with the GPT partitioning scheme, and they're Basic Discs (not dynamic). I'm on Windows 8 64bit. I have UEFI, not BIOS. When I view the discs in Computer Management MMC with Disk Management, they show that each partition is formatted as NTFS and takes up the entire drive. And it shows that each drive has a capacity of 3725.90GB in the bottom section of Disk Management, but 2.794.39GB in the top section. When I view the discs in "My Computer"/"This PC" they only show up as 2.72TB, which matches the amount capacity I'm getting from some other 3TB HDD's I have. Why are they showing up as only 2.72GB? Will I be able to use the full 4TB capacity? Also of note, although I'm not sure it's relevant: I often get corrupted files on these two HDD's. None of my other HDD's give me corrupted files. Usually the problem is fixed by running chkdsk /f on the drives, but it's extremely annoying. In the picture below, it's the X: and Y: drives. Steps I've tried Flashed latest BIOS (MSI J.90 to K.30)

• Parallel port blocking

  - by asalamon74

  I have a legacy Java program which handles a special card printer by sending binary data to the LPT1 port (no printer driver is involved, the Java program creates the binary stream). The program was working correctly with the client's old computer. The Java program sent all the bytes to the printer and after sending the last byte the program was not blocked. It took an other minute to finish the card printing, but the user was able to continue the work with the program. After changing the client's computer (but not the printer, or the Java program), the program does not finish the task till the card is ready, it is blocked until the last second. It seems to me that LPT1 has a different behavior now than was before. Is it possible to change this in Windows? I've checked BIOS for parallel port settings: The parallel port is set to EPP+ECP (but also tried the other two options: Bidirectional, Output only). Maybe some kind of parallel port buffer is too small? How can I increase it?

• Troubleshooting Mid 2007 iMac RAM upgrade

  - by MDT

  I am trying to install new RAM in my friends iMac, something I have done several times before. We unplugged the computer before performing the upgrade, used anti static wrist bands, and yes the memory is compatible and inserted correctly. The stock RAM was Hynix 1gb pc2-5300s-555-12 and the memory we are replacing it with is 2x2gb Centon CMP800SO2048.01. Now I know this model number suggests that the ram is 800MHz and the iMac is only 667MHz but it clearly states on the box that this RAM is PC2-5300 667MHz compatible. The problem is, that when I install the new RAM I get little response from the computer. I hear the hard drive and disk drive start to initialize, but then they just stop and the screen remains black. I have tried every variation of the new RAM and the old RAM in both slots and even tried the same RAM from my old iMac and I just can't get it to boot. Has anyone ever had a problem like this? Thank you in advance for any and all input on thus issue!

• Get details / solve issue with a kernel panic?

  - by Joseph

  I have a Lenovo T430 running Linux Mint 13 (MATE): joseph:~$ uname -a Linux joseph-T430-LM 3.2.0-23-generic #36-Ubuntu SMP Tue Apr 10 20:39:51 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux I installed Mint immediately after getting the laptop about two weeks ago, and have noticed that about once a day, the computer will completely freeze up- I can't use Ctrl+Alt+Backspace to restart X, I can't use Ctrl+Alt+F1 to get a text only terminal, can't move mouse, can't type, and if any music was playing it just gets stuck in about a 1-second loop. There is a Windows partition, but I haven't had any issues in Windows. I couldn't find a common thread between the freezes, they were seemingly random (sometimes right after I clicked the mouse, sometimes not; sometimes with Pandora/flash being used, sometimes not, etc). I assume they're kernel panics since it completely locks up, but the laptop doesn't have a capslock or scroll lock LED. It is on a dock and I do have a USB keyboard, but the scroll lock/capslock lights do not flash when it happens (not sure if this is indicating its not a kernel panic, or if the kernel panic just wouldn't illuminate the LEDs on a usb keyboard attached to a laptop dock). This was annoying but not terrible. However, I've found a way to reproduce it. I have a particular CSV file that when I open up in LibreOffice Calc and scroll around, the same thing happens- complete lock up. I really need to use this file, so I'd like to fix the issue, but at the least it's given me a test case to work with. So, having a case where I can cause this issue, what can I do to better find out what's going on? I've looked in /var/log/syslog but haven't found anything seemingly useful. Any thoughts?

• I Can Edit SD Card on Windows XP but Not on Windows 7

  - by David C

  I have an 8GB SDHC card which I have used to upload pictures onto my Windows XP machine using an SD card reader ("SanDisk Ultra II"). I could also delete pictures and create folders on the card. I recently obtained a new computer that runs Windows 7 and, while I can view and upload the photos, I am unable to delete photos or create folders. When I attempt to do either of these two operations, the desired option does not appear in the menu ("Delete"/"New Folder"). Also, the shortcut keys do not work (e.g. the Delete key and Alt+F+W+F). I have attempted to change the Properties from Read-only, but am greeted with a "media is write protected". I should add that when I insert the Card Reader back into my Windows XP computer, I am granted full write permissions. Why can't I modify the SD Card from Windows 7? And, related, how can I fix this issue? Let me know if you have any additional questions. Thanks!

• How to collect the performance data of a server during an unreachable/down period using Nagios?

  - by gsc-frank

  Some time services and host stop responding due to a poor server performance. I mean, if for some reason (could be lot of concurrency services access, a expensive backup execution on the server or whatever that consume tons of server resources) a server performance is very degraded, that could lead that the server isn't capable to establish any "normal network communication" (without trigger whatever standards timeouts defined for such communication). Knowing host's performance data (cpu, memory, ...) in case of available during that period (host is not down and despite of its performance degradation still allow plugins collect performance data) could be very useful for sysadmin to try to determine what cause the problem, or at least, if the host performance was good and don't interfered at all in the host/service down. This problem could be solved using remote active (NRPE) or remote passive (NSCA) if such remote solutions could store (buffered) perf data to be send to central Nagios server when host performance or network outage allow it. I read the doc of both solutions and can't find any reference to such buffer mechanism neither what happened in case that NSCA can't reach Nagios server. Any idea of how solve this lack of info? so useful for forensic analysis. EDIT: My questions isn about which tools I can use to debug perf problems or gather perf data to analysis, but is about how collect (using Nagios) host perf data even during a network outage for its posterior analysis (kind of forensic analysis). The idea is integrate such data to Nagios graphers like pnp4nagios and NagiosGrapther. I know that I could install tools like Cacti in each of my host, and have a kind of performance data collection redundancy, but I really want avoid that and try to solve all perf analysis requirements with one tools: Nagios

• Fedora 17 - Dropping into debug shell after attempted partitioning

  - by i.h4d35

  So I tried creating a new partition on Fedora 17 using fdisk as follows: Command (m for help): n Command action e extended p primary partition (1-4) p Partition number (1-4): 1 First cylinder (2048-823215039, default 2048): Using default value 2048 Last cylinder or +size or +sizeM or +sizeK (1-9039, default 9039): +15G Once this was done,instead of formatting the partition I created, I ran the partprobe command to write the changes to the partition table. On rebooting the computer, it drops to the debug shell and gives me the error as follows: dracut warning:unable to process initqueue dracut warning:/dev/disk/by-uuid/vg_mymachine does not exist dropping to debug shell dracut:/# While trying to run fsck on the said partition from the debug shell, it says "etc/fstab not found" and inside /etc I see a fstab.empty file. Is it now possible to retrieve what I have from the computer? Any help would be appreciated. Thanks in advance Edit: I've also tried the following steps for additional troubleshooting: I tried to boot using the Fedora disk and tried the rescue mode - says no Linux partition detected. I tried to create an fstab file by combining the entries from blkid and the /etc/mtab file and using the UUIDs from the mtab file - It didn't work. As soon as I rebooted the machine, it promptly dropped me in to the debug shell and the fstab file which i created wansn't there anymore in /etc (part of this solution)

• Cannot login to Windows7 in normal mode but can in safe mode

  - by Guy

  I have a Windows 7 Ultimate computer (Shuttle) that I built myself and in it I put a Solid State Drive (SSD). It's been working well for a number of months but now when I start it there are problems. I have 2 users setup on the computer and when I try and sign in with either user it claims that the password is incorrect. I could understand the odd typo but I've had my wife try it as well and we've got the passwords correct. On top of that it will remain at the login screen for 1 minute and 20 seconds and then spontaneously reboot without shutting down. So I'm trying to work out if this is a hard disk problem or something else. Any ideas? (I have a nightly backup to a WHS so it will be easy to recover but I don't want to do that unless I have to and don't want to waste time putting in a new HD just to discover it's something else.) More info: If I start in Safe Mode I am able to login with the password and all appears as normal as it can in Safe Mode. However, normal boot continues with same problem.

• Restoring open software after a restart event in windows

  - by Doltknuckle

  I find that at the end of a long day, I sometimes have a large number of programs running. All which I will need to use tomorrow. Normally, this isn't an issue, I can simply lock the machine and come back tomorrow. My problem arrises when windows update launches in the middle of the night and force restarts my computer. That in turns closes all my open software. I of course save everything regularly so I don't loose anything, but I waste time reopening all of those resources whenever there is a restart. [EDIT] I should clarify that I still want to be able to restart my computer when an update comes down. Preventing the restart only delays the problem until later. I should have been more specific in that I want to be able to recover my working environment after a restart for any reason. Things like scheduled maintence, power loss, updates, and software installs. [EDIT] I can't simply have them setup to launch at startup becasuse those files change from week to week. So I need something that monitors what I have open, and gives me the option to "recover" those software sessions when I log back in. Anyone have any suggestions on what I can do? I'd even be willing to purchase software to do this for me if that is the only option. Thanks
