• IT Inventory Tracking

  - by DrStalker

  What is a good tool to keep track of IT inventory? Systems that are installed and running, parts being ordered, that sort of thing. I'd love a central, web based system (preferably something we can customize) but my searching so far has resulted in a lot of dead open source projects that havn't been updated in a few years and poorly created commercial websites that don't do a very good job describing their product. The software doesn't have to be free or open source - a good commercial alternative is fine. It doesn't even need to be a web-based tool, that's just what I thought would be simplist to find and easiest to deploy. The number of assets that it will be tracking will be in the dozens, so it doesn't have to be a super high-end enterprise solution but it does need to do a better job than an excel sheet in a shared folder (which is our current "solution")

• Can I force a workstation to use a specific domain controller?

  - by Chad

  I'm on a domain that I can't control the domain controllers on, but I can control my systems. All the domain controllers are part of one site, and that cannot change. However, one of the domain controllers is not working correctly and the admins in charge of it are taking forever to resolve the issue. There are 6 total domain controllers... for some reason my workstations/servers are still attempting to use the bad one to authenticate my users. Is there a way to force a workstation to use specific domain controllers? or, better yet, force it to NOT use the bad one? Thanks in advance!

• Where to obtain openssl-devel for SunOS 5.10

  - by user35949

  So I am having an issue that I have seen other people have on many different systems. I have to build Subversion on a SunOS 5.10 box and have run into issues. I have the openssl source code installed and in the subversion-1.6.9 folder, I run the following: ./configure --with-ssl --with-libs=/opt/exp/lib/openssl/lib and receive the error: checking for library containing RSA_new... not found configure: error: could not find library containing RSA_new configure failed for neon I have also tried running the command without the "lib" on the end of the --with-libs path. I read online that I need the openssl-devel packages, but I have been unable to find them for SunOS 5.10, and they do not show up already installed on my system when running pkginfo. I have looked online including http://www.sunfreeware.com/ which I was told was a good SunOS software source. Any help you can provide would be welcomed. Thanks, Sean

• Alerting when a RAID Array disk fails locally on VMWare ESX or ESXi System

  - by Tim K

  With ESX and ESXi, we recently had two systems where that the boot partition became degraded due to a failed disk. The only alert we managed to capture was the visual alert on the Dell servers. We failed to received any electronic alerts regarding the failed or degraded array. Does anyone have any experience with monitoring for these types of failures? In both cases, the servers were running in a RAID 5 SCSI configuration (5 disks on one system, 3 disks on another) which if we were running a Windows Server OS, we would have had an alert created in the Eventviewer. Where would I begin to look for this solution. Can it be configured in VCenter or vFoglight?

• How to troubleshoot ping request time out

  - by user28317

  I have a Windows 7 and an XP machine connected to a NETGEAR wireless router. Both machines can log into the network and surf the web. Both are connecting wirelessly. I can ping the router from each machine and get a reply. I can ping each machine from the router and get a reply. But i cannot ping each machine from the other; getting a request time out. Subnet IP Addresses are 192.168.1.* Router =1; Win7 = 10; XP = 11; Firewall is currently off in both systems. Since i can ping from router im picking that not the problem anyway. If i try to ping from xp to win7 i get Request Timed Out. If i try to ping from Win7 to Xp i get destination host unreachable. What should i do now? Thanks

• rkhunter warns of inode change by no file modification date changes

  - by Nicholas Tolley Cottrell

  I have several systems running Centos 6 with rkhunter installed. I have a daily cron running rkhunter and reporting back via email. I very often get reports like: ---------------------- Start Rootkit Hunter Scan ---------------------- Warning: The file properties have changed: File: /sbin/fsck Current inode: 6029384 Stored inode: 6029326 Warning: The file properties have changed: File: /sbin/ip Current inode: 6029506 Stored inode: 6029343 Warning: The file properties have changed: File: /sbin/nologin Current inode: 6029443 Stored inode: 6029531 Warning: The file properties have changed: File: /bin/dmesg Current inode: 13369362 Stored inode: 13369366 From what I understand, rkhunter will usually report a changed hash and/or modification date on the scanned files to, so this leads me to think that there is no real change. My question: is there some other activity on the machine that could make the inode change (running ext4) or is this really yum making regular (~ once a week) changes to these files as part of normal security updates?

• Best technique for reusing a Windows system image across configurations

  - by Martin Wiboe

  We are a small company that provides solutions for ventilation systems. Part of the solution is a "controller" which communicates with the ventilation equipment. These controllers are simply Dell computers that come with our Windows 7 system image on them and sometimes some special hardware. We typically do a batch of 10 controllers at a time. We have been using Norton Ghost to apply the system image, but this process breaks because Dell changes the system configuration often, and our Windows image now does not contain the correct drivers. This is especially a problem when they change the RAID controller. To improve this, I see 2 options: use some kind of virtualization and install a hypervisor on each PC. This would solve the driver problem, but probably cause trouble with our special hardware. use some method of adding the proper drivers to our Windows image in offline mode. I haven't got much experience in either of these approaches. How would you solve our problem?

• How Will Mac OS X Snow Leopard Upgrade Work?

  - by Blaenk

  I am relatively new to Mac OS X. I got my MacBook in January, and I have never experienced a new version of the operating system. I am wondering if I should simply upgrade my install to Snow Leopard. I come from Windows where it is advised to do a complete reformat. I would rather not do this, however, and I have a feeling that due to Mac OS X' POSIX based nature, it might actually not be all that bad if I upgrade. I guess if things end up screwing up I can simply go ahead and reformat, but I am wondering what it is like to upgrade systems running Mac OS X. I wouldn't want my Snow Leopard installation to be somehow deficient due to certain inconsistencies within the system.

• My computer has gone horribly slow, how can I dignose whats wrong?

  - by Chirag N.R.

  I have a computer based on AMD processor & 512 MB RAM. Lately the computer has gone horribly slow. I did many tricks but was of no avail. So, I reinstalled my Operating system - Win XP SP3, still the the response is very slow. I checked if there are any background applications consuming resources. There was nothing suspicious. I removed all the applications on start, still the computer is slow. I've heard that AMD processor based systems show this behavior when they get aged. Is it true? Should I just buy a new system?

• Security and encryption with OpenVPN

  - by Chris Tenet

  The UK government is trying to implement man-in-the-middle attack systems in order to capture header data in all packets. They are also equipping the "black boxes" they will use with technology to see encrypted data (see the Communications Data Bill). I use a VPN to increase my privacy. It uses OpenVPN, which in turn uses the OpenSSL libraries for encrypting data. Will the government be able to see all the data going through the VPN connection? Note: the VPN server is located in Sweden, if that makes a difference.

• 1tera flop cluster?

  - by Adobe

  I want to buy a $40000 1 tera flop cluster to keep it in a room. What are the standard configurations? Cluster is supposed to do molecular dynamics simulations on biological systems. I'm proposed a 4 pc with 8 cores each by the selling company I'm deadling with. It looks like I also need infiniband. Does some one has an experience -- what phisical memory should I buy etc? I know things change very quickly... Still there might be a point or two to state. Edit: OS is supposed to be linux, application is gromacs.

• Help desk software - specific feature needed

  - by LunchMoney

  I am having a hard time finding help desk software that allows for drop down hyperlink selection during ticket creation. The situation is that we do external support for client systems and connect via remotely anywhere or logmein. Right now we use a poorly modified php based system that has a customer drop down menu and then a site drop down list that is then parsed by a bit of java script which opens a url. What I am looking for is the ability to store customer site URL information in the database and during the creation of a ticket be able to select the customer name and then select the site there by placing the corresponding site URL in the ticket. The support tech will then be able to click on this link to access the customer's site. Has anyone used or seen help desk software with this feature?

• Update saved password for basic authentication using a script

  - by Kalamane

  I have a website that uses basic authentication as described on this webpage. Each of the computers I manage have the password saved in their browser. There is only one username and password for this. After someone logs in to the site this way, they are presented with their individual username and password prompt as part of the web page. The purpose of the initial username/password is to discourage non-technical employees that aren't supposed to be using the page from even viewing it. So far, when we've had to change this password, I've manually gone to each computer and updated the saved password. I'm writing a startup script to configure other aspects of these systems so that I can maintain them easier. I'd like to be able to update the saved password via this script. The operating system running on these machines is Windows XP SP3 and the browsers they're using to access this site are IE8 and IE9. How can I update the saved basic authentication information for a website via a script?

• Command-line access for Apple Time Machine?

  - by Stefan Lasiewski

  We use Apple's Time Machine to back up our workstations at the office. If I want to restore a file, I need to open up the Time Machine GUI and browse files there. The GUI is ugly eye-candy and gets in my way. Is there a way to browse the Time Machine archive using the Mac's command-line? I'm used to Netapps and other storage appliances. I use backintime for my Ubuntu workstation. To restore a file with one of those systems, you can restore a file with a simple command like: cp .snapshot/daily.0/filename.txt . or cp /backup/backintime/20100611-000002/backup/etc/shadow /etc/shadow Is there an equivalent for Apple's Time Machine?

• Distributed Nagios Installation

  - by kruczkowski

  I'm looking for a plug-in or product that will act as a remote probe and perform tests then send back the results to the central Nagios server. Reason for this is that I'd like to monitor internal systems and servers at customers, but don't want to allow all the traffic passing the firewalls. Ideally I'd like a soft-probe that would be installed and then perform the tests and send back the results (via SSH) to the central Nagios installation. Does anyone know of a product or plug-in that would offer such service? If not Nagios, is there any other monitoring system that does such a thing (ideally open-source)?

• I have a server running Windows 2008 R2 Core and it needs to hosts either SVN or GIT

  - by Jason Adams

  The server allocated for our cross platform projects (both Mac & PC) source repository is running Win2008R2 Core. We're really happy with its stability and we aren't interested in moving over to non-core. We need to get either SVN or GIT installed on the aforementioned box in the shortest amount of steps. We know the advantages/disadvantages of both systems. That being said, we don't care which one we use, we're just are looking for the path of least resistance on setting up a repository on a machine running R2 core.

• ntbackup workalike for adhoc full backups in Windows 7 thats free and preferably open source

  - by Justin Dearing

  On windows 2000 and XP machines I used to be able to do the following: ntbackup backup systemstate c: /f e:\backups\machineName\machineName-full+systemstate_200101206.bkf This gave me a full backup of the system that I could use to do a system restore, after doing a barebones OS install. Windows 7 has a great utility for regular backups with alerting and all that stuff. It does not seem to have command line support. I'd like a backup solution for my Windwos 7 systems that has the following features: Is free Is open source (preferebly) Works while the system is booted and leaves the system functional (clonezilla is great for offline backups, and I use that too) Gives me a backup that is suited for a full system restore or partial system restore (ruling out most imaging software even if they could work while the system is booted via some sort of shadow copy voodoo) Can work via the command line Compression would be nice, the ability to pipe output would be better.

• Disable NSS LDAP IPv6 (AAAA) lookups

  - by pilcrow

  Question: How can I disable inet6 AAAA queries for my LDAP server during (LDAP-backed) NSS lookups on a CentOS (RHEL) 5 machine? Background: I've servers configured to consult ldap://ldap.internal for NSS passwd and group lookups. Every relevant NSS lookup, for example the getpwuid(3) implied by an ls -l which needs to translate UIDs to network user names, performs the following DNS dance before connecting to the ldap server: AAAA? ldap.internal -> (no records) AAAA? ldap.internal.internal -> NXDomain A? ldap.internal -> 192.168.3.89 I'd like to skip the first two queries completely. Configuration: [server]$ cat /etc/redhat-release CentOS release 5.4 (Final) [server]$ grep ^passwd /etc/nsswitch.conf passwd: files ldap [server]$ grep ^uri /etc/ldap.conf uri ldap://ldap.internal/ For what it's worth, IPv6 support is otherwise disabled on these systems: [server]$ grep off /etc/modprobe.conf alias ipv6 off alias net-pf-10 off [server]$ echo "$(ip a | grep -c inet6) IPv6-enabled interfaces" 0 IPv6-enabled interfaces

• In Windows XP, is it possible to disable user credential caching for particular users

  - by kdt

  I understand that when windows caches user credentials, these can sometimes be used by malicious parties to access other machines once a machine containing cached credentials is compromised, a method known as "pass the hash"[1]. For this reason I would like to get control over what's cached to reduce the risk of cached credentials being used maliciously. It is possible to prevent all caching by zeroing HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\CachedLogonsCount, but this is too indiscriminate: laptops users need to be able to login when away from the network. What I would like to do is prevent the caching of credentials of certain users, such as administrators -- is there any way to do that in Windows XP? http://www.lbl.gov/cyber/systems/pass-the-hash.html

• Connecting to a computer using Remote Desktop does not work first time

  - by dev

  Hi all, I'm having a weird sort of problem with Remote desktop and that too, only on one machine. If I boot up this machine, and then try to Remote desktop into it, it does not work.( I get the following error: The client could not connect to the remote computer. Remote connections might not be enabled or the computer might be too busy to accept new connections. It is also possible that network problems are preventing your connection. Please try connecting again later. If the problem continues to occur, contact your administrator. ) But if I physically log into it & then log out, and then try to Remote desktop into it, it works flawlessly. The problematic machine is Xp 64 Bit, but other systems with Xp 64 Bit work fine. Any Ideas on how to solve this?

• How do I create a free server-side database to be accessed via Windows forms and/or browser?

  - by NoCatharsis

  I have no formal education in databasing or programming, but I've learned enough SQL, C++, and C# to at least get started setting up a small database on my company's server. Using MS SQL Server 2008 R2, I have created the database and set up columns with proper data types. However, there seems to be a lot of tweaks and details that are way over my head. Since I would like these data to be accessible to the other 7 or 8 people in my office (preferably via web browser), I'm wondering whether this is the best setup for my situation. The other option I've read about is a LAMPP server, which I assume is the competing free option to Microsoft's Express packages. I know nothing of LAMP servers except from the articles I've read on how to set them up (and I believe I even saw a detailed tutorial somewhere). To summarize, my question is this: Which of these (or any other) server setups would best suit my purposes, keeping in mind that I'm a true novice (but willing to learn), and would like to keep it free until I get more experience?

• Shared storage for web cluster

  - by user52475

  Hi all! Have a big question about shared/clustered/distributed file system for storage. It will shared storage for shared web hosting (web files + maildir) and OpenVZ containers storage . Have any one working example of such system? The options are: Lustre GFS1/GFS2 - GFS2 - as I understand is EXPERIMENTAL... NFS This 3 systems which I consider for shared storage. Now I have storage with HW RAID 10 - 1TB. NFS - As I know there will be problem with locking? GFS/Lustre - problems when there will be a lot of small files , what is typical for hosting environment and problems with maildir.

• Do I need to run a verfication on LTO tape backups even though the drives themselves perform verification as they write?

  - by ObligatoryMoniker

  We have an LTO-3 Tape drive in a Dell media library that we use for our tape backups. The article about LTO on Wikipedia states that: LTO uses an automatic verify-after-write technology to immediately check the data as it is being written, but some backup systems explicitly perform a completely separate tape reading operation to verify the tape was written correctly. This separate verify operation doubles the number of end-to-end passes for each scheduled backup, and reduces the tape life by half. What I would like to know is, do I need my backup software (Backup Exec in this case) to perform a verify on these tapes or is the verify-after-write technology inherent in LTO drives sufficient? I would also be curious if Backup Exec understands the verify-after-write technology enough to alert me if that technology couldn't veryify the data or will it just ignore it making it useless anyway since even if the drive detecs a problem I would never know about it.

• Environment variable for volume names in Windows?

  - by Shinrai

  I'm trying to write a batch file that will look at the volume label of the current drive and report if it's not equivalent to a certain string. Is there a default variable in the shell for this? Can I define one? Am I SOL and I'll actually have to do some (shudder) programming? EDIT: If this is possible in PowerShell that would work fine. (For the curious, we ship our machines with software cloning as a rapid bootable backup solution since most of our customers are daytraders and aren't interested in RAID due to urgency of getting-the-hell-back-to-work-right-away if there's a software corruption problem, and we want to make it immediately obvious if they're booting to the backup drive unintentionally, like say the primary failed entirely. The hope was just to write a simple batch file that would autostart on boot and throw a warning in the event of a problem.)
