• Test Environment configuration Management

  - by TechTestDude

  I am after a solution which will enable me to enter all my hardware/software elements (sort of like resource management), create a set of 'test environments' and assign hardware and software to that test environment for a given period. The idea is so that everyone can see and update what they need in any given environment to meet their project needs. Does anyone know of any systems out there which can achieve this? Vendor recommendations are welcome, but please call out your interest in it.

• Stop SQL Server services from conveniently

  - by MedicineMan

  I have a general use laptop. I use it for games, development, and web surfing. I've just installed SQL Server 2008 with Analysis, Reporting, and Error reporting, as well as any of the other options on the installer. I also have a default instance of SQL server as well as a named instance. When I'm not doing development, I'd like to shut down these services conveniently. I'm thinking that a batch file would be good. What are the commands to shut these services down and release the associated memory and resources? It appears that: net stop MSSQLSERVER seems to stop the MSSQLSERVER instance. What about the other services?

• solr administration

  - by devrick0

  Does anyone have any notes for an sysadmin supporting solr? I'm looking for anything that might be useful for monitoring & metrics as well as troubleshooting. Some useful links I have found are: /solr/admin/stats.jsp and /solr/admin/analysis.jsp In the logs I have noticed, other than the query, "hits", "status" and "QTime" values. The documentation on what these mean is sparse at least based on the 100+ websites I have checked. QTime appears to be the query time response in milliseconds. Hits is some form of results but I'm not sure exactly what makes that up and I'm not sure about status. Typically I see status come back as "0" but I have seen other numbers such as "5", so my thoughts that it could be either HTTP status codes or a 0 or 1 (good or bad) methodology isn't accurate. All of the documentation I have come across is intended for developers. Any sysadmin-centric documentation would be a big help.

• Why is setuid ignored on directories?

  - by Blacklight Shining

  On Linux systems, you can successfully chmod u+s $some_directory, but instead of forcing the ownership of new subdirectories and files to be the owner of the containing directory (and setting subdirectories u+s as well) as you might expect, the system just ignores the setuid bit. Subdirectories and files continue to inherit the UIDs of their creating processes, and subdirectories are not setuid by default. Why is setuid ignored on directories, and how can I get the system to recognize it?

• Is VirtualBox really slow compared to the host OS? (for Ruby development)

  - by dan

  I have VirtualBox running Ubuntu as a guest environment on my Macbook Pro running Leopard OS X 10.5. I timed the same batch of Ruby on Rails unit tests on both systems. The difference seems to be quite big. The same suite of Ruby unit tests that take 13.4 seconds in the native OS X, take 82 seconds to run in VirtualBox Ubuntu. Are other people doing the same kind of development noticing the same differences?

• Finding trends in multi-category data in Excel

  - by Miral

  I have an Excel spreadsheet that contains hundreds of rows of data that each represent a single sample in a larger population. Each row is divided into three columns that contain frequency counts of a specific type of thing. Together the three columns summed on a single row represent 100%, though each row will sum to a different value. What I'm most interested in are the proportions of each of these types (ie. percentages of each column relative to the sum of the three columns). I can easily calculate this on a per-row basis, but what I'm really interested in is trying to find an overall trend from the entire population. I don't really spend much time doing data analysis so the only thing I can think of trying is to create those percentage columns and then average them, but I'm sure there must be a better way to visualise this.

• Identical traffic

  - by Walter White

  Hi all, I am running an application server and logging all requests for analysis purposes later. One interesting trend I noticed last night was, I had a visitor from Texas on FIOS share identical traffic with bluecoat in California. What would cause the traffic to be identical? For every request the visitor made, bluecoat made one subsequently within milliseconds of his request. If it is caching, why would there be identical requests? Wouldn't it go through the cache / proxy on their end, and I would only see the proxied request? I'm just curious, this is an interesting pattern that shows similarities of a DDoS attack, but with far fewer resources. Is it possible that the visitor had malware on their computer? Any other ideas? Walter

• What character to separate words in filenames? Dashes? Periods? Underscores?

  - by Christopher Albon

  This question isn't about a specific programming language, but more about general best practices. What characters are best (greatest compatibility over programming languages, OSs, file systems, etc.) to separate words in filenames? For example: file.name.txt file_name.txt file-name.txt FileName.txt filename.txt

• Awstats messaging non existant user causing exim4 to go nuts

  - by Chris

  I've taken over managing a server set up by someone else now uncontactable, while managing to work out most faults / changes needed this one is stumping me. Awstats is running on the machine and sending messages via exim4 to a user every time it runs an update. The user account has been deleted and so the exim4 main log files are filling up with message delivery errors, which firstly hinders meaningful log analysis for anything else and secondly uses up quite a lot of space (it grew to 22GB unattended, panic!) I've been through all the conf files in /etc/awstats and can't seem to find any mention of this user account. Google just turns up results about how to use awstats to parse exim4 log files. So the questions is where is this setting (on debian) likely to be? Cheers in advance

• Reg Query Issues

  - by Fitz

  I have a batch script that does reporting on our systems and part of it queries the registry for information. The script fails to get the key's value when its ran by the system, but whenever I run the script myself, it works perfectly the command: REG QUERY "HKEY_LOCAL_MACHINE\SOFTWARE\TrendMicro\ScanMail for Exchange\CurrentVersion" /v PatternStringFormatted > current1.tmp should return: HKEY_LOCAL_MACHINE\SOFTWARE\TrendMicro\ScanMail for Exchange\CurrentVersion PatternStringFormatted REG_SZ 6.645.00 This script is failing on a Server 2008 R2 machine, but runs fine on Server 2003 R2 machines.

• Hide Spotify from Windows 7 Task Bar

  - by Tomas Lycken

  When Spotify is running, it shows a little icon in the activity field. On most operative systems, closing the Spotify window minimizes the player to the activity window, freeing up space in the task bar - but not in Windows 7, it seems. I think it's a little uneccessary to have two icons in almost the same place that does almost the same thing. Is there anyway to hide a program icon from the task bar, in this case specifically Spotify?

• Is there any SMS/MMS server for LAN environment

  - by Chau Chee Yang

  I am looking for a solution to send SMS/MMS message to mobile device from desktop or browser in LAN environment. As such, it is most probably using TCP/IP protocol to transmit request/response. The server may attach to a GSM device with SIM card attached. An server application would then start accept the request from any LAN client and convey the SMS/MMS to one or more recipients. The server may log all requests for further traffic analysis in later stage. Is there any solution that able to perform what I describe here. Please advice.

• Backup Xen domU machines while running.

  - by Jonathan Hawkes

  The host machine is running CentOS 5.3 and using LVM to create Logical Volumes (LVs) and to allow live snapshots to be taken of those LVs. My thought was to store all of the image files for the Xen underpriviledged domains (domU) in a single LV and periodically take a snapshot of that LV and copy the disk images out of the snapshot in order to make a live backup of these systems. Is this doable? Is there a better way? Thanks!

• Cannot connect to a 2008 sql server named instance hosted in a azure virtual machine

  - by emardini

  When I try to connect to a named instance in a SQL SERVER hosted in a azure VM I get this message: A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified) (Microsoft SQL Server, Error: -1) The problem is the sql browser is not working properly, when I start the sql browser service it closes after a few seconds and the event log says "There are no instances of SQL Server or SQL Server Analysis Services." But I do have a named instance, I can connect locally to this instance. I've re-installed sql browser and the instance but ii does not work. The host is a azure virtual machine windows server 2008 datacenter. Please help. Thank you

• Running SEP scans with the SYSTEM account

  - by Eric

  I need to run Symantec Endpoint Protection scans on Windows 7 systems using the SYSTEM account. I know that I can run DoScan.exe to manually run a scan, and this works fine using a regular user account. Unfortunately, when I try to run DoScan as SYSTEM, the application exits immediately without running a scan. Is there a way that I can get this to work, or another application besides DoScan.exe that I should be using?

• What is the S.M.A.R.T. page?

  - by Mads Skjern

  I've just listened to Steve Gibson talk about his SpinRite software, on the Security Now podcast episode 336 (transscript). At 33:20 he says: I can show and do show on the SMART page that sectors are being relocated and that errors are being corrected. That SMART analysis page sometimes scares people because it shows, wait a minute, this thing says we're correcting so many errors per megabyte. What is this SMART page? 1) Some information saved on the HD by SMART, that I can access with a SMART tool like smartmontools? 2) A page (tab) in his SpinRite software? In any case, can I see, in any way, what sectors are marked as bad, without using SpinRite? Preferably using smartmontools!

• Monitor utilities

  - by Adam Davis

  I'm a big fan of good monitor usage, but only currently use a few utilities to help me attain display nirvana across several systems and monitors. Part of this is due to not knowing what's available. Please list one monitor utility that you use and what it does for you per answer, and avoid duplicates - comment on and vote up the existing answers rather than adding a duplicate. Also, if there are existing questions that delve more specifically into one area of monitor utilities link that in a separate answer. -Adam

• Packet logging on PIX firewall

  - by georged.id.auindex.htm

  We have a Cisco PIX 515 firewall and I would like to set up a simple logging that would give us a traffic breakdown for billing by: source destination protocol port size time PIX is plugged into Catalyst 2970 and I was told that the best thing since sliced bread for logging is to get Netflow and get Catalyst to log. My concern, however, (besides the Netflow cost) is that I really don't want to "listen" to the internal noise and all I'm interested in are the external traffic stats above for billing and analysis purposes. What would be the simplest and the easiest solution? Cheers George

• Querying Domain Controller objects using Powershell

  - by Neobyte

  Could someone explain to me why this does not work? Import-Module ActiveDirectory $dcs = Get-ADComputer -Filter {DistinguishedName -Like "*Domain Controllers*"} I get no results for this query. Alternatively, could someone suggest a way using the module above that I can generate a list of systems on my domain that are NOT Domain Controllers (which is what I'm eventually trying to achieve). Cheers
