• Restrict SMB user from changing password

  - by Canadian Luke

  On a server running Debian Wheezy and Samba ver 3 with a tdb backend, how do I restrict a single user from changing the password? This account is one of 2 generic accounts, one for students and one for Teachers on Call (TOC). The users are created, but I'm not deploying the server yet. When looking through Google, I came across setting the maximum password age, but not setting the minumum password age (I'd be happy with a 5 year password...)

• asterisk queues priority and penalty

  - by MealstroM

  queues.conf shared_lascall=yes strategy=rrmemory wrapuptime=15 A1,A2,A3 are members of 2 queues: queue1(Q1) and queue2(Q2) A3 has penalty 3 in Q1 where min/max penalty are 0/3 and A3 has penalty 0 at Q2 where min/max penalty are 0/3. A3 has just ended a call and is on wrapuptime pause. User1 (U1) enters Q1 with priority 10, and user2 (U2) enters Q2 with priority 15. A3 wrapuptime ends. What user U1 or U2 will be served first?

• Can a password change in Active Directory be reverted?

  - by Jordan Milne

  I often need to log in with a user's domain account to make sure that I've set up their profile correctly, but there's no easy way to do this other than to call them and give them a temp pass and force them to change it (bad, since they often forget it,) or ask for their password (worse.) Is there any way to change a user's password, then set it back to the original later? I tried to see if there was any way to get the NTLM hash so I could set it back later, but there doesn't seem to be a facility for that built into AD.

• Windows 7 losing one of my displays after restart

  - by j_kubik

  I have an Intel DZ68BC motherboard with Intel HD graphics card using two monitors (on DVI and on HDMI » VGA). My friend asked me to test if his NVIDIA graphics card works well on my computer (at his it was doing some trouble), so I inserted it in my computer, installed the NVIDIA driver and it worked quite well. Then I removed it, uninstalled everything NVIDIA-related I could find and switched monitors back to my Intel card. Since then after every system start/restart, the system sees only monitor on HDMI » VGA connector, completely ignoring the DVI monitor. I noticed that installing the Intel video drivers causes the system to recognize the second monitor if I don't immediately reboot. After a reboot, the system recognizes only the HDMI » VGA monitor. I also tried starting in safe-mode and using DriveSweeper to remove the remains of NVIDIA drivers. While it seems that some drivers were removed, the situation didn't change. Now I am out of ideas and I really wouldn't like to reinstall the system (again...). I also tried restoring the system to the state before this whole story, but it also didn't change anything. EDIT: I am still trying to troubleshoot this problem. The only point that I could start was driver re-instalation. I traced down the part that restores right settings to a call: C:\Users\Jarek\Desktop\GFX_Win7_64_8.15.10.2696\x64\Drv64.exe -driverinf "C:\Users\Jarek\Desktop\GFX_Win7_64_8.15.10.2696\Graphics\igdlh64.inf" -flags 20 -keypath "Software\Intel\Difx64" This call fixes my displays, and as workaround, I will add it for now to my autorun. I am still looking for better solution anyway... EDIT2: Using DriverView i made a list of currently used drivers both before and after fixing my display using above command. Then i compared logs: No drivers were removed by fixing command. Drivers added by fixing command: MS Remote Access serial network driver (asyncmac.sys) security processor (spsys.sys) Drivers that changed base address (indicates driver-reload?) Canonical Display Driver (cdd.dll) Intel Graphics Kernel Mode Driver (igdkmd64.sys) Monitor Driver (monitor.sys) Added drivers seem rather unrelated to the problem to me, reloaded drivers are just a cnsequence of installing new driver file so there is not much to go here... I really cannot make heads or tails out of it...

• Use /etc/aliases to send to a mailing-list using sendmail

  - by Pixoo

  I'm trying to configure my Debian (6.0) server to forward emails sent to root to a mailing-list. I set the ML address in /etc/aliases this way: root: [email protected] I then called newaliases. It doesn't work but when I call mail from the command line it works :/ echo "test" | mail -s"test message" [email protected] If I set my own email address in /etc/aliases it's working too. Any idea where it could come from ? Thanks

  - by Rev

  Hi I want in call duration between operator and caller,play sound for operator(something like hold music). But in order to play this sound, operator must dial unique code and then sound will be play for caller, and caller only hear that sound file! After that (sound fully played), caller back to operator's queue or something like this. So is this possible to do or not? (if possible, post dial-plan for this too)

• Make website reachable through domain?

  - by Msmit1993

  I'm learning to use IIS 7 but I don't understand how I can make my website available through a domain. I have a domain as example I will call it www.test.com I have made a website in IIS, running on port 80 and can be viewed by typing the IP of the server in the address bar of my browser. So if I type www.test.com in the address bar how do I make my IIS website show up, without a redirect of course, I don't want users to see the IP in the address bar.

• Windows 7: The audio service is not running?

  - by oscilatingcretin

  Why isn't my audio service running? It's so random. Sometimes I am able to change my PC volumn, other times I am not. I've restarted the following services: Remote Procedure Call (RPC) Multimedia Class Scheduler Windows Audio Endpoint Builder I think I started noticing this after I went mucking around in msconfig looking for ways to improve PC performance. I know I shut off some services, but that was over 6 months ago today and I am finally getting tired of it happening.

• What are your tricks for optimizing your Subversion configuration?

  - by Scott Markwell

  For a Linux or Windows system, what tricks do you do to optimize your Subversion server? The following are my current tricks for a Linux system serving over Apache with HTTPS and backed by Active Directory using LDAP authentication. Enabling KeepAlive on Apache Disable SVNPathAuthz Increase LDAP Cache Using the FSFS storage method instead of BDB Feel free to call this into question. I don't have hard proof that FSFS out performs BDB, only lots of tribal knowledge and hearsay.

• Excel 2010: dynamic update of drop down list based upon datasource validation worksheet changes

  - by hornetbzz

  I have one worksheet for setting up the data sources of multiple data validation lists. in other words, I'm using this worksheet to provide drop down lists to multiple other worksheets. I need to dynamically update all worksheets upon any of a single or several changes on the data source worksheet. I may understand this should come with event macro over the entire workbook. My question is how to achieve this keeping the "OFFSET" formula across the whole workbook ? Thx To support my question, I put the piece of code that I'm trying to get it working : Provided the following informations : I'm using such a formula for a pseudo dynamic update of the drop down lists, for example : =OFFSET(MyDataSourceSheet!$O$2;0;0;COUNTA(MyDataSourceSheet!O:O)-1) I looked into the pearson book event chapter but I'm too noob for this. I understand this macro and implemented it successfully as a test with the drop down list on the same worksheet as the data source. My point is that I don't know how to deploy this over a complete workbook. Macro related to the datasource worksheet : Option Explicit Private Sub Worksheet_Change(ByVal Target As Range) ' Macro to update all worksheets with drop down list referenced upon ' this data source worksheet, base on ref names Dim cell As Range Dim isect As Range Dim vOldValue As Variant, vNewValue As Variant Dim dvLists(1 To 6) As String 'data validation area Dim OneValidationListName As Variant dvLists(1) = "mylist1" dvLists(2) = "mylist2" dvLists(3) = "mylist3" dvLists(4) = "mylist4" dvLists(5) = "mylist5" dvLists(6) = "mylist6" On Error GoTo errorHandler For Each OneValidationListName In dvLists 'Set isect = Application.Intersect(Target, ThisWorkbook.Names("STEP").RefersToRange) Set isect = Application.Intersect(Target, ThisWorkbook.Names(OneValidationListName).RefersToRange) ' If a change occured in the source data sheet If Not isect Is Nothing Then ' Prevent infinite loops Application.EnableEvents = False ' Get previous value of this cell With Target vNewValue = .Value Application.Undo vOldValue = .Value .Value = vNewValue End With ' LOCAL dropdown lists : For every cell with validation For Each cell In Me.UsedRange.SpecialCells(xlCellTypeAllValidation) With cell ' If it has list validation AND the validation formula matches AND the value is the old value If .Validation.Type = 3 And .Validation.Formula1 = "=" & OneValidationListName And .Value = vOldValue Then ' Debug ' MsgBox "Address: " & Target.Address ' Change the cell value cell.Value = vNewValue End If End With Next cell ' Call to other worksheets update macros Call Sheets(5).UpdateDropDownList(vOldValue, vNewValue) ' GoTo NowGetOut Application.EnableEvents = True End If Next OneValidationListName NowGetOut: Application.EnableEvents = True Exit Sub errorHandler: MsgBox "Err " & Err.Number & " : " & Err.Description Resume NowGetOut End Sub Macro UpdateDropDownList related to the destination worksheet : Sub UpdateDropDownList(Optional vOldValue As Variant, Optional vNewValue As Variant) ' Debug MsgBox "Received info for update : " & vNewValue ' For every cell with validation For Each cell In Me.UsedRange.SpecialCells(xlCellTypeAllValidation) With cell ' If it has list validation AND the validation formula matches AND the value is the old value ' If .Validation.Type = 3 And .Value = vOldValue Then If .Validation.Type = 3 And .Value = vOldValue Then ' Change the cell value cell.Value = vNewValue End If End With Next cell End Sub

• Can anyone recommend a good BSS/OSS platform for a voip provider?

  - by john unkas

  We are a voip startup and want to launch a voip service, while we have the call control platform (broadworks) we are wondering what BSS/OSS platform to use. Our options are to buy a turnkey solution (if it exists) or else to glue together opensource and commerical offerings to create a complete solution. BSS components we're looking for are identity management, billing, rating, product catalogue, subscription management, reporting, etc..

• What are some potential uses of Asterisk (PBX) for a "power user"

  - by user144182

  So I read a lot of good things about Asterisk. I am not however looking to run a call center or small business setup. I am still interested what potential uses it has for me as a "power user" and what features I could harness for my communication needs. I'll throw out that I currently use other technologies like Google Voice, Skype, and a cellphone of course. So, what potential uses, if any, could Asterisk PBX have for a user like me?

• What is the overhead when redirect through mod_proxy

  - by ivoba

  I have an API that used to run on Apache but now is served via lighttpd. I can easily switch the API URL in the app to the lighty port like api.net:81. I wonder if I should use mod_proxy instead to have cleaner urls. There is no redirect for legacy urls necessary. What would be the overhead for the Apache in between compared to the direct call? Would mod_proxy and Apache steal the benefit of lightys lightweightness?

• Cron - How can I create a cronjob that runs every 15 seconds?

  It seems that Cron doesn't support a seconds interval. What is the easiest way to run a cli script (php) every 15 seconds? Is there a cron tool that works specifically with seconds (then I could use Cron to call it every minute)?

• What is the difference between running a Windows service vs. running through shell?

  - by Zack

  I am trying to troubleshoot an issue on a Windows 2008 server where running attempting to connect to a "Timberline Data Source" ODBC driver crashes if the call is in a "service" context, but succeeds if the call is initiated manually in a Remote Desktop session. I have set the service to run as my user. I'm wondering if, all else being equal (user, machine, etc), are there any fundamental security/environment differences between running a process as a service vs manually? --- Implementation Details --- In case it is helpful for anyone, I had a system that started as an attempt to connect to a Timberline Database using ODBC and a Python CGI script called via IIS 7. The script itself works fine, however, as soon as I attempt to perform the ODBC connect function, the script crashes without throwing an exception. The script was able to connect fine when executed via command line. The same thing happened when using a C#/.net service, attempting to run via Apache, Windows Scheduler or even a 3rd party scheduling tool. With the last option (the 3rd party scheduling tool, pycron) I set the service up log in as my user and had the same issue (I confirmed via Task Manager that the process running user was, in fact, me). It just doesn't make sense to me why a service, which should be running as my user, appears to still be operating in a different security context or environment. Also, if it's important, the Timberline database is referenced by computer name on the network ("\\timberline-server\Timberline Office\Accounts\AT" or something to that effect) I also realized that, as Joel pointed out, the server DOES have a mapped drive ("Y:" which is mapped to "\\timberline-server\Timberline Office") The DSN is set up at the "System DSN" level which, according to the ODBC Administration Tool, means that the DSN is available to users and services Since I'm not allowed to answer this question yet, I'll post the solution that I arrived on: As Joel Coel mentioned, there actually was a mapped drive scenario. I didn't realize this because the DSN specified a path using UNC. However, it seems as though the actual Timberline Driver referred to a mapped drive. Since services don't start with the mapped drive, I was forced to add the drive mapping code into my service. Since it was written in python, I used code from a Stackoverflow answer that was able to map the drive on the fly.

• Creating a Linux cluster/cloud to act as a server.

  - by Kavon Farvardin

  I have about four or five machines in the Pentium 3-4 era and I'm interested in creating a Linux server comprised of these machines. The server's main purposes would be to host several low-medium traffic websites/services (voice and game), and share terabytes of data on a local network. I could probably throw together one modern computer as a server and call it a day, but I'm interested in using these machines to do it instead. Where would I get started in this cluster/cloud setup?

• QNAP (469L) with Debian: can't connect to router

  - by agtoever

  I've been running my QNAP 469L with Debian (Wheezy deb7u3) for a few months. Yesterday I upgraded the memory to 4 GB. The system boots fine, but since the upgrade, I'm not able to connect the server to my router (a TP-Link WR941ND). My configuration: The router runs a DHCP server (192.168.67.100 and up), with a preconfigured ip address for the QNAP (192.168.67.10). The router is on 192.168.67.1. As said, Debian is installed on the QNAP (which can be regarded as a normal computer). Networking hardware on the QNAP: Intel PRO/1000 Network Connection using the e1000e kernel module. This is what I have tried so far: Replace the network cable (tried 3 different cables on different router ports). Check for messages from the kernel: dmesg | grep eth. Besides the normal hardware messages I get a ADDRCONF(NETDEV_UP): eth0: link is not ready for each call to ifup. Manually restart the network sudo server networking restart Check sudo ifconfig (eth0 is up, but no ip addresses). Check the /etc/network/interfaces which has (besides the loopback device) an allow-hotplug eth0 and iface eth0 inet dhcp, which is afaik the default Debian configuration. Since the server has two ethernet ports, I checked if I'm using the right port (checked the hardware address that ifconfig reports for eth0 is the same as the hardware address that is in the preconfigured ip address for the server in the router. Do a manual sudo ifdown eth0 && sudo ifup eth0 with no results (but an extra ADDRCONF(NETDEV_UP): eth0: link is not ready in the kernel log) Do a dhcp request dhclient -v eth0: for about a minute requests are send (according to the terminal) and at the end I get a No DHCPOFFERS received. No working leases in persistent database - sleeping.. Check the router system log if DHCP requests are received. I see them for some devices (my Mac, my iPhone) but not from the QNAP. The log entry looks like: DHCPS:Recv REQUEST from 84:85:06:07:75:6A and then a DHCPS:Send ACK to 192.168.67.101. There are no records from the QNAP's hardware address. So the two error messages that I do get are: ADDRCONF(NETDEV_UP): eth0: link is not ready for every ifup and No DHCPOFFERS received. No working leases in persistent database - sleeping. for every DHCP call.
