• Is the native DHCP client for MacOS X able to send "Vendor class identifier" (opTag 60) in a DHCP request?

  - by plluksie

  Is it possible for MacOS X (current version or in any previous one) to easily force DHCP client to send to DHCP server, at the beggining of the conversation - in DHCPDISCOVER packet - option "Vendor Class Identifier" (60) set to some value? I know that I can install i.e. ISC DHCP client through pkgsrc which supports VCI, but I'm looking for something native. Thank you in advance for information.

• Fixing BIND9 rndc error "connection to remote host closed"

  - by Josh

  I just made some changes to a DNS zone in Webmin and clicked the "Apply Changes" button. I received the error message: rndc: connection to remote host closed This may indicate that the remote server is using an older version of the command protocol, this host is not authorized to connect, or the key is invalid How can I troubleshoot / repair this? I copied parts of the BIND config from a failing server, so I suspect that's what causing it...

• Linux - Scriptable email client?

  - by Phog

  Hi, I'm writing a simple UI for the visually impaired using a speech synthesizer. I've looked all over the internet for an email client which I can script to fit these purposes but to no avail. I believe several CLI email clients(eg MUTT) allow sending emails with command line arguments only. But I've yet to find a client that can download the emails, decode them and then dump them to a text file. The best candidate so far seems to be mailx, but it seems like it needs quite a lot of babysitting to fit my needs. Any suggestions for scripting-friendly email clients? Am I missing something fundamental about MUTT? Are there any libraries/programs that help me decode the MIME encoding used in todays emails from a maildir? Should I just bite the bullet and write a script for mailx? Thanks in advance.

• Manipulating IIS7 Configuration with Powershell

  - by John Price

  I'm trying to script some IIS7 setup tasks in PowerShell using the WebAdministration module. I'm good with setting simple properties, but am having some trouble when it comes to dealing with collections of elements in the config files. As an immediate, example, I want to have application pools recycle on a given schedule, and the schedule is a collection of times. When I set this up via the IIS management console, the relevant config section looks like this: <add name="CVSupportAppPool"> <recycling> <periodicRestart memory="1024" time="00:00:00"> <schedule> <clear /> <add value="03:31:00" /> </schedule> </periodicRestart> </recycling> </add> In my script I would like to be able to accomplish the same thing, and I have the following two lines: #clear any pre-existing schedule Clear-WebConfiguration "/system.applicationHost/applicationPools/add[@name='$($appPool.Name)']/recycling/periodicRestart/schedule" #add the new schedule Add-WebConfiguration "/system.applicationHost/applicationPools/add[@name='$($appPool.Name)']/recycling/periodicRestart/schedule" -value (New-TimeSpan -h 3 -m 31) That does almost the same thing, but the resulting XML lacks the <clear/> element that is created with via the GUI, which I believe is necessary to avoid inheriting any default values. This sort of collection (with "add", "remove", and "clear" elements) seems to be fairly standard in the config files, but I can't seem to find any good documentation on how to interact with them consistently.

• php not working with apache install

  - by fivelitresofsoda

  hi, I have a centos server. I have installed apache 2.2.17 from a .tar.gz file. I've also install php 5.3 from the ius repository. That worked fine and apache is functioning and so is php 5.3. However, when i put a phpinfo.php file in the directory that apache should be serving files from, it doesn't work. I can only seem to get php to work if i use yum install httpd which installs an older vesion of apache. Any ideas? Thanks.

• Apache rewrite - optional parameters?

  - by Mayhem

  I'm creating SEO friendly urls for my news page. My links look like this : www.site.com/1234/the-pretty-url-string/ RewriteRule ^([^/])/([^/])/$ /news.php?sid=$1&url=$2 [L] This works great, but I like to have more flexability. I want to be able to accept urls like : www.site.com/1234 www.site.com/1234/ so then I can do some php $GET's and figure out if anything is missing - and 301 to the proper URL of my choice. I would like the &url=$2 to be optional.

• Something is spamming from my hMail server - how can I deal with this?

  - by joshcomley

  My Windows 2008 server is attempting to send out a lot of spam, I've just discovered, and I'm not sure how to see where the compromise is. For example: has someone hacked an account? Has someone hacked the server? Is there a virus on the server? What can I do to investigate this? Edit Thanks for the replies so far. I am running hMail server, and have spent so long investigating the correct configuration but still I end up with these emails being sent. Here is a screenshot of my Internet IP range settings on the server: (let me know what else I can provide to help)

• Windows Server 2003: Nat Port Forwarding Not Working

  - by jM2.me

  The setup is following: Internet (108.99.XXX.XX) <- Windows Server 2003 (10.0.0.1) <- Switch <- Office Computers (10.0.0.100-200 some static routes some manual some automatic) Windows Server has NAT installed on it and two network interfaces are configured properly. The problem is, whenever I try to forward port 80 (or any other) from office computer (lets say 10.0.0.100), it fails. Nic #1 Settings: All settings are obtained from ISP Nic #2 Settings: Set manually IP: 10.0.0.1 Mask: 255.255.255.0 Nat Server is configured to automatically assign IP addresses to private network. Settings are: IP: 10.0.0.0 Mask: 255.255.255.0 Forwarding was done in Routing and Remote Access (local) - IP Routing - NAT/Basic Firewall - Local Area Connection (right click_properties) - services and ports - Web Server HTTP - Private Address: 10.0.0.100 SO what is causing the problem of failure to forward any port from other computer inside private network?

• Mac OSX Server - Mac Mini to XServe Migration

  - by notpeter

  If I build out a Mac OSX Server install on a Mac Mini and then when it's ready for production I image the disks to an XServe, is there any reason the resulting system won't just work? Assuming I'm able to keep the same IP address are there any other issues I should be aware of? I'll be running minimal services, just AFP, SMB and Open Directory. TMI: My Intel XServe is full of cruft. Was originally a G4 XServe running 10.3, upgraded to 10.4 then migrated to 10.5 on the Intel XServe. I'd like a clean start, but can't spare the XServe downtime while I build out the install, can I just use a Mac Mini for dev and then switch to the XServe for production.

• Where to set permissions to all server for logon trigger on sql server 2005

  - by Jay

  I need to keep track of the last login time for each user in our SQL Server 2005 database. I created a trigger like this: CREATE TRIGGER LogonTimeStamp ON ALL SERVER FOR LOGON AS BEGIN IF EXISTS (SELECT * FROM miscdb..user_last_login WHERE user_id = SYSTEM_USER) UPDATE miscdb..user_last_login SET last_login = GETDATE() WHERE user_id = SYSTEM_USER ELSE INSERT INTO miscdb..user_last_login (user_id,last_login) VALUES (SYSTEM_USER,GETDATE()) END; go This trigger works for servers that are system admins but it won't allow regular users to login. I have granted public select,insert and update to the table but that doesn't seem to be the issue. Is there a way to set permissions on the trigger? Is there something else I am missing? Thanks

  Hi, I have to install php5.3 on my centos server. If i do yum install php, the base repo installs 5.1.6 which is too old for the apps i need to install.

• Using e-mail address as user name for SMTP and POP3

  - by PeterMmm

  I have a exim4 setup as SMTP. My user naming schema is to name all mail users for this server as m001, m002, m003, ... and then redirect to a real e-mail address with virtual domains. How can I allow my users to authenticate with exim to send mail using either their system user name (m001) or the email address ([email protected])? User login information for m001 are stored in linux system files (passwd, shadow). They are linked thru entries in a virtual address table for each domain that this server can serve: # /etc/exim4/virtual/example.com m001: [email protected] m002: [email protected] m003: [email protected] The same can be applied to qpopper ?

• Java plugin doesn't work in Chrome -- how can I fix this?

  - by Chris Farmer

  This used to work fine until a week or so ago, and I am not sure what has changed since then. I have just uninstalled what seems to be all the JVM stuff on my machine and reinstalled with the latest recommended Java version from java.com (1.6, update 23). The plugin works fine in IE and Firefox, but in Chrome it fails and the pages that try to use the plugin act as if Java is not installed. I have tried this in both Chrome 8 and Chrome 9 with the same result. How can I diagnose and fix this?

• Toshiba satellite u400 hardware buttons, which software?

  - by Kugel

  I've recently intalled Windows 7 64bit onto my Toshiba U400 laptop. I went over to toshiba support-download-drivers page and downloaded every driver that was missing. I chose not to download bloated stuff, only the drivers. Win7 has much better control over hardware buttons out of the box then I had before. But there is one thing that annoys me. I have hardware button on the laptom that is supposed to switch LEDs on/off. Windows 7 turns my sound on/off instead. The second minor thing is, when I turn off sound by pressing Fn+Esc (or light off button;-), the sound is off, however any slight touch with volume wheel turns it right back on! This is something that Ubuntu does also out of the box. I wonder what's the logic behind this. Any lightweight solutions to these out there? Thank you

• Proper way to configure ~/.Xsession with a standalone window manager to gracefully end a session

  - by cYrus

  I'm using xdm and my ~/.Xsession looks like this: # <initialization stuff here> exec openbox It works, but I've noticed that when I log out Openbox doesn't gracefully kill all the applications. In particular Google Chrome complains about that. How can I make sure to wait for all processes to exit (just like others configurations: Gnome, KDE, Windows ...)? The only (ugly) solution that I've found involves sleep and kill into ~/.Xsession.

• Sleep uses more power than I expect

  - by Niklas

  When my new Dell laptop with Windows 7 Home Premium and 4GB RAM sleeps (not when it hibernates), it will drain the battery overnight. My old Dell laptop with XP Pro (2 GB RAM) could sleep for days without running out of battery. Is it normal that Windows 7 sleep is this power-hungry or should I troubleshoot my new machine? Edit: I know how to set the different sleep/hibernate settings. That is not what I'm asking.

• Windows Photo Viewer can't open this picture because you don't have the correct permissions to access the file location

  - by Software Monkey

  My system in Windows 7 and fully up to date with all patches and options (except for Microsoft Silverlight, which I refuse to install). I get this error whenever I try to open an image using Windows Photo Viewer, such as when previewing from Explorer or when opening an image attachment to an email. I have already verified correct permissions to the file and all folders in the path. The strange thing is that every other program I have seems to open the images fine, including "Slideshow" from Windows Explorer. Even more strange, in WPV there is an "Open" menu that lists the other programs for images including GIMP and MS Paint and they open the very file that WPV is complaining about just fine. That should eliminate permissions as being the problem, especially since (logically at least) they are read/write while WPV is read-only. I have even edited and saved the images that WPV does not open. I am out of ideas, and searching for answer on the Web has resulted only in the same tired repitition of some flavor of "take ownership and reset permissions for the entire drive", which I have already done. And which is counter-indicated by the fact that only Windows Photo Viewer seems to have a problem. The one thing which is slightly unusual is that for normal files they are all on a second HDD mounted into C:, however for email attachments the temporary folder is C:\Temp\, which is directly on that drive.

• Photoshop changes tablet screen area

  - by Zonda333

  Usually my Wacom Bamboo tablets screen area (Area which cursor can go using tablet) is as set - One (1280x1024) monitor. However, when I run any Adobe Product, such as PhotoShop or Illustrator (CS5 or CS4), and it is the active window, my screen area reduces to around 400x400, effectively making itself absolutely useless. If another program is the active window, it works fine. Running Windows 7 32-bit, with up-to-date tablet drivers. Does anyone know a fix for this?

• Resize windows command line prompt?

  - by Yuval

  Hi, I'm working on a Windows xp machine. I wrote a program in assembly that outputs some text, and am trying to create a screenshot of the command line output (start-run-"cmd"). The problem is that the text initially printed by the program gets pushed up by later text and I cannot scroll to it. I tried playing around with the width and height under properties = layout but it seems to resize the window itself (the borders) without resizing the textarea inside the window (text does not have more "room", but the window is bigger). Does anybody know a workaround/solution for this? Thank you!

• Forwarding audio like X in SSH

  - by Akilan

  While it is possible to use X applications remotely by using -X switch in ssh, the sound is being played in remote machine's speaker only. For example if I view a film in VLC/Totem only video is visible and I can't hear the audio. Is there a way to forward audio too? [without digging through Pulse-audio's setup, I mean; Like how ssh understands X forwarding by itself.] I have tried this only in Ubuntu (in various Ubuntu versions from 9.10 through 10.10), if that helps.
