• Mailman delivery troubles

  - by stanigator

  I'm not sure if this is a good place to ask this question. It's about mailing list management software called Mailman from GNU. Here are the details: Hosting provider: Vlexofree Domain: www.sysil.com with Google Apps Mailing List created from hosting cpanel: [email protected] I have registered a list of subscribers, and tried sending an email to [email protected]. I got the following error message: Delivery to the following recipient failed permanently: [email protected] Technical details of permanent failure: Google tried to deliver your message, but it was rejected by the recipient domain. We recommend contacting the other email provider for further information about the cause of this error. The error that the other server returned was: 550 550-5.1.1 The email account that you tried to reach does not exist.

• Why is my connection slow?

  - by Jay R.

  I have a Dell Precision T5400 with a Broadcom 1Gb onboard NIC. For some strange reason, when I access machines on our local network, the best I can get is around 125KB/s download speed. My laptop that has a 10/100Mb NIC onboard usually gets around 300KB/s or better from the same network resource. Both machines are plugged into the same 1Gb switch which connects to our local network wall jack at 100Mb half duplex. There is also a printer plugged into the same switch at 100Mb full. The resource I'm using for the test is a 30MB zip file copied from a jetty webserver that is running as part of a cruisecontrol installation. The cruisecontrol installation is running WindowsXP with full real-time antivirus and Altiris patch management and inventory running. That stuff on its own is eating some of the download speed. I've seen the laptop reach into the multiple MB/s download speed before, but the desktop never seems to get past 125KB/s to 130KB/s. In WindowsXP, before I upgraded the driver in the desktop, it was that slow. In Fedora, it is still slow even though it appears to be using the same driver version as the upgraded Windows driver. The upgraded Windows driver is faster, but still not nearly as fast as the laptop. What gives? Any insight to improve the situation would be appreciated. Could it be that the BroadCom board just isn't that good, or the driver in linux is just not as good as the Windows one?

• How to use WPA2 client mode in the Linux-based Cisco WAP4410N access point

  - by joechip

  I have a Cisco WAP4410N access point that I want to use as a client to connect to a WPA2 wireless network (for WLAN service monitoring purposes). Supposedly this access point supports a "Wireless Client/Repeater" mode that allows to do this. The Repeater function is optional (I have that box unchecked so that nobody can connect to this access point wirelessly). I have verified through SSH that the access point gets configured as a client and not as a Master. But it never associates to the SSID I ask it to. This is what iwconfig shows: ath04 IEEE 802.11ng ESSID:"myownssid" Mode:Managed Channel:0 Access Point: Not-Associated Bit Rate:0 kb/s Tx-Power:14 dBm Sensitivity=1/3 Retry:off RTS thr:off Fragment thr:off Encryption key:off Power Management:off Link Quality=0/94 Signal level=161/162 Noise level=161/161 Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:0 Invalid misc:0 Missed beacon:0 Although I've never done this from the command line, I suppose I could use wpa_supplicant or wpa_client to associate it, but I don't know how to do that without editing configuration files and the filesystem is readonly. Besides, I would have to run those commands manually after every reboot. I'd like to know how to do this the Cisco way, if possible. If not, any trick to make this work would be useful. Edit: This is with the latest firmware, 2.0.4.2. And I found that not all of the filesystem is readonly, since /var and /tmp are mounted with type ramfs.

• Overriding vhost.conf to always allow PHP include access to directory

  - by Jeremy Dentel

  My predecessor in my job developed a simplistic newsletter system for our school's newspaper utilizing PEAR's Mail package. As I grow this system (and our site) we are constantly stuck with Plesk rewriting the vhost.conf file in which the PEAR include path has been manually entered. This has become an unwieldy task to actually manage and keep running. There's been a "note" from both the previous developer and I to attempt to solve this problem, but we can't entirely figure it out. I'm attempting a move to cPanel through another host, so hopefully it'll go away there, but until then, it can be tedious extremely difficult to get a solid uptake of the system without constant "web-presence." I've searched around and haven't found a solution. I'm rather new to the server management scene (command line was non-existant till around a year ago. =/), so I haven't found anything. Any help would be useful. "Similar Questions" popped this up, but it still seems to rely on vhost.conf, and will still allow changes within Plesk to overwrite the changes.

• What can cause Powershell execution policy not to be taken into account?

  - by Stephane

  We have in our infrastructure a number of powershell scripts used for various tasks ranging from user login to support technician simulating a user context. These scripts are centralized on our file server (through DFS) for easier management. Some of them are run at logon, some are run through published Citrix applications. We have applied a policy for the whole domain and all users that sets the Powershell execution policy to "unrestricted" so that the scripts can run from the file server. This works perfectly fine for logon script (at least, so far) but for scripts that are run later (usually through a published application but the same applies when using terminal services and a full desktop), the results are inconsistent: some users can run the script fine, some are always prompted in the powershell console for letting the scripts run. I cannot find anything that could cause this behavior and it's really inconsistent: if I start powershell manually and runs get-executionpolicy, I am told that the current policy is unrestricted. Yet, if from the same session I try to run a script through a program that calls powershell <script file name> <parameters> I get prompted before the script can run. What could cause such behavior ?

• How to serve pages through multiple frameworks/template engines efficiently

  - by Leftium

  I would like to render a file that has both PHP tags and Web2Py tags mixed together. To do this, I would like the web server to pass the file through Web2Py, then PHP. I found a method to call PHP from Web2py via Python (based on this method for running PHP on top of django), but this method loses the benefits of any server optimizations from mod_php or FastCGI like caching and multi-threaded operation. A new process is created for each PHP request, which is very slow. Is there a better way to efficiently render pages with both Web2Py(Python) and PHP tags in the same file? Note I am not looking for methods of serving PHP-only and Web2Py-only files from the same server/domain. I prefer solutions for Apache2 or Cherokee. I'm open to using other web servers, though. Background info: I prefer to develop in Web2Py, but we have this pre-existing system written in PHP. I would like to augment the PHP system with some of Web2Py's features like auth authentication/user management and the T() internationalization object. Also it would make it much easier to port the PHP project to Web2Py if it could be done piecemeal. Since the PHP project consists of many files, it would greatly help if they did not need modification.

• How to read cell data in excel and output to command prompt

  - by Max Ollerenshaw

  Hi All, I'm a sys admin and I am trying to learn how to use powershell... I have never done any type of scripting or coding before and I have been teaching myself online by learning from the technet script centre and online forums. What I am trying to accomplish is to open an excel spreadsheet get information from it (usernames and password) and then output it into the command prompt in powershell. When ever I try to do this I get an Exception calling "InvokeMember" anyway, here is the code I have so far: function Invoke([object]$m, [string]$method, $parameters) { $m.PSBase.GetType().InvokeMember( $method, [Reflection.BindingFlags]::InvokeMethod, $null, $m, $parameters,$ciUS ) } $ciUS = [System.Globalization.CultureInfo]'en-US' $objExcel = New-Object -comobject Excel.Application $objExcel.Visible = $False $objExcel.DisplayAlerts = $False $objWorkbook = Invoke $objExcel.Workbooks.Open "C:\PS\User Data.xls" Write-Host "Numer of worksheets: " $objWorkbook.Sheets.Count $objWorksheet = $objWorkbook.Worksheets.Item(1) Write-Host "Worksheet: " $objWorksheet.Name $Forename = $objWorksheet.Cells.Item(2,1).Text $Surname = $objWorksheet.Cells.Item(2,2).Text Write-Host "Forename: " $Forename Write-Host "Surname: " $Surname $objExcel.Quit() If (ps excel) { kill -name excel} I have read many different posts on forums and articles on how to try and get around the en-US problem but I cannot seem to get around it and hope that someone here can help! Here is the Exeption problem I mentioned: Exception calling "InvokeMember" with "6" argument(s): "Method 'System.Management.Automation.PSMethod.C:\PS\User Data.x ls' not found."

• Anonymous access to SMB share hosted on Server 2008 R2 Enterprise

  - by bwerks

  Hi all, First off, I have read through this post and a whole slew of non-SF posts which seem to address the same or a similar problem, however I was still unable to fix my problem. I've got three machines in this situation: a domain-joined server that runs Server 2008 R2 Enterprise ("share server") a domain-joined workstation running XP Pro SP3 ("test server") a domain-unjoined test server running Server 2003 R2 SP2 ("workstation") The share server is exposing a share on the network that the test server must access--it's a Source/Symbol Server share for our debugging purposes. I believe visual studio simply accesses the the share with its own credentials in this case, meaning that the share must be accessible anonymously since the test server isn't joined to the domain and there's no opportunity to supply domain authentication. I've attempted a lot of things to avoid the authentication window when accessing the share: I've enabled the Guest account on the share server and given Guest full sharing/NTFS permissions for the share. I've given ANONYMOUS LOGON full sharing/NTFS permissions for the share. I've added my share to “Network Access: Shares that can be accessed anonymously” in LSP. I've disabled “Network access: Restrict anonymous access to Named Pipes and Shares” in LSP. I've enabled “Network access: Let Everyone permissions apply to anonymous users” in LSP. Added ANONYMOUS LOGON to “Access this computer from the network” in LSP. Added the Guest account to “Access this computer from the network” in LSP. Attempted to provision the share using the Share and Storage Management MMC snap-in. Unfortunately when I attempt to access the share from the test server, I still see the prompt and I'm forced to enter "Guest" manually. I also tried this workflow using the local administrator account on a workstation, and the same thing happens both with and without XP Simple File Sharing enabled. Any idea why I'm getting these results, or what I should have done differently?

• Hyper-V VM Lab + RRAS + RDP

  - by Dennis Evans

  My background is primarily .NET Development with some System Administration skills. I'm trying to set up a VM Lab for me to test System Applications I'm developing but I've only ever done System Administration in already set up environments; I've never set up my own. My current setup: Server 2008 R2 Hyper-V Host on physical machine (only role enabled) with two NICs. First NIC dedicated for Management w/ DHCP address from company's network. Second NIC dedicated to RRAS VM w/ DHCP address from company's network. RRAS VM has two NICS, one is virtual private internal only NIC w/ static entry. The other is the physical NIC mentioned above. I've joined it to my VMLab.net internal domain. My Active Directory Domain Controller server (ADCT) also runs DNS, DHCP, and Certificate Services which I'm familiar with but don't understand completely. RRAS is already set up with NAT to provide the private internal network with Internet access. What I would like to do is be able to RDP into the servers/computers on the VMLab.net domain from my computer. Do I need to add the Remote Desktop Services role and enable the Remote Desktop Gateway service on RRAS in order to do this or is there a way to set up port forwarding on RRAS to just allow a direct connection to the internal servers...or both? What would the best practices be here? Network Diagram http://i.stack.imgur.com/4qfnk.png

• SSD causing 100% CPU usage in Apache/PHP

  - by Tim Reynolds

  I wanted to increase the performance on my development laptop so I added an Intel 320 Series SSD as my primary drive. Everything is amazingly fast, as expected, except Apache/PHP. I develop Magento by using an Ubuntu 10.10 virtual machine. Information: Host OS: Win 7 Professional 64bit Guest OS: Ubuntu 10.10 32bit Processor: i7 Chipset QM55 SSD: Intel 320 Series 160gb 30% full HDD: Hitachi 320gb 50% full (in side bay using an adapter) Laptop: Lenovo T510 Using: Shared folders Apache Version: 2.2.16 PHP Version: 5.3.3-1 APC Version: 3.1.3p1 APC Memory: 128M Using tmpfs for cache, log, session directories in Magento In the VM running on the SSD (VM files and source files are on the same drive) loading a product page in the Admin takes on average 26.2 seconds and uses 100% CPU for nearly the entire time. In the VM running on the old HDD loading the same page takes on average 4.4 seconds. It mostly uses around 40-50% of the CPU while rendering the page. I have read this post: Performance issues when using SSD for a developer notebook (WAMP/LAMP stack)? It says to change some settings in the bios. I have turned any and all power management features off in the bios. I can't for the life of me understand why this would be happening.

• Windows 7 pc freezes for an indeterminate amount of time after unlocking

  - by pikes

  Not sure if this type of question is appropriate for this forum, but I've tried everything I can think of to solve this problem aside from format/reinstall. I recently got a new work PC (Dell optiplex 755) with windows 7 professional x64. Standard developer software installed for .net development: VS2008, VS2005, SQL management studio, office 2007, etc. Recently I've been having this weird problem where after I lock my pc, when I try to unlock it, the screen will be black for awhile after unlocking. I can ctl+alt+del and put my password in but then it just goes black. The amount of time on the black screen seems to be related to the amount of time I am away from my PC. If only away a few minutes, it'll take about a minute to get to the desktop. If away for an hour, could take up to 15 minutes. If I lock it and go home for the night, I have to restart my PC in the morning (I've let it sit for an hour after a night of being locked and nothing happened). It doesn't do it every time but definitely the majority of the time. One weird thing I've seen is that if I remote into my machine before trying to log back in it does not do it. I uninstalled all software back to the point when I remember it started happening and it still does it. I was using this PC for a few weeks without this problem happening at all. Anyone know what my next troubleshooting steps could be? My IT department tried to fix it by moving my old profile to another disk and having me log in, effectively recreating a profile from scratch but that didn't solve it. As I said above if this isn't the right forum for these types of questions please let me know. Thanks in advance!

• Optimizing Disk I/O & RAID on Windows SQL Server 2005

  - by David

  I've been monitoring our SQL server for a while, and have noticed that I/O hits 100% every so often using Task Manager and Perfmon. I have normally been able to correlate this spike with SUSPENDED processes in SQL Server Management when I execute "exec sp_who2". The RAID controller is controlled by LSI MegaRAID Storage Manager. We have the following setup: System Drive (Windows) on RAID 1 with two 280GB drives SQL is on a RAID 10 (2 mirroed drives of 280GB in two different spans) This is a database that is hammered during the day, but is pretty inactive at night. The DB size is currently about 13GB, and is used by approximately 200 (and growing) users a day. I have a couple of ideas I'm toying around with: Checking for Indexes & reindexing some tables Adding an additional RAID 1 (with 2 new, smaller, HDs) and moving the SQL's Log Data File (LDF) onto the new RAID. For #2, my question is this: Would we really be increasing disk performance (IO) by moving data off of the RAID 10 onto a RAID 1? RAID 10 obviously has better performance than RAID 1. Furthermore, SQL must write to the transaction logs before writing to the database. But on the flip side, we'll be reducing both the size of the disks as well as the amount of data written to the RAID 10, which is where all of the "meat" is - thereby increasing that RAID's performance for read requests. Is there any way to find out what our current limiting factor is? (The drives vs. the RAID Controller)? If the limiting factor is the drives, then maybe adding the additional RAID 1 makes sense. But if the limiting factor is the Controller itself, then I think we're approaching this thing wrong. Finally, are we just wasting our time? Should we instead be focusing our efforts towards #1 (reindexing tables, reducing network latency where possible, etc...)?

• Central Authentication For Windows, Linux, Network Devices

  - by mojah

  I'm trying to find a way to centralize user management & authentication for a large collection of Windows & Linux Servers, including network devices (Cisco, HP, Juniper). Options include RADIUS/LDAP/TACACS/... Idea is to keep track with staff changes, and access towards these devices. Preferably a system that is compatible with both Linux, Windows & those network devices. Seems like Windows is the most stubborn of them all, for Linux & Network equipment it's easier to implement a solution (using PAM.D for instance). Should we look for an Active Directory/Domain Controller solution for Windows? Fun sidenote; we also manage client systems, that are often already in a domain. Trust-relationships between Domain Controllers isn't always an option for us (due to client security restrictions). I'd love to hear fresh ideas on how to implement such a centralized authentication "portal" for those systems.

• 553-Message filtered - HELO Name issue?

  - by g18c

  I am having major issues sending from my SBS2011 machine to Message labs server-13.tower-134.messagelabs.com #553-Message filtered. Refer to the Troubleshooting page at 553-http://www.symanteccloud.com/troubleshooting for more 553 information. (#5.7.1) ## I have changed the IP and hostnames from the below. I am not on any IP or domain blacklists. I have setup SPF (which includes mailchimp servers): v=spf1 mx a ip4:95.74.157.22/32 a:remote.mydomain.com include:servers.mcsv.net ~all I am sure i have setup my HELO names correctly under the Exchange Management console, sending a test email from the SBS server and looking at the header shows the following: X-Orig-To: [email protected] X-Originating-Ip: [95.74.157.22] Received: from [95.74.157.22] ([95.74.157.22:52194] helo=remote.mydomain.com) by smtp50.gate.ord1a.rsapps.net (envelope-from <[email protected]>) (ecelerity 2.2.3.49 r(42060/42061)) with ESMTP id 11/90-10010-E529C835; Mon, 02 Jun 2014 11:04:09 -0400 Received: from MYSBSSVR.mydomain.local ([fe80::3159:95a6:23f:1bef]) by MYSBSSVR.mydomain.local ([fe80::3159:95a6:23f:1bef%10]) with mapi id 14.01.0438.000; Mon, 2 Jun 2014 19:03:56 +0400 Is is the main helo name there OK and do i need to worry about the second Received block where the MYSBSVR.mydomain.local is mentioned? I have asked the ISP to set the reverse DNS for my IP to remote.mydomain.com but they have instead put remote.MYDOMAIN.com - would this case cause HELO lookups to classify this as not matching? Anything else I can do to find out why i am being filtered?

• Where is the bare cygwin package list located and how do I manipulate it?

  - by matnagel

  Where is the bare cygwin package list located and how do I manipulate it programmatically or from a shell or with a different method than the gui? I know the gui (setup.exe), and I'd love to go one or more levels deeper. I can retrieve a list of selected/installed packages ( http://serverfault.com/questions/83456/cygwin-package-management ), but how do I write it back or to a different machine? What I have in mind is when I install a new windows I would like to start with my package list in text form, an apply or inject it somehow to the new system. Where is it? In the registry? In a binary file? in a local database? Or has anybody done this, is there a tool, a tutorial? The essence of what I want is to manipulate the selected package list with something else than the gui. It is ok for me to use the gui for the setup process. So I could imagein manipulating the package List and then run setup.exe and just click through it. Note: I do not want to manipulate the list of already installed packages but of packages that "should be installed". But if htis is not possible, maybe there is some workaround. E.g add an outdated version as installed and the installer will then install the new version.

• Diagnosing Microsoft SQL Server error 9001: The log for the database is not available.

  - by Scott Mitchell

  Over the weekend a website I run stopped functioning, recording the following error in the Event Viewer each time a request is made to the website: Event ID: 9001 The log for database 'database name' is not available. Check the event log for related error messages. Resolve any errors and restart the database. The website is hosted on a dedicated server, so I am able to RDP into the server and poke around. The LDF file for the database exists in the C:\Program Files\Microsoft SQL Server\MSSQL10.MSSQLSERVER\MSSQL\DATA folder, but attempting to do any work with the database from Management Studio results in a dialog box reporting the same error - 9001: The log for database is not available... This is the first time I've received this error, and I've been hosting this site (and others) on this dedicated web server for over two years now. It is my understanding that this error indicates a corrupt log file. I was able to get the website back online by Detaching the database and then restoring a backup from a couple days ago, but my concern is that this error is indicative of a more sinister problem, namely a hard drive failure. I emailed support at the web hosting company and this was their reply: There doesn't appear to be any other indications of the cause in the Event Log, so it's possible that the log was corrupted. Currently the memory's resources is at 87%, which also may have an impact but is unlikely. Can the log just "become corrupted?" My question: What are the next steps I should take to diagnose this problem? How can I determine if this is, indeed, a hardware problem? And if it is, are there any options beyond replacing the disk? Thanks

• Tomcat Custom MBean

  - by Darran

  Does anyone know how to deploy a custom MBean to Tomcat? So far I`ve found this http://www.junlu.com/list/3/8871.html. I copied my jar with my MBean to Tomcat lib directory so the Custom class loader should pick it up. I then followed the instructions but I kept getting the exception below. My MBean does definitely have a public constructor. If I removed the jar from the tomcat lib directory I get the same message which suggests its not picking up my jar or my jar is being loaded after the Apache MBean Modeler is running in Tomcat. 06-Aug-2010 12:14:23 org.apache.tomcat.util.modeler.modules.MbeansSource execute SEVERE: Error creating mbean Bean:type=Bean javax.management.NotCompliantMBeanException: MBean class must have public constructor at com.sun.jmx.mbeanserver.Introspector.testCreation(Introspector.java:127) at com.sun.jmx.interceptor.DefaultMBeanServerInterceptor.createMBean(DefaultMBeanServerInterceptor.java:2 at com.sun.jmx.interceptor.DefaultMBeanServerInterceptor.createMBean(DefaultMBeanServerInterceptor.java:1 at com.sun.jmx.mbeanserver.JmxMBeanServer.createMBean(JmxMBeanServer.java:393) at org.apache.tomcat.util.modeler.modules.MbeansSource.execute(MbeansSource.java:207) at org.apache.tomcat.util.modeler.modules.MbeansSource.load(MbeansSource.java:137) at org.apache.catalina.core.StandardEngine.readEngineMbeans(StandardEngine.java:517) at org.apache.catalina.core.StandardEngine.init(StandardEngine.java:321) at org.apache.catalina.core.StandardEngine.start(StandardEngine.java:411) at org.apache.catalina.core.StandardService.start(StandardService.java:519) at org.apache.catalina.core.StandardServer.start(StandardServer.java:710) at org.apache.catalina.startup.Catalina.start(Catalina.java:581) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.apache.catalina.startup.Bootstrap.start(Bootstrap.java:289) at org.apache.catalina.startup.Bootstrap.main(Bootstrap.java:414)

• Kickstart: Serve dynamic kickstart images via a CGI or PHP script?

  - by Stefan Lasiewski

  I'd like to kickstart a couple dozen RHEL6/SL6 servers. However, some of these servers are different and I don't want to create a new ks.cfg file for each class of server. Are there any products which can generate a Kickstart file dynamically on the fly, from a template? For example, if I append a line like this to the KERNEL: APPEND ks=http://192.168.1.100/cgi-bin/ks.cgi Then the script ks.cgi can determine what host this is (Via the MAC address), and print out Kickstart options which are appropriate for that host. I could optionally override some options by passing parameters to the script, like this: APPEND ks=http://192.168.1.100/cgi-bin/ks.cgi?NODETYPE=production&IP=192.168.2.80 After we kickstart the server, we activate Cfengine/Puppet on this system and manage the system using our favorite Configuration Management product. We're experimenting with xCAT but it is proving too cumbersome. I've looked into Cobbler, but I'm not sure it does this. Update: A roll-your-own solution is discussed in the O'Reilly book: Managing RPM-Based Systems with Kickstart and Yum, Chapter 3. Customizing Your Kickstart Install Dynamic ks.cfg, which echos some of the comments in this thread: To implement such a tool is beyond the scope of this Short Cut, but I can walk through the high-level design. Any such solution would mix a data store (the things that change) with a templating solution (the things that don’t change). The data store would hold the per-machine data, such as the IP address and hostname. You would also need a unique identifier, perhaps the hostname, such that you could pick up a given machine’s data. The data store could be a flat file, XML data, or a relational database such as PostgreSQL or MySQL. In turn, to invoke the system, you pass a machine’s unique identifier as a URL parameter. For example: boot: linux ks=http://your.kickstart.server/gen_config?host-server25 In this example, the CGI (or servlet, or whatever) generates a ks.cfg for the machine server25. But where, oh where, is the code for ks.cgi?

• Virtual Machine Network Architecture, Isolating Public and Private Networks

  - by Mark

  I'm looking for some insight into best practices for network traffic isolation within a virtual environment, specifically under VMWARE ESXi. Currently I have (in testing) 1 hardware server running ESXi but i expect to expand this to multiple pieces of hardware. The current setup is as follows: 1 pfsense VM, this VM accepts all outside (WAN/internet) traffic and performs firewall/port forwarding/NAT functionality. I have multiple public IP addresses sent to the this VM that are used for access to individual servers (via per incoming IP port forwarding rules). This VM is attached to the private (virtual) network that all other VMs are on. It also manages a VPN link into the private network with some access restrictions. This isn't the perimeter firewall but rather the firewall for this virtual pool only. I have 3 VMs that communicate with each other, as well as have some public access requirements: 1 LAMP server running an eCommerce site, public internet accessible 1 accounting server, access via windows server 2008 RDS services for remote access by users 1 inventory/warehouse management server, VPN to client terminals in warehouses These servers constantly talk with each other for data synchronization. Currently all the servers are on the same subnet/virtual network and connected to the internet through the pfsense VM. The pfsense firewall uses port forwarding and NAT to allow outside access to the servers for services and for server access to the internet. My main question is this: Is there a security benefit to adding a second virtual network adapter to each server and controlling traffic such that all server to server communication is on one separate virtual network, while any access to the outside world is routed through the other network adapter, through the firewall, and on the the internet. This is the type of architecture i would use if these were all physical servers, but i'm unsure if the networks being virtual changes the way i should approach locking down this system. Thank you for any thoughts or direction to any appropriate literature.

• Windows 7 pc freezes for an indeterminate amount of time after unlocking

  - by pikes

  Not sure if this type of question is appropriate for this forum, but I've tried everything I can think of to solve this problem aside from format/reinstall. I recently got a new work PC (Dell optiplex 755) with windows 7 professional x64. Standard developer software installed for .net development: VS2008, VS2005, SQL management studio, office 2007, etc. Recently I've been having this weird problem where after I lock my pc, when I try to unlock it, the screen will be black for awhile after unlocking. I can ctl+alt+del and put my password in but then it just goes black. The amount of time on the black screen seems to be related to the amount of time I am away from my PC. If only away a few minutes, it'll take about a minute to get to the desktop. If away for an hour, could take up to 15 minutes. If I lock it and go home for the night, I have to restart my PC in the morning (I've let it sit for an hour after a night of being locked and nothing happened). It doesn't do it every time but definitely the majority of the time. One weird thing I've seen is that if I remote into my machine before trying to log back in it does not do it. I uninstalled all software back to the point when I remember it started happening and it still does it. I was using this PC for a few weeks without this problem happening at all. Anyone know what my next troubleshooting steps could be? My IT department tried to fix it by moving my old profile to another disk and having me log in, effectively recreating a profile from scratch but that didn't solve it. As I said above if this isn't the right forum for these types of questions please let me know. Thanks in advance!

• What is the best way/Software to manage multiple short lived instances of virtual machines ?

  - by Newtopian

  Hi, We have a QA department that have to test our software on multiple combination of OS and DMBS. With Windows spewing out many different versions the combinatorial math of all this can be daunting. So we decided on visualizing our setups but so far it only displaces the problem. The cost of hardware is expensive and we need many different combination far exceeding your server capacity to deliver. Also, these instances are throw away, once the test is complete we no longer need it, furthermore to ensure proper test isolation we should start fresh from a new instance. Lastly we only need a small subset of these system online at any given time. What I am looking for is a way to manage inventory so that our QA staff can order instances to be put online as required and discarded once used. Instances are spawned from a pool of freshly installed systems with the appropriate combination ready to accept our software. It also should be possible for two or more people to start the same instance at the same time, though we could manage without this if it proves too complex to put in place. Finally our budget is pretty thin, we can probably make some purchases but ideally expenditures should be kept to a minimum. To summarize we should be able to : Bring instances online on demand. Ideally should offer queue and scheduling management Destroy instances on demand Keep masters in inventory but not online. Manage large inventory of VMs (30-100 maybe more) with small staff of users (5-10). Allow adding, deleting and changing instances from inventory (bring online, make changes and check back in, or create new and check in). Allow few long lived instances for support tools (normal VM server usage) Thanks for your answers

• Exchange Connector Won't Send to External Domains

  - by sisdog

  I'm a developer trying to get my .Net application to send emails out through our Exchange server. I'm not an Exchange expert so I'll qualify that up front!! We've set up a receive Connector in Exchange that has the following properties: Network: allows all IP addresses via port 25. Authentication: Transport Layer Security and Externally Secured checkboxes are checked. Permission Groups: Anonymous Users and Exchange Servers checkboxes are checked. But, when I run this Powershell statement right on our Exchange server it works when I send to a local domain address but when I try to send to a remote domain it fails. WORKS: C:\Windows\system32Send-Mailmessage -To [email protected] -From [email protected] -Subject testing -Body testing -SmtpServer OURSERVER (BTW: my value for OURSERVER=boxname.domainname.local. This is the same fully-qualified name that shows up in our Exchange Management Shell when I launch it). FAILS: C:\Windows\system32Send-Mailmessage -To [email protected] -From [email protected] -Subject testing -Body testing -SmtpServer OURSERVER Send-MailMessage : Mailbox unavailable. The server response was: 5.7.1 Unable to relay At line:1 char:17 + Send-Mailmessage <<<< -To [email protected] -From [email protected] -Subject testing -Body himom -SmtpServer FTI-EX + CategoryInfo : InvalidOperation: (System.Net.Mail.SmtpClient:SmtpClient) [Send-MailMessage], SmtpFailed RecipientException + FullyQualifiedErrorId : SmtpException,Microsoft.PowerShell.Commands.SendMailMessage EDIT: From @TheCleaner 's advice, I ran the Add-ADPermission to the relay and it didn't help; [PS] C:\Windows\system32Get-ReceiveConnector "Allowed Relay" | Add-ADPermission -User "NT AUTHORITY\ANONYMOUS LOGON" -E xtendedRights "Ms-Exch-SMTP-Accept-Any-Recipient" Identity User Deny Inherited -------- ---- ---- --------- FTI-EX\Allowed Relay NT AUTHORITY\ANON...

• What steps should I take to debug this non-starting hvm virtual machine?

  - by Ophidian

  I have a dom0 machine running CentOS 5.4 with all the latest updates using Xen as my hypervisor. I am using Xen in part because this machine was set up prior to KVM being included in RHEL, and in part because KVM's network bridging configuration is not nearly as simple as Xen's. The dom0 machine is headless and I do all of my VM management via virsh from the command line. I have two hvm domU's: A web server running CentOS 5.4 A mail server running Gentoo Both VM's are backed by LV's on the dom0 but do not use LVM in the domU. Both have virtually identical libvirt configurations (differing by expected things like name, UUID, NIC MAC, VNC port, etc). The web server domU (WSdomU hereafter) does not start since applying the most recent kernel update (kernel-xen-2.6.18-164.15.1.el5.x86_64 and kernel-2.6.18-164.15.1.el5.x86_64 for the dom0 and WSdomU respectively). By 'not start' I mean it appears to be running but it does not use an CPU cycles, does not bring up a graphical console, and does not respond on the network. The WSdomU is listed as no state rather than the normal running or blocked in xentop. The mail server domU starts fine and functions normally. Here are the steps I have taken so far that did not solve the problem: Reboot the dom0 to see if things come up on their own Check xen dmesg on dom0 Check xend logs (a cursory viewing did not show anything blatant; specific suggestions of things to look for would be appreciated) Attempted to connect to the WSdomU's graphical (VNC) console from the dom0 Shutdown the mail server domU and attempt to start the WSdomU Check the SELinux labels on backing LV's (they're the same) Set SELinux to permissive and attempt to start the WSdomU Use virsh edit to try tweaking the WSdomU config virsh undefine, reboot, virsh define the WSdomU config dd the WSdomU LV to an .img file, copy it to my Fedora desktop and run it under KVM (works fine) What steps should I take next to debug this? I will edit in any additional configuration's requested in the comments.

• Motherboard running rather hot while gaming

  - by I take Drukqs

  Case: Antec 1200 Mobo: Gigabyte GA-X58A-UD3R CPU: Intel i7 950 (stock cooler) GPU: EVGA GeForce 570 GTX RAM: 2x 2 GB (4 GB total) DDR3 dual-channel Corsair OS: Windows 7 Home Premium 64-bit This is my first build and it's brand new. I had no problems putting it all together in a few hours one evening and I consider myself to be pretty good with computers. Not to brag or anything like that! Just saying I've been fiddling with them since I was in diapers and I have a good amount of experience under my belt, just not with certain things yet. Recently while playing many of the latest games maxed out without a hitch my motherboard has been running hot and like anyone who's ever built a computer it scares the life out of me. I checked HWMonitor and saw that my motherboard sometimes reached temperatures of around 52 - 78c (the number 78 obviously being what's scaring me). I was wondering if such a temperature is normal and if not what the problem could be. Air flow in my case is phenomenal and besides having to ship back a faulty GPU and reseat my CPU my first build has been a very large success which I am enjoying tremendously. There is literally almost no dust in my case due to it being very new as previously mentioned and my RAM sticks are in the correct slots for dual-channel mode. My cable management is pretty great in my opinion with only cables from my PSU lingering in the bottom of the case. At any given opportunity I ran my cables behind my mobo. Air flow should definitely not be a problem because my CPU only goes up to about 60c and my GPU only goes up to about 80c. Thank you very much in advance.
