• Installing OpenSSL that supports SNI along with previous version of OpenSSL

  - by gh0sT

  So I learned that to host multiple HTTPS websites on the same IP address you need an OpenSSL version that supports SNI (0.9.8f and higher). My RHEL5 box currently has 0.9.8e and Apache version httpd-2.2.26-2.el5. According to a same question here it's not a good idea to replace the original version of OpenSSL and instead to have a parallel installation. It however doesn't explicitly mention how to achieve this. So my questions are: How do I have an alternate installation of OpenSSL without breaking the system? How do I make Apache to use this version of OpenSSL and not the original one? A detailed guide would be extremely helpful.

• Networking Logs for MAC Addresses

  - by NetworkGuy

  I wanted to ask a multi-part question. Does Comcast Cable Internet services record MAC Addresses of the Router behind the cable modem. I know they record it for the modem itself. But is there a way for the Modem/Comcast to relay and keep logs of the MAC ID of the Router itself? Then does a windows operating system Log the MAC ID of the Router when its connected to it? If so where do I locate and purge this? Please let me know all areas where it is Logged within the operating system. Thank you!

• Bank Interleave Requested but not enabled

  - by wbeard52

  I have a ECS A770M-A motherboard with a 2.2GHz Phenom 64 Quad Core processor with 4 gigs of ram. I also have a 1GB DDR3 Zotac GeForce 9500GT video card installed in the computer. I believe the main memory is DDR2. The problem I am having is that I get a "Bank Interleave Requested but not Enabled" error on startup. The computer boots up fine (no error) with the 4gigs of ram if I replace the video card with the previous 256MB video card. I have also tried placing a single gig of ram in the computer with the Zotac video card and still get the error. My question is what would typically cause this error and would a DDR3 video ram be compatible with DDR2 system ram? Thanks

• Linux Alternatives to Lansweeper [on hold]

  - by Mathew MacLean

  I'm new to serverfault, and I'm hoping that this is the correct section of StackExchange for this question. Currently in my network we have a collection of linux fileservers, firewalls, etc. with all windows clients. I am looking for a network management tool, similar to lansweeper that would be able to run on linux servers. I know questions asking for software suggestions are typically frowned upon, but I have looked high and low, and I'm starting to think nothing like this exists. So if anyone could point me in the right direction it would be greatly appreciated!

• Basic proxy with OpenSSH, Cygwin, Putty

  - by clang1234

  I know this is probably a common question, but after looking around for a few hours (on this site and others), I can't find a solution. I'm trying to set up a simple proxy. I already have a server running Windows Server 2008. I've installed Cygwin and have OpenSSH installed. I also have sshd (the openssh daemon) running. Port 22 is forwarded correctly. On my client side I have Putty on a Windows 7 machine. I can successfully open a connection to my server and log in to access the shell. So what do I do next? Do I just name the ports I want tunneled in Putty or do I need to tell my SSH server what to do with those ports? Thanks for the help. Let me know if I left anything out.

• STUN-server using AWS

  - by Yrlec

  We are about to hire some consultants to help us set up an AWS-based server environment that will enable us to handle NAT Traversal for our P2P application. One important part of the NAT Traversal infrastructure is the STUN-server (http://en.wikipedia.org/wiki/STUN). They just told us that in order for the STUN-server to work you must have two public static IP-addresses pointing to the same server. To more specific they said this: It appears that you need 2 static IPs for each server for the STUN to work. Please note, these IPs have to be put into the configuration file, therefore, each time you restart the instance you have to make sure you either use the same IPs or you have to update configuration. As you plan to use AWS for your installation, please confirm that you can have 2 static IP for each server. Our question is if this is possible using AWS and if so, how? If not, do you know any other way to set up a STUN-server using AWS?

• Why does my ReadyNas 4200 have a constant beep post disk failure

  - by swagner88

  Went to check on a high pitched constant beep coming from the server room and discovered that all the LED lights on the disks were black except one which had a constant green. Post a Re-boot nothing changed. Console indicated that that particular drive has failed. Pulled the drive out and BAM everything is fine. Except, the high pitched beep remains. Plan is currently to replace the drive with a new same size drive we happen to have purchased for expansion. My question is, what will this do? Will the NAS accept the new drive as a replacement for the failed one and decide to shut-up? The Manual for the device is almost to straight forward and says that I can just swap drives out as I need but I find that difficult to believe: http://www.readynas.com/download/documentation/HM/RN4200_HW_24May10.pdf

• Using Y split cables to connect two servers to a single PDU receptacle

  - by sagi

  We have bought a few 30amp 208v PDUs that only have 9 receptacles. The servers we are connecting to those PDUs will not use the full 30amps (at 80%, or actually 40% since we use redundant power) so we need to find a way to connect more than 9 servers to the same 9 receptacles so we'll be not wasting capacity that we pay for. I thought about using a Y split cable like this one: http://www.cablesandkits.com/power-cord-c14-c13-splitter-cable-awg-p-515.html That will let me connect two servers to a single receptacle. Each of the individual receptacles can provide 12 amps of power and individual servers are unlikely to consume more than 3 amps at maximal load so it should provide sufficient power. The question is if there is any other reason why this may be a bad idea and if there is any other solution other than buying PDUs with more receptacles (which I don't want to do because I must use horizontal PDU on these racks and ones with more receptacles consume more U space).

• ulimit not reflected for jenkins slave

  - by techastute

  Problem Got java.io.IOException: Too many open files in solr indexing through jenkins. Did some googling and found we have to set the ulimit for the box in where we are running the job. So set the ulimit in a linux box with spec Linux x86_64 GNU/Linux in both of the following fashions ulimit -n 1000000 /etc/security/limits.conf userx soft nofile 1000000 userx hard nofile 1000000 Given userx is the user through which the jenkins job is being executed. when doing ssh to the box as userx manually through terminal and check ulimit -n am getting 10000000 Question But when executing the same ulimit -n through a jenkins job, only getting 1024 which is the default. Any advice would be much helpful?

• Offset the tickmarks of a secondary axis

  - by Dan

  I would like to offset the tickmarks of a secondary axis in excel WITHOUT changing the minimum. Here is a very complicated VBA class that apparently solves the issue but I would like a solution that doesn't require me to construct my entire chart in VBA. Here is an example of what I mean (I removed the chart insides so it looks funny, but really only the axes matter for this question): I am happy with the primary axis on the left. The secondary axis is just the primary axis plus 7.96%, so the secondary axis HAS TO have 0.0796 as a minimum. But I would like my tickmarks to be at nice rounder numbers so I would like to offset the starting point of the secondary axis' tickmarks to only start at 8%. Does anyone know of a way to achieve this? Just to be clear about the VBA, I am happy to use a VBA solution but I don't have the time to actually construct the chart itself in VBA. Using VBA to get a handle on the chart and make the adjustment would be perfect.

• Domain Controllers group not reflected in domain controllers credentials

  - by Molotch

  I set up a small testlab in vbox consisting of four servers. Two domain controllers dc01, dc02, one offline root ca and one online enterprise sub ca, ca01. All servers are based on Windows Server 2008 R2 Standard. Everything works as excpected except one thing. If I issue a certificate template with read, enroll and autoenroll rights to the security group "domain controllers" it does not let dc01 or dc02 to enumerate or enroll for the certificate. I've restarted both domain controllers several times to update their credential tokens with the correct group memberhips. So I added dc01 to the "domain computers" group and gave that group read, enroll and autoenroll rights in the template, bam, the certificate was issued. So my question is, why isn't the domain controllers group memberhips reflected in the domain controllers (dc01 and dc02) credentials? Can I view the computers credentials somehow and how should I go about trying to resolve the issue?

• Can I delete EFI System Partition without harming other data on drive?

  - by Andy

  I have three external HDD's in a USB enclosure. After a recent upgrade to Win7, during which these three drives were actually installed inside the PC tower, two of the three drives now have a 200MB EFI partition, and the two drives do not show up as usable drives under either Win7 or Snow Leopard. One of the drives is empty; the other one, however, has a bunch of stuff on it that I want to save if possible. My question is, how can I get back to this data? Can I simply delete the EFI partition, and all will be well? Or do I have to do something trickier? Or am I just hosed?

• Google Contacts and Mac OS X Address Book

  - by dyve

  The sync that Google offers for Google Contacts < Mac OS X Address Book is seriously flawed. It doesn't sync automatically, it doesn't sync all contacts, it doesn't sync all fields. See here for a list of warnings and issues. Is there a better way to sync Google Contacts to Mac Address Book bidirectionally? Preferably free, and preferably without adding extra software. I have tried to do it through Plaxo (which has an excellent Mac Address Book sync, albeit through an extra software install), but Plaxo doesn't handle Google Sync well (no updates). UPDATE: For the new Mac OS X Snow Leopard this shouldn't be an issue. This question is looking for a Leopard answer.

• Prove this Tautology (No Truth Tables)

  - by FSM

  This is for homework for my Discrete Math class. I understand how to prove tautologies with a truth table. I'm having trouble figuring out how to do it without though. I found this example in our text, but the solution is not provided. I was hoping someone could answer it as best they could so I could apply it to my other questions. Thanks! ! = not/invert ^ = and V = or - = if then [!P ^ (P V Q) ] - Q I also am completely lost for this question (I fear I'll be tested on something of this difficulty) [ (P - Q) ^ (Q - R) ] - (P - R) Thanks for the help all!

• How to make computer interface with circuit

  - by light.hammer

  I understand that I can build a circuit that will do whatever I like (ex: a simple circuit that will turn on a motor to open the blinds or something), and I can write a program that will automate my computer/mac however I like (ex: open this program at this time, or with this input and create a new file, ect). My question is, how can I interface the two? Is there an easy DIY or cheap commercial (or not cheap but functional) USB plug that will turn on/off from computer commands? I'm basically looking for some sort of on/off switch I can script/applescript. How would you even approach this problem, would I have to write my own driver some where along the way?

• Is there an RSM replacement in Windows 7? (to eject USB and Firewire devices from command line)

  - by Jay

  I know Windows XP and previous had an rsm.exe file in the <root>\windows\system32 folder that could be used to manage media. I used this command in batch files and from the command line to eject external disks (iPod, CF cardreader, etc.). This utility appears not to be included in Windows 7, and I wonder if there is some replacement utility that will allow the same thing. I've been unable to find any such thing. I'm aware of the 3rd party utilities; this question is only about what is included with Windows 7.

• GnuPG PHP gnupg Folder & Files Permission

  - by Michael Robinson

  Situation: we plan on using PHP's GnuPG extension to encrypt/decrypt files. Currently we've setup some test cases, using keys generated with GPG. The generated files reside in: /Users/username/.gnupg/ I am able to get keyinfo for the key I want to use to encrypt/decrypt, but when I attempt to use addencryptkey, I get: (E_WARNING: 2): gnupg::addencryptkey() [gnupg.addencryptkey]: get_key failed I think this is due to the permissions on the ~/.gnupg folder & enclosed files. The files are owned by me - username, but apache runs as www. A few days ago I did have this working, but it seems each time I use GPG Keychain Access to import / export a key, the folder's permissions are changed. Question: What are the exact permissions required to allow PHP's GnuPG to add encrypt & decrypt keys?

• Why can't I resize some virtual thick disks in VMWhare vSphere Client

  - by Paul-Jan

  Let me start off by mentioning I am really really new to this whole VMWare ESX/vSphere thing, so apologies if this is a FAQ or asked a million times before using better wording. Also, please correct me if I'm using the wrong terms all over the place. We just got this brand new VMWare EXS server, and we started importing virtual machines from around the office. Some of them were originally based on VMWare, others are converted from MS Virtual Server. One of these machines needs a bigger disk, but in the vSphere Client the disk size spinedit is disabled. Disk type is thick. However, for other machines, with the same disk type, the spinedit is enabled and I can happily resize their disks. So here is the question: why can't I resize this disk in particular? All machines are freshly converted, so I assume there are no snapshots yet, which I read would stop a resize from happening (again, correct me if I'm wrong).

• "powershell has stopped working" on PS exit after creating IIS User

  - by Nick Jones

  On a Windows Server 2012 box, I'm using PS to create a new IIS User (for automated deployments using MSDeploy). The command itself appears to work fine -- the user is created -- but as soon as I exit my PowerShell session (typing exit or just closing the command window), a dialog is displayed stating "powershell has stopped working", with the following details: Problem signature: Problem Event Name: PowerShell NameOfExe: powershell.exe FileVersionOfSystemManagementAutomation: 6.2.9200.16628 InnermostExceptionType: Runtime.InteropServices.InvalidComObject OutermostExceptionType: Runtime.InteropServices.InvalidComObject DeepestPowerShellFrame: unknown DeepestFrame: System.StubHelpers.StubHelpers.GetCOMIPFromRCW ThreadName: unknown OS Version: 6.2.9200.2.0.0.400.8 Locale ID: 1033 The PS commands in question are: [System.Reflection.Assembly]::LoadWithPartialName("Microsoft.Web.Management") [Microsoft.Web.Management.Server.ManagementAuthentication]::CreateUser("Foo", "Bar") Why is this happening and how can I avoid it? EDIT: I've also confirmed this be a problem with PowerShell 4.0, so I've added that tag. I've also submitted it on Connect. UPDATE: It appears that Windows Server 2012 R2 does not have this same bug.

• Trouble configuring firewall for FTP on Windows Server 2008 R2

  - by x3ro

  Ok, I'm having the exact same problem as in this question http://serverfault.com/questions/59635/outbound-ftp-on-server-2008-r2-stalls but the accepted answer didn't help me much... I followed the third step of this http://learn.iis.net/page.aspx/309/configuring-ftp-firewall-settings/ guide in order to configure my firewall for FTP, and I am able to authenticate, however, the data channel doesn't seem to be passing through the firewall. If I disable the firewall, everything works fine. Hope someone can help me, as this is really starting to annoy me. Best regards, x3ro

• Very High Interrupt CPU usage in Win2k3 VM on vSphere

  - by Darragh

  Hi, I've been testing some software in a server virtual environment and I've noticed I get a huge amount of CPU usage on the Interrupts process. My question is, how does this relate to the virtual hardware platform as the rate is allot lower in a real system. Some how the hypervizor scheduler works hard to over come this problem but not as well as on real hardware does. Obvious things are high I/O and disk access but this application mostly just sits and works in memory allot. If anyone has experienced the same, please let me know. thanks in advance Screenshot: Process Explorer

• How to get infected with Antivirus 2010

  - by PHLiGHT

  I know that this is the exact oposite of the question most people ask as it is a royal pain to remove. I hope this isn't flagged as me wanting to infect other people. I know my mom almost installed it but it was running firefox so she unknowingly downloaded it 10 times but didn't install it. I have since deleted those files and have been wondering what to look out for on sites that carry the virus. I'd like to test out AV software in a VM environment. It has been getting past our AVG as of late. Thanks,

• CHM to EPUB Converter

  - by griegs

  I recently bought an iriver ebook reader but it doesn't support chm files. I have bought a bunch of O'Reilly books and with them have the soft copy as well. Some books convert quite well using calibre. However, there is one book I have that just won't convert. So I used HH to decompile it and now I have a bunch of html files. These html files contain references to images in folders. How can I now join them all into a single document which Calibre can read and properly convert into an epub or am I going about this the wrong way? I've read this question but it removes the images and the images are quite important to the content.
