• Ejabberd Clustering on EC2

  - by Architact

  I am trying to implement ejabberd clustering on Amazon EC2 instances, I have installed ejabberd and it is working fine on both instances, I can connect and send message, my first server is a master server and has the FQDN of master.example.com, second server is a slave and has FQDN of slave.example.com. I have edited the ejabberdctl.cfg file on both instances changed INET_DIST_INTERFACE on both instances to the value returned by ifconfig changed ERLANG_NODE to [email protected] on master and [email protected] on slave. Now when I run this command on slave net_adm:ping('[email protected]'). it always returns pang response indicating that it can't reach the master server. I am looking for possible fixes for that. Things already done Both master and slave domains are pointing to their instances I even tried allocating elastic ip and assigning that to instances, but did not help either. Any help will be greatly appreciated.

• Connect to CentOS LAMP instance from Windows PCs

  - by Gnanesh

  I have a CentOS 6 machine running on our network which has a simple LAMP installation on it. I have some files there which I would want to access through other Windows PC which I am able to do so using the IP address of the CentOS machine. Since the IP address of the CentOS machine also could be dynamic I would want to connect to it using the computer / host name But I am not able to do so using the computer / host name of the CentOS machine. Can someone help me point out what I may be missing and help me out to resolve this?

• Stress test a server for simultaneous connection

  - by weston smith

  I am trying to figure out a practical way to stress test a server for 300 to 600 simultaneous connections. Any advice? Thank you everyone for the help. To be more specific (sorry I wasn't before) this is a Flash Media Server on AWS that will be streaming live video. I've been having problems with the video freezing/buffering for everyone and I need to verify if its on the user end, upload end, or server end. I mainly need help with stress testing the server with 300-600 multiple request before going live.

• Computer wakes itself few seconds after hibernation

  - by Juan Zamudio

  Hi all, this is the situation, this is a Dell Optiplex 755, I recently upgraded it to Windows 7 64 bits, it had Windows XP SP3 previously, on XP I never had a problem hibernating the PC, now with Windows 7 64 every time I hibernate the PC it wakes it self after 5 or so seconds. Here are the steps I already tried: On Windows 7 I enabled the hibernation following this steps In the MoBo the sleep settings are on S3 In the Mobo I disable remote wake ups I have disabled the remote wake up in the NIC When I run the lastwake command I get unknown device or something like that I already disable the wake timers on Windows I have the latest drivers from Intel, but I just found out that in the device Manager I get a warning sign on the "Intel AMT SOL (COM3)" device saying that it failed and windows stopped the device, I reinstalled the Intel drivers but nothing changed. The only thing that I haven't touch is Intel ME in the MoBo but I don't if that could help and what settings are correct. Thanks for you help.

• How do I set "MaxPermSize" for Atlassian Fisheye/Crucible running as service on Win2k3?

  - by Jeremy

  I have been trying to setup Atlassian Fisheye/Crucible as a service on Win 2K3 R2 for two weeks. I keep getting various "java.lang.OutOfMemoryError: PermGen space" errors, which crash Fisheye and force me to restart the service. I've followed the example on the Atlassian support site to configure MaxPermSize within the service wrapper. However, when I check SysInfo inside the Fisheye Admin pages and the debug log, I don't see any confirmation. The Java Heap info is in both places, so I'd expect the MaxPermSize setting to show up in both places. The error is persisting and Atlassian support has been little help. I appreciate any help.

• Installing the Apple Root Certificate Authority on CentOS CLI

  - by Daniel Hollands

  I could be barking up the wrong tree here, but I'm looking for help on installing Apple's Root certificate (http://www.apple.com/certificateauthority/) on a CentOS server via the command line - which I need to send messages to their APNS system. The code I'm using for this purpose is a variation on this: https://github.com/jPaolantonio/SimplePush/blob/master/simplepush.php - which works perfectly well on a Windows server, but as soon as we try to use it on a CentOS one, it falls over. We're lead to believe this has something to do with not having the CA installed on our CentOS box - but all efforts to do so have failed. As the CentOS server is headless, we need the ability to do this via the commandline. Can someone help?

• importing old .eml files int outlook 2010

  - by Duncan Kenworthy

  I was having so many problems with my laptop & Windows vista that I have updated to Windows 7 64bit. Because I was having so may problems I wanted a 'clean' upgrade so didn't want to carry over any programs or settings. Prior to changing over I saved all the folders I wanted from MS mail to a separate drive and then updated to Win 7 and Office 2010. To my horror I don't seem to be able to import my .eml messages into Outlook which means all my mail is in limbo. Please can anyone help me to simply import my old inbox messages into my new inbox as I have given up trying using the import/export menu as there doesn't seem to be a choice that works. Help!! Not too good a nerd!

• Broadcom HT1100 SATA controller not working properly with 1TB drives

  - by Jeff C

  I've been using RHEL distro's for several years and always managed to find the answers until now. I know this is more of a hardware issue, but I've been working on this for over a week and trust Linux and the IT community to help more then HP. I have CentOS 6.3 installed on an HP ProLiant DL145 G3 server with the BroadCom HT1100 IO controller and ServerWorks SATA Controller MMIO BIOS v3.0.0015.6 Firmware. This controller does not support large drives fully. Here's what I've tried and the results; Stock setup - Freezes on the ServerWorks POST screen. Can't even enter CMOS without disconnecting the drives. If I simply disconnect the SATA cables before it gets to the ServerWorks screen and reconnect afterwards I can boot from a CD, USB, PXE fine. However fiddling with cables at ever boot isn't practical. If I enter the BIOS config I can set it to not try booting the drives but leave the controller enabled. This lets me boot normally but the drives are not visible in the OS (live CDs or USB installed). I used method #2 to install and update CentOS. I have the /boot partition on a USB drive (everything else is on the SATA drives in software RAID1) hoping that would work around the issue but I get this Kernel panic - not syncing:Attempted to kill init! Pid: 1, comm: init Not tainted 2.6.32-279.9.1.el6.x86_6 #1 Call Trace: [<ffffffff814fd6ba>] ? panic+0xa0/0x168 [<ffffffff81070c22>] ? do_exit+0x862/0x870 [<ffffffff8117cdb5>] ? fput+0x25/0x30 [<ffffffff81070c88>] ? do_group_exit+0x58/0xd0 [<ffffffff81070d17>] ? sys_exit_group+0x17/0x20 [<ffffffff8100b0f2>] ? system_call_fastpath+0x16/0x1b panic occured, switching back to text console I'm sure it should be possible to talk to the drives without the BIOS boot check since the BIOS doesn't see them in method #2 either, their disconnected when it checks, but Linux sees them fine. If anyone could help figure out how I would greatly appreciate it! The other possible option I've come across is a complex firmware update. Tyan has a few boards on their website with the HT1100 and a ServerWorks v3.0.0015.7 update which says "adds support for TB drives" in the release notes. If someone could help me get the Tyan SATA firmware into the HP ROM file so I could just reflash that would also be very much appreciated. Thanks for any help you guys can offer!

• Using unsigned drivers in Windows 8

  - by T. Fabre

  I just migrated from Windows 7 x64 to 8, but I can't get my VPN software to run anymore : the SafeNet IKE service (installed by SafeNet SoftRemoteLT GA, used by my VPN provider) cannot start anymore. I found that by default unsigned drivers are disabled on Win8, and that is what is blocking the driver. The System event log tells me that the driver (apparently, C:\WINDOWS\SysWow64\Drivers\IPSECDRV.sys ) was blocked when I try to manually start the service (SafeNet IKE Service). I get the same messages for another driver, crypto.sys found in the same folder. I tried using bcdedit to enable unsigned drivers : bcdedit /set loadoptions DDISABLE_INTEGRITY_CHECKS bcdedit /set testsigning ON After reboot, same error. I tried by booting into Win 8's test mode, same issue. Applying the code signing policy (Enabled, Ignore) does not help either. Running gpresult does show that the policy is applied. Any help welcome.

• Superscope DHCP leases and configuration set up

  - by Vdub

  Hello I wanted to see if someone could help with a network problem I am having. Right now we have a super-scope and scopes of 192.168.50.1 and 192.168.51.1, as of now both are activated but only 192.168.50.1 is handing our leases, 192.168.51 wont. here is a summary of our network Gateway: watchguard firebox x750e for our router/gateway at 192.168.50.1 I set up as a secondary IP address 192.168.51.1 Server: Server 2008 r2 standard, running our DNS @ 192.168.50.242 and 8.8.8.8 as a secondary, AD, and DHCP. On that NIC card i have 192.168.50.242 as the IP address and 192.168.51.242 as a secondary. 192.168.50.1 as the default gateway and 192.168.51.1 as a secondary. Im am not very knowledgeable at this but as far as i have researched after adding a super scope and activating scopes, they should automatically start handing out addresses and I cant figure out why only one does. any help at all would be appreciated.

• How to set umask for a folder and it's subfolder?

  - by Cyril N.

  I'm working on the same directory with some friends and they access it via SSH. I added us in the same group and defined a sticky bit to keep the user:group values the same. But when a user create a file/folder, the Write attribute is not defined for the group, disabling other to write it/on it. How can I define the Umask to add the Write value for groups in the specific directory and it's subfolders ? I tried to find some help before, but I only saw helps for Fedora/CentOs, and I'm using Debian Squeeze. Thanks for your help

• How Can We Create Blackbox Logs for Nginx?

  - by Alan Gutierrez

  There's an article out there, Profiling LAMP Applications with Apache's Blackbox Logs, that describes how to create a log that records a lot of detailed information missing in the common and combined log formats. This information is supposed to help you resolve performance issues. As the author notes "While the common log-file format (and the combined format) are great for hit tracking, they aren't suitable for getting hardcore performance data." The article describes a "blackbox" log format, like a blackbox flight recorder on an aircraft, that gathers information used to profile server performance, missing from the hit tracking log formats: Keep alive status, remote port, child processes, bytes sent, etc. LogFormat "%a/%S %X %t \"%r\" %s/%>s %{pid}P/%{tid}P %T/%D %I/%O/%B" blackbox I'm trying to recreate as much of the format for Nginx, and would like help filling in the blanks. Here's what Nginx blackbox format would look like, the unmapped Apache directives have question marks after their names. access_log blackbox '$remote_addr/$remote_port X? [$time_local] "$request"' 's?/$status $pid/0 T?/D? I?/$bytes_sent/$body_bytes_sent' Here's a table of the variables I've been able to map from the Nginx documentation. %a = $remote_addr - The IP address of the remote client. %S = $remote_port - The port of the remote client. %X = ? - Keep alive status. %t = $time_local - The start time of the request. %r = $request - The first line of request containing method verb, path and protocol. %s = ? - Status before any redirections. %>s = $status - Status after any redirections. %{pid}P = $pid - The process id. %{tid}P = N/A - The thread id, which is non-applicable to Nignx. %T = ? - The time in seconds to handle the request. %D = $request_time - The time in milliseconds to handle the request. %I = ? - The count of bytes received including headers. %O = $bytes_sent - The count of bytes sent including headers. %B = $body_bytes_sent - The count of bytes sent excluding headers, but with a 0 for none instead of '-'. Looking for help filling in the missing variables, or confirmation that the missing variables are in fact, unavailable in Nginx.

• Server problem (duh)

  - by j-t-s

  Sorry the title couldn't be more specific. I installed Abyss Web Server. I'm running Windows XP Home Edition and I have Wireless Mobile Broadband internet. I used to be able to access (and other people on other networks) my site by entering my ip address in the browser, but after I formatted, and the installed abyss web server again, this does not work anymore. There are no errors. I CAN visit my own site by entering my ip address BUT anybody else can't do the same, it just says "connecting" in the browser's statusbar and it never changes. I have consulted the docs and have found no help. Google hasn't helped with this problem either. Can somebody please help? Thank you :)

• cheapstuff.com malware

  I left my computer off for a couple of weeks and since my Windows 7 updates have been installed I have managed to gather a malware virus. It tries to redirect me on almost all websites I go to. I have read many ways to solving this issue manually, but it seems difficult and I dont want to delete any important files by mistake. All the instructions I have read seem complicated and generic all leading to a company that say they can help remove it. Is it their scam?? Can anybody help by giving me any free software or a descriptive run through for beginners of how to manually remove it? cheers guys

• Unable to access a registry key

  - by gix

  I wondered why some file associations were broken and stumnled upon a nasty problem: I cannot access the key HKEY_CURRENT_USER\Software\Classes. As you can see above, I cannot view its current permissions, nor its owner (which should by SYSTEM). And no matter what I tried I'm unable to fix it. Trying to change the owner gives me a permission denied (also when trying from the Administrator account). RegDacl, which seemed to help another user, also aborts with a permission denied error. Any suggestions how to repair this? If I cannot repair this I guess I have to dump that user account and create a new one. Are there any "diff-like" tools out there to help copy over registry keys?
