  • Good low-cost SSL certificate providers

    - by phenry
    We need an SSL certificate to facilitate remote access and administration by a small number of employees. I don't want to have to train a bunch of non-technical users to install a self-published cert on their home computers, so I'd prefer to purchase one from a well-trusted provider. We won't be using it for any kind of e-commerce or things like that, so it seems hard to justify paying the prices demanded by some of the big-name providers. Who are some good low-cost providers to consider? What are the important differences between the offerings that are available at different price points? (And is the certificate business really as much of a racket as it seems?)

  • Mercurial SSH process blocks when run from Local System

    - by Liedman
    We are using Mercurial over SSH for our development. We use Hudson for continous integration, and have deployed it on Tomcat, running on a Windows 2003 Server using the Local System account. Mercurial is configured to use Putty's plink.exe as its ssh command in Mercurial.ini, together with a private key for SSH authentication. When Hudson attempts any Mercurial command over SSH, the operation just blocks. I can see the three processes being started: hg.exe, cmd.exe and plink.exe. On the remote machine, I can also see the SSH session being opened and the authentication key being accepted. After that, nothing appears to happen, and everything just blocks, seemingly forever. (As a side note, subversion/SVN over SSH works from Hudson to the same server, using the same user and authentication key). A solution would of course be the best, but at least a hint for how I should debug it to get further would be nice, since I'm stuck and haven't even got an error message right now.

  • ECC RAM in GA-G33M-DS2R? Or any Gigabyte/G33M motherboard?

    - by Gregory Hoerner
    I'm looking to retire a server which has 12GB of ECC DDR2 RAM. I'd like to upgrade my multi-purpose machine (firewall, file server, VM host for Windows Home Server, etc.) using the RAM from the server. I was just wondering: Has anyone had experience using ECC RAM in a GA-G33M-DS2R motherboard (or any Gigabyte GA-G33M-XXXX motherboard for that matter)? Has anyone had experience using ECC RAM in a motherboard with a G33M chipset. I've searched everywhere and found the attitude positive of ECC memory working in a Non-ECC board, but I would like some specific positive feedback before proceeding tonight. I have to kick the entire house offline, which I don't like to do without good reason :)

  • Able to connect by SSH, but not x2go

    - by Mike
    I am having trouble connecting to a remote server with X2GO using a DSA key. Connecting works fine over SSH, but when I try to connect with X2GO, it goes immediately to the username/password box and doesn't want to use the private key I specify in the options. If I select "Try auto login" it appears to try to connect and then I get the following error: No public key matched Access denied. Authentication that can continue: publickey It was working previously, but I reinstalled the client OS and since then I am unable to connect. I copied all of the SSH keys over from the previous installation. I also tried deleting my ~/.ssh/known_hosts file and adding the key to ssh-agent with no success, but the key is definitely added correctly: $ ssh-add -l 1024 b9:3d:e5:ef:48:ea:fc:c6:6e:45:89:b5:35:e7:58:39 server.com_dsa (DSA) Note, if I enable password authentication on the server, I can connect fine, however I would like to use publickey. Any ideas how I can connect with public key authentication?

  • Configure Postfix to send emails "via" a server [migrated]

    - by Zach Russell
    This is a question related to postfix and WordPress (but is more of a postfix question). To give some background, on a professional WordPress host (like WP Engine) when I receive WordPress Mail Notifications (comments, form submissions, new users, etc...) it will say in gmail sent from "predefined wordpress admin email" via email.wpengine.com. This is not blocked by Google's spam filters or anything. I have a cloud server set up and a WordPress site installed on it. When I send email from [email protected] it gets sent to spam and when I send email as [email protected] (me) it fails to send completely. This does, however send fine on WordPress. This goal of this it so send all emails via mail.wptemple.com and have them not get caught by spam filters. How can I accomplish this?

  • SNMP: how to get combined output of memBuffer, memCached and memAvailReal?

    - by user492160
    Below is the output of 'free -m' on my system: total used free shared buffers cached Mem: 2026 1936 90 0 212 649 -/+ buffers/cache: 1074 952 Swap: 3359 0 3359 I'd like to retrieve the value 952 of -/+ buffers/cache using 'snmpwalk'. This is for integrating 'free memory' availability with Cacti-poller. But currently the only values available are: # snmpwalk -v 1 -c public localhost .1.3.6.1.4.1.2021.4 UCD-SNMP-MIB::memIndex.0 = INTEGER: 0 UCD-SNMP-MIB::memErrorName.0 = STRING: swap UCD-SNMP-MIB::memTotalSwap.0 = INTEGER: 3440632 UCD-SNMP-MIB::memAvailSwap.0 = INTEGER: 3440576 UCD-SNMP-MIB::memTotalReal.0 = INTEGER: 2075556 UCD-SNMP-MIB::memAvailReal.0 = INTEGER: 92552 UCD-SNMP-MIB::memTotalFree.0 = INTEGER: 3533128 UCD-SNMP-MIB::memMinimumSwap.0 = INTEGER: 16000 UCD-SNMP-MIB::memShared.0 = INTEGER: 0 UCD-SNMP-MIB::memBuffer.0 = INTEGER: 217388 UCD-SNMP-MIB::memCached.0 = INTEGER: 664904 UCD-SNMP-MIB::memSwapError.0 = INTEGER: 0 UCD-SNMP-MIB::memSwapErrorMsg.0 = STRING: Is it possible to retrieve the combined value of memBuffer+memCached+memAvailReal using snmpwalk for graphing with Cacti and RRDTool? If not what options do I possibly have? I'm using net-snmp 5.3.2 on my agent host. Thanks in advance.

  • What is causing a vm to exhibit packet loss?

    - by d03boy
    We have a pretty nice piece of hardware set up to run multiple virtual machines in vmware and one of the vm's is an instance of Windows Server 2003 running SQL Server 2005. For some reason we occasionally see 10-20 seconds of straight packet loss to this machine from remote machines (my workstation) as well as other vm's on the same physical hardware. I am using PingPlotter to keep a close eye on the packet loss. So far we've turned off flow control on the NIC but we are already running out of other things to try. What might be causing this and how can I identify the problem? Note: We also have another server with a very similar configuration with the same type of problem to a lesser extent (because its not used as heavily?)

  • How to emulate wireless in Virtualbox?

    - by huahsin68
    I have WinXP install in virtualbox which host in Linux. I have a TP-Link (TP-WN321G) USB wifi adapter and have the driver installed inside WinXP. When I plug-in the wifi adapter, there is an option show "Ralink 802.11g WLAN [0101]" in the virtualbox's USB icon, tick on that option, the Device Manager able to detect the hardware which shows TP-Link, but when look into the properties, it says there is no driver was install. I did try to install Ralink driver but still no luck. Just curious why my wifi adapter is TP-Link, but the option show Ralink? May I know how can I emulate the wireless network inside WindowsXP?

  • Why are all the tabs except MBeans disabled in JConsole?

    - by Kem Mason
    I'm trying to connect to JConsole on a server running: java version "1.6.0_0" OpenJDK Runtime Environment (IcedTea6 1.4.1) (6b14-1.4.1-0ubuntu12) OpenJDK 64-Bit Server VM (build 14.0-b08, mixed mode) from my local machine, running: java version "1.6.0_24" Java(TM) SE Runtime Environment (build 1.6.0_24-b07-334-10M3326) Java HotSpot(TM) 64-Bit Server VM (build 19.1-b02-334, mixed mode) When I connect to jconsole on the server, all the tabs except the MBeans tab are disabled. If I run the same application on my local machine, and use jconsole to connect to it there (using the remote interface still), all the tabs are enabled just fine. Everything I have seen only suggested the possibility that the server was 1.4 or earlier.

  • Mysql out of disk space

    - by Paddy
    I have just finished developing a rails app which has a mysql db as a backend. The app is meant for high traffic and will store lots of information. I am planning to set up my own web server and host the site from it. If in future my disk space runs out i would want to expand by adding more space. But say if my mysql database is housed in my /disk0s1 and by adding a new drive i have more partitions (and hence more disk space), how then would i extend my database to store information on those partitions too, and at the same time prevent any information from being written on the original partition. Should i go for multiple databases? if so how? If i went for a hosting solution i wouldn't be bothering about this as i would just have to worry about making payments for the extra space :) I always wondered how space is added on-the-go by these webhosts. Is there any specific mysql configuration that i have to make?

    - by Vladimir Kadalashvili
    I'm trying to connect to connect to OpenVPN server from my Ubuntu 11.10 machine. I use the following command to do it (under root user): openvpn --config /home/vladimir/client.ovpn Everything seems to be OK, it connects normally without any warnings and errors, but when I try to browse the internet I see that I still use my own IP address, so VPN connection doesn't work.

  • Linked vSphere servers preventing cloning?

    - by brian
    I've currently got a pair of vSphere5 standard servers (physical, not VAs) managing about a hundred ESX 4.1 and 5 hosts in two different physical and logical datacenters. With our last purchase, we bought another vSphere license for the new vS server. I unmanaged all the ESX servers in one datacenter and added them to new vSphere server. Our previous single-vS-server layout used to be: -vSphere1 --Datacenter1 (where the physical ESX host was located) ---Folder ----ESX server1 --Datacenter2 ---Folder ----ESX server2 Now it looks like -vSphere1 --Datacenter1 ---Folder ----ESX server1 -vSphere2 (new vSphere server) --Datacenter2 ---Folder ----ESX server2 ESX server2 was removed from vSphere1's inventory and added to vSphere2's, so it is now managed by vSphere2. This is nice and all, as no vSphere <-- ESX management traffic leaves the physical datacenter, except for one huge oversight: when I go to clone a VM, the opposite vSphere server (and thus other datacenter) does not show up in the list on the first page of the wizard. Is this a bug, a license limitation, or is it just simply not possible to clone a VM from an ESX box managed by one vS server to another ESX box managed by a /different/ vS server?

  • Redirect folder to different server

    - by yuval
    Just for clarity, I already posted this on StackOverflow and got advice that this better fits in ServerFault.com so here goes: I know you can redirect subdomains to a different server, but can you do the same with folders? Say I have example.com. I can redirect mysubdomain.example.com to a different server, but can I redirect example.com/mysubdomain to a different server? I'd like to host a rails app in that folder on a site that runs php while still maintaining good search engines ratings (by not creating a sub domain which in my experience in recognized as a different site). Any help? Thanks!

    - by Eliot Rocha
    Well i was using the info on this: Puppet - Any way to copy predefined custom configuration files for software on clients from the puppet master (host)? But i need some more elaborated, because i have several Desktops and are in use by 2 or 3 users each one, so i want to make a class for copy a shortcut in his desktops. The computers are joined to a domain, so any user can log in any desktop, and his profile is created in every desktop. I've tryed with this: class applink { file { "/home/installer/Escritorio/Workdesktop.desktop": owner => installer, group => root, mode => 770, source => "puppet://$server/files/Workdesktop.desktop" } This is only for one user called "installer", how can do this for several users? Can i use $USER for do this? Any Thoughts? Thank You!

  • HTTP Headers - need to check OPTIONS

    - by chris
    I've received the results of a pen test and there is some unwanted exposure in the HTTP OPTIONS where the fact that Frontpage Server Extensions was available (now removed) was reported. I need to run a check on the OPTIONS to see whether it has been removed. The test output from the report is below, I need to recreate it to establish that it has gone but don't know how to check the OPTIONS, I can only find tools that seem to check the "HEAD / HTTP/1.1". Does anyone know how to test this - I'm running a Windows environment?

Is this a server side problem? because so many browsers cant be wrong at same time on Windows.

  • Automatically Login & Startup A Windows Program On Amazon's EC2 Service

    - by darkAsPitch
    How can I automatically start a program on Amazon's EC2 Windows 2008 web servers? For example, if I wanted to test the "Digg effect" on a web page of mine, how could I open 100 windows 2008 servers at once, each loading one (or two?) instances of the firefox web browser? I have placed a sample batch file in the windows startup folder that echos the time it was called, but it is only started when I actually login remotely via the remote desktop protocol. I don't want to have to login to 100 servers to get my software to run :P What can I do? I am using this Windows 2008 Datacenter, Amazon-supplied AMI specifically: ami-a2698bcb

  • Growing the size of a VM's disk in VMware

    - by soandos
    I have a VM that I originally gave 10 GB to (using VMware workstation, and Ubuntu 11.10 is the guest OS). I now wish to add to that. I have seen the option to expand the disk size, but all that does is create a new "partition" that Ubuntu can see. Is there a way to expand the size of the primary partition that the guest OS is using? NOTE: I have seen something regarding doing this for a regular Ubunbu OS that requires a boot disk. Is there a way that I can apply that to this VM case? Using Windows 7 64-bit as the host OS EDIT: To be clear, I am trying to resize the boot partition. Edit 2: GParted's resize option is greyed out.

Any ideas? Note: There is no option via a provided control panel to add this, it's a basic package I purchased I know this post answers it but there are no extra comments and I'd like to know if it's the best way: way to redirect page to www using virtual host configuration in sites-available for apache2?

  • VNC over SSH on open Tunnel

    - by Joey Bagodonuts
    Is it possible to bind VNC server to a open SSH tunnel? I have a tablet that has initiated a reverse ssh tunnel to my server. This works fine over port 8080. I need to now bind to this port from my local machine. It looks like Ubuntu has some "remote desktop viewier" that has ssh built in capabilities so I assume the only thing I need to do now is figure out how to bind the tablets VNCserver to the open SSH tunnel. Is this possible? Thanks

    Thnaks for reading. I setup a VPN server on my Buffalo WHR-HP-G300N router at Macau, and use it for access website over China Firewall when i travel in China. On Android and Windows, everything work fine, however on my Macbook Air and iPad, it is not working. I can access blocked site like badoo.com but not facebook and youtube. If i ping it at terminal, it said "ping: cannot resolve facebook.com: Unknown host". After i read this http://cp.hidemynet.com/knowledgebase.php?action=displayarticle&id=26, i find i can restart my router and reboot my Macbook, and connect to VPN before any request to any blocked site so that i can successfully connect to facebook and youtube. However it works sometime but not always. It is really annoying because i need to work on VPN and my Mac, would anyone can help me to solve it? Rather than restarting my router and my Mac every time. Please HELP!!! regards

  • Help setting up NSD daemon (DNS server)

    - by Catalin
    While searching for a secure dns server I came across the NSD project. I was really impressed by what seemed to me the best option out there that's open source. One problem thought their 'tutorial' is really not beginner friendly. I have basic DNS knoledge but what's in there is out of my league. I need to have multiple sites on this CentOS server I've recently got my hands on. They also need to receive email. Details: I have a master host and would love to set this in the way described in the rows that follow: masterhost.com -> ns1.masterhost.com mail.masterhost.com www.masterhost.com addonhost.com -> ns1.masterhost.com mail.masterhost.com www.addonhost.com And so on. Any help in setting up this DNS server please? All answers and suggestions are welcomed. Thank you in advance.

  • mysqlbinlog: unknown option '--ssl'

    - by Stefan Lasiewski
    I am running FreeBSD 7. running MySQL 5.1.36 from ports. I am trying to check some data in the MySQL binary log files, and I get the following error: # mysqlbinlog mysql-bin.000021 mysqlbinlog: unknown option '--ssl' In addition, I can't even view the help for this command: # mysqlbinlog --help mysqlbinlog: unknown option '--ssl' Why does mysqlbinlog not know about the option ssl? This server was compiled with SSL, and ssl is activated in the my.cnf configuration file. We use SSL for remote connections, but I am running this command on the local host.

  • NLB 2 Windows Server 2003 Servers

    - by Paul Hinett
    I need to configure windows NLB on 2 dedicated servers I have. My main machine has been running for some time, with several domain names pointing to the servers primary IP address. Both servers have 2 NIC's installed, and both have several secondary public IP addresses available if needed? What IP address would I use for the cluster IP, does this IP need to be added to the IP list of both public NIC's ip address list? What IP addresses do I use for the host's dedicated IP? Please help, this is driving me nuts...i've taken down the server twice on accident today! Thank you in advance!
