• CentOS running inside VMware as WebServer times out on outside connection

  - by Tom Hart

  I have a CentOS machine running inside VMware, and I have got PHP and Apache set up on it, so if I open a browser (on the VM) and go to either localhost, or 192.168.0.3, I get a phpinfo page I made in /var/www/html/index.php, but, if on the host (Windows 7), in my browser I go to 192.168.0.3, it times out. I can ping the IP address from Windows and get a response, I just can't through the browser. Does anyone have any ideas what I need to do to get this working? This is my first time using a VM and I'm getting lost in the network settings.

• Automatically save/download e-mail body to disk

  - by CatamountJack

  Is there a program that will allow me to connect to my mail server (IMAP) and automatically save certain new e-mails to disk? Multiple times a day I receive automated e-mail updates about pending jobs from a system that processes some information for us. The data in these e-mails is written as plain-text within the body of the message. I would like to download the newest message, parse it, and display it on my desktop. The last two parts I can manage ok - it's just the automatic downloading that is posing a challenge. I don't use Outlook (I do use Thunderbird), but would prefer not to have the client open to make this happen. I'm currently running Win7.

• Can I provision half a core as a virtual CPU?

  - by ramdaz

  I am virtualization newbie. Please advise on these questions. Please note using a commercial VM software like Citrix or VMware is not a choice for me. I have at my disposal a couple of 2x 4 core servers with 32 GB RAM. I need to create 16 VMs on each server to test some web applications. Can I provision half a core as a virtual CPU for each VM? To my best knowledge I can't do so on Xen. Is it possible on KVM or some other free open source VM solution? If it's not possible to assign half a core, how do I ensure that uniform processing power is available for all VMs? Since the job is to create separate instances for hosting 16 web apps in a physical server, do you recommend setting up a private cloud using Ubuntu Enterprise Cloud as a better option? Is there HA solution under KVM, like Remus for Xen?

• sftp to cygwin cmd fails with "received message too long"

  - by ana

  I have a windows server running cygwin, where open-ssh is set up. I am able to ssh into the server fine. I need to run a script that I cannot amend, and which needs to copy files via sftp, and requires the shell to be cmd. However, it fails with the message "received message too long" because when cmd starts it displays the Windows banner, and sftp chokes on this. I can't find any way to disable the banner, or redirect the output, or in any way get around this problem. Does anyone know how I can fix this?

  - by Chris S

  This is a Canonical Question about Fighting Spam. Also related: How to stop people from using my domain to send spam? There are so many techniques and so much to know about fighting SPAM. What widely used techniques and technologies are available to Administrator, Domain Owners, and End Users to help keep the junk out of our inboxes? We're looking for an answer that covers different tech from various angles. The accepted answer should include a variety of technologies (eg SPF/SenderID, DomainKeys/DKIM, Graylisting, DNS RBLs, Reputation Services, Filtering Software [SpamAssassin, etc]); best practices (eg mail on Port 25 should never be allowed to relay, Port 587 should be used; etc), terminology (eg, Open Relay, Backscatter, MSA/MTA/MUA, Spam/Ham), and possibly other techniques.

• How to move 100mb hidden system reserved partition on Windows Server 2008 R2 to other drive?

  - by Artyom Krivokrisenko

  Hello! I have a server with two 1.5TB hard drives. I was going to install a Windows Server 2008 R2 and create software RAID1 using Windows Disk Management Utility. I instaleld Windows, open this console and that is what I see: http://i.imgur.com/KoC9a.png Setup program created a System Reserved Partition at my second HDD. I don't understand now, how can I create RAID1, because space, which supposed to be used for copy of disk C, now is used for this hidden partition. So is there any way now to create correct RAID1? May it is possible to move this partition to the Disk 0, where I have plenty of free space? Unfortunately I can't reinstall Windows and apply other options at the disk management step of the installation, because installation image is not longer connected to the server and I have no physical access to server, only remote desktop.

• Fragile XenServer won't create new VDIs anymore

  - by thoiz_vd

  I'm getting increasingly frustrated with XenServer. Currently I'm using 5.6FP1 and it seems to be very fragile. Canceling any VDI-related action almost guarantees trouble. This time I tried to create a new VM using a snapshot for a template, with the fast disk cloning option disabled. It would take much longer than I was able and willing to keep my XenCenter open, so I canceled it. That took ages too, so I had to decide to "Quit Anyway." Since, I seem unable to create any new VDI. New attempts at cloning halt with "The attempt to clone the VDI failed," and creating new VMs based on built-in templates hang at "Provisioning." I'm in need of some advice how to solve this. What I did so far is run a xe vdi-list, which returned nothing odd to me, but I'm no expert. I assume that an incomplete VDI is blocking my Storage Repository somehow, however, how to deal with that remains unclear.

• Low-cost, Flexible Log Aggregation [closed]

  - by Dan McClain

  I'm starting to have quite the collection of Ubuntu VMs that I must manage. I'm starting to investigate Puppet for managing the configuration of all of them, and apticron to let me know what's out of date. But the issue I feel I should deal with sooner than later is log aggregation. I'd like to stay in the free/open source realm for now, seeing that we don't have much budget for something like splunk yet. In addition to syslog, I would like to collect application specific logs (We are running different apps on different machines, from nginx+passenger for rails, to Apache+Tomcat for java, to PHP for expression engine, and mysql/postgresql database server), so that we can analyze the relavent data. For now, I'm just looking to get all the logs one place.

• Mac OS X: network disabled because security breach

  - by fireeyedboy

  Dear all, I just recieved a message on my Mac OS X system telling me (loosely translated from Dutch): "The network has been temporarily disabled because the network's security was breached." (It's a wireless WPA2-PSK secured network BTW) I looked in the logs of my router (a Zyxel P-2602HW-D1A) only to see a few (outbound) "syn flood TCP ATTACK" logs, but those were from like a week ago, other than that nothing. What tools on Mac OS X do I have to analyse this security breach occurence? Are there some security logs on Mac OS X that I can inspect? What other measurements should I take? And how serious should I take this warning from Mac OS X? System: Macbook Pro Intel Core 2 Duo 2.2 Ghz OS: Mac OS X 10.5.8 Network: wireless WPA2-PSK Relevant software: Parallels Desktop with Windows XP (was open, but stopped at the time) Other systems on my network: Windows XP SP3 desktop (was running at the time) If you need any more info, don't hestitate to ask. Thanks in advance.

• Thunderbird message panes

  - by MarkS

  I have just switched from Outlook to Thunderbird and one feature that I am missing is when I would click a folder it would open a message in the message pane automatically. Now it is always blank. I have it set to remember the last one opened so if I switch back and forth it is there, but if I just click a folder the first time that I invoke it the message pane is blank. The reason I upgraded to 3.0 is because I saw this behavior in 2.0 and thought it would be fixed. I remember setting something in 2.0 that allowed this feature. Is there a way I can downgrade back to 2.0?

• Should a webserver in the DMZ be allowed to access MSSQL in the LAN?

  - by Allen

  This should be a very basic question and I tried to research it and couldn't find a solid answer. Say you have a web server in the DMZ and a MSSQL server in the LAN. IMO, and what I've always assumed to be correct, is that the web server in the DMZ should be able to access the MSSQL server in the LAN (maybe you'd have to open a port in the firewall, that'd be ok IMO). Our networking guys are now telling us that we can't have any access to the MSSQL server in the LAN from the DMZ. They say that anything in the DMZ should only be accessible FROM the LAN (and web), and that the DMZ should not have access TO the LAN, just as the web does not have access to the LAN. So my question is, who is right? Should the DMZ have access to/from the LAN? Or, should access to the LAN from the DMZ be strictly forbidden. All this assumes a typical DMZ configuration.

• Running evrouter at boot with init.d, or after xserver starts

  - by J V

  I'm using evrouter to set up mouse button binds, and init.d to start it. My init.d file: #!/bin/bash #Simple init.d script to run evrouter ### BEGIN INIT INFO # Provides: evrouter # Default-Start: 2 3 4 5 # Default-Stop: 0 1 6 # Short-Description: Set evrouter bindings # Description: Set evrouter bindings at boot time. ### END INIT INFO config="/opt/hacks/evrouterrc" case "$1" in start|restart|reload|force-reload) evrouter -c "$config" /dev/input/event* ;; stop) echo "Evrouter is not a daemon, change settings file at '$config' and restart" ;; *) echo "Usage: $0 start" >&2 exit 3 ;; esac evrouter however complains that: evrouter: could not open display "". If evrouter requires xserver to be up, how do I get init to wait until after xserver starts to run this script? If xserver restarts will this script run automatically? Running this with sudo services evrouter start still results in this error, can init.d scripts not tell where my display is? (Not exactly familiar with init, runlevels, etc)

• Use external speakers with laptop hooked to separate monitor?

  - by lhan16

  I have a laptop with a set of external speakers hooked up to it on my computer desk. The speakers use the standard 3.5mm audio (headphones) jack. The speakers work fine, but I've recently added a separate monitor to my laptop via HDMI. With the monitor hooked up to my laptop and the speakers still hooked up to the laptop, sound will only come out of the built-in monitor speakers. When I look at my audio settings, there are three different "audio playback devices" showing up, but only the built-in monitor speakers make noise when I click "test" (and I hear nothing when I set any of the other devices as the default. Does anyone know how I can still use my external speakers when using a separate monitor with my laptop? I'm hoping there is a solution that doesn't require the laptop to be open or closed, because I use both scenarios. I came across this post, but it doesn't look like they had much luck.

• Making evince the default application for embedding PDFs in firefox in ubuntu

  - by Seamus

  While I'm on the subject of complaining about things that upgrading to ubuntu 10.04 broke (see here), another problem that happened on moving from 9.04 to 9.10 (I think) is this: Firefox used to open embedded pdf files with evince and that was fine. Now it opens them with okular, which I don't like for several reasons. (Pg Up, Pg Dn keys don't work. I don't like the KDE save file dialogue box, because I'm used to gnome. ) So my question is: how do I change which program is used to embed PDFs in firefox in ubuntu?

• What ssh command would I use to set up "backwards listening"

  - by Nathan

  Machine A is behind a firewall. I have physical access to it, but I want to log into it remotely, and I do not have access to the firewall settings. Machine B is remote, and not behind any firewall. (It's my linode) Machine C is the mobile device I'm going to attempt to ssh into A from. Is there an ssh command that I can run from machine A that connects to machine B and stays open, that will allow me to log into A from C, via B? From the manual I'd guess it would be to run the follwing on A ssh -R *:9999:localhost:22 me@B and then run this on C ssh me@B -p 9999 but the previous command reports "Connection refused."

• Trying to mount NFS share on Windows Machien at startup with Z: letter for all users

  - by ScottC

  Windows Server 2008 We are trying to mount a specific drive letter on a windows machine from a unix machine. We need the mount to be available to the server even if no users are logged in and to users who are logged in with If we run the command from the command prompt manually it conencts and we have access to the NFS share, and can open it and see and edit files. mount -o fileaccess=777 anon \\127.0.0.1\nav z: (ip address replaced with 127.0.0.1 for security reasons) However if we try to automate the task by making an entry in the task schedule for boot time, to execute the batch script, it adds a disconencted drive to the list in 'My Computer' but it is disconencted and when trying to access the drive an error is produced: Z: is not accessible The data area passed to a system call is too small.| Tried as administrator with highest privelidges, as SYSTEM (group) and as my user (adminstator level user) same results. Is there another way to do this? Most of the help I have found online suggest this way but it keeps failing.

• OSX: Selecting default application for all unknown and different file types (extensions)

  - by Leo

  I work in cluster computing and am using Mac OS X 10.6. I send off hundreds of computing jobs a day, and each one comes back with with a different extension. For example, svmGeneSelect.o12345 which is the std output of my svmGeneSelect job which is job number 12345. I don't control the extensions. All files are plain text. I want OSX to open any file extension that it hasn't seen before with my favorite text editor when I click on it. Or even better set up file association defaults for extension patterns ie textEdit for extensions matching *.o*. I do NOT want to create file associations for individual files since this extension will only ever exist once, and I do not want to go through the process of selecting the application to use for each file. Thanks for any help you can offer.

• Postfix: how to use simple file for SASL authentication?

  - by Jonathan

  I'd like to run Postfix on a Debian VPS to send e-mails from my application. The application (running on other VPSes) would connect to Postfix via SMTP. Postfix does not have to handle incoming email; it's just about sending the outgoing messages. To prevent being an open relay, SASL authentication should be used. However, I don't want to run Dovecot or MySQL for SASL authentication. How can I setup SASL authentication using a simple file (containing usernames and passwords)? I already found a similar question; however, no satisfying answers where given there.

• Locking down a box on the web

  - by glowcoder

  I'm a Java developer who is looking to put a game on the web. I'm not much of a web or server guy, though, and frankly I seem a little lost at where I should start with putting something on the web. My application works fine on my machine, and I'm sure I can make it work fine on any box I put it on. But the security of that box is pretty important. If I sign up for a standard hosting package (let's say from GoDaddy or something) can I simply tell them "make port 12345 open for communication" and let them handle the rest of the security details? If I can't, what are the things I'm going to need to know to prevent my game server from getting hacked to shreds? (Links to solid resources fine by me!) Thanks!

• IE8 Crash On Startup

  - by Wonko the Sane

  Hello All, I have a problem - IE8 has suddenly stopped working. I was doing some development work, and suddenly IE8 crashed every time I tried to use it. I've rebooted, but still crash every time I try to open it. There is no real indication as to what has gone wrong. It just says "Internet Explorer has stopped working". I've tried almost everything that I've seen when I've Googled it: I disabled all Add-Ins via Manage Add-Ins, but it still crashes on startup* I re-registered IEPROXY.DLL * The thing I don't understand is that if I start from the Run box with the -extoff option, IE starts up. Isn't that the same as disabling all Add-Ins? Any ideas? Thanks, wTs

My ISP provides dynamic IP's with me connecting via pppoe. My question is how do I configure openwrt to work with this. Please suggest what option should I go with, or any other you recommend. DSL cable--Beetel Modem-- Wrt54gl in bridge mode with beetel modem doing the pppoe and having a DHCP server. DSL cable--Wrt54gl with wrt54gl handling the pppoe. Is option 2 possible, can I have a setup without bringing the beetel modem in the picture at all?
