  • Redirect an Apache2 SSL VirtualHost with mod_alias

    - by Jeff
    I want to make sure there aren't any odd behaviors that I don't know about when redirecting a SSL VirtualHost with mod_alias Redirect as outlined by Apache here. My code seems to work, but since SSL virtual hosts are restricted to just one IP address, I want to make sure there aren't any problems eluding me. Explicitly not using TLS. I'm stuck with Apache 2.2 for now. <VirtualHost *:443> ServerName example.com SSLEngine On Redirect 301 / https://www.example.com/ </VirtualHost> <VirtualHost *:443> ServerName www.example.com SSLEngine On # Do stuff # </VirtualHost> So I guess my question is, should SSL VirtualHost redirection with mod_alias Redirect work the same as non-SSL redirection?

  • Tools to monitor guest OS performance in vSphere

    - by Quick Joe Smith
    I am looking for some tool or way to retrieve performance data from guest VMs running under vSphere 4.1. I am currently interested in the 4 basic metrics: CPU(%), Memory(%), Disk availability(%) & Network utilisation(Kb/s). The issue I have is that all of vSphere's performance data is from a ESXi host perspective (active, shared, consumed, overhead, swapped etc.) which is far removed from the data from the VM's own perspective. For instance, I have a Windows server VM idling, using around 410MB (~25% of its allocated 2GB) as reported by Task Manager, and this is the value I'm after. vSphere's metrics seem unable to arrive at this figure by any reliable and repeatable means. Is anyone aware of tools that can obtain this kind of data? The simpler, the better.

  • Ubuntu displaying GDM but no login

    - by Shawn
    Ubuntu (Wubi, Lucid Lynx) boots and shows the login screen itself with the background and plays the boot sound but a list of users is never displayed. A mouse is on screen and I can move it but, alas, it does nothing. Dropping to a virtual term with CTRL+Alt+F# drops me to a cursor but I can't actually input anything. I can't boot into single-user with GRUB since it's Wubi and it never specifies a boot kernel directly in GRUB's initial menu.lst (only in files that it then reads from). Other details that may be helpful: Single monitor Same video card that's been working for months No new hardware Edit: I ssh'd in since it evidently booted up the sshd which is handy. dpkg-reconfigure gdm didn't do anything helpful. I do, however, get a "no seat-id found" when manually running it.

  • rpd over https using a linux client

    - by Nils
    My employer switched from vpn and rdp to using what our admin calls "rdp over https". Since that switch I find myself unable to connect to the "new" rdp server. I think the progress is as follows: A rdp gateway-server is connected via tls the requested sever (different from the gateway-server) is then connected through the tls connection. In windows mstsc-settings the server name is the "internal network name" of the machine I wish to connect. And on the last tab (in German it is called "leistung" - could be activity) I go to the "connection from everywhere" settings and set the gateway-server under gateway-server. Now: Is there any way to use this scenario under linux (apart from a virtual machine running Windows)? I am interested in free ideas (e.g. is it possible to create a tls tunnel and connect through that using freerdp/rdesktop?) non-free ideas. As long as they work I'll worry about the costs later. Free ideas would be better :-)

  • Setup dhcpd without gateway on purpose

    - by MBober
    I have an XP machine with two network interfaces. One is connected to my company's network (and the Internet). The other is a very local network which connects some hardware with my PC. Both the hardware and my XP machine's second network interface obtain configuration from a dhcpd running on Ubuntu in a virtual machine on my XP machine. I entered some dummy gateway in /etc/dhcp3/dhcpd.conf like 192.168.3.1 which does not match any existing device just to get dhcpd started. The problem is that my XP machine now tries to route Internet traffic through 192.168.3.1 in most of the cases which, of course, results in an error. Is there any way to set up dhcpd in a way that the clients know that there is no gateway in this network? By the way: setting the gateway manually in XP is off the table because this needs administrator privileges which I don't have.

  • How do I make compiling code not bring my system to its knees?

    - by Jason Baker
    I have a macbook with snow leopard and 2 gigs of RAM. When I compile C or C++ code, my system becomes all but unusable. For instance, when I compile llvm I notice that there are about 10 or 11 processes (cc1plus) getting launched at a time that suck up my CPU time and memory. Is there any way to maybe make it compile less at one time? I'll gladly wait a while longer to have my system usable while I'm compiling. Or is this something that you just have to live with when compiling C or C++?

  • hardware addressing and configurable addressing scheme

    - by Zia ur Rahman
    basically i want to ask question about configurable addressing scheme for LAN interface hardware. i have read about it from a book, some main points are given by a configurable addressing scheme provides a mechanism that a customer can use to set a physical address.The mechanism can be manual (the switches that must be set when the interface is first installed).or an electronic memory such as an EPROM that can be downloded from the computer(what does this means). Most hardware needs to be configured only once- configuration is usually done when the hardware is first installed. Question:Suppose a network administrator configures the LAN interface hardware (assigns the address) when he installs it. Now later on if he needs to change the physical address of the device can he change it? Or in this addressing scheme the hardware can only be configured once and we can not reconfigure it later on.

  • File access with hostname or ip only - no domain?

    - by Jonathon
    It seems likely that this is an obvious question, but I'm having trouble tracking down any useful information. Normally when accessing files in a particular directory on a server, I'm able to create a virtual host, assign a domain, root directory location, etc -- however am in a situation where I have server space and need to access files with only a hostname. Is this possible? For example, let's say the hostname is 123hostname.com, and the file I want access to is in /home/sub-directory/filename.php. How do I get at it via a browser? I've tried: http://123hostname.com/home/sub-directory/filename.php ...and some other variations on that theme (that I can't post because new users are restricted to one link in messages). But generally stuck. Any help -- even if it's just to let me know that this isn't possible without some additional configuration -- would be great. Thank you!

  • MongoDB on FreeBSD

    - by Hartator
    We are currently using MongoDB 2.0.0 on MacOS but our servers are running FreeBSD. The most recent port of MongoDB is the 1.8.3 version. I have tried to compile the 2.0.0 by hand but I came across errors that I didn't manage to fix. I came across on the Internet a few old resources which are saying that MongoDB does not run well on FreeBSD mainly for performance issue (memory mapped files). Is that true ? Does it mean we have to switch our server to another OS ? Thanks for your opinions! Sources : http://groups.google.com/group/mongodb-user/browse_thread/thread/8131b7e5a5c710d9 http://ivoras.net/blog/tree/2009-11-05.a-short-time-with-mongodb.html

  • Is there any viable alternative to using a linux/unix/BSD firewall/router/vpn?

    - by ObligatoryMoniker
    I am trying to purchase something to replace our Vyatta router that is running in a virtual machine on Hyper V (having the whole network go down when the host has to reboot is not convenient and I am getting the sense that this configuration may not be stable). Most posts on this topic suggest using Linux/OpenBSD/FreeBSD/etc with some recommendations to use appliances from vendors for specific purposes like firewall and VPN. We are a windows shop and it has been a stretch for us to make use of Vyatta but since it was free and straightforward to use we decided to use it. Now we need something that is easier for our team to (re)deploy and manage. I would rather purchase something windows based or an appliance that can do all of the following things: DHCP server (reservations, specified gateway, dns, etc) Static Routes that route traffic across three interfaces Easily Reproducible (Powershell script, Puppet, Chef, etc) Intuitive interface (Decent web interface would be fine but I don't want them to have to go to CLI) Does any one have any recommendations on what I should be looking at that might meet our needs?

  • Are Plesk server backups useful?

    - by Michael T. Smith
    I'm working for a startup now, and I'm the programmer. Because of our small team size, I'm also handling the server management for now (until we get a dedicated server administrator.) I've never used Plesk before, and the server we're using (a Media Temple Dedicated Virtual server) had it installed when I got here. One of my first jobs was to set up backups: Plesk was already running it's nightly server-wide backups. I created a small script to dump the web app, it's DBs and any assets, tar them, store them, and then copy them to another small server we have (to backup the backups.) But, we're constantly running into hard drive space issues because of the Plesk backups. And I'm wondering, are they useful? If I have the web app and all of it's assets, I could easily enough get another server up and running. Do we need to keep running Plesk's backups? Thoughts?

  • DC on Hyper V Host

    - by Saif Khan
    I've read a few similar questions but wasn't clear. I have a small office (13) users and recently purchased a new single server (this is all I have to work with for now). Server specs Memory - 16GB Drives - 6 SCSI (2TB) PROCESSOR - DUAL QUAD I plan on making the Hyper-V host the DC and then 2 VMs, one for a file server and the other an application server. Question - since I am restricted to this single server, would it be a big issue making the Hyper-V host the domain controller? Your input greatly appreciated.

  • Shared FC LVM VG with LVs for each KVM VM. Clvm required?

    - by Cocoabean
    I have 2 virtual machine hosts running Ubuntu 12.04 and KVM managed with libvirt. They are both connected to the same VG which is a LUN on my SAN over FC. I provision LVs on this shared VG for each VM. I don't think I need HA or failover, but I do want live migration between the hosts. Do I need clvm in this case? As long as I don't try to start the same VM on each host should this work? Clvm requires lots of overhead with clustering tools that I don't think I need. I can deal with manually restarting VMs on other hosts in the event of a hardware failure.

  • virtualbox ftp hangs on list command

    - by Tiddo
    Hi all, I have virtual box installed on a windows 7 64-bit computer, with Cent OS 5.5 as guest os. I want to be able to use ftp between those. I've installed vsftpd on the guest os, and the guest os uses a nat connection with the host os for internet. So far, I am able to connect to the guest os using ftp (in filezilla), but after the list command is executed, nothing happens, until the command is timed out. This happens in both active and passive mode. I do have set a pasv_min/max_port in the vsftpd.conf file, listing is enabled, and the ports are redirected in virtualbox. Also the ftp_data_port is set to 20. I also tried setting the pasv_address, but I had to set it to 127.0.0.1, but than filezilla gives me this: Command: PASV Response: 500 OOPS: bad family Command: PORT 127,0,0,1,139,204 Response: 500 OOPS: child died Can someone help me with this?

  • ORA-01019 error only as an administrator

    - by Mike
    I'm having a strange problem. I've installed the Oracle 10g client on a terminal server running Windows Server 2008R2. When I try to connect to Oracle, using, say, Toad, I receive the error "ORA-01019 unable to allocate memory in the user side". But this only happens if I'm logged in as an administrator. If I connect as a normal user, I can connect without issue. Also -- if a normal user is connected, I can then connect without a problem as an administrator. Any thoughts?

  • How to make AD highly available for applications that use it as an LDAP service

    - by Beaming Mel-Bin
    Our situation We currently have many web applications that use LDAP for authentication. For this, we point the web application to one of our AD domain controllers using the LDAPS port (636). When we have to update the Domain Controller, this has caused us issues because one more web application could depend on any DC. What we want We would like to point our web applications to a cluster "virtual" IP. This cluster will consist of at least two servers (so that each cluster server could be rotated out and updated). The cluster servers would then proxy LDAPS connections to the DCs and be able to figure out which one is available. Questions For anyone that has had experience with this: What software did you use for the cluster? Any caveats? Or perhaps a completely different architecture to accomplish something similar?

  • MySQL on Windows - how do I set the wait_timeout for connections using named pipes?

    - by gustafc
    I use a MySQL database running on a Windows box, and for performance reasons I'm connecting to it using named pipes. The (Java) application using the database (through Hibernate) can let the connection lie idle for quite a long time, which causes the connection to fail with the following message: com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: The last packet successfully received from the server was 33 558 297 milliseconds ago. The last packet sent successfully to the server was 33 558 297 milliseconds ago. is longer than the server configured value of 'wait_timeout'. You should consider either expiring and/or testing connection validity before use in your application, increasing the server configured values for client timeouts, or using the Connector/J connection property 'autoReconnect=true' to avoid this problem. autoReconnect unfortunately has no effect (and neither does autoReconnectForPools), but the wait_timeout docs state that wait_timeout only applies "to TCP/IP and Unix socket file connections, not to connections made via named pipes, or shared memory". How can I change the wait_timeout for named pipes?

  • How can I restore Outlook 2007 from a PST file without having to import everything?

    - by schnapple
    I recently upgraded to Windows 7 and went the "format from scratch" route. I backed up my C:\ drive to the free space on my D:\ drive. So now I have Outlook 2007 reinstalled and I have my .pst files and so forth from the previous installation. If memory serves the answer on getting all those emails back into Outlook again is "create a new .pst file for the account and then reimport everything". What I'd like to do is be able to just put the .pst file where it's supposed to go and then have Outlook 2007 just "remember" everything. But I'm pretty sure this doesn't work. Is there a way to restore Outlook from a pst file without having to re-import everything?

  • Virtualhost setup, same IP address, different DirectoryIndex's

    - by kaykills
    I am trying to set up 2 virtual host entries in apache but I'm not sure how to accomplish what I want to do. I have two domain names, both pointing to the same IP Address. I need the DirectoryIndex to be different, which is pretty much the only difference in the entries. I have the following set up: <VirtualHost *:80> ServerName firstdomain.com ServerAdmin [email protected] DocumentRoot "/srv/www" DirectoryIndex /portals/site/index.html </VirtualHost> <VirtualHost *:80> ServerName seconddomain.com ServerAdmin [email protected] DocumentRoot "/srv/www" DirectoryIndex /portals/site/index_fr.html </VirtualHost> Not sure what I need to do differently but the second entry doesn't work. The only real difference is I need the second domain to point to a different DirectoryIndex. If there is a better way to accomplish this, your help would be appreciated.

  • Installing Software from a CD onto a Netbook

    - by Jonathan Sampson
    I apologize if this question has come up before - I can't seem to find it. Tonight my wife and I purchased a small samsung netbook and have been enjoying it for a light-weight solution around the house. My wife has a game she loves to play that was installed on her last laptop, but we'd like to put it on the netbook. The problem is, there's no cd-drive on the netbook and the game must be installed from a CD. What other ways can I install software from a CD onto the netbook lacking a local cd-drive on the device itself? I would prefer to not have to create image files, and mount virtual drives, etc.

  • Eclipse: would more CPU cores with HyperThreading help increase speed?

    - by Dylan
    I'm programming a very large project in Eclipse. Right now I use a dual core machine with 2GB RAM, but Eclipse is sometimes busy for minutes (refreshing/indexing/building), so I'm upgrading to a new machine (with 16GB RAM and an SSD). Now I must choose between an Intel 2500K or an Intel 2600K that has HyperThreading. The price difference is about $100. Would that be worth it, for Eclipse, or is more memory/faster drive much more important for Eclipse ? Can Eclipse make use of the HyperThreading at all?

  • Configuring Mail Relay

    - by ServerChecker
    I'm running Ubuntu Server 9.10 with Postfix and Webmin. I have created virtual hosts for 3 domains following this serverfault.com answer. But the mail isn't relaying out to the world. I have 3 domains tied into my DNS in webmin, as well as inside DNS clicked Mail Server and followed that instruction using this article on the web. The domains and the web servers work just fine. I also have FTP working just fine. So, the remaining problem I have is mail. Can't forward mail out to a Gmail account for some reason. Note I'm just trying to do the "easy version" of Postfix config and if your answer is in Webmin-ease, that would help me. However, I can edit a text file if you suggest.

  • Stream Music To Ventrilo From ESXi VM

    - by omghai2u
    I would like to stream music to my Ventrilo server from a Windows XP virtual machine running on an ESXi host. I have followed the instructions outlined here to stream music from something like VLC to the Ventrilo server on another machine and it works fine. I have also added the lines: sound.present = "TRUE" sound.virtualDev = "es1371" sound.fileName = "-1" sound.autodetect = "TRUE" to my .vmx file, as suggested here (http://communities.vmware.com/thread/191878), to get a sound card in my VM. The problem I am having is that it seems that my VM is not outputting any sound, so there's nothing to stream through Ventrilo. The Device Manager on the VM shows that this new sound card has drivers and doesn't appear to have any concerns with it. Can someone point me in the right direction to get my desired outcome? Thanks! PS. sorry for the long 2nd link, apparently I can only post 1 hyperlink with this low reputation.

  • Running a webserver behind a firewall I have no access to

    - by reijin
    I'm having a bad time in my student appartment: I want to run a webserver on my Laptop, which should be reachable from outside of the net. I'm sitting behind some proxy-server that passes outgoing packets to the matching server. But when it comes to incoming messages - it wouldn't route them correctly to my PC. (Seems like packets only get passed if some PC from within the student-flat is already connected to the sending server) In the past I had a small virtual private server that was sending incoming website-requests over a reverse shell to my PC. Which then returned the website content, and the visitor could see my website. Sadly I dont have that server anymore... Do you have any idea that might solve my problem? Greetings, Benedikt
