  • Xfce gets really confused about session saving, etc

    - by Pointy
    I'm getting a new laptop running with 11.04 Ubuntu. I've got the xfce4 packages all installed, which is something I've had no problems with on any of my other machines. On this new laptop, however, though I can log in and use an xfce session without any problems, logging out of a session is problematic: I click the "Log out" widget from the panel and then "Log out" from its option dialog. Then the thing just sits there, not logging out. Subsequent attempts to open the "Log out" widget fail with an error about the session manager being busy. After maybe a minute or so, it logs out. Though I've got the "Save session" option checked in the log out dialog, xfce just makes a complete hash of the business. It does remember the applications that I had running, but it seems to forget about the window manager (!!) and the workspace configuration. I don't log in/out that often, and generally I don't care much about restarting applications, but the window manager being missing is of course pretty annoying. I like xfce because it's simple and unobtrusive and usually works pretty well. I've never experienced this, and I've got two other machines also running 11.04 with pretty much the same setup (straight Ubuntu install with xfce4 packages added). Is there some good way to diagnose stuff like that? edit — well I nuked my session cache, did an explicit save from the session widget, and now it works. Well, it doesn't save the workspace location for each client and instead opens them all up on the first workspace, but I think that may be because, in the session, xfwm4 is the last thing in the "Client" list, so before it's started all the other clients just pile up in the first (and only) workspace. I'm still curious about how exactly it gets so messed up. I certainly wasn't knowingly attempting anything fancy or unorthodox, though I may have done something fishy inadvertently.

  • Having trouble installing guest additions for a Xubuntu 13.10 guest OS in Virtualbox 4.2.10

    - by Duval Pearson III
    I am using Ubuntu 13.04 64-BIT as my host operating system running Virtual Box 4.2.10. I get this message when I tell virtualbox to install guest additions(CTRL+D),mounting the volume in the guest OS and run the VBoxLinuxAdditions.run file using root by: sudo ./VBoxLinuxAdditions.run It starts and then comes to these error messages: Verifying archive integrity... All good. Uncompressing VirtualBox 4.2.10 Guest Additions for Linux.......... VirtualBox Guest Additions installer Removing existing VirtualBox non-DKMS kernel modules ...done. Building the VirtualBox Guest Additions kernel modules The headers for the current running kernel were not found. If the following module compilation fails then this could be the reason.

It still says the kernel modules are missing and the window is not seamless. Any idea what could be the problem?

  • HD movies stutter.

    - by Absolute0
    I just put together a new system build in the hopes that all of my daily tasks would run smoothly and without any hiccups. Unfortunately I am still seeing some sound and sometimes video stuttering when playing HD movies in VLC (no problems with xvid/divx files). My setup is as follows: Intel core i5 750 quad core 2.66mhz 4GB ram asus p55 motherboard radeon hd 5570 video card 650gb 7200rpm western digital sata HDD 23" Nec ea23wmi monitor Operating System: Windows 7 What might be the main bottleneck that needs upgrading to fix my delays? Seems like the hard drive might be the problem but anything faster than 7200rpm is beyond my budget for a decent hard drive. Could it be anything else?

  • Windows 7 and XP Networking

    - by David-Zazeski
    I'm trying to setup a home network between a windows 7 and windows xp machine. I have a small hub. My XP computer has a manually assigned IP address (192.168.0.10) and I set my Windows 7 machine to have a manually assigned IP address (192.168.0.15). The XP computer works, but the Windows 7 machine does not see the network. It says that there is no connectivity. Ping does not work from either machine. Does anyone have any suggestions?

  • Using 2 Transparent HAProxy for load balancing

    - by Nyxynyx
    We can configure HAProxy to be a transparent proxy by using the guide here, where one of the steps says ...to put the backend servers in a different subnet to the front end clients and make sure that the default gateway points back at the HAProxy load balancer. However when we need to have 2 transparent HAProxy in front of our balanced servers (for redundancy), it seems like this wont work as we can only set one gateway for our balanced servers. What will be the correct way to setup the system such that we can have 2 transparent HAProxy infront of the balanced servers? The main reason for having transparent proxies is the need to find the client's IP addresses over TCP.

  • Load balance between two virtual directories on a single machine running IIS6

    - by Emil Lerch
    I'm trying to simulate a production environment using a single VM. The production environment will have 3 servers behind a load balancer with sticky sessions. Production will be using IIS6. For development, I have no need to distribute load, but I want to make sure the team does not write code that relies on a single-server module. I have been hoping to set up two virtual directories and find some isapi filter to perform some rudimentary software load balancing, but I've been unable to locate anything suitable. isapi_rewrite comes close but there's no ability for a random rewrite. I don't even need sticky sessions since the application does not (in theory) rely on them. Is there something easy/free to do this, or am I stuck with multiple VMs and a NLB setup (which seems like total overkill)?

  • Configure Nginx On Separate Server For Zimbra Webmail

    - by alphadogg
    How do I properly configure a server with nginx to front for a Zimbra server with multiple domains? I run a small SOHO network. I NAT/port forwarding on my Comcast router to get traffic to my handful of servers. I setup a server with Zimbra, call it host1.internal.local. The server currently has two domains, call them domain1.com and domain2.com. Both offer webmail access at webmail.domain1.com and webmail.domain2.com. I have a separate server with nginx. I want to configure nginx to reverse proxy, such that I can direct all HTTP/HTTPS, and send webmail traffic via matched host address/headers to the Zimbra server. If possible, I'd like to know how to map IMAP, POP and SMTP traffic too. How would I do this?

  • How do I do a swing migration of Exchange 2007?

    - by Graeme Donaldson
    As per my previous question, I have an Exchange 2007 box which is also a DC. Since I can demote it while Exchange is installed, I need to a swing migration. Does anyone have any articles, tips or experiences to share on this? The last time I did a swing it was with Exchange 2003 and even that is a little rusty in my head. The setup is a single Exchange 2007 Hub/Edge/Mailbox/CAS server. Its currently on Windows Server 2008, I can migrate it to the same OS, or I can go to 2008 R2, I'm not really picky on that. We're running OWA/ActiveSync/POP3(S)/IMAP(S) for client access. I already have another fully functional DC/GC/DNS box in the same site and clients in the site are already using that for DNS. It's also the preferred site bridgehead for AD replication. Any tips?

  • Dell SC1435 always requires F1 at boot

    - by David Mackintosh
    I have a Dell PowerEdge SC1435 that has come back after doing duty at a partner site. I am trying to configure it for local use. The only problem I have with it is that every time it boots it always requres a manual F1 press after the POST sequence. The last thing it does is give me the opportunity to configure the BMC, and then it says: Press F1 to continue or press F2 for Setup It will wait there forever (well, at least an hour). Pressing F1 starts the OS booting. I can't see the setting in the BIOS which controls this and I can't find it in the documentation. What am I missing?

  • php mail not arrives at gmail, not at local server

    - by thomas
    The php mail function I am using does not work completely. It will sent mails to gmail easy enough. However, emails routed directly to my internally hosted exchange server are not getting through. The servers/domains are setup is as follows. URLs are registered with Network solutions (www.independentsservice.com & www.isco.net) NS directs all traffic to our ISP (Socket.net). Socket directs as follows: Mail to our local server FTP to our local server HTTP to our website hosted on Chihost.com Traffic to our local server goes through a Watchguard firewall which routes mail traffic to our locally hosted Exchange server. Is there some reason why exchange won't accept these emails? Thanks!

  • Problems installing LYNC on non-domain controler

    - by Trikks
    I have two servers in this set up. AD and EX, the domain is called mydomain.net The AD is a Windows 2008 Server (32 bit) with Active Directory installed AD only has it's own ip in the DNS-servers list AD.mydomain.net does resolve correctly in the dns EX is a Windows 2008 R2 that is connected to the mydomain.net-domain EX only DNS server is the ip of the ad.mydomain.net There are no firewalls running between the two servers When trying to install Lync 2010 on the EX server I get the following error "Not available :Failure occurred attempting to check the schema state.Please ensure Active Directory is reachable." I can control the AD from EX, also login to it and do successful checks like netdom query /domain:mydomain.net fsmo ...that resolves correctly I suspect there is something fundamentally wrong with my setup, maybe Lync need a 2k8 R2 ad?

  • MySQL replication ignore data changes but not table structure changes

    - by Ed Manet
    Is there a way to setup MySQL replication so that CREATE TABLE and ALTER TABLE statements get replicated but INSERT, DELETE and UPDATE statements do not? I've got replication working fine and have several tables that are ignored as per the requirements. But we have a requirement that the slaves have an empty copy of the ignored table. We create those empty copies before we start replicating. Since the table is ignored, table structure changes don't get passed down from the master to the slave's empty copy. I know it's a strange requirement.

  • Ubuntu not shutting down ( going to black screen ) 12.04

    - by Orrin Fox
    I am currently using a USB persistent install of ubuntu. its a simple 4GB drive with a 2.8GB partition ( casper-rw storage partition ). I setup an administrator account and set it to login automatically. I also removed ubiquity to simply use this as a go anywhere install. Heres my issue. Im logged in as my account, and I click the top right gear and select "shut down". Text pops up showing its quitting processes.. etc. and then goes to the plymouth animation. But... The screen goes black, and then it goes to the login screen. Now when im at the login screen i go into terminal ( alt+F2 ) and dont you know, im logged in as Ubuntu. so then I try the following: ubuntu@ubuntu:~$ sudo shutdown now It goes to the plymouth screen again as if its shutting down, AND the screen goes black once again but the computer has not turned off, as in the usb is still flashing the light, the fans are still on, the only thing off is the screen. Is this a bug? If not maybe i did something wrong? Perhaps its that I made an account but... if there is a work around for this please let me know. Thanks again, Fox

  • Connecting to a secure, graphical, x session using a stateless thin client

    - by npeterson
    I'm looking for an open source, non-proprietery solution to this problem, any help would be appreciated. I'd like to setup a server running Ubuntu Server. I'd then like to connect to this server from a stateless thin client and use an x-session. This would occur mostly over local area networks, but also possibly over the internet. What would be the ideal set of software to accomplish this from a security, and usability standpoint? Are there any ready-made stateless thin clients that don't require proprietery software?

  • Problems getting Squirrelmail and passenger working on apache

    - by Kenneth
    I'm trying to have a setup where I want to run a squirrelmail and Passenger on the same apache server, having a url point to squirrelmail and everything else handled by passenger. I've gotten so far that both squirrelmail and passenger will run fine by themselves but when passenger is running it handles all urls. So far I've tried using Alias and Redirect to point a webmail/ url to squirrelmails directory but that does not work. Here is my httpd.conf file: <VirtualHost *:80> ServerName not.my.real.server.name DocumentRoot /var/www/sinatra/public # Does not work: #Redirect webmail/ /usr/share/squirrelmail/ #<Directory /usr/share/squirrelmail> # Require all granted #</Directory> <Directory /var/www/sinatra/public> Order allow,deny Allow from all </Directory> </VirtualHost>

  • Linux and ClickPads

    - by John
    I just got my Arch / Windows 7 dual-boot setup running... except for one thing. I have an HP dv6-3127dx laptop, which is an issue when it comes to Linux because it does not have a traditional touchpad, but a "ClickPad." This means where the left and right buttons exist, it is also sensitive to moving the pointer. The issue comes in when I try to steady the mouse with one finger, while clicking the left click with another, because the mouse freaks out. It's also an issue because it's not recognizing the right click whatsoever. I am currently using the default Synaptics drivers downloaded from pacman on Arch Linux, running Linux v2.6.36. EDIT: The question of course is, how can I fix this?

  • nginx dynamic servername with regular expression doesn't work for co.uk

    - by redn0x
    I'm trying to setup a nginx server which dynamically loads content from a folder for a domain. To do this I'm using regular expressions in the server name like so: server_name ((?<subdomain>.+)\.)?(?<domain>.+)\.(?<tld>.*); This will create a 3 variables for nginx to use later on, for example when using the following url: test.foo.example.com this will evaluate to: $subdomain = test.foo $domain = example $tld = com The problem arises when the co.uk top-level domain is used. In this case when using the url test.foo.example.co.ukit will evaluate to: $subdomain = test.foo.cedira $domain = co $tld = uk How can I edit the regular expression so that it will also work for co.uk?

  • Advantages / disadvantages of having DynDNS access on a computer vs the router

    - by Margaret
    I have a shiny new toy, a Cisco Wireless-N Gigabit Security Router with VPN (WRVS4400N). While looking through the instruction manual, I discovered that it had support for DynDNS built-in. We've currently got the DynDNS client running on one of the servers (that people SSH to, as documented in this question); but the reason for the router update is to move away from SSH to VPN. To that end, is there any difference in behaviour/functionality/maintainability to run it off the computer, as opposed to the router? Thus far, DynDNS has more or less a set-and-forget setup, but since the feature was there, I wanted to know if it was a better location for the process...

  • Are mobo raid controllers based on Intel ICH10R southbridge still considered software Raid?

    - by Breadtruck
    So do you still need specific software/drivers (intel matrix?) installed to manage the raid controller, setup the array. If the raid chipset is on-board the motherboard and it uses the CPU, and say I am using a Core 2 Quad Q9550, would a hardware based card still out perform the motherboard chipset? This is for a home workstation and I could spend $300 on a areca ARC-1210 PCI-Express x8 SATA II but I want to be able to justify the money for the raid card. My motherboard is a GIGABYTE GA-EP45-UD3P UPDATE: I was going to RAID5 using 4 500 GB drives, and I was going to buy a controller card but this article got me thinking hmmm....Toms-Southbridge Battle

I've tried to add a new connection but the system can't see my device in setup dialogue. Also I have noticed that when I open eg. terminal and try to type sth, the system freezes for a while..

  • PHP not working when accessed through a domain name, but works fine when accessed through IP

    - by Allister
    Done a basic setup of Ubuntu Server installing Apache, PHP and mysql through tasksel. When I browse to the IP address of the server it works fine and allows me to render PHP scripts fine. So I added a DNS entry for the server onto my local DNS server, calling it webdev.lazer.net When I go to this domain name through my browser it renders HTML documents fine but if I try to view PHP scripts it doesn't render and downloads in plain text to the browser (As if the PHP parser isn't rendering .php documents). I'm sure its some rookie mistake, but any help would be appreciated. Thanks

  • How do internal smtp servers send mail to internal mail servers on the network?

    - by dmr83457
    We have upgraded our internal corporate email server and the IP address has changed internal to our network. A second email server is used for sending bulk jobs for a mailing list service that we offer. Since the switch of the internal corporate server IP we have been seeing problems when the bulk email server is trying to send email to our own domain. The log shows that it is still trying to hit the old corporate server instead of the new one. I have looked through all settings for the bulk email software and see nothing set there to send to internal mail servers, and I do not recall doing anything special to get this working when setup a couple years ago. Is there a setting in Win2003 or on the network that enables the mapping of MX record external IPs to internal IPs so mail gets routed correctly?
