  • Sendmail on ubuntu 12.04 64 bit connection times out?

    - by adam
    Okay i get the following error message: to=<[email protected]>, ctladdr=<www-data@adam-linux> (33/33), delay=2+08:20:35, xdelay=00:00:00, mailer=esmtp, pri=25590437, relay=adamziolkowski.com., dsn=4.0.0, stat=Deferred: Connection timed out with adamziolkowski.com. I'm guessing to make sendmail work. I have to change the default outgoing port number to 465 because comcast blocks port 25. Any ideas? What could be causing this error?

  • How to dynamically generate PDF documents

    - by Thomas
    I want to build a web application for generating stylish PDF documents. The layout should be based on a design templates and the data should come dynamically from the database. Ideally I want to design the template in a "publishing like" tool with placeholders and replace these placeholders by the web application with the data from the database. Think of something like an invoice generator, where a customer could choose from different invoice templates and the invoice data itself coming from the DB. Thanks for your ideas!

  • How can I make a webmail URL available from any hosted domain?

    - by James
    I run Roundcube webmail on my VPS. At the moment, it is only accessible from one virtual server hosted on the server, unless a separate Roundcube installation is created for other virtual servers. I would like to be able to make webmail available from any domain/ virtual server that I host, just by adding /webmail to the end. I'm sure Apache must allow me to do this - only problem is, I don't know how! Any ideas?

  • A way to store potentially infinite 2D map data?

    - by Blam
    I have a 2D platformer that currently can handle chunks with 100 by 100 tiles, with the chunk coordinates are stored as longs, so this is the only limit of maps (maxlong*maxlong). All entity positions etc etc are chunk relevant and so there is no limit there. The problem I'm having is how to store and access these chunks without having thousands of files. Any ideas for a preferably quick & low HD cost archive format that doesn't need to open everything at once?

  • Ubuntu 10.04 Cant Adjust brightness on my lenovo Thinkpad?

    - by Mo.
    I cant seem to be able to adjust the brightness on my think-pad laptop running Ubuntu 10.04. In the power management applet it shows that the power is set to 100%, but even if i try to lower it the actual screen brightness dosent change. Any ideas of how I can get around this? I tried changing the brightness from the terminal but its already set to Max brightness (however the actual screen brightness is no that bright at all). Thanks

  • How to configure an Ubuntu 12.04 virtual server and VMWare ESXi5 the way VMWare would be able to shut it down properly?

    - by Ivan
    I run an Ubuntu 12.04 server as a virtual machine on a VMWare ESXi 5 server. I've configured VMWare to shut the quest machines down the sane way (with an ACPI (if I understand it righ) shutdown signal so that guest OSes would do it). And this works with other VMs (running Windows 7 Professional and openSuSE) but doesn't work with the Ubuntu server - VMWare still offers just to power them off when I ask it to stop the guest. Any ideas how to fix this?

  • Unsafe shutdown on power button press (Ubuntu Server 13.10)

    - by Sam Bloomberg
    I have Ubuntu Server 13.10 set up on a machine, and whenever I press (not press and hold) the power button the machine doesn't safely shutdown (it instantly powers off), though it does flash the message "acpid: exiting" before turning off. If I instead run shutdown -h now, it goes through the usual cycle of stopping processes, unmounting filesystems, etc... Any ideas why this might be? I want the power button to safely shut down the system (unless I hold it down, of course).

  • How can I debug what's slowing down new session logins?

    - by David Planella
    For a while, I've had an issue whereby it takes up to 5 minutes from the moment I enter my password in Lightdm's login screen until I can do anything with my computer. That's on Ubuntu 12.04. During that time, I see there is disk activity, but I'm not sure how to figure out what's causing it and whether that is the real cause. I've played around with Bootchart unsuccessfully. Any ideas on what the best way to debug this issue is?

  • Menus intermittantly take two clicks

    - by heynnema
    Intermittently, when I left-click on the Applications/Places/System menus, the first click does nothing, and it takes a second click to drop the menu. I've also noticed that hiarchial menus sometimes don't show their expanded menus unless I move the mouse pointer away to another menu item, and then come back into the hiarchial menu. And lately, I've even noticed that in some applications, menus are acting the same way. Any ideas? Cheers, Al

  • Problem after upgrading to 13.10

    - by paul Barnett
    I am a new user to Ubuntu and not a very accomplished user. I have dual partitioned my laptop, recently upgraded to Windows 8.1 and also Ubuntu 13.10.Now when I boot into Ubuntu I get a running line of 3's and squiggles followed by scrolling (with a fail on the line "reload cups, upon starting avahi-daemon to make sure remote queues are populated"). If I press any key, but mostly return, it will boot into the password page. Any ideas? Thanks.

  • How to deal with checked exceptions that cannot ever be thrown

    - by ammoQ
    Example: foobar = new InputStreamReader(p.getInputStream(), "ISO-8859-1"); Since the encoding is hardcoded and correct, the constructor will never throw the UnsupportedEncodingException declared in the specification (unless the java implementation is broken, in which case I'm lost anyway). Anyway, Java forces me to deal with that exception anyway. Currently, it looks like that try { foobar = new InputStreamReader(p.getInputStream(), "ISO-8859-1"); } catch(UnsupportedEncodingException e) { /* won't ever happen */ } Any ideas how to make it better?

  • Attending my first software conference - any tips before I go? [closed]

    - by Paul Weber
    My nice employer allowed me to visit a software conference in June (International PHP Conference, for those who care). Wanting to make the most of it, I would ask the more experienced conference goers in here to give me some tips on what I could do to maximize my learning experience on the conference, and to reduce beginner mistakes. Sorry that this question is a little ambiguous, but I think it's best to keep it a little bit more open, so I can get a wide range of Ideas, and it will be of more use to further people seeking for an answer.

  • Can not add custom keyboard shortcut

    - by krasilich
    I'm trying to assign custom shortcut to lunch my own script (I don't need it in terminal window, just lunch it) So, I went to Settings - Keyboard - Shortcuts - Custom Shortcuts press the button with "+" and enter the name of shortcut and the command itself. But then I cannot bind keys to that shortcut. I select new row and press needed keys (Shift + F3) and nothing happens. I can change the keys for system shortcuts, but do not have any luck with my own. Any ideas?
