What kind of specs are typical for a FC7 server hosting a PHP/MySQL application to 50-100 users peak? Can I get away with a VPS?

This is kind of a stupid question, I guess after all this time on Ubuntu I'm used to Windows and its "install something then it will work" approach. I recently installed Code::Blocks. I can write stuff fine, but I can't find a compile option. The only section in the compiler settings window is the "Batch builds" section. I tried making a project, but that window seems to not work - there's nothing to interact with really, and the OK button remains greyed out. I installed WXWidgets and the IDE's latest stable. I know I can compile fine since I can (and have been) compiling from the command line, and previous to trying Code::Blocks I was using Geany.

JawnV6 posted:My hard drive is dying. I have another of the exact same size already in the system, completely unused (I'm stupid like that). The biggest files on there are a 10G VM image and a bunch of dvd images that i don't feel like reripping. Yeah, that'll work fine - I've done that a few times in order to replace disks. The livecd is the best way to do it, but at a pinch you can just boot off the existing disk and drop to single-user mode. Mount up your source and destination filesystems (in these examples, /path/to/source/ and /path/to/destination) - if you've got /usr/ or /home/ or any other filesystems split off, make sure you've got them mounted inside the source directory structure. To do the copy, run 'rsync -av --progress /path/to/source/ /path/to/destination/'. Finally, you need to install grub to the destination disk. To do this, you'll need to - * Run 'chroot /path/to/destination/' * If /boot/grub/device.map exists, delete it * Run 'sudo grub --device-map=/boot/grub/device.map' * Type 'quit' to exit the grub shell - we only wanted it to recreate the device.map file * Look at the new /boot/grub/device.map and find the grub name (hdX) for the drive you've copied your files to. * Run 'sudo grub'. At the grub prompt, run - (replace hdX with what you found in device.map) - root (hdX,0) - setup (hdX) - quit * Type exit to get out of the chroot * In theory, you should now be able to pull out the old disk and boot off the new one. Make sure everything is working properly before you nuke the old disk

I've gotten the LiveCD to boot (after stupid pains), and just installed 8.04 onto the blank drive. Now when I let Ubuntu take a shot at mounting the drive, it either shows me just a few files or fails to mount entirely. I can't get it to show most of the files again like it did. I'm screwed, right? There's no "Like, really mount it now, k?" command line magic?

Only if both drives had the same geometry - you can get a (for instance) 750gig disk from two different manufacturers, and the capacities will be slightly different. Or the cylinders/heads/sectors values will be different, which will change the partition tables. In any case, unless the disks are 100% used, using rsync or cp will need to do less disk access.

Can anyone recommend me a decent VirtualHosting package for managing multiple sites on a web-host? Over the last few years my company started hosting web-based apps in-house and as business increased, so too did our needs. Now we're running dual redundant web servers, dual db servers and some test boxes. We're bringing on a new client that's pretty heavy and i'm going to be upgrading our whole rig. I'd like to move away from hardcoding vhosts in apache and move to something like Plesk or cPanel, but i don't know much about the market in those products. Are there any decent open-source applications that do this kind of thing, and if so, which ones should i look at? Note: All administration of these boxes is done by us, so while the ability to configure resellers etc would be a plus, it's definitely not needed.

I just installed Ubuntu 8.04 to get a feel for how it has cone along in the past couple of years. I installed the restricted NVidia driver and used nvidia-settings to configure my dual monitor configuration using TwinView. I was amazed with how easy this all was. I never even had to touch xorg.conf. The only problem is that new windows pop up in the middle of the entire desktop span, leaving them straddling the border between monitors. It gets pretty annoying when every dialog box is split between the two monitors. Is there any way to get things to center themselves on the primary monitor? Edit: Most programs seem to at least properly remember their last-used window positions, but smaller dialog boxes apparently don't do this and continually center themselves across both screens, regardless of the fact that last time I moved that particular dialog box.

Sounds like you need xinerama support in your applications. It's an Xorg option that programs have to support, but it gives them information on desktop properties, such as borders, so windows will "full screen" properly and spawn at the correct point for the "center". You still get goofy stuff with Java applications and other frameworks that don't give a crap, but for the most part it works well. I'm not sure how to install/enable xinerama in packages in Ubuntu, though. Chances are it will involve tweaking xorg.conf (You will never escape!), unless there's an Ubuntu widget for doing it automatically.

NVidia's driver contains its own Xinerama extension, so I believe this shouldn't be an issue. Thanks to you both for the help. I managed to fix it by explicitly turning on TwinView in xorg.conf. I guess turning it on in nvidia-settings is slightly less than perfect. But now everything is centered on my primary monitor, just like it should be.

taken from the ubuntu thread Aahhh poo poo! I tried my hand in partitioning and hosed it the gently caress up. I need help...  unallocated is where the old Mint partition used to be. extended, ext3 and linux-swap should be what Hardy is. I wanted to get the extra 44 gigs to use with the Hardy install and erased the Mint partition and set the boot flag with ext3 which is Hardy. But when grub boots I get "Error 17" and won't boot period. I'm using a Live session with the poo poo rt drivers. My sessions have been freezing up when I try and download a large sum of packages and I can "hear" the pinging up to a climax until everything freezes and it's silent again. I think I can try downloading one app at a time but all I really have to work with is gparted or other small programs. I need help. I miss Hardy. I'm so sad. /media/disk is what gparted mounts when I load it up, so all my stuff seems to be intact.

I think that you can just expand your Hardy partition to the beginning of the drive. I think thats why it can't boot, boot managers like to be on the first x sectors of the drive. Yours isn't anymore. See if you can just expand your Hardy partition to fill the remaining space.

sund posted:When you first turn it on, it won't take effect until you restart your xorg session, which is maybe what caused the problem. Running nvidia-settings with normal user permissions apparently won't get TwinView to stick permanently between X sessions. When I would restart X it would go back to only using my primary monitor. Adding TwinView options to xorg.conf seems to be a crucial step, so I guess that's why the "Save to X Configuration File" button is there.

Can someone point me in the right direction to get the restricted ATI drivers working in Ubuntu Hardy? Gutsy worked perfectly without any extra bullshit. I try installing the drivers, though, and when I enable them all I boot up to is a black screen until I run recovery mode and use xfix. I removed them completely, and then tried installing with EnvyNG and it gives me the same thing. I'm curious if I'm loving up somewhere, or if the 8.3 driver in the repositories is broke or something. I haven't tried the 8.4 driver directly from ATI.

Could you somehow give us the log file that is called /var/log/Xorg.0.log (or, if you're using X in that "broken mode", I think it's called /var/log/Xorg.0.log-old or something similar). It'll contain lines that point out where things went wrong.

It's rather big to copy paste, and I don't have any hosting http://www.megaupload.com/?d=WVCJKSVU On a side note - should just installing xorg-driver-fglrx and not even doing anything gently caress my computer up? I was just messing around, 'apt-get install'-ed it, then when I had to restart my session due to nautilus being rear end, didn't touch any config files or do anything other than installing, and I got the black screen. The GDM still appeared fine though, so I went into gnome failsafe, un installed the package, and it was fine again.

Ok, then -- since GDM comes up -- your X server seems to work, but perhaps you get crashing Gnome due to compiz and the desktop effects. Perhaps you could try the following: start in failsafe gnome or terminal, and enter the following command: "gnome-appearance-properties" -- once you're there, go to the effects tab (whatever it's called) and set it to "none". Then try to log in as usual.

rugbert posted:What kind of compression rate does tar have? using the -z switch gives you Gzip compression, and whatever rates go with that. Using the -j switch gives you Bzip2 compression, which is usually a bit better than Gzip. If you're backing up to tape and not using z or j, you're probably getting hardware compression, which is dependent on your tape drive. It's also dependent on what's being backed up. Text compresses significantly, jpegs and mp3's barely at all, since they're already compressed. Final thing to look at is what your script is doing. If it's running an incremental after a full, then your backup is only going to be a fraction of your full disk size.

Most Ubuntu stuff is set up to activate as soon as you install it.

This isn't really a linux specific question, but I figure this is probably the best place to ask. Are there any alternatives to Synergy? Needs to be cross platform (at least Win and Linux) like Synergy and have the same ability to let you use one keyboard/mouse between multiple systems with discrete monitors. I'm having all sorts of issues with the Synergy server (linux) randomly losing the connection to the client (XP). Sometimes I've got to restart Synergy on the client to get everything working again, sometimes I've got to restart the server. This has happened with two different Windows clients and with two different distributions (Ubuntu and Arch) on the server, and it's completely sporadic. Sometimes I can go days without any issues and others I've got to restart the client and/or server several times in one day. Any suggestions?

I've got a very simple iptables question. Here's the setup for our network: We've got about 10 computers in the house all going to a switch, and from that switch goes a cat5 to an ubuntu server with webmin in a guy's room that handles NAT firewall duties as well as DNS. Unfortunately our guy doesn't know how to forward ports in webmin. There are 5 of us in the house that regularly use Xbox live and it takes us ages to play a game of Halo and now we cannot play GTA online due to the "moderate" rating on our firewall. What's the command to forward all UDP port 88 and TCP/UDP 3074 packets to all devices in our network? Also, say my local address is 192.x.x.99 and I want to forward port 8080 from the outside to my PC, what would be the command for that? I've been trying to research it but I have zero experience with iptables, and the tutorials seem somewhat helpful but i want to make sure I'm not missing anything. Would it be something like this: -a INPUT -p tcp --dport 3074 -j ACCEPT ? Thanks a lot dudes Munkaboo fucked around with this message at 13:46 on Apr 30, 2008 |

Quod Libet has a powerful search function and a variety of interface modes. You also might want to check out a mpd based solution. You can have various programs access the server via command line to say set up your multimedia keys on your keyboard, or access the server over the network -- there's even web clients. It just takes a little longer to set up and the clients aren't as fully featured as some standalone music players. Another shot is foobar under wine. Wine is pretty awesome these days, and it can't hurt to give it a shot. Don't stop trying out various native applications if you go this route though.
