Ubuntu Servers :: Does Every Single Update Need Independent Reboot

Jun 17, 2010

My server keeps displaying a message: "The computer needs to restart to finish installing updates. Please save your work before continuing" every time I log on. Last night I did four consecutive reboots but the message is still there. I log i remote with NX / Gnome. Synpatic shows "0 to install/update 0 to remove".Is this normal? Does every single update need an independent reboot, so there is a queue to catch up with? Or is there some reboot flag that is not resetting properly after reboot?

Ubuntu Servers :: HOW TO Be In Two Places At Once A.k.a Ipredator Independent Of The Default Route

May 4, 2010

I have a home server running Lucid which basically runs our home lan, but I also wanted to be able to run transmission-daemon over an ipredator VPN connection completely independently of the ethernet port (as far as the application layer is concerned anyway). Most of the howtos for setting up VPN use the VPN as the default route, however I still wanted to run a webserver, dnsmasq etc, not to mention free bandwidth access to my ISP etc.

Thus, this howto. The ppp connection still tunnels through eth0, but as far everthing else is concerned my server has two independent network ports eth0 and ppp0 and applications use the default route via eth0 to our router unless explicitely directed down pppX. I assume that you already have transmission-daemon installed.

Ubuntu Servers :: How To Enable ContentDigest For Single Directory?

Apr 2, 2010

I have a folder just for download files (e.g., application update files). I would like to send the Content-MD5 http header for each file a user downloads.So, is there a way to send ContentDigest header for the contents of a specific directory only?The apache documentation makes it sound like I can set a context so that it applies to a directory only, but I can't figure out how this is done if this really is an option.Can anybody tell me if I am interpreting the documentation correctly and, if so, how to set apache to work this way?

Ubuntu Servers :: Allow Single Folder To Be Accessed Remotely?

Apr 18, 2010

I recently set up a computer running Ubuntu 9.10 Desktop for use as a server, and successfully have it hosting game servers.I'm relatively new to Ubuntu, so I'm not sure how to go about this, but ideally I would like a user to be able to access a single folder on the server over the internet, and be able to upload and download files from it.It would be nice to set up multiple folders like this, so different people would have access to their own personal folder, but not anyone else's.

Ubuntu Servers :: NFS - Exporting Multiple FS With Single Line?

Jul 26, 2011

I'm using my home server to netboot into live CDs. To summarize that article, netbooting a liveCD system involves passing an NFS host:/path in kernel's command line, which is subsequently mounted as /cdrom on the live system. The article mentions copying the contents of the iso image to a place on the hard drive, but I see no reason for this, since the contents need to be read-only anyway, which is easy to achieve by mounting the iso through a loop device:

Code:

# mount
...
/dev/loop0 on /mnt/kubuntu-lucid-amd64 type iso9660 (ro)
/dev/loop1 on /mnt/kubuntu-natty-amd64 type iso9660 (ro)

[code]....

Now, I am using NFS to mount a regular (rw, HDD) directory which I use as a network drive and I can mount any subdirectory and still access all the files within, ie. when I export /data on the server, I can still mount /data/downloads on the client:

Code:

server:# exportfs
/data 192.168.1.4/32
client:$ sudo mount -t nfs 192.168.1.1:/data/downloads /mnt/netshare

[code]....

Is it possible to export just /mnt and be able to mount any/all of the subdirectories? NFS doesn't like going across multiple file systems:

Code:

server:# ls -al /mnt/kubuntu-natty-i386/
total 3532
dr-xr-xr-x 11 root root 4096 2011-04-27 11:29 .
drwxr-xr-x 7 root root 4096 2011-07-25 21:46 ..

[code].....

When I try to export just /mnt and mount /mnt/kubuntu-natty-i386 on the client, the mount succeeds but the mounted directory is empty.

Ubuntu Servers :: Single User Mode Not Taking Password?

Ubuntu Servers :: Converting Single Disk LVM To RAID1 LVM (grub)

May 5, 2010

I have an Ubuntu Server on (8.10) running under Citrix XenServer (though that shouldn't make a difference).

I installed on a single disk:

xvda1 - 200 MB - /boot
xvda2 - 9.8 GB - LVM (ubuntu-base)

The LVM is:

swap - 1.0 GB
root - 8.8 GB - /

I have successfully gotten this converted to RAID1 by adding a new drive (xvdb) and following the Debian howtoforge article [URL]

What I have not been able to do, is get grub working properly.

If I fail xvdb and reboot the system, everything comes up and I can reboot and run.

If I fail xvda and reboot the system, XenServer gives me a bootloader error. i.e.: no grub

If someone has done this, can they tell me what grub commands to run to get a successful boot of the primary disk fails?

Ubuntu Servers :: Exim 4 Single Config File Location

Nov 16, 2010

I have a nice little interface that generates an exim config file and a script on the server to check for changes. Unfort I cant find where to set the config file location.

E.G. I have my script generate the file to /etc/exim/exim4.conf (could be /usr/share/foo/bar.conf just as easily)

How can I point exim in the direction of that file?

Ubuntu Servers :: Raid1 Reads At Single Disk Speed?

May 3, 2011

im on 10.10(desktop) and mdadm was v2.8.1 from 2008, very out of date so i tried 3.2.1 -> no change. mdadm raid1 read speeds are the same as single disk. note i used the tests in the disk utility benchmarking tool at first --these showed raid 5 atleast to be much better but when i tried dd reads raid5 dropped off with larger data to almost the same (slow) speed as raid1. compare:

[code]....

using two partitions will be enough to show raid1 performs at single disk speed. I dont really want to use a 4 disk raid0 just to get the read speed i should be able to get with raid1 as i dont really care about the size loss. I would of course use raid10 but i have found this suffers from the same problem (achieve same read speed as 2 disk stripe). So whilst im shocked others aren't reporting this, unless there is some obscure reason why my system would give these results i think raid1 in not behaving as it should.

Ubuntu Multimedia :: HOW TO MPD With PulseAudio Independent On X

Feb 7, 2010

This tutorial is meant for Ubuntu 9.10 Karmic Koala, but it might work in earlier or later versions as well. I wrote this tutorial mostly because it took me a full day of work using lots of help from people on #mpd and #pulseaudio from the FreeNode IRC server.The goal is to get the MPD daemon working using PulseAudio, but without it being dependent on the X server or a session. To do that we must configure PulseAudio to run in system-wide daemon mode (which is not recommended by the developers, but in this case we do not have a choice). This means it will be using the /etc/pulse/system.pa config file instead of the usual /etc/pulse/default.pa. We must also make sure the appropriate user/group permissions are set, or PulseAudio will be rejecting the connections.The result will be an interrupt-less music environment, not dependent on the X server. Meaning we can for example log out and log in without the music having to stop for even a second. Switching TTYs (Ctrl+Alt+Fx) will also keep the music playing (not possible by default). All that and PulseAudio will still be able to detect and configure all your devices automatically.

Instructions: Make sure you add your username to the following system groups: pulse, pulse-access and audio.Do that by going to System --> Administration --> Users and Groups.Click the unlock button (the one with a picture of some keys), then click Manage Groups. In the list of groups that pops up, for each of the previously mentioned groups click "Properties" and select all the users that you want to have this functionality.

Ubuntu :: Flash Drives Independent Of OS?

I'm buying a new memory stick online, but on the page I'm buying it from, it says "OS Required: Microsoft Windows XP, Apple MacOS X 10.1.2, Microsoft Windows Vista / 7" so I'm wondering does this mean it won't work in Linux (Ubuntu)? Because i thought that flash drives were independent of OS.

Ubuntu Servers :: Multiple Websites On Single Host Machine Without Virtualisation

Jun 1, 2010

I have this intra net server project going on and now I moved to 10.04 however there are still some things that I would like to see clarification and instructions on. I am interested to set up multiple parallel websites for my apache server, however I am not sure how to do this exactly. Now I have solid address rivera.wippies.net and port 80 redirecting to my server. What I would like to get done is that I get multiple independent of each other websites for my server I was thinking of making websites like this

/var/www/site1 (which would be as rivera.wippies.net)
/var/www/site2 (which would be as rivera.wippies.net/othersite)
/var/www/site3 (which would be rivera.wippies.net/secondothersite)

etc, so that I have multiple "individual" websties for my server. Requirements would be that each of these websites could have SSL encryption as needed available too, since some of the website could have confidential information.

Ubuntu Servers :: Inexpensive Single Board / Embedded System With SATA

I'm looking for doing AOE (Ata over ethernet) inexpensively with single board computers, like Routerboard stuff, but is there anything with sata plugs. Hopefully I can get each board for hopefully around $50, but a little more would be ok. Non-x86 is fine, Debian is as good as Ubuntu.

Ubuntu Servers :: Running Multiple Websites On Single Server - VirtualHost

Aug 25, 2010

I currently am running 10.04.1 and have successfully setup my home web server to run a single website. My current settings are:

-I have registered the domain name annarrankings.com through godaddy
-A record is - host = @ and points to = 71.114.220.3
-CName is - host = www and points to = @
-on my server I have the site running in /var/www

I've done some research and found that to run multiple websites I need to setup VirtualHost.

-So I created a folder /var/www/annarrankings.com and moved my site to that folder

-Edited Apache2.conf to add the following line

-I then went to /etc/apache2/sites-enabled and copied the default file to a new file called annarrankings.com. Here's the annarrankings.com file after I edited it

-I then created a link in /etc/apache2/sites-enabled to the annarrankings.com file in /etc/apache2/sites-available

-Next I editied /etc/hosts

-When i went to enable the site using a2ensite annarrankings.com I got the following

I figured this was ok since I had already created a symbolic link earlier (a result of trying to following multiple tutorials and ..... videos at once) so I reloaded apache2. I created an index.html file in /var/www/ just for testing purposes and when I load www.annarrankings.com I get the file located in /var/www/ instead of the website located in /var/www/annarrankings.com Do I need to change my A record or CName in godaddy or did I just do this completely wrong?

Ubuntu :: X Stopped Working After Massive Update And Reboot

Jan 24, 2011

I hadn't updated until yesturday night, today after the massive update and reboot, my x stopped working. What happens is, after the splash screen, both screens goes black and unresponsive. Tried killing X and alt + ctrl + f1 etc. I can probably fix this myself if I could access the terminal but, the other day I had to be stylish and remove everything from my grub boot besides Windows 7 and the default Ubuntu so I can't boot into root terminal. So, how would I gain access to a console before X starts?

Red Hat / Fedora :: Use Storage On Multiple Servers As A Single Cluster?

Apr 20, 2011

Can ANYONE point me in the right direction on how to use storage on multiple servers as a single cluster?I thought storage cluster was for that but, after much googling, and even more help from here, I don't think that achieves my goal. My goal is to have multiple servers share a file system, to act as somewhat of a network raid, so if node-A goes down the files are available on other nodes, and hopefully so when the capacity of the nodes are reached I can add nodes to expand the "cluster".

Software :: F14 Hangs On Reboot After Update?

Apr 16, 2011

fedora 14 did an automatic update and on reboot it hangs displaying the "f" before the login menu. The "f" is how I now feel......... I do "fn+f2" as it is booting and it displays the sequence of loading items which report all is "ok" until it gets to "jexec services" and then it hangs. I beleive the "jexec service" is a Sun Java item but I am not sure. I have been using Fedora successfully for a number of months and need to get data from the machine.

Ubuntu Installation :: Fetching From Update Servers Fail When When Using Update Managers?

Aug 21, 2010

I have Ubuntu Karmic 64-bit installed. Update manager tells me there are updates available, but when i try to install them, downloading the updates fail and throws this error:

Code:

Failed to fetch http://security.ubuntu.com/ubuntu/pool/main/e/eglibc/libc6-i386_2.10.1-0ubuntu16_amd64.deb

Consequently, a similar error occurs when I try installing Sun Java 6 Runtime.

Code:

Failed to fetch http://archive.ubuntu.com/ubuntu/pool/multiverse/s/sun-java6/sun-java6-jre_6-15-1_all.deb Connection failed [IP: 91.189.88.31 80]

Ubuntu Restricted Extras stalls when it's time to download the Java package I tried synaptic, update manager, aptitude, apt-get, and they all throw similar errors. Then I also tried connecting to different servers, to no avail. So to check if it's my connection to the net that has problems somehow, I tried downloading the file directly through my web browser, and it works. (But it's not recommended, and it won't let me!, install the updates manually, right?) I tried searching for the errors on the net and in the forums, and they're all somehow related to proxy servers. I then checked if I'm using some inappropriate proxy settings, and everywhere it's all set up to connect to the net directly, which is, well, my setup.

Take note though, that I am able to install other softwares normally, i.e, using synaptic, apt-get etc. The ones I tried include Pidgin and Mplayer. It's just these updates and Java:

Code:

jeanne@jeanne-desktop:~$ sudo sudo aptitude upgrade
W: The "upgrade" command is deprecated; use "safe-upgrade" instead.
Reading package lists... Done

Ubuntu Servers :: Every Time Logged In Via SSH Got A Message Telling There Where Packages To Update Including A Security Update?

Feb 11, 2011

I was running 10.04 LTS and had decided to stick to the LTS versions as I'm now running my machine as a server and don't want to be updating regularly.Every time I logged in via SSH I got a message telling me there where packages to update including a security update. So I did a search to find out how to perform an update on Ubuntu server from the command line.What I found was to do this:sudo apt-get updatesudo apt-get dist-upgradeAfter doing that I rebooted but now my machine gives me this message:

init: ureadahead-other main process (794) terminated with status 4Your disk drives are being checked for errors, this may take some timePress C to cancel all checks currently inprogressI'm not pressing C yet and leaving it alone to finish, but I noticed when the machine booted that one of the options for booting talked about Ubuntu 10.10, so I'm worried that I've updated from 10.04 LTS to 10.10 by accident?

Ubuntu Installation :: Grub Rescue Prompt On Reboot After Update

Aug 8, 2010

Installed 10.04 on my daughters laptop from within windows Vista. All went OK but I had two boot loaders, i.e. turn on laptop and I would get the Windows loader asking if I want to boot in to windows or Ubuntu. Upon selecting ubuntu I would get the standard grub loader that I have on my PC. Did an update a few mins ago and it asked me to update grub which I did and as there was only one disk showing clicked forward. Now on reboot I have grub rescue prompt, no such device. Hard drive is a single 80 gig drive with windows on one partition and ubuntu in another. Have the live cd so can boot from that I guess. What do I do next?

Ubuntu Networking :: 10.04 Kernel Update - No Ethernet Connection On Reboot

Sep 18, 2010

I updated to the latest available kernel for Kubuntu 10.04 today (2.6.32-24). When the system rebooted, it refused to connect to my wireless network. So far I have been unsuccessful in persuading it to connect. ifconfig shows the existence of the ethernet connection as eth0, and Network Manager also seems to accept the existence of the ethernet port - so why has it suddenly chosen now to stop connecting to the wired network?

Ubuntu :: Can't Open Terminal And Other Apps After Automatically Update And Reboot

Sep 24, 2010

I did an automatic update and rebooted this morning and I now have a bit of a nightmare situation where I can't open the majority of applications, including the terminal. When I rebooted, my desktop loaded as normal, but then when I try to open the terminal (from Applications -> Accessories or from my quick launch panel), nothing happens other than the quick launch panel disappears for a second then reappears. This is the case for most other apps, but not for Chrome (obviously).

EDIT: Used Alt+F2 to open the terminal, ran safe upgrade and then rebooted, but still having the same issue. As Ubuntu was booting, there was a "Broken pipe" message, which didn't stop the boot process but is still a bit worrying. I've run a file system check but this hasn't resolved the problem either.
