• HT Link Sync Error after Ubuntu 10.04 LTS Installation

  - by marklab

  Update 1 I just assembled an exact replica of this server, and successfully installed Ubuntu 10.04 LTS in a RAID10 configuration. The success was confirmed by a login to the initial account. There must be a hardware component that is faulty. Since the error mentions HT, which I believe to be Hyper Threading, I will start with the CPUs. Please indicate if this error is more strongly associated with any other piece of hardware. Or make a recommendation of another approach that would be good for this issue. Issue I was attempting to install Ubuntu 10.04 LTS on this system with the board RAID10 configured. However, the installation failed at the partitioning stage by rebooting the system. Upon reboot, there is an error report after POST listing the following: Node0: NB WatchDog Timer Error Node1: HT Link Sync Error Node2: HT Link Sync Error ... Node7: HT Link Sync Error Press F1 to continue/resume. After pressing F1 the system will boot from the Ubuntu 10.04 LTS installation disc. However, it will fail at the same stage, and go through the same process from there. Hardware CPU: AMD OPTERON X12 6172 G34 2.1G 18MB Motherboard: Supermicro H8QG6-F HDD: WD Caviar Green 2TB 5.4K RPM Troubleshooting I disabled RAID10 on the system, and installed the Ubuntu on a single drive. It installed successfully. I then went back to a RAID10 setup and attempted to install on the system again, and was able to make it through the partitioning stage. However, upon reboot, the system reported: Error: file not found, and then booted me into the Grub Rescue console. I feel I have aggravated the problem at this point because when I attempted to install from the boot disc again, the system reboots upon hitting enter to even start the installation process. It does the same thing when trying to boot from an Ubuntu 11 disc. I have not been able to find any information on this HT Link Sync Error, which I feel may have started the problems I am experiencing now with the installation of the OS. I am also aware that Ubuntu is said not to be supported by the motherboard according to Supermicro's site. However, since I was able to install it successfully on a single drive, I do not believe it is incompatible. I would like to know a reason for why it's failing to install on/off.

• SQL Server High Availability - Mirroring with MSCS?

  - by David

  I'm looking at options for high-availability for my SQL Server-powered application. The requirements are: HA protection from storage failure. Data accessibility when one of the DB servers is undergoing software updates (e.g. planned outage for Windows Update / SQL Server service-packs). Must not involve much in the way of hardware procurement. The application is an ASP.NET web application. The web application's users have their own database instances. I've seen two main options: SQL Server failover clustering, and SQL Server mirroring. I understand that SQL Server Failover Clustering requires the purchasing of a shared disk array and doesn't offer any protection if the shared storage goes down (so the documentation recommends to set up a Mirroring between two clusters). Database Mirroring seems the cheaper option (as it only requires two database servers and a simple witness box) - but I've heard it doesn't work well when you have a large number of databases. The application I'm developing involves giving each client their own database for their application - there could be hundreds of databases. Setting up the mirroring is no problem thanks to the automation systems we have in place. My final point concerns how failover works with respect to client connections - SQL Server Failover Clustering uses MSCS which means that the cluster is invisible to clients - a connection attempt might fail during the failover, but a simple reconnect will have it working again. However mirroring, as far as I know, requires that the client be aware of the mirrored partners: if the client cannot connect to the primary server then it tries the secondary server. I'm wondering how this work with respect to Connection Pooling in ASP.NET applications - does the client connection failovering mean that there's a potential 2-second (assuming 2000ms TCP timeout policy) pause when the connection pool tries the primary server on every connection attempt? I read somewhere that Mirroring can be used on top of MSCS which means that the client does not need to be aware of mirroring (so there wouldn't be any potential delays during connection, and also that no changes would need to be made to the client, not even the connection string) - however I'm finding it hard to get documentation or white papers on this approach. But if true, then it means the best method is then Mirroring (for HA) with MSCS (for client ignorance and connection performance). ...but how does this scale to a server instance that might contain hundreds of mirrored databases?

• Is dual-booting an OS more or less secure than running a virtual machine?

  - by Mark

  I run two operating systems on two separate disk partitions on the same physical machine (a modern MacBook Pro). In order to isolate them from each other, I've taken the following steps: Configured /etc/fstab with ro,noauto (read-only, no auto-mount) Fully encrypted each partition with a separate encryption key (committed to memory) Let's assume that a virus infects my first partition unbeknownst to me. I log out of the first partition (which encrypts the volume), and then turn off the machine to clear the RAM. I then un-encrypt and boot into the second partition. Can I be reasonably confident that the virus has not / cannot infect both partitions, or am I playing with fire here? I realize that MBPs don't ship with a TPM, so a boot-loader infection going unnoticed is still a theoretical possibility. However, this risk seems about equal to the risk of the VMWare/VirtualBox Hypervisor being exploited when running a guest OS, especially since the MBP line uses UEFI instead of BIOS. This leads to my question: is the dual-partitioning approach outlined above more or less secure than using a Virtual Machine for isolation of services? Would that change if my computer had a TPM installed? Background: Note that I am of course taking all the usual additional precautions, such as checking for OS software updates daily, not logging in as an Admin user unless absolutely necessary, running real-time antivirus programs on both partitions, running a host-based firewall, monitoring outgoing network connections, etc. My question is really a public check to see if I'm overlooking anything here and try to figure out if my dual-boot scheme actually is more secure than the Virtual Machine route. Most importantly, I'm just looking to learn more about security issues. EDIT #1: As pointed out in the comments, the scenario is a bit on the paranoid side for my particular use-case. But think about people who may be in corporate or government settings and are considering using a Virtual Machine to run services or applications that are considered "high risk". Are they better off using a VM or a dual-boot scenario as I outlined? An answer that effectively weighs any pros/cons to that trade-off is what I'm really looking for in an answer to this post. EDIT #2: This question was partially fueled by debate about whether a Virtual Machine actually protects a host OS at all. Personally, I think it does, but consider this quote from Theo de Raadt on the OpenBSD mailing list: x86 virtualization is about basically placing another nearly full kernel, full of new bugs, on top of a nasty x86 architecture which barely has correct page protection. Then running your operating system on the other side of this brand new pile of shit. You are absolutely deluded, if not stupid, if you think that a worldwide collection of software engineers who can't write operating systems or applications without security holes, can then turn around and suddenly write virtualization layers without security holes. -http://kerneltrap.org/OpenBSD/Virtualization_Security By quoting Theo's argument, I'm not endorsing it. I'm simply pointing out that there are multiple perspectives here, so I'm trying to find out more about the issue.

• How Do I Restrict Repository Access via WebSVN?

  - by kaybenleroll

  I have multiple subversion repositories which are served up through Apache 2.2 and WebDAV. They are all located in a central place, and I used this debian-administration.org article as the basis (I dropped the use of the database authentication for a simple htpasswd file though). Since then, I have also started using WebSVN. My issue is that not all users on the system should be able to access the different repositories, and the default setup of WebSVN is to allow anyone who can authenticate. According to the WebSVN documentation, the best way around this is to use subversion's path access system, so I looked to create this, using the AuthzSVNAccessFile directive. When I do this though, I keep getting "403 Forbidden" messages. My files look like the following: I have default policy settings in a file: <Location /svn/> DAV svn SVNParentPath /var/lib/svn/repository Order deny,allow Deny from all </Location> Each repository gets a policy file like below: <Location /svn/sysadmin/> Include /var/lib/svn/conf/default_auth.conf AuthName "Repository for sysadmin" require user joebloggs jimsmith mickmurphy </Location> The default_auth.conf file contains this: SVNParentPath /var/lib/svn/repository AuthType basic AuthUserFile /var/lib/svn/conf/.dav_svn.passwd AuthzSVNAccessFile /var/lib/svn/conf/svnaccess.conf I am not fully sure why I need the second SVNParentPath in default_auth.conf, but I just added that today as I was getting error messages as a result of adding the AuthzSVNAccessFile directive. With a totally permissive access file [/] joebloggs = rw the system worked fine (and was essentially unchanged), but as I soon as I start trying to add any kind of restrictions such as [sysadmin:/] joebloggs = rw instead, I get the 'Permission denied' errors again. The log file entries are: [Thu May 28 10:40:17 2009] [error] [client 89.100.219.180] Access denied: 'joebloggs' GET websvn:/ [Thu May 28 10:40:20 2009] [error] [client 89.100.219.180] Access denied: 'joebloggs' GET svn:/sysadmin What do I need to do to get this to work? Have configured apache wrong, or is my understanding of the svnaccess.conf file incorrect? If I am going about this the wrong way, I have no particular attachment to my overall approach, so feel free to offer alternatives as well. UPDATE (20090528-1600): I attempted to implement this answer, but I still cannot get it to work properly. I know most of the configuration is correct, as I have added [/] joebloggs = rw at the start and 'joebloggs' then has all the correct access. When I try to go repository-specific though, doing something like [/] joebloggs = rw [sysadmin:/] mickmurphy = rw then I got a permission denied error for mickmurphy (joebloggs still works), with an error similar to what I already had previously [Thu May 28 10:40:20 2009] [error] [client 89.100.219.180] Access denied: 'mickmurphy' GET svn:/sysadmin Also, I forgot to explain previously that all my repositories are underneath /var/lib/svn/repository UPDATE (20090529-1245): Still no luck getting this to work, but all the signs seem to be pointing to the issue being with path-access control in subversion not working properly. My assumption is that I have not conf

• shell script to start multiple Java programs from a directory at boot

  - by zcourts

  I'm not sure if this is the best approach to this, It's my first time doing all of this (including writing shell scripts). OS: Centos My problem: I want to start multiple shell scripts at boot. One of the shell scripts is to start my own services and 3 others are for third party services. The shell script to start my own services will be looking for jar files. I currently have two services (will change), written in Java. All services are named under convention prefix-service-servicename What I've done: I created the following directory structure /home/username/scripts init.sh boot/ boot/startthirdprtyservice1.sh boot/startthirdprtyservice2.sh boot/startthirdprtyservice3.sh boot/startmyservices.sh /home/username/services prefix-lib-libraryname.jar prefix-lib-libraryname.jar prefix-service-servicename.jar prefix-service-servicename.jar prefix-service-servicename.jar In init.sh I have the following: #!/bin/sh #This scripts run all executable scripts in the boot directory at boot #done by adding this script to the file /etc/rc.d/rc.local #nohup #run-parts /home/username/scripts/boot/* #for each file in the boot dir... # ignore the HUP (hangup) signal for s in ./boot/*;do if [ -x $s ]; then echo "Starting $s" nohup $s & fi done echo "Done starting bootup scripts " echo "\n" In the script boot/startmyservices.sh I have #!/bin/sh fnmatch () { case "$2" in $1) return 0 ;; esac ; return 1 ; } ##sub strin to match for SUBSTRING="prefix-service" for s in /home/username/services/*;do if [ -x $s ]; then #match service in the filename , i.e. only services are started if fnmatch "$SUBSTRING" "$s" ; then echo "Starting $s " nohup $s & fi fi done echo "Done starting Services" echo "\n" Finally: Usually you can stick a program in /etc/rc.d/rc.local for it to be run at boot but I don't think this works in this case, or rather I don't know what to put in there I've just learnt how to do this by reading up a bit so I'm not sure its particularly the best thing to do so any advice is appreciated. When I run init.sh nohup.out contains Starting the thirdparty daemon... thirdparty started... .... but nothing from myservices.sh and my Java services aren't running I'm not sure where to start debugging or what could be going wrong. Edit Found some issues and got it to work, used -x instead of -n to check if the string is none zero, needed the sub string check to also be if [[ $s = $SUBSTRING ]] ; then and this last one was just stupid, missing java -jar in front of $s Still unsure of how to get init.sh to run at boot though

• Puppet - Possible to use software design patterns in modules?

  - by Mike Purcell

  As I work with puppet, I find myself wanting to automate more complex setups, for example vhosts for X number of websites. As my puppet manifests get more complex I find it difficult to apply the DRY (don't repeat yourself) principle. Below is a simplified snippet of what I am after, but doesn't work because puppet throws various errors depending up whether I use classes or defines. I'd like to get some feed back from some seasoned puppetmasters on how they might approach this solution. # site.pp import 'nodes' # nodes.pp node nodes_dev { $service_env = 'dev' } node nodes_prod { $service_env = 'prod' } import 'nodes/dev' import 'nodes/prod' # nodes/dev.pp node 'service1.ownij.lan' inherits nodes_dev { httpd::vhost::package::site { 'foo': } httpd::vhost::package::site { 'bar': } } # modules/vhost/package.pp class httpd::vhost::package { class manage($port) { # More complex stuff goes here like ensuring that conf paths and uris exist # As well as log files, which is I why I want to do the work once and use many notify { $service_env: } notify { $port: } } define site { case $name { 'foo': { class 'httpd::vhost::package::manage': port => 20000 } } 'bar': { class 'httpd::vhost::package::manage': port => 20001 } } } } } That code snippet gives me a Duplicate declaration: Class[Httpd::Vhost::Package::Manage] error, and if I switch the manage class to a define, and attempt to access a global or pass in a variable common to both foo and bar, I get a Duplicate declaration: Notify[dev] error. Any suggestions how I can implement the DRY principle and still get puppet to work? -- UPDATE -- I'm still having a problem trying to ensure that some of my vhosts, which may share a parent directory, are setup correctly. Something like this: node 'service1.ownij.lan' inherits nodes_dev { httpd::vhost::package::site { 'foo_sitea': } httpd::vhost::package::site { 'foo_siteb': } httpd::vhost::package::site { 'bar': } } What I need to happen is that sitea and siteb have the same parent "foo" folder. The problem I am having is when I call a define to ensure the "foo" folder exists. Below is the site define as I have it, hopefully it will make sense what I am trying to accomplish. class httpd::vhost::package { File { owner => root, group => root, mode => 0660 } define site() { $app_parts = split($name, '[_]') $app_primary = $app_parts[0] if ($app_parts[1] == '') { $tpl_path_partial_app = "${app_primary}" $app_sub = '' } else { $tpl_path_partial_app = "${app_primary}/${app_parts[1]}" $app_sub = $app_parts[1] } include httpd::vhost::log::base httpd::vhost::log::app { $name: app_primary => $app_primary, app_sub => $app_sub } } } class httpd::vhost::log { class base { $paths = [ '/tmp', '/tmp/var', '/tmp/var/log', '/tmp/var/log/httpd', "/tmp/var/log/httpd/${service_env}" ] file { $paths: ensure => directory } } define app($app_primary, $app_sub) { $paths = [ "/tmp/var/log/httpd/${service_env}/${app_primary}", "/tmp/var/log/httpd/${service_env}/${app_primary}/${app_sub}" ] file { $paths: ensure => directory } } } The include httpd::vhost::log::base works fine, because it is "included", which means it is only implemented once, even though site is called multiple times. The error I am getting is: Duplicate declaration: File[/tmp/var/log/httpd/dev/foo]. I looked into using exec, but not sure this is the correct route, surely others have had to deal with this before and any insight is appreciated as I have been grappling with this for a few weeks. Thanks.

• how to notify a program of another program? dll? directory? path?

  - by Brady Trainor

  I am trying to experiment with GNUS email in Emacs, in Windows (EDIT: x64 bit). I've got it to work in Ubuntu, but struggling with it in Windows. From http://www.gnu.org/software/emacs/manual/html_mono/emacs-gnutls.html#Help-For-Users I read in second paragraph: This is a little bit trickier on the W32 (Windows) platform, but if you have the GnuTLS DLLs (available from http://sourceforge.net/projects/ezwinports/files/ thanks to Eli Zaretskii) in the same directory as Emacs, you should be OK. I have downloaded and unzipped the gnutls-3.0.9-w32-bin package, but am not sure what to do with it. I have tried putting it in Program Files (x86), which is "the same directory as Emacs". I have tried putting it in the emacs-24.3 folder. I consider merging all the folders in between the two, but am hesitant as that seems a difficult troubleshoot attempt compared to my knowledge on these matters. I think Emacs needs to somehow see the gnutls binaries and/or dlls. My knowledge is limited on this. I've also struggled to understand PATHs for sometime now, and am not sure if that approach is relevant here. FYI, the emacs directory contains folders labeled bin, etc, info, leim, lisp and site-lisp. The gnutls directory contains folder labeled bin, include, lib and share. Hmm, now I'm finding lots of links on adding paths. Still, I'm skeptical that I would only add gnutls.exe path, as it seems the dlls are needed. Some additional data for Ramhound's first comment I have been attempting the (require 'gnutls) route. This seems to be the most relevant parts in the log: Opening connection to imap.gmail.com via tls... gnutls.c: [1] (Emacs) GnuTLS library not found Opening TLS connection to `imap.gmail.com'... Opening TLS connection with `gnutls-cli --insecure -p 993 imap.gmail.com'...failed Opening TLS connection with `gnutls-cli --insecure -p 993 imap.gmail.com --protocols ssl3'...failed Opening TLS connection with `openssl s_client -connect imap.gmail.com:993 -no_ssl2 -ign_eof'...failed Opening TLS connection to `imap.gmail.com'...failed I am not sure what "in stallion" means. Emacs seems to have installed itself in program files (x86), so I assume it is 32 bit. I can try and figure out how to double check, but did not realize I would get such fast response time, and am headed out right now. I will try merging the files later tonight?

• broken apache .htaccess (mod_rewrite)

  Hey there, I'm running into an apache mod_rewrite configuration issue on one of our machines. Has anyone encountered / overcome anyone of these issues.

• Upgrading TFS 2005 to TFS 2010 fails at "Executing servicing step Upgrade Version Control Identities"

  - by nadeemmar

  Hi all, I have been trying to upgrade our TFS 2005 to TFS 2010 but with no luck so far. I went through the TFS Installation guide and many upgrade guides but with no luck in overcoming the issue I am facing which seems to be unique and different to other described issues. In our company, we have a domain forest with several domains. Lets say domain A, B, and C. TFS is in domain A and has users from all these three domains. All domains have trust reltionships between them. However, domain C was deleted several months ago. In the upgrade process, whenever I reach the collection upgrade step, the following error is raised: [Info @09:57:50.997] [2010-12-29 09:55:47Z][Informational] Step Data: ExtensionType = Microsoft.TeamFoundation.VersionControl.Server.PlugIns.WorkspaceSecurityNamespaceExtension [Info @09:57:50.997] [2010-12-29 09:55:47Z] Servicing step Create VersionControl Security Namespaces passed.

With a bit of googling, I figured out that TFSConfig Identities command can be used to remap users from one domain to the other. I went ahead and created local users that matches the users we have from domain C and ran the TFSConfig Identities /Change command and it executed successfully. However, I still get the same error. I am stuck and can't figure out how to move forward :( I need your expertise, has anyone faced this issue before? Do I need to change these identities on TFS 2005 before I commence the upgrade? I forgot to mention, I am following the upgrade with a move approach. I created a virtual machine for testing the upgrade. Installed SQL server 2008, restored the TFS databases and installed TFS 2010 and ran the upgrade wizard. Regards, Nadeem

• Email delivery management grievances

  - by joxl

  The question I have may be more of principle than anything else, but here's my dilemma. I manage an email system for a small company (about 20 email users). We own a plain-letter .com domain name through Network Solutions. Our email service is hosted by Google Apps. Recently (Feb. 2011) we've been having customers report that they aren't getting our emails. Upon further investigation it seems that the failed emails are all to a common (well known) domain. We have not received any bounce messages for the emails. We've also contacted a few of the intended recipients, who have reported that the messages are not in their spam box; they simply did not receive anything. In these cases we re-sent the same email to an alternate address on another domain, which was successful received. One customer contacted their email provider about the issue. The provider recommended that we submit a form to be white-listed by their domain. Here's where my problem begins. I feel like this is heading down a slippery slope. Doesn't this undermine the very principle of email? If this is the appropriate action to take in these situations where will it end? In theory (following this model) it could be argued that eventually one will first need to "whitelist" (or more appropriately termed "authenticate") themselves with an email host before actually sending any messages. More to this point, what keeps the "bad" spammers from doing the same thing...? We've just gone full circle. I know avoiding anti-spam measures is a big cat-and-mouse game, but I think this is the wrong way of "patching" the problem. Email standards say that messages should not just disappear silently. I have a problem supporting a model that says "you must do < this to make sure your emails aren't ignored". I have a notion to call the provider and voice my complaint, although I have a feeling it will probably fall on deaf ears. Am I missing something here? Is this an acceptable approach to email spam problems? What should I do?

• Problems migrating an EBS backed instance over AWS Regions

  - by gshankar

  Note: I asked this question on the EC2 forums too but haven't received any love there. Hopefully the ServerFault community will be more awesome. The new AWS Sydney region opening up is something that we've been waiting for for a long time but I'm having a lot of trouble migrating our instances over from N. California. I managed to migrate 1 instance over using CloudyScripts to move a snapshot and then firing up a new instance in the Sydney region. This was a very new instance so both the source and destination were running on a Ubuntu 12.04 LTS server and I had no issues there. However, the rest of our instances are all Ubuntu 10.04 LTS and with these, I'm having a lot of problems. I've tried following: 1- following the AWS whitepaper on moving instances which was given to us at the recent Customer Appreciation Day in Sydney where the new region was launched. The problem with this approach was with the last step (Step 19) here you register the image: ec2-register -s snap-0f62ec3f -n "Wombat" -d "migrated Wombat" --region ap-southeast-2 -a x86_64 --kernel aki-937e2ed6 --block-device-mapping "/dev/sdk=ephemeral0" I keep getting this error: Client.InvalidAMIID.NotFound: The AMI ID 'ami-937e2ed6' does not exist which I think is due to the kernel_id not existing in the Sydney region? 2- Using CloudyScripts to move a snapshot and then creating a new volume and attaching to a new instance in Sydney This results in the instance just hanging on boot and failing the status checks. I can't SSH in or look at the server log I suspect that my issue is with finding the right kernel_id for the volume in the new region. However I can't seem to work out how to go about finding this kernel_id, the ones I've tried (from the original instance) don't result in the Client.InvalidAMIID.NotFound: The AMI ID 'ami-937e2ed6' error and any other kernel_id just won't boot. I've tried both 12.04 and 10.04 versions of Ubuntu. Nothing seems to work, I've been banging my head against a wall for a while now, please help! New (broken) instance i-a1acda9b ami-9b8611a1 aki-31990e0b Source instance i-08a6664e ami-b37e2ef6 aki-937e2ed6 p.s. I also tried following this guide on updating my Ubuntu LTS version to 12.04 before doing the migration but it didn't seem to work either, still getting stuck on updating the kernel_id http://ubuntu-smoser.blogspot.com.au/2010/04/upgrading-ebs-instance.html

• Open a terminal window & run command, then close the terminal window if command completed successfully?

  - by Caspar

  I'm trying to write a script to do the following: Open a terminal window which runs a long running command (Ideally) move the terminal window to the top left corner of the screen using xdotool Close the terminal window only if the long running command exited with a zero return code To put it in Windows terms, I'd like to have the Linux equivalent of start cmd /c long_running_cmd if long_running_cmd succeeds, and do the equivalent of start cmd /k long_running_cmd if it fails. What I have so far is a script which starts xterm with a given command, and then moves the window as desired: #!/bin/bash # open a new terminal window in the background with the long running command xterm -e ~/bin/launcher.sh ./long_running_cmd & # move the terminal window (requires window process to be in background) sleep 1 xdotool search --name launcher.sh windowmove 0 0 And ~/bin/launcher.sh is intended to run whatever is passed as a command line argument to it: #!/bin/bash # execute command line arguments $@ But, I haven't been able to get the xterm window to close after long_running_cmd is done. I think something like xterm -e ~/bin/launcher.sh "./long_running_cmd && kill $PPID" & might be what I'm after, so that xterm is launched in the background and it runs ./long_running_cmd && kill $PPID. So the shell in the xterm window then runs the long running command and if it completes successfully, the parent process of the shell (i.e. the process owning the xterm window) is killed, thereby closing the xterm window. But, that doesn't work: nothing happens, so I suspect my quoting or escaping is incorrect, and I haven't been able to fix it. An alternate approach would be to get the PID of long_running_cmd, use wait to wait for it to finish, then kill the xterm window using kill $! (since $! refers to last task started in the background, which will be the xterm window). But I can't figure out a nice way to get the PID & exit value of long_running_cmd out of the shell running in the xterm window and into the shell which launched the xterm window (short of writing them to a file somewhere, which seems like it should be unnecessary?). What am I doing wrong, or is there an easier way to accomplish this?

• How Do I Restrict Repository Access via WebSVN?

  - by kaybenleroll

  I have multiple subversion repositories which are served up through Apache 2.2 and WebDAV. They are all located in a central place, and I used this debian-administration.org article as the basis (I dropped the use of the database authentication for a simple htpasswd file though). Since then, I have also started using WebSVN. My issue is that not all users on the system should be able to access the different repositories, and the default setup of WebSVN is to allow anyone who can authenticate. According to the WebSVN documentation, the best way around this is to use subversion's path access system, so I looked to create this, using the AuthzSVNAccessFile directive. When I do this though, I keep getting "403 Forbidden" messages. My files look like the following: I have default policy settings in a file: <Location /svn/> DAV svn SVNParentPath /var/lib/svn/repository Order deny,allow Deny from all </Location> Each repository gets a policy file like below: <Location /svn/sysadmin/> Include /var/lib/svn/conf/default_auth.conf AuthName "Repository for sysadmin" require user joebloggs jimsmith mickmurphy </Location> The default_auth.conf file contains this: SVNParentPath /var/lib/svn/repository AuthType basic AuthUserFile /var/lib/svn/conf/.dav_svn.passwd AuthzSVNAccessFile /var/lib/svn/conf/svnaccess.conf I am not fully sure why I need the second SVNParentPath in default_auth.conf, but I just added that today as I was getting error messages as a result of adding the AuthzSVNAccessFile directive. With a totally permissive access file [/] joebloggs = rw the system worked fine (and was essentially unchanged), but as I soon as I start trying to add any kind of restrictions such as [sysadmin:/] joebloggs = rw instead, I get the 'Permission denied' errors again. The log file entries are: [Thu May 28 10:40:17 2009] [error] [client 89.100.219.180] Access denied: 'joebloggs' GET websvn:/ [Thu May 28 10:40:20 2009] [error] [client 89.100.219.180] Access denied: 'joebloggs' GET svn:/sysadmin What do I need to do to get this to work? Have configured apache wrong, or is my understanding of the svnaccess.conf file incorrect? If I am going about this the wrong way, I have no particular attachment to my overall approach, so feel free to offer alternatives as well. UPDATE (20090528-1600): I attempted to implement this answer, but I still cannot get it to work properly. I know most of the configuration is correct, as I have added [/] joebloggs = rw at the start and 'joebloggs' then has all the correct access. When I try to go repository-specific though, doing something like [/] joebloggs = rw [sysadmin:/] mickmurphy = rw then I got a permission denied error for mickmurphy (joebloggs still works), with an error similar to what I already had previously [Thu May 28 10:40:20 2009] [error] [client 89.100.219.180] Access denied: 'mickmurphy' GET svn:/sysadmin Also, I forgot to explain previously that all my repositories are underneath /var/lib/svn/repository UPDATE (20090529-1245): Still no luck getting this to work, but all the signs seem to be pointing to the issue being with path-access control in subversion not working properly. My assumption is that I have not conf

• Windows 2003 GPO Software Restrictions

  - by joeqwerty

  We're running a Terminal Server farm in a Windows 2003 Domain, and I found a problem with the Software Restrictions GPO settings that are being applied to our TS servers. Here are the details of our configuration and the problem: All of our servers (Domain Controllers and Terminal Servers) are running Windows Server 2003 SP2 and both the domain and forest are at Windows 2003 level. Our TS servers are in an OU where we have specific GPO's linked and have inheritance blocked, so only the TS specific GPO's are applied to these TS servers. Our users are all remote and do not have workstations joined to our domain, so we don't use loopback policy processing. We take a "whitelist" approach to allowing users to run applications, so only applications that we approve and add as path or hash rules are able to run. We have the Security Level in Software Restrictions set to Disallowed and Enforcement is set to "All software files except libraries". What I've found is that if I give a user a shortcut to an application, they're able to launch the application even if it's not in the Additional Rules list of "whitelisted" applications. If I give a user a copy of the main executable for the application and they attempt to launch it, they get the expected "this program has been restricted..." message. It appears that the Software Restrictions are indeed working, except for when the user launches an application using a shortcut as opposed to launching the application from the main executable itself, which seems to contradict the purpose of using Software Restrictions. My questions are: Has anyone else seen this behavior? Can anyone else reproduce this behavior? Am I missing something in my understanding of Software Restrictions? Is it likely that I have something misconfigured in Software Restrictions? EDIT To clarify the problem a little bit: No higher level GPO's are being enforced. Running gpresults shows that in fact, only the TS level GPO's are being applied and I can indeed see my Software Restictions being applied. No path wildcards are in use. I'm testing with an application that is at "C:\Program Files\Application\executable.exe" and the application executable is not in any path or hash rule. If the user launches the main application executable directly from the application's folder, the Software Restrictions are enforced. If I give the user a shortcut that points to the application executable at "C:\Program Files\Application\executable.exe" then they are able to launch the program. EDIT Also, LNK files are listed in the Designated File Types, so they should be treated as executable, which should mean that they are bound by the same Software Restrictions settings and rules.

• Backing up data stored on Amazon S3

  - by Fiver

  I have an EC2 instance running a web server that stores users' uploaded files to S3. The files are written once and never change, but are retrieved occasionally by the users. We will likely accumulate somewhere around 200-500GB of data per year. We would like to ensure this data is safe, particularly from accidental deletions and would like to be able to restore files that were deleted regardless of the reason. I have read about the versioning feature for S3 buckets, but I cannot seem to find if recovery is possible for files with no modification history. See the AWS docs here on versioning: http://docs.aws.amazon.com/AmazonS3/latest/dev/ObjectVersioning.html In those examples, they don't show the scenario where data is uploaded, but never modified, and then deleted. Are files deleted in this scenario recoverable? Then, we thought we may just backup the S3 files to Glacier using object lifecycle management: http://docs.aws.amazon.com/AmazonS3/latest/dev/object-lifecycle-mgmt.html But, it seems this will not work for us, as the file object is not copied to Glacier but moved to Glacier (more accurately it seems it is an object attribute that is changed, but anyway...). So it seems there is no direct way to backup S3 data, and transferring the data from S3 to local servers may be time-consuming and may incur significant transfer costs over time. Finally, we thought we would create a new bucket every month to serve as a monthly full backup, and copy the original bucket's data to the new one on Day 1. Then using something like duplicity (http://duplicity.nongnu.org/) we would synchronize the backup bucket every night. At the end of the month we would put the backup bucket's contents in Glacier storage, and create a new backup bucket using a new, current copy of the original bucket...and repeat this process. This seems like it would work and minimize the storage / transfer costs, but I'm not sure if duplicity allows bucket-to-bucket transfers directly without bringing data down to the controlling client first. So, I guess there are a couple questions here. First, does S3 versioning allow recovery of files that were never modified? Is there some way to "copy" files from S3 to Glacier that I have missed? Can duplicity or any other tool transfer files between S3 buckets directly to avoid transfer costs? Finally, am I way off the mark in my approach to backing up S3 data? Thanks in advance for any insight you could provide!

• PSU failing or Mainboard failing?

  - by Andrei Rinea

  I am having some troubles lately powering on my desktop workstation. While starting up the PC after being off for hours (usually at least 8 hours) it randomly fails to do so. What happens is that : I press the power button; nothing happens I can hear a moderate buzzing noise at the back of the PC (near the PSU); but I can't say for sure that it's not from the mainboard. If I insist pressing the power button a few times in 1-2 minutes it'll start Another route would be that instead of (3) I will plug off the power cable from the PSU and wait for 30 seconds. Then I will press the power on and keep it for 30-60 seconds (I had some success at notebooks with a similar approach). Then I will plug back the cable in the PSU, press only once the power button and it will start normally. Also while running normally I keep hearing some low buzzing which seems to be fan-RPM-related (i.e. when processing images or doing CPU intensive work). What should I look into? UPDATE It's getting worse. It took more than 10 retries today and almost 20 minutes to start the computer. I tried the paperclip trick and the PSU behaves perfectly. I managed to start the computer like so : I pressed the on-button a few times and then left the PC in a pre-startup state (the fans were working the buzzing noise was strong and I went to eat. I thought I won't lit the house on fire so fast and without smelling. Back, after 10-15 min the computer booted up! Discussed with a fellow at Intel and he told me the capacitors on the mainboard are probably a bit shot. If they are shot, he said, it should start up warm perfectly. So I did restart it, warm, a few times (5 sec cooldown and then 40 sec cooldown and it started up perfectly). I can either replace the capacitors on the mainboard (doesn't sound worth it or replace the mainboard (this one sucks too :)) ) FINAL INFO : It was the PSU after all. Although it was powering the IDEs and SATAs the Mainboard power module was failing. I bought another mainboard just to find out that this wasn't the cause. Now I'll have to return it somehow. The spare PSU is now in the computer and doing well.. Although larger (500W), it's like a plane taking off.. I need a better one.

• Monitoring the status of accounts with IT Service providers (ISP, Domain Registrar etc.)

  - by Sholom

  Hi All, Short version: You have software that tells you when your servers power-outlet is down. It monitors multiple servers from one management console, alerts you when something is wrong etc. Does anyone know of software that will let me take the same approach to monitor if the money-outlet (the bill!) is down (not paid) to my IT Services providers (ISP, Domain Registrar, MX Backup service etc). I need a top down, centrally managed service that is capable of sending out alerts. Just like the one that monitors my own exchange server etc. I don't mind if i have to manually enter every payment. Long version: Our very likable but absent minded bookkeeper keeps neglecting to pay our IT vendors on time. Just this past week our internet service was disconnected. Same could happen to many other mission critical accounts (domain registrar, backup MX, anti-virus license, HackerSafe (McAfee secure) service and even an 800 number to name a few). As the sysadmin, i monitor my severs to make sure they are plugged into the power-outlet. I believe i should also monitor my services to make sure they are plugged in to their money-outlet. To compound the problem, when the power goes out someone else will likely notice and notify me. But if a bill is not payed, no one will ever notice until service is lost. Lost as in losing our domain name which would cause a lot more damage then the power failing on our server. [Solution] = [Doesn't work because]: Retrain the bookkeeper = Wishful thinking. Notify my manager = Already have (via email). Protects me, does not solve problem. Fire bookkeeper = What makes you so sure the next one will never forget? Bottom line: Humans are humans and sooner or later something critical will be royally messed up. We need to partner with a machine to help us out here. Anybody have the same problem? What software/solution do you use? I would like software that emails me when a bill is passed due just like i get an email when the power outlet fails. Anyone hear of anything like that? Thanks

• Cannot Send Item error in Outlook - permissions to registry?

  - by Tim Alexander

  The issue I am trying to solve is to do with users getting a Cannot Send Item error in Outlook 2007 connecting to Exchange 2007. Basically if there is an image in the email (either one they have pasted in or one from another email in the chain) they get a "Cannot Send Item" error. Initially thought it was a citrix issue but users get it when they RDP to a server as well. Changing the message to Rich Text works 80% of the time but I do not think this is a solution but more of a temporary workaround. After some troubleshooting we found that the error can be fixed by adding the user as a member of the local power users group. of course this is not really a fix. My thoughts were that the ability of a power user to add/remove software may give them more access to the registry which might allow them to get round a restriction that is in place for a normal user. I have tried going through a procmon but the wealth of information is confusing. It initially looked like it may be an Outlook 2007 email security setting but this does not change between power user and normal user (set to 1 in the registry, "Use the security setting from Outlook Security Settings Public Folders"). I am struggling to fine tune my troubleshooting to work out exactly what is blocking it. Has anyone had an experience with an error similar to this? Or are there any tips for trying to track down issues via procmon as I must admit my approach seems somewhat lacking :) EDIT: So I have trawled through the two logs we have from process monitor (one as a power user and one a normal user). annoyingly I can find no obvious difference where something is denied access. There are more access denied events in the normal user log but these are quickly followed by sucessful entries to the same path fractions of a second later. The only thing that does stand out is an access denied to HKCR.html. This does not even appear in the power user version of the log. From what I understand this helps determine the default browser which ties in nicely with the fact that 9 out of 10 times you can send the message as Rich Text. EDIT: Looks like KB2509470 was causing the issue. Not really sure why but when I can work out what it does and why it causes the problem will post here unless anyone beats me to it!

• Scaling a video processing application on EC2?

  - by Stpn

  I am approaching the need to scale a video-processign application that runs on EC2. So far the setup is one machine: Backbonejs frontend Rails 3.2 Postgresql Resque + S3 for storage The flow of the app is as follows: 1) Request from frontend. Upload a video. 2) Storing video 3) Quering external APIs. 4) Processing / encoding videos. 5) Post to frontend. I can separate the backend and frontend without any problems, but when it comes to distributing the backend between several servers I am a bit puzzled. I can probably come up with a temporary solution (like just duplicating apps making several instances), but since I don't really have expertise in backend system administration, there can be some fundamental mistakes.. Also I would rather have something that is scalable. I wonder if anyone can give some feedback on the following plan: A) Frontend machine. Just frontend, talks to backend via REST Api of sorts. B) Backend server (BS), main database. Gets request from 1), posts to 2) saves uploads to 3) C) S3 storage. D) Server for quering APIs. Basically just a Resque workers, that post info back to 2) E) Server for video encoding. Processes videos uploaded on 3) and uploads them back. So I will have: A)frontend \ \ B)MAIN_APP/DB ----- C)S3 Storage (Files) / \ / / \ / D)ExternalAPI_queries E)Video_Processing (redundant DB) (redundant DB) All this will supposedly talk to each other via HTTP requests. My reason for this is that Video Processing part is really the most resource-intensive and I would just run barebones application that accepts requests and starts processing them. Questions: 1) In this setup I will have the main database at B) and all other servers will communicate with it via HTTP requests (and store duplicates of databases also I guess..for safety reasons). Is it the right approach or should I have 1 database that everyone connects to (how then?) 2) Is it a good idea to separate API queries from Video Processing part? Logically they are very close (processing is determined by the result of API queries), but resource-wise Video Processing is waaay more intensive. 3) what should I use to distribute calls between backend apps based on load?

• I want to virtualize my workstation (Tier 1), Looking for Bare Metal Hypervisor for consumer grade components

  - by Chase Florell

  I find myself in this similar bind at least once a year. The bind whereby I'm either upgrading a motherboard, or an OS hard drive. It drives me crazy to have to reinstall Windows, Visual Studio, all my addins, reconfigure my settings etc... every single time. I have a layout and I like and I want to stick with it. My question is... Is there a Bare Metal Hypervisor on the market that will enable me to virtualize my consumer grade workstation? I really want to avoid Host/Client virtualization. Bare Metal is definitely a better way to go for my needs. Is this a good approach, or am I going to suffer some other undesirable side effects by doing this? Clarification My machine has very limited purposes. My primary use is Visual Studio 2010 Professional where I develop ASP.NET MVC Web Applications. The second piece of software that I use (that's system intensive) is Photoshop CS3. Beyond that, my applications are limited to Outlook, Internet Explorer, Firefox, Opera, Chrome, LinqPad, and various other (small) apps. Beyond this, I'm considering working on a node.js project and might run ubuntu on the same hypervisor if possible. System Specs: Gigabyte Motherboard Intel i7 920 12 GB Ram basic 500GB 7200RPM HDD for OS 4 VelociRaptors in Raid 1/0 for build disk Dual GTS250 (512MB) Graphics cards (non SLI) for quad monitors On a side note I also wouldn't be opposed to an alternative suggestion if the limitations are too great. I could install the ESXi (or Zen Server) on my box, and build a separate "thin client" to RDP into the virtual machine. It appears as though RDP supports dual monitors. Edit (Dec 9, 2011) It's been nearly a year since I first asked this question. Since then, there have been a lot of great strides in Hypervisor technology... AND MokaFive is now released for corporate use. I'd love to dig into this question a little more and find out if there is a solid BareMetal Hypervisor for workstations running consumer grade components (IE: not Dell, HP, Lenovo, Etc).

• System failure - need diagnostic recommendation

  - by Ladislav Mrnka

  I have big problem with my computer. Configuration is: Intel i7 + 6x2GB OCZ DDR3 Motheboard: Asus P6T Deluxe V2, HDD controller configured to AHCI Main drive: OCZ Vertex 2 (SSD) - contains all installed programs and system Second drive: Samsung SpinPoint - contains User profiles, ProgramData, virtual machines and databases Third drive: Samsung SpinPoint - data drive + backups OS: Windows 7 Ultimate x64 I have never had any problem with this computer until now. During weekend my computer completely crashed without any reason. Each time I tried to boot to Windows I got BSOD with message BAD_SYSTEM_CONFIG_INFO and automatic restart (I didn't install any new SW or HW). But after restart main OCZ drive was disconnected (not detected by BIOS). When I turned off and on computer, the drive was again connected. It also happend every single time I tried to repair installation somehow. It ended with some error and after restart drive was disconnected. The only thing which worked was format + fresh install. After installing almost everything I wanted to install Visual Studio 2010 Ultimate (complete installation without SQL Server Express). During installation of VS itself I always get BSOD - it is too fast so I'm not able to read description. After restart it searches for all disk drives for really long time and sometimes it changes boot drive so the system is not able to start - Bootmgr not found. After reconfiguring BIOS the system starts. There is no event describing the failure in Event viewer. Installing VS 2010 is absolutely necessary for me. I need help with diagnostic. I need to find where is the problem - I expect that the problem is in OCZ drive or in HDD controller on motherboard but I don't know how to find it. All components still have valid warranty. Can you recommend me some approach or tools to find the problem? Edit: I'm still looking for source of the problem. New information is that Windows are not able to perform check disk (Chkdsk) on the SSD system drive. After restarting it always starts checking drive and in part where files are checked it fails with BSOD - BAD_SYSTEM_CONFIG_INFO. After next restart and skipping check disk tests the system runs.

• 20GB+ worth of emails in my /home what is a better solution for that?

  - by Skinkie

  My email storage requirements are outgrowing anything reasonable with respect to local mail storage. As we speak 99% of my home partition is filled with personal mail in Thunderbirds mail dirs. Needless to say, this is just painful, badly searchable and as history has proven me that backups work, but Thunderbird is capable of loosing a lot of mail very easily. Currently I have an remote IMAPS server (Dovecot) running for my daily mail, accessible from anywhere, which from my own practice works efficiently up to about 1000 emails. Then some archive directories should be used to move mail around. I have been looking into DBMail, but I wonder if I make my case worse or better which such solution. None of the supported database employ string deduplication or string compression out of the box, so is this going to help me with 20GB+ mail? What about falling back to a plain old IMAP server? A filesystem like ZFS would support stuff like GZIP transparently, which could help. Could someone share their thoughts? The 20GB mostly consists of mailinglists, and normal mail. Not things like attachments. To add some clarifications; As we speak, my mail is not server side indexed at all - only my new mail arrives at a remote IMAP server. It is all local storage from former POP3 accounts, local mirrored Gmail and IMAP accounts. In my perspective it is not Thunderbird that sucks, its fileformat that sucks. Regarding the 1000 mails. On the road I am using Alpine and MobileMail, quite happy with both of them, but some management is required to actually manage the mail. Sieve helps a lot with that, but browing through 10.000 e-mails is not fun, especially not on a mobile client. I am quite happy with Dovecot, never had any issues with it. I just wonder if this is the way to go. Or if there are any other better solutions. What my question is: what is the best practice solution that allows 20GB+ mails and is -on demand remotely accessible, easy to backup and archive worthy. It doesn't need to be available 24x7. The final approach I took was installing a local IMAP server (Dovecot), configured it for being my archive, using the following guide: http://en.gentoo-wiki.com/wiki/Dovecot/InstallThunderbird

• nginx rewrite rule to convert URL segments to query string parameters

  - by Nick

  I'm setting up an nginx server for the first time, and having some trouble getting the rewrite rules right for nginx. The Apache rules we used were: See if it's a real file or directory, if so, serve it, then send all requests for / to Director.php DirectoryIndex Director.php If the URL has one segment, pass it as rt RewriteRule ^/([a-zA-Z0-9\-\_]+)/$ /Director.php?rt=$1 [L,QSA] If the URL has two segments, pass it as rt and action RewriteRule ^/([a-zA-Z0-9\-\_]+)/([a-zA-Z0-9\-\_]+)/$ /Director.php?rt=$1&action=$2 [L,QSA] My nginx config file looks like: server { ... location / { try_files $uri $uri/ /index.php; } location ~ \.php$ { fastcgi_pass unix:/var/run/php5-fpm.sock; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include fastcgi_params; } } How do I get the URL segments into Query String Parameters like in the Apache rules above? UPDATE 1 Trying Pothi's approach: # serve static files directly location ~* ^.+\.(jpg|jpeg|gif|css|png|js|ico|html)$ { access_log off; expires 30d; } location / { try_files $uri $uri/ /Director.php; rewrite "^/([a-zA-Z0-9\-\_]+)/$" "/Director.php?rt=$1" last; rewrite "^/([a-zA-Z0-9\-\_]+)/([a-zA-Z0-9\-\_]+)/$" "/Director.php?rt=$1&action=$2" last; } location ~ \.php$ { fastcgi_pass unix:/var/run/php5-fpm.sock; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include fastcgi_params; } This produces the output No input file specified. on every request. I'm not clear on if the .php location gets triggered (and subsequently passed to php) when a rewrite in any block indicates a .php file or not. UPDATE 2 I'm still confused on how to setup these location blocks and pass the parameters. location /([a-zA-Z0-9\-\_]+)/ { fastcgi_pass unix:/var/run/php5-fpm.sock; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME ${document_root}Director.php?rt=$1{$args}; include fastcgi_params; } UPDATE 3 It looks like the root directive was missing, which caused the No input file specified. message. Now that this is fixed, I get the index file as if the URL were / on every request regardless of the number of URL segments. It appears that my location regular expression is being ignored. My current config is: # This location is ignored: location /([a-zA-Z0-9\-\_]+)/ { fastcgi_pass unix:/var/run/php5-fpm.sock; fastcgi_index Director.php; set $args $query_string&rt=$1; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include fastcgi_params; } location / { try_files $uri $uri/ /Director.php; } location ~ \.php$ { fastcgi_pass unix:/var/run/php5-fpm.sock; fastcgi_index Director.php; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include fastcgi_params; }

• Complete machine freezes...at a loss

  - by user28818

  Guys, We built around 12 machines a few months ago to run Ubuntu. They each have the following specs: ASUS Z8NA-D6 motherboard Dual quad core Intel(R) Xeon(R) CPU E5520 @ 2.27GHz OCZ Mod Extreme Pro 500W power supply 12 GB Kingston RAM Nvidia GeForce 9800 GT graphics card My machine ran well for awhile. However, it started experiencing random lockups. These lockups are not X lockups, they are complete system freezes. The nic stops responding, the magic sysrq buttons won't work. The machine is dead. I first suspected RAM. Memtest86 didn't find anything, but I replaced the RAM anyway. Still, lockups. So I replaced the graphics card. Still, more lockups. They became more and more frequent and started to happen 2-3 times a day. So I replaced the motherboard and power supply in one fell swoop. Suddenly, no more lockups! Woohoo! Except, a week later, in the morning, the machine wouldn't wake up. I reset it, started it up, and the log files showed the last entry at around 11 pm the evening before. This has started occurring with more frequency...now just about every morning I come in, the machine is locked up, and has been since the night before. Yesterday, in the 3 weeks since I replaced the motherboard and power supply, the machine actually locked up on in in mid-work. This is the first time since replacing the two (MB and PS) that this happened while I was using it. All others occurred while I was away. I'm at a loss. Nothing is in syslog or message that would indicate a problem around the time of the lockup. Temps are good...I use lmsensors to monitor and have a script that writes the output to file every minute. They never get that high. The only thing I haven't replaced at this point is the case and the harddrives. I doubt either could be the cause. What would you do if you were in my shoes? Is there a troubleshooting approach I'm missing? For the record, all of the other machines, all eleven of them, don't have any problems. They're all running the same version of Ubuntu (Lucid) that I am. Thanks!

• Resetting root password on Fedora Core 3 - serial cable access only

  - by Sensible Eddie

  A little background: We have an old rackmount server running a customised version of Fedora, manufactured by a company called Navaho. The server is a TeamCAT, running some proprietary rubbish called Freedom2. We have to keep it going - the alternative is extraordinarily expensive, and the business is not likely to be running much longer to justify changing things. Through one means or another, it has fallen upon me to try and resolve our lack of root access. The previous admin has fallen under the proverbial bus, and nobody has any clue. We have no access to the root account for this server. ssh is running on the server, and there is one account admin that we can login with, however it has no permission to do anything (ironic...) The only other way into the server is with a null-modem serial cable. This works... up to a point. I can see the BIOS, I can see the post BIOS screen, and then I see "Starting grub", followed by another screen with about four lines of Linux information, but then it stops at that point. The server continues booting, and all services come online after around two minutes, but the serial terminal displays no more information. I understand it is possible to put Linux into "single user mode" to reset a root password, but I have no idea how to do this beyond trying to interrupt it at the grub stage listed above. When I have tried it just froze. It was almost like grub had appeared (since the server did not continue booting) but I couldn't see it on the serial terminal. Which made me think maybe the grub screen has some different serial settings? I don't know... it's the first time I've ever used serial for access! A friend of mine suggested trying to use a Fedora boot CD. We could boot from USB, so something along this approach is possible but again we still can only see what's going on with the serial terminal, so it might not be achievable. Does anyone have any suggestions for things I can try? I appreciate this is a bit of a long shot, but any assistance would be invaluable. *UPDATE 1 - 28/8/12 * - we will be making some attempts on this today and will post further details later!
