  • Juju instances in aganet-state: down after turning them off (and back on) on EC2

    - by Tyler McAdams
    I turned my Juju instances off on EC2 for a while and after bringing them back online they seem to be in an odd state: [code] claude-vm@claude-vm-fusion:~/Documents/Shell Scripts$ juju status 2012-11-17 17:06:44,094 INFO Connecting to environment... 2012-11-17 17:06:45,590 INFO Connected to environment. machines: 0: agent-state: not-started dns-name: ec2-54-242-142-196.compute-1.amazonaws.com instance-id: i-b0996fcf instance-state: running 1: agent-state: down dns-name: ec2-50-19-186-245.compute-1.amazonaws.com instance-id: i-8c8375f3 instance-state: running 2: agent-state: down dns-name: ec2-54-242-255-238.compute-1.amazonaws.com instance-id: i-56807629 instance-state: running services: wordpress: charm: cs:precise/wordpress-9 exposed: true relations: db: - wordpress-db loadbalancer: - wordpress units: wordpress/0: agent-state: down machine: 2 open-ports: - 80/tcp public-address: ec2-54-242-227-57.compute-1.amazonaws.com wordpress-db: charm: cs:precise/mysql-10 relations: db: - wordpress units: wordpress-db/0: agent-state: down machine: 1 public-address: ec2-54-242-212-177.compute-1.amazonaws.com 2012-11-17 17:06:47,274 INFO 'status' command finished successfully [/code] Can I not take my instances down for a while?

  • Python and displaying HTML

    - by Tyler Seymour
    I've gotten pretty comfortable with Python and now I'm looking to make a rudimentary web application. I was somewhat scared of Django and the other Python frameworks so I went caveman on it and decided to generate the HTML myself using another Python script. Maybe this is how you do it anyways - but I'm just figuring this stuff out. I'm really looking for a tip-off on, well, what to do next. My Python script PRINTS the HTML (is this even correct? I need it to be on a webpage!), but now what? Thanks for your continued support during my learning process. One day I will post answers! -Tyler Here's my code: from SearchPhone import SearchPhone phones = ["Iphone 3", "Iphone 4", "Iphone 5","Galaxy s3", "Galaxy s2", "LG Lucid", "LG Esteem", "HTC One S", "Droid 4", "Droid RAZR MAXX", "HTC EVO", "Galaxy Nexus", "LG Optimus 2", "LG Ignite", "Galaxy Note", "HTC Amaze", "HTC Rezound", "HTC Vivid", "HTC Rhyme", "Motorola Photon", "Motorola Milestone", "myTouch slide", "HTC Status", "Droid 3", "HTC Evo 3d", "HTC Wildfire", "LG Optimus 3d", "HTC ThunderBolt", "Incredible 2", "Kyocera Echo", "Galaxy S 4g", "HTC Inspire", "LG Optimus 2x", "Samsung Gem", "HTC Evo Shift", "Nexus S", "LG Axis", "Droid 2", "G2", "Droid x", "Droid Incredible" ] print """<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>table of phones</title> </head> <body> </body> </html> """ #table print '<table width="100%" border="1">' for x in phones: y = SearchPhone(x) print "\t<tr>" print "\t\t<td>" + str(y[0]) + "</td>" print "\t\t<td>" + str(y[1]) + "</td>" print "\t\t<td>" + str(y[2]) + "</td>" print "\t\t<td>" + str(y[3]) + "</td>" print "\t\t<td>" + str(y[4]) + "</td>" print "\t</tr>" print "</table>

  • NHibernate unable to create SessionFactory

    - by Tyler
    I'm having a bit of trouble setting up NHibernate, and I'm not too sure what the problem is exactly. I'm attempting to save a domain object to the database (Oracle 10g XE). However, I'm getting a TypeInitializationException while trying to create the ISessionFactory. Here is what my hibernate.cfg.xml looks like: <?xml version="1.0" encoding="utf-8"?> <hibernate-configuration xmlns="urn:nhibernate-configuration-2.2" > <session-factory name="MyProject.DataAccess"> <property name="connection.driver_class">NHibernate.Driver.OracleClientDriver</property> <property name="connection.connection_string"> User ID=myid;Password=mypassword;Data Source=localhost </property> <property name="show_sql">true</property> <property name="dialect">NHibernate.Dialect.OracleDialect</property> <property name="proxyfactory.factory_class">NHibernate.ByteCode.LinFu.ProxyFactoryFactory, NHibernate.ByteCode.LinFu</property> <mapping resource="MyProject/Domain/User.hbm.xml"/> </session-factory> </hibernate-configuration> I created a DAO which I will use to persist domain objects to the database. The DAO uses a HibernateUtil class that creates the SessionFactory. Both classes are in the DataAccess namespace along with the Hibernate configuration. This is where the exception is occuring. Here's that class: public class HibernateUtil { private static ISessionFactory SessionFactory = BuildSessionFactory(); private static ISessionFactory BuildSessionFactory() { try { // This seems to be where the problem occurs return new Configuration().Configure().BuildSessionFactory(); } catch (TypeInitializationException ex) { Console.WriteLine("Initial SessionFactory creation failed." + ex); throw new Exception("Unable to create SessionFactory."); } } public static ISessionFactory GetSessionFactory() { return SessionFactory; } } The DataAccess namespace references the NHibernate DLLs. This is virtually the same setup I've used with Hibernate in Java, so I'm not entirely sure what I'm doing wrong here. Any ideas? Edit The innermost exception is the following: "Could not find file 'C:\Users\Tyler\Documents\Visual Studio 2010\Projects\MyProject\MyProject\ConsoleApplication\bin\Debug\hibernate.cfg.xml'." ConsoleApplication contains the entry point where I've created a User object and am trying to persist it with my DAO. Why is it looking for the configuration file there? The actual persisting takes place in the DAO, which is in DataAccess. Also, when I add the configuration file to ConsoleApplication, it still does not find it.

  • Is there a bash shortcut for traversing similar directory structures?

    - by Steve Weet
    The Korn shell used to have a very useful option to cd for traversing similar directory structures e.g. given the following directorys /home/sweet/dev/projects/trunk/projecta/app/models /home/andy/dev/projects/trunk/projecta/app/models Then if you were in the /home/sweet.... directory then you could change to the equivalent directory in andy's structure by typing cd sweet andy So if ksh saw 2 arguments then it would scan the current directory path for the first value, replace it with the second and cd there. Is anyone aware of similar functionality in bash. EDIT 1 Following on from Michal's excellent answer I have now created the following bash function called scd (For Sideways cd) function scd { cd "${PWD/$1/$2}" } EDIT 2 Thanks to @digitalross I can now reproduce the ksh functionality exactly with the code from below (With the addition of a pwd to tell you where you have changed to) cd () { if [ "x$2" != x ]; then builtin cd ${PWD/$1/$2} pwd else builtin cd "$@" fi }

  • SQL: Find difference between dates with grouping

    - by ajbeaven
    I have a problem that seems similar to this fellow - I just want to display the data slightly differently. I'm pretty terrible with SQL so can't modify it to suit, but perhaps someone else can. My table looks similar to this (date format is dd/mm/yyyy): ID User Date_start Role 1 Andy 01/04/2010 A 2 Andy 10/04/2010 B 3 Andy 20/04/2010 A 4 John 02/05/2010 A I want to show the total number of days that anyone was in a certain role. Users stay in the role until there is another entry into the table. Users can only be in one role at a time. So the summary data would look like this (assuming that the date is 04/05/2010): A: 26 days B: 10 days Thanks for any help :)

  • Exchange 2007 restore - Backup Exec Unable to Attach to a resource

    - by Andy
    I have been struggling with this one for months! Grateful for any advice. The setup is a windows 2003 server network, 4xservers on the domain. Two exchange 2007 servers (only one with mailboxes still on). Backup Exec (12.5) on a non-exchange server with agents on the others. Backup exec runs a full backup of exchange across the network well, at pretty reasonable speeds. However, when you try any kind of restore (individual emails, mailboxes or whole system restore - all to same location or to alternate server, RSG etc) the following message is received within about 10-15 secs of starting the job: Job ended: 24 December 2010 at 13:28:32 Completed status: Failed Final error: 0xe000848c - Unable to attach to a resource. Make sure that all selected resources exist and are online, and then try again. If the server or resource no longer exists, remove it from the selection list. Edit the selection list properties, click the View Selection Details tab, and then remove the resource. Final error category: Resource Errors For additional information regarding this error refer to link V-79-57344-33932 Things I have already tried: Changed account to main administrator account (with all permissions) checked versions of ese.dll on both servers - both the same Checked all VSS writers on both servers are stable / normal restoring to different locations Any advice anyone could give would be much appreciated. Many thanks, Andy

  • Error 720 on VPN (PPTP) attempt

    - by Andy Shulman
    When I attempt to connect to a server running XP x64 (so essentially Server 2003) using a PPTP connection, it fails with client-side error Registering your computer on the network... Error 720: A connection to the remote computer could not be established. You might need to change the network settings for this configuration. and server-side error Event ID: 20050 The user WINSERV3\Andy connected to port VPN8-1 has been disconnected because no network protocols were successfully negotiated. I have configured the router to pass both TCP packets on 1723 and GRE packets. I have used Wireshark (filtering out ARP, UDP, and all TCP ports other than 1723) to observe the packets received by the server. Wireshark does not explicitly name any protocol GRE, but it does tell me the server sent and received TCP, PPTP, PPP LCP, PPP CHAP, PPP CBCP, and PPP IPCP. The connection seems to go wrong at packet 30, where the protocol is PPP LCP, with the payload of the packet being labeled "Protocol Reject". Obviously, this is going from server to client. This would seem to lead to the conclusion that there is something wrong with my client, which runs Windows 7 Ultimate x64. However, it is able to connect to my house's router, which runs the DD-WRT firmware and is thus a PPTP endpoint. I'm thoroughly at a loss. Please help!

  • sendmail relay status

    - by Andy
    Hello all, I have a RHEL3 server with sendmail configured to relay mail to: # "Smart" relay host (may be null) DSmailrelay This relay server is an exchange server not administered by me. A few days ago its IP address was changed without my knowledge so I've updated the correct ip in /etc/hosts for the mail relay entry. Unfortunately no mail is currently going through and maillog reports: Oct 26 14:32:39 fsimag sendmail[12580]: n9Q3VxPA012580: from=root, size=3685, class=0, nrcpts=1, msgid=<~R.*.2009102614315955@*>, relay=root@localhost Oct 26 14:32:39 fsimag sendmail[12580]: n9Q3VxPA012580: to=wodwest@*.net, delay=00:00:40, mailer=esmtp, pri=33685, dsn=4.4.3, stat=queued Oct 26 14:36:09 fsimag sendmail[13670]: n9Q3ZTcf013670: from=root, size=5831, class=0, nrcpts=1, msgid=<~R.medicus.2009102614352914@*>, relay=root@localhost Oct 26 14:36:09 fsimag sendmail[13670]: n9Q3ZTcf013670: to=tsgastro@(.net, delay=00:00:40, mailer=esmtp, pri=35831, dsn=4.4.3, stat=queued Oct 26 14:36:50 fsimag sendmail[13882]: n9Q3aAxj013882: from=root, size=5830, class=0, nrcpts=1, msgid=<~C.medicus.2009102614361009@*>, relay=root@localhost Oct 26 14:36:50 fsimag sendmail[13882]: n9Q3aAxj013882: to=elmwood@*.net, delay=00:00:40, mailer=esmtp, pri=35830, dsn=4.4.3, stat=queued (With domains obscured) The mailq command shows nothing, and I've also tried connecting to this new mail server via telnet and manually sending and reports as being queued but not sent. The administrator of this machine has put it back to me saying he sees no problems, and I just want to cover everything before passing it back to him. Is there any other tests/logs/reasons for sendmail to only report it as "stat=queued" ? I've looked in previous logs and the relay is set to root@localhost in those but none were ever set to queued. Thanks for any help, Andy

  • Issues with creating a snapshot

    - by Andy Welcomer
    Hello everyone, We have a strange issue when attempting to create a snapshot in one of our regional environments. We have 4 VMs, 2 of them have mulitple VMDKs spread onto different datastores. When a snapshot is created, all the VMDKs (except for the first), seem to vanish. If you look at the properties of the VM, the path to the VMDKS points to the datastore where the primary VMDK is, and the file name is some random garbage. If the snapshot is deleted everything returns to normal. Has anyone ever seen this? I'm using ESX3.5 Thank you in advance. Andy ==============UPDATE============== Here is some more information. I just created a test machine with 7 VMDKs. 1 for the OS. and 6 others for data. All of the VMDKs are in seperate datastores. I take a snapshot of the machine, all of the 6 VMDKs loose their reference to the actual VMDK files. The all point to 64KB VMDK files in the datastore where the OS VMDK is located. These 64KB vmdks didn't exist until the snapshot was taken. When the snapshot is deleted, everything goes back to normal.

  • 3 Servers, is this is a cluster?

    - by Andy Barlow
    Hello, At the moment I have one Ubuntu server, 9.10, running with a simple Samba share, a mail server, DNS server and DHCP server. Mostly its just there for file sharing and email server. I also have 2 other servers that are exactly the same hardware and spec as the first, which have an rsync set up to retrieve the shared folders and backs them up. However, if the first server goes down, all of our shares disappear along with our mail and the system must be rebuilt. Also I tend to find if people are downloading a large amount from the file server, no-one can access there emails - especially in the morning when everyone is signing in at once. Would it be more beneficial for me to have all 3 servers, all running the same services, doing the same thing with some sort of cluster with load balancing? I'm not really sure where to begin looking, or how to go about such a setup where 3 servers are all identical, but perhaps one acts as the main load balancer?? If someone can point me in the right direction, or if this simply sounds like one of those Enterprise Cloud's that is now a default setup in Ubuntu Server 9.10+, then I'll go down that route. Cheers in advance. Andy

  • Kickstart CentOS 6 prompting for TCP/IP with network set to DHCP

  • Are my Linux symbolic links acting correctly?

    - by Andy Castles
    Hi all I've been using Linux on and off for the last 15 years and today I came across something in bash that surprised me. Setup the following directory structure: $ cd /tmp $ mkdir /tmp/symlinktest $ mkdir /tmp/symlinktest/dir $ mkdir /tmp/symlinktarget Now create two sym links in symlinktest pointing to symlinktarget: $ cd /tmp/symlinktest $ ln -s ../symlinktarget Asym $ ln -s ../symlinktarget Bsym Now, in bash, the following tab completion does strange things. Type the following: $ cd dir $ cd ../A[TAB] Pressing the tab key above completes the line to: $ cd ../Asym/ as I expected. Now press enter to change into Asym and type: $ cd ../B[TAB] This time pressing the tab key completes the link to: $ cd ../Bsym[space] Note that there is now a space after the Bsym and there is no trailing slash. My question is, why when changing from the physical directory "dir" to Asym it recognises that Asym is a link to a directory, but when changing from one sym link to another, it doesn't recognise that it's a link to a directory? In addition, if I try to create a new file within Asym, I get an error message: $ cd /tmp/symlinktest/Asym $ cat hello > ../Bsym/file.txt -bash: ../Bsym/file.txt: No such file or directory I always thought that symlinks were mostly transparent except to programs that need to manipulate them. Is this normal behaviour? Many thanks, Andy

  • Walk me through the Linux log files (please)

    - by Andy
    Hey all, I just tried loading a 2MB file in gedit and it silently died on me. I was wondering if anything might appear in a log file that might help me diagnose this: I checked syslog and found out it segfaulted. While doing this I realised that I don't really know anything about how logging is organised on *nix machines. All I know at the mo is Logs are typically stored in /var/log/... is there anywhere else that I should know about? I'm familiar with application specific logs, such as apache's. I understand that dmesg is the bootup log, and syslog is a general system log... is that right? So would someone mind taking me through the most useful logs? Are the two logs I mention in the final point the only general logs? And what are the funky numbers at the start of lines in dmesg? Seconds since startup? Please include anything in your answers that you think would improve my understanding here and help me track down anomalies! TIA Andy

  • Oracle VDI Seminar - June-30

    - by mprove
    More from Andy Hall about Oracle VDI:  Oracle Virtual Desktop Infrastructure allows you to bring your desktop environments under control by hosting and managing them centrally in the data center. Users then connect to their desktops over the network using their existing PCs and simple client software, or with Oracle's Sun Ray Clients. Virtual desktops provide a number of benefits, including:  Cost reductions by allowing global or local changes and updates to the desktop environment from a centralized management location.  Better security by keeping sensitive data off of individual computers and retaining it safely in the data center.  Improved availability and business continuity because workers can access their desktops from nearly anywhere.  Join us to get the latest updates on Oracle Virtual Desktop Infrastructure and learn how moving to a virtualized desktop environment can help your organization, today and into the future.  Speaker:  Andy Hall - Virtual Desktop Infrastructure Product Management, Oracle Event Date: 06/30/2011 09:00 AM Pacific Daylight Time Register here_

  • How can I centralise MySQL data between 3 or more geographically separate servers?

    - by Andy Castles
    To explain the background to the question: We have a home-grown PHP application (for running online language-learning courses) running on a Linux server and using MySQL on localhost for saving user data (e.g. results of tests taken, marks of submitted work, time spent on different pages in the courses, etc). As we have students from different geographic locations we currently have 3 virtual servers hosted close to those locations (Spain, UK and Hong Kong) and users are added to the server closest to them (they access via different URLs, e.g. europe.domain.com, uk.domain.com and asia.domain.com). This works but is an administrative nightmare as we have to remember which server a particular user is on, and users can only connect to one server. We would like to somehow centralise the information so that all users are visible on any of the servers and users could connect to any of the 3 servers. The question is, what method should we use to implement this. It must be an issue that that lots of people have encountered but I haven't found anything conclusive after a fair bit of Googling around. The closest I have seen to solutions are: something like master-master replication, but I have read so many posts suggesting that this is not a good idea as things like auto_increment fields can break. circular replication, this sounded perfect but to quote from O'Reilly's High Performance MySQL, "In general, rings are brittle and best avoided" We're not against rewriting code in the application to make it work with whatever solution is required but I am not sure if replication is the correct thing to use. Thanks, Andy P.S. I should add that we experimented with writes to a central database and then using reads from a local database but the response time between the different servers for writing was pretty bad and it's also important that written data is available immediately for reading so if replication is too slow this could cause out-of-date data to be returned. Edit: I have been thinking about writing my own rudimentary replication script which would involve something like having each user given a server ID to say which is his "home server", e.g. users in asia would be marked as having the Hong Kong server as their own server. Then the replication scripts (which would be a PHP script set to run as a cron job reasonably frequently, e.g. every 15 minutes or so) would run independently on each of the servers in the system. They would go through the database and distribute any information about users with the "home server" set to the server that the script is running on to all of the other databases in the system. They would also need to suck new information which has been added to any of the other databases on the system where the "home server" flag is the server where the script is running. I would need to work out the details and build in the logic to deal with conflicts but I think it would be possible, however I wanted to make sure that there is not a correct solution for this already out there as it seems like it must be a problem that many people have already come across.
