Varnish VCL Reload Fails After Adding Second Backend

- by Andy

I have been running Varnish on my production server successfully for several weeks now. Now I'm trying to configure Varnish to use a second backend for certain requests. My original working VCL (/etc/varnish/default.vcl) begins like this: backend default { .host = "127.0.0.1"; .port = "8080"; } ...rest of VCL... And I'm changing it to: backend default { .host = "127.0.0.1"; .port = "8080"; } backend backend2 { .host = "12.34.56.78"; .port = "80"; } ...rest of VCL... When I reload the VCL file, I get the following: Command failed with error code 106 Failed to reload /etc/varnish/default.vcl. Any idea what the error could be, or how I can get more information on the problem?

iptables not allowing mysql connections to aliased ips?

- by Curtis

I have a fairly simple iptables firewall on a server that provides MySQL services, but iptables seems to be giving me very inconsistent results. The default policy on the script is as follows: iptables -P INPUT DROP I can then make MySQL public with the following rule: iptables -A INPUT -p tcp --dport 3306 -j ACCEPT With this rule in place, I can connect to MySQL from any source IP to any destination IP on the server without a problem. However, when I try to restrict access to just three IPs by replacing the above line with the following, I run into trouble (xxx=masked octect): iptables -A INPUT -p tcp --dport 3306 -m state --state NEW -s 208.XXX.XXX.184 -j ACCEPT iptables -A INPUT -p tcp --dport 3306 -m state --state NEW -s 208.XXX.XXX.196 -j ACCEPT iptables -A INPUT -p tcp --dport 3306 -m state --state NEW -s 208.XXX.XXX.251 -j ACCEPT Once the above rules are in place, the following happens: I can connect to the MySQL server from the .184, .196 and .251 hosts just fine as long as am connecting to the MySQL server using it's default IP address or an IP alias in the same subnet as the default IP address. I am unable to connect to MySQL using IP aliases that are assigned to the server from a different subnet than the server's default IP when I'm coming from the .184 or .196 hosts, but .251 works just fine. From the .184 or .196 hosts, a telnet attempt just hangs... # telnet 209.xxx.xxx.22 3306 Trying 209.xxx.xxx.22... If I remove the .251 line (making .196 the last rule added), the .196 host still can not connect to MySQL using IP aliases (so it's not the order of the rules that is causing the inconsistent behavior). I know, this particular test was silly as it shouldn't matter what order these three rules are added in, but I figured someone might ask. If I switch back to the "public" rule, all hosts can connect to the MySQL server using either the default or aliased IPs (in either subnet): iptables -A INPUT -p tcp --dport 3306 -j ACCEPT The server is running in a CentOS 5.4 OpenVZ/Proxmox container (2.6.32-4-pve). And, just in case you prefer to see the problem rules in the context of the iptables script, here it is (xxx=masked octect): # Flush old rules, old custom tables /sbin/iptables --flush /sbin/iptables --delete-chain # Set default policies for all three default chains /sbin/iptables -P INPUT DROP /sbin/iptables -P FORWARD DROP /sbin/iptables -P OUTPUT ACCEPT # Enable free use of loopback interfaces /sbin/iptables -A INPUT -i lo -j ACCEPT /sbin/iptables -A OUTPUT -o lo -j ACCEPT # All TCP sessions should begin with SYN /sbin/iptables -A INPUT -p tcp ! --syn -m state --state NEW -j DROP # Accept inbound TCP packets (Do this *before* adding the 'blocked' chain) /sbin/iptables -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT # Allow the server's own IP to connect to itself /sbin/iptables -A INPUT -i eth0 -s 208.xxx.xxx.178 -j ACCEPT # Add the 'blocked' chain *after* we've accepted established/related connections # so we remain efficient and only evaluate new/inbound connections /sbin/iptables -N BLOCKED /sbin/iptables -A INPUT -j BLOCKED # Accept inbound ICMP messages /sbin/iptables -A INPUT -p ICMP --icmp-type 8 -j ACCEPT /sbin/iptables -A INPUT -p ICMP --icmp-type 11 -j ACCEPT # ssh (private) /sbin/iptables -A INPUT -p tcp --dport 22 -m state --state NEW -s xxx.xxx.xxx.xxx -j ACCEPT # ftp (private) /sbin/iptables -A INPUT -p tcp --dport 21 -m state --state NEW -s xxx.xxx.xxx.xxx -j ACCEPT # www (public) /sbin/iptables -A INPUT -p tcp --dport 80 -j ACCEPT /sbin/iptables -A INPUT -p tcp --dport 443 -j ACCEPT # smtp (public) /sbin/iptables -A INPUT -p tcp --dport 25 -j ACCEPT /sbin/iptables -A INPUT -p tcp --dport 2525 -j ACCEPT # pop (public) /sbin/iptables -A INPUT -p tcp --dport 110 -j ACCEPT # mysql (private) /sbin/iptables -A INPUT -p tcp --dport 3306 -m state --state NEW -s 208.xxx.xxx.184 -j ACCEPT /sbin/iptables -A INPUT -p tcp --dport 3306 -m state --state NEW -s 208.xxx.xxx.196 -j ACCEPT /sbin/iptables -A INPUT -p tcp --dport 3306 -m state --state NEW -s 208.xxx.xxx.251 -j ACCEPT Any ideas? Thanks in advance. :-)

Option Trading: Getting the most out of the event session options

- by extended_events

You can control different aspects of how an event session behaves by setting the event session options as part of the CREATE EVENT SESSION DDL. The default settings for the event session options are designed to handle most of the common event collection situations so I generally recommend that you just use the defaults. Like everything in the real world though, there are going to be a handful of “special cases” that require something different. This post focuses on identifying the special cases and the correct use of the options to accommodate those cases. There is a reason it’s called Default The default session options specify a total event buffer size of 4 MB with a 30 second latency. Translating this into human terms; this means that our default behavior is that the system will start processing events from the event buffer when we reach about 1.3 MB of events or after 30 seconds, which ever comes first. Aside: What’s up with the 1.3 MB, I thought you said the buffer was 4 MB?The Extended Events engine takes the total buffer size specified by MAX_MEMORY (4MB by default) and divides it into 3 equally sized buffers. This is done so that a session can be publishing events to one buffer while other buffers are being processed. There are always at least three buffers; how to get more than three is covered later. Using this configuration, the Extended Events engine can “keep up” with most event sessions on standard workloads. Why is this? The fact is that most events are small, really small; on the order of a couple hundred bytes. Even when you start considering events that carry dynamically sized data (eg. binary, text, etc.) or adding actions that collect additional data, the total size of the event is still likely to be pretty small. This means that each buffer can likely hold thousands of events before it has to be processed. When the event buffers are finally processed there is an economy of scale achieved since most targets support bulk processing of the events so they are processed at the buffer level rather than the individual event level. When all this is working together it’s more likely that a full buffer will be processed and put back into the ready queue before the remaining buffers (remember, there are at least three) are full. I know what you’re going to say: “My server is exceptional! My workload is so massive it defies categorization!” OK, maybe you weren’t going to say that exactly, but you were probably thinking it. The point is that there are situations that won’t be covered by the Default, but that’s a good place to start and this post assumes you’ve started there so that you have something to look at in order to determine if you do have a special case that needs different settings. So let’s get to the special cases… What event just fired?! How about now?! Now?! If you believe the commercial adage from Heinz Ketchup (Heinz Slow Good Ketchup ad on You Tube), some things are worth the wait. This is not a belief held by most DBAs, particularly DBAs who are looking for an answer to a troubleshooting question fast. If you’re one of these anxious DBAs, or maybe just a Program Manager doing a demo, then 30 seconds might be longer than you’re comfortable waiting. If you find yourself in this situation then consider changing the MAX_DISPATCH_LATENCY option for your event session. This option will force the event buffers to be processed based on your time schedule. This option only makes sense for the asynchronous targets since those are the ones where we allow events to build up in the event buffer – if you’re using one of the synchronous targets this option isn’t relevant. Avoid forgotten events by increasing your memory Have you ever had one of those days where you keep forgetting things? That can happen in Extended Events too; we call it dropped events. In order to optimizes for server performance and help ensure that the Extended Events doesn’t block the server if to drop events that can’t be published to a buffer because the buffer is full. You can determine if events are being dropped from a session by querying the dm_xe_sessions DMV and looking at the dropped_event_count field. Aside: Should you care if you’re dropping events?Maybe not – think about why you’re collecting data in the first place and whether you’re really going to miss a few dropped events. For example, if you’re collecting query duration stats over thousands of executions of a query it won’t make a huge difference to miss a couple executions. Use your best judgment. If you find that your session is dropping events it means that the event buffer is not large enough to handle the volume of events that are being published. There are two ways to address this problem. First, you could collect fewer events – examine you session to see if you are over collecting. Do you need all the actions you’ve specified? Could you apply a predicate to be more specific about when you fire the event? Assuming the session is defined correctly, the next option is to change the MAX_MEMORY option to a larger number. Picking the right event buffer size might take some trial and error, but a good place to start is with the number of dropped events compared to the number you’ve collected. Aside: There are three different behaviors for dropping events that you specify using the EVENT_RETENTION_MODE option. The default is to allow single event loss and you should stick with this setting since it is the best choice for keeping the impact on server performance low.You’ll be tempted to use the setting to not lose any events (NO_EVENT_LOSS) – resist this urge since it can result in blocking on the server. If you’re worried that you’re losing events you should be increasing your event buffer memory as described in this section. Some events are too big to fail A less common reason for dropping an event is when an event is so large that it can’t fit into the event buffer. Even though most events are going to be small, you might find a condition that occasionally generates a very large event. You can determine if your session is dropping large events by looking at the dm_xe_sessions DMV once again, this time check the largest_event_dropped_size. If this value is larger than the size of your event buffer [remember, the size of your event buffer, by default, is max_memory / 3] then you need a large event buffer. To specify a large event buffer you set the MAX_EVENT_SIZE option to a value large enough to fit the largest event dropped based on data from the DMV. When you set this option the Extended Events engine will create two buffers of this size to accommodate these large events. As an added bonus (no extra charge) the large event buffer will also be used to store normal events in the cases where the normal event buffers are all full and waiting to be processed. (Note: This is just a side-effect, not the intended use. If you’re dropping many normal events then you should increase your normal event buffer size.) Partitioning: moving your events to a sub-division Earlier I alluded to the fact that you can configure your event session to use more than the standard three event buffers – this is called partitioning and is controlled by the MEMORY_PARTITION_MODE option. The result of setting this option is fairly easy to explain, but knowing when to use it is a bit more art than science. First the science… You can configure partitioning in three ways: None, Per NUMA Node & Per CPU. This specifies the location where sets of event buffers are created with fairly obvious implication. There are rules we follow for sub-dividing the total memory (specified by MAX_MEMORY) between all the event buffers that are specific to the mode used: None: 3 buffers (fixed)Node: 3 * number_of_nodesCPU: 2.5 * number_of_cpus Here are some examples of what this means for different Node/CPU counts: Configuration None Node CPU 2 CPUs, 1 Node 3 buffers 3 buffers 5 buffers 6 CPUs, 2 Node 3 buffers 6 buffers 15 buffers 40 CPUs, 5 Nodes 3 buffers 15 buffers 100 buffers Aside: Buffer size on multi-processor computersAs the number of Nodes or CPUs increases, the size of the event buffer gets smaller because the total memory is sub-divided into more pieces. The defaults will hold up to this for a while since each buffer set is holding events only from the Node or CPU that it is associated with, but at some point the buffers will get too small and you’ll either see events being dropped or you’ll get an error when you create your session because you’re below the minimum buffer size. Increase the MAX_MEMORY setting to an appropriate number for the configuration. The most likely reason to start partitioning is going to be related to performance. If you notice that running an event session is impacting the performance of your server beyond a reasonably expected level [Yes, there is a reasonably expected level of work required to collect events.] then partitioning might be an answer. Before you partition you might want to check a few other things: Is your event retention set to NO_EVENT_LOSS and causing blocking? (I told you not to do this.) Consider changing your event loss mode or increasing memory. Are you over collecting and causing more work than necessary? Consider adding predicates to events or removing unnecessary events and actions from your session. Are you writing the file target to the same slow disk that you use for TempDB and your other high activity databases? <kidding> <not really> It’s always worth considering the end to end picture – if you’re writing events to a file you can be impacted by I/O, network; all the usual stuff. Assuming you’ve ruled out the obvious (and not so obvious) issues, there are performance conditions that will be addressed by partitioning. For example, it’s possible to have a successful event session (eg. no dropped events) but still see a performance impact because you have many CPUs all attempting to write to the same free buffer and having to wait in line to finish their work. This is a case where partitioning would relieve the contention between the different CPUs and likely reduce the performance impact cause by the event session. There is no DMV you can check to find these conditions – sorry – that’s where the art comes in. This is largely a matter of experimentation. On the bright side you probably won’t need to to worry about this level of detail all that often. The performance impact of Extended Events is significantly lower than what you may be used to with SQL Trace. You will likely only care about the impact if you are trying to set up a long running event session that will be part of your everyday workload – sessions used for short term troubleshooting will likely fall into the “reasonably expected impact” category. Hey buddy – I think you forgot something OK, there are two options I didn’t cover: STARTUP_STATE & TRACK_CAUSALITY. If you want your event sessions to start automatically when the server starts, set the STARTUP_STATE option to ON. (Now there is only one option I didn’t cover.) I’m going to leave causality for another post since it’s not really related to session behavior, it’s more about event analysis. - Mike Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!

Demystifying Silverlight Dependency Properties

- by dwahlin

I have the opportunity to teach a lot of people about Silverlight (amongst other technologies) and one of the topics that definitely confuses people initially is the concept of dependency properties. I confess that when I first heard about them my initial thought was “Why do we need a specialized type of property?” While you can certainly use standard CLR properties in Silverlight applications, Silverlight relies heavily on dependency properties for just about everything it does behind the scenes. In fact, dependency properties are an essential part of the data binding, template, style and animation functionality available in Silverlight. They simply back standard CLR properties. In this post I wanted to put together a (hopefully) simple explanation of dependency properties and why you should care about them if you’re currently working with Silverlight or looking to move to it. What are Dependency Properties? XAML provides a great way to define layout controls, user input controls, shapes, colors and data binding expressions in a declarative manner. There’s a lot that goes on behind the scenes in order to make XAML work and an important part of that magic is the use of dependency properties. If you want to bind data to a property, style it, animate it or transform it in XAML then the property involved has to be a dependency property to work properly. If you’ve ever positioned a control in a Canvas using Canvas.Left or placed a control in a specific Grid row using Grid.Row then you’ve used an attached property which is a specialized type of dependency property. Dependency properties play a key role in XAML and the overall Silverlight framework. Any property that you bind, style, template, animate or transform must be a dependency property in Silverlight applications. You can programmatically bind values to controls and work with standard CLR properties, but if you want to use the built-in binding expressions available in XAML (one of my favorite features) or the Binding class available through code then dependency properties are a necessity. Dependency properties aren’t needed in every situation, but if you want to customize your application very much you’ll eventually end up needing them. For example, if you create a custom user control and want to expose a property that consumers can use to change the background color, you have to define it as a dependency property if you want bindings, styles and other features to be available for use. Now that the overall purpose of dependency properties has been discussed let’s take a look at how you can create them. Creating Dependency Properties When .NET first came out you had to write backing fields for each property that you defined as shown next: Brush _ScheduleBackground; public Brush ScheduleBackground { get { return _ScheduleBackground; } set { _ScheduleBackground = value; } } Although .NET 2.0 added auto-implemented properties (for example: public Brush ScheduleBackground { get; set; }) where the compiler would automatically generate the backing field used by get and set blocks, the concept is still the same as shown in the above code; a property acts as a wrapper around a field. Silverlight dependency properties replace the _ScheduleBackground field shown in the previous code and act as the backing store for a standard CLR property. The following code shows an example of defining a dependency property named ScheduleBackgroundProperty: public static readonly DependencyProperty ScheduleBackgroundProperty = DependencyProperty.Register("ScheduleBackground", typeof(Brush), typeof(Scheduler), null); Looking through the code the first thing that may stand out is that the definition for ScheduleBackgroundProperty is marked as static and readonly and that the property appears to be of type DependencyProperty. This is a standard pattern that you’ll use when working with dependency properties. You’ll also notice that the property explicitly adds the word “Property” to the name which is another standard you’ll see followed. In addition to defining the property, the code also makes a call to the static DependencyProperty.Register method and passes the name of the property to register (ScheduleBackground in this case) as a string. The type of the property, the type of the class that owns the property and a null value (more on the null value later) are also passed. In this example a class named Scheduler acts as the owner. The code handles registering the property as a dependency property with the call to Register(), but there’s a little more work that has to be done to allow a value to be assigned to and retrieved from the dependency property. The following code shows the complete code that you’ll typically use when creating a dependency property. You can find code snippets that greatly simplify the process of creating dependency properties out on the web. The MVVM Light download available from http://mvvmlight.codeplex.com comes with built-in dependency properties snippets as well. public static readonly DependencyProperty ScheduleBackgroundProperty = DependencyProperty.Register("ScheduleBackground", typeof(Brush), typeof(Scheduler), null); public Brush ScheduleBackground { get { return (Brush)GetValue(ScheduleBackgroundProperty); } set { SetValue(ScheduleBackgroundProperty, value); } } The standard CLR property code shown above should look familiar since it simply wraps the dependency property. However, you’ll notice that the get and set blocks call GetValue and SetValue methods respectively to perform the appropriate operation on the dependency property. GetValue and SetValue are members of the DependencyObject class which is another key component of the Silverlight framework. Silverlight controls and classes (TextBox, UserControl, CompositeTransform, DataGrid, etc.) ultimately derive from DependencyObject in their inheritance hierarchy so that they can support dependency properties. Dependency properties defined in Silverlight controls and other classes tend to follow the pattern of registering the property by calling Register() and then wrapping the dependency property in a standard CLR property (as shown above). They have a standard property that wraps a registered dependency property and allows a value to be assigned and retrieved. If you need to expose a new property on a custom control that supports data binding expressions in XAML then you’ll follow this same pattern. Dependency properties are extremely useful once you understand why they’re needed and how they’re defined. Detecting Changes and Setting Defaults When working with dependency properties there will be times when you want to assign a default value or detect when a property changes so that you can keep the user interface in-sync with the property value. Silverlight’s DependencyProperty.Register() method provides a fourth parameter that accepts a PropertyMetadata object instance. PropertyMetadata can be used to hook a callback method to a dependency property. The callback method is called when the property value changes. PropertyMetadata can also be used to assign a default value to the dependency property. By assigning a value of null for the final parameter passed to Register() you’re telling the property that you don’t care about any changes and don’t have a default value to apply. Here are the different constructor overloads available on the PropertyMetadata class: PropertyMetadata Constructor Overload Description PropertyMetadata(Object) Used to assign a default value to a dependency property. PropertyMetadata(PropertyChangedCallback) Used to assign a property changed callback method. PropertyMetadata(Object, PropertyChangedCalback) Used to assign a default property value and a property changed callback. There are many situations where you need to know when a dependency property changes or where you want to apply a default. Performing either task is easily accomplished by creating a new instance of the PropertyMetadata class and passing the appropriate values to its constructor. The following code shows an enhanced version of the initial dependency property code shown earlier that demonstrates these concepts: public Brush ScheduleBackground { get { return (Brush)GetValue(ScheduleBackgroundProperty); } set { SetValue(ScheduleBackgroundProperty, value); } } public static readonly DependencyProperty ScheduleBackgroundProperty = DependencyProperty.Register("ScheduleBackground", typeof(Brush), typeof(Scheduler), new PropertyMetadata(new SolidColorBrush(Colors.LightGray), ScheduleBackgroundChanged)); private static void ScheduleBackgroundChanged(DependencyObject d, DependencyPropertyChangedEventArgs e) { var scheduler = d as Scheduler; scheduler.Background = e.NewValue as Brush; } The code wires ScheduleBackgroundProperty to a property change callback method named ScheduleBackgroundChanged. What’s interesting is that this callback method is static (as is the dependency property) so it gets passed the instance of the object that owns the property that has changed (otherwise we wouldn’t be able to get to the object instance). In this example the dependency object is cast to a Scheduler object and its Background property is assigned to the new value of the dependency property. The code also handles assigning a default value of LightGray to the dependency property by creating a new instance of a SolidColorBrush. To Sum Up In this post you’ve seen the role of dependency properties and how they can be defined in code. They play a big role in XAML and the overall Silverlight framework. You can think of dependency properties as being replacements for fields that you’d normally use with standard CLR properties. In addition to a discussion on how dependency properties are created, you also saw how to use the PropertyMetadata class to define default dependency property values and hook a dependency property to a callback method. The most important thing to understand with dependency properties (especially if you’re new to Silverlight) is that they’re needed if you want a property to support data binding, animations, transformations and styles properly. Any time you create a property on a custom control or user control that has these types of requirements you’ll want to pick a dependency property over of a standard CLR property with a backing field. There’s more that can be covered with dependency properties including a related property called an attached property….more to come.

Thunderbird compact is taking forever

- by mulllhausen

One day I came in to work and found that our development server - a Ubuntu box had a full hard disk. I did a bit of investigation using the du command and it seems like mozilla thunderbird is the major culprit. After burning off some backups, the disk was left at 94%: $ df -h Filesystem Size Used Avail Use% Mounted on /dev/sda1 895G 791G 59G 94% / none 4.0G 300K 4.0G 1% /dev none 4.0G 1.4M 4.0G 1% /dev/shm none 4.0G 140K 4.0G 1% /var/run none 4.0G 0 4.0G 0% /var/lock none 4.0G 0 4.0G 0% /lib/init/rw $ cd $ du -ch | grep [0-9]G 666G ./.thunderbird/ccsmcruu.default/ImapMail/mail.adofms.com.au 666G ./.thunderbird/ccsmcruu.default/ImapMail 667G ./.thunderbird/ccsmcruu.default 667G ./.thunderbird 2.2G ./.VirtualBox/Machines/iBike/Snapshots 2.2G ./.VirtualBox/Machines/iBike 2.2G ./.VirtualBox/Machines 2.2G ./.VirtualBox 670G . 670G total I did some reading and found that Mozilla Thunderbird does not compact files by default - i.e. all of the old emails that were sent to trash are still kept. One of the mailboxes used to get a lot of spam so I guess this accounts for the 667GB. I opened up Thunderbird to see how much space the inbox actually takes up and it turns out to be approximately 500MB - over 1000 times less than the stuff that has not been compacted over the years. So i right clicked on the inbox directory in the tree on the left of Thunderbird and selected 'compact'. I left it for about 12hours but even after that it still said 'compacting folder' on the status bar. I don't use Thunderbird on this PC - it belonged to a colleague who has left the company, however I do occasionally need to look through the inbox for references to the project I am working on, so deleting all traces of Thunderbird is not an option. My question is - is there any way I can monitor the progress of Thunderbird's compacting function? I would really like to know how long it is going to take. Also is there any way I can speed up the compacting process?

Drupal install and permissions

- by Richard

So I'm really stuck on this issue. An install process is complaining about write permission on settings.php and sites/default/files/. However, I've moved these files temporarily to write/read (chmod 777) and changed the owner/group to "apache" as shown below. -bash-4.1$ ls -hal total 28K drwxrwxrwx. 3 richard richard 4.0K Aug 23 15:03 . drwxr-xr-x. 4 richard richard 4.0K Aug 18 14:20 .. -rwxrwxrwx. 1 apache apache 9.3K Mar 23 16:34 default.settings.php drwxrwxrwx. 2 apache apache 4.0K Aug 23 15:03 files -rwxrwxrwx. 1 apache apache 0 Aug 23 15:03 settings.php However, the install is still complaining about write permissions. I followed steps one and two of the INSTALL.txt but no luck. Update: To further explore the situation, I created sites/default/richard.php with the following code: <?php error_reporting(E_ALL); ini_set('display_errors', '1'); mkdir('files'); print("<hr> User is "); passthru("whoami"); passthru("pwd"); ?> Run from the command line (under user "richard"), no problem. The folder is created everything is a go.

Nginx as a proxy to Jetty

- by user36812

Pardon me, this is my first attempt at Nginx-Jetty instead of Apache-JK-Tomcat. I deployed myapp.war file to $JETTY_HOME/webapps/, and the app is accessible at the url: http://myIP:8080/myapp I did a default installation of Nginx, and the default Nginx page is accessible at myIP Then, I modified the default domain under /etc/nginx/sites-enabled to the following: server { listen 80; server_name mydomain.com; access_log /var/log/nginx/localhost.access.log; location / { #root /var/www/nginx-default; #index index.html index.htm; proxy_pass http://127.0.0.1:8080/myapp/; } error_page 500 502 503 504 /50x.html; location = /50x.html { root /var/www/nginx-default; } } Now I get the index page of mypp (running in jetty) when I hit myIP, which is good. But all the links are malformed. eg. The link to css is mydomain.com/myapp/css/style.css while what it should have been is mydomain.com/css/style.css. It seems to be mapping mydomain.com to 127.0.0.1:8080 instead of 127.0.0.1:8080/myapp/ Any idea what am missing? Do I need to change anything on the Jetty side too?

Move Firefox’s Tab Bar to the Top

- by Asian Angel

Would you prefer to have Firefox’s Tab Bar located at the top of the browser instead of its’ default location? See how easy it is to move the Tab Bar back and forth between the top and current positions “flip switch style” with the Tabs On Top extension. Note: Tabs On Top extension supports multi-row feature in TabMixPlus. Before You can see the “Tab Bar” in its’ default location here in our test browser…not bad but what if you prefer having it located at the top of the browser? After As soon as you have installed the extension and restarted Firefox the “Tab Bar” will have automatically moved to the top of the browser. You will most likely notice a slight decrease in tab height as well (which occurred during our tests). To move the “Tab Bar” back and forth between the top and default locations just select/deselect “Tab Bar on top” in the “Toolbars Context Menu”. You can quickly reduce the size of the upper UI after hiding some of the other toolbars and go even further if you like using extensions that will hide the “Title Bar”.

PAM Winbind Expired Password

- by kernelpanic

We've got Winbind/Kerberos setup on RHEL for AD authentication. Working fine however I noticed that when a password has expired, we get a warning but shell access is still granted. What's the proper way of handling this? Can we tell PAM to close the session once it sees the password has expired? Example: login as: ad-user [email protected]'s password: Warning: password has expired. [ad-user@server ~]$ Contents of /etc/pam.d/system-auth: auth required pam_env.so auth sufficient pam_unix.so nullok try_first_pass auth requisite pam_succeed_if.so uid >= 500 quiet auth sufficient pam_krb5.so use_first_pass auth sufficient pam_winbind.so use_first_pass auth required pam_deny.so account [default=2 success=ignore] pam_succeed_if.so quiet uid >= 10000000 account sufficient pam_succeed_if.so user ingroup AD_Admins debug account requisite pam_succeed_if.so user ingroup AD_Developers debug account required pam_access.so account required pam_unix.so broken_shadow account sufficient pam_localuser.so account sufficient pam_succeed_if.so uid < 500 quiet account [default=bad success=ok user_unknown=ignore] pam_krb5.so account [default=bad success=ok user_unknown=ignore] pam_winbind.so account required pam_permit.so password requisite pam_cracklib.so try_first_pass retry=3 password sufficient pam_unix.so md5 shadow nullok try_first_pass use_authtok password sufficient pam_krb5.so use_authtok password sufficient pam_winbind.so use_authtok password required pam_deny.so session [default=2 success=ignore] pam_succeed_if.so quiet uid >= 10000000 session sufficient pam_succeed_if.so user ingroup AD_Admins debug session requisite pam_succeed_if.so user ingroup AD_Developers debug session optional pam_mkhomedir.so umask=0077 skel=/etc/skel session optional pam_keyinit.so revoke session required pam_limits.so session optional pam_mkhomedir.so session [success=1 default=ignore] pam_succeed_if.so service in crond quiet use_uid session required pam_unix.so session optional pam_krb5.so

Using the JRockit Flight Recorder as an In-Flight Black Box

- by Marcus Hirt

The new JRockit Flight Recorder has some very interesting properties. It can be used like the black box of an airplane, allowing users to go back in time and check what was happening around the time when something went wrong. Here is how to enable the default continuous recording in JRockit to allow for that use case. The flight recorder is on by default in JRockit R28, the problem is that there is no recording running by default. To configure JRockit to start with the default recording running, add the parameter: -XX:FlightRecorderOptions=defaultrecording=true That will enable a recording with recording ID 0. You can see that it has been started properly by choosing Show Recordings from the context menu in JRockit Mission Control. You should see something similar to the picture below. Simply right click on the recording and select dump to dump information available in the flight recorder. You can select to dump data for a specific period of time or all data. For more information about the command line parameters available to control the Flight Recorder, see the JRockit documentation.

mysql startup, shtudown and logging on osx

- by Joelio

Hi, I am trying to troubleshoot some mysql problems (I have a table I cant seem to delete or drop, it hangs forever) I have 10.5.8 osx, I dont remember how/if I installed mysql, here is what I know: it automatically starts on boot the process looks like this: /usr/local/mysql/libexec/mysqld --basedir=/usr/local/mysql --datadir=/usr/local/mysql/var --pid-file=/usr/local/mysql/var/Joels-New-Pro.local.pid _mysql 96 0.0 0.0 75884 684 ?? Ss Sat06PM 0:00.02 /bin/sh /usr/local/mysql/bin/mysqld_safe when I run: /usr/local/mysql/libexec/mysqld --verbose --help it says: /usr/local/mysql/libexec/mysqld Ver 5.0.45 for apple-darwin9.1.0 on i686 (Source distribution) it seems to use my.cnf from /etc/my.cnf Now here are my questions: I dont see anything in the startupitems that remotely looks like mysql ls /Library/StartupItems/ BRESINKx86Monitoring ChmodBPF HP IO HP Trap Monitor Parallels ParallelsTransporter 1.) So how does it startup automatically? 2.) How do I start & stop this type of installation? Also, looking at the config, the logs have no values: /usr/local/mysql/libexec/mysqld --verbose --help|grep '^log' log (No default value) log-bin (No default value) log-bin-index (No default value) log-bin-trust-function-creators FALSE log-bin-trust-routine-creators FALSE log-error log-isam myisam.log log-queries-not-using-indexes FALSE log-short-format FALSE log-slave-updates FALSE log-slow-admin-statements FALSE log-slow-queries (No default value) log-tc tc.log log-tc-size 24576 log-update (No default value) log-warnings 1 3.) Does that mean there is no logging enabled in mysetup? thanks in advance! Joel

Change sysout logging level for Weblogic

- by Justin Voss

When I run a local copy of Weblogic, I like to see the output in the console so that I can observe my app's logging messages. But, Weblogic spits out a lot of log messages I don't care about, like these: [ACTIVE] ExecuteThread: '0' for queue: 'weblogic.kernel.Default (self-tuning)' 08-29-2010 01:02:21 INFO Getting a JNDI connection [ACTIVE] ExecuteThread: '0' for queue: 'weblogic.kernel.Default (self-tuning)' 08-29-2010 01:02:21 INFO Connection Returned. Elapsed time to acquire=0ms. [ACTIVE] ExecuteThread: '0' for queue: 'weblogic.kernel.Default (self-tuning)' 08-29-2010 01:02:21 INFO Getting a JNDI connection [ACTIVE] ExecuteThread: '0' for queue: 'weblogic.kernel.Default (self-tuning)' 08-29-2010 01:02:21 INFO Connection Returned. Elapsed time to acquire=0ms. Can I configure Weblogic to not output those? I assume that I can change the logging level to something higher than INFO and that should fix it?

Drupal install and permissions

- by Richard

So I'm really stuck on this issue. An install process is complaining about write permission on settings.php and sites/default/files/. However, I've moved these files temporarily to write/read (chmod 777) and changed the owner/group to "apache" as shown below. -bash-4.1$ ls -hal total 28K drwxrwxrwx. 3 richard richard 4.0K Aug 23 15:03 . drwxr-xr-x. 4 richard richard 4.0K Aug 18 14:20 .. -rwxrwxrwx. 1 apache apache 9.3K Mar 23 16:34 default.settings.php drwxrwxrwx. 2 apache apache 4.0K Aug 23 15:03 files -rwxrwxrwx. 1 apache apache 0 Aug 23 15:03 settings.php However, the install is still complaining about write permissions. I followed steps one and two of the INSTALL.txt but no luck. Update: To further explore the situation, I created sites/default/richard.php with the following code: <?php error_reporting(E_ALL); ini_set('display_errors', '1'); mkdir('files'); print("<hr> User is "); passthru("whoami"); passthru("pwd"); ?> Run from the command line (under user "richard"), no problem. The folder is created everything is a go. Run from the web, I get the following: Warning: mkdir(): Permission denied in /var/www/html/sites/default/richard.php on line 9 User is apache /var/www/html/sites/default Update 2: Safe mode appears to be off... -bash-4.1$ cat /etc/php.ini | grep safe | grep mode | grep -v \; safe_mode = Off safe_mode_gid = Off safe_mode_include_dir = safe_mode_exec_dir = safe_mode_allowed_env_vars = PHP_ safe_mode_protected_env_vars = LD_LIBRARY_PATH sql.safe_mode = Off

Inbound SIP calls through Cisco 881 NAT hang up after a few seconds

- by MasterRoot24

I've recently moved to a Cisco 881 router for my WAN link. I was previously using a Cisco Linksys WAG320N as my modem/router/WiFi AP/NAT firewall. The WAG320N is now running in bridged mode, so it's simply acting as a modem with one of it's LAN ports connected to FE4 WAN on my Cisco 881. The Cisco 881 get's a DHCP provided IP from my ISP. My LAN is part of default Vlan 1 (192.168.1.0/24). General internet connectivity is working great, I've managed to setup static NAT rules for my HTTP/HTTPS/SMTP/etc. services which are running on my LAN. I don't know whether it's worth mentioning that I've opted to use NVI NAT (ip nat enable as opposed to the traditional ip nat outside/ip nat inside) setup. My reason for this is that NVI allows NAT loopback from my LAN to the WAN IP and back in to the necessary server on the LAN. I run an Asterisk 1.8 PBX on my LAN, which connects to a SIP provider on the internet. Both inbound and outbound calls through the old setup (WAG320N providing routing/NAT) worked fine. However, since moving to the Cisco 881, inbound calls drop after around 10 seconds, whereas outbound calls work fine. The following message is logged on my Asterisk PBX: [Dec 9 15:27:45] WARNING[27734]: chan_sip.c:3641 retrans_pkt: Retransmission timeout reached on transmission [email protected] for seqno 1 (Critical Response) -- See https://wiki.asterisk.org/wiki/display/AST/SIP+Retransmissions Packet timed out after 6528ms with no response [Dec 9 15:27:45] WARNING[27734]: chan_sip.c:3670 retrans_pkt: Hanging up call [email protected] - no reply to our critical packet (see https://wiki.asterisk.org/wiki/display/AST/SIP+Retransmissions). (I know that this is quite a common issue - I've spend the best part of 2 days solid on this, trawling Google.) I've done as I am told and checked https://wiki.asterisk.org/wiki/display/AST/SIP+Retransmissions. Referring to the section "Other SIP requests" in the page linked above, I believe that the hangup to be caused by the ACK from my SIP provider not being passed back through NAT to Asterisk on my PBX. I tried to ascertain this by dumping the packets on my WAN interface on the 881. I managed to obtain a PCAP dump of packets in/out of my WAN interface. Here's an example of an ACK being reveived by the router from my provider: 689 21.219999 193.x.x.x 188.x.x.x SIP 502 Request: ACK sip:[email protected] | However a SIP trace on the Asterisk server show's that there are no ACK's received in response to the 200 OK from my PBX: http://pastebin.com/wwHpLPPz In the past, I have been strongly advised to disable any sort of SIP ALGs on routers and/or firewalls and the many posts regarding this issue on the internet seem to support this. However, I believe on Cisco IOS, the config command to disable SIP ALG is no ip nat service sip udp port 5060 however, this doesn't appear to help the situation. To confirm that config setting is set: Router1#show running-config | include sip no ip nat service sip udp port 5060 Another interesting twist: for a short period of time, I tried another provider. Luckily, my trial account with them is still available, so I reverted my Asterisk config back to the revision before I integrated with my current provider. I then dialled in to the DDI associated with the trial trunk and the call didn't get hung up and I didn't get the error above! To me, this points at the provider, however I know, like all providers do, will say "There's no issues with our SIP proxies - it's your firewall." I'm tempted to agree with this, as this issue was not apparent with the old WAG320N router when it was doing the NAT'ing. I'm sure you'll want to see my running-config too: ! !

Debian/Redmine: Upgrade multiple instances at once

- by Davey

I have multiple Redmine instances. Let's call them InstanceA and InstanceB. InstanceA and InstanceB share the same Redmine installation on Debian. Suppose I would want to install Redmine 1.3 on both instances, how would I do that? After upgrading the core files I would have to migrate the databases. What I would like to know is: can I migrate all databases in a single action? Normally I would do something like: rake -s db:migrate RAILS_ENV=production X_DEBIAN_SITEID=InstanceA for each instance, but this would get tedious if you have 50+ instances. Thanks in advance! Edit: The README.Debian file that's in the (Debian) Redmine package states: SUPPORTS SETUP AND UPGRADES OF MULTIPLE DATABASE INSTANCES This redmine package is designed to automatically configure database BUT NOT the web server. The default database instance is called "default". A debconf facility is provided for configuring several redmine instances. Use dpkg-reconfigure to define the instances identifiers. But can't figure out what to do with the "debconf facility". Edit2: My environment is a default Debian 6.0 "Squeeze" installation with a default Redmine (aptitude install redmine) installation on a default libapache2-mod-passenger. I have setup two instances with dpkg-reconfigure redmine.

Visual Studio 2010 Winform Application – Unable to resolve custom assemblies?

- by Harish Ranganathan

Recently I surfaced a problem where, one of my friend had a tough time in getting rid of an assembly reference error. Despite adding reference to the assembly, while referencing it in code, it was spitting out the “The type or namespace name ‘ASSEMBLYNAME’ could not be found” error. This was a migration project and owing to the above error, it was throwing another 100 errors. We tried adding reference to the assembly in other projects and it was not even resolving the namespace while typing out in the using section. Upon further digging into the error warnings, it indicated something to do with the .NET Framework targeted i.e. 4.0. My suspicion grew since the target framework was 4.0 and the assembly should be able to be recognized. Then, when we checked “Project – “<APPNAME> Properties…”, the issue was with the default target framework which is “.NET Framework 4 Client Profile” By default, Visual Studio 2010 creates Windows Forms App/WPF Apps with the Target Framework set to .NET Framework 4 Client Profile. This is to minimize the framework size required to be bundled along with the app. Client Profile is new feature since .NET 3.5 SP1 that allows users to package a minified version of .NET Framework that doesn’t include stuff such as ASP.NET, Server programming assemblies and few other assemblies which are typically never used in the Desktop Applications. Since the .NET Framework client profile is a minified version, it doesn’t contain all the assemblies related to Web services and other deprecated assemblies. However, this application is a migration app and needed some of the references from Services and hence couldn’t run. Once, we changed the Target Framework to .NET Framework 4 instead of the default client profile, the application compiled. Here is link to a very nice article that explains the features of .NET Framework 4 client Profile, the assemblies supported by default etc., http://blogs.msdn.com/b/jgoldb/archive/2010/04/12/what-s-new-in-net-framework-4-client-profile-rtm.aspx Cheers !!

Removing English - United States Language from Firefox Issue...

- by Paul

Win7 Home Prem 32bit Firefox 3.6.2 I noticed whilst typing a hotmail email in Firefox that the default language seems to be English/United States. As i am from the UK i thought i would add in the English/United Kingdom dictionary Addon which i have done. I have set this as the default Language. Is there anyway to remove the English/United States Dictionary? It is not an Addon so i'm guessing it's the built in Firefox default language and may be unremovable?

Disable .htaccess from apache allowoverride none, still reads .htaccess files

I have moved all of our .htaccess config into <Directory> blocks and set AllowOverride None in the default and default-ssl. Although after restarting apache it is still reading the .htaccess files.

When you need a different shutdown # approach you can use one of the following variables: # o ssl-unclean-shutdown: # This forces an unclean shutdown when the connection is closed, i.e. no # SSL close notify alert is send or allowed to received. This violates # the SSL/TLS standard but is needed for some brain-dead browsers. Use # this when you receive I/O errors because of the standard approach where # mod_ssl sends the close notify alert. # o ssl-accurate-shutdown: # This forces an accurate shutdown when the connection is closed, i.e. a # SSL close notify alert is send and mod_ssl waits for the close notify # alert of the client. This is 100% SSL/TLS standard compliant, but in # practice often causes hanging connections with brain-dead browsers. Use # this only for browsers where you know that their SSL implementation # works correctly. # Notice: Most problems of broken clients are also related to the HTTP # keep-alive facility, so you usually additionally want to disable # keep-alive for those clients, too. Use variable "nokeepalive" for this. # Similarly, one has to force some clients to use HTTP/1.0 to workaround # their broken HTTP/1.1 implementation. Use variables "downgrade-1.0" and # "force-response-1.0" for this.

Directives that define the parameters of the 'main' or 'default' server, # which responds to requests that aren't handled by a virtual host. # These directives also provide default values for the settings # of all virtual hosts. # 3. Settings for virtual hosts, which allow Web requests to be sent to # different IP addresses or hostnames and have them handled by the # same Apache server process. # # Configuration and logfile names: If the filenames you specify for many # of the server's control files begin with "/" (or "drive:/" for Win32), the # server will use that explicit path. If the filenames do *not* begin # with "/", the value of ServerRoot is prepended -- so "foo.log" # with ServerRoot set to "/etc/apache2" will be interpreted by the # server as "/etc/apache2/foo.log". # ### Section 1: Global Environment # # The directives in this section affect the overall operation of Apache, # such as the number of concurrent requests it can handle or where it # can find its configuration files. # # # ServerRoot: The top of the directory tree under which the server's # configuration, error, and log files are kept. # # NOTE!

Finding out what user Apache is running as?

- by Anna

I want to secure a file upload directory on my server as described beautifully here, but I have one problem before I can follow these instructions. I don't know what user Apache is running as. I've found a suggestion that you can look in httpd.conf and there will be a "User" line, but there is no such line in my httpd.conf file, so I guess Apache is running as the default user. I can't find out what that is, though. So, my question is (are): how do I find out what the default user is do I need to change the default user if the answer is yes and I change the default user by editing httpd.conf, is it likely to screw anything up? Thanks! ----- UPDATE ------ Seems to have been answered here. Sorry, I got told off on StackOverflow and told to post it here, then posted it here, then it got answered on StackOverflow anyway!

Powershell (sqlps) lastbackupdate not changing despite having run a sqlserver backup

- by user1666376

I'm using Powershell to check last backup times across all our sqlserver databases. This seems to work really well, but I've got a question If I run this (a cut-down version of the actual script): dir SQLSERVER:\SQL\Server1\default\databases | select parent, name, lastbackupdate I get: Parent Name LastBackupDate ------ ---- -------------- [Server1] ADBA 10/09/2012 21:15:37 [Server1] ReportServer 10/09/2012 21:00:17 [Server1] ReportServerTempDB 10/09/2012 21:00:18 [Server1] db1 10/09/2012 21:15:35 If I then run a sql backup of the Server1 default instance, and run the same query the last backup date doesn't change: PS C:\temp> dir SQLSERVER:\SQL\Server1\default\databases | select parent, name, lastbackupdate Parent Name LastBackupDate ------ ---- -------------- [Server1] ADBA 10/09/2012 21:15:37 [Server1] ReportServer 10/09/2012 21:00:17 [Server1] ReportServerTempDB 10/09/2012 21:00:18 [Server1] db1 10/09/2012 21:15:35 ..but if I open a new powershell window, it shows the backup I just took: PS SQLSERVER:\> dir SQLSERVER:\SQL\Server1\default\databases | select parent, name, lastbackupdate Parent Name LastBackupDate ------ ---- -------------- [server1] ADBA 12/09/2012 09:03:23 [server1] ReportServer 12/09/2012 08:48:03 [server1] ReportServerTempDB 12/09/2012 08:48:04 [server1] db1 12/09/2012 09:03:21 My guess is that this is expected behaviour, but could anybody show me where it's documented/explained - I just want to understand what's going on. This is running the SQlps which came with 2008, against a 2008 instance. Thanks Matt
