• How can I configure multiple default gateways on a CISCO Router?

  - by Spirit

  Does any one knows a way to configure a cisco router with multiple gateways - multiple gateways of last resort? I've tried adding a gateway of last resort twice (with different metric) but only one is shown: Router(config)# ip route 0.0.0.0 0.0.0.0 2.2.2.2 10 Router(config)# ip route 0.0.0.0 0.0.0.0 3.3.3.3 100 And the show ip route output was: Router# show ip route Gateway of last resort is 2.2.2.2 to network 0.0.0.0 2.0.0.0/24 is subnetted, 1 subnets C 2.2.2.0 is directly connected, FastEthernet0/0 3.0.0.0/24 is subnetted, 1 subnets C 3.3.3.0 is directly connected, FastEthernet0/1 32.0.0.0/30 is subnetted, 1 subnets C 32.2.2.0 is directly connected, Serial0/2/0 S* 0.0.0.0/0 [10/0] via 2.2.2.2 The point is that i cannot see the other route with higher distance metric? Anyone has a sugestion? I mean will this config work if the link on 2.2.2.2 fails? Will the router choose the other network 3.3.3.3, if the link 2.2.2.2 fails?

• How to set up multiple SSIDs with bandwidth limiting on a single wireless router?

  - by Rahul Narain

  I have an Asus WL-520GU wireless router connected to a cable modem that I use for wireless internet access in my apartment. I would like to set it up so that it provides two SSIDs: one secured and password-protected for my regular use, and a "guest" SSID that's unsecured but throttled to, say, 10% of the available bandwidth. What is the most straightforward way to do this? I've been looking into DD-WRT and Tomato, both of which support my router. DD-WRT supports setting up multiple SSIDs using the GUI, but I don't know if it's possible to limit the bandwidth of each SSID independently; point #12 in this FAQ thread says it's not possible to limit by day or by MAC address, which is discouraging but not conclusive. Tomato allows bandwidth limits in its QoS settings, going by the screenshot here, but multiple SSID support is still experimental and it doesn't look like it will work with the encryption settings or bandwidth limits in the GUI. I'd like to know a good way to do this which gives me the fewest opportunities for screwing up. I'm no stranger to the command line, if that turns out to be what's necessary, but if so, please explain what the commands are doing because I don't have a good mental model of what needs to happen to set this up.

• Implications of Multiple JobTracker nodes in a Hadoop cluster?

  - by Jim Dennis

  I get the impression that one can, potentially, have multiple JobTracker nodes configured to share the same set of MR (TaskTracker) nodes. I know that, conventionally, all the nodes in a Hadoop cluster should have the same set of configuration files (conventionally under /etc/hadoop/conf/ --- at least for the Cloudera Distribution of Hadoop (CDH). Can we define multiple Job Trackers in mapred-site.xml? Something like: <configuration> <property> <name>mapred.job.tracker</name> <value>jt01.mydomain.not:8021</value> </property> <property> <name>mapred.job.tracker</name> <value>jt02.mydomain.not:8021</value> </property> ... </configuration> Or is there some other allowed syntax for this? What are the implications of doing this. Does each JobTracker get information about the load on each TaskTracker node. In other words can the two JobTracker co-ordinated their scheduling across the TT nodes only based on the gossip information from the TTs or would they need to talk to one another? Is this documented anywhere?

• Join multiple consecutive SQLite database dump files into 1 common database? Purpose: Search through ENTIRE Chrome Browsing History

  - by porg

  Google Chrome 's default web browsing history search engine only lets you access the records of the recent 100 days. Nevertheless in your application data, Chrome keeps your entire browsing history in SQLite database files, with the file naming scheme of "History Index YYYY-MM". I am looking for a way to search… …through my entire browsing history, …with sophisticated filters (limit search terms to certain fields such as URL, domain, title, body text; wildcard or regex terms, date ranges). … in … …either some ready-made software. eHistory came close, as it can limit terms to fields, but it lacks wildcards/regexes, and has the same limited time horizon as the default search. Beyond that, I could not find any suited Chrome extension or standalone (Mac) app. …or a command line to join multiple SQLite database files into one database, which I can then query (with the full syntax power). In the spirit of the pseudo code below: Preferred this way: sqlite --targetDatabase ChromeHistoryAll --importFiles /path/to/ChromeAppData/History\ Index* --importOnlyYetUnknownFiles Or if my desired feature --importOnlyYetUnknownFiles is not possible (feature could also be called "avoid duplicate imports by checking UIDs"), then by explicitly only importing files, of which I know, that they have yet not been imported into the ChromeHistoryAll database: cd ChromeAppData; sqlite --databaseTarget ChromeHistoryAll --importFiles YetNotImported1 YetNotImported2 YetNotImported3 All my queries I would then perform in the database "ChromeHistoryAll" P.S.: Additional question of general interest: Is there a way to perform a database query in a temporary database which was created on-the-fly from multiple files? Like: sqlite --query="SQL query" --targetDatabase DbAll --DBtemporaryInRAM --importFiles db1 db2 db3 This is surely not applicable for my Chrome question, as these History Index files have a combined file size of 500MB together, thus such a query would be of bad performance. But it could come handy in other situations.

• Slicing the EDG

  - by Antony Reynolds

  Different SOA Domain Configurations In this blog entry I would like to introduce three different configurations for a SOA environment.  I have omitted load balancers and OTD/OHS as they introduce a whole new round of discussion.  For each possible deployment architecture I have identified some of the advantages. Super Domain This is a single EDG style domain for everything needed for SOA/OSB.   It extends the standard EDG slightly but otherwise assumes a single “super” domain. This is basically the SOA EDG.  I have broken out JMS servers and Coherence servers to improve scalability and reduce dependencies. Key Points Separate JMS allows those servers to be kept up separately from rest of SOA Domain, allowing JMS clients to post messages even if rest of domain is unavailable. JMS servers are only used to host application specific JMS destinations, SOA/OSB JMS destinations remain in relevant SOA/OSB managed servers. Separate Coherence servers allow OSB cache to be offloaded from OSB servers. Use of Coherence by other components as a shared infrastructure data grid service. Coherence cluster may be managed by WLS but more likely run as a standalone Coherence cluster. Benefits Single Administration Point (1 Admin Server) Closely follows EDG with addition of application specific JMS servers and standalone Coherence servers for OSB caching and application specific caches. Coherence grid can be scaled independent of OSB/SOA. JMS queues provide for inter-application communication. Drawbacks Patching is an all or nothing affair. Startup time for SOA may be slow if large number of composites deployed. Multiple Domains This extends the EDG into multiple domains, allowing separate management and update of these domains.  I see this type of configuration quite often with customers, although some don't have OWSM, others don't have separate Coherence etc. SOA & BAM are kept in the same domain as little benefit is obtained by separating them. Key Points Separate JMS allows those servers to be kept up separately from rest of SOA Domain, allowing JMS clients to post messages even if other domains are unavailable. JMS servers are only used to host application specific JMS destinations, SOA/OSB JMS destinations remain in relevant SOA/OSB managed servers. Separate Coherence servers allow OSB cache to be offloaded from OSB servers. Use of Coherence by other components as a shared infrastructure data grid service. Coherence cluster may be managed by WLS but more likely run as a standalone Coherence cluster. Benefits Follows EDG but in separate domains and with addition of application specific JMS servers and standalone Coherence servers for OSB caching and application specific caches. Coherence grid can be scaled independent of OSB/SOA. JMS queues provide for inter-application communication. Patch lifecycle of OSB/SOA/JMS are no longer lock stepped. JMS may be kept running independently of other domains allowing applications to insert messages fro later consumption by SOA/OSB. OSB may be kept running independent of other domains, allowing service virtualization to continue independent of other domains availability. All domains use same OWSM policy store (MDS-WSM). Drawbacks Multiple domains to manage and configure. Multiple Admin servers (single view requires use of Grid Control) Multiple Admin servers/WSM clusters waste resources. Additional homes needed to enjoy benefits of separate patching. Cross domain trust needs setting up to simplify cross domain interactions. Startup time for SOA may be slow if large number of composites deployed. Shared Service Environment This model extends the previous multiple domain arrangement to provide a true shared service environment.This extends the previous model by allowing multiple additional SOA domains and/or other domains to take advantage of the shared services.  Only one non-shared domain is shown, but there could be multiple, allowing groups of applications to share patching independent of other application groups. Key Points Separate JMS allows those servers to be kept up separately from rest of SOA Domain, allowing JMS clients to post messages even if other domains are unavailable. JMS servers are only used to host application specific JMS destinations, SOA/OSB JMS destinations remain in relevant SOA/OSB managed servers. Separate Coherence servers allow OSB cache to be offloaded from OSB servers. Use of Coherence by other components as a shared infrastructure data grid service Coherence cluster may be managed by WLS but more likely run as a standalone Coherence cluster. Shared SOA Domain hosts Human Workflow Tasks BAM Common "utility" composites Single OSB domain provides "Enterprise Service Bus" All domains use same OWSM policy store (MDS-WSM) Benefits Follows EDG but in separate domains and with addition of application specific JMS servers and standalone Coherence servers for OSB caching and application specific caches. Coherence grid can be scaled independent of OSB/SOA. JMS queues provide for inter-application communication. Patch lifecycle of OSB/SOA/JMS are no longer lock stepped. JMS may be kept running independently of other domains allowing applications to insert messages fro later consumption by SOA/OSB. OSB may be kept running independent of other domains, allowing service virtualization to continue independent of other domains availability. All domains use same OWSM policy store (MDS-WSM). Supports large numbers of deployed composites in multiple domains. Single URL for Human Workflow end users. Single URL for BAM end users. Drawbacks Multiple domains to manage and configure. Multiple Admin servers (single view requires use of Grid Control) Multiple Admin servers/WSM clusters waste resources. Additional homes needed to enjoy benefits of separate patching. Cross domain trust needs setting up to simplify cross domain interactions. Human Workflow needs to be specially configured to point to shared services domain. Summary The alternatives in this blog allow for patching to have different impacts, depending on the model chosen.  Each organization must decide the tradeoffs for itself.  One extreme is to go for the shared services model and have one domain per SOA application.  This requires a lot of administration of the multiple domains.  The other extreme is to have a single super domain.  This makes the entire enterprise susceptible to an outage at the same time due to patching or other domain level changes.  Hopefully this blog will help your organization choose the right model for you.

• OS X, Mercurial and MediaTemple problem

  - by bschaeffer

  I've installed Mercurial per MT's knowledge base file here. Working with it server side using ssh from my Mac works fine. I can initialize repositories and the like, but pulling from the server or pushing from my Mac produces an error I don't understand. Here's what I get when call hg push from my local installation (hash marks represent my server number): remote: Traceback (most recent call last): remote: File "/home/#####/users/.home/data/mercurial-1.5/hg", line 27, in ? remote: mercurial.dispatch.run() remote: File "/nfs/c05/h01/mnt/#####/data/mercurial-1.5/mercurial/dispatch.py", line 16, in run remote: sys.exit(dispatch(sys.argv[1:])) remote: File "/nfs/c05/h01/mnt/#####/data/mercurial-1.5/mercurial/dispatch.py", line 21, in dispatch remote: u = _ui.ui() remote: File "/nfs/c05/h01/mnt/#####/data/mercurial-1.5/mercurial/ui.py", line 38, in __init__ remote: for f in util.rcpath(): remote: File "/nfs/c05/h01/mnt/#####/data/mercurial-1.5/mercurial/util.py", line 1200, in rcpath remote: _rcpath = os_rcpath() remote: File "/nfs/c05/h01/mnt/#####/data/mercurial-1.5/mercurial/util.py", line 1174, in os_rcpath remote: path = system_rcpath() remote: File "/nfs/c05/h01/mnt/#####/data/mercurial-1.5/mercurial/posix.py", line 41, in system_rcpath remote: path.extend(rcfiles(os.path.dirname(sys.argv[0]) + remote: File "/nfs/c05/h01/mnt/#####/data/mercurial-1.5/mercurial/posix.py", line 30, in rcfiles remote: rcs.extend([os.path.join(rcdir, f) remote: File "/nfs/c05/h01/mnt/#####/data/mercurial-1.5/mercurial/demandimport.py", line 75, in __getattribute__ remote: self._load() remote: File "/nfs/c05/h01/mnt/#####/data/mercurial-1.5/mercurial/demandimport.py", line 47, in _load remote: mod = _origimport(head, globals, locals) remote: ImportError: No module named osutil abort: no suitable response from remote hg!

• Why do I recieve multiple warnings of "No running instance of xfce4-panel was found" when logging into Xubuntu?

  - by Fredrik

  I'm running Xubuntu 11.04, the bootup-time is quite fast but when I log in it takes close to a minute before the desktop is displayed, meanwhile I see no activity on the hard drive. When I finally have the desktop I see this notification repeated 10 times: and then this one: In .config/autostart I have these entries $ ls xfce4-settings-helper-autostart.desktop xfce4-clipman-plugin-autostart.desktop xfce-panel.desktop $ cat xfce-panel.desktop [Desktop Entry] Encoding=UTF-8 Version=0.9.4 Type=Application Name=xfce4-panel Comment= Exec=xfce4-panel StartupNotify=false Terminal=false Hidden=false I need some assistance to locate the slow startup, which logs to look at etc. And then this annoying message about xfce-panel. Where do I look for from where it is started.

• Mercurial over ssh client and server on Windows

  - by Ben Von Handorf

  I'm trying to configure Mercurial for use with both a windows server (freeSSHd) and client (both command line and TortoiseHG). I'm using the most recent versions of everything... all downloaded in the past few days. Using public key auth, I have been able to get connected to the server and I'm able to use plink to execute "hg version" and get a response, but when I try to clone a repository from the ssh server the command appears to hang. Running with -v yields: hg -v clone ssh://<username>@<server>//hg/repositoryA testRepositoryA running "plink.exe -i "<path to private key file>" <username>@<server> "hg -R /hg/repositoryA serve --stdio"" with nothing more forthcoming. Running the hg serve command directly on the server yields an apparently responsive Mercurial server, but the clients do not seem to make any further requests. Running "hg serve" in the repository directory and cloning over http works perfectly. What should I be looking for to help debug this? Is there something the clients (hg and TortoiseHG) aren't sending to continue the request stream? Additional Information: If I change to an invalid repository on the target machine, the appropriate error is displayed, so it does appear that the remote hg is running and correctly evaluating the path. Running with --debug and --traceback results in: sending hello command sending between command It hangs here, until I CTRL-C Traceback (most recent call last): File "mercurial\dispatch.pyo", line 46, in _runcatch File "mercurial\dispatch.pyo", line 452, in _dispatch File "mercurial\dispatch.pyo", line 320, in runcommand File "mercurial\dispatch.pyo", line 504, in _runcommand File "mercurial\dispatch.pyo", line 457, in checkargs File "mercurial\dispatch.pyo", line 451, in <lambda> File "mercurial\util.pyo", line 402, in check File "mercurial\commands.pyo", line 636, in clone File "mercurial\hg.pyo", line 187, in clone File "mercurial\hg.pyo", line 63, in repository File "mercurial\sshrepo.pyo", line 51, in __init__ File "mercurial\sshrepo.pyo", line 73, in validate_repo KeyboardInterrupt interrupted! Responding to Ryan: There does not appear to be any CPU usage or increasing memory usage on the server. It appears to be waiting for the client to send a request or something similar. 11/19/2009 : More information: The problem is definitely in the freeSSHd/server side of the equation. Connecting to bitbucket over ssh with the same keyset works fine. Still working on this.

• Analiytics: Can I set a goal on multiple events?

  - by David Parks

  We have a popup dialogue that requests users email address or facebook login. The page behind the popup loads, so a page view is counted. We want to measure: How many users ignored the popup completely How many users engaged the popup, but don't complete the process (we trigger an event when the user performs actions defined as "engaging") How many users completed the popup Bounce rates aren't telling because some users won't receive the popup. We are basically triggering events "PopupDisplayed" "PopupEngaged" and "PopupComplete", with labels to differentiate between email and facebook. But I don't think I can set goals to count "Users who received 'PopupDisplayed' AND 'PopupComplete'" events, so I can count how many users both saw the popup and completed it.

• Should I use the same AddThis tag on multiple sites?

  I have an AddThis for one site: <script type="text/javascript" src="http://s7.addthis.com/js/250/addthis_widget.js#pubid=ripper234"> </script> Now I logged into AddThis and wanted to get my tag again, I saw it changed: <script type="text/javascript" src="http://s7.addthis.com/js/300/addthis_widget.js#pubid=ripper234"> </script> Should I use the same tag I got before, or the new tag? What's the difference? Is 250/300 the internal version number?

• Ubuntu One Sync for multiple folders, not just the Ubuntu One folder.

  - by bisi

  Hello, I may have misunderstood Ubuntu One as a service, but this is how I had pictured it. At home, I tagged a few folders with the "Sync to Ubuntu One" tick and it started uploading. Now back at work, on Win7, I installed Ubuntu One and thought I was going to be able to tick which of the backed-up folders I could download/sync to this machine. From what I gather after a little research is that whatever I would like to synchronize would need to be in the Ubuntu One folder? There is no way to do this outside of that? Thanks for confirming, or informing me whether this will be introduced in the future as an option? Thank you very much for your help on this! bisi

• How should I log time spent on multiple tasks?

  - by xenoterracide

  In Joel's blog on evidence based scheduling he suggests making estimates based on the smallest unit of work and logging extra work back to the original task. The problem I'm now experiencing is that I'll have create object A with subtask method A which creates object B and test all of the above. I create tasks for each of these that seems to be resulting in ok-ish estimates (need practice), but when I go to log work I find that I worked on 4 tasks at once because I tweak method A and find a bug in the test and refactor object B all while coding it. How should I go about logging this work? should I say I spent, for example, 2 hours on each of the 4 tasks I worked on in the 8 hour day?

• Is there a pattern or best practice for passing a reference type to multiple classes vs a static class?

  - by Dave

  My .NET application creates HTML files, and as such, the structure looks like variable myData BuildHomePage() variable graph = new BuildGraphPage(myData) variable table = BuildTablePage(myData) BuildGraphPage and BuildTablePage both require access data, the myData object. In the above example, I've passed the myData object to 2 constructors. This is what I'm doing now, in my current project. The myData object, and it's properties are all readonly. The problem is, the number of pages which will require this object has grown. In the real project, there are currently 4, but the new spec is to have about 20. Passing this object to the constructor of each new object and assigning it to a field is a little time consuming, but not a hardship! This poses the question whether it's better practice to continue as I have, or to refactor and create a new static class for myData which can be referenced from any where in my project. I guess my abilities to use Google are poor, because I did try and find an appropriate pattern as I am sure this type of design must be common place but my results returned nothing. Is there a pattern which is suited, or do best practices lean towards one implementation over another.

• To have multiple sites with similar content on the same server but different IPs?

  - by Eugene

  I have 7 different sites on the same dedicated server. Two major sites have different IPs, and 5 small share the same IP. About first 2 they have similar content, but not the same. Basically they have different: URLs Titles Meta Data But they both have the same niche. I was thinking about two strategies. One is to move one of the sites (from 2 first one) on different server or move 5 other sites on different server. But I'm not sure which way is better. My questions are: Wouldn't be better from SEO stand point, to move those 2 sites on different servers? Does it worth it to spend for additional server? Do you know if Google penalize sites for similar content on the same server with different IPs?

• Is there a Content Management System that allows multiple & independent blogs to be running on one domain?

  - by Ron

  Hello Webmasters, I am a Wordpress fan, and I'm now building a new site and I'm not sure which CMS can achieve what I'm trying to do. I am building a food blog network for a bunch of cities in the US, and I want to my city pages to be independently running blogs themselves. So basically... Home Page - Its own blog with its own users, talking about Food in general Dallas Page (child of home page) - Its own blog with its own users Chicago Page ..... so on and so forth. The web layout and design will be all the same, but just trying to achieve 25~50 independent blogs on one domain. How can I achieve this? I'm hoping that I don't have to install Wordpress into as many subdomains that I create... Thank you for your help in advance. -RP

• Why do people have to use multiple versions of jQuery in the same page?

  - by reprogrammer

  I have noticed that sometimes people have to use multiple versions of jQuery in the same page (See question 1 and question 2). I assume people have to carry old versions of jQuery because some pieces of their code is based on an older version of jQuery. Obviously, this approach causes inefficiency. The ideal solution is to refactor the old code to use the newer jQuery API. I wonder if there are tools that automate the process of upgrading a piece of code to use a newer version of jQuery. I've never written programs in in either Javascript or jQuery. So, I'd like to hear from programmers experienced in these language about their opinion on this issue. In particular, I'd like to know the following. How much of problem it is to have to load multiple versions of jQuery? Have you ever had to load multiple versions of any other library in the same page? Do you know of any refactoring tools that helps you migrate your code to use the updated API? Do you think such a refactoring tool is useful? Are you willing to use it?

• Business operates in multiple counties, will adding a listing in the Local Business sites harm our placement in SERPs?

  - by leeand00

  I work at a non-profit where we operate in more than two counties within our state. Our offices are located in two different towns, and that leaves a few counties of operation where we would also like to appear in their local SERPs or Local Business listings. Please note that these towns are not necessarily close to all the areas of operation. Since we don't have offices in all the counties of operation, how can we effectively post our business in the Local Business Listings and still show up in our counties of operation?

• How do I detect multiple sprite collisions when there are >10 sprites?

  - by yao jiang

  I making a small program to animate the astar algorithm. If you look at the image, there are lots of yellow cars moving around. Those can collide at any moment, could be just one or all of them could just stupidly crash into each other. How do I detect all of those collisions? How do I find out which specific car has crash into which other car? I understand that pygame has collision function, but it only detects one collision at a time and I'd have to specify which sprites. Right now I am just trying to iterate through each sprite to see if there is collision: for car1 in carlist: for car2 in carlist: collide(car1, car2); This can't be the proper way to do it, if the car list goes to a huge number, a double loop will be too slow.

• How do I link external style sheet to multiple pages and folders?

  - by user18681

  im building a pretty large website that will have many pages and folders. I have 1 stylesheet. How do I add the style sheet to "ALL" of these folders? I didnt have this problem before I started to put the pages in SEPERATE folders. Now that each page has its own folder it no longer reads my stylesheet unless its in the SAME folder Example, lets say I have a folder of pets, another of cars, and another of planes. I have to put my stylesheet in EACH and everyone of these folders so that I can see my site. How can I do it so that I do NOT have to put a stylesheet in each and every folder? In other words how can I get my stylesheets on the same page as my folders without having them in that folder? How can I get them to communicate while being in a different folder?

  Problem In the last couple weeks, I've used 3 different "repository" tools (listed in alphabetical order): gradle ivy maven I'm calling them "repository" tools because I've also used sbt -- which fortunately uses ivy to manage it's cache or local repository. Each of these tools will create it's own repository. The defaults are: ~/.m2/repository for maven ~/.gradle/cache ~/.ivy2/cache Why can't they all use the same cache? Goal I'd like to change the world so that all three build tools could use the same cache. I'm looking for advice about issues I'm likely to run into and smart ways to get around them. By "use the same cache", I do not mean "retrieve from another build tool's cache". I mean "retrieve from and store in another build tool's cache". While I could go ahead and submit issues to the three projects, I know from experience (as a developer on an open source project), that if you want something done, you're best off getting it done yourself. Also, it seems like I need to get all 3 communities on board to some degree. What is the recommended approach for getting this kind of thing done? How do I approach the different communities? Do I work on patches for the 3 different projects, or would it be better off to create my own "interface" project that deals with these issues and have the 3 tools interface with that? Is this a standards question that I need to address on that front? Lastly, if I'm missing something and this is possible (in an globally configurable fashion), then please let me know.

• How do you manage frequent software releases to multiple clients?

  - by meeech

  hi we have a cross-platform middleware product which we typically end up customizing/bug fixing on a per client basis. In some cases, providing updates as often as once/twice per week. We have a lot of trouble efficiently managing and releasing the updates to our clients. I've done some digging, but I can't find anything to specifically address this problem. Can anyone share their experiences - how do you deal with this scenario, or do you know of a good software delivery cms? thanks

• How do create an encrypted system with multiple Linux distributions?

  - by niels

  A few weeks ago I created a completely encrypted system on a notebook and must say I like the idea. It's a little bit annoying to enter the password on every boot, but it's nice to know even if I loose the computer I don't give my data to other people. With the alternate-cd it's easy to do. Now I have to setup a new system where I want to combine the new idea with my usual usage strategy. There I have more partitions: 3 system, Home, Different Data-Partitions for vm-data, photo-data and mp3-data. The background is that I prefer not to update a system. I prefer to install the new version parallel to the old system. So I can easily test it. Obviously the Data-Partitions are used for both systems. My questions is, how can I easily combine both my strategy and the crypto-approach? Or is it impossible. The way to do the crypted stuff by hand is in my eyes to complicated.
