  • Routing tables don't show ppp0 after 12.04 kernel upgrade to 3.5.0: Haier CE682 modem configuration

    - by ubunsteve
    I'm trying to get my Haier CE682 EVDO modem, model number 201e:1022 to work in ubuntu 12.04 kernel 3.5.0-030500-generic #201207211835 . I had it working in a previous 12.04 kernel, using compat-wireless and these instructions http://zulkhamsyahmh.blogspot.com/2012/05/install-smartfren-haier-ce682-on-ubuntu.html, and to get it working had to edit the routing tables so that there was a ppp0 showing up, as suggested at http://www.linuxquestions.org/questions/slackware-14/wvdial-is-connecting-but-im-unable-to-do-anything-714861/ Network manager doesn't work with this modem, so I use either wvdial or gpppon to connect to it, both which work (after I run the command sudo modprobe usbserial vendor=0x201e product=0x1022 ) This is the output of when I connect with gpppon to the modem: Using interface ppp0 Connect: ppp0 <-- /dev/ttyUSB0 sent [LCP ConfReq id=0x1 ] rcvd [LCP ConfAck id=0x1 ] rcvd [LCP ConfReq id=0x2 ] sent [LCP ConfAck id=0x2 ] sent [LCP EchoReq id=0x0 magic=0x819c86db] rcvd [CHAP Challenge id=0x1 <1ac8f12799e953967a3cc222c9254690, name = ""] sent [CHAP Response id=0x1 <6f12a903dc40915ca2761c17b87f8fbd, name = "smart"] rcvd [LCP EchoRep id=0x0 magic=0x0] rcvd [CHAP Success id=0x1 ""] CHAP authentication succeeded CHAP authentication succeeded sent [CCP ConfReq id=0x1 ] sent [IPCP ConfReq id=0x1 ] rcvd [IPCP ConfReq id=0x1 ] sent [IPCP ConfAck id=0x1 ] rcvd [CCP ConfReq id=0x1] sent [CCP ConfAck id=0x1] rcvd [CCP ConfRej id=0x1 ] sent [CCP ConfReq id=0x2] rcvd [IPCP ConfRej id=0x1 ] sent [IPCP ConfReq id=0x2 ] rcvd [CCP ConfAck id=0x2] rcvd [IPCP ConfNak id=0x2 ] sent [IPCP ConfReq id=0x3 ] rcvd [IPCP ConfAck id=0x3 ] not replacing existing default route via 192.168.3.1 local IP address 10.191.248.154 remote IP address 10.17.95.25 primary DNS address 10.17.3.244 secondary DNS address 10.17.3.245 as you can see there is a problem with "not replacing existing default route via 192.168.3.1" This it the out put of route Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface default 192.168.3.1 0.0.0.0 UG 0 0 0 wlan0 link-local * 255.255.0.0 U 1000 0 0 wlan0 192.168.3.0 * 255.255.255.0 U 2 0 0 wlan0 I had tried these commands, which had previously worked in the earlier kernel: route del default route add default ppp0 but that broke my wireless internet connection. I then added the default routing as shown above with sudo route add default gw 192.168.3.1 wlan0 So it seems I need to add or change the routing to show a ppp0 connection, but I don't know how to do that.

  • unreachable subnet in one direction

    - by Carl Michaud
    I'm unable to route traffic to a subnet in my home. Here's my topology: INET <- Router A <- Router B <- WIFI AP where: Router A - ARRIS TG862G/CT (from comcast) - WAN DHCP, LAN 10.0.0.99 Router B - Linksys WRT400N with DD-WRT - WAN 10.0.0.12 , LAN 10.0.1.1 I was able to use DD-WRT to configure a static route for the 10.0.1.x network back to the 10.0.0.x network. But I'm not sure if i can do the reverse on the ARRIS router and was looking for suggestions on how to fix that. I've set things up this wasy because I am using OpenDNS to mange internet content for my kids and of course I wasn't able to configure DNS to my liking on Router A either. So at present I'm using Router A on 10.0.0.x to provide a private unfiltered WIFI AP (no ssid broadcast) that I use for netflix only and then I use router B to provide a filtered WIFI AP for the rest of my WIFI devices on 10.0.1.x. However I would like to be able to connect to my 10.0.1.x devices from the internet via dynamic dns; but I can't see anything behind router B this way. Thoughts?

  • How to make ip Address static (eth0)

    - by Jordan Angelucci
    I'm having a really hard time configuring ubuntu 13.04 to have a static ip address.

  • Web hosting company basically forces me to use their domain name [closed]

    - by Jinx
    I've recently stumbled upon an unusual problem with one of hosting companies called giga-international.com. Anyway, I've ordered com.hr domain from Croatian domain name registration company, and my client insisted on using this host provider as couple of his friends already are hosted with them. I thought something was fishy when the first result on Google for Giga International was this little forum rant instead of their webpage. When I was checking their services they listed many features etc... space available, bandwidth etc. I just wanted to check how much ram do I get for my PHP scripts so I emailed them, and they told me that was company secret. Seriously? Anyway, since my client still insisted on hosting with them I've bought their Webspace package. During registration I had to choose free domain name because I couldn't advance registration without it. Nowhere was said, not even in general terms and conditions that I wouldn't be able to change that domain name. At least not for double the price of domain name per year. They said I can either move my domain name over to them (and pay them domain registration), or pay them 1 Euro per month for managing a DNS entry. On any previous hosting solution I was able to manage my domain names just by pointing my domain to their name servers, and this is something completely new and absurd for me. They also said that usual approach is not possible because of security and hardware limitations. I'd like to know what you guys think about this case, and should I report, and where should I report this case. In short. They forced me to register free domain name which doesn't suit my needs in order to register for their webspace package, and refuse to change domain name for my account until I either transfer domain to them or pay them DNS management which costs double the price of the domain name per year.

  • How do I get dynamic subdomains on domain aliases in Plesk? [closed]

    - by mitchdesign
    I am running a site that is available via many domains. So all domains depend on the same code, but depending on the requested domain, the correct information is shown to the user. In Plesk, I have one domain set up and it has domain aliases for all the others. This works ok. Now, I'd like to be able to use subdomains on those aliased domains. Like the domains, the subdomains will be used as input for the system to display the correct information. So, they are not a fixed set. What I have done: - In DNS I have added *.example.com CNAME example.com to the main domain. This is automatically copied by Plesk to all the aliases. So DNS-wise, I think it's ok. - I have added a vhost.conf file to the main domain, containing ServerAlias *.maindomain.tld. This works for the main domain. But still, not for the aliased domains. And there is no place to put vhost.conf files for the aliased domains.. How do I tell the server to respond to those domain's subdomains as well?

  • Mirroring of Apps across servers

    - by user1038814
    We wish to host multiple apps across multiple servers. What we are looking for (ideally) is an existing solution which will work. For example, normally to do it we'd follow a route (for failover) like: App is installed on one server along with mysql database App is also installed on a second server. Rsync is used to mirror the files over to the second server and ensure consistency MySQL is installed with a Master-Slave setup. We use a service such as DNS Made Easy which has a DNS failover. If one server goes down it automatically routes traffic to the backup server We have done the above a few times and generally its fine. The issue I have here is that the above is for one app. What I would like to look at is how we can manage for multiple apps and if there is a layer (such as VMWare) that has complete mirroring built in at the OS level? For example how do web hosts currently do it when they ensure that more than one machine is running a bunch of hosted websites. If you were running hosting and you had 200 clients on a server you would want the same clients across 2 or more servers and want everything mirrored. Any advice would be much appreciated.

  • Why won't Webmaster Tools let me set a preferred domain? (says to verify, but it should already be)

    - by Su'
    I've got a domain that I apparently forgot to set a preferred domain for, so I just tried to do it. Webmaster Tools instead popped up a little box: Part of the process of setting a preferred domain is to verify that you own http://www.example.com/. Please verify http://www.example.com/. I'm running into some problems following these instructions: As far as I can tell I already did verify sometime in the past. There's a TXT DNS record with the gibberish Google tells you to set for it that I couldn't have come up with myself. …and nothing is telling me this information is bad. So let's assume the site is somehow not actually verified. All the various methods' instructions start with "click the Manage Site button next to the site you want, and then click Verify this site." That button doesn't even exist on my screens. (It presumably goes away when you successfully verify?) Those instructions were all updated pretty recently, and the DNS one in particular just a couple weeks ago so it seems a bit unlikely they're inaccurate. I am not using Apps, and won't be, so can't try out the verification through there. Note that I also have another domain that I have not done any verification for which is showing the same behavior(no such button, being told to verify when it seems impossible etc.) so something appears to just be broken. I already have a no-www process in place server-side, so we can skip that. I'm just trying to get the box checked off in GWT. If I don't get any resolution, I'll eventually scrap the TXT record and see if the site gets un-verified(or whatever since it thinks it isn't), and see if I can just restart the process. It's not urgent so I'm just trying to figure out if I've gone blind to something or what. Did the button move?

  • Add Your Own Domain to Your WordPress.com Blog

    - by Matthew Guay
    Now that you’ve got a nice blog on WordPress.com, why not get your own domain to brand your site?  Here’s how you can easily register a new domain or move your existing domain to your WordPress site. By default, your free WordPress address is yourblog’sname.wordpress.com.  But whether this is a personal or a company blog, it can be nice to have your own domain to really brand your site and make it your own.  Or, if you already have another website and want to use WordPress as a blog for it, you could even add blog.yoursite.com or any other subdomain. Adding a domain to your WordPress.com is a paid upgrade; registering and mapping a new domain to your account costs $14.97 a year, while mapping a domain you already own to your WordPress blog costs $9.97 a year. Getting Started Login to your blog’s dashboard, click the arrow beside Upgrades in the sidebar, and select Domains. Enter the domain or subdomain you want to add to your site in the text box, and click Add domain to blog.   If you entered a new domain you want to register, WordPress will make sure the domain is available and then present you a registration form to register the domain.  Enter your information, and then click Register Domain.   Or, if you enter a domain that’s already registered, you will see the following prompt. If this domain is a domain you own, you can map it to WordPress.com.  Login to your domain registrar account and switch your nameserver to: NS1.WORDPRESS.COM NS2.WORDPRESS.COM NS3.WORDPRESS.COM Your DNS settings page for your domain may be different, depending on your registrar.  Here’s how our domain settings looked. Alternately, if you’re wanting to map a subdomain, such as blog.yoursite.com to your WordPress blog, create the following CNAME record on your domain register.  You may have to contact your domain registrar’s support to do this.  Substitute your subdomain, domain, and blog name when creating the record. subdomain.yourdomain.com. IN CNAME yourblog.wordpress.com. Once your settings are correct, click Try Again in your WordPress dashboard.  The DNS settings may take a while to update, but once WordPress can tell your DNS settings point to it, you will see the following confirmation screen.  Click Map Domain to add this domain to your WordPress blog. Now you’re ready to pay for your domain mapping or registration.  Depending on your purchase, the information and price shown may be different.  Here we’re mapping a domain we already have registered, so it costs $9.97.  Select your method of payment, enter your payment information or signin with your Paypal account, and continue as usual. Once your purchase is finished, you’ll be returned to the Domains page on WordPress.  Try going to your new domain, and make sure it opens your blog.  If it works, then click the bullet beside the new domain, and click Update Primary Domain.  Now, when people visit your WordPress site, they’ll see your new domain in the address bar.  You can still access your blog from your old yourname.wordpress.com address, but it will redirect to you new domain. Conclusion Having a personalized domain is a great way to make your blog more professional, while still taking advantage of the ease of use that WordPress.com offers.  And, if you have your own domain, you can easily move to your site traffic to a different hosting provider in the future if you need to.  The process is slightly complicated, but for $15/year we found this one of the best upgrades you could do to your WordPress.com blog. If you want to see an example of a site created with Wordpress, check out Matthew’s tech site techinch.com.

  • How To Configure Remote Desktop To Hyper-V Guest Virtual Machines

    - by Brian Jackett
    Configuring Remote Desktop (RDP) from a host Hyper-V machine to a guest virtual machine can be tricky, so this post is dedicated to the issues and resolution steps I went through to allow RDP.  Cutting to the point, below are the things to look for followed by some explanation about my scenario if you care to read.  This is not an exhaustive list of what is required, just the items that were causing problems for my particular scenario. Requirements Allow Remote Desktop Connections in guest OS. The network adapter type must allow communication with host machine (e.g. use an “Internal” virtual adapter.) If running Server 2008 R2 on guest, network discovery mode must be turned on. If running Server 2008 R2 on guest, the services supporting network discovery mode must be running: - DNS Client - Function Discovery Resource Publication - SSDP Discovery - UPnP Device Host My Environment     A quick word about my environment.  I am running Windows Server 2008 R2 with Hyper V on my laptop and numerous guest VMs running Windows Server 2003 R2 or Windows Server 2008 R2.  I run a domain controller VM and then 1 or 2 SharePoint servers depending on my work needs.  I’ve found this setup to work well except when it comes to the display window for my VMs. The Issue     Ever since I began running Hyper-V I haven’t been able to RDP to my guest VMs which means the resolution for my connection windows ha been limited to what the native Hyper-V connections allow.  During personal use I can put the resolution up to 1152 x 864, but during presentations I am usually limited to a measly 800 x 600.  That is until today when I decided to fully investigate why I couldn’t connect via RDP.     First a thank you to John Ross (@johnrossjr), Christina Wheeler (@cwheeler76) and Clayton Cobb (@warrtalon) for various suggestions while I was researching tonight.  As it turns out I had not 1, not 2, but 3 items preventing me from using RDP.  Let’s dig into the requirements above. Allow RDP Connection     This item I had previously taken care of, but it bears repeating because by default Windows Server 2008 R2 does not allow RDP connections.  Change the setting from “Don’t allow…” to whichever “Allow connections…” setting suits your needs.  I chose the less secure option as this is just my dev laptop. Network Adapter Type     When I originally configured my VMs I configured each to use 2 network adapters: one using the physical ethernet adapter for internet use and a virtual private adapter for communication between the VMs.  The connection for the ethernet adapter is an "”External” adapter and thus doesn’t connect between the host and guest.  The virtual private adapter allowed communication ONLY between the VMs and not to my host.  There is a third option “Internal” which allows communication between VMs as well as to the host.  After finding out this distinction I promptly created an Internal network adapter and assigned that to my VMs. Turn On Network Discovery     Seems like a pretty common sense thing, but in order to allow remote desktop connections the target computer must able to be found by the source computer (explained here.)  One of the settings that controls if a computer can be found on the network is aptly named Network Discovery.  By default Windows Server 2008 R2 turns Network Discovery off for security purposes.  To enable it open up the Network and Sharing Center.  Click “Change Advanced Sharing Settings” on the left.  On the following screen select “Turn on network discovery” for the currently used profile and click Save Settings.  You may notice though that your selection to turn on network discovery doesn’t save.  If this is the case then you most likely don’t have the supporting services running (as was my case.) Network Discovery Supporting Services     There are a total of 4 services (listed again below) that need to be running before you can turn on network discovery (explained here.)  The below images highlight these services.  In my guest VM I found that I had DNS Client already running while the other 3 were disabled.  I set them all to enabled and started the ones that were stopped.  After this change I returned to the Sharing settings screen and found that Network Discovery was turned on.  I’m not sure whether this was picking up my attempt to turn it on previously or if starting those services turned it on.  Either way the end result was a success. - DNS Client - Function Discovery Resource Publication - SSDP Discovery - UPnP Device Host Before and After Results     The first image is the smaller square shaped viewing window used by the Hyper-V native connection.  The second is the full-screen RDP connection in all its widescreen glory. Conclusion     Over the past few months I’ve found Hyper-V to be very useful for virtualizing my development environments, but I’ve also had a steep learning curve to get various items configured just right.  Allowing RDP connections to guest VMs was one area that I hadn’t been able to get right for the longest time.  Now that I resolved these issues I hope that others can avoid the pitfalls that I ran into.  If you know of any other items I left off feel free to let me know.        -Frog Out   Links Turning on Network Discovery http://sqlblog.com/blogs/john_paul_cook/archive/2009/08/15/remote-desktop-connection-on-windows-server-2008-r2.aspx Services required for Network Discovery http://social.technet.microsoft.com/Forums/en-US/winservergen/thread/2e1fea01-3f2b-4c46-a631-a8db34ed4f84

  • A Rose by Any Other Name..

    - by Geoff N. Hiten
    It is always a good start when you can steal a title line from one of the best writers in the English language.  Let’s hope I can make the rest of this post live up to the opening.  One recurring problem with SQL server is moving databases to new servers.  Client applications use a variety of ways to resolve SQL Server names, some of which are not changed easily <cough SharePoint /cough>.  If you happen to be using default instances on both the source and target SQL Server, then the solution is pretty simple.  You create (or bug the network admin until she creates) two DNS “A” records. One points the old name to the new IP address.  The other creates a new alias for the old server, since the original system name is now redirected.  Note this will redirect ALL traffic from the old server to the new server, including RDP and file share connection attempts.    Figure 1 – Microsoft DNS MMC Snap-In   Figure 2 – DNS New Host Dialog Box Both records are necessary so you can still access the old server via an alternate name. Server Role IP Address Name Alias Source 10.97.230.60 SQL01 SQL01_Old Target 10.97.230.80 SQL02 SQL01 Table 1 – Alias List If you or somebody set up connections via IP address, you deserve to have to go to each app and fix it by hand.  That is the only way to fix that particular foul-up. If have to deal with Named Instances either as a source or a target, then it gets more complicated.  The standard fix is to use the SQL Server Configuration Manager (or one of its earlier incarnations) to create a SQL client alias to redirect the connection.  This can be a pain installing and configuring the app on multiple client servers.  The good news is that SQL Server Configuration Manager AND all of its earlier versions simply write a few registry keys.  Extracting the keys into a .reg file makes centralized automated deployment a snap. If the client is a 32-bit system, you have to extract the native key.  If it is a 64-bit, you have to extract the native key and the WoW (32 bit on 64 bit host) key. First, pick a development system to create the actual registry key.  If you do this repeatedly, you can simply edit an existing registry file.  Create the entry using the SQL Configuration Manager.  You must use a 64-bit system to create the WoW key.  The following example redirects from a named instance “SQL01\SQLUtiluty” to a default instance on “SQL02”.   Figure 3 – SQL Server Configuration Manager - Native Figure 3 shows the native key listing. Figure 4 – SQL Server Configuration Manager – WoW If you think you don’t need the WoW key because your app is 64 it, think again.  SQL Server Management Server is a 32-bit app, as are most SQL test utilities.  Always create both keys for 64-bit target systems. Now that the keys exist, we can extract them into a .reg file. Fire up REGEDIT and browse to the following location:  HKLM\Software\Microsoft\MSSQLServer\Client\ConnectTo.  You can also search the registry for the string value of one of the server names (old or new). Right click on the “ConnectTo” label and choose “Export”.  Save with an appropriate name and location.  The resulting file should look something like this: Figure 5 – SQL01_Alias.reg Repeat the process with the location: HKLM\Software\Wow6432Node\Microsoft\MSSQLServer\Client\ConnectTo Note that if you have multiple alias entries, ALL of the entries will be exported.  In that case, you can edit the file and remove the extra aliases. You can edit the files together into a single file.  Just leave a blank line between new keys like this: Figure 6 – SQL01_Alias_All.reg Of course if you have an automatic way to deploy, it makes sense to have an automatic way to Un-deploy.  To delete a registry key, simply edit the .reg file and replace the target with a “-“ sign like so. Figure 7 – SQL01_Alias_UNDO.reg Now we have the ability to move any database to any server without having to install or change any applications on any client server.  The whole process should be transparent to the applications, which makes planning and coordinating database moves a far simpler task.

  • Running a Mongo Replica Set on Azure VM Roles

    - by Elton Stoneman
    Originally posted on: http://geekswithblogs.net/EltonStoneman/archive/2013/10/15/running-a-mongo-replica-set-on-azure-vm-roles.aspxSetting up a MongoDB Replica Set with a bunch of Azure VMs is straightforward stuff. Here’s a step-by-step which gets you from 0 to fully-redundant 3-node document database in about 30 minutes (most of which will be spent waiting for VMs to fire up). First, create yourself 3 VM roles, which is the minimum number of nodes you need for high availability. You can use any OS that Mongo supports. This guide uses Windows but the only difference will be the mechanism for starting the Mongo service when the VM starts (Windows Service, daemon etc.) While the VMs are provisioning, download and install Mongo locally, so you can set up the replica set with the Mongo shell. We’ll create our replica set from scratch, doing one machine at a time (if you have a single node you want to upgrade to a replica set, it’s the same from step 3 onwards): 1. Setup Mongo Log into the first node, download mongo and unzip it to C:. Rename the folder to remove the version – so you have c:\MongoDB\bin etc. – and create a new folder for the logs, c:\MongoDB\logs. 2. Setup your data disk When you initialize a node in a replica set, Mongo pre-allocates a whole chunk of storage to use for data replication. It will use up to 5% of your data disk, so if you use a Windows VM image with a defsault 120Gb disk and host your data on C:, then Mongo will allocate 6Gb for replication. And that takes a while. Instead you can create yourself a new partition by shrinking down the C: drive in Computer Management, by say 10Gb, and then creating a new logical disk for your data from that spare 10Gb, which will be allocated as E:. Create a new folder, e:\data. 3. Start Mongo When that’s done, start a command line, point to the mongo binaries folder, install Mongo as a Windows Service, running in replica set mode, and start the service: cd c:\mongodb\bin mongod -logpath c:\mongodb\logs\mongod.log -dbpath e:\data -replSet TheReplicaSet –install net start mongodb 4. Open the ports Mongo uses port 27017 by default, so you need to allow access in the machine and in Azure. In the VM, open Windows Firewall and create a new inbound rule to allow access via port 27017. Then in the Azure Management Console for the VM role, under the Configure tab add a new rule, again to allow port 27017. 5. Initialise the replica set Start up your local mongo shell, connecting to your Azure VM, and initiate the replica set: c:\mongodb\bin\mongo sc-xyz-db1.cloudapp.net rs.initiate() This is the bit where the new node (at this point the only node) allocates its replication files, so if your data disk is large, this can take a long time (if you’re using the default C: drive with 120Gb, it may take so long that rs.initiate() never responds. If you’re sat waiting more than 20 minutes, start another instance of the mongo shell pointing to the same machine to check on it). Run rs.conf() and you should see one node configured. 6. Fix the host name for the primary – *don’t miss this one* For the first node in the replica set, Mongo on Windows doesn’t populate the full machine name. Run rs.conf() and the name of the primary is sc-xyz-db1, which isn’t accessible to the outside world. The replica set configuration needs the full DNS name of every node, so you need to manually rename it in your shell, which you can do like this: cfg = rs.conf() cfg.members[0].host = ‘sc-xyz-db1.cloudapp.net:27017’ rs.reconfig(cfg) When that returns, rs.conf() will have your full DNS name for the primary, and the other nodes will be able to connect. At this point you have a working database, so you can start adding documents, but there’s no replication yet. 7. Add more nodes For the next two VMs, follow steps 1 through to 4, which will give you a working Mongo database on each node, which you can add to the replica set from the shell with rs.add(), using the full DNS name of the new node and the port you’re using: rs.add(‘sc-xyz-db2.cloudapp.net:27017’) Run rs.status() and you’ll see your new node in STARTUP2 state, which means its initializing and replicating from the PRIMARY. Repeat for your third node: rs.add(‘sc-xyz-db3.cloudapp.net:27017’) When all nodes are finished initializing, you will have a PRIMARY and two SECONDARY nodes showing in rs.status(). Now you have high availability, so you can happily stop db1, and one of the other nodes will become the PRIMARY with no loss of data or service. Note – the process for AWS EC2 is exactly the same, but with one important difference. On the Azure Windows Server 2012 base image, the MongoDB release for 64-bit 2008R2+ works fine, but on the base 2012 AMI that release keeps failing with a UAC permission error. The standard 64-bit release is fine, but it lacks some optimizations that are in the 2008R2+ version.

  • From Bluehost to WP Engine, My WordPress Story

    - by thatjeffsmith
    This is probably the longest blog post I’ve written in a LONG time. And if you’re used to coming here for the Oracle stuff, this post is not about that. It’s about my blog, and the stuff under the hood that makes it run, AKA WordPress. If you want to skip to the juicy stuff, then use these shortcuts: My Site Slowed Down How I Moved to WP Engine How WP Engine ‘Hooked’ Me Why WP Engine? I started thatJeffSmith.com on May 28th, 2010. I had been already been blogging for several years, but a couple of really smart people I respected (Andy, Brent – thanks again!) suggested that I take ownership of my content and begin building my personal brand. I thought that was a good idea, and so I signed up for service with bluehost. Bluehost makes setting up a WordPress site very, very easy. And, they continued to be easy to work with for the past 2 years. I would even recommend them to anyone looking to host their own WordPress install/site. For $83.40, I purchased a year’s worth of service and my domain name registration – a very good value. And then last year I paid $107.40 for another year’s services. And when that year expired I paid another $190.80 for an additional two year’s service in advance. I had been up to that point, getting my money’s worth. And then, just a few weeks ago… My Site Slowed to a Crawl That spike was from an April Fool's Day Post, I think Why? Well, when I first started blogging, I had the same problem that most beginner bloggers have – not many readers. In my first year of blogging, I think the highest number of readers on a single day was about 125. I remember that day as I was very excited to break 100! Bluehost was very reliable, serving up my content with maybe a total of 3-4 outages in the past 2 years. Support was usually very prompt with answers and solutions, and I love their ‘Chat now’ technology – much nicer than message boards only or pay-to-talk phone support. In the past 6 months however, I noticed a couple of things: daily traffic was increasing – woohoo! my service was experiencing severe CPU throttling – doh! To be honest, I wasn’t aware the throttling was occuring, but I did know that the response time of my blog was starting to lag. Average load times were approaching 20-30 seconds. Not good when good sites are loading in 5 seconds or less. And just this past week, in getting ready to launch a new website for work that sucked in an RSS feed from my blog, the new page was left waiting for more than a minute. Not good! In fact my boss asked, why aren’t you blogging on Blogger? Ugh. I tried a few things to fix the problem: I paid for a premium WordPress theme – Themify’s Grido (thanks to @SQLRockstar for the heads-up) I installed a couple of WP caching plugins I read every WP optimization blog post I could get my greedy little eyes on However, at the same time I was also getting addicted to WordPress bloggers talking about all the cool things you could do with your blog. As a result I had at one point about 30 different plugins installed. WordPress runs on MySQL, and certain queries running via these plugins were starving for CPU. Plugins that would be called every page load meant that as more people clicked on my site, the more CPU I needed. I’m not stupid, so I eventually figured out that maybe less plugins was better, and was able to go down to just 20. But still, the site was running like a dog. CPU Throttling, makes MySQL wait to run a query Bluehost runs shared servers. Your site runs on the same box that several hundred (or thousand?) other services are running on. If you take more CPU than they think you should have, they will limit your service by making you stand in line for CPU, AKA ‘throttling.’ This is not bad. This business model allows them to serve many, many users for a very fair price. It works great until, well, until it doesn’t. I noticed in the last week that for every minute of service, I was being throttled between 60 and 300 seconds. If there were 5 MySQL processes running, then every single one of them were being held in check. The blog visitor notice this as their page requests would take a minute or more to be answered. Bluehost unfortunately doesn’t offer dedicated server hosting, so there was no real upgrade path for me follow and remain one of their customers. So what was I to do? Uninstall every plugin and hope the site sped up? Ask for people to take turns on my blog? I decided to spend my way out of the problem. I signed up for service with WP Engine and moved ThatJeffSmith.com The first 2 months are free, and after that it’s about $29/month to run my site on their system. My math tells me that’s a good bit more expensive than what Bluehost was charging me – to the tune of about 300% more a month. Oh, and I should just say that my blog is a personal blog even though I talk about work stuff here. I don’t get paid for blogging, I don’t sell ads, and I don’t expense the service fees – this is my personal passion. So is it worth it? In the first 4 days, it seems to be totally worth it. Load times have gone from 20-30 seconds to less than 5 seconds. A few folks have told me via Twitter that they notice faster page loads. I anticipate this will indirectly lead to more traffic as Google penalizes you in search results if your site is too slow, and of course some folks won’t even bother waiting more than 5-10 seconds. I noticed right away that writing posts, uploading pictures, and just using the WordPress dashboard in general was much more responsive. So writing is less of a chore now, which means I won’t have a good reason not to write How I Moved to WP Engine I signed up for the service and registered my domain. I then took a full export of my ‘old’ site by doing a FTP GET of all my files, then did a MySQL database backup, exported my WordPress Theme settings to a .zip file, and then finally used the WordPress ‘Export’ feature. I then used the WordPress ‘Import’ on the new site to load up my posts. Then I uploaded the theme .zip package from Themify. Then I FTP’d the ‘wp-content’ directory up to my new server using SFTP (WP Engine only supports secure FTP – good on them!) Using a temporary URL to see my new site, I was able to confirm that everything looked mostly OK – I’ll detail the challenges and issues of fixing the content next – but then it was time to ‘flip the switch.’ I updated the IP address that the DNS lookup tables use to route traffic to my new server. In a matter of minutes the DNS servers around the world were updated and it was time to see the new site! But It Was ‘Broken’ I had never moved a website before, and in my rush to update the DNS, I had changed the records without really finding out what I was supposed to do first. After re-reading the directions provided by WP Engine and following the guidance of their support engineer, I realized I had needed to set the CNAME (Alias) ‘www’ record to point to a different URL than the ‘www.thatjeffsmith.com’ entry I had set. Once corrected the site was up and running in less than a minute. Then It Was Only Mostly Broken Many of my plugins weren’t working. Apparently just ftp’ing the wp-content directory up wasn’t the proper way to re-install the plugin. I suspect file permissions or file ownership wasn’t proper. Some plug-ins were working, many had their settings wiped to the defaults, and a few just didn’t work again. I had to delete the directory of the plug-in manually via SFTP, and then use the WP Dashboard to install it from scratch. And here was my first ‘lesson’ – don’t switch the DNS records until you’ve completely tested your new site. I wasn’t able to navigate the old WP console to review my plug-in settings. Thankfully I was able to use the Wayback Machine to reverse engineer some things, and of course most plug-ins aren’t that complicated to setup to begin with. An example of one that I had to redo from scratch is the ‘Twitter @Anywhere Plus’ plugin that I use to create the form that allows folks to tweet a post they enjoyed at the end of each story. How WP Engine ‘Hooked’ Me I actually signed up with another provider first. They ranked highly in Google searches and a few Tweeps recommended them to me. But hours after signing up and I still didn’t have sever reyady, I was ready to give up on them. They offered no chat or phone support – only mail and message boards. And the message boards were rife with posts about how the service had gone downhill in the past 6 months. To their credit, they did make it easy to cancel, although I did have to do so via email as their website ‘cancel’ button was non-existent. Within minutes of activating my WP Engine account I had received my welcome message and directions on how to get started. I was able to see my staged website right away. They also did something very cool before I even got started – they looked at my existing site and told me by how much they could improve its performance. The proof is in the web pudding. I like this for a few reasons, but primarily I liked their business model. It told me they knew what they were doing, and that they were willing to put their money where their mouth was. This was further evident by their 60-day money back guarantee. And if I understand it correctly, they don’t even take your money until after that 60 day period is over. After a day, I was welcomed by the WP Engine social media team, and was given the opportunity to subscribe to their newsletter and follow their account on Twitter. I noticed their Twitter team is sure to post regular WordPress tips several times a day. It’s not just an account that’s setup for the sake of having a Twitter presence. These little things add up and give me confidence in my decision to choose them as my hosting partner. ‘Partner’ – that’s a lot nicer word than just ‘service provider,’ isn’t it? Oh, and they offered me a t-shirt. Don’t ever doubt the power of a ‘free’ t-shirt! How awesome is this e-mail, from a customer perspective? I wasn’t really expecting any of this. Exceeding expectations before I have even handed over a single dollar seems like a pretty good business plan. This is how you treat customers. Love them to death, and they reward you with loyalty. But Jeff, You Skipped a Piece Here, Why WP Engine? I found them on one of those ‘Top 10′ list posts, and pulled up their webpage. I noticed they offered a specialized service – they host WordPress installs, and that’s it. Their servers are tuned specifically for running WordPress. They had in bolded text, things like ‘INSANELY FAST. INFINITELY SCALABLE.’ and ‘LIGHTNING SPEED.’ And then they offered insurance against hackers and they took care of automatic backups and restores. The only drawbacks I have noticed so far relate to plugins I used that have been ‘blacklisted.’ In order to guarantee that ‘lightning’ speed, they have banned the use of the CPU-suckiest plugins. One of those is the ‘Related Posts’ plugin. So if you are a subscriber and are reading this in your email, you’ll notice there’s no links back to my blog to continue reading other related stories. Since that referral traffic is very small single-digit for my site, I decided that I’m OK with that. I’d rather have the warp-speed page loads. Again, I think that will lead to higher traffic down the road. In 50+ days I will need to decide if WP Engine is a permanent solution. I’ll be sure to update this post when that time comes and let y’all know how it turns out.

  • IP Address Lookup in VB.net (XP vs Windows 7)

    - by TheHockeyGeek
    Currently I use the following code to retrieve the IP address of the local workstation... strIPAddress = System.Net.Dns.GetHostEntry(strComputerName).AddressList(0).ToString() This is fine for the Windows XP workstations. However, in Vista and Windows 7, this returns the IPv6 address which is not used at all. Is there a method of setting this to work so it always returns the IPv4 address regardless of platform? I know I can increment the AddressList value to 1 and get the correct IP in Windows 7. The bad part is that this requires going through the motions of identifying the OS and choosing one or the other. The must be some way of specifying IPv4 only. Perhaps getting a result from DNS on the network rather than the workstation itself?

    I'll admit I'm not very adept at key verification. What I have is a script that downloads messages from a POP3 server, and I'm attempting to verify the DKIM signatures in PHP. I've already figured out the body hash (bh) validation check, but I can't figure out the header validation. http://www.dkim.org/specs/rfc4871-dkimbase.html#rfc.section.6.1.3 Below is an example of my message headers. I've been able to use the Mail::DKIM package to validate the signature in Perl, so I know it's good. I just can't seem to figure out the instructions in the RFC and translate them into PHP code. DomainKey-Signature: q=dns; a=rsa-sha1; c=nofws; s=angrychimp-1.bh; d=angrychimp.net; h=From:X-Outgoing; b=RVkenibHQ7GwO5Y3tun2CNn5wSnooBSXPHA1Kmxsw6miJDnVp4XKmA9cUELwftf9 nGiRCd3rLc6eswAcVyNhQ6mRSsF55OkGJgDNHiwte/pP5Z47Lo/fd6m7rfCnYxq3 DKIM-Signature: v=1; a=rsa-sha1; d=angrychimp.net; s=angrychimp-1.bh; c=relaxed/simple; q=dns/txt; [email protected]; t=1268436255; h=From:Subject:X-Outgoing:Date; bh=gqhC2GEWbg1t7T3IfGMUKzt1NCc=; b=ZmeavryIfp5jNDIwbpifsy1UcavMnMwRL6Fy6axocQFDOBd2KjnjXpCkHxs6yBZn Wu+UCFeAP+1xwN80JW+4yOdAiK5+6IS8fiVa7TxdkFDKa0AhmJ1DTHXIlPjGE4n5; To: [email protected] Message-ID: From: DKIM Tester Reply-To: [email protected] Subject: Automated DKIM Testing (angrychimp.net) X-Outgoing: dhaka Date: Fri, 12 Mar 2010 15:24:15 -0800 Content-Type: text/plain; charset=iso-8859-1 Content-Transfer-Encoding: quoted-printable Content-Disposition: inline MIME-Version: 1.0 Return-Path: [email protected] X-OriginalArrivalTime: 12 Mar 2010 23:25:50.0326 (UTC) FILETIME=[5A0ED160:01CAC23B] I can extract the public key from my DNS just fine, and I believe I'm canonicalizing the headers correctly, but I just can't get the signature validated. I don't think I'm preparing my key or computing the signature validation correctly. Is this something that's possible (do I need pear extensions or something?) or is manually validating a DKIM signature in PHP just not feasible?

  • client ip address in ASP.NET (.asmx) webservices

    - by Zain Shaikh
    I am using ASP.Net (.asmx) web services with Silverlight. since there is no way to find client ip address in Silverlight, therefore I had to log this on service end. these are some methods I have tried: Request.ServerVariables(”REMOTE_HOST”) HttpContext.Current.Request.ServerVariables["REMOTE_ADDR"] HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"]; Request.UserHostAddress() Request.UserHostName() string strHostName = System.Net.Dns.GetHostName(); string clientIPAddress = System.Net.Dns.GetHostAddresses(strHostName).GetValue(0).ToString(); All the above methods work fine on my local system, but when I publish my service on production server. it starts giving errors. Error: Object reference not set to an instance of an object. StackTrace: at System.Web.Hosting.ISAPIWorkerRequestInProc.GetAdditionalServerVar(Int32 index) at System.Web.Hosting.ISAPIWorkerRequestInProc.GetServerVariable(String name) at System.Web.Hosting.ISAPIWorkerRequest.GetRemoteAddress() at System.Web.HttpRequest.get_UserHostAddress()

  • Outbound traffic being blocked for MIP/VIPped servers (Juniper SSG5)

    - by Mark S. Rasmussen
    As we've been having some problems with sporadic packet loss, I've been preparing a replacement router (also an SSG5) for our current Juniper SSG5. I've setup the new SSG5 identically to the old one. We have a /29 IP range with a single IP setup as a MIP map to a server and two others being used for VIP maps. Each VIP/MIP is accompanied by relevant policies. Long story short - we tried connected the new SSG5 and some things were not working as they should. No problem, I just reconnected the old one. However, some things are still broken, even when I reconnected the old one. I fear I may have inadvertently changed some settings while browsing through old settings in my attempt to reconfigure the new SSG5 unit. All inbound traffic seems to work as expected. However, the 192.168.2.202 server can't initiate any outbound connections. It works perfectly on the local network, but any pings or DNS lookups to external IP's fail. The MIP & VIP map to it works perfectly - I can access it through HTTP and RDP without issues. Any tips on what to debug, or where I've messed up my config? I've attached the full config here (with anonymized IPs): set clock timezone 1 set vrouter trust-vr sharable set vrouter "untrust-vr" exit set vrouter "trust-vr" unset auto-route-export exit set

  • Packing a long binary integer in Ruby

  • What to filter when providing very limited open WiFi to a small conference or meeting?

    - by Tim Farley
    Executive Summary The basic question is: if you have a very limited bandwidth WiFi to provide Internet for a small meeting of only a day or two, how do you set the filters on the router to avoid one or two users monopolizing all the available bandwidth? For folks who don't have the time to read the details below, I am NOT looking for any of these answers: Secure the router and only let a few trusted people use it Tell everyone to turn off unused services & generally police themselves Monitor the traffic with a sniffer and add filters as needed I am aware of all of that. None are appropriate for reasons that will become clear. ALSO NOTE: There is already a question concerning providing adequate WiFi at large (500 attendees) conferences here. This question concerns SMALL meetings of less than 200 people, typically with less than half that using the WiFi. Something that can be handled with a single home or small office router. Background I've used a 3G/4G router device to provide WiFi to small meetings in the past with some success. By small I mean single-room conferences or meetings on the order of a barcamp or Skepticamp or user group meeting. These meetings sometimes have technical attendees there, but not exclusively. Usually less than half to a third of the attendees will actually use the WiFi. Maximum meeting size I'm talking about is 100 to 200 people. I typically use a Cradlepoint MBR-1000 but many other devices exist, especially all-in-one units supplied by 3G and/or 4G vendors like Verizon, Sprint and Clear. These devices take a 3G or 4G internet connection and fan it out to multiple users using WiFi. One key aspect of providing net access this way is the limited bandwidth available over 3G/4G. Even with something like the Cradlepoint which can load-balance multiple radios, you are only going to achieve a few megabits of download speed and maybe a megabit or so of upload speed. That's a best case scenario. Often it is considerably slower. The goal in most of these meeting situations is to allow folks access to services like email, web, social media, chat services and so on. This is so they can live-blog or live-tweet the proceedings, or simply chat online or otherwise stay in touch (with both attendees and non-attendees) while the meeting proceeds. I would like to limit the services provided by the router to just those services that meet those needs. Problems In particular I have noticed a couple of scenarios where particular users end up abusing most of the bandwidth on the router, to the detriment of everyone. These boil into two areas: Intentional use. Folks looking at YouTube videos, downloading podcasts to their iPod, and otherwise using the bandwidth for things that really aren't appropriate in a meeting room where you should be paying attention to the speaker and/or interacting.At one meeting that we were live-streaming (over a separate, dedicated connection) via UStream, I noticed several folks in the room that had the UStream page up so they could interact with the meeting chat - apparently oblivious that they were wasting bandwidth streaming back video of something that was taking place right in front of them. Unintentional use. There are a variety of software utilities that will make extensive use of bandwidth in the background, that folks often have installed on their laptops and smartphones, perhaps without realizing.Examples: Peer to peer downloading programs such as Bittorrent that run in the background Automatic software update services. These are legion, as every major software vendor has their own, so one can easily have Microsoft, Apple, Mozilla, Adobe, Google and others all trying to download updates in the background. Security software that downloads new signatures such as anti-virus, anti-malware, etc. Backup software and other software that "syncs" in the background to cloud services. For some numbers on how much network bandwidth gets sucked up by these non-web, non-email type services, check out this recent Wired article. Apparently web, email and chat all together are less than one quarter of the Internet traffic now. If the numbers in that article are correct, by filtering out all the other stuff I should be able to increase the usefulness of the WiFi four-fold. Now, in some situations I've been able to control access using security on the router to limit it to a very small group of people (typically the organizers of the meeting). But that's not always appropriate. At an upcoming meeting I would like to run the WiFi without security and let anyone use it, because it happens at the meeting location the 4G coverage in my town is particularly excellent. In a recent test I got 10 Megabits down at the meeting site. The "tell people to police themselves" solution mentioned at top is not appropriate because of (a) a largely non-technical audience and (b) the unintentional nature of much of the usage as described above. The "run a sniffer and filter as needed" solution is not useful because these meetings typically only last a couple of days, often only one day, and have a very small volunteer staff. I don't have a person to dedicate to network monitoring, and by the time we got the rules tweaked completely the meeting will be over. What I've Got First thing, I figured I would use OpenDNS's domain filtering rules to filter out whole classes of sites. A number of video and peer-to-peer sites can be wiped out using this. (Yes, I am aware that filtering via DNS technically leaves the services accessible - remember, these are largely non-technical users attending a 2 day meeting. It's enough). I figured I would start with these selections in OpenDNS's UI: I figure I will probably also block DNS (port 53) to anything other than the router itself, so that folks can't bypass my DNS configuration. A savvy user could get around this, because I'm not going to put a lot of elaborate filters on the firewall, but I don't care too much. Because these meetings don't last very long, its probably not going to be worth the trouble. This should cover the bulk of the non-web traffic, i.e. peer-to-peer and video if that Wired article is correct. Please advise if you think there are severe limitations to the OpenDNS approach. What I Need Note that OpenDNS focuses on things that are "objectionable" in some context or another. Video, music, radio and peer-to-peer all get covered. I still need to cover a number of perfectly reasonable things that we just want to block because they aren't needed in a meeting. Most of these are utilities that upload or download legit things in the background. Specifically, I'd like to know port numbers or DNS names to filter in order to effectively disable the following services: Microsoft automatic updates Apple automatic updates Adobe automatic updates Google automatic updates Other major software update services Major virus/malware/security signature updates Major background backup services Other services that run in the background and can eat lots of bandwidth I also would like any other suggestions you might have that would be applicable. Sorry to be so verbose, but I find it helps to be very, very clear on questions of this nature, and I already have half a solution with the OpenDNS thing.

  • Async Socket Listener on separate thread - VB.net

    - by TheHockeyGeek
    I am trying to use the code from Microsoft for an Async Socket connection. It appears the listener runs in the main thread locking the GUI. I am new at both socket connections and multi-threading all at the same time. Having a hard time getting my mind wrapped around this all at once. The code used is at http://msdn.microsoft.com/en-us/library/fx6588te.aspx Using this example, how can I move the listener to its own thread? Public Shared Sub Main() ' Data buffer for incoming data. Dim bytes() As Byte = New [Byte](1023) {} ' Establish the local endpoint for the socket. Dim ipHostInfo As IPHostEntry = Dns.GetHostEntry(Dns.GetHostName()) Dim ipAddress As IPAddress = ipHostInfo.AddressList(1) Dim localEndPoint As New IPEndPoint(ipAddress, 11000) ' Create a TCP/IP socket. Dim listener As New Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp) ' Bind the socket to the local endpoint and listen for incoming connections. listener.Bind(localEndPoint) listener.Listen(100)
