• Windows Server 2003 IPSec Tunnel Connected, But Not Working (Possibly NAT/RRAS Related)

  - by Kevinoid

  Configuration I have setup a "raw" IPSec tunnel between a Windows Server 2003 (SBS) machine and a Netgear FVG318 according to the instructions in Microsoft KB816514. The configuration is as follows (using the same conventions as the article): NetA | SBS2003 | FVG318 | NetB 10.0.0.0/24 | 216.x.x.x | 69.y.y.y | 10.0.254.0/24 Both the Main Mode and Quick Mode Security Associations are successfully completed and appear in the IP Security Monitor. I am also able to ping the SBS2003 server on its private address from any computer on NetB. The Problem Any traffic sent from a computer on NetA to NetB, or from SBS2003 to NetB (excluding ICMP Ping responses), is sent out on the public network interface outside the IPSec tunnel (no encryption or header authentication, as if the tunnel were not there). Pings sent from a computer on NetB to a computer on NetA successfully reach computers on NetA, but the responses are silently discarded by SBS2003 (they do not go out in the clear and do not generate any encrypted traffic). Possible Solutions Incorrect Configuration I could have mistyped something, somewhere, or KB816514 could be incorrect in some way. I have tried very hard to eliminate the first option. Have re-created the configuration several times, tried tweaking and adjusting all the settings I could without success (most prevent the SA from being established). NAT/RRAS I have seen multiple posts elsewhere suggesting that this could be due to interaction between NAT and the IPSec filters. Possibly the NetA private addresses get rewritten to 216.x.x.x before being compared with the Quick Mode IPSec filters and don't get tunneled because of the mismatch. In fact, The Cable Guy article from June 2005 "TCP/IP Packet Processing Paths" suggests that this is the case, (see step 2 and 4 of the Transit Traffic path). If this is the case, is there a way to exclude NetA-NetB traffic from NAT? Any thoughts, ideas, suggestions, and/or comments are appreciated.

• pfsense 2.0 traffic priority - set full priority for single host

  - by Waxhead

  I have a network with several computers all on the same network and since I have very limited bandwidth I would like to prioritize traffic almost like a CPU scheduler prioritize processes. Example: Computer A: Used for webstuff: YouTube, downloads, news, emails etc. Computer B: Transferring files over HTTP Computer C: Transferring files over ftp, rsync whatever What I would like to do is to give A up to for example 90% of the available bandwidth IF A requires it. The leftovers (10%) is divided between B and C (5% each if both is busy) If A is not utilizing all bandwidth then of course B and C should share the full bandwidth (50% each as long as both are maxing out their bandwidth). All computers are on the same network (192.168.1.0 - 192.168.1-10 for example). Appreciate if anyone could shed some light on how I should set up my network to achieve this. To be honest I actually need a step by step guide on how I should set this up. Network setup: (ADSL modem configured in bridge mode (1500kbps/300kbps)) [ADSL modem (bridge)]<-[pfsense2.0]<-[switch]<-[Computer A,B,C...etc]

• How to safely move where itunes saves music/iphone apps/and meta data to another internal Drive?

  - by GingerLee

  In the past, when I have moved my itunes data from one computer to another, I usually just follow these steps: Copy the contents of two folders: %USERPROFILE%\Music\iTunes %USERPROFILE%\AppData\Roaming\Apple Computer 1) Install iTunes on the new computer, start it and close it (don't let it search for music). 2) Copy all the files in the above folders from old PC to new PC. 3) Start iTunes and authorize the new computer (and deauthorize old one). 4) Before syncing, update all iphone apps to current versions on both my iphone and in itunes. 5) The Sync. The above steps always work for me, and basically Itunes on my new PC works exactly as it did on the old PC. My Question: In the hopes of bybassing the above steps in the future, I would like to just have Itunes use another internal Drive that I use for file storage (e.g. D:/) as the path for the above two directory? Then if I move to new PC again, I could just setup itunes to use the correct path. Is that possible yet with minimal implications? If so how?

• Dosbox USB print Windows 8.1 64Bit

  - by eCronik

  Worked fine until I've upgraded to Windows 8.1 as well as made the mail programm working (had to get a windows live ID and have to type in a password now, when starting Windows). I did set the USB printer to lpt1 on the local Windows 8 computer and another XP computer via LAN to lpt2 the same way with the same printer on the Windows 8 computer. But now it doesn't work anymore from the Win8 one (where the printer is plugged via USB). Tried already deleting lpt2: on the XP one, as well as lpt1 on the Windows 8, resetted it. Not working... :-( I tried also net use lpt1: \server\printer password "\user:Ute Berger" /persistent:yes of course with the correct server and shared printer name as well as net use \server\printer "\user:Ute Berger" password /persistent:yes . This is the name displayed as a user now. But in C:\users it is named Benutzer1. Tried this one also. Nothing worked. What could be the problem here? What's strange is that when I type "net use lpt1:" on the XP, I get another error (67 - The networkname wasn't found) than trying something I didn't set up like lpt2 (2 - The system can't find the file). Could this be a possible problem as even if deleted something is left blocking on the Windows 8 computer? Please help me - I tried for hours today but all I've got was frustration... Regards Tim

• Problem with connecting two different networks

  - by tanascius

  I have two networks: 192.168.13.0/24 (blue) and 192.168.15.0/24 (green). Computer A is connected to the 13-net, only. Computer B has two interfaces, one in each network. There is third computer that acts like a router and connects the 13-net to the 15-net (only in this direction). Now, I'd like to ping 192.168.15.100 from computer A to B. Unfortunately there is never a reply. But when I use a hub instead of a switch it works. In my opinion the ping packet travels through the switch to the router (which is the default route/gateway for A). The router sends the packet back to the switch to B. Probably B receives it on its 15-net interface but answers with it's 15th interface? Is this possible? The problem is, that B may have only a gateway 192.168.13.50 - but I am not really sure of it (B is a embedded system with limited configuration possibilities). Can anyone explain what happens here? Thank you!

• Why just splitting an Ethernet cable does not work?

  - by Sin Jeong-hun

  I thought the Ethernet is logically one-line communication bus (for argument's sake, I am excluding hubs). All machines attached in the bus hears the same signals and the machines themselves try to avoid collisions by randomly backing off. http://computer.howstuffworks.com/ethernet6.htm If so, why splitting one Ethernet line from my home router into two and connecting two computers would not work? Why do I have to add a switch to it? *What the Internet said would not work. [4 port home router] ------[one Ethernet cable]-----[simple splitter]======[two computers] *What the Internet said I should do [4 port home router] ------[one Ethernet cable]-----[switch]======[two computers] Is this because of the signal degradation (reduced electric current)? Thank you for all the answers! The reason why I did not just use the two ports of my home router is... The 4-port gigabit router is in my room and I had put a computer in another room (also my room, though). Since wired network is far more reliable and secure, I had bought a long Ethernet cable and and connected the computer to the router. Now I was thinking about adding another computer to that room. I could buy another long Ethernet cable, but then there will be two cables between the rooms. The one line already is a minor annoyance, so I thought if I could share the one line between the two computers in that room. A switch would work, but it requires power and is a little bit pricey. That is why I wondered why it would not work to simply split the physical Ethernet cable. Apparently I do not completely understand how Ethernet and a switch work. I just have some bit of knowledge I heard in my college class.

• Why is my Toshiba Satellite L675D laptop not connecting to my HD TV using an HDMI cord?

  - by Akasha Eyre

  I'm having a problem connecting my Toshiba Satellite L675 laptop to my Samsung HD TV. I've done it before using an HDMI cord but now, for some odd reason, it's not connecting at all. My computer screen before would go completely black for a second & then come back & (with it being attached to the TV with the HDMI cord & it being on the proper channel) it would make a sound, come on & work beautifully. Now, I try hooking it up & it doesn't do anything. No black screen, no sound. The TV screen just says there's no connection & that I need to check out the power source. I'm still checking around, trying to find out if there's a virus in my computer (since my dad & I have the same computer & he can connect his to the TV with no problems), or if I deleted something that had to do with the connection. I've tried turning my computer off & letting it sit for a while, I've tried checking out other websites & have come up with nothing.

• How to recover Windows Password without reinstalling if you forgot Windows password?

  - by user38908

  Usually, we can recover Windows admin password in two traditional ways. The first is to change Windows password with another admin account; the second is to recover the previous password with the windows password reset disk that had been created before you forgot the password. Take Windows XP for example, 1 At the Windows XP login prompt when the password is entered incorrectly click the reset button in the login failed window. 2 Insert the password reset diskette into the computer and click Next. 3 If the correct diskette Windows XP will open a window prompting for the new password you wish to use. However, we offen ignore the important of security until we have been locked out of computer. Fortunately, there is still the last way that can unlock your computer without reinstalling - erase Windows password with Windows password reset CD, which can recover admin password for Windows 7/XP/Vista/NT/2000/2003.... Take Windows Password unlocker for example, followings are the steps to create the reset CD 1.Download Windows Password Unlocker from Password Unlocker Official site 2.Decompress the Windows password unlocker and note that there is an .ISO image file. Burn the image file onto an blank CD with the burner freely supported by Password Unlocker. 3.Insert the newly created CD into the locked computer and re-boot it from the CD drive. 4.After launched the CD, a window pop up with all your account names(if you have several accounts) select one of the accounts that you have forgotten its password to reset it. Just one press, this software can remove Windows password instantly.

• Can I install windows on an SSD and access data from my old windows HDD?

  - by nzifnab

  I purchased new computer components, switching my hardware from AMD and Radeon to Intel and Nvidia. I kept components from my old computer like the powersupply and two HDDs. Everything appeared to install correctly and the system booted into the BIOS just fine (after a brief snafu with the CPU fan). My goal was to use the two harddrives and just be able to turn on the computer and load up my old windows install with all the files, programs, and documents. I expected to have to call Microsoft to re-register the windows install for the new hardware (since I had to do that last time I upgraded w/ the same windows version). When the computer attempts to boot into windows it briefly flashes a bluescreen and then restarts. System recovery gives a message something like "BadDriver Failover" something something. I assume this is because it's trying to use amd drivers for an intel chipset (or something...?) and I've been as-yet unsuccessful in getting it to boot into my old windows partition. SO! I decided eff it, maybe I'll go visit my nearest Micro Center and buy a 200 GB SSD, install windows onto that, and then... be able to access just the contents of both of my other harddrives? I don't intend on running any of the programs but there were some saved files I would like to salvage from the 500 GB harddrive, The 1.5 TB harddrive only had files on it, no OS or applications so I'd also expect to still be able to access it. Is this possible? Can I install the SSD and only format/install windows onto it and still access the contents from my two transferred-over drives?

• Internet compression proxy for low speed broadband?

  - by user23150

  I live in a rural location, using high-latency wireless off a local ISP's tower. My speed tests vary day to day, but I can get around 1Mb up/down. The problem is, I work with large files, uploading and downloading (HD videos, development software, etc.). It can be painful to wait sometimes. Plus I do some side contract game development, and it can be very difficult to playtest with other developers (200ms ping is a good day for me). Now, obviously it's not going to be easy to solve the latency problem without different wireless hardware. But speedwise, I am wondering if I can use some kind of compression technology on a proxy. For instance, my work computer has full access to a 26Mb down, 10Mb up connection, that is totally unused at night and the weekends. If I could run some kind of compression technology on our server, and use it as a proxy to route to my home computer, I could stand to gain some major speed. I realize that by bogging down a system with compression, I could potentially lose whatever speed gain I had. But the proxy server is a quad core xeon, and the receiving computer is a pretty decent i7 computer, so that shouldn't be a concern. I found http://toonel.net/ but it seems more geared toward very slow narrowband users, like dial-up. Plus, I would prefer to just be able to point my browser to a proxy server, rather then install software on my client machine. EDIT I thought about my question a little more, and realize I am going to need to install software on my client in order to decompress, and possible compress (for uploading). That's not a huge deal.

• Lost user account for Windows Vista

  - by annelie

  Hello, I'm trying to help a friend who's lost her user account in Vista. I know there's supposed to be a way you can boot the computer from the vista installation disc and create an admin account you can later login with, but her installation disc is in Australia and her laptop in London. Is there any other way to get in? Or would it be better to try and access just the harddrive? She's mainly concerned with getting all her data off it. As for how she lost the account, I'll let her explain in her words. :) My computer basically got some virus and now is up sh*t creek. it told me i had this cryptic thingy majiggy was missing and then this fake virus told me i needed to scan my computer. SO i tried to do malware thing but it kept shutting my computer down. ANYWAY...now its it will only open up with 'launch startup repair' and has got rid of my settings for logging in and wants me to be 'other user' which i have no password or username for'...so basically im stuffed. This is Windows Vista by the way. Thanks, Annelie

• Transparent, unicode X terminal not tied to a Desktop Environment?

  - by jamuraa

  I've been looking for this for a while now and I just haven't been able to find one. The last few that I used were: aterm - this one was fast and had good transparency support, but it doesn't support Unicode at all as far as I can tell. The dependency graph is also reasonable. gnome-terminal - was good, and had good transparency support plus unicode, but it pulls in about everything in gnome, and I don't use anything else in gnome. It was also somewhat slow (noticable lag in updating at times) and wouldn't use fonts that I wanted. Eterm - same thing as aterm, good dependencies and transparency but no unicode. Does anyone have suggestions, or will I be stuck with gnome-terminal's dependencies and slowness?

• Incorrect Internal DNS Resolution

  - by user167016

  I'm having a DNS issue. Server 2008 R2. The first clue was that after being off the network for a month, I could no longer Remote Desktop into my workstation by name, it wouldn't find it. Both via VPN and internally. But if I connect using its IP, that works. Now I notice in the server's Share and Storage Management, in Manage Sessions, it's displaying the incorrect computer name for some users. So I try, for one example: Ping -a 192.168.16.81 Pinging BOBS_COMPUTER.ourdomain.local [192.168.16.81] with 32 bytes of data: - replies all successful Then I try Ping RICHARDS_COMPUTER Pinging RICHARDS_COMPUTER.ourdomain.local [192.168.16.81] with 32 bytes of data: -all replies successful In DHCP, .81 belongs to RICHARDS_COMPUTER I did try flushdns. Not sure if this is related, apologies if it's not, but when I try to connect, I also get prompted: "The identity of the remote computer cannot be verified. Do you want to connect anyway? The remote computer could not be authenticated due to problems with its security certificate. It may be unsafe to proceed.." It then lists the correct name as the name in the certificate from the remote computer, but claims that the certificate is not from a trusted authority. Any thoughts are most appreciated!

• Formatting a former RAID 0 drive through USB

  - by EXC

  I'll try to be as specific as possible here: I was using two Hitachi 2.5" 500 gb HDDs in my Gateway P-7805u laptop in a RAID 0 configuration. The array was causing the laptop to run extremely hot, however, so I removed them and deleted the RAID array through Intel Matrix HDD manager. I did a clean install of Windows 7 on the original 320 gb HDD that came with the laptop. I never did format the original RAID array HDDs before taking them out of the computer. Now, I am attempting to format the Hitachi 500 gb RAID array HDDs externally through a USB external enclosure. The external HDD drivers install on my clean install OS, but when I go into 'My Computer' there is no external drive available. I cannot format in CMD Prompt because my computer will not designate a drive letter to the external HDD. The drivers install and the HDD is recognized as a Hitachi external drive, but nothing seems to show up in my computer window. I need to know if there is a way to format these drives to NTFS externally.

• Is there any any merit to routinely restore a linux system, even if unnecessary?

  - by field_guy

  I do fieldwork with a number of computers running ubuntu performing critical tasks doing fieldwork. The computers are similarly configured with slight variations. Since we've had some configuration issues in the past, my boss is pressing for us to take an image of the installation on each computer, and restore each computer to that image before they are to go into the field. My preferred solution would be to write a common script that checks to ensure that the configuration of the system is correct and that the system is operational. If the computer has been verified, isn't restoring it to that configuration redundant? And are there any inherent problems with doing so? My reluctance stems from the fact that our software and configuration is subject to change in the field, but these changes must be made across all the computers. That means that when a change is made, all the restoration images have to be updated as well. The differences in the configuration of each of the computers live in /etc. In the event that restoration is required, I would prefer to keep a single image containing everything that is common to all machines, and have a snapshot of each computer's /etc directory to be used for restoring the state of that particular machine. What's the better approach?

• What are the pros of switching DNS names with a database server hardware upgrade?

  - by wilbbe01

  When we upgrade to new hardware at work we usually increment a number in the DNS name. For example. We have a server called database-2, that is slated to become database-3 in the coming days. I haven't been able to find a good reason why this is good behavior. To me the work of trying to catch all end user machines, as well as all servers dependent on the database server is far riskier than simply moving the database and ip/name with it to the new hardware. A little over a year ago we spent several months of requests coming in, as infrequent users began using software that needed to be updated to point to a new DNS name. I am struggling to find answers as to why this is a good practice. So the question. Why is using DNS names as a "server hardware version identifier" a good idea? What am I overlooking? Thanks much.

• Diagramming Software for a Developer/Designer

  - by Craig Walker

  For a long time I've been looking for a good diagramming/vector-based drawing program that meets my needs as a developer. I'd like to: Draw database diagrams Draw flow charts Draw object-modeling diagrams (UML being the standard) Draw other free-form diagrams (basically boxes & arrows with the occasional clipart) Draw mockups of user interfaces and web pages EDIT: I want good-looking electronic-format diagrams that I can show to 3rd parties, not just something for my own internal use. EDIT 2: I'm also looking for Windows software, although I'm toying with the idea of switching to Mac, so a really good Mac-only product might get me to switch. Basically I need a good vector graphic program (with decent grouping, connecting lines, and ideally auto-routing). I'd prefer a diagramming tool that can also be used for drawing (for the UI mockups) rather than a drawing tool that can also be used for diagrams. I've tried Visio on several occasions, and every time I've been disappointed. The interface always seems to get in my way at some point. It's pretty close to what I want, and the latest version (I got the trail from MS) seems to be better than previous ones in terms of usability, but I really don't want to plunk down that sort of cash for a mediocre product. I've tried Dia and Inkscape, and while initially promising and with the right price tag, I found both of them to be lacking in several ways (including some recurring bugs). I've toyed with getting Adobe Illustrator, but I've never used it before, and I have a feeling that it wouldn't handle the diagramming aspect very well, and I don't want to buy a copy just to find out it doesn't meet my needs. So far, the product that I've had the most success with is, sadly, OpenOffice Draw. It's free of course (which lowers my expectations and thus improves my view of it) and its usability is pretty good, but in the end I'd like something more suited to diagramming. I'm willing to spend real money (in the $500-$1K range) for a really good piece of software if it does everything I want it to. The front runner is of course Visio but I'm hoping for more. Does anybody have any recommendations? CONCLUSION: @dlamblin had the most informative post, but the part I gained the most from was his/her (and others) mention of OmniGraffle, not Gliffy. I gave Gliffy a try, and it seemed neet for occational use, but since it's a Flash app (note: not AJAX as dlamblin mentioned) it's still a bit of a pain to use (no keyboard shortcuts for copy/paste was pretty much a deal breaker for me). I also tried SmartDraw, but it had 3-strikes-you're-out against it: The trial period was only 7 days long. It used some nonstandard (and visually jarring) GUI widget toolkit for its UI. At the very least it makes me suspicious (how do I know it will actually work & support the standard Windows features?) It crashed on me early into my trial. OmniGraffle looks like exactly what I want... except that it's Mac-only (so I couldn't give it a try). However, it got good reviews from my Mac-owning coworker, and I hope to try it on a friend's Mac soon. If it's good enough then I might spring for a new MacBook.

• Are programmers bad testers?

  - by jhsowter

  I know this sounds a lot like other questions which have already being asked, but it is actually slightly different. It seems to be generally considered that programmers are not good at performing the role of testing an application. For example: Joel on Software - Top Five (Wrong) Reasons You Don't Have Testers (emphasis mine) Don't even think of trying to tell college CS graduates that they can come work for you, but "everyone has to do a stint in QA for a while before moving on to code". I've seen a lot of this. Programmers do not make good testers, and you'll lose a good programmer, who is a lot harder to replace. And in this question, one of the most popular answers says (again, my emphasis): Developers can be testers, but they shouldn't be testers. Developers tend to unintentionally/unconciously avoid to use the application in a way that might break it. That's because they wrote it and mostly test it in the way it should be used. So the question is are programmers bad at testing? What evidence or arguments are there to support this conclusion? Are programmers only bad at testing their own code? Is there any evidence to suggest that programmers are actually good at testing? What do I mean by "testing?" I do not mean unit testing or anything that is considered part of the methodology used by the software team to write software. I mean some kind of quality assurance method that is used after the code has been built and deployed to whatever that software team would call the "test environment."

• Why are data structures so important in interviews?

  - by Vamsi Emani

  I am a newbie into the corporate world recently graduated in computers. I am a java/groovy developer. I am a quick learner and I can learn new frameworks, APIs or even programming languages within considerably short amount of time. Albeit that, I must confess that I was not so strong in data structures when I graduated out of college. Through out the campus placements during my graduation, I've witnessed that most of the biggie tech companies like Amazon, Microsoft etc focused mainly on data structures. It appears as if data structures is the only thing that they expect from a graduate. Adding to this, I see that there is this general perspective that a good programmer is necessarily a one with good knowledge about data structures. To be honest, I felt bad about that. I write good code. I follow standard design patterns of coding, I do use data structures but at the superficial level as in java exposed APIs like ArrayLists, LinkedLists etc. But the companies usually focused on the intricate aspects of Data Structures like pointer based memory manipulation and time complexities. Probably because of my java-ish background, Back then, I understood code efficiency and logic only when talked in terms of Object Oriented Programming like Objects, instances, etc but I never drilled down into the level of bits and bytes. I did not want people to look down upon me for this knowledge deficit of mine in Data Structures. So really why all this emphasis on Data Structures? Does, Not having knowledge in Data Structures really effect one's career in programming? Or is the knowledge in this subject really a sufficient basis to differentiate a good and a bad programmer?

• HTML5 or Javascript game engine to develop a browser game

  - by Jack Duluoz

  I would like to start developing a MMO browser game, like Travian or Ogame, probably involving also a bit of more sophisticated graphical features such as players interacting in real time with a 2d map or something like that. My main doubt is what kind of development tools I should use: I've a good experience with PHP and MySQL for the server side and Javascript (and jQuery) regarding the client side. Coding everything from scratch would be of course really painful so I was wondering if I should use a javascript game engine or not. Are there (possibly free) game engine you would recommend? Are they good enough to develop a big game? Also, I saw a lot of HTML5 games popping up lately but I'm now sure if using HTML5 is a good idea or not. Would you recommend it? What are the pro and cons about using HTML5? If you'd recommend it, do you have any good links regarding game development with HTML5? (PS: I know that HTML5 and a Javascript engine are not mutually exclusive, I just didn't know how to formulate a proper title since English is not my main language. So, please, answer addressing HTML5 and a game engine pro and cons separately)

• What is the best way to evaluate new programmers?

  - by Rafael

  What is the best way to evaluate the best candidates to get a new job (talking merely in terms of programming skills)? In my company we have had a lot of bad experiences with people who have good grades but do not have real programming skills. Their skills are merely like code monkeys, without the ability to analyze the problems and find solutions. More things that I have to note: The education system in my country sucks--really sucks. The people that are good in this kind of job are good because they have talent for it or really try to learn on their own. The university / graduate /post-grad degree doesn't mean necessarily that you know exactly how to do the things. Certifications also mean nothing here because the people in charge of the certification course also don't have skills (or are in low paying jobs). We need really to get the good candidates that are flexible and don't have mechanical thinking (because this type of people by experience have a low performance). We are in a government institution and the people that are candidates don't necessarily come from outside, but we have the possibility to accept or not any candidates until we find the correct one. I hope I'm not sounding too aggressive in my question; and BTW I'm a programmer myself. edit: I figured out that asked something really complex here. I will un-toggle "the correct answer" only to let the discussion going fluent, without any bias.

• When too much encapsulation was reached

  - by Samuel

  Recently, I read a lot of gook articles about how to do a good encapsulation. And when I say "good encapsulation", I don't talk about hiding private fields with public properties; I talk about preventing users of your Api to do wrong things. Here is two good articles about this subject: http://blog.ploeh.dk/2011/05/24/PokayokeDesignFromSmellToFragrance.aspx http://lostechies.com/derickbailey/2011/03/28/encapsulation-youre-doing-it-wrong/ At my job, the majority a our applications are not destined to other programmers but rather to the customers. About 80% of the application code is at the top of the structure (Not used by other code). For this reason, there is probably no chance ever that this code will be used by other application. An example of encapsulation that prevent user to do wrong thing with your Api is to return an IEnumerable instead of IList when you don't want to give the ability to the user to add or remove items in the list. My question is: When encapsulation could be considered like too much of purism object oriented programming while keeping in mind that each hour of programming is charged to the customer? I want to do good code that is maintainable, easy to read and to use but when this is not a public Api (Used by other programmer), where could we put the line between perfect code and not so perfect code? Thank you.

• Upload to PPA succeeded but packages doesn't appear

  - by lorin

  I'm trying to upload packages to my PPA for the first time. I want to use the PPA for customized versions of the OpenStack Compute (nova) project, so I tried to do a test by uploading packages corresponding to the bexar release of this project (lp:nova/bexar), with a new version number and changelog entry. I signed the source packages using my OpenGPG key, which has been uploaded to the ubuntu keyserver: $ dch -v 2011.1-0ubuntu2-isi1 -D lucid "ISI bexar build #1" $ dpkg-buildpackage -s -rfakeroot -tc -D -k4C8A14AB When I tried to upload the files to the repository, it seemed to work (real email obscured): $ dput ppa:lorinh/ppa nova_2011.2~bzr663-1isi1_source.changes Checking signature on .changes gpg: Signature made Fri 11 Feb 2011 03:52:50 PM EST using RSA key ID 4C8A14AB gpg: Good signature from "Lorin Hochstein <lorin@...>" Good signature on /home/lorin/packaging/nova_2011.2~bzr663-1isi1_source.changes.

Uploading nova_2011.2~bzr663-1isi1_source.changes: done. However, the packages aren't listed on my PPA page. If I try to upload again, I get the error: $ dput ppa:lorinh/ppa nova_2011.2~bzr663-1isi1_source.changes Package has already been uploaded to ppa on ppa.launchpad.net Nothing more to do for nova_2011.2~bzr663-1isi1_source.changes Am I supposed to do something next? How do I track down what wrong? As of this writing, it's been a day and a half since I've done the upload.
