• Ubuntu 12.04 Freezes w/ Ethernet Unplugged + Wireless Drops (Acer Aspire 5516)

  - by Grand Master T

  Ubuntu 12.04-12.10 32/64 freezes or won't boot if the Ethernet cable is unplugged and will not hold a wireless connection. Here is my scenario... Laptop: Acer Aspire 5516 Wireless card: Broadcom BCM4312 Ubuntu 12.04 32/64 Issues Unity 3d won't load without the Ethernet cable plugged in. If I let it load with Ethernet plugged in, it will freeze once I disconnect the cable. Unity 2d will load without the Ethernet cable plugged. In Unity 2d, wireless cannot hold a connection. I can connect to a Wireless network, but when I try to use it (i.e. open a browser), it disconnects. I can reconnect by disabling wireless (uncheck Enable Wireless), re-enable wireless, and reconnect. But, it will disconnect again once I start using it. Ubuntu 12.10 Issues Since 12.10 only gives me the option to load 3d (I assume), I experience the same thing as the first issue in 12.04. Attempted Solutions Enable networking/LAN in BIOS Set LAN first in boot priority in BIOS Remove STA wireless driver (bcmwl-kernel-source) and install b43 low power driver (firmware-b43-lpphy-installer). Remove default Network Manager and install Wicd. So far, I have had no luck with fixing this issue. Does anyone have any further suggestions?

• Can't connect to Wireless Network - Ubuntu 12.04 LTS & Sabrent A111N USB Dongle

  - by Ohgodwhy

  I've been trying to connect to this network for quite some time. I can't directly connect to the router with a Wire, but can access the Router with other wireless devices without any issues. I had previously tried several other Wifi nic's but none of them would load properly. Today, i went and bought a new (supported) Sabrent A111N USB Dongle, which said explicitly that it works with Linux 2.4 +. I popped the Dongle in, and low-and-behold it immediately said that there were Available Wireless Connections. I selected my connection and tried to connect, but it just loops constantly while saying Wireless Disconnected then attempts to connect again over and over. ifconfig and iwconfig both show my device in a ready and working state. However, iwlist wlan0 scan says that there are no results found. I don't get it... At one point, I could see the CPU in the DHCP client list under the router, but it doesn't fully make the connection (something about a timeout?). Any help would be appreciated.

• 12.10 no audio via hdmi and video speeds up

  - by jackson

  I have a laptop with an ati radeon 4200, on 12.04 everything worked fine, since upgrading to 12.10 I cannot get sound over the hdmi. When I switch to hdmi audio the video speeds up to about 2x. I can use the speakers in my laptop and watch video via hdmi with no problems. Things I have tried: Various tutorials to install the AMD/ATI drivers, all of which resulted in low graphics mode. Checked that everything is properly set in alsamixer, the sound utility and - installed pavucontrol and checked everything in there. Verified the output from cat /proc/asound/cards looks normal When I initially upgraded there was a plethora of problems which I believe were due to the old proprietary driver still being used but not compatible, after a few hours trying to fix that I decided just to back up and do a fresh install which works great except for the above stated problem. Any help would be greatly appreciated!! Finally hopefully this hasn't already been answered, I have tried a few different searches on the boards and haven't come up with anything. $ aplay -l **** List of PLAYBACK Hardware Devices **** card 0: SB [HDA ATI SB], device 0: ALC269VB Analog [ALC269VB Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: HDMI [HDA ATI HDMI], device 3: HDMI 0 [HDMI 0] Subdevices: 0/1 Subdevice #0: subdevice #0

• Ubuntu does not recognize my built-in monitor.

  - by B3tturTh3nU

  I've recently discovered of a boot problem Ubuntu has with my laptop. I have successfully installed Ubuntu on two other computers, and I've never experienced this problem. What happens is, after the live boot CD loads, the screen goes completely blank. Although, I suspected that there was no problem booting, so I loaded with BIOS only, which worked perfectly fine. Of course, not being very proficient with this, I have no idea what needs to be done to fix the problem. I have switchable graphics cards(the ATI Mobility Radeon HD 5650, and some low-end Intel card), and an Intel i5 quad core processor. I was booting with the Ubuntu 10.10 64 bit desktop distribution. If there's any more information you need from me, please let me know. EDIT: I was able to look into this a bit more, thanks to one of the comments provided, and I have some new information. Ubuntu does seem to be able to recognize both of my graphics cards. The problem I found was that, in the Xorg.0 log, it mentions that there were "no screens found." I'm using a notebook, so the screen is built in. Does anyone know of a way to get Ubuntu to recognize the monitor?

• Remember way back when we had a free decompiler?

  - by Justin Jones

  I, like probably so many of the rest of you, was mortified when Reflector was sold to RedGate. I knew where it was going. Suddenly you had to install it instead of just download and run it. I had a deep down feeling that one of the most useful tools in my arsenal was about to become a corporate product and no longer belong to the world of free tools. Sure enough it did. For a while now I’ve limped by without my favorite decompiler. This was made a little easier by the fact that you can now debug into the .net framework, but I still missed Reflector. JetBrains, makers of the superawesome and well worth the cost ReSharper (no it’s not free) have made their own decompiler that is comparable with Reflector, and it’s free. It’s still a corporate product, and JetBrains isn’t exactly known for making free software, but for now we have an option back on the table until some other industrious developer makes the next Reflector. dotPeek can be downloaded here.  http://www.jetbrains.com/decompiler/

• Ubuntu 10.04 hung on unattended apt-get upgrade?

  - by hafichuk

  I'm looking into why our ubuntu web server hung this morning and see that there was some package upgrades a few hours prior to the problem. I was able to ssh into the system and get a snapshot from top: top - 08:13:54 up 210 days, 8:25, 2 users, load average: 433.30, 422.40, 375.70 Tasks: 1192 total, 381 running, 810 sleeping, 0 stopped, 1 zombie Cpu(s): 0.5%us, 6.1%sy, 0.0%ni, 93.4%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Mem: 49549772k total, 48518392k used, 1031380k free, 960152k buffers Swap: 11595768k total, 279368k used, 11316400k free, 39355664k cached This is a 16 processor system, so I would typically expect a load in the low teens. I tried to restart apache, which didn't work, and subsequently had to do a hard reboot to get it working again (which it is). One thing I found was that the server did an unattended package update. Is it possible that upgrading php or curl (which our web sites use) might have caused apache to stop responding? Here is the snip from the unattended-upgrades.log from this morning: 2012-09-18 06:48:30,076 INFO Initial blacklisted packages: 2012-09-18 06:48:30,076 INFO Starting unattended upgrades script 2012-09-18 06:48:30,077 INFO Allowed origins are: ["['Ubuntu', 'lucid-security']"] 2012-09-18 06:49:37,017 INFO Packages that are upgraded: gnupg-curl php5-dev linux-server dhcp3-common linux-libc-dev php5-curl gpgv gnupg linux-headers-server linux-image-server php5 php5-mysql php-pear php5-cli php5-common libapache2-mod-php5 dhcp3-client 2012-09-18 06:49:37,018 INFO Writing dpkg log to '/var/log/unattended-upgrades/unattended-upgrades-dpkg_2012-09-18_06:49:37.017909.log'

• Why is the use of abstractions (such as LINQ) so taboo?

  - by Matthew Patrick Cashatt

  I am an independent contractor and, as such, I interview 3-4 times a year for new gigs. I am in the midst of that cycle now and got turned down for an opportunity even though I felt like the interview went well. The same thing has happened to me a couple of times this year. Now, I am not a perfect guy and I don't expect to be a good fit for every organization. That said, my batting average is lower than usual so I politely asked my last interviewer for some constructive feedback, and he delivered! The main thing, according to the interviewer, was that I seemed to lean too much towards the use of abstractions (such as LINQ) rather than towards lower-level, organically grown algorithms. On the surface, this makes sense--in fact, it made the other rejections make sense too because I blabbed about LINQ in those interviews as well and it didn't seem that the interviewers knew much about LINQ (even though they were .NET guys). So now I am left with this question: If we are supposed to be "standing on the shoulders of giants" and using abstractions that are available to us (like LINQ), then why do some folks consider it so taboo? Doesn't it make sense to pull code "off the shelf" if it accomplishes the same goals without extra cost? It would seem to me that LINQ, even if it is an abstraction, is simply an abstraction of all the same algorithms one would write to accomplish exactly the same end. Only a performance test could tell you if your custom approach was better, but if something like LINQ met the requirements, why bother writing your own classes in the first place? I don't mean to focus on LINQ here. I am sure that the JAVA world has something comparable, I just would like to know why some folks get so uncomfortable with the idea of using an abstraction that they themselves did not write. UPDATE As Euphoric pointed out, there isn't anything comparable to LINQ in the Java world. So, if you are developing on the .NET stack, why not always try and make use of it? Is it possible that people just don't fully understand what it does?

• Any mobile-friendly Credit Card billing solutions for mobile sites similar to Bango?

  - by Programmer

  Are there any mobile-friendly Credit Card billing solutions for mobile sites similar to Bango? The advantages of Bango I have seen compared to regular Credit Card solutions that make it considerably "mobile-friendly" are: 1) It does not require the user to enter their full name and billing address to make a payment. The user is only required to enter their Credit Card number, expiration date, and CVC code (if they are in the U.S., they will also have to enter their Zip Code). That is significantly less input than is normally required for Credit Card payments, which is a big plus on small mobile key pads. After a user makes an initial Credit Card payment, their details are stored by Bango, and the next time the user needs to make a payment with the same Credit Card, they just have to click a single link and it processes the payment on their stored Credit Card. Needless to say, this is very convenient for mobile users as it is analogous to Direct Carrier Billing as far as the user is concerned since they won't need to input any details. The downside with Bango is that their fees are higher than others, all payments must be processed via their site and branding, there is a high minimum ($1.99) and a low maximum ($30) on how much you can charge users, and you need to pay a monthly fee on top of the high transaction costs. It is due to the downsides mentioned above that I am looking for an alternative solution that also does the advantages 1) and 2) above. Is there anything like that? I looked at JunglePay and they do neither 1) nor 2).

• Creating Gun objects with upgrades?

  - by zardon

  I have a series of guns in my game. I use the Gun class/object like this: (Just an example) @interface Gun : NSObject { NSString *name; // Six-shooter NSNumber *cost; NSNumber *clipPrice; // ie: 700 NSNumber *clipCapacity; // 6 NSNumber *ammoCapacity; // 6 NSNumber *damage; // 0-10 NSNumber *accuracy; // 0-10 NSNumber *fireRate; // 0-10 NSNumber *range; // 0-10 // Not sure if I have all the stats, but this is fine for now } Lets say I want to have 3 upgrades per gun. My problem is I am not sure how to do this. Examples: increase fire-rate increase range increase accuracy silencer double ammo capacity (ie: Drum) double clip capacity (ie: Taped magazine) Thus my question is, I'd like to implement an upgrade system to guns but I am not sure how to do it. Would there be an Upgrade object which is a child to the Gun class, or would it be seperate class altogether. Thanks for your time.

• Which approach is the most maintainable?

  - by 2rs2ts

  When creating a product which will inherently suffer from regression due to OS updates, which of these is the preferable approach when trying to reduce maintenance cost and the likelihood of needing refactoring, when considering the task of interpreting system state and settings for a lay user? Delegate the responsibility of interpreting the results of inspecting the system to the modules which perform these tasks, or, Separate the concerns of interpretation and inspection into two modules? The first obviously creates a blob in which a lot of code would be verbose, redundant, and hard to grok; the second creates a strong coupling in which the interpretation module essentially has to know what it expects from inspection routines and will have to adapt to changes to the OS just as much as the inspection will. I would normally choose the second option for the separation of concerns, foreseeing the possibility that inspection routines could be re-used, but a developer updating the product to deal with a new OS feature or something would have to not only write an inspection routine but also write an interpretation routine and link the two correctly - and it gets worse for a developer who has to change which inspection routines are used to get a certain system setting, or worse yet, has to fix an inspection routine which broke after an OS patch. I wonder, is it better to have to patch one package a lot or two packages, each somewhat less so?

• Sharing password-protected videos on social media

  - by PaulJ

  We are developing a site where users will be able to watch and download videos that they've recorded of themselves in a public event. The videos will be password protected, and will be available only to users who have paid for them at the event... ...But on the other hand, we also want users to share those videos on social media, since they will be an attractive publicity for our events. Having people log into our site with their password, download the video and then re-upload it to Youtube/Facebook will be too cumbersome, and I suspect that few users will be willing to do that. So the obvious alternative is to have one of those convenient "share" buttons, but the problem with that approach will be that: The video will be physically hosted (and linked to) in our site. What happens if those videos go viral and our bandwidth cost explodes? The video is password protected. The solution I've thought of for this is: Upload the user's video to our (password-protected site) and to Youtube at the same time, as an unlisted video. The user can access our site with his password and download his video (to watch on his TV or whatever). If the users hits the "share" button, we show him the Youtube link... and we turn the video into a listed one. This seems in line with the ideas in Using YouTube as a CDN, and there didn't seem to be any objections in that question. I'm posting this just to confirm that my idea doesn't violate any Youtube TOS, and also to see if it is a good one or there might be better alternatives.

• What technical details should a programmer of a web application consider before making the site public?

  - by Joel Coehoorn

  What things should a programmer implementing the technical details of a web application consider before making the site public? If Jeff Atwood can forget about HttpOnly cookies, sitemaps, and cross-site request forgeries all in the same site, what important thing could I be forgetting as well? I'm thinking about this from a web developer's perspective, such that someone else is creating the actual design and content for the site. So while usability and content may be more important than the platform, you the programmer have little say in that. What you do need to worry about is that your implementation of the platform is stable, performs well, is secure, and meets any other business goals (like not cost too much, take too long to build, and rank as well with Google as the content supports). Think of this from the perspective of a developer who's done some work for intranet-type applications in a fairly trusted environment, and is about to have his first shot and putting out a potentially popular site for the entire big bad world wide web. Also, I'm looking for something more specific than just a vague "web standards" response. I mean, HTML, JavaScript, and CSS over HTTP are pretty much a given, especially when I've already specified that you're a professional web developer. So going beyond that, Which standards? In what circumstances, and why? Provide a link to the standard's specification.

• Will an online degree get you a job that requires "CS or equivalent 4-year degree"? [on hold]

  - by qel

  I'm a nerdy slacker type who didn't get my life together till I was 30. I've had a real job for a couple years doing C#/SQL. I've gotten several raises, but I'm making less than most developers, and the atmosphere is ... not positive. Looking for a new job, I think my applications get thrown out because I don't have a degree. And I want to finish a Bachelor's just to feel like less of a loser. I have a lot of college credits from 1996-2003 and a low GPA, so I don't know if that's worth much. An online degree looks like a good option, but I just don't know what I should be looking at for online schools because they all look like fake degrees. If they had programs equivalent to a real Comp Sci degree, I don't think they would have weird sounding names like they do. University of Phoenix has a B.S./Information Technology-Software Engineering. DeVry has a B.S./Computer Engineering Technology program. But that's not CS, and most other things I see have even more fake-sounding names. Are these useless degrees? Some people say DeVry and UoP are acceptable, some people say they're a joke. I have enough experience now, though, that maybe all I'm missing is being able to check the box that I have a 4-year degree. Harvard Extension seems like a real degree, even if it isn't a real Harvard degree, but I'd have to live there at least 3 months, which kinda defeats the purpose of an online degree fitting around work.

• Architecture : am I doing things right?

  - by Jeremy D

  I'm trying to use a '~classic' layered arch using .NET and Entity Framework. We are starting from a legacy database which is a little bit crappy: Inconsistent naming Unneeded views (view referencing other views, select * views etc...) Aggregated columns Potatoes and Carrots in the same table etc... So I ended with fully isolating my database structure from my domain model. To do so EF entities are hidden from presentation layer. The goal is to permit an easier database refactoring while lowering the impact of it on applications. I'm now facing a lot of challenges and I'm starting to ask myself if I'm doing things right. My Domain Model is highly volatile, it keeps evolving with apps as new fields needs are arising. Complexity of it keeps raising and class it contains start to get a lot of properties. Creating include strategy and reprojecting to EF is very tricky (my domain objects don't have any kind of lazy/eager loading relationship properties): DomainInclude<Domain.Model.Bar>.Include("Customers").Include("Customers.Friends") // To... IFooContext.Bars.Include(...).Include(...).Where(...) Some framework are raping the isolation levels (Devexpress Grids which needs either XPO or IQueryable for filtering and paging large data sets) I'm starting to ask myself if : the isolation of EF auto-generated entities is an unneeded cost. I should allow frameworks to hit IQueryable? Slow slope to hell? (it's really hard to isolate DevExpress framework, any successful experience?) the high volatility of my domain model is normal? Did you have similar difficulties? Any advice based on experience?

• Disaster Recovery Example

  Previously, I use to work for a small internet company that sells dental plans online. Our primary focus concerning disaster prevention and recovery is on our corporate website and private intranet site. We had a multiphase disaster recovery plan that includes data redundancy, load balancing, and off-site monitoring. Data redundancy is a key aspect of our disaster recovery plan. The first phase of this is to replicate our data to multiple database servers and schedule daily backups of the databases that are stored off site. The next phase is the file replication of data amongst our web servers that are also backed up daily by our collocation. In addition to the files located on the server, files are also stored locally on development machines, and again backed up using version control software. Load balancing is another key aspect of our disaster recovery plan. Load balancing offers many benefits for our system, better performance, load distribution and increased availability. With our servers behind a load balancer our system has the ability to accept multiple requests simultaneously because the load is split between multiple servers. Plus if one server is slow or experiencing a failure the traffic is diverted amongst the other servers connected to the load balancer allowing the server to get back online. The final key to our disaster recovery plan is off-site monitoring that notifies all IT staff of any outages or errors on the main website encountered by the monitor. Messages are sent by email, voicemail, and SMS. According to Disasterrecovery.org, disaster recovery planning is the way companies successfully manage crises with minimal cost and effort and maximum speed compared to others that are forced to make decision out of desperation when disasters occur. In addition Sun Guard stated in 2009 that the first step in disaster recovery planning is to analyze company risks and factor in fixed costs for things like hardware, software, staffing and utilities, as well as indirect costs, such as floor space, power protection, physical and information security, and management. Also availability requirements need to be determined per application and system as well as the strategies for recovery.

• PHP Image gallery that integrates well into custom CMS

  - by Thorarin

  I've been trying to find an image gallery that plays nice with our custom CMS. I've evaluated a number of them, but none of them seems to have the feature list that I would like: Run on LAMP environment Free software or low license costs (the website belongs to a non-profit organisation) Multi-user support Multiple albums. We're posting concert pictures, and would like an album per event. Pluggable authentication system. I want to reuse the accounts we have for our CMS. Permissions can be done inside the gallery itself, but I want to have a single sign on solution in a maintainable manner, by writing my own plugin/add-on for the software. Upload support (multiple images at the same time) And preferrably also: Can be integrated into a PHP page layout without IFRAMEs Automatic resizing of uploaded images to a maximum size Ability for visitors to place comments This combination is proving hard to find, especially the authentication requirement. I don't want to mess around all over the place in the source code to make it use the existing authentication. A plugin would be ideal, but alternatively a well thought out software design that allows for maintainable surgical changes would be acceptable. Any suggestions on which software I should take a closer look into?

• Model a chain with different elements in Unity 3D

  - by Alex

  I have to model, in unity 3D, a chain that is composed of various elements. some flexible, some rigid. The idea is to realize a human-chain where each person is linked to the other by their hands. I've not tried to implement it yet as i've no idea on what could be a good way to do it. In the game i've to manage a lot of chains of people... maybe also 100 chains composed of 11-15 people. The chain will be pretty simple and there won't be much interaction... Probabily some animation of the people one at time for each chain and some physic reaction (for example pushing a people in a chain should slightle flex the chain) the very problem of this work is that in the chain each object is composed by flexible parts (arms) and rigid parts (the body) and that the connection should remain firm... just like when people handshake... hands are firm and are the wrists to move. i can use C4D to model the meshes. i know this number may cause performance problems, but it's also true i will use low-poly versions of human. (for the real it won't be human, but very simple toonish characters that have harms and legs). So actually i'm trying to find a way to manage this in a way it can work, the performance will be a later problem that i can solve. If there is not a fast 'best-practiced' solution and you have any link/guide/doc that could help me in finding a way to realize this is, it would be very appreciated anyway if you post it. thanks

• Software development company business plan

  - by Navi

  I apologize in advance if this is the wrong forum for this question, so please forward me to the right place. I have about 10 years professional experience as software developer. Mostly on the Java platform doing server side programs. I have picked up a bit of Linux skills on the way as well. I know HTML and Javascript, so I can make a website that would not be too ugly, but I am not going to win any prizes with it. In fact I think I am pretty terrible in the user interface department. My initial plan is to do Android development. I read a few Android books and tried making a few apps. Since it is Java based I think I got the technical side down. Lately I have been thinking about iphone and Mac development, because of the relevant app store/development programs. The trouble is I don't know Objective C. As a side question, how long would it take me to become proficient in Objective C? Considering that I am working on my own and could hire somebody to help me for a short time for low wages if necessary what are my options? What are the pro and cons of the development programs app stores of Android and Apple? Which development/app stores are out there beside the ones I mentioned? Do you think it is necessary to find funds to get me started or should I just use my savings? If you have positive/negative experiences in a similar situations can you please share them? Thanks for your help.

• Not All iPhone 5 and Galaxy SIII in Some Markets #UX #mobile #BBC #L10n

  - by ultan o'broin

  The BBC World Service provides news content to more people across the globe, and has launched a series of new apps tailored for Nokia devices, allowing mobile owners to receive news updates in 11 different languages. So, not everyone using an iPhone 5 or Samsung Galaxy SIII then? hardly surprising given one of these devices could cost you a large chunk of your annual income in some countries! The story is a reminder of taking into account local market requirements and using a toolkit to develop solutions for them. The article tells us The BBC World Service apps will feature content from the following BBC websites: BBC Arabic, BBC Brasil (in Portuguese), BBC Chinese, BBC Hindi, BBC Indonesia, BBC Mundo (in Spanish), BBC Russian, BBC Turkce, BBC Ukrainian, BBC Urdu and BBC Vietnamese. Users of the Chinese, Indonesian and Arabic apps will receive news content but will also be able to listen to radio bulletins.It’s a big move for the BBC, particularly as Nokia has sold more than 675 million Series 40 handsets to date. While the company’s smartphone sales dwindle, its feature phone business has continued to prop up its balance sheet. Ah, feature phones. Remember them? You should! Don't forget that Oracle Application Development Framework solution for feature phones too: Mobile Browser. So, don't ignore a huge market segment and opportunity to grow your business by disregarding feature phones when Oracle makes it easy  for you to develop mobile solutions for a full range of devices and users! Let's remind ourselves of the different mobile toolkit solutions offered by Oracle or coming soon that makes meeting the users of global content possible. Mobile Development with ADF Mobile (Oracle makes no contractual claims about development, release, and timing of future products.) All that said, check out where the next big markets for mobile apps is coming from in my post on Blogos: Where Will The Next 10 Million Apps Come From? BRIC to MIST.

• My game seems to be incompatible with recording software. What could be causing this?

  - by Lewis Wakeford

  I've just finished a little Game-Dev project for university and I need to record a video to accompany my submission (just in case they can't get my source to work). Basically my game doesn't work at all when FRAPS or Bandicam attempts to attach to it, I get a black screen and a stream of GL INVALID OPERATION messages from my error reporting code. Dxtory can't seem to hook into it correctly at all, it doesn't display it's FPS counter or anything. My game logic appears to be running correctly from the debug traces, it just seems like all the gl library calls break. I don't know a huge amount about how these programs operate so I don't really know what I could be doing to cause this. I've heard they read from the OpenGL frame buffers so maybe I'm doing something wrong there? I'm letting GLFW and GLEW do all the low level initialization, but I have successfully recorded projects with the same setup and recording software. Essentially, has anyone ever run into something like this before or do you know anything about how these programs work that could give a clue as to the cause of the issue?

• UFW blocking random packets on 443

  - by s2jcpete

  All, I have UFW setup to allow traffic on port 443. It works as expected, though I have a large amount of UFW Block log entries. To Action From -- ------ ---- 80 ALLOW Anywhere 443 ALLOW Anywhere 22222 ALLOW Anywhere 80 ALLOW Anywhere (v6) 443 ALLOW Anywhere (v6) 22222 ALLOW Anywhere (v6) However in my syslog file I see this: [UFW BLOCK] IN=eth0 OUT= MAC=XXX SRC=<foreignip> DST=<serverip> LEN=40 TOS=0x00 PREC=0x00 TTL=116 ID=22025 DF PROTO=TCP SPT=49622 DPT=443 WINDOW=0 RES=0x00 ACK RST URGP=0 About 30 or so seconds later pound (which I'm using for SSL decryption and port redirection) throws a connection timed out messsage. I'm assuming this is because UFW is blocking the packet. I'm at a loss as to an explination. Could the packet be malformed or something, is this normal? Edit - I have since changed the /etc/defaults/ufw and set ipv6=no, so the v6 rules are no longer in the mix. The server is still showing the block / connection timed out behavior though. The new ufw status output is: Status: active Logging: on (low) Default: deny (incoming), allow (outgoing) New profiles: skip To Action From -- ------ ---- 80 ALLOW IN Anywhere 443 ALLOW IN Anywhere 22222 ALLOW IN Anywhere
