  • Two different subwoofers aren't working on my machine or my phone

    - by Philluminati
    I have speakers that come with my computer. Two small desktop speakers and a subwoofer with a base volume control on the back. It's worked for years. I was listening to Spotify on my speakers as loud they would possibly go and with the base turned up to max and suddenly the subwoofer stopped working. I've plugged the speakers into my Android HTC Desire Z handset and again, the desktop speakers play music but the subwoofer doesn't (even after fiddling with the volume control). So I figured I'd broken it. I went to Amazon and bought a replacement one. I bought this one: http://www.amazon.co.uk/dp/B002N46YD8/ref=pe_217191_31005151_dp_1 but it doesn't work either, on either my desktop nor my Android phone. I had a play with alsamixer and the LFE and center controls are switched on and the speakers are okay... but still no base. Am I unlucky enough to bought a new subwoofer which is already broken out of the box or is there something else which is wrong and I could look into please? Are there any other tests which I could perform to see if the problem is me or not?

  • Small store infrastructure - where to begin?

    - by KevinM1
    It looks like my older brother is about to change jobs - from lawyer to shooting range proprietor - and since I'm the family 'computer guy' I have the task of coming up with and setting up the in-store equipment. Only problem, I don't know how to start or where to look. I'm a web programmer, not an IT specialist. To that end, I figured I should ask the pros. Users: 3 (myself, my brother, and his business partner) Equipment: 1 Windows (likely 7) desktop for POS software, 1 Windows desktop/laptop for backroom use (bookkeeping, etc.) Other: ?? I'm looking for a reliable and, well, idiot-proof way to handle backups. Neither my brother nor his business partner are tech savvy (A web browser, email, MS Word and Excel are about the extent of their knowledge), so I need something they can handle. On-site would be preferable to off-site, given my brother's hesitance to have sensitive business data be handled by an outside source. I'm also looking for a small on-site server. I estimate that, at most, only 2-3 users will need access. A linux solution would keep costs down, but I'm concerned about Windows <- linux interoperability. Would the store security cameras' storage be handled by the security company, or would we have to stream that data to our own server? I know from my own experience with personal security that the company gives/loans a recording device to the home owner, but I'm not sure about business security. I know this sounds like a shopping list, and it's pretty vague. I wish I could give more detail, but between my own ignorance and things not being 100% nailed down on the business end, I'm a bit stuck. At the very least I'd like a nudge - links on a place to start, what to look for, things I need to think about, etc. - for this endeavor. Thanks.

  • Vista Screen resolution Changes when Switching Users

    - by Benjol
    I regularly have a problem when switching between users in Vista - the screen resolution drops down to 800x600. If I try to set the resolution back to the maximum, it says nothing, but just keeps it at 800x600. I can set it back to an intermediate value. Otherwise I have to either restart the PC, or sometimes if I log off one of the users, I can then set the resolution back to max. Might it also have something to do with using sleep mode instead of performing regular shutdowns? I thought it might be related to the desktop background image taking up too much space, but even with plain colours, the problem still occurs. There is an enormous thread on this here, but not really any answers. From what I can gather from that thread, it isn't related to any particular applications, nor limited to a particular make of graphics card or monitor, so I don't think that including hardware details is useful. This is a very annoying problem, as it screws up my desktop and screen layout every single time. Has anyone here experienced this problem or found a solution? I've noticed that Windows Update has tried to install nVidia updates and apparently they've failed on several occasions. Not sure if that is of any relevance or not. UPDATE The last post on the thread: FWIW - I had this problem for about 2 years and wrote a number of posts in this thread in the past. It survived OS reinstallation, change of practically all of my hardware piece by piece (mobo, cpu, monitor, graphics card, memory, power supply...) I used to be affected by this annoying problem at least once every 24-48 hours. About 1.5 months ago I wiped out my 32 bit vista ultimate installation and installed Windows7 ultimate 64 bit from scratch and never saw this problem again. GOOD RIDDANCE. Vista was a pathetic piece of __ that felt like a flashback to the old [horrible] NT4/Windows95 days. I was seriously considering switching over to Apple/Mac OSX if this problem persisted.

  • Diagnosing "The specified module could not be found" on IIS7 with ASP.Net

    - by Baldy
    I am migrating some web apps from a windows 2003 server with IIS6 server to a Windows server 2008 R2 server with IIS7. One of the apps, which runs on asp.net v2.0 using forms authentication will not load. It gives me the following error... The specified module could not be found. (Exception from HRESULT: 0x8007007E) Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: System.IO.FileNotFoundException: The specified module could not be found. (Exception from HRESULT: 0x8007007E) Now i fully understand that the app cannot load some kind of resource due to a FileNotFoundException, but i am struggling to diagnose exactly where in the application this is happening, as it does not tell me what the module is, nor what file it is looking for. I have enabled failed request tracing and i get back a complete request trace, yet i cannot find anything that gives me detail on this specific error, or the module involved. Any advice on diagnosing the root cause of the issue would be greatly appreciated.

  • postfix not sending domain mail to mx

    - by orlandoresorts
    I'm trying to get postfix to forward email to my domain which is hosted by gmail. As I don't have any users on my server nor do I want to. Here's how I have things set up.. LEt's say you and I have a domain called mcdonalds.com the registrar has mcdonalds.com MX records pointing to gmail. (everything works for like a year) Now we set up a server to host a website. Then we create a mail account called [email protected] and send mail locally from the server using roundcube. This works. We can send mail to cnn.com we can send mail to serverfault.com we can email any/everyone. BUT we cannot send mail to our own domain mcdonalds.com So I cannot email [email protected] I cannot email [email protected] I cannot email [email protected] It gives the error: SMTP Error (450): Failed to add recipient "[email protected]" (4.1.1 : Recipient address rejected: User unknown in virtual mailbox table). I'm guessing because it is looking at the local server to find the mailbox and it doesn't exist. So how to I tell the server for any mail going to mcdonalds.com for [email protected] to send to my external mail server and NOT to lookup on the local www box we set up with zpanel. Any ideas?

  • HP Proliant DL380 G4 - Can this server still perform in 2011?

    - by BSchriver
    Can the HP Proliant DL380 G4 series server still perform at high a quality in the 2011 IT world? This may sound like a weird question but we are a very small company whose primary business is NOT IT related. So my IT dollars have to stretch a long way. I am in need of a good web and database server. The load and demand for a while will be fairly low so I am not looking nor do I have the money to buy a brand new HP Dl380 G7 series box for $6K. While searching around today I found a company in ATL that buys servers off business leases and then stripes them down to parts. They clean, check and test each part and then custom "rebuild" the server based on whatever specs you request. The interesting thing is they also provide a 3-year warranty on all their servers they sell. I am contemplating buying two of the following: HP Proliant DL380 G4 Dual (2) Intel Xeon 3.6 GHz 800Mhz 1MB Cache processors 8GB PC3200R ECC Memory 6 x 73GB U320 15K rpm SCSI drives Smart Array 6i Card Dual Power Supplies Plus the usual cdrom, dual nic, etc... All this for $750 each or $1500 for two pretty nicely equipped servers. The price then jumps up on the next model up which is the G5 series. It goes from $750 to like $2000 for a comparable server. I just do not have $4000 to buy two servers right now. So back to my original question, if I load Windows 2008 R2 Server and IIS 7 on one of the machines and Windows 2008 R2 server and MS SQL 2008 R2 Server on another machine, what kind of performance might I expect to see from these machines? The facts is this series is now 3 versions behind the G7's and this series of server was built when Windows 200 Server was the dominant OS and Windows 2003 Server was just coming out. If you are running Windows 2008 R2 Server on a G4 with similar or less specs I would love to hear what your performance is like.

  • Dell Latitude D510 Runs From Battery But Not AC Adapter

    - by Jason George
    I have a Dell Latitude D510 that went belly up around two years ago. It will run from the battery, however, the wall adapter will neither power the machine nor charge the battery. Once the battery is dead, the machine is dead. Since it died I've searched repeatedly for solutions. I've tried a new AC adapter and even removed and replaced the DC jack thinking one of the solder joints might be bad. Both to no avail. After two years of searching I finally found the answer today. Since it's such a simple fix and I had such a hard time finding it I wanted to post the info for others (as it is apparently a common issue with the D510). -----SOLUTION----- It seems this is commonly caused by a cracked solder joint at pin 1 on an inductor filter pair (FL2) near the power jack. Pins 1 and 4 are ground and pins 2 and 3 are power. There should be 20V from 1 to 2 and 3. Anything less indicates a cracked joint that is increasing resistance and dropping the supply voltage. Repair simply requires reflowing all four pins with a little added solder for security. Detailed instructions can be found here. Dell Latitude D510 solder problem

  • IE6 does not follow 302 redirect - displays 404 instead

    - by Dexter
    One of our clients has reported that they are experiencing 404 (file not found) errors when attempting to navigate a website that we support. The behaviour only appears to affect her - other users on the same machine can navigate the website fine, but the problem follows her from one PC to another. I've had a good look through the IIS server logs and have identified the requests in question. The normal request pattern is as follows: POST /page.aspx - 80 - ... 401 1 0 POST /page.aspx - 80 DOMAIN/user ... 302 0 0 GET /anotherPage.aspx Request=833f80a5-f34c-4b0e-addb-d73e1ee1663a 80 - ... 401 1 0 GET /anotherPage.aspx Request=833f80a5-f34c-4b0e-addb-d73e1ee1663a 80 DOMAIN/user ... 200 0 However, requests for the affected user do not include a request for the redirected page, nor an entry for the 404, i.e.: POST /page.aspx - 80 - ... 401 1 0 POST /page.aspx - 80 DOMAIN/user ... 302 0 0 ... other unrelated requests Can anyone suggest what might trigger this behaviour, and how I might investigate the cause or prevent it from occuring? I read here that the Allow META refresh option in IE6 might trigger this behaviour, but I have not been able to replicate the behaviour by modifying this setting only.

  • Is this normal or does my AVG anitivirus have a virus? [closed]

    - by user390480
    Possible Duplicate: Computer is infected by a virus or a malware, what do I do now? [Note: This is not a duplicate and should not be closed as a duplicate as this is nothing like the other question. I am not asking if I have a virus, nor am I asking "what do I do now". I know that I have a virus and I know what to do. However, I am asking if these are normal AVG ads or if it has been taken over.] My Windows XP PC started acting strange and I am right now actually in Linux running off of a USB drive. I am running Avast under Linux and it has discovered some viruses on my XP drive. Some of the strange things happening in XP were: I could not get to Google.com My Hosts file was set to hidden and read only My Hosts file had an entry of ::1 And AVG had ads in it I've never seen before. Maybe it is normal but I Binged for AVG anti-virus and become.com but found no information. (The red lines and question mark are by me) Any thoughts?

  • Touchpad does not respond when I am holding key on the keyboard

    - by Tadeck
    I am experiencing strange problem with using my touchpad and keyboard simultaneously under Windows 7. I have HP tx2550ew (convertible tablet), and when I hold some key under Windows 7 (eg. space, a, s etc.), the touchpad seems to be blocking. I spotted this while playing Counter Strike. I am not playing much games, and I haven't been playing CS since January, so I am not sure when it started behaving like that. I have tested it also outside the game - when I hold space (eg. when on some web page and entering text into input field) or some letter key, the cursor is not able to move. The problem seems to not be occuring when I hold Shift, Ctrl nor Alt. Did any of you experience similar problem? Do you know what may have caused this? Is there any way I could check what is wrong with my laptop? I have been looking for a solution, but it seems I haven't been looking in right places. This is why I ask question here. Ps. I am unable to test whether this is touchpad-specific, because I have no mouse at my disposal at the moment (got used to touchpad so much I even find it more efficient and haven't been using a mouse with my laptop for months).

  • Excel data representation: show me all people who did not pass the exam

    - by dreftymac
    Background I have an excel spreadsheet with the results of a pass/no-pass exam. Students are allowed to take the exam as often as they want until they either pass, or give up trying. student ;; result ;; date [email protected] ;; no-pass ;; 2000-06-07 [email protected] ;; pass ;; 2000-06-07 [email protected] ;; pass ;; 2000-06-07 [email protected] ;; no-pass ;; 2000-06-07 [email protected] ;; pass ;; 2000-06-07 [email protected] ;; pass ;; 2000-06-08 [email protected] ;; no-pass ;; 2000-06-08 Question Using a pivot-table or something else, how can I get excel to show me a clean report or representation of this data on another sheet that answers the question: Who are all the people who took the exam, but never got a passing grade? In the above example it would just show me [email protected] ;; no-pass ;; with all the dates that delta took the exam. I know excel is not a database nor a reporting tool per-se, but it would be great if I could get it to do this.

  • Delete cell content in Libre (Open) Office based on the cell value

    - by take2
    I have a huge csv file (tens of thousands of rows) that I need to filter based on different criteria. After trying to find a proper CSV editor, I decided to use LibreOffice Calc. CSVed is great, but it doesn't support neither UTF-8 nor macros for advanced filtering. So, there are 4 columns, 3 of which contain numbers (with decimal numbers) and 1 of which contains text. I'm trying to find a way to delete rows with a macro code. I can achieve the desired behavior with filters too, but it's annoying to type all of the filtering values over and over again and there doesn't seem to be a way to export the filter and us it repeatedly. These rows should be deleted: The ones that don't contain certain words in textual column (column A). There are a few thousand different words used in that column and I want to keep only the rows that contain one of about 30 words in that column. Additionally, the number is the other columns should be bigger than 3.8 (column B), 4.5 (column C) and smaller than 20 (column C). The row-deletion type is "Shift up". Hopefully I have explained it well. Thanks a lot in advance for your help!

  • Switch to IPv6 and get rid of NAT? Are you kidding?

    - by Ernie
    So our ISP has set up IPv6 recently, and I've been studying what the transition should entail before jumping into the fray. I've noticed three very important issues: Our office NAT router (an old Linksys BEFSR41) does not support IPv6. Nor does any newer router, AFAICT. The book I'm reading about IPv6 tells me that it makes NAT "unnecessary" anyway. If we're supposed to just get rid of this router and plug everything directly to the Internet, I start to panic. There's no way in hell I'll put our billing database (With lots of credit card information!) on the internet for everyone to see. Even if I were to propose setting up Windows' firewall on it to allow only 6 addresses to have any access to it at all, I still break out in a cold sweat. I don't trust Windows, Windows' firewall, or the network at large enough to even be remotely comfortable with that. There's a few old hardware devices (ie, printers) that have absolutely no IPv6 capability at all. And likely a laundry list of security issues that date back to around 1998. And likely no way to actually patch them in any way. And no funding for new printers. I hear that IPv6 and IPSEC are supposed to make all this secure somehow, but without physically separated networks that make these devices invisible to the Internet, I really can't see how. I can likewise really see how any defences I create will be overrun in short order. I've been running servers on the Internet for years now and I'm quite familiar with the sort of things necessary to secure those, but putting something Private on the network like our billing database has always been completely out of the question. What should I be replacing NAT with, if we don't have physically separate networks?

  • How far should we take the N+N redundancy craziness ?

    - by Brann
    The industry standard when it comes from redundancy is quite high, to say the least. To illustrate my point, here is my current setup (I'm running a financial service). Each server has a RAID array in case something goes wrong on one hard drive .... and in case something goes wrong on the server, it's mirrored by another spare identical server ... and both server cannot go down at the same time, because I've got redundant power, and redundant network connectivity, etc ... and my hosting center itself has dual electricity connections to two different energy providers, and redundant network connectivity, and redundant toilets in case the two security guards (sorry, four) needs to use it at the same time ... and in case something goes wrong anyway (a nuclear nuke? can't think of anything else), I've got another identical hosting facility in another country with the exact same setup. Cost of reputational damage if down = very high Probability of a hardware failure with my setup : <<1% Probability of a hardware failure with a less paranoiac setup : <<1% ASWELL Probability of a software failure in our application code : 1% (if your software is never down because of bugs, then I suggest you doublecheck your reporting/monitoring system is not down. Even SQLServer - which is arguably developed and tested by clever people with a strong methodology - is sometimes down) In other words, I feel like I could host a cheap laptop in my mother's flat, and the human/software problems would still be my higher risk. Of course, there are other things to take into consideration such as : scalability data security the clients expectations that you meet the industry standard But still, hosting two servers in two different data centers (without extra spare servers, nor doubled network equipment apart from the one provided by my hosting facility) would provide me with the scalability and the physical security I need. I feel like we're reaching a point where redundancy is just a communcation tool. Honestly, what's the difference between a 99.999% uptime and a 99.9999% uptime when you know you'll be down 1% of the time because of software bugs ? How far do you push your redundancy crazyness ?

  • Ubuntu xrandr rotate issue

    - by user83544
    I've just bought a second monitor for my PC which happens to be a pivot monitor. I've already read lots of forums related to my problem but haven't come across a solution - I have the same symptoms as dozens of posts but no matter whatever I try it just doesn't work. I've already changed the xorg.conf file and added in the device section just under Driver "nvidia" the following for my second monitor: Option "RandRRotation" "on" When I save and reboot I try to rotate my screen with the nvidia X server settings by choosing the second monitor and clicking either "left" or "right" for the rotation. It immediately exits the nvidia settings window and does nothing. I tried within the terminal by typing: xrandr -o right I get the following error: X Error of failed request: BadMatch (invalid parameter attributes) Major opcode of failed request: 154 (RANDR) Minor opcode of failed request: 2 (RRSetScreenConfig) Serial number of failed request: 14 Current serial number in output stream: 14 I actually manage to rotate it with Option "Rotate" "CCW" instead of "RandRRotation". The problem with this solution is that you get the second monitor in the right position, but any window you open on that screen is practically unchangeable. You can't change the size nor move it, making it useless for reading PDFs, which is the main reason why I bought this second screen to help me write my thesis. Any help is really appreciated. sudo lshw -c video hiram@hiram-linux:~$ sudo lshw -c video *-display description: VGA compatible controller product: nVidia Corporation vendor: nVidia Corporation physical id: 0 bus info: pci@0000:01:00.0 version: a1 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress vga_controller bus_master cap_list rom configuration: driver=nvidia latency=0 resources: irq:16 memory:f8000000-f9ffffff memory:d8000000-dfffffff memory:d4000000-d7ffffff ioport:dc00(size=12 memory:fbd80000-fbdfffff

  • This web site needs a different Google Maps API key. A new key can be generated at http://code.googl

    - by MJI
    Apologies in advance if this is the wrong place to post. I tried searching for this issue and all that seemed to come up were questions posted from people who had this issue with their web pages. I couldn't find questions related to this issue from a laypersons perspective. I'm not a developer. I have no domain, nor wish to have one at the time. Rather I'm just a regular person who likes to upload photos to some photo related sites. My uploading process constantly gets interrupted by one of these annoying API errors. I get it at least two times, one when I click the page to upload, and also right after it has uploaded. It also pops up if I go to edit a photo or delete it. This interrupts my browsing experience until I click okay. I just want a fix for the annoying without having to register for a key. I tried before and it required a web domain. I rather not have to create a domain and go through such hoops just to fix this. Is there a solution for this problem that doesn't require registration? Another thing to note: I have used two computers. One has the message pop-up and the other doesn't. What is different about the two computers?

  • Recommended offline on-demand virus scanners

    - by ashh
    I have never run full anti-virus on my Windows XP systems. Instead I use various anti-malware tools to manually perform scans every few weeks. This approach, combined with Windows updates and general care about what web-sites I visit and what files I download has kept me 99% free of problems. The remaining 1% has occurred when I download files that I know may contain malware, but still decide the risk is worth it. When on 2 occasions in 10 years I did get caught doing this, I realised that being able to easily scan them would most likely have avoided getting infected. I don't need, or want, to run a "stay resident" anti-virus. Also, the online scanners such as Kaspersky etc limit uploads to small files, so these are not always useful. In summary I would like to simply be able to download a file and then manually initiate an on demand anti-virus scan, on the downloaded file only. I'm sure some/most Anti-Virus do both, however once again I don't really want to pay for or need the stay resident part. Any recommendations (commercial or free)? UPDATE: This is not an exact duplicate, nor a possible duplicate. I searched for and read other questions on anti-virus here at SuperUser and found none that answered my question. I am specifically asking about anti-virus scanners that run ON-DEMAND locally on the computer, not online scanners.

  • What is going on when I can't access an SMB server share (not accessible error) until I run cmdkey to delete the credential?

    - by Warren P
    I have a network connection share issue. The first connection works, and seems to stay connected for at least a few hours. However, after each time my windows 7 PC reboots, it can no longer form a network connection to the shared folder, nor browse to it, until I not only unmap and remap the mapped drive, but also, I have to use cmdkey to delete the stored credentials like this: cmdkey /delete:Domain:target=HOSTNAME My work PC is on a domain, and I am not the IT administrator, but I'm curious if there is anything I can do to investigate this issue. Any settings in registry or group policy that I could examine to see why the first connection works, but each subsequent attempt (once a stored credential exists) to browse or use the connection, fails with a connection error saying it is "not accessible", like this: I do not even get any error until at least several minutes go by. THe first thing I see is a window frozen and empty, and then I get this error: This has happened when connecting to a share on a DROBO device, and on a share which is not on the domain, but which was a Microsoft Home Server. I wonder if there's something broken in WIndows 7 professional with regards to connecting to non-domain shares when an active directory domain controller exists, and a particular workstation is joined to a domain? The problem only occurs if I click "remember credentials". It is not fixed by any amount of working with net use. Usingcmdkey to delete all stored credentials for the host is the only way to get back in, and it affects all non-domain shared folders. Update I'm hoping there are some registry locations I could check that could be misconfigured in some way that might explain why SMB/CIFS stored credentials for non-domain systems seem to be auto-invalidated in this weird way. Knowing how whacko Microsoft Windows domain and security handling is sometimes, this could be some kind of stupid "feature".

  • How to kill ostensibly immortal process?

    - by DeeDee
    I had some huge file transfers operating on an NFS mount. The server on which the mount point resided was carelessly rebooted, and now the server from which these large transfers were initiated seems to be bogged down by them. If I run top, I see the following: The first thing I tried was to run kill with each the -1 -2 -9 and -15 flags, and each of the process ids shown above in turn. This allowed me to proceed, but didn't kill the processes. The next thing I attempted was to reboot the server, but neither reboot nor shutdown -r now worked. When I ran shutdown -r now the standard broadcast message was sent out, but the sever did not reboot. I confirmed this by looking at the server uptime, which was 25 days. So now I'm a little stuck. I'm running these commands as root. EDIT: Here's another interesting tidbit: In top, I don't see that any other processes are using more than a fraction of a percent of memory or more than 5% of CPU. EDIT 2: output of /var/log/messages

  • Adding file to /etc/cron.d doesn't make it run (ubuntu 10.04)

    If I scp a cron file into /etc/cron.d it doesn't run unless I edit the file and change the command. Then crond seems to pick up the cron file.

  • KVM virtual machine unable to access internet

    - by peachykeen
    I have KVM set up to run a virtual machine (Windows Home Server 2011 acting as a build agent) on a dedicated server (CentOS 6.3). Recently, I ran updates on the host, and the virtual machine is now unable to connect to the internet. The virtual network is running through NAT, the host has an interface (eth0:0) set up with a static IP (virt-manager shows the network and its IP correctly), and all connections to that IP should be sent to the guest. The host and guest can ping one another, but the guest cannot ping anything above the host, nor can I ping the guest from anywhere else (I can ping the host). Results from the guest to another server under my control and from an external system to the guest both return "Destination port unreachable". Running tcpdump on the host and destination shows the host replying to the ping, but the destination never sees it (it doesn't even look like the host is bothering to send it on at all, which leads me to suspect iptables). The ping output matches that, listing replies from 192.168.100.1. The guest can resolve DNS, however, which I find rather odd. The guest's network settings (connection TCP/IPv4 properties) are set up with a static local IP (192.168.100.128), mask of 255.255.255.0, and gateway and DNS at 192.168.100.1. When originally setting up the vm/net, I had set up some iptables rules to enable bridging, but after my hosting company complained about the bridge, I set up a new virtual net using NAT and believe I removed all the rules. The VM's network was working perfectly fine for the last few months, until yesterday. I haven't heard anything from the hosting company, didn't change anything on the guest, so as far as I know, nothing else has changed (unfortunately the list of packages updated has since fallen off scrollback and I didn't note it down).

  • Can't access site internally, but DNS works

    - by BloodyIron
    1) I have apache2 running a vhost for a website. 2) This apache2 instance is already successfuly setup for other websites on it to be accessible internally and externally. 3) I am using an internal bind9 server to resolve the new website's domain internally to the private IP. This bind9 server is not public facing, nor is it the master server on the internet. 4) The DNS internally resolves to the right IP. 5) Firefox reports "server not found". 6) I have copied the config almost identically to other configs that are known to work (adjusting for proper paths of course). In turn I have reloaded and restarted apache2 repeatedly. 7) I have an entry to forward .org .info .net alternative TLDs to .com in the vhost config for this domain, and my browser goes from .org to .com despite note #5. 8) /var/log/apache2/access.log shows when someone externally tries to access the site, but no activity is observed when someone tries to access internally. Changing the log level does not appear to improve the situation. 9) I am out of ideas, nothing appears to be wrong. Please help? To be explicit. Why is this new site unreachable internally? I would like to clarify on something, even though I have already outlined this. YES I know this system is in a private network. NO it is not going through a router. YES I am using an internal DNS server (bind9) to resolve, and YES it does resolve to the proper internal IP. YES other websites on the same server setup in the same way with internal resolution work right now and have done for a while. Everything for this domain is setup the same as the other working domains as far as I can tell. The other working domains are internally AND externally accessible. This domain I am working with is only currently externally accessible. When I go to it internally firefox tells me "Server not found".

  • Strange IP address showing up with OS X ssh

    - by user50799
    I was futzing around with DTrace on Mac OS X and found the following script that prints out information about connections being established: $ cat script.d syscall::connect:entry { printf("execname: %s\n", execname); printf("pid: %d\n", pid); printf("sockfd: %d\n",arg0); socks = (struct sockaddr*)copyin(arg1, arg2); hport = (uint_t)socks->sa_data[0]; lport = (uint_t)socks->sa_data[1]; hport <<= 8; port = hport + lport; printf("Port number: %d\n", port); printf("IP address: %d.%d.%d.%d\n", socks->sa_data[2], socks->sa_data[3], socks->sa_data[4], socks->sa_data[5]); printf("======\n"); } I run it in one window: $ sudo dtrace -s ./script.d Then I ssh to another machine from another window. I get this output from my dtrace window: CPU ID FUNCTION:NAME 0 18696 connect:entry execname: ssh pid: 5446 sockfd: 3 Port number: 22 IP address: 192.168.0.207 ====== 0 18696 connect:entry execname: ssh pid: 5446 sockfd: 5 Port number: 12148 IP address: 109.112.47.108 ====== ^C The first IP address I can explain (192.168.0.207), that's the machine I'm connecting to. But what's with the 109.112.47.108 machine? It doesn't show up in tcpdump nor netstat -an Is there something with my dtrace code or my understanding of how the connect system call works?

  • HP tx2510us shuts down without warning, now won't boot, no BIOS codes, screen doesn't light

    - by Tim S
    Hey all, HP tx2150us worked great for a year and a half, rarely it would shut down instead of sleeping. It started running hot sometimes, I installed Win7, worked great, still running hot. Before Xmas, it gave me evidence of video errors - jagged lines, rows missing. That same night, it started rebooting, then it shut off and wouldn't boot. It gave me a BIOS code, I shut it off to look up the code online. When I turned it on again, it won't boot at all. The LEDs all light up, the fan, HD, and optical all spin up, but the screen never lights up and it doesn't try to boot, nor does it blink any BIOS codes. It just acts like it's sleeping, and won't wake up. I suspected heat problems, so I disassembled it, cleaned the crap out of the fan, and reassembled it, breaking the stereo mic connector. Oh well. When I reassembled it, it booted up into Win7 again, but kept shutting down for no discernible reason. After a dozen or so random reboots like that, it is now back to where it was - turns on but doesn't boot or give BIOS codes. The screen never lights, and everything spins up then idles. Any ideas? I really can't afford to buy a new one and I use(d) it to take ALL my notes, that's why I got a tablet in the first place.

  • Attempting to emulate Apache MultiViews with Nginx try_files

    - by Samuel Bierwagen
    I want a request to http://example.com/foobar to return http://example.com/foobar.jpg. (Or .gif, .html, .whatever) This is trivial to do with Apache MultiViews, and it seems like it would be equally easy in Nginx. This question seems to imply that it'd be easy as try_files $uri $uri/ index.php; in the location block, but that doesn't work. try_files $uri $uri/ =404; doesn't work, nor does try_files $uri =404; or try_files $uri.* =404; Moving it between my location / { block and the regexp which matches images has no effect. Crucially, try_files $uri.jpg =404; does work, but only for .jpg files, and it throws a configuration error if I use more than one try_files rule in a location block! The current server { block: server { listen 80; server_name example.org www.example.org; access_log /var/log/nginx/vhosts.access.log; root /srv/www/vhosts/example; location / { root /srv/www/vhosts/example; } location ~* \.(?:ico|css|js|gif|jpe?g|es|png)$ { expires max; add_header Cache-Control public; try_files $uri =404; } } Nginx version is 1.1.14.
