• Apache + Bind Problems

  - by Gabriel

  Hello, I am using VirtualMin on Debian-50-lenny-64-LAMP (Debian Linux 5.0). I've upgraded some packages including "bind". Since the upgrade, both Apache and Bind stopped working. Here's the errors I get: Blockquote Starting web server: apache2apache2: Could not reliably determine the server's fully qualified domain name, using 78.46.92.11 for ServerName (98)Address already in use: make_sock: could not bind to address [::]:80 (98)Address already in use: make_sock: could not bind to address 0.0.0.0:80 no listening sockets available, shutting down Unable to open logs failed! and Failed to start BIND : Unknown error I am sure that some files were changed after the upgrade and this is a simple problems to solve, but unfortunately, it's the first time I am in this situation and I just couldn't find a solution. I've Googled about the errors but still couldn't make it work. Now I am sorry I did the update. I usually make updates to have the latest versions of the packages that are installed in the server. Any ideas?

• What's the difference between sudo su - postgres and sudo -u postgres?

  - by Craig Ringer

  PostgreSQL users peer authentication on unix sockets by default, where the unix user must be the same as the PostgreSQL user. So people frequently use su or sudo to become the postgres superuser. I often see people using constructs like: sudo su - postgres rather than sudo -u postgres -i and I'm wondering why. Similarly, I've seen: sudo su - postgres -c psql instead of sudo -u postgres psql Without the leading sudo the su versions would make some sense if you were on an old platform without sudo. But why on a less than prehisoric UNIX or Linux would you use sudo su ?

• Make a socket as a user but make it readable and writable by another

  - by user1598585

  I have a software that is run under user A, this software creates a socket in /sockets and the socket should be readable and writable by user B. I have tried setting the directory to have ownership A:A or A:B but when user A creates the socket, it ends up with uid A and gid A. Using ACLs has not helped so far, the default mask is preventing the rights to be effective. rw permisions for B will always turn into jusr r. If what I make is not a socket it will work fine. How can I best accomplish this task? (It is for a web-server where the web-application makes the socket and the web-server software forwards requests to it)

• Memory compatibility?

  - by nvillec

  I'm in the process of building a PC intended mostly for gaming and I've got a few questions. Currently, I only have the motherboard and CPU: Motherboard: GIGABYTE GA-Z68AP-D3 CPU: Intel Core i3-2120 My main question is about memory compatibility. I have 4 Hynix 2GB HMT125U7BFR8C-G7 with light-moderate use laying around and I'd love to save a few bucks if I can. I've read that this is server memory... a) Will that be a problem for PC use? b) Is it compatible with the motherboard? I've emailed Hynix and checked Crucial to no avail. If incompatible, what memory would be a good fit given the components I have? The motherboard has 4 sockets and supports up to 32GB, but I don't know that I have the budget for that at the moment. Thanks!!

• How do I fix Nginx config to work with multiple hosts of Unicorn?

  - by fred deAlmeida

  I have no problem instantiating multiple instances of unicorn on different unix sockets and ports. Works fine if I do url:port. My problem comes in correctly formatting nginx.conf to allow multipe upstream conditions. Whatever i do does not seem to work. One instance is fine works fine. Multiple gives me a ""upstream" directive is not allowed here error I am using the base nginx sample from the unicorn site. and doubling up the upstream area with differing terms. each is part of the http set. Any help would be amazing!

• Cat5 wiring in my home [closed]

  - by Mike

  I have problem with cat5 cabling First I ran a length of cable 30 metres to my bedroom 1 and and connected both ends to a wall sockets internally using my punch down tool, both ends look fine. I also ran a cable from bedroom 1 to bedroom 2 so my son can use same internet connection , i then parallel connected my cables in bedroom 1 against using punch down tool using same colours all the way through. I ran a Ethernet cable from modem to first wall socket close to it then at bedroom end used another Ethernet cable to connect pc, it wouldn't connect to pc so I disconnected bedroom 2 cable from bedroom 1 socket. I connected bedroom 1 to pc and it worked, but how do I connect bedroom 2 (obviously cat 5 cable bedroom 1 to 2 is in place) As soon as I connect one wire from bedroom2 I loose Internet connection!

• Why change net.inet.tcp.tcbhashsize in FreeBSD?

  - by sh-beta

  In virtually every FreeBSD network tuning document I can find: # /boot/loader.conf net.inet.tcp.tcbhashsize=4096 This is usually paired with some unhelpful statement like "TCP control-block hash table tuning" or "Set this to a reasonable value." man 4 tcp isn't much help either: tcbhashsize Size of the TCP control-block hash table (read-only). This may be tuned using the kernel option TCBHASHSIZE or by setting net.inet.tcp.tcbhashsize in the loader(8). The only document I can find that touches on this mysterious thing is the Protocol Control Block Lookup subsection beneath Transport Layer in Optimizing the FreeBSD IP and TCP Stack, but its description is more about potential bottlenecks in using it. It seems tied to matching new TCP segments to their listening sockets, but I'm not sure how. What exactly is the TCP Control Block used for? Why would you want to set its hash size to 4096 or any other particular number?

• Address already in use - Amazon AWS

  - by Peter

  I've run into a really weird issue. I was debugging a server 500 error script on our EC2 instance and found that we didn't have ioncube loaders installed. So I went to go install them and I created a new file at /etc/php.d/zend.ini and initially I inserted the value of extension=/usr/local/ioncube/ioncube_loader_lin_5.3.so and restarted httpd at which point it told me: The ionCube Loader is a Zend-Engine extension and not a module Please specify the Loader using 'zend_extension' in php.ini PHP Fatal error: Unable to start ionCube Loader module in Unknown on line 0 So I changed the contents of zend.ini to zend_extension=/usr/...etc. Now when I attempt to restart httpd I get this error: Starting httpd: (98)Address already in use: make_sock: could not bind to address [::]:80 (98)Address already in use: make_sock: could not bind to address 0.0.0.0:80 no listening sockets available, shutting down Unable to open logs I can't even run /etc/init.d/httpd stop without it erroring. I've since removed zend.ini to see if that's what caused it and it doesn't seem to be. Any ideas?

• Apache will not start after IP change

  - by Doron

  I'm running CentOS 5.8 and I had to change my server's IP address. Afterwards, I'm unable start Apache. I am also running virtualmin. The error I'm receiving is: Failed to start service Starting httpd: httpd: Could not reliably determine the server's fully qualified domain name, using 184.106.146.125 for ServerName (99) Cannot assign requested address: make_sock: could not bind to address 50.56.33.100:8080 no listening sockets available, shutting down Unable to open logs I edited my httpd.conf to point to the new IP address like such: #Listen 12.34.56.78:80 Listen 184.106.146.125:80 And looking at the error it still seems to be referring to the old ip address (50.*).

• Why does the CPU usage reach 100% when laptop is plugged in?

  - by Mayank

  I have an HP Elitebook 8440p with Windows 7 Ultimate, i7 Processor and 8 GB RAM. For the last couple of days, when I plug-in my laptop for charging, the CPU usage shoots up to 100% and remains there for around 15 minutes. No offending process shows up in Task Manager/Process Explorer but the laptop is practically unusable for that time. The CPU usage becomes normal when I remove the power cord but shoots up again when plugged back. This is happening with different power adapters/wall sockets so it might not be a faulty adapter issue. Why is this happening and any pointer to resolve this issue?

• Examples of applications where messages are guaranteed to turn up imediately

  - by James Hay

  I'm trying to find an example to show where data is sent from somewhere, whether manually or automatically, and is received IMMEDIATELY by the recipient, (doesn't matter whether we're talking mobile, desktop or whatever). An even better example would be where there were multiple recipients for the same message. It doesn't matter what the data is or the context it's used in, only the immediacy of receiving it. I was thinking that there might be some example in finance and the stock markets, but I haven't been able to find any through googling. IM clients are a great example of this and I think I'm basically looking for examples of applications that communicate over sockets. If anyone works on applications of this nature or knows of particular implementations, can you give me a quick run down of the use case and if it's commercial software the name of the software. This is all basically for research purposes so doesn't have to be particularly detailed. If anyone can help, thanks.

• Remove Windows 7's limitation on number of concurrent tcp connections (http web requests)

  - by Ghita

  I have an application that tries to open as many http requests as possible (in order to stress test a proxy implementation) It seems to me that Win7 (SP1) may have a limitation on number of concurrent opened connection (it may be the so called half-open state if I'm not wrong). Is there something I can do for client ? and also I test using a vista PC that acts as a proxy server. It would be great if I could configure it to sustain at least 50 new connections initiated / second on client side and many more on server. I made the modification according to this technet article by setting TcpNumConnections = 150 but it doesn't make a difference. I still only see about 20 tcp sockets associated with my http client by using tcpview.

• Do TCP/UDP connections add to the Windows incoming connection limit?

  - by user47899

  Hi all, I've tried to figure out what Microsoft means by "Windows sockets" and it all seems very vague. Basically we have customers that sometimes try to set up workgroups with close to 10 Windows XP computers with drive and printer shares and we're worried that some of the non-Windows Ethernet devices on the network will cause issues with the inbound connection limit outlined here where only 10 inbound connections can be active at one time. For example, there is an Ethernet Caller ID device that broadcasts UDP packets to all computers, and a kitchen display system that likewise broadcasts UDP. They may also have incoming TCP packets for our custom online ordering module. Do these TCP/UDP connections count toward the inbound connection limit? I'm aware that Windows 7 has increased the limit to 20 but we might have future customers that will push that limit. Thanks in advance

• wireless printer - entering WPA - is there a quicker way?

  - by camcam

  I have a wireless printer (Brother DCP-585CW). The wireless setup instruction says I should enter the WPA key to the printer. The key is entered using up and down buttons on the printer. So, I am supposed to enter 64 characters using up and down buttons. To enter 1 character, it takes on average (24+10)/2 = 17 times pressing the button (digits start after 24 letters). So 17*64 = 1088 times. Is there a quicker way to setup a wireless printer? Maybe there is a Windows program that discovers printers connected to computer through USB or Ethernet (my printer has both sockets) and allows to pre-configure it for wireless usage (enter the long WPA key)? Update There is BRAdmin program and it allows to set up almost all wireless settings... almost - all except WPA :(

• No SATA drives after PSU Upgrade

  - by hauptbenutzer

  I know this sounds a lot like this but I just confirmed that my MBR is fine as well as the SSD drive in question. What happened: I upgraded my be-quiet 700w PSU to the 1000w dark power pro. When I tried booting the system and none of the drives (all SATA) were detected, resulting in the "Boot device failure" error. After that I unplugged all but the boot drive, triple checked that all cables were in fact nice and tight inside their sockets, replaced both e-SATA and power cables ; still with the same outcome. Finally I reconnected my old PSU and sure enough the PC booted without any hassle (except of course for the direful construction that is currently occupying my desk). Does anybody have any advice on how to proceed? Surely, it is possible the PSU is faulty but are there other explanations? Thanks in advance PS. if of any help: Motherboard is GIGABYTE GA-PH67A-UD3-B3 H67 LGA 1155

• MaxConnections: is it a Client or Request count?

  - by ctacke

  IIS allows me to set a MaxConnections value in the configuration. What is unclear (to me anyway) is what that number means exactly, and I can't find a definitive documented answer. Is this the maximum number of clients that connect simultaneously, or is the maximum number of requests that can be running concurrently? For example, if I have a page that loads up some images, CSS files, scripts and content, each of those could reasonably be on a separate request socket with a modern browser. Is each of those sockets counted against the "max", or is it counted only as 1 since they are all requests from the same client address?

• How do I get through proxy server environments for non-standard services?

  - by Ripred

  I'm not real hip on exactly what role(s) today's proxy servers can play and I'm learning so go easy on me :-) I have a client/server system I have written using a homegrown protocol and need to enhance the client side to negotiate its way out of a proxy environment. I have an existing client and server system written in C and C++ for the speed and a small amount of MFC in the client to handle the user interface. I have written both the server and client side of the system on Windows (the people I work for are mainly web developers using Windows everything - not a choice) sticking to Berkeley Sockets as it were via wsock32 for efficiency. The clients connect to the server through a nonstandard port (even though using port 80 is an option to get out of some environments but the protocol that goes over it isn't HTTP). The TCP connection(s) stay open for the duration of the clients participation in real time conferences. Our customer base is expanding to all kinds of networked environments. I have been able to solve a lot of problems by adding the ability to connect securely over port 443 and using secure sockets which allows the protocol to pass through a lot environments since the internal packets can't be sniffed. But more and more of our customers are behind a proxy server environment and my direct connections don't make it through. My old school understanding of proxy servers is that they act as a proxy for external HTML content over HTTP, possibly locally caching popular material for faster local access, and also allowing their IT staff to blacklist certain destination sites. Customer are complaining that my software doesn't recognize and easily navigate its way through their proxy environments but I'm finding it difficult to decide what my "best fit" solution should be. My software doesn't tear down the connection after each client request, and on top of that packets can come from either side at any time, basically your typical custom client/server system for a specific niche. My first reaction is "why can't they just add my servers addresses to their white list" but if there is a programmatic way I can get through without requiring their IT staff to help it is politically better and arguably a better solution anyway. Plus maybe I'm still not understanding the role and purpose of what proxy servers and environments have grown to be these days. My first attempt at a solution was to use WinInet with its various proxy capabilities to establish a connection over port 80 to my non-standard protocol server (which knows enough to recognize and answer a simple HTTP-looking GET request and answer it with a simple HTTP response page to get around some environments that employ initial packet sniffing (DPI)). I retrieved the actual SOCKET handle behind WinInet's HINTERNET request object and had hoped to use that in place of my software's existing SOCKET connection and hopefully not need to change much more on the client side. It initially seemed to be my solution but on further inspection it seems that the OS gets first-chance at the received data on this socket since when I get notified of events via the standard select(...) statement on the socket and query the size of the data available via ioctlsocket the call succeeds but returns 0 bytes available, the reads don't work and it goes downhill from there. Can someone tell me of a client-side library (commercial is fine) will let me get past these proxy server environments with as little user and IT staff help as possible? From what I read it has grown past SOCKS and I figure someone has to have solved this problem before me. Thanks for reading my long-winded question, Ripred

• Android chess development design [on hold]

  - by Plejo

  I want to develop human vs human android chess game and I have bunch of new questions. I would like to have screen where online players are shown(nickname, rating) and when player challenge antoher player and he accpet it game begins. These are my questions: When player install application, does he have to create account/login or does every instance of installed application have some kind of ID so I can recognize it on server side? I want to have also ratings of players saved in my DB so login procedure will probably be necessary. When player connects to server server updates online players list. When he challenge another player and he accept server exchange ip`s(and ports? which port to use?) between players. Then they connect to each other and game begins. What is best practice for connection between server-android and android-android? Probably sockets, right? Is there any library for handling lost connection etc.? Which server do you recommend?

• ASP.NET Connections Fall 2011 Slides and Code

  - by Stephen Walther

  Thanks everyone who came to my talks at ASP.NET Connections in Las Vegas!  There was a definite theme to my talks this year…taking advantage of JavaScript to build a rich presentation layer. I gave the following three talks: JsRender Templates – Originally, I was scheduled to give a talk on jQuery Templates.  However, jQuery Templates has been deprecated and JsRender is the new technology which replaces jQuery Templates. In the talk, I give plenty of code samples of using JsRender.  You can download the slides and code samples RIGHT HERE   HTML5 – In this talk, I focused on the features of HTML5 which are the most interesting to developers building database-driven Web applications. In particular, I discussed Web Sockets,  Web workers, Web Storage, Indexed DB, and the Offline Application Cache. All of these features are supported by Safari, Chrome, and Firefox today and they will be supported by Internet Explorer 10. You can download the slides and code samples RIGHT HERE   Ajax Control Toolkit – My company, Superexpert, is responsible for developing and maintaining the Ajax Control Toolkit. In this talk, I discuss all of the bug fixes and new features which the developers on the Superexpert team have added to the Ajax Control Toolkit over the previous six months. We also had a good discussion of the features which people want in future releases of the Ajax Control Toolkit. The slides and code samples for this talk can be downloaded RIGHT HERE   I had a great time in Las Vegas!  Good questions, friendly audience, and lots of opportunities for me to learn new things!      -- Stephen
