• How can I use apt-get to resolve package dependencies when there are multiple versions in the repository?

  - by user1165144

  I've package a-package.deb which depends on b-package.deb in version 1.0. Everything works fine. But now a b-package in version 1.1 gets added to the repository. I'd suspect that apt-get installs the a-package and version 1.0 of the b-package. What really happens is, that a-package won't get installed: # apt-get install a-package Reading package lists... Done Building dependency tree Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: a-package : Depends: b-package (= 1.0) but 1.1 is to be installed E: Unable to correct problems, you have held broken packages. Is there a workaround to fix the behavior? Is there other software to use, that can handle the dependencies as defined?

• IIS Web Farm Framework servers are automatically set to "unavailable" even when they are healthy... And they never return to the available state!

  - by JohannesH

  I have 2 web farm configurations, one with 2 member servers and one with 3 member servers. I have health monitoring set up on both farms and the monitoring tool reports all servers as being healthy. However after a while all the servers are marked as being "Unavailable" and "Healthy" in the "Monitoring and Management" screen (in the "Servers" screen they are all listed with "Yes" in the "Ready for Load Balancing" column). Viewing the event log on both the web farm controller or any of farm servers doesn't reveal anything interesting. there are no warnings or errors in the period where the servers became unavailable. There are a couple of informational events about the worker process getting shut down due to inactivity but I don't hope this is the cause since that would mean that the farms will die during the night when the load is low. Am I missing something? EDIT: Btw, I think its very odd that the application pool shuts down on the servers since the health monitoring system is polling an aspx page on each server. Shouldn't that keep them going? EDIT2: Now I've also experienced this problem with the RTW version of Web Farm Framework 2.

• Protocol (or service publish/discovery) to detect devices in network

  - by Gobliins

  we connect some embedded devices in a network. What i am looking for now, is a way to find the devices IP and identify them. We work with Windows PC´s and i am about to write a C# tool that should do this. I thought about send a udp broadcast and in the ack i.e. is the device´s ip, which would mean the device needs a daemon runnig to assign an ip itself. Running a service (like a printer) on the device, and on the PC just lookup for the service. I read about some things like apipa, zeroconf, ipv4 local link, bonjour, dns-sd, mdns, bonjour; They can automatically assign ip´s and publish services in a network. My Question is, can someone recommend me what would be good for my task? -The protocol or Service should be low on ressource (memory/cpu usage) use. -Are there some standard protocolls to use? -Is DNS a good idea or would it be to ressource consumpting just for finding a device´s IP? -Should also work when no dhcp servers are around. edit: To clarify a bit: The IP configuration is automatic. The problem to focus is how to tell the PC which IP in the network (or a direct connection in this vase there would only be one) belongs to the device (identity).

• Duplicate forwarded messages in Blackberry when using BIS

  - by Avery Payne

  Our Setup External email arrives at a Postfix server, is scanned, and then forwarded via settings in transport (using the RELAY:[{ip-address}] for a given address) to an Exchange 2007 server. Some users are on Exchange, but a few are still on the Postfix server (they will be moved in the near future). IMAPS is provided for external connections via Dovecot; in-house, IMAP is provided for the Gateway and native MAPI is used for Exchange/Outlook. Blackberries are connected via BIS, which uses Dovecot as a reverse-proxy IMAPS service to connect to Exchange (when the mailbox exists on Exchange, otherwise it connects to the mailbox on the gateway). The Issue We have a user that, when they forward an email on their Outlook client, they get a duplicate of the original message on their Blackberry. When I say duplicate, I mean that they have a copy of the forwarded version of the message (i.e. their version of the message that they obtained hitting the forward button), and a copy of the original message that shows up at the same time. The expected behavior is to just see the forwarded message, not the forwarded message and a 2nd copy of the original message. We've only seen this with Outlook users that also have a Blackberry. Other IMAP clients, such as OS X Mail or Thunderbird, do not exhibit this behavior when connecting to the Exchange server; forwarded messages work as expected. The Questions what is causing this to happen? why does it only affect Outlook/Blackberry setups, and not TBird/Blackberry or OSX-Mail/Blackberry? how do we get it to stop, before people go insane and never forward messages again?

• how to build network across buildings ?

  - by Omie

  Hi ! I need some help in building a network between hundreds of computers spread across multiple buildings of my college. Yes, I'll be doing this as a part of my college project. Please see this image, it will give you enough idea of what I'm trying to achieve. http://i.imgur.com/rOohx.png All the computers in all buildings should be able to connect server. Once network is up, there will be a set of services over intranet and network use will be moderate. well, say there will be an email server and a http server. My point is, I cannot afford much of performance loss. It feels easy to connect computers inside 1 building to each other, however, I'm clueless as to how to connect all of them to server. I mean, just 1 cable won't be enough to connect 1 building to server, right ? How should I go with it ? I am not expecting detailed configuration. Just heads up will do :) Thanks

• Working with an external button box

  - by Scott

  I tried this question on Stack Overflow, but I was pointed here, so here goes: For a new project for myself, I am looking for a way to be able to (for example) open a pop-up window on my laptop, by pressing a button on an external device (to be build by myself, or at least bought) connected with USB. Basically I would be looking at something like a Arduino or Raspberry (IF I am looking in the right direction) with buttons on it, and as soon as I hit a button on the external box with physical buttons, a command activates on my laptop and for example opens a popup window in which I can input tekst. Does anyone know: 1) if it is possible to do this at all. 2) What equipment is needed for the external box, what programming is needed. I preffer .net (dot net) but maybe it can only be done with software from the external box. If anyone can point me in the right direction, like make/model of the external box or websites I would be very happy. I have knowledge of Visual Studio/.net but I am willing to learn other languages if .net is not an option for this project. Thanks in advance Scott PS: If anyone knows of some better tags, or at least knows what I mean and needs me to edit the question, please do tell me... I am new on Stack Overflow/Superuser.

• netbook screen stays black

  - by sam113101

  I have an acer aspire one netbook. The screen is black but the computer turns on (LED's are on, fan is spinning, etc.) By black I mean absolutely no backlight. I tried to remove the battery and power it on to "discharge" it (I read that on the Internet, not sure if that ever fixes anything), but no luck. I also tried to replace the RAM stick with another one (which I know for sure is working properly), still no luck. I tried to connect an external monitor and switch to it (fn + f5 on this particular model), still no luck, nothing on the external monitor. I read that flashing the BIOS could fix it (http://community.spiceworks.com/how_to/show/22042-acer-aspire-one-black-screen-of-death), I tried to flash it but basically it doesn't do anything when I power it on with the usb thumb drive. No blinking power button. To me it sounds like it might be a dead motherboard, a dead RAM slot (there's only one), or the BIOS thing. I would like to rule out the BIOS possibility, but I need help. The reason I ruled out the dead screen possibility is that it did not switch to the external display when I pressed fn + f5, am I wrong by assuming so? Thank you for your help.

• locale: What is the LANGUAGE variable used for? (and when?)

  - by seya

  I am trying to understand the locales used in Linux. On my Ubuntu 11.10 system locale puts out the following: LANG=en_DK.UTF-8 LANGUAGE=en_GB:en LC_CTYPE=en_GB.UTF-8 LC_NUMERIC="en_DK.UTF-8" LC_TIME="en_DK.UTF-8" LC_COLLATE=en_GB.UTF-8 LC_MONETARY="en_DK.UTF-8" LC_MESSAGES=en_GB.UTF-8 LC_PAPER="en_DK.UTF-8" LC_NAME="en_DK.UTF-8" LC_ADDRESS="en_DK.UTF-8" LC_TELEPHONE="en_DK.UTF-8" LC_MEASUREMENT="en_DK.UTF-8" LC_IDENTIFICATION="en_DK.UTF-8" LC_ALL= (en_dk is for using international day format, continental European number formatting (1.234,56) etc.) I think I understand what the LC_* family does, that LANG is the fallback if one of them is not set and that LC_ALL sets all of the LC_* variables to its value. What I don't know yet, is what LANGUAGE is used for. The notation en_GB:en reminds me of the Accept-Language HTTP header. With the settings above it would mean, British English is used, if a translation for it exists. Otherwise any existing English translation (en_US, en_AU, ..., whatever) would be used. Am I right so far? Also what programs actually obey the LANGUAGE setting? In how far is it different from LC_MESSAGES? Unfortunately, man locale only documents the LC_* family. And searching the web for 'linux locale LANGUAGE' or similar is a mute point. (Of course language is a word often used when talking about locales, and it may also be shown just in the output of locale without being discussed). Does anybody of you can help me out there?

• Difference between "bit-number" in filesystem and that in OS (like 32,64 bit)?

  - by learner

  I encountered 2 terms ,"FAT32", a file system and "Windows Vista 32 bit". I found that the meaning of a 32 bit OS is that that the OS deals with data in chunks of minimum size 32 bits. I don't quite understand the depth of that, but I figure ,every file in that system with that OS should have a minimum size of 32 bits. I also read that these 32 bits are used to hold data of files' location(reference) and details. Which of it is it? I have also read that 4 GB of RAM is all that is needed at the most if you're on a 32 bit OS. But I don't understand why. If there are 32 bits to hold info about files and their locations,there can be 2^32 possible combinations of it. But I have found in many places,2^32 is divided by 1024 thrice to get 4GB. Why? Did that 2^32 become equal to 2^32 bytes? And about filesystems I read a similar explanation for what 32 means in FAT32. It is supposed to mean that 32 bits are used to number file system block. Now how is different from the number before the OS?

• How do you get linux to honor setuid directories?

  - by Takigama

  Some time ago while in a conversation in IRC, one user in a channel I was in suggested someone setuid a directory in order for it to inherit the userid on files to solve a problem someone else was having. At the time I spoke up and said "linux doesn't support setuid directories". After that, the person giving the advice showed me a pastebin (http://codepad.org/4In62f13) of his system honouring the setuid permission set on a directory. Just to explain, when i say "linux doesnt support setuid directories" what I mean is that you can go "chmod u+s directory" and it will set the bit on the directory. However, linux (as i understood it) ignores this bit (on directories). Try as I might, I just cant quite replicate that pastebin. Someone suggested to me once that it might be possible to emulate the behaviour with selinux - and playing around with rules, its possible to force a uid on a file, but not from a setuid directory permission (that I can see). Reading around on the internet has been fairly uninformative - most places claim "no, setuid on directories does not work with linux" with the occasional "it can be done under specific circumstances" (such as this: http://arstechnica.com/etc/linux/2003/linux.ars-12032003.html) I dont remember who the original person was, but the original system was a debian 6 system, and the filesystem it was running was xfs mounted with "default,acl". I've tried replicating that, but no luck so far (tried so far with various versions of debian, ubuntu, fedora and centos) Can anyone clue me in on what or how you get a system to honor setuid on a directory?

• Moving an external hard drive while running

  - by user1108939

  I mean physically moving the drive around. I've never dealt with external hard drives before. Just plugged this wd mypassport to test the transfer rate. At one point I 'safely ejected' the drive. A minute later I decide to check the underside of the drive, not realizing the disk is still spinning. I lift the drive, rotating my writs about 70 degrees to the left... I hear a sequence of three high pitched sounds. I couldn't determine whether that was an indication beep by an internal security feature or the head scratching the plate (oh god...). Drive stops and usb power is disconnected. I reconnect it - it shows up fine - reads/writes. The drive was not reading/writing when i moved it. Did I damage my drive? Are these things that fragile? I thought them to be at least as durable as a standard 2.5" internal drive. Am I mistaken?

• Will the removal of NAT (with the use of IPv6) be bad for consumers? [closed]

  - by Jonathan.

  Possible Duplicate: How will IPv6 impact everyday users? (World IPv6 Day) As I understand when we have finally made the switch to IPv6 not only will NAT be unnecessary but it is incompatible with IPv6? Will that mean that ISPs will have to serve multiple IP addresses per customer? Will they provide a range of addresses for each customer or as each device connects will they get an IP address that isn't necessarily near that of the other devices in their house? But overall will this be bad for the Internet users? as surely it will allow ISPs to see exactly how many devices are being used, and so allow them to charge for the use of additional IP addresses? And then if that happens, what happens when you try to connect an extra device to your network? Will it simply not get an IP address? In my home we have about 15-20 devices connected at once, but for places where there are hundreds of devices, it seems like the perfect opportunity for ISPs to charge more? I think I may have it completely wrong, so is there somewhere where there is an explanation of who things will work when IPv6 becomes the norm?

• Strange 3-second tcp connection latencies (Linux, HTTP)

  - by user25417

  Our webservers with static content are experiencing strange 3 second latencies occasionally. Typically, an ApacheBench run ( 10000 requests, concurrency 1 or 40, no difference, but keepalive off) looks like this: Connection Times (ms) min mean[+/-sd] median max Connect: 2 10 152.8 3 3015 Processing: 2 8 34.7 3 663 Waiting: 2 8 34.7 3 663 Total: 4 19 157.2 6 3222 Percentage of the requests served within a certain time (ms) 50% 6 66% 7 75% 7 80% 7 90% 9 95% 11 98% 223 99% 225 100% 3222 (longest request) I have tried many things: - Apache2 2.2.9 with worker or prefork MPM, no difference (with KeepAliveTimeout 10-15) - Nginx 0.6.32 - various tcp parameters (net.core.somaxconn=3000, net.ipv4.tcp_sack=0, net.ipv4.tcp_dsack=0) - putting the files/DocumentRoot on tmpfs - shorewall on or off (i.e. empty iptables or not) - AllowOverride None is on for /, so no .htaccess checks (verified with strace) - the problem persists whether the webservers are accessed directly or through a Foundry load balancer Kernel is 2.6.32 (Debian Lenny backports), but it occurred with 2.6.26 also. IPv6 is enabled, but not used. Does the issue look familiar to anyone? Help/suggestions are much appreciated. It sounds a bit like a SYN,ACK packet getting lost or ignored.

• Potential impact of large broadcast domains

  - by john

  I recently switched jobs. By the time I left my last job our network was three years old and had been planned very well (in my opinion). Our address range was split down into a bunch of VLANs with the largest subnet a /22 range. It was textbook. The company I now work for has built up their network over about 20 years. It's quite large, reaches multiple sites, and has an eclectic mix of devices. This organisation only uses VLANs for very specific things. I only know of one usage of VLANs so far and that is the SAN which also crosses a site boundary. I'm not a network engineer, I'm a support technician. But occasionally I have to do some network traces for debugging problems and I'm astounded by the quantity of broadcast traffic I see. The largest network is a straight Class B network, so it uses a /16 mask. Of course if that were filled with devices the network would likely grind to a halt. I think there are probably 2000+ physical and virtual devices currently using that subnet, but it (mostly) seems to work. This practise seems to go against everything I've been taught. My question is: In your opinion and  From my perspective - What measurement of which metric would tell me that there is too much broadcast traffic bouncing about the network? And what are the tell-tale signs that you are perhaps treading on thin ice? The way I see it, there are more and more devices being added and that can only mean more broadcast traffic, so there must be a threshold. Would things just get slower and slower, or would the effects be more subtle than that?

• Does cloud computing offer this? [closed]

  - by TheBlackBenzKid

  I have some newb questions I want answering please about cloud hosting - we are currently looking at Rackspace and getting a windows box. This is the situation: We have 15 computers in our office. We have 3 printers, some wifi and some network plugged. We have a standard router and the office share things via dropbox. The computers are not on Windows SBS or something similar. We want a cloud hosting solution that will offer User can login on any machine in the office and see the machine software User can login on any machine in the office and open Outlook and their emails and signature will be on exchange automatically A shared company folder on the network All printers automatically installed on the network Users can login remotely to access emails via the web At the moment we have a network company saying we need Xeon server in house with backup and psu and Windows SBS with license for each machine and also we need cabinets and cabling setup and also load balancers and modification of our DNS for emails. My question is this. Can cloud offer this? Can we have a server in the cloud that does this? Is it possible I mean the computers would be wireless connected to this cloud and you turn the machine on and its hosted?

• How do I use a list of filenames to find a folder on my hard drive, that contains most matches of these filenames?

  - by Web Master

  I need a program that will use a list of file names to find a folder on my hard drive that contains the most of these filenames. Long story short I made a giant map. This map was live and got ruined. New map data files have been generated, and previous map data files have been altered. What does this mean? This means file sizes have been changed, and there will be new files that have never been in the backup folder. Some files map files could also have been generated in other projects. So there could be filenames on my computer not associated with this due to the way the files are named when created. So If I take an indidual file for example "r.-1.-1.mca" This file could show up on my hard drive 10 times. Anyway, the goal is to take 100 map files, turn them into a list, and then search the hard drive and find the folder that has the highest count of matching map file names. Can anyone figure out a way to do this? I am thinking about manually searching for every single file.

• What is the best time to set the IP address for a server headed to a server colocation facility?

  - by jim_m_somewhere

  What is the best time to set the IP address for a server? I have a server that I am going to install the OS on and then I am going to send it to a server colocation facility. The server is going to have Internet facing services (www, email, etc.) I can set up a "fake" IP address during install (by fake I mean private as in RFC 1918) and change the "fake" IPs to the real IPs once I set up the colocation service. The other option is to set up the colocation service...wait for them to give me the "real" IPs and use them during the OS install. The ramification are that...if I use "fake" IPs during install...I will have to wait before I set up things like SSL certs. If I wait for IPs from the colocation provider...then I can set up SSL certs that use the "correct" (as in "real") IP addresses...no changes to the certs until they expire. Do the "gotchas" of changing an IP address on a server outweigh the benefits of a quick install? The other danger with using "fake" IPs is that I could make a mistake when I go through the various files to change the IP address to the "live" IP address. Server OS: CentOS 6.2 or CentOS 6.3, 64 bit. Apps: Apache 2.4.X httpd, MySQL 5.X (will eventually use replication)

• Cheated!! Please help

  - by Rohit K

  I was experiencing some hard disk problem with my HP laptop. It showed at bootup as system diagnostics are run -- Smart Drive attribute failed. Also i repeatedly got a warning for imminent hard drive failure and thus to back up my data. So i gave my laptop to authorized HP service center for repair. They formatted my hard disk and installed a pirated copy of Win 7 Ultimate (i earlier had genuine Win 7 Home Premium running on my laptop) and they told me they cover out-of-warranty issues and even charged me for it. What's worse is that the hard drive problem is still present and all i am left with is an illegal copy of windows which i think also voids my warranty. What should i do? I mean i did purchase a genuine Windows with my laptop, so there must be some way to reinstall it even when i don't have a genuine copy now on my machine. Can't i get legit keys to reinstall Win 7 from Microsoft because i did pay for the software when i purchased my machine. And if that's not possible, how can i claim warranty and get my hard disk replaced by HP?

• Notepad++ FTP best solution

  - by yoda

  Hi, I use Notepad++ for more than 2 years now, and there's only 1 thing that it needs for me to be perfect: a actually-working-ftp-plugin. It has an ftp plugin, written by someone that meanwhile left the project (by meanwhile I mean a long time ago), and since then nobody had courage to improve it. The problem is that it does't handle connections very well. Sometimes it lost connection with the server and literally "blocks", others don't save the files properly, other only load half of the ftp files, etc etc .. My question is: Is there a way to use ftp and notepad++ (without using its build-in ftp or a ftp client like filezilla)? I've tried using NetDrive, but it gets stuck sometimes (makes the editor crash), and everytime the temporary file is refreshed by windows / NetDrive, it will load the new file without asking and skip the pointer to the end of the file (very very very annoying). In case you know how to make the built-in notepad++ ftp plugin work at 100%, I'd be much more happy! I'd like to have some feedback from you guys :) (I'm using Windows Vista) Thanks in advance!

• unmanaged VPS account; Beginners questions

  - by pesar2

  I have a classified website which uses MySQL, PHP, Solr (java) etc etc... I wonder where I should start after purchasing a VPS package from my provider. There are first of all several packages, I am going with Linux because as far as I know it is the most stable system. But I have never used Linux before! What is Ubuntu, and which version of it should I get? Whats 64bit Ubuntu then? How do I install php, javascript, mysql, java and all that? What is debian, do I need it? What is apache, do I need that? And most importantly, what applications do I need, that I must have? (I mean applications which a beginner would never know was needed, what do you recommend?) After getting the vps, how do I even access it? Do I type in some kind of IP into the browser? Or is it by ftp program? How do I access the so called "terminal"? Please guide me, I am completely new to Linux and VPS! Thanks

• what is best multi-server configuration with OpenVPN

  - by sebut

  We have a number of Database severs running MongoDB on Debian plus a number of Application servers also on Debian. The db servers hold replicating db clusters, so they need to talk to each other. Application servers need to talk to all db servers (for reasons of fault tolerance). The servers are potentially spread across multiple hosting centers, so we need secure channels between all servers. The number of servers is bound to grow, so we need a VPN solution that's easy to maintain and expand. This is why I feel that SSH that we use for testing might not be up to the task and OpenVPN seems the way to go. I have ruled out TAP, since I understand that this would mean all traffic going to all the servers - perhaps this is a misunderstanding and TAP acts more like a switch? With TUN devices I imagine that all DB servers would live in their own separate subnet, they would also need a client configured to be able to connect to each of their peers. The application servers could live in a common subnet range with a client config only. Does this sound like a reasonable setup? Strangely, on the web I did not find anything about multi-server with OpenVPN. Thanks for all insights and ideas!

• Did Windows 7 Startup Repair trash My Documents?

  - by Metaphile

  Earlier today, I rebooted my computer. Partway through the boot process, it shut down suddenly. When I tried again, I was prompted to run Startup Repair, and I did. Afterwards, my computer booted normally and everything seemed to be in order. Then I noticed that my My Documents folder contains a mix of old and new files. On closer inspection, it appears that Windows has reverted my system to a previous state. Two things puzzle me: 1) According to Microsoft, "System Restore does not affect personal files, such as e-mail, documents, or photos [...]", yet many of my personal files have been affected. 2) Why were some things reverted, but not others? I had recently reorganized a bunch of files in My Documents. The reverted directory structure seems to be a hybrid of old a new, with a lot of new stuff missing. It's hard to say for sure, but it looks like the stuff that's missing would have been in conflict (two folders with the same name, for example), and Windows favored the old stuff. Is this normal behavior for Startup Repair/System Restore? To modify personal files, I mean? Is there a pattern to the mess it's made of My Documents?
