• Copying large files from USB devices to the internal hard drive fails on Mac OS

  - by John M. P. Knox

  I have a second-generation 13" MacBook Air running Mac OS X 10.6.6 with a 2.13 GHz processor, 4 GB of RAM, and a 256 GB SSD hard disk. I often get failures when I attempt to copy a large file or large collection of files from an external USB drive (typically a "Firewire" generation Drobo) to the internal drive. The failure behaves almost exactly as if I had pulled the USB cable from the computer in mid-transfer. I get a warning that I have removed the hard disk improperly. After this event, the drive no longer appears mounted in the finder, and I have to unplug and reinsert the USB cable to mount the drive again. I have also seen a similar problem when using Aperture 3 to import a large number of photos and videos from a USB Compact Flash card reader. The import will fail and I will have to unplug the Card Reader and import the missing items. Oddly, reversing the direction of the copy seems pretty reliable. I've never had a problem copying a large file to a USB device, meaning that I have quite a few large files which are stranded on my Drobo. Model Identifier: MacBookAir3,2 Boot ROM Version: MBA31.0061.B01 I have seen a similar issue reported on Apple's website: http://discussions.apple.com/thread.jspa?threadID=2648590&tstart=0 The only suggested resolutions there seems to be switching to another form of connectivity (e.g. firewire, which does not exist on MacBook Air), or downgrading to Mac OS 10.6.4, or reverting the USB kernel extensions to the 10.6.4 versions: http://discussions.apple.com/message.jspa?messageID=12566073#12582956 I'm not too keen on the idea of downgrading kernel extensions. Does anyone know of a hardware revision without this issue that I can trade up to? Are there any other potential solutions out there?

• Windows Vista claims wireless key is the wrong length

  - by humble coffee

  A family member of mine is house sitting and has been given the details of their wifi. The access point is an Airport Express, it has WEP encryption (I think) and they've been given a passphrase to use. I know it's a passphrase and not the encrypted key as it's an English word. The passphrase is 10 characters long. The problem is that Vista complains that it's not a valid key as it must be a 5 or 13 character non-hex key or a 10 or 26 character hex key. (From what I've read this suggests the encryption is WEP?) I've found a couple of suggested solutions, but I'm not actually at the house at the moment so I wanted to make sure I have a good chance of getting it to work when I'm there but have no internets to ask. Solution 1: Vista needs to be told explicitly what kind of encryption and key is being used. Specify in the connection settings that you are using WEP and that it is a "shared key". Solution2: Try converting the passphrase to hexadecimal using an ASCII-hex converter and entering that.

• Windows xp recovery console without Ntfs.sys? (0x00000024 BSOD)

  - by Kalle

  I have two physical disks in a computer, for simlicity lets call them C and D. C: got Windows XP and D: got some data. The problem is that whenever i have D: connected i can't boot windows. I get some BSOD called 0x00000024/NTFS_FILE_SYSTEM. Same thing if i boot up windows with D: disconnected and then connect it once windows has loaded. The KB article about this problem says that i have to run chkdsk but i can't get to somewhere where i can run this because i get a BSOD whenever the disk is connected! Even the recovery-console BSODs if D: is connected. The final option in the KB is to boot the computer on Windows 2000 Setup disks where you edit some file to manually disable the ntfs.sys driver and then run chkdsk. The problem is that i don't have any floppy drive. Is there any way to boot the built in recovery console with ntfs.sys disabled or to burn the floppy version to a cd after you've extracted and modified it on the harddrive? Right now the Windows xp bootable floppy creator(2) is asking me which floppy drive to extract to which i can't answer because i have none :/ Other solutions to the root problem is also appreciated :) (2) ht tp://www.microsoft.com/downloads/details.aspx?FamilyID=55820edb-5039-4955-bcb7-4fed408ea73f&displaylang=en

• Getting started with webserver clustering.

  - by Ernie

  I work for a small ISP, and we host about 250 domains and all the stuff that goes along with that: DNS, mail, spam filtering, and backups. Currently, we have separate DNS servers (two of them) and mail servers (outgoing mail is actually on the secondary DNS server, but was previously on its own server). In the past, this was done as an insurance measure. The last thing we need is for some doofus (usually yours truly) to hose a server, taking out DNS and mail right along with it, or for spammers to jam our incoming SMTP server, preventing outgoing mail from being sent too. In the past, this was a problem, and our servers were set up the way they are now to combat it. However, clustering solutions like Sun's Cobalt RAQ (in days of olde) and Virtualmin appear to cater to an all-in-one approach, then deal with failures through redundant servers. I have avoided this thus far, but we've been using Virtualmin on our web server for a while now, and I'd like to expand into using it for a high availability cluster. Our networking partner has recently built a datacenter that has eliminated all of our other bugaboos like network, cooling, and power issues, so now the only thing left to go wrong is me hosing a server, which happened earlier this month. One of the bigger reasons we've avoided going this route is because our hardware requirements aren't particularly high. One server easily handles all the sites we host (most of them are flat sites). Also, load-balancing routers tend to be expensive and complicated. All that I'm really expecting to do is building a two-node cluster for redundancy so that when I hose a server (however rare that might be), we're not out for 8-12 hours while I rebuild it. What I need to know is how to get started, and if I'm really in a position to bother with this kind of thing at all.

• Windows Bluescreen - atikmpag.sys

  - by Mochan

  Information Name: atikmpag.sys bluescreen (BSOD or BlueScreen of Death) Error code: 0x00000116 Appears when: Playing games, watching videos Can be reproduced: Yes Cause: Graphics Card is the main assumption System Specifications Before we begin - I will inform you of my specifications. OS: Windows 7 x64 Home Edition Model: Dell Inspiron 15R Special Edition (aka Inspiron 7520) (Add 2GB of RAM to the model linked) Hard Drive: 1TB CPU: Intel Quad-Core i7 Sandy Bridge (I think) Processor at 2.10GHz (I think it can be clocked to 3GHz?) RAM: 6GB (I think 1 x 4GB and 1 x 2GB) Display: 15.6" HD (1366x768) Graphics: AMD Radeon HD 7500M 2GB Details So now that you know some basics about my computer, I'll get to the problem. Being an Ubuntu user I hardly use Windows, but occasionally I do. Like to run Skyrim and other games incompatible with Linux and WINE. The new Sims 3 Seasons patch is also now not supported. When playing these two games and other ones, theoretically. I have also heard others saying that while watching HD movies and video series it also happens. While watching the bluescreen as it happens, I see it is the 'atikmpag.sys' error. I have not installed much and nothing significant. I think I have downloaded Skyrim, Firefox and The Sims 3. I haven't done much more... since Ubuntu is definitely the best in comparison! (No hate, just a joke :P). I can reproduce it easily (just by running a game for less than a minute). It is always there each time, but it's never at a specific time or anything. So far I have found that it may be caused by lack of power to the graphics card, or it may be damaged or fried. Since I've had the computer for a mere 4 months (and have had other problems with it also). I have contacted Dell but they are useless beyond belief. Anyone with any information, solutions or details are encouraged to share your knowledge, as it would be immensely appreciated.

• Problems with Vista loading a temporary user profile.

  - by Joe

  I'm having a problem in Vista. My machine has four users, one for each of us in the house. Whenever a user logs in before me, they log out, and then I log in, Vista loads a temporary profile for me. However, if I restart and log in, I get into my profile no problem. Two errors are written to the event log (see below), and I've searched everywhere for solutions. 1: Windows was unable to load the registry. The problem is often caused by insuff. memory or insuff. security rights. DETAIL - The process cannot access the file because it is being used by another process. for C:\users\joe\ntuser.dat I've got plenty of disk space and memory. 2:Windows cannot load the locally stored profile. Possible causes of this error include isufficient security rights or a corrupt local profile. DETAIL - The process cannot access the file because it is being used by another process. Thanks!

• Java applet class never found

  - by Andrew

  I am having a problem with the java plugins of all three major browsers: chromium, firefox and Internet Explorer. The issue is that applets will always fail to load and yield errors no matter what website or what applet I am trying to use. I can not see any of the example applets on oracle's website; I can not launch the minecraft browser applet; nor can I launch any applet across the web using any browser. I always receive a "class not found:AppletClassHere.class" error. I know that my browser plugin must be working correctly because I can launch the Cisco Nac applet each time I connect to my network and I can launch my own simple applets offline. I am connecting to the internet through a vpn in case that is important. It also seems like a lot of other people I know are having this issue. Re-installing the plugin does not appear to fix the issue. I am asking this question to find out the cause of this problem, and any possible solutions. Thank you.

• Proper Network Infastructure Setup DMZ, VPN, Routing Hardware Question

  - by NickToyota

  Greetings Server Fault Universe, So here's a quick background. Two weeks ago I started a new position as the systems administrator for an expanding health services company of just over 100 persons. The individual I was replacing left the company with little to no notice. Basically, I have inherited a network of one main HQ (where I am situated) which has existed for over 10 years, with five smaller offices (less than 20 persons). I am trying to make sense of the current setup. The network at the HQ includes: Linksys RV082 Router providing internet access for employees and site to site VPN connecting the smaller offices (using an RV042 each). We have both cable and dsl lines connected to balance traffic (however this does not work at all and is not my main concern right now). Cisco Ironport appliance. This is the main gateway for our incoming and outgoing emails. This also has an external IP and internal IP. Lotus domino in and out email servers connected to the mentioned Cisco gateway. These also have an external IP and internal IP. Two windows 2003 and 2008 boxes running as domain controllers with DNS of course. These also have both an external IP and internal IP. Website and web mail servers also on both external and internal IPs. I am still confused as why there are so many servers connected directly to the internet. I am seriously looking to redesign this setup with proper security practices in mind (my highest concern) and am in need of a proper firewall setup for the external/internal servers along with a VPN solution about 50 employees. Budget is not a concern as I have been given some flexibility to purchase necessary solutions. I have been told Cisco ASA appliance may help. Does anyone out in the Server Fault Universe have some recommendations? Thank you all in advance.

• Network Explorer Intermittently Fails to Display all Computers in Work Group

  - by graf_ignotiev

  I run a small computer lab of 10 computers and occasionally, when using the network explorer (a.k.a Network Browser) some or all of the remote computers will fail to appear. If I try to access a remote computer by its name I get an unspecified error (code 0x80004005), but I am still able to access it with the computer's IP address. The strangest part is that the problem will inexplicably go away after waiting awhile. Each computer is running Windows 7 x64 Enterprise and has identical hardware, software and configuration. They are all on the same subnet and in the same workgroup. I've spent days researching the problem and have tried the following solutions: Updated the BIOS, chipset and network adapter drivers Changed Power Settings in Network Adapter Properties so that the computer will not turn it off Disabled the Computer Browser service Changed the DHCP node type to broadcast Reviewed the Event Viewer logs Steps 3 and 4 have seemed to help the problem a little bit, but not completely. I'm beginning to suspect that the problem might lie with our router which is a ZyXEL ZyWALL 2WG, as the packets sent by Network Discovery may not be returning in time, but I wanted to get some perspective in the issue before I went any further.

• Checkpoint VPN-1 R60 and Windows 7 64 Bit Client

  - by Mohit

  As per my knowledge of checkpoint VPN-1. My company is using checkpoint VPN-1 R 60 ( I guess as I dont know how to check server version) Firewall(VPN Server). Now the problem is that I installed Windows 7 64 bit. But, after my research I found that there are not even one client (SecuRemote/SecuClient) for Win7 64 bit, when Firewall or server is R60. I thought of some open source solutions. Can you guys please suggest me some with the configuration required. As of now, I know the IP of the server. I know my username and password using which I connect and that is not my domain password. that i can confirm to you guys. I am not a network guy. I am more of a developer. But, I need some help in this.So, let me know if I can provide you more details. Please please i need urgent help on this.

• Swapping Function (Fn) and Control (Ctrl) Keys on Lenovo ThinkPad W500

  - by Howiecamp

  I'd like to swap the Fn and Ctrl keys on my ThinkPad W500 (like many others!). I wanted to comment on http://superuser.com/questions/35228/how-can-i-switch-the-function-and-control-keys-on-my-laptop and StackOverflow question 514781 (please Google it because I don't have enough rep to include 2 hyperlinks) but I don't have enough rep to do so to comment. Numerous folks (in both the above questions and on other Google searches) indicate that Windows doesn't register the Fn key as a keypress but using a tool that gives the ASCII value of a keypress (visit www mihov com / eng / am.html) I see the Fn key returning FF (perhaps FF in this case means 'not registered'). I also see that keys like Ctrl register with one ASCII code when pressed alone and another when pressed in combo with another key. Fn will only register when pressed alone, so Windows definitely isn't seeing the combo. This took a solution like AutoHotKey off the table. I ran KeyTweak (which shows you the hardware scan codes of a keypress and the Fn key registerd as 57443). Using this program I remapped Fn to the Ctrl key; this worked perfectly. However, I suspect that because of the issue in #1, the combo of, for example, Fn + C did not execute a copy. Short of retraining my pinky I'm actually considering removing the keyboard and resoldering the connections to swap those keys. I'd love to get some input as to the root technical issue(s) and possible solutions here. Thanks

• After reinstallation, Disk Cleanup disappears when I click OK.

  - by James

  After I reinstalled Windows 7, Disk Cleanup stopped working. I can start Disk Cleanup and select the drive to clean, but when I click on the OK button, the window disappears. Any solutions?

• Database types for customer analytics

  - by Drewdavid

  I am exploring a paid solution to start providing better embedded, dashboard-style analytics information to our website customers/account holders, but would like to also offer an in-house development option to our team. The more equipped I am with specifics (such as the subject of this question), the better the adoption rate from the team (or so I have found), regardless of the path we choose Would anyone care to summarize a couple of options for a fast and scalable database type through which we would provide the following: • Daily pageviews to a users account pages (users have between 1 and 1000 pages) • Some calculated/compounded metrics (such as conversion rate, i.e. certain page type viewed to contact form thank you page ratio) • We have about 1,500 members (will need room to grow); the number of concurrently logged in users will for the question's sake be 50 I ask because our developer has balked at providing this level of "over time" granularity (i.e. daily) due to the number of space it would take up in a MYSQL database To avoid a downvote I have asked specifically for more than one option, realizing that different people will have different solutions. I will make amendments to my question if so guided by answering parties Thank you for sharing your valued answers :)

• Avoiding DNS timeouts when a dns server fails

  - by Neil Katin

  We have a small datacenter with about a hundred hosts pointing to 3 internal dns servers (bind 9). Our problem comes when one of the internal dns servers becomes unavailable. At that point all the clients that point to that server start performing very slowly. The problem seems to be that the stock linux resolver doesn't really have the concept of "failing over" to a different dns server. You can adjust the timeout and number of retries it uses, (and set rotate so it will work through the list), but no matter what settings one uses our services perform much more slowly if a primary dns server becomes unavailable. At the moment this is one of the largest sources of service disruptions for us. My ideal answer would be something like "RTFM: tweak /etc/resolv.conf like this...", but if that's an option I haven't seen it. I was wondering how other folks handled this issue? I can see 3 possible types of solutions: Use linux-ha/Pacemaker and failover ips (so the dns IP VIPs are "always" available). Alas, we don't have a good fencing infrastructure, and without fencing pacemaker doesn't work very well (in my experience Pacemaker lowers availability without fencing). Run a local dns server on each node, and have resolv.conf point to localhost. This would work, but it would give us a lot more services to monitor and manage. Run a local cache on each node. Folks seem to consider nscd "broken", but dnrd seems to have the right feature set: it marks dns servers as up or down, and won't use 'down' dns servers. Any-casting seems to work only at the ip routing level, and depends on route updates for server failure. Multi-casting seemed like it would be a perfect answer, but bind does not support broadcasting or multi-casting, and the docs I could find seem to suggest that multicast dns is more aimed at service discovery and auto-configuration rather than regular dns resolving. Am I missing an obvious solution?

• Cisco Pix 515 ip addressing

  - by Rickard

  I have just gotten my hands on a Cisco Pix 515 (not 515E) with 3 interfaces, and are just about to start some labs. In my lab, I am using a real life scenario from an actual setup at work. As I have no access to the device at work, I am simply trying to replicate the scenario by trial and error. At work, we are given two IP addresses from the provider, which is 1-to-1 nated addresses. The addresses we are allowed to use are: 10.131.35.4-5/29 Now, we have 3 servers on a DMZ, 192.168.2.2-4/24 and 17 client computers on 192.168.1.100-117/24 aswell as some static addressed devices on 192.168.1.8-18/27 My question is, how would I best set up so that the machines on the DMZ get's translated to 10.131.35.4 and the machines on 192.168.1.* will be translated to 10.131.35.5 I don't expect or want anyone to give me a fully functional config, I may learn from it, but I'd prefer to just have some advices or maybe a guide on how to set it up. I hope someone can shed some light over my situation, have been looking through google but I guess I don't the searchwords I'm using isn't too good as I can't find any good clues. THank you very much! PS. Maybe I should add, I am not unfamiliar with the Cisco CLI, as I prefer using that before any gui's. So not really looking for any solutions for the ASDM. DS.

• Software mirroring (RAID1) versus "Fake Raid" for new Windows 7 install

  - by kquinn

  I've just ordered two new hard drives for my main desktop and a copy of Windows 7 Professional 64-bit. I'd like to do a clean install of Win7 onto the new drives (leaving my old XP Pro boot partition around for a while in case something goes disastrously wrong, etc.). I want to have them set up in mirrored (RAID-1) mode. My understanding is that Win7 Pro can do software mirroring, but can I set this up directly at install time? If so, how? Note that I'd like the disk to be split into three partitions (OS/Apps&Data/Bulk data), all of which should be mirrored. Would it be better (more reliable or faster) to use my motherboard's hardware RAID support? My motherboard is an older nVidia nForce 680i SLI, which is not the most stable of motherboards, and I'm not sure how trustworthy its RAID1 configuration might be (or if Win7 could even detect and install onto a hardware-mirrored volume). Also, the performance characteristics of RAID1 are rather different than RAID0 or RAID5, and I'm wondering if Win7's software mirroring might actually be faster than hardware RAID1 (for example, I'm more of a Unix admin when I have to wear the sysadmin hat, and I've had great success deploying ZFS; most hardware RAID1 implementations have to read both disks and compare results to look for data errors, but ZFS can read from only one disk in the mirror and just use the built-in checksum, meaning it can have up to 2x the number of reads in-flight, as long as there's no data corruption). Edit: Okay, my question about whether Windows 7 can do software mirroring has been answered, and it can. I'm still unsure whether Windows software RAID or my motherboard's hardware "fake RAID" function is a better choice, though. Remember, I'm only interested in mirroring -- not the more complicated striping or parity operations that generally show the poor performance of crappy motherboard RAID solutions.

• Performance Test and TCP tuning

  - by Mithir

  We are in the process of performance testing an application which receives tcp requests converts them to soap requests (WCF-httpBinding) which other services work on. The server is Windows Server 2008 R2. The TCP requests are received by TcpListener instance (.NET C#). There are 3 http-binded WCF services running on the same server. We have built a performance test client which goal is to simulate multiple concurrent requests(each request has to be different and recognizable by the application). We built a test running 150 requests that run on the same time (by 150 different threads), and we noticed straight away that some requests get the TCP connection slowly, but once they get it, they act fast. A single request writes twice on the same connection- request and an application ack. Although a single request+ack can take about 150ms, the 150 test takes about 7 seconds. The Problem When we try to run this test from 2 different computers we lose requests. some clients requests are getting no connection was made because the target machine actively refused it So I got here and got convinced it was because of the backlog. I changed the TcpListener parameters and did the registry AFD backlog changes written here but it still didn't work, so I inserted all of the TCP tuning suggested plus some netsh commands which were recommended, but still no change, we still get that error. Is there anything else I need to know? Are there any other solutions?

• Windows 8, IIS8 how to make PHP imagick work

  - by Laci K

  I'm new to IIS server before IIS for 6 years I used Apache 2.X and with Apache imageMagick and its PHP module imagick worked just fine even with x64 version of PHP and Apache 2.4 and imageMagick. I tried to make imagick to work with IIS8 but it wont work. I always get the typical PHP startup warning in my log PHP Startup: Unable to load dynamic library 'C:\Program Files (x86)\iis express\PHP\v5.4\ext\php_imagick.dll' - %1 is not a valid Win32 application. in Unknown on line 0 And the next thing why is IIS loading php from IIS express folder if I have php in the program files? But actually I dont care until it works :) So what I did so far I unistalled imageMagick 6.7.X 64bit version and installed the latest x86 version, tested it in command line and it worked, than I looked up on net the latest imagick DLL which was I think the 3.1.0RC2 (founded here http://www.peewit.fr/imagick/) than I copied the dll to PHP's ext folder than edited php.ini and added the imagick to the dynamic extensions after that I restarted IIS and than nothing :( I got the error which I wrote earlier. Today I installed PEAR package Installer because I read somewhere that someone made it work with it but he also mentioned, that he needed to comply wincache too. Isn't there any easier solutions to make it work? Could someone maybe write me a step by step guide how to make this work.

• Cannot click send button in Outlook (+ Exchange) for unknown addresses

  - by Graphain

  Hi, I have a very unusual problem. I have Outlook 2010 connected to Exchange 2010. This can send emails perfectly to known addresses (that is, addresses in the address book or ones that have been sent to previously). However, if I put in an address that is unknown, I cannot actually click the Send button in Outlook. (it simply does nothing). Corresponding to this I get errors in the Event Log for each Send click stating "The connection to Microsoft Exchange is unavailable. Outlook must be online or connected to complete this action.". However, Outlook shows as connected the whole time, pings do not break, and I have no reason to suspect it has lost connection. To further complicate matters, Outlook is fine on all other PCs, and this was all perfect until I installed BitDefender on the PC in question and the Exchange Server. Outlook was still fine on these other PCs while BitDefender was installed, but I have removed it from the PC in question and the Server just in case (no success). Summary: Outlook encounters Exchange connectivity issues when sending to unknown (new) email addresses that prevent the Send button actually working at all. This is isolated to one machine and occurred after installation of AV/Firewall software which has since been thoroughly removed. If you have any potential solutions I'd love to hear them, as I will be resorting to reformatting the PC in question, and probably removing Exchange because I'm sick of its issues if I cannot resolve this soon. Big thanks for any help.

• Multicast image restoration with adaptive speed

  - by Clinton Blackmore

  I'm curious to know if there are any tools for restoring disk images (or even transferring files) via multicast -- for any platform, especially if the project has source available -- where the multicast rate adjusts itself on the fly. On the Mac, all multicast solutions I am aware of (such as Deploy Studio, and NetRestore before it) make use of multicast ASR (apple software restore), which has one glaring deficiency -- you have to set the multicast speed before you start sending a disk image over the network, and that speed is locked in. Either your clients can keep up and restore, or they can't*. It seems to me that it must be possible for the multicast server to adjust the data rate, so you basically say "start sending this image", clients connect, and, if they can't keep up, they tell the server so it slows down. (Likewise, I'd expect the server to try speeding up if no client is having difficulties keeping up, and I'd expect to be able to cap that maximum throughput so that other network activities can go on without being resource starved.) So, what sort of tools are out there? For Linux? Windows? Is there something for the Mac I've overlooked. [It just kills me that it is true that, by the time you get multicast up and going at a good speed to restore a lab, you could've unicasted the data to all the computers and be done.] * There is a little leeway involved. I think individual clients can say, "I missed a little bit of data" and get it, and they can opt to listen in the next time the image is sent over the network, but on the whole, if they missed it the first go round, you have to image the machine again, and there is no time savings.

• Architecture for highly available MySQL with automatic failover in physically diverse locations

  - by Warner

  I have been researching high availability (HA) solutions for MySQL between data centers. For servers located in the same physical environment, I have preferred dual master with heartbeat (floating VIP) using an active passive approach. The heartbeat is over both a serial connection as well as an ethernet connection. Ultimately, my goal is to maintain this same level of availability but between data centers. I want to dynamically failover between both data centers without manual intervention and still maintain data integrity. There would be BGP on top. Web clusters in both locations, which would have the potential to route to the databases between both sides. If the Internet connection went down on site 1, clients would route through site 2, to the Web cluster, and then to the database in site 1 if the link between both sites is still up. With this scenario, due to the lack of physical link (serial) there is a more likely chance of split brain. If the WAN went down between both sites, the VIP would end up on both sites, where a variety of unpleasant scenarios could introduce desync. Another potential issue I see is difficulty scaling this infrastructure to a third data center in the future. The network layer is not a focus. The architecture is flexible at this stage. Again, my focus is a solution for maintaining data integrity as well as automatic failover with the MySQL databases. I would likely design the rest around this. Can you recommend a proven solution for MySQL HA between two physically diverse sites? Thank you for taking the time to read this. I look forward to reading your recommendations.

• How to use DNS/Hostnames or Other ways to resolve to a specific IP:Port

  - by tomaszs

  This is a Canonical Question about DNS/Hostnames resolution to IPs/Ports Example 1 I'm running a web server on port 80 and another on port 87. I would like to use DNS so that www.example.com goes to port 87. How can I accomplish this using DNS only? Example 2 I'm running a service on my server on a non-standard port. How can I get clients to connect to this non-standard port automatically? Can I use DNS? Is there some application specific support where DNS could indicate the IP and Port? Example 3 Do some application protocols specifically support hostname awareness, and allow special actions to be taken based on this information? Are there other questions on Server Fault that cover some of these? Commandeering: This question was originally asking about running IIS and Apache on the same server, but the same concepts can be applied to any server software receiving connections from clients. The Answers below describe the technical problems and solutions of using DNS and application protocol support to assign a port number for a client to connect.
