• IPSec tunnelling with ISA Server 2000...

  - by Izhido

  Believe it or not, our corporate network still uses ISA Server 2000 (in a Windows Server 2003 machine) to enable / control Internet access to / from it. I was asked recently to configure that ISA Server to create a site-to-site VPN for a new branch in a office about 25 km. away from it. The idea is basically to enable not only computers, but also Palm devices (WiFi-enabled, of course), to be able to see other computers in both sites. I was also told that a simple VPN-enabled wireless AP/router (in this case, a Cisco WRV210 unit) should be enough to establish communications with the main office. To be fair, the router looks easy to configure; it was confusing at first, but further understanding of how site-to-site VPNs work cleared all doubts about it. Now I need to make modifications to our ISA Server in order to recognize the newly installed & configured "remote" VPN site. Thing is, either my Googling skills are pathethically horrible, or there doesn't seem to be much (or any, at all) information about how to configure an ISA Server 2000 for this purpose. Lots of stuff on 2004, of course; also, I think I saw something for 2006. But nothing I could find about 2000. Reading about 2004, it seems that the only way I can do site-on-site with a Cisco router (read: a non-ISA-Server machine) is through something they call a "IPSec tunnel". Fair enough. However, I can't figure for the life of me how could I even start to find, leave alone configure, such a thing. Do you, people, happen to know how to do IPSec tunelling on a ISA Server 2000, so I can connect to a Cisco WRV210 VPN-enabled router, and build a site-to-site VPN for both networks? Or is this not possible at all? (Meaning I should change anything in this configuration to make it work...)

• IIS serving pages extremely slowly

  - by mos

  TL;DR: IIS 7 on WS2008R2 serves pages really slowly; everyone assumes it's because it's IIS and we should have gone with an Apache solution on Linux. I have no idea where to start debugging the problem. I work in a nearly all-MS shop with a bunch of fellow programmers who think Linux is the One True Way. Management recently added a Windows machine with IIS to serve Target Process (third-party agile system), but the site runs extremely slowly. Everyone, to a man, assumes it's because it's on IIS, and if only management would grow a brain and get some Linux servers in here, we could really start cleaning things up! ...Right. Everyone "knows" IIS isn't fit to serve .txt files. ...Well, as the only non-Microsoft hater in the bunch, I am apparently the only one who thinks maybe the Linux guy who hated being told to set up the IIS server may have screwed things up. I'd like to go fix it, but I don't have any clue as to where to start as I am not a sys admin. Help?

• Controller Error: Do I need to worry?

What is a ATAPI Error? Do I need to re-install Windows? I generally find the occurs when I try to backup my machine (using Windows Backup) or when using a program that uses Volume Shadow Copy. I have run "sfc", no problems. There are no Device Errors in Device Manager. I have also run "vssadmin list writers", no problems. Whats going on??? Would it be a good idea to re-install Windows 7?

• Is my OCZ SSD aligned correctly? (Linux)

  - by Barney Gumble

  I have an OCZ Agility 2 SSD with 40 GB of space. I use it as a system drive in Debian Linux (Squeeze) and in my opinion it's really fast. But I've read a lot on aligning partitions and file systems... And I'm not sure if I succeeded in aligning the partitions correctly. Maybe the SSD could be even faster?? ;-) I use ext4 and here is the output of fdisk -cul: Disk /dev/sda: 40.0 GB, 40018599936 bytes 255 heads, 63 sectors/track, 4865 cylinders, total 78161328 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: [...] Device Boot Start End Blocks Id System /dev/sda1 * 2048 73242623 36620288 83 Linux /dev/sda2 73244670 78159871 2457601 5 Extended /dev/sda5 73244672 78159871 2457600 82 Linux swap / Solaris My partitions were created just by the Debian Squeeze setup assistant. So I didn't care about the details of partitioning. But now I think maybe the installer didn't align it correctly? Actually, 2048 looks good to me (better than odd values like 63 or something like that) but I've no idea... ;-) Help plz! According to some "SSD Alignment Calculator" I found on the web, the OCZ SSDs have a NAND Erase Block Size of 512kB and their NAND Page Size is 4kB. 2048 is divisible by 4 and 512. So are the partitions aligned correctly?

• v2v of RHEL5 box - issues with retaining MAC address

  - by Alex Berry

  For the last week we have been troubleshooting a customer's Red Hat Virtual Machine running on ESXi. We've been using Veeam to try to create a replica off-site and have been having getting it to work on a decent schedule and recently we noticed that there were issues with orphaned snapshots while looking at the datastore. You can see several snapshots in the same folder and it's causing issues with replication and backup, so we decided the cleanest way was to v2v the machine to another datastore so that we had a clean single-vmdk setup to work with, this is where our trouble started. We first started off with a v2v using vmware converter and connecting to the powered on machine as we were having issues doing an offline v2v. This copied fine but when I tried to set a static MAC using this article http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=507 the new VM wouldn't take the address, it simply obtained a new MAC, received a dhcp lease and then would only boot up to a blank red screen, never the login screen. So the next step was to do an offline v2v, once we finally got it working. Same thing, followed the kb to the letter and still it wouldn't take the MAC. I then tried it again and upon completion I compared both old and new VMX file, copying every identifier and variable possible, then unregistered both VMs, uploaded the new VMX file and booted, only to see the same results. Finally I did the same as above but I copied the disk using DD to a second attached vmdk and then attached this to the new VM, and still no luck. After downloading the modified VMX file after the first boot and comparing it to the original I created I found that the bios uuid had changed from the one I typed in manually, so I'm assuming this may be the snagging point, but I have no idea. I've never had this issue before on a P2V and I'm just wondering if someone could shed some light on this, maybe it's to do with RHEL licencing?

• OpenVZ: Choosing right MySQL-Server depending on host

  - by Scheintod

  What I have: Two servers running Wheezy/OpenVZ with One MySQL container on each host master/master replicated (mysql1/mysql2) Replicated DNS on each host (dns1/dns2) different web-containers on each host but regulary backuped to the other. What I want: Each container should use the "local" MySQL-Server (the one which runs on the same hardware-node). I'd like to be able to move the web-containers between the to hosts. Each container should choose the MySQL-Server (semi) automatically. This scheme should continue working if one host is down. What I tried: Currently I'm keeping track on which container should run on which host by DNS entries which are queries by scripts e.g. for questions like: "Which container should be backuped on/to which host." For choosing the right MySQL server I have one extra entry like "mysql.container_abc" which resolves to either mysql1/mysql2. So in the applications in the container I can use "mysql.container_abc" for e.g. mysql_connect and if I want to move the container around I just need to change the dns. Now I notices one problem with this approach: Every mysql_connect generates one DNS query because the dns is not cached and this slows the request down unnecessarily. What I would like better: Some way of passing the information on which host we are running to the container and using it directly instead of using DNS. E.g. some way of setting a custom /etc/hosts entry in the container. Or any other great idea. Doesn't have to include DNS but shouldn't require to much special "magic" inside the container.

• Unable to get ejabberd prebind to work

  - by cdecker

  I'm trying to get the prebind of BOSH sessions to work. I want to be able to authenticate a user in my CMS and then log him in when he accesses the chat, for this I found https://github.com/smokeclouds/http_prebind, it all works find and I was able to compile it with the following steps: rake configure sed -i 's/AUTH_USER/a_user/g' src/http_prebind.erl sed -i 's/AUTH_PASSWORD/a_password/g' src/http_prebind.erl sed -i 's/EJABBERD_DOMAIN/jabber.my.tld/g' src/http_prebind.erl rake build rake install And then adding the http request bindings to the configuration: {5280, ejabberd_http, [ {request_handlers, [ {["http-prebind"], http_prebind} ]}, %%captcha, http_bind, http_poll, http_prebind, web_admin ]} ]}. As far as I understand it I should now be able to simply request a new session like this: curl -u a_user:a_password http://jabber.my.tld:5280/http-prebind/some_user But no matter what I always get Unauthorized as response. Any idea about this one? PS: I also tried Mod-Http-Pre-Bind, but as it does not require a password I would prefer to use http_prebind. PPS: Does the user with username AUTH_USER and password AUTH_PASSWORD actually have to exist? I'm currently using an admin account.

• Setting up MySQL Linux slave with a Windows master

  - by philwilks

  I'm running a MySQL 5.0 database server on Windows Server 2008. The total size of the database is about 1Gb. I make daily backups, but I'd like to step up to having a slave server for extra protection. My thinking was that I wouldn't need the expense of a Windows machine to do this, and a Linux "cloud server" from RackSpace would do the job well for quite a low cost. However I have little experience with Linux, so I have a few questions... Does this sound like a good idea? Is there anything wrong with linking Windows and Linux MySQL servers? Does Linux have the equivalent of Remote Desktop Connection? If so can I use this from a Windows machine? Would a particular Linux distro be well suited to this task? RackSpace offer ArchLinux, CentOS, Debian, Fedora and Ubuntu. My immediate thinking is to go with Ubuntu as I've heard it's more friendly for people coming from a Windows background. Any comments you have would be very appreciated! Phil

• Bouncing between a 502 and 503 error

  - by Dave

  This has become an increasingly frustrating ordeal. I'm mostly a web developer, so forgive me if I am using improper terminology here. I have a client that had purchased a domain at JustHost. We built him a website and have it on our own server space. Now, I'm mostly used to dealing with godaddy and it is simple enough to manage dns records and point the A record to our server IP, where Apache on our end deals with the domains via name-based virtual hosts. But for some reason, in setting this up with JustHost, when attempting to go to the domain name, I either get a 502 or 503 error or "webpage does not exist". Now, I know that the basic functionality of the webpage must be working because I can access the the index etc straight through my servers www data (IE [server-ip]/website_folder). I was on the phone with technical support for over three hours yesterday with justhost and the best I could get was "That's really weird..." I've checked my logs and there doesn't seem to be anything coming through to my end. Does anybody have an idea of whats going on here? I would love for it to be a problem on my end, because justhost doesn't seem capable of helping further. Any help is greatly appreciated, thanks. I forgot to mention that we have several other sites up and running and completely accessible.

• apache: can't renew ssl certificate

  - by Caballero

  I have Godaddy SSL certificate for one website on my dedicated server running Centos 5.3 / Apache 2.2.3. I have renewed certificate on Godaddy recently, however now it's showing as expired on my website. I've re-keyed certificate since and reuploaded domain.key, domain.crt and bundle.crt (example file names) files to the server, restarted apache, but the sertificate still shows as expired. I'm running out of clues. I've tried replacing content of .crt files with jiberish and restart apache - it's still showing that certificate is expired, even though it shouldn't be picked up at all. I eventually rebooted dedicated server, still no luck. I'm using free SSL check tool http://www.digicert.com/help/ which clearly shows all the green checks except one - certificate is expired. Has someone any idea what might be causing this? Could there be some kind of caching going on here? UPDATE: after running openssl x509 -in domain.crt -noout -enddate I'm getting this output: notAfter=Jun 2 08:16:51 2013 GMT So I asume this means I have the right certificate on the server and yet the old expired one shows on the web...

• Default /server-status location not inheriting in Apache

  - by rmalayter

  I'm having a problem getting /server-status to work Apache 2.2.14 on Ubuntu Server 10.04.1. The default symlinks for status.load and status.conf are present in /etc/apache2/mods-enabled. The status.conf does include the location /server-status and appropriate allow/deny directives. However, the only vhost I have in sites-enabled looks like this. The idea is to proxy anything with a Tomcat URL to a cluster of tomcats, and anything else to an IIS box. However, this seems to result in requests to /server-status being sent to IIS. Copying the /server-status in explicitly to the Vhost configuration doesn't seem to help, no matter what order I use. Is it possible to include /server-status do this within a vhost configuration that has a "default" proxy rule?: <VirtualHost *:80> ServerAdmin webmaster@localhost DocumentRoot /var/www Header add Set-Cookie "ROUTEID=.%{BALANCER_WORKER_ROUTE}e; path=/" env=BALANCER_ROUTE_CHANGED <Proxy balancer://tomcatCluster> BalancerMember ajp://qa-app1:8009 route=1 BalancerMember ajp://qa-app2:8009 route=2 ProxySet stickysession=ROUTEID </Proxy> <ProxyMatch "^/(mytomcatappA|mytomcatappB)/(.*)" > ProxyPassMatch balancer://tomcatCluster/$1/$2 </ProxyMatch> #proxy anything that's not a tomcat URL to IIS on port 80 <Proxy /> ProxyPass http://qa-web1/ </Proxy>

• Route specific network traffic through vpn in virtualbox guest

  - by Sander

  I am running OSX with a windows server 2008 guest in Virtualbox. My goal is to route some of the network traffic in the host through the server guest. This is because the win2008 server has a VPN connection to my workplace using a Smartcard solution which can not operate on OSX. My current set-up is like this: OSX (Host): connected to the internet via en01 Win2008 (Guest): connected to the internet using NAT (lan1 in guest) has a SSTP VPN connection to my workplace is connected to the guest using an Host Only Adapter vboxnet0 (LAN2 in guest) The important part is about the host (OSX). Primarily I want all network traffic to just go through en01. However, all traffic which can only be accessed through the VPN must go through the guest and through the VPN. I have one specific FQDN which can only be accessed through the VPN (say corp.mycompany.com). I do not know much about networking. I thought I would be able to get it to work by bridging together LAN2 and LAN1 but this didn't seem to work this: http://archives.aidanfindlater.com/blog/2010/02/03/use-vpn-for-specific-sites-on-mac-os-x/ using a loopback adapter on WinXP (when I did not have win2008 yet, but this doesn't work because I can't create a PPTP connection) And I've also read about Routing and Remote Access but I have no idea on how to use this. Can someone help me in the right direction?

• Problem in accessing Windows shared folder on Ubuntu using terminal

  - by vikramtheone

  Hi Guys, Description I have 2 systems with me, one running on Windows(Host) and one on Ubuntu, both on a LAN. On the Windows(Host) I develop software intended for the Linux system and because the Linux system has little external memory, my idea to overcome this is by making the project folder on the Host side a Shared Folder with full access and access it on Ubuntu over the network. To achieve this, I have installed Samba on Ubuntu, when I go to Places -> Network I can see the shared project folder and I simply mount it. A link appears on the desktop. Next, using Nautilus I open the link and I can access the contents of the shared folder. Problem Even though I mount the shared project folder, I don't see it appearing in the /media or the /mnt folder, as a result of this I don't know what path to use to access this folder, from the terminal. For example: When, I mounted my USB stick, as expected, a link for the device appears on the Desktop and I also see a folder in the media folder. So, similarly, a mounted shared folder should have appeared on the /mnt folder, too. Can anyone suggest what I should do now? There are many posts around, but no solid solution for this problem. Help!!! :) Vikram

• Requests per second slower when using nginx for load balancing

  - by Ed Eliot

  I've set up nginx as a load balancer that reverse proxies requests to 2 Apache servers. I've benchmarked the setup with ab and am getting approx 35 requests per second with requests distributed between the 2 backend servers (not using ip_hash). What is confusing me is that if I query either of the backend servers directly via ab I get around 50 requests per second. I've experimented with a number of different values in ab the most common being 1000 requests with 100 concurrent connections. Any idea why traffic distributed across 2 servers would result in fewer requests per second than hitting either directly? Additional info: I've experimented with worker_processes values of between 1 and 8, worker_connections between 1024 and 8092 and have also tried keepalive 0 and 65. My main conf currently looks like this: user www-data; worker_processes 1; error_log /var/log/nginx/error.log; pid /var/run/nginx.pid; worker_rlimit_nofile 8192; events { worker_connections 2048; use epoll; } http { include /etc/nginx/mime.types; sendfile on; keepalive_timeout 0; tcp_nodelay on; gzip on; gzip_disable "MSIE [1-6]\.(?!.*SV1)"; include /etc/nginx/conf.d/*.conf; include /etc/nginx/sites-enabled/*; } I've got one virtual host (in sites available) that redirects everything under / to 2 backends across a local network.

• Multiple *NIX Accounts with Identical UID

  - by Tim

  I am curious whether there is a standard expected behavior and whether it is considered bad practice when creating more than one account on Linux/Unix that have the same UID. I've done some testing on RHEL5 with this and it behaved as I expected, but I don't know if I'm tempting fate using this trick. As an example, let's say I have two accounts with the same IDs: a1:$1$4zIl1:5000:5000::/home/a1:/bin/bash a2:$1$bmh92:5000:5000::/home/a2:/bin/bash What this means is: I can log in to each account using its own password. Files I create will have the same UID. Tools such as "ls -l" will list the UID as the first entry in the file (a1 in this case). I avoid any permissions or ownership problems between the two accounts because they are really the same user. I get login auditing for each account, so I have better granularity into tracking what is happening on the system. So my questions are: Is this ability designed or is it just the way it happens to work? Is this going to be consistent across *nix variants? Is this accepted practice? Are there unintended consequences to this practice? Note, the idea here is to use this for system accounts and not normal user accounts.

• Remote Desktop Connection issues

  - by stead1984

  I have a server at a remote site, the sites are connected to each other a site-to-site VPN connection using Cisco ASA 5510 firewalls. One end is managed by me, the other managed by the remote location's IT, between the 2 of us is another party who manage and route the connections. Remote desktop has been working fine with no problems then recently I noticed it was working for ONE server over the VPN which it previously had done. All the routes seem fine and I can still ping the remote server and even download files from an FTP site on the remote server.... so the VPN seems fine. Remote Desktop works fine to the remote server within the remote location but not over the VPN. I don't understand why it's stopped working, I originally thought it was a rule in place by the other party but they stress it's not them. The only thing that has changed on the server initiating the RDP connection is that it now runs file services sharing a folder. The source server (remote location) may or may not have had updates applied. Any idea's?

• iptables to block VPN-traffic if not through tun0

  - by dacrow

  I have a dedicated Webserver running Debian 6 and some Apache, Tomcat, Asterisk and Mail-stuff. Now we needed to add VPN support for a special program. We installed OpenVPN and registered with a VPN provider. The connection works well and we have a virtual tun0 interface for tunneling. To archive the goal for only tunneling a single program through VPN, we start the program with sudo -u username -g groupname command and added a iptables rule to mark all traffic coming from groupname iptables -t mangle -A OUTPUT -m owner --gid-owner groupname -j MARK --set-mark 42 Afterwards we tell iptables to to some SNAT and tell ip route to use special routing table for marked traffic packets. Problem: if the VPN failes, there is a chance that the special to-be-tunneled program communicates over the normal eth0 interface. Desired solution: All marked traffic should not be allowed to go directly through eth0, it has to go through tun0 first. I tried the following commands which didn't work: iptables -A OUTPUT -m owner --gid-owner groupname ! -o tun0 -j REJECT iptables -A OUTPUT -m owner --gid-owner groupname -o eth0 -j REJECT It might be the problem, that the above iptable-rules didn't work due to the fact, that the packets are first marked, then put into tun0 and then transmitted by eth0 while they are still marked.. I don't know how to de-mark them after in tun0 or to tell iptables, that all marked packet may pass eth0, if they where in tun0 before or if they going to the gateway of my VPN provider.

• How do I use key combinations on an axis on a joystick in xorg?

  - by valadil

  I'm using xserver-xorg-input-joystick on Debian Stable so I can use a joystick in place of the mouse. I have mouse movement working correctly, but got stuck trying to add functions for some other keys. These work: #Left stick #Pointer Option "MapAxis1" "mode=relative axis=1.5x" Option "MapAxis2" "mode=relative axis=1.5y" #Right stick #Arrow keys Option "MapAxis4" "mode=relative keylow=Left keyhigh=Right" Option "MapAxis5" "mode=relative keylow=Up keyhigh=Down" But when I try to make key combos (so I can navigate windows and screens in xmonad) I have no luck. #dpad #xmonad focus #up/down toggle window. l/r choose screen. Option "MapAxis8" "mode=relative keylow=Super_L,k keyhigh=Super_L,j" Option "MapAxis7" "mode=relative keylow=Super_L,w keyhigh=Super_L,e" I've also tried Super_R, plain old Super, Meta, and mod4mask, and anything else I can think of. These buttons print the letter, but don't appear to hold down the modifying key. The exception to that is shift. If I specify Shift_L or Shift_R, I get a capital letter. xev indicates that modifier keys are being pressed. If I lower Axis8, I get press Super_L, press k, release k, release Super_L. That looks like it should be working. Maybe this is an xmonad problem and not a joystick driver one? I'm also having trouble with getting an axis to use other XF86 keys: # triggers # song selection Option "MapAxis3" "mode=relative keylow=none keyhigh=XF86AudioForward" Option "MapAxis6" "mode=relative keylow=none keyhigh=XF86AudioBack" That does nothing. Any idea why? If it turns out that this isn't something I can do on an axis, but would work with a button, is there a way to treat my joysticks as buttons? Also, if anyone has suggestions for the other 5 buttons I'll have left after mouse buttons are bound, I'm listening.

• OS X can connect to Windows machine, but can't access shared folders

  - by Bonnie

  I can create new folders on my Windows XP machine, set them to "shared". On my Mac, I pick Finder → Go → Connect to Server → smb://192.168.1.4 → Connect → Name / Password. It even shows me all the names of the newly created shared-folders on my PC, but when I try to actually connect to any of them I get connection failed, there was an error connecting Any idea on what would cause that? The fact that it successfully gets so far—to actually showing me my PC share-names—must mean I have 99% of this working correctly, i.e. the physical connection, the IP address, the user name, the password, etc. Still, I can't seem to access the folders themselves. I've tried this with my Windows XP firewall on/off, and Norton AntiVirus on/off. Same problem. Everything did work fine, 4 months ago. Were there any odd OS X or Windows updates released recently? I always apply them all. smbclient on the Mac does correctly find the XP machine, my XP user name, and accepts my XP password. I get the following from that smbclient command: Doing spnego session setup (blob length=16) server didn't supply a full spnego negprot Got challenge flags: ... Got NTLMSSP flags: ... Got NTLMSP flags: ... Domain=[XPMACHINE] OS=[Windows 5.1] Server=[Windows 2000 LAN Manager] tree connect failed: NT_STATUS_INSUFF_SERVER_RESOURCES I'm not sure why a standard XP box can't "supply a full spnego negprot". Whatever that means. Using XP's RegEdit to change my IRPStackSize from 11... to 13, 15, 20, 22... still gives that "NT_STATUS_INSUFF_SERVER_RESOURCES" error on the Mac.

• Migrate Windows Server 2008 to a new hard disk

  - by MainMa

  Hi, I have a machine with Windows Server 2008. I want to change the hard disk drive, but keep everything else. I don't have a cd/dvd drive and don't want to buy it. My first idea was to make a byte-to-byte copy of the disk with Paragon Advanced Recovery. The problem is that when I try to boot from a new hard disk, it says that there were hardware changes and that Windows must be repaired, inviting me to insert the installation disk and follow repair instructions. I searched and found that 1:1 copy is not a correct way to do things. The correct one is to restore Windows to a new hard disk from a full system backup. But to restore, I need to have a dvd drive. I tried to make a copy of the Windows Server 2008 .iso on an USB flash drive, but the drive is not bootable (while the same procedure applied to Paragon Advanced Recovery ISO produces a bootable recovery USB flash drive). Now what else can I do (except buying a dvd drive)? Is there a way either to make Windows work without doing recovery or recover Windows 2008 without using a cd drive?

• Issues using gmail with google apps and external domain

  - by Jonathan Kelly

  I have recently tried to use gmail through google apps as my main email client, but I'm experiencing a few different problems. I am managing the domain (conjunktiondesign.co.uk) through 123reg.co.uk but it is hosted through fasthosts.co.uk. I transfered the domain to 123reg as fasthosts did not allow me to change the MX records myself. I followed the setup instructions step by step on google apps and changed the MX records as they told me to. My email was now working perfectly but my website was down and I was getting the following error: The dnsserver returned: No DNS records I have a friend that is using the same system as me (ie. Externally hosted domain and google apps mail) and I changed my 123reg details to the same that he had (as his was working perfectly - both email and website). I changed my name servers to point to fasthosts, rather than 123reg and I added an A record called '@' pointing to fasthosts IP address. I also created another A record called 'www' pointing to fasthosts IP address. After I did this, my website worked almost immediately but I have only realised that since changing it my email is now down. I have not received anything since Saturday. I am a web designer and would consider myself fairly tech savvy, but I have no idea about A records, CNAME's and all the things I have been messing about with! What I ultimately need is someone to help me get my email and website working at the same time, rather than one being down when the other is OK. I seem only able to get one or the other working. I have now changed the name servers back to 123reg in an attempt to get my email back as it is more important than my website at this stage. Any help is much appreciated. Thanks.

• How do I run multiple MVC apps within a subdomain on IIS7?

  - by Matthew Patrick Cashatt

  Hello and thanks for looking. Background I am currently wrapping up a development contract and the client would like for me to push a build of the application to their IIS 7-based server in which they would like to run multiple MVC apps. One of the issues I have off of the bat is that this server is already a subdomain on their larger network. So, if I enter SERVERNAME in my browser, it automatically directs to SERVERNAME.COMPANYNAME.COM. Now, this is just fine if I place my application in the default website/root. In this scenario, clicking a link that requests admin.html directs to `SERVERNAME.COMPANYNAME.COM/admin.html' as usual. BUT they want me to place the app in a subdomain on this server so that they can also run other apps on the same server. So I assume that I need MYAPP.SERVERNAME.COMPANYNAME.COM but I have no idea how to do that. Complicating matters is that my app and the future ones they wish to install are all MVC based which intercepts and re-writes URLs. I assume that this takes care of itself if I can just successfully get my app into a subdomain to begin with. What I have tried Creating a new site on the server in it's own app pool Setting the binding for that site to MYAPP.SERVERNAME.COMPANYNAME.COM Setting the binding for that site to MYAPP Setting the binding for that site to MYAPP.SERVERNAME Setting the binding for that site to MYAPP.SERVERNAME.COM Setting the binding for that site to MYAPP.COMPANYNAME.COM Nothing is working. Am I missing something simple here? Thanks, Matt
