• CentOS Client - Unable to Establish iSCSI connection with multiple interfaces on the initiator

  - by slashdot

  So after upgrading to CentOS 6.2, I am seemingly no longer able to login into my iSCSI targets. I have multiple interfaces on different subnets on the system, and I first thought that it had to do with the fact that I may not be binding correct interfaces, which seems to be the case when looking at netstat, as this is clearly wrong: [root]? netstat -na|grep .90 tcp 0 1 10.10.100.60:42354 10.10.8.90:3260 SYN_SENT tcp 0 1 10.10.100.60:40777 10.10.9.90:3260 SYN_SENT I then went ahead and disabled all but one interface, and so as a result netstat appears to be correct, but the issue with login remains. I am positive that the target never sees a packet, because I see nothing by SYN_SENT. I know the problem is on my client, because the target is servicing multiple systems, none of which are CentOS 6.2. At this point I am pretty confident that some things changed between CentOS 6.0/6.1 and 6.2. So, if anyone have any thoughts, or ran into this, I would very much like to hear your thoughts.

I went a few weeks back and grabbed a snapshot of this system from before upgrading to 6.2. I spun up a new system from the snapshot, and reconfigured interface info and host keys, as well as iSCSI initiator and iscsi interface info to match new MACs. Changed nothing else. Then, I attempted to connect to my targets, and no issues at all. I cannot say that this was unexpected. I then went ahead and compared sysctl settings from both systems and there were differences after the upgrade, but nothing seemingly relevant to iSCSI or IP that could contribute to this. I also noticed that by default now two sessions per connection were enabled after the upgrade, but I changed it back to 1 session in /etc/iscsi/iscsid.conf. On the problematic system we can see that source interface is seemingly wrong, but even when I disable the 10.10.100 interface, problems persist. So, while this may be relevant, I could not validate it for certain. Needless to say, further research is necessary. Something is clearly different between releases. Working system is on 6.1, and non-working is 6.2. ::Working System:: tcp 0 0 10.10.8.210:39566 10.10.8.90:3260 ESTABLISHED tcp 0 0 10.10.9.210:46518 10.10.9.90:3260 ESTABLISHED [root]? ip route show 10.10.8.0/24 dev eth2.6 proto kernel scope link src 10.10.8.210 10.10.9.0/24 dev eth3.7 proto kernel scope link src 10.10.9.210 10.10.100.0/22 dev eth0 proto kernel scope link src 10.10.100.210 169.254.0.0/16 dev eth0 scope link metric 1002 169.254.0.0/16 dev eth2.6 scope link metric 1006 169.254.0.0/16 dev eth3.7 scope link metric 1007 default via 10.10.100.1 dev eth0 ::Non-working System:: tcp 0 1 10.10.100.60:44737 10.10.9.90:3260 SYN_SENT tcp 0 1 10.10.100.60:55479 10.10.8.90:3260 SYN_SENT [root]? ip route show 10.10.8.0/24 dev eth2.6 proto kernel scope link src 10.10.8.60 10.10.9.0/24 dev eth3.7 proto kernel scope link src 10.10.9.60 10.10.100.0/22 dev eth0 proto kernel scope link src 10.10.100.60 169.254.0.0/16 dev eth0 scope link metric 1002 169.254.0.0/16 dev eth2.6 scope link metric 1006 169.254.0.0/16 dev eth3.7 scope link metric 1007 default via 10.10.100.1 dev eth0 And the result is still same: [root]? iscsiadm: Could not login to [iface: sw-iscsi-0, target: iqn.2011-12.dom.homer:01:lab-centos-servers-00001, portal: 10.10.8.90,3260]. iscsiadm: initiator reported error (8 - connection timed out) iscsiadm: Could not login to [iface: sw-iscsi-1, target: iqn.2011-12.dom.homer:02:lab-centos-servers-00001, portal: 10.10.9.90,3260]. iscsiadm: initiator reported error (8 - connection timed out) iscsiadm: Could not log into all portals Update 01/08/2012: I believe I have been able to figure out the answer to my issue. It is quite obscure and I doubt this will happen to anyone else any time soon. It turns out that setting iface.iscsi_ifacename and iface.hwaddress in the interfaces configuration file is not legal. When one manually adds an iscsi target, such as below, all settings from the interface config file are copied into the node config file, that gets created by the below command. Result is parameters iface.iscsi_ifacename and iface.hwaddress together in the same config file. These parameters are seemingly mutually exclusive, which does not exactly make sense, or there is perhaps an oversight in the codepath. Perhaps I will investigate further. # iscsiadm -m node --op new -T iqn.2011-12.dom.homer:01:lab-centos-servers-00001 -p 10.10.8.90,3260,2 -I sw-iscsi-0 # iscsiadm -m node --op new -T iqn.2011-12.dom.homer:02:lab-centos-servers-00001 -p 10.10.9.90,3260,2 -I sw-iscsi-1 Notice, below I commented out iface.hwaddress and iface.ipaddress, after which I re-added targets, with same command as above. All works just fine. [root]? cat * # BEGIN RECORD 2.0-872.33.el6 iface.iscsi_ifacename = sw-iscsi-0 iface.net_ifacename = eth2.6 #iface.hwaddress = XX:XX:XX:XX:XX:XX #iface.ipaddress = 10.10.8.60 iface.transport_name = tcp iface.vlan_id = 6 iface.vlan_priority = 0 iface.iface_num = 0 iface.mtu = 0 iface.port = 0 # END RECORD # BEGIN RECORD 2.0-872.33.el6 iface.iscsi_ifacename = sw-iscsi-1 iface.net_ifacename = eth3.7 #iface.hwaddress = XX:XX:XX:XX:XX:XX #iface.ipaddress = 10.10.9.60 iface.transport_name = tcp iface.vlan_id = 7 iface.vlan_priority = 0 iface.iface_num = 0 iface.mtu = 0 iface.port = 0 # END RECORD Again, chances of this happening to someone else are slim to none, so likely waste of time typing this up. But, if someone does encounter this issue, I hope this post will help.

• Our winners- and some BBQ for everyone

  - by Steve Tunstall

  Congrats to our two winners for the first two comments on my last entry. Steve from Australia and John Lemon. Steve won since he was the first person over the International Date Line to see the post I made so late after a workday on Friday. So not only does he get to live in a country with the 2nd most beautiful women in the world, but now he gets some cool Oracle Swag, too. (Yes, I live on the beach in southern California, so you can guess where 1st place is for that other contest…Now if Steve happens to live in Manly, we may actually have a tie going…) OK, ok, for everyone else, you can be winners, too. How you ask? I will make you the envy of every guy and gal in your neighborhood or campsite. What follows is the way to smoke the best ribs you or anyone you know have ever tasted. Follow my instructions and give it a try. People at your party/cookout/campsite will tell you that they’re the best ribs they’ve ever had, and I will let you take all the credit. Yes, I fully realize this post is going to be longer than any post I’ve done yet. But let’s get serious here. Smoking meat is much more important, agreed? J In all honesty, this is a repeat of another blog I did, so I’m just copying and pasting. Step 1. Get some ribs. I actually really like Costco’s pack. They have both St. Louis and Baby Back. (They are the same ribs, but cut in half down the sides. St. Louis style is the ‘front’ of the ribs closest to the stomach, and ‘Baby back’ is the part of the ribs where is connects to the backbone). I like them both, so here you see I got one pack of each. About 4 racks to a pack. So these two packs for $25 each will feed about 16-20 of my guests. So around 3 bucks a person is a pretty good deal for the best ribs you’ll ever have. Step 2. Prep the ribs the night before you’re going to smoke. You need to trim them to fit your smoker racks, and also take off the membrane and add your rub. Then cover and set in fridge overnight. Here’s how to take off the membrane, which will not break down with heat and smoke like the rest of the meat, so must be removed. Use a butter knife to work in a ways between the membrane and the white bone. Just enough to make room for your finger. Try really hard not to poke through the membrane, you want to keep it whole. See how my gloved fingers can now start to lift up and pull off the membrane? This is what you are trying to do. It’s awesome when the whole thing can come off at once. This one is going great, maybe the best one I’ve ever done. Sometime, it falls apart and doesn't come off in one nice piece. I hate when that happens. Now, add your rub and pat it down once into the meat with your other hand. My rub is not secret. I got it from my mentor, a BBQ competitive chef who is currently ranked #1 in California and #3 in the nation on the BBQ circuit. He does full-day classes in southern California if anyone is interested in taking his class. Go to www.slapyodaddybbq.com to check him out. I tweaked his run recipe a tad and made my own. It’s one part Lawry’s, one part sugar, one part Montreal Steak Seasoning, one part garlic powder, one-half part red chili powder, one-half part paprika, and then 1/20th part cayenne. You can adjust that last ingredient, or leave it out. Real cheap stuff you can get at Costco. This lets you make enough rub to last about a year or two. Don’t make it all at once, make a shaker’s worth and use it up before you make more. Place it all in a bowl, mix well, and then add to a shaker like you see here. You can get a shaker with medium sized holes on it at any restaurant supply store or Smart & Final. The kind you see at pizza places for their red pepper flakes works best. Now cover and place in fridge overnight. Step 3. The next day. Ok, I’m ready to go. Get your stuff together. You will need your smoker, some good foil, a can of peach nectar, a bottle of Agave syrup, and a package of brown sugar. You will need this stuff later. I also use a clean spray bottle, and apple juice. Step 4. Make your fire, or turn on your electric smoker. In this example I’m using my portable charcoal smoker. I got this for only $40. I then modified it to be useful. Once modified, these guys actually work very well. Trust me, your food DOES NOT KNOW how expensive your smoker is. Someone who tells you that you need to spend a bunch of money on a smoker is an idiot. I also have an electric smoker that stays in my backyard. It’s cleaner and larger so I can smoke more food. But this little $40 one works great for going camping. Here is what my fire-bowl looks like. I leave a space in the middle open, and place cold charcoal and wood chucks in a circle going outwards. This makes it so when I dump the hot coals down the middle, they will slowly burn outwards, hitting different wood chucks at different times, allowing me to go 4-5 hours without having to even touch my fire. For ribs, I use apple and pecan wood. Pecan works for anything. Apple or any fruit wood is excellent for pork. So now I make my hot charcoal with a chimney only about half-full. I found a great use for that side-burner on my grill that I never use. It makes a fantastic chimney starter. You never use fluids of any kind, nor ever use that stupid charcoal that has lighter fluid built into it. Never, ever, ever. Step 5. Smoke. Add your ribs in the racks and stack them up in your smoker. I have a digital thermometer on a probe that I use to keep track of the temp in the smoker. I just lay the probe on the top rack and shut the lid. This cheap guy is a little harder to maintain the right temperature of around 225 F, so I do have to keep my eye on it more than my electric one or a more expensive charcoal one with the cool gadgets that regulate your temp for you. Every hour, spray apple juice all over your ribs using that spray bottle. After about 3 hours, you should have a very good crust (called the Bark) on your ribs. Once you have the Bark where you want it, carefully remove your ribs and place them in a tray. We are now ready for a very important part to make the flavor. Get a large piece of foil and place one rib section on it. Splash some of the peach nectar on it, and then a drizzle of the Agave syrup. Then, use your gloved hand to pack on some brown sugar. Do this on BOTH sides, and then completely wrap it up TIGHT in the foil. Do this for each rib section, and then place all the wrapped sections back into the smoker for another 4 to 6 hours. This is where the meat will get tender and flavorful. The first three hours is only to make the smoke bark. You don’t need smoke anymore, since the ribs are wrapped, you only need to keep the heat around 225 for the next 4-6 hours. Obviously you don’t spray anymore. Just time and slow heat. Be patient. It’s actually really hard to overdo it. You can let them go longer, and all that will happen is they will get even MORE tender!!! If you take them out too soon, they will be tough. How do you know? Take out one package (use long tongs) and open it up. If you grab a bone with your tongs and it just falls apart and breaks away from the rest of the meat, you are done!!! Enjoy!!! Step 6. Eat. It pulls apart like this when it’s done. By the way, smoking tri-tip is way easier. Just rub it with the same rub, and put in your smoker for about 2.5 hours at 250 F. That’s it. Low-maintenance. It comes out like this, with a fantastic smoke ring and amazing flavor. Thanks, and I will put up another good tip, about the ZFSSA, around the end of November. Steve

• Django's self.client.login(...) does not work in unit tests

  - by thebossman

  I have created users for my unit tests in two ways: 1) Create a fixture for "auth.user" that looks roughly like this: { "pk": 1, "model": "auth.user", "fields": { "username": "homer", "is_active": 1, "password": "sha1$72cd3$4935449e2cd7efb8b3723fb9958fe3bb100a30f2", ... } } I've left out the seemingly unimportant parts. 2) Use 'create_user' in the setUp function (although I'd rather keep everything in my fixtures class): def setUp(self): User.objects.create_user('homer', '[email protected]', 'simpson') Note that the password is simpson in both cases. I've verified that this info is correctly being loaded into the test database time and time again. I can grab the User object using User.objects.get. I can verify the password is correct using 'check_password.' The user is active. Yet, invariably, self.client.login(username='homer', password='simpson') FAILS. I'm baffled as to why. I think I've read every single Internet discussion pertaining to this. Can anybody help? The login code in my unit test looks like this: login = self.client.login(username='homer', password='simpson') self.assertTrue(login) Thanks.

• Advanced (?) Excel sorting

  - by Preston Grayskull

  First of all, I'd like to admit that I don't really know anything about Excel, but I have tried to look up a solution to this in Excel books and Googling. Here's what I'm trying to do: I have a really long spreadsheet There are 7 columns total, but only two columns that I'm most interested in. Here's an example CSV that is much more simple than my actual dataset, but the search/sort is analogous: John, Apple Dave, Apple Dave, Orange Steve, Apple Steve, Orange Steve, Kiwi Bob, Apple Bob, Banana I'm interested in extracting the entire rows (all of the columns) that meet the following criteria: ["Apple"] OR ["Apple" and "Orange"] NOT ["Apple" and "Orange" and Anything Else] NOT ["Apple" and Anything that isn't Orange] So with the above CSV, I would get the entire rows for John and Dave, but not Steve and not Bob. I started doing this manually, and will likely finish by the time this question has an answer, but I would like to know this for future reference. Thanks!

• Is there a language where collections can be used as objects without altering the behavior?

  - by Dokkat

  Is there a language where collections can be used as objects without altering the behavior? As an example, first, imagine those functions work: function capitalize(str) //suppose this *modifies* a string object capitalizing it function greet(person): print("Hello, " + person) capitalize("pedro") >> "Pedro" greet("Pedro") >> "Hello, Pedro" Now, suppose we define a standard collection with some strings: people = ["ed","steve","john"] Then, this will call toUpper() on each object on that list people.toUpper() >> ["Ed","Steve","John"] And this will call greet once for EACH people on the list, instead of sending the list as argument greet(people) >> "Hello, Ed" >> "Hello, Steve" >> "Hello, John"

• VBUG Spring Conference, 28th and 29th March in Reading

  Looking for a job related to Microsoft (Internet Information Server)? Or do you have a job opening which requires IIS experience.  Look no further, subscribe to the discussion forum today at http://www.iisjobs.com and be notified as soon as a job is posted or someone responds. Why start IISJobs.com?  I'm not looking to replace Monster, Careers.com.  I've seen in various places where jobs involving Microsoft IIS (Internet Information Server) have been posted.   I thought it would be a good idea to centralize under a easy to remember domain name. :)   My goal is to help the IIS community.

• Contract-Popup at Login

  - by Steve

  I want to give my notebook to guests of my little Hotel as an extra service. I love the Ubuntu guest-account and I think that this is the best possible way to help my guests get free internet-access. I found out how to "design" their user-accounts with /etc/skel, but unfortunately I have no clue, how to show them a small introduction to the system and a kind of user-agreement "contract" when they login. I read of xmessage, but this is too minimalistic. I'd like to implement some pictures. Does anyone have any idea of how to make this possible? Would it be possible that the user is logged out automatically if he rejects the user-agreement? Thank you so much in advance, Steve.

• [Android] Launching activity from widget

  - by Steve H

  Hi, I'm trying to do something which really ought to be quite easy, but it's driving me crazy. I'm trying to launch an activity when a home screen widget is pressed, such as a configuration activity for the widget. I think I've followed word for word the tutorial on the Android Developers website, and even a few unofficial tutorials as well, but I must be missing something important as it doesn't work. Here is the code: public class VolumeChangerWidget extends AppWidgetProvider { public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds){ final int N = appWidgetIds.length; for (int i=0; i < N; i++) { int appWidgetId = appWidgetIds[i]; Log.d("Steve", "Running for appWidgetId " + appWidgetId); Toast.makeText(context, "Hello from onUpdate", Toast.LENGTH_SHORT); Log.d("Steve", "After the toast line"); Intent intent = new Intent(context, WidgetTest.class); PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, 0); RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.widget); views.setOnClickPendingIntent(R.id.button, pendingIntent); appWidgetManager.updateAppWidget(appWidgetId, views); } } } When adding the widget to the homescreen, Logcat shows the two debugging lines, though not the Toast. (Any ideas why not?) However, more vexing is that when I then click on the button with the PendingIntent associated with it, nothing happens at all. I know the "WidgetTest" activity can run because if I set up an Intent from within the main activity, it launches fine. In case it matters, here is the Android Manifest file: <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.steve" android:versionCode="1" android:versionName="1.0"> <application android:icon="@drawable/icon" android:label="@string/app_name"> <activity android:name=".Volume_Change_Program" android:label="@string/app_name"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> <activity android:name=".WidgetTest" android:label="@string/hello"> <intent_filter> <action android:name="android.intent.action.MAIN"/> <category android:name="android.intent.category.LAUNCHER"/> </intent_filter> </activity> <receiver android:name=".VolumeChangerWidget" > <intent-filter> <action android:name="android.appwidget.action.APPWIDGET_UPDATE" /> </intent-filter> <meta-data android:name="android.appwidget.provider" android:resource="@xml/volume_changer_info" /> </receiver> </application> <uses-sdk android:minSdkVersion="3" /> Is there a way to test where the fault is? I.e. is the fault that the button isn't linked properly to the PendingIntent, or that the PendingIntent or Intent isn't finding WidgetTest.class, etc? Thanks very much for your help! Steve

• In Python how do I sort a list of dictionaries by values of the dictionary?

  - by masi

  I got a list of dictionaries and want that to be sorted by a value of that dictionary. This [{'name':'Homer', 'age':39}, {'name':'Bart', 'age':10}] sorted by name, should become [{'name':'Bart', 'age':10}, {'name':'Homer', 'age':39}]

• JFall 2012

  - by Geertjan

  JFall 2012 was over far too soon! Seven tracks going on simultaneously in a great location, with many artifacts reminding me of JavaOne, and nice snacks and drinks afterwards. The day started, as such things always do, with a keynote. Thanks to @royvanrijn for the photo below, I didn't take any myself and without a picture this report might have been too dry: What you see above is Steve Chin riding into the keynote hall on his NightHacking bike. The keynote was interesting, I can't be too complimentary about it, since I was part of it myself. Bert Ertman introduced the day and then Steve Chin took over, together with Sharat Chander, Tom Eugelink, Timon Veenstra, and myself. We had a strict choreography for the keynote, one that would ensure a lot of variation and some unexpected surprises, such as Steve being thrown off the stage a few times by Bert because of mentioning JavaOne too many times, rather than the clearly much cooler JFall. Steve talked about JavaOne and the direction Java is headed in, Sharat talked about JavaME and embedded devices, Steve and Tom did a demo involving JavaFX, I did a Project Easel demo, and Timon from Ordina talked about his Duke's Choice Award winning AgroSense project. I think the Project Easel demo (which I repeated later in a screencast for Parleys arranged by Eugene Boogaart) came across well and several people I spoke to especially like the roundtrip/bi-directional work that can be done, from browser to IDE and back again, very simply and intuitively. (In a long conversation on the drive back home afterwards, the scenario of a designer laying out the UI in HTML and then handing the HTML to a developer for back-end work, a developer who would then find it convenient to open the HTML in a browser and quickly navigate from the browser to the resources within the IDE, was discussed and considered to be extremely interesting and worth considering adopting NetBeans for, for no other reason than that.) Later I attended a session by David Delabassee on Java EE 7, Hans Dockter on Gradle, and Sander Mak on cross-build injection attacks. I was sorry to have missed Martijn Verburg's session, which sounded like it was really fantastic, among others, such as Gerrit Grunwald. I did a session too, entitled "Unlocking the Java EE 6 Platform", which was very well attended, pretty much a full room, and the demo went very smoothly. I talked to many people, e.g., a long time with Hans Dockter about how cool Gradle is and how great the Gradle/NetBeans plugin is turning out to be. I also had a long conversation (and did a demo) with Chris Chedgey, from Structure101, after his session, which was incredibly well attended; very interesting how popular modularity is. I met several people for the first time, as well as some colleagues from past places I've worked at. All in all, it was a great conference, unfortunately too short, which was very well attended (clearly over 1000) people, with several international speakers, as well as international attendees such as Mattias Karlsson, Sweden JUG leader. And, unsurprisingly, I came across NetBeans Platform applications again, none of which I had ever heard of before. In each case, "our fat client application" was mentioned in passing, never as a main application, and never in a context where there are plans for the application to be migrated to the web or mobile, simply because doing so makes no business sense at all. Great times at JFall, looking forward to meeting with some of the people I met again soon.

• Ruby concatenate strings and add spaces

  - by David Oneill

  I have 4 string variables name, quest, favorite_color, speed that might be empty. I want to concatenate them all together, putting spaces between those that aren't empty. So: name = 'Tim' quest = 'destroy' favorite_color = 'red' speed = 'fast' becomes 'Tim destroy red fast' and name = 'Steve' quest = '' favorite_color = '' speed = 'slow' becomes: 'Steve slow' (Notice: there is only 1 space between 'Steve' and 'slow') How do I do that (preferably in 1 line).

• Kill a 10 minute old zombie process in linux bash script

  - by Steve

  I've been tinkering with a regex answer by yukondude with little success. I'm trying to kill processes that are older than 10 minutes. I already know what the process IDs are. I'm looping over an array every 10 min to see if any lingering procs are around and need to be killed. Anybody have any quick thoughts on this?

• Searches (and general querying) with HBase and/or Cassandra (best practices?)

  - by alexeypro

  I have User model object with quite few fields (properties, if you wish) in it. Say "firstname", "lastname", "city" and "year-of-birth". Each user also gets "unique id". I want to be able to search by them. How do I do that properly? How to do that at all? My understanding (will work for pretty much any key-value storage -- first goes key, then value) u:123456789 = serialized_json_object ("u" as a simple prefix for user's keys, 123456789 is "unique id"). Now, thinking that I want to be able to search by firstname and lastname, I can save in: f:Steve = u:384734807,u:2398248764,u:23276263 f:Alex = u:12324355,u:121324334 so key is "f" - which is prefix for firstnames, and "Steve" is actual firstname. For "u:Steve" we save as value all user id's who are "Steve's". That makes every search very-very easy. Querying by few fields (properties) -- say by firstname (i.e. "Steve") and lastname (i.e. "l:Anything") is still easy - first get list of user ids from "f:Steve", then list from "l:Anything", find crossing user ids, an here you go. Problems (and there are quite a few): Saving, updating, deleting user is a pain. It has to be atomic and consistent operation. Also, if we have size of value limited to some value - then we are in (potential) trouble. And really not of an answer here. Only zipping the list of user ids? Not too cool, though. What id we want to add new field to search by. Eventually. Say by "city". We certainly can do the same way "c:Los Angeles" = ..., "c:Chicago" = ..., but if we didn't foresee all those "search choices" from the very beginning, then we will have to be able to create some night job or something to go by all existing User records and update those "c:CITY" for them... Quite a big job! Problems with locking. User "u:123" updates his name "Alex", and user "u:456" updates his name "Alex". They both have to update "f:Alex" with their id's. That means either we get into overwriting problem, or one update will wait for another (and imaging if there are many of them?!). What's the best way of doing that? Keeping in mind that I want to search by many fields? P.S. Please, the question is about HBase/Cassandra/NoSQL/Key-Value storages. Please please - no advices to use MySQL and "read about" SELECTs; and worry about scaling problems "later". There is a reason why I asked MY question exactly the way I did. :-)

• IUSR account and SCCM 2007 R3 agent

  - by steve schofield

  I recently started working with SCCM and rolling the agent out with machine having IIS 7.x installed.  I ran into issues where the SCCM agent wouldn't install.  The errors mostly were 0x80004005 and 1603, another key one I found was Return Value 3 in the SCCM setup log.  During the troubleshooting, I found a cool utility called WMI Diag  WMI diag is a VBS script that reads the local WMI store and helps diagnose issue.  Anyone working with SMS or SCCM should keep this handy tool around.  The good thing my particular case WMI was healthy.  The issue turned out I changed the Anonymous Authentication module from using the IUSR account to inherit Application Pool identity.  Once we temporarily switched back to IUSR, installed the agent, then switched the setting back to inherit application pool identity, the SCCM agent installed with no issues. I'm not sure why switching back to the IUSR account solved my issue, if I find out I'll update the post.  More information on IIS 7 builtin accounts http://learn.iis.net/page.aspx/140/understanding-built-in-user-and-group-accounts-in-iis-7 Specify an application pool identity  http://technet.microsoft.com/en-us/library/cc771170(WS.10).aspx SCCM resources (Config Mgr Setup  / Deployment forums) http://social.technet.microsoft.com/Forums/en-US/configmgrsetup/threads http://www.myitforum.com (the best independent SCCM community resource) Hope this helps.
