• apcupsd on Linux does not report on APC BackUPS Pro 900

  - by lserni

  From what documentation I could find, the UPS should be (is!) supported by Linux and ought to work with apcupsd. I looked for specific problems such as the infamous Microlink protocol, and found none. I have found a feedback from a guy in UK that reports using this very model on a not-too-different OS version (his OpenSuSE 12.1, mine 12.3 x86_64). The USB port is detected, lsusb reports Bus 002 Device 003: ID 051d:0002 American Power Conversion Uninterruptible Power Supply and lsusb -v -s002:003 confirms and expands: Bus 002 Device 003: ID 051d:0002 American Power Conversion Uninterruptible Power Supply Device Descriptor: bLength 18 bDescriptorType 1 bcdUSB 2.00 bDeviceClass 0 (Defined at Interface level) bDeviceSubClass 0 bDeviceProtocol 0 bMaxPacketSize0 64 idVendor 0x051d American Power Conversion idProduct 0x0002 Uninterruptible Power Supply bcdDevice 0.90 iManufacturer 1 American Power Conversion iProduct 2 Back-UPS RS 900G FW:879.L4 .I USB FW:L4 bNumConfigurations 1 Configuration Descriptor: [...] Interface Descriptor: [...] bInterfaceClass 3 Human Interface Device bInterfaceSubClass 0 No Subclass bInterfaceProtocol 0 None iInterface 0 HID Device Descriptor: bLength 9 bDescriptorType 33 bcdHID 1.00 bCountryCode 33 US bNumDescriptors 1 bDescriptorType 34 Report wDescriptorLength 1134 Report Descriptors: ** UNAVAILABLE ** Endpoint Descriptor: bLength 7 bDescriptorType 5 bEndpointAddress 0x81 EP 1 IN bmAttributes 3 Transfer Type Interrupt Synch Type None Usage Type Data wMaxPacketSize 0x0008 1x 8 bytes bInterval 100 Device Status: 0x0000 (Bus Powered) The kernel recognizes this and duly sets up crw------- 1 root root 180, 96 Nov 4 16:11 /dev/usb/hiddev0 As far as I know, everything is as it should be.

This confirms that it's not the Microlink problem, or it would report the battery status, if precious little else. If I disconnect the USB cable, I get an apcupsd message to the effect that communications have been lost; and I get the "communication restored" broadcast too, if I reconnect the cable. apcupsd is monitoring. So everything tells me that it should work -- only it doesn't. Does anyone spot what I'm missing?

• usb_modeswitch not switching

  - by deniz

  After I upgraded from kernel 2.6.18 to 3.5.3 modeswitch started not to work for me. Although lsusb shows my usb modem, usb_modeswitch does not switch it. My system information is like below. I ran lsusb, dmesg, usb-devices and usb_modeswitch their output is like below. usb_modeswitch instead of switching my modem it says "No devices in default mode found. Nothing to do. Bye.".

• Empty $_POST data

  - by Antimony

  I am trying to post a post to my MyBB server from a Python script, but try as I might, I can't get it to work. The request shows up in the forensic log and the headers are in the $_SERVER variable, but $_POST is always an empty array. The error log shows nothing, even at the debug level. I've already tried searching, but I haven't found anything that's helped. I already checked the post_max_size thing, which is 8M. Another factor is that it's just my own requests which aren't going through. Browser generated requests seem to do just fine. I've looked and looked, but I can't find anything I'm doing differently that should matter. Anyway, here is an example request.

• Hidden DNS master only sending notify to one slave

  - by Rob

  My hidden DNS master is only sending notifies to one of the name servers for a zone I have 3 named servers ns0,ns1 & ns2 all running bind 9.7.3.dfsg-1ubuntu4.1. When an update is processed the master (ns0) seems to behave normally. ns0 (192.168.2.50) zone domain.org/IN: sending notifies (serial 2012060703) client 192.168.2.52#42892: transfer of 'domain.org/IN': AXFR-style IXFR started: TSIG rndc-key client 192.168.2.52#42892: transfer of 'domain.org/IN': AXFR-style IXFR ended ns2 (192.168.2.52) client 192.168.2.50#3762: received notify for zone 'domain.org': TSIG 'rndc-key' zone domain.org/IN: Transfer started. transfer of 'domain.org/IN' from 192.168.2.50#53: connected using 192.168.2.52#55747 zone domain.org/IN: transferred serial 2012060704: TSIG 'rndc-key' transfer of 'domain.org/IN' from 192.168.2.50#53: Transfer completed: 1 messages, 34 records, 1028 bytes, 0.001 secs (1028000 bytes/sec) Nothing happens on ns1. I've turned up the logging level but there's no information in syslog about the actual name servers bind has sent notifications to so I guess this is something it doesn't log. I've also tried watching tcpdump, it never makes any attempt to notify ns1 only ns2 192.168.2.50.56278 > 192.168.2.52.53: [udp sum ok] 56418 notify [b2&3=0x2400] [1a] [1au] ?

I was under the impression bind would automatically send notifies to all NS records on a zone, maybe it's bugged?

• udp expected behaviour not responding to test result

  - by ernst

  I have a local network topology that is structured as follows: three hosts and a switch in the middle. I am using a switch that supports 10,100,1000 Mbit/s full/half duplex connection. I have configured the hosts with a static ip 172.16.0.1-2-3/25. This is the output of ifconfig eth0 Link encap: Ethernet HWaddr ***** inet addr:172.16.0.3 Bcast:172.16.0.127 Mask:255.255.255.128 UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) Interrupt:16 The output on H1 and H2 is perfectly matchable They are mutually reachable since i have tested the network with ping.

• Samba share not accessible from Win 7 - tried advice on superuser

  - by Roy Grubb

  I have an old Red Hat Linux box that I use, amongst other things, to run Samba. My Vista and remaining Win XP PC can access the p/w-protected Samba shares. I just set up a new Windows 7 64-bit Pro PC. Attempts to access the Samba shares by clicking on the Linux box's icon in 'Network' from this machine gave a Logon failure: unknown user name or bad password. message when I gave the correct credentials. So I followed the suggestions in Windows 7, connecting to Samba shares (also checked here but found LmCompatibilityLevel was already 1). This got me a little further. If click on the Linux box's icon in 'Network' from this machine I now see icons for the shared directories. But when I click on one of these, I get \\LX\share is not accessible. You might not have permission... etc. I tried making the Win 7 password the same as my Samba p/w (the user name was already the same). Same result. The Linux box does part of what I need for ecommerce - the in-house part, it's not accessible to the Internet. As my Linux Fu is weak, I have to avoid changes to the Linux box, so I'm hoping someone can tell me what to do to Win 7 to make it behave like XP and Vista when accessing this share. Help please!? Thanks Thanks for replying @Randolph. I had set 'Network security: LAN Manager authentication level' to Send LM & NTLM - use NTLMv2 session security if negotiated based on the advice in Windows 7, connecting to Samba shares and had restarted the machine, but that didn't work for me. I'll try playing with other Network security values. I have now tried the following: Network security: Allow Local System to use computer identity for NTLM: changed from Not Defined to "Enabled". Restarted machine Still says "\LX\share is not accessible. You might not have permission..." etc. Network security: Restrict NTLM: Add remote server exceptions for NTLM Authentication (added LX) Restarted machine Still says "\LX\share is not accessible. You might not have permission..." etc. I can't see any other Network security settings that might affect this. Any other ideas please? Thanks Roy

• A dusty server room

  - by pauska

  Here's the story.. The owners of the building we lease office space from decided to do a renovation of the exterior. This involved in some pretty heavy work at the level where our server room is, including exchanging windows wich are fit inside a concrete wall. My red alert went off when I heard that they were going to do the same thing with our server room (yes, our server room has a window. We're a small shop with 3 racks. The window is secured with steel bars.) I explicity told the contractor that they need to put up a temporarily wall between our racks and the original wall - and to make sure that the temporary wall is 100 % air and water-tight. They promised to do so. The temporary wall has a small door in it, so that workers can go in/out through the day (through our server room, wich was the only option....). On several occasions I could find the small door half-way shut while working evenings/nights. I locked the door, and thought that they would hopefully get the point soon and keep the door shut. I even gave a electrician a mouthful when I saw that he didn't close the door properly. By this point - I bet that most of you get a picture of what happened. Yes, they probably left the door open while drilling in the concrete. I present you our 4 weeks old EMC VNX: I'll even put in a little bonus, here is the APC UPS one rack further away from the temporary wall. See the nice little landing strip from my finger? What should I do? The only thing that comes to mind is to either call all our suppliers (EMC, HP, Dell, Cisco) and get them to send technicians to check out all the gear in the server room, or get some kind of certified 3rd-party consulant to check all of it. Would you run production systems on this gear? How long? Edit: I should also note that our aircondition isn't exactly enterprise-grade, given the nature of our small room. It's just a single inverter, wich have failed one time before I started working here (failed inverters usually leads to water dripping out).

• php-fpm or nginx: bad gateway

  - by John Tate

  I'm getting a bad gateway error all the sudden for a site. I didn't change the configuration for the site, I just added a new server config where I put them under /etc/nginx/servers and it stopped working. The new server works, and there is no conflict between the php-fpm listen addresses. server { listen 80; server_name obfuscated.onion; location = / { root /var/www/sites/obfuse; index index.php; } location / { root /var/www/sites/obfuse; index index.php; if (!-f $request_filename) { rewrite ^(.*)$ /index.php?q=$1 last; break; } if (!-d $request_filename) { rewrite ^(.*)$ /index.php?q=$1 last; break; } } error_page 404 /index.php; location ~* ^.+.(jpg|jpeg|gif|css|png|js|ico)$ { root /var/www/sites/obfuse; access_log off; expires 30d; } location ~ \.php$ { fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME /var/www/sites/obfuse$fastcgi_script_name; fastcgi_param QUERY_STRING $query_string; fastcgi_param REQUEST_METHOD $request_method; fastcgi_param CONTENT_TYPE $content_type; fastcgi_param CONTENT_LENGTH $content_length; fastcgi_param PATH_INFO $fastcgi_script_name; include fastcgi_params; } } There is nothing unusual in php-fpm's log even when I raised the level to debug.

• Finding underlying cause of Window 7 Account corruption.

  - by Carl Jokl

  I have been having trouble with my Sister's computer which I built. It is running Windows 7 Ultimate x64. The problem is that I have had problems with the accounts becoming corrupted. First problems manifest themselves in the form of Windows saying the profile failed to be loaded properly and a temporary profile. Eventually the account will not allow login at all. An error message along the lines the authentication service failing the login. I have found information about this problem and how to fix it. The problem being that something has corrupted the account profile and backing up and recreating the accounts fixes the problem. I have been able to fix things and get logins working again but over the period of usually about a week it happens again. Bit by bit the accounts corrupt and then it is back to square one. I am frustrated because I don't know what the underlying cause of the problem is i.e. what is causing the accounts to be corrupted in the first place. At the moment I am just treating the symptoms. I was hoping someone who may have more experience with dealing with this problem might be able to help me find the root cause. Some articles suggest that Norton Internet Security is a big culprit of this problem which is installed. I could try uninstalling Norton and see if it helps. The one thing which is different about this computer to any other I have built is that it has a solid state drive. Actually it has both a hard drive and solid state drive. The documents and settings i.e. the Users directory is stored on the hard drive. This was done following an article about moving the user account data onto a separate drive on Windows 7 which I found on the Internet. Moving the User accounts is more of a pain under Windows 7 and this solution involved creating a low level file system link to the folder from the boot drive (Solid State) to the Hard Drive. The idea is that the computer behaves just as if it is accessing the User's folder from the boot drive but actually the data is stored on the hard drive. This may have nothing to do with the cause of the problem but due to the problem being user account corruption it is a possibility I have not been able to rule out. Any help would be appreciated as I would be glad to see the back of this problem.

• Unable to delete all partitions on flash drive using Windows 7 OS??

  - by irrational John

  Recently I purchased an ADATA C802 8GB flash drive. Since the drive was new I decided to run some of the HD Tune Pro (v4.50) performance tests on it, mostly just for the heck of it. To avoid accidently destroying data HD Tune refuses to write to a drive unless there are no partitions on the drive. If you do attempt to write to a drive with partitions, it posts the message "Writing is disabled. To enable writing please remove all partitions." As you would expect, the ADATA came formatted with a single primary FAT32 partition in the Master Boot Record. But a number of unexpected things happened when I attempted to delete that partition. The first thing I tried was to use the Windows 7 (64-bit) Disk Management tool (diskmgmt.msc) to delete the partition. It would not let me. The context menu choice to delete that volume was not available. Next I opened up a command prompt window with Admin authority and ran diskpart. Diskpart deleted the volume for me. However, when I attempted to run an HD Tune write test on the drive I still got the "Writing is disabled" message. Huh??? So I fired up a utility I have which allows viewing drives at the sector level and verified that the partition table in the Master Boot Record was empty. No partitions. Yet HD Tune still thought there were partitions on the drive? So why was I still getting the "Writing is disabled" message from HD Tune Pro? And why wouldn't the Windows 7 Disk Management tool let me change the partitions on this drive. After doing the above, I plugged the ADATA into my MacBook. I was then able to format it as either a GPT or MBR partitioned drive with no problems. I am not looking for suggestions on how to format this drive. I can do that. What I do not understand and was hoping I might get insight into is why this drive behaves so strangely under Windows 7? And BTW, what's up with HD Tune Pro? BTW, if I plug the drive I formatted on my MacBook back into my Windows 7 64-bit system I still run into road blocks with the Disk Management tool. For example, I cannot delete all the GPT partitions on the ADATA so I can convert it into an MBR drive. I following Microsoft's instructions, the instructions just do not work with this ADATA flash drive. Anyone know what's up with this? It makes no sense to me. Has something changed in Windows 7 (Vista)??

• Simple mdadm RAID 1 not activating spare

  - by Nick Liu

  I had created two 2TB HDD partitions (/dev/sdb1 and /dev/sdc1) in a RAID 1 array called /dev/md0 using mdadm on Ubuntu 12.04 LTS Precise Pangolin. The command sudo mdadm --detail /dev/md0 used to indicate both drives as active sync. Then, for testing, I failed /dev/sdb1, removed it, then added it again with the command sudo mdadm /dev/md0 --add /dev/sdb1 watch cat /proc/mdstat showed a progress bar of the array rebuilding, but I wouldn't spend hours watching it, so I assumed that the software knew what it was doing. After the progress bar was no longer showing, cat /proc/mdstat displays: md0 : active raid1 sdb1[2](S) sdc1[1] 1953511288 blocks super 1.2 [2/1] [U_] And sudo mdadm --detail /dev/md0 shows: /dev/md0: Version : 1.2 Creation Time : Sun May 27 11:26:05 2012 Raid Level : raid1 Array Size : 1953511288 (1863.01 GiB 2000.40 GB) Used Dev Size : 1953511288 (1863.01 GiB 2000.40 GB) Raid Devices : 2 Total Devices : 2 Persistence : Superblock is persistent Update Time : Mon May 28 11:16:49 2012 State : clean, degraded Active Devices : 1 Working Devices : 2 Failed Devices : 0 Spare Devices : 1 Name : Deltique:0 (local to host Deltique) UUID : 49733c26:dd5f67b5:13741fb7:c568bd04 Events : 32365 Number Major Minor RaidDevice State 1 8 33 0 active sync /dev/sdc1 1 0 0 1 removed 2 8 17 - spare /dev/sdb1 I've been told that mdadm automatically replaces removed drives with spares, but /dev/sdb1 isn't being moved into the expected position, RaidDevice 1. UPDATE (30 May 2012): A badblocks destructive read-write test of the entire /dev/sdb yielded no errors as expected; both HDDs are new. As of the latest edit, I assembled the array with this command: sudo mdadm --assemble --force --no-degraded /dev/md0 /dev/sdb1 /dev/sdc1 The output was: mdadm: /dev/md0 has been started with 1 drive (out of 2) and 1 rebuilding. Rebuilding looks like it's progressing normally: md0 : active raid1 sdc1[1] sdb1[2] 1953511288 blocks super 1.2 [2/1] [U_] [>....................] recovery = 0.6% (13261504/1953511288) finish=2299.7min speed=14060K/sec unused devices: <none> I'm now waiting on this rebuild, but I'm expecting /dev/sdb1 to become a spare just like the five or six times that I've tried rebuilding before. UPDATE (31 May 2012): Yeah, it's still a spare. Ugh! UPDATE (01 June 2012): I'm trying Adrian Kelly's suggested command: sudo mdadm --assemble --update=resync /dev/md0 /dev/sdb1 /dev/sdc1 Waiting on the rebuild now... My questions are: Why isn't the spare drive becoming active sync? How can I make the spare drive become active?

• JNDI Datasource definition in Tomcat 6.0

  I want to define a DataSource to an Oracle database on my Tomcat 6.0. So, in conf/server.xml (yes, I know that this DataSource will be available for all the webapps in Tomcat, but it's not a problem here), I've set this Resource: <GlobalNamingResources> <Resource name="hibernate/HibernateDS" auth="Container" type="javax.sql.DataSource" url="jdbc:oracle:thin:@myserver:1542:foo" username="foo" password="bar" driverClassName="oracle.jdbc.OracleDriver" maxActive="50" maxIdle="10" validationQuery="select 1 from dual"/> Then, in the web.xml of my application, I set a resource-ref element: <resource-ref> <description>Hibernate Datasource</description> <res-ref-name>hibernate/HibernateDS</res-ref-name> <res-type>javax.sql.DataSource</res-type> <res-auth>Container</res-auth> </resource-ref> Finally, as Hibernate is used to manage the database connection, I have a webapps/mywebapp/WEB-INF/classes/hibernate.cfg.xml that creates a session-factory using the JNDI DataSource: <hibernate-configuration> <session-factory> <property name="connection.datasource">java:comp/env/hibernate/HibernateDS</property> ...

• What's the best way to do user profile/folder redirect/home directory archiving?

  - by tpederson

  My company is in dire need of a redesign around how we handle user account administration. I've been tasked with automating the process. The end goal is to have the whole works triggered by the business, and IT only looking in when there's an error reported. The interim phase is going to be semi-manual. That is a level 2 tech inputs the user's info and supervises the process. The current hurdle I'm facing is user profile archiving. Our security team requires us to archive the profile directories for any terminated user for 60 days in case the legal team requires access to their files. Our AD is as much a mess as everything else, so there are some users with home directories and some with profiles. Anyone who has a profile dir in AD also has a good deal of their profile redirected to our file servers over DFS. In order to complete the process manually you find the user in AD, disable them, find their home/profile dir, go there and take ownership, create an archive folder, move all their files over, then delete the old dir. Some users have many many gigs of nonsense and this can take quite some time. Even automated the process would not be a quick one. I'm thinking that I need to have a client side C# GUI for the quick stuff and some server side batch script or console app to offload this long running process. I have a batch script that works decently using takeown and robocopy, but I wonder if a C# console app would do a better job. So, my question at long last is, what do you think is the best way to handle this? I can't imagine this is a unique problem, how do other admins get this done? The last place I worked was easily 10x larger than the place I'm in now. If we would have been doing this manual crap there, they'd have needed a team of at least 30 full time workers to keep up. I have decent skills in C#.net and batch scripting, but am a quick study and I have used most every language once or twice. Thank you for reading this and I look forward to seeing what imaginative solutions you all can come up with.

• Hot-swap drive got new name, can I change it on-the-fly?

  - by T.J. Crowder

  One of the HDDs in my server's RAID config failed, so I took it out of the array and had the data center hot-swap it. They've done that, but now the new drive is /dev/sdc rather than /dev/sda. I suspect — correct me if I'm wrong — that if I reboot the server, it will be /dev/sda again, so I'm hesitant to add it back to the array as /dev/sdc because I don't want to lay a trap for myself to fall into on the next reboot. I'd just as soon not reboot the server if I don't need to (if I do need to, well, too bad for me). Is there a way I can change the device name from /dev/sdc to /dev/sda without rebooting? This is on Ubuntu 10.04 LTS. It's an md array ("Linux Software RAID"), where currently one of the devices (there are a couple of them) looks like this ("degraded" because I've removed the old /dev/sda from it): # mdadm --detail /dev/md0 /dev/md0: Version : 00.90.03 Creation Time : Sun Oct 11 21:07:54 2009 Raid Level : raid1 Array Size : 97536 (95.27 MiB 99.88 MB) Used Dev Size : 97536 (95.27 MiB 99.88 MB) Raid Devices : 2 Total Devices : 1 Preferred Minor : 0 Persistence : Superblock is persistent Update Time : Thu Jun 30 09:31:16 2011 State : clean, degraded Active Devices : 1 Working Devices : 1 Failed Devices : 0 Spare Devices : 0 UUID : 496be7a5:ab9177ed:7792c71e:7dc17aa4 Events : 0.112 Number Major Minor RaidDevice State 0 8 17 0 active sync /dev/sdb1 1 0 0 1 removed Thanks, Update: Reading through the kernel md documentation, I suspect that if the name changes on reboot, it won't matter. (Good design, that.) Here's why: Boot time autodetection of RAID arrays When md is compiled into the kernel (not as module), partitions of type 0xfd are scanned and automatically assembled into RAID arrays. This autodetection may be suppressed with the kernel parameter "raid=noautodetect". As of kernel 2.6.9, only drives with a type 0 superblock can be autodetected and run at boot time. The kernel parameter "raid=partitionable" (or "raid=part") means that all auto-detected arrays are assembled as partitionable. I do have md compiled into the kernel, so I'm rebuilding the array now and will do the reboot to see what happens. Even if it works, the above doesn't answer the question I actually asked, so unless someone comes along and answers that question in the meantime (I'd be interested, even if it's not necessary for what I'm doing this very moment), I'll just delete the question to keep noise down.

• IIS httpTracing setting has no effect

  - by digahill

  I'm trying to troubleshoot some performance issues we are having on a specific ASP.NET page with Microsoft's Perfecto Tool on IIS 7.5. Perfecto uses the ETW hooks build in to IIS to report on specific HTTP request, and is working quite well. However, I only want IIS to emit traces for one specific page, say "Default.aspx" in my TestApp Web Application. Following the instructions on the httpTracing man page, I should be able to add the traceUrls element to my root web.config file for TestApp. This doesn't seem to affect tracing whatsoever when I do so. For example, I've used the following settings in the web.config file and every request that hits the IIS server is sending tracing messages that are in turn picked up by Perfecto. (In the System.WebServer section) <httpTracing> <traceUrls> <add value="/Default.aspx" /> </traceUrls> </httpTracing> I then found that the applicationHost.config file on the server had an empty element. I tried removing this element, as well as the httpTracing element in the web.config. After a machine reboot, I was still getting tracing messages! My understanding is that the presense of the httpTracing element is what controlls whether ETW tracing is on or not. I ensured there was no reference to httpTracing in the machine.config, too. At a loss, I decided to remove the IIS Tracing feature with Server Manager. After a reboot, I no longer got ETW tracing. I then reinstalled IIS Tracing feature with Server Manager. As expected, the httpTracing element reappeared in the applicationhost.config file. Tracing messages began sending again for all sites and pages. I then tried to use the traceUrls element at the applicationhost.config level. This also didn't filter out and traces. I must be misunderstanting something key with how httpTracing works. There aren't many resources on the web to help me, either. Can anyone tell me if what I'm trying should work? Has anyone else had success filtering tracing message per page with traceUrls? I should note that I also tried changing with the following setting in applicationhost.config to "allow". It didn't seem to help. <section name="httpTracing" overrideModeDefault="Allow" />

• flashcache with mdadm and LVM

• Can Vagrant point to a directory of Puppet manifests for execution?

  - by SeligkeitIstInGott

  I am using Vagrant to jump start some initial Puppet config and am confused on how to include/run multiple manifests (other than just site.pp) in the puppet execution workflow without making the extra manifests into modules and including them that way. In the puppet manifests directory that I point Vagrant to (see below) I have two manifests that I want executed: site.pp and hierasetup.pp. config.vm.provision "puppet" do |puppet| puppet.manifests_path = "puppet_files/manifests" puppet.module_path = "puppet_files/modules" puppet.manifest_file = "site.pp" puppet.options = "--verbose --debug" end Currently I am having site.pp be the manifest that calls hierasetup.pp. My site.pp looks like this: File { owner => 'root', group => 'root', mode => '0644', } import "hierasetup.pp" include jboss But I get this error about the deprecation of "import": Warning: The use of 'import' is deprecated at /tmp/vagrant-puppet-1/manifests/site.pp:33. See http://links.puppetlabs.com/puppet-import-deprecation (at grammar.ra:610:in `_reduce_190') According to the referenced URL under "Things to try instead" it says "To keep your node definitions in separate files, specify a directory as your main manifest". Further this puppet doc on main manifests says: "Recommended: If you’re using the main manifest heavily instead of relying on an ENC, consider changing the manifest setting to $confdir/manifests. This lets you split up your top-level code into multiple files while avoiding the import keyword. It will also match the behavior of simple environments." It appears that Puppet can reference an entire directory instead of just a specific manifest file, such that I would expect that Vagrant would make a provision for this and allow me to drop the "puppet.manifest_file = "site.pp" line and point to the parent directory instead in which all the *.pp files there will be executed. However removing that line in Vagrant merely generates a complaint about an expected "default.pp" in its stead: puppet provisioner: * The configured Puppet manifest is missing. Please specify a path to an existing manifest: /some/path/puppet_files/manifests/default.pp So: Firstly, do I understand the "new" (non-import) way of calling multiple manifests correctly, in that a directory is to be pointed to in which all the *.pp files inside it will be executed? And secondly, has Vagrant "caught up" with this new change to accommodate the referencing of directories in conjunction with Puppet's deprecation of "import"? Update: Thanks to Shane the issue with #2 (Vagrant's code not being caught up to allow pointing to puppet manifest directories) was reported on Vagrant's GitHub issue tracker site and has since been patched: https://github.com/mitchellh/vagrant/issues/4169

• Bypassing "Found New Hardware Wizard" / Setting Windows to Install Drivers Automatically

  - by Synetech inc.

  Hi, My motherboard finally died after the better part of a decade, so I bought a used system. I put my old hard-drive and sound-card in the new system, and connected my old keyboard and mouse (the rest of the components—CPU, RAM, mobo, video card—are from the new system). I knew beforehand that it would be a challenge to get Windows to boot and install drivers for the new hardware (particularly since the foundational components are new), but I am completely unable to even attempt to get through the work of installing drivers for things like the video card because the keyboard and mouse won't work (they do work, in the BIOS screen, in DOS mode, in Windows 7, in XP's boot menu, etc., just not in Windows XP itself). Whenever I try to boot XP (in normal or safe mode), I get a bunch of balloons popping up for all the new hardware detected, and a New Hardware Found Wizard for Processor (obviously it has to install drivers for the lowest-level components on up). Unfortunately I cannot click Next since the keyboard and mouse won't work yet because the motherboard drivers (for the PS/2 or USB ports) are not yet installed. I even tried a serial mouse, but to no avail—again, it does work in DOS, 7, etc., but not XP because it doesn't have the serial port driver installed. I tried mounting the SOFTWARE and SYSTEM hives under Windows 7 in order to manually set the "unsigned drivers warning" to ignore (using both of the driver-signing policy settings that I found references to). That didn't work; I still get the wizard. They are not even fancy, proprietary, third-party, or unsigned drivers. They are drivers that come with Windows—as the drivers for CPU, RAM, IDE controller, etc. tend to be. And the keyboard and mouse drivers are the generic ones at that (but like I said, those are irrelevant since the drivers for the ports that they are connected to are not yet installed). Obviously at some point in time over the past several years, a setting got changed to make Windows always prompt me when it detects new hardware. (It was also configured to show the Shutdown Event Tracker on abnormal shutdowns, so I had to turn that off so that I could even see the desktop.) Oh, and I tried deleting all of the PNF files so that they get regenerated, but that too did not help. Does anyone know how I can reset Windows to at least try to automatically install drivers for new hardware before prompting me if it fails? Conversely, does anyone know how exactly one turns off automatic driver installation (and prompt with the wizard)? Thanks a lot.

• Looking for advice on Hyper-v storage replication

  - by Notre1

  I am designing a 2-host Hyper-V R2 cluster with 6-10 guests stored on a SMB iSCSI SAN device (probably Promise VessRAID). I will be getting at least two of the SAN devices and need to eliminate the storage a single point of failure. Ideally, that would involve real-time failover for the storage, like the Windows failover clustering does for the hosts. This design will be used at around six of our sites, and I would like to allow for us to eventually setup a cluster at colocation site and replicate each site's VMs there for DR. (Ideally a live multi-site cluster, but a manual import of the VMs would be fine for this sort of DR.) The tools that come with enterprise SANs, like EMC and NetApp, seem to be the most commonly used items for a Hyper-V cluster, but I can't afford their prices with my budget. Outside of them, the two tools that seem to be most common for Hyper-V storage replication are SteelEye (now SIOS) DataKeeper Cluster Edition and Double-Take Availability. Originally, I was planning on using Clustered Shared Volume(s) (CSV), but it seems like replication support for these is either not available or brand new in both these products. It looks like CSVs are supported in Double-Take 5.22, see this discussion, but I don't think I want to run something that new in production. Right now, it seems like the best option for me is not to implement CSVs, implement some sort of storage replication, and upgrade to CSVs at a later date once replicating them is more mature. I would love to have live migration, and CSVs are not required for live migration if you are using one LUN per VM, so I guess this is what I'll do. I would prefer to stick to the using the Microsoft Windows Server and Hyper-V tools and features as much as possible. From that standpoint, SteelEye looks more appealing than Double-Take because they make the DataKeeper volume(s) available to the Failover Clustering Manager and then failover clustering is all configured and managed through the native Microsoft tools. Double-Take says that "clustered Hyper-V hosts are not supported," and Double-Take Availability itself seems to be what is used for the actual clustering and failover. Does anyone know if any of these replication tools work with more than two hosts in the cluster? All the information I can find on the web only uses two hosts in their examples. Are there any better tools than SteelEye and Double-Take for doing what I am trying to do, which is eliminate the storage as as single point of failure? Neverfail, AppAssure, and DataCore all seem to offer similar functionality, but they don't seems to be as popular as SteelEye and Double-Take. I have seen a number of people suggest using Starwind iSCSI SAN software for the shared storage, which includes replication (and CSV replication at that). There are a couple of reasons I have not seriously considered this route: 1) The company I work for is exclusively a Dell shop and Dell does not have any servers with that I can pack with more than six 3.5" SATA drives. 2) In the future, it could be advantegous for us to not be locked into a particular brand or type of storage and third-party replication softwares all allow replication to heterogeneous storage devices. I am pretty new to iSCSI and clustering, so please let me know if it looks like I am planning something that goes against best practices or overlooking/missing something.

• How to get an inactive RAID device working again?

  - by Jonik

  After booting, my RAID1 device (/dev/md_d0 *) sometimes goes in some funny state and I cannot mount it. * Originally I created /dev/md0 but it has somehow changed itself into /dev/md_d0. # mount /opt mount: wrong fs type, bad option, bad superblock on /dev/md_d0, missing codepage or helper program, or other error (could this be the IDE device where you in fact use ide-scsi so that sr0 or sda or so is needed?) In some cases useful info is found in syslog - try dmesg | tail or so The RAID device appears to be inactive somehow: # cat /proc/mdstat Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4] [raid10] md_d0 : inactive sda4[0](S) 241095104 blocks # mdadm --detail /dev/md_d0 mdadm: md device /dev/md_d0 does not appear to be active. Question is, how to make the device active again (using mdmadm, I presume)? (Other times it's alright (active) after boot, and I can mount it manually without problems. But it still won't mount automatically even though I have it in /etc/fstab: /dev/md_d0 /opt ext4 defaults 0 0 So a bonus question: what should I do to make the RAID device automatically mount at /opt at boot time?) This is an Ubuntu 9.10 workstation. Background info about my RAID setup in this question. Edit: My /etc/mdadm/mdadm.conf looks like this. I've never touched this file, at least by hand. # by default, scan all partitions (/proc/partitions) for MD superblocks. # alternatively, specify devices to scan, using wildcards if desired. DEVICE partitions # auto-create devices with Debian standard permissions CREATE owner=root group=disk mode=0660 auto=yes # automatically tag new arrays as belonging to the local system HOMEHOST <system> # instruct the monitoring daemon where to send mail alerts MAILADDR <my mail address> # definitions of existing MD arrays # This file was auto-generated on Wed, 27 Jan 2010 17:14:36 +0200 In /proc/partitions the last entry is md_d0 at least now, after reboot, when the device happens to be active again. (I'm not sure if it would be the same when it's inactive.) Resolution: as Jimmy Hedman suggested, I took the output of mdadm --examine --scan: ARRAY /dev/md0 level=raid1 num-devices=2 UUID=de8fbd92[...] and added it in /etc/mdadm/mdadm.conf, which seems to have fixed the main problem. After changing /etc/fstab to use /dev/md0 again (instead of /dev/md_d0), the RAID device also gets automatically mounted!

• CNAME to another domain fails on some office networks, why?

  - by crashalpha

  Our domain "aspenfasteners.com" is hosted by Volusion. We have CNAME records "find" and "search" which point to site indexing accounts on www.picosearch.com. These addresses fail on SOME private office networks which have their own DNS. We suspect the problem comes from Volusion's own name servers, n2.volusion.com and n3.volusion.com. Volusion support on problems this technical is non-existant. We have tried an NSLOOKUP on find.aspenfasteners.com with level 2 debugging info, and we got the results below. Is it possible that the local DNS is recursing to Volusion's name servers, and that while Volusion DOES return the canonical name, they do NOT resolve the address? Can anybody with expertise in this sort of stuff PLEASE look at the NSLOOKUP below and tell me if we are right, because Volusion is giving me absolutely NO support on this topic. I need proof of where the problem lies. Thanks VERY much!

• Server 2008/Windows 7/Samba Unspecified error 80004005

  - by ancillary

  I have a Samba share on a LAN with 2008 PDC/DNS. Smb authenticates with AD and I have several Win7 Machines that can connect fine. I recently added a couple of new computers to the LAN which were imaged the same way (same software, etc.; different hardware so different drivers) as the other machines and they have the same policies set. I can not get the new machines to connect to the samba share no matter what. I am always met with either Unspecified Error 0x80004005 or Network Path not found. I've turned off the firewall; set LANMAN auth to respond to NTLM only/send LM & NTLM responses/use NTLM session security if negotiated in Local Sec Policy SEcurity Options; tried both ip and hostname to connect. SMB log shows that authentication succeeds; but then connection is immediately killed by the client. tcpdump shows nothing remarkable except that when trying to connect from the client via hostname there is an unknown packet type error: ack 201 win 255 NBT Session Packet: Unknown packet type 0xABData: (41 bytes) Here's a couple of lines from that error: 11:18:37.964991 IP 001-client.domain.local.49372 > smb.domain.local.netbios-ssn: P 1670:2146(476) ack 201 win 255 NBT Session Packet: Unknown packet type 0xABData: (41 bytes) [000] AA 46 96 FA D5 99 33 75 0C C4 20 CE 26 42 F3 61 \252F\226\372\325\2313u \014\304 \316&B\363a [010] F0 8C FB 65 18 17 40 A5 DB 42 BB 94 37 53 92 EC \360\214\373e\030\027@\245 \333B\273\2247S\222\354 [020] 55 98 7F C4 AE 3D 6B 10 C4 U\230\177\304\256=k\020 \304 11:18:37.964998 IP smb.domain.local.netbios-ssn > 001-client.domain.local.49372: . ack 2146 win 100 Here's smb.conf just in case (though don't see how if other machines are working fine): [global] workgroup = MYDOMAIN realm = MYDOMAIN.LOCAL server string = domain|smb share interfaces = eth1 security = ADS password server = 192.168.1.3 log level = 2 log file = /var/log/samba/%m.log smb ports = 139 strict locking = no load printers = No local master = No domain master = No wins server = 192.168.1.3 wins support = Yes idmap uid = 500-10000000 idmap gid = 500-10000000 winbind separator = + winbind enum users = Yes winbind enum groups = Yes winbind use default domain = Yes [samba-share1] comment = SMB Share path = /home/share/smb/ valid users = @"MYDOMAIN+Domain Users" admin users = @"MYDOMAIN+Domain Admins" guest ok = no read only = No create mask = 0765 force directory mode = 0777 Any ideas what else I could try or look for?

• JNDI Datasource definition in Tomcat 6.0

  - by romaintaz

  Hi all, I want to define a DataSource to an Oracle database on my Tomcat 6.0. So, in conf/server.xml (yes, I know that this DataSource will be available for all the webapps in Tomcat, but it's not a problem here), I've set this Resource: <GlobalNamingResources> <Resource name="hibernate/HibernateDS" auth="Container" type="javax.sql.DataSource" url="jdbc:oracle:thin:@myserver:1542:foo" username="foo" password="bar" driverClassName="oracle.jdbc.OracleDriver" maxActive="50" maxIdle="10" validationQuery="select 1 from dual"/> Then, in the web.xml of my application, I set a resource-ref element: <resource-ref> <description>Hibernate Datasource</description> <res-ref-name>hibernate/HibernateDS</res-ref-name> <res-type>javax.sql.DataSource</res-type> <res-auth>Container</res-auth> </resource-ref> Finally, as Hibernate is used to manage the database connection, I have a webapps/mywebapp/WEB-INF/classes/hibernate.cfg.xml that creates a session-factory using the JNDI DataSource: <hibernate-configuration> <session-factory> <property name="connection.datasource">java:comp/env/hibernate/HibernateDS</property> ... However, when I start my Tomcat server, I get an error that says it could not create the INFO [net.sf.hibernate.util.NamingHelper] JNDI InitialContext properties:{} INFO [net.sf.hibernate.connection.DatasourceConnectionProvider] Using datasource: java:comp/env/hibernate/HibernateDS INFO [net.sf.hibernate.transaction.TransactionFactoryFactory] Transaction strategy: net.sf.hibernate.transaction.JDBCTransactionFactory INFO [net.sf.hibernate.transaction.TransactionManagerLookupFactory] No TransactionManagerLookup configured (in JTA environment, use of process level read-write cache is not recommended) WARN [net.sf.hibernate.cfg.SettingsFactory] Could not obtain connection metadata org.apache.tomcat.dbcp.dbcp.SQLNestedException: Cannot create JDBC driver of class '' for connect URL 'null' at org.apache.tomcat.dbcp.dbcp.BasicDataSource.createDataSource(BasicDataSource.java:1150) at org.apache.tomcat.dbcp.dbcp.BasicDataSource.getConnection(BasicDataSource.java:880) at net.sf.hibernate.connection.DatasourceConnectionProvider.getConnection(DatasourceConnectionProvider.java:59) at net.sf.hibernate.cfg.SettingsFactory.buildSettings(SettingsFactory.java:84) at net.sf.hibernate.cfg.Configuration.buildSettings(Configuration.java:1172) ...

• OS X server large scale storage and backup

  - by user135217

  I really hope this question doesn't come across as trolling or asking for buying advice. It's not intended. I've just started working for a small ad agency (40 employees). I actually quit being a system administrator a few years ago (too stressful!), but the company we're currently outsourcing our IT stuff to is doing such a bad job that I've felt compelled to get involved and do what I can to improve things. At the moment, all the company's data is stored on an 8TB external firewire drive attached to a Mac Mini running OS X Server 10.6, which provides filesharing (using AFP) for the whole company. There is a single backup drive, which is actually a caddy containing two 3TB hard drives arranged in RAID 0 (arrggghhhh!), which someone brings in as and when and copies over all the data using Carbon Copy Cloner. That's the entirety of the infrastructure, and the whole backup and restore strategy. I've been having sleepless nights. I've just started augmenting the backup process with FreeBSD, ZFS, sparse bundles and snapshot sends to get everything offsite. I think this is a workable behind the scenes solution, but for people's day to day use I'm struggling. Given the quantity and importance of the data, I think we should really be looking towards enterprise level storage solutions, high availability and so on, but the whole company is all Mac all the time, and I cannot find equipment that will do what we need. No more Xserve; no rack storage; no large scale storage at all apart from that Pegasus R6 that doesn't seem all that great; the Mac Pro has fibre channel, but it's not a real server and it's ludicrously expensive; Xsan looks like it's on the way out; things like heartbeatd and failoverd have apparently been removed from Lion Server; the new Mac Mini only has thunderbolt which severely limits our choices; the list goes on and on. I'm really, really not trying to troll here. I love Macs, but I just genuinely don't know where I'm supposed to look for server stuff. I have considered Linux or FreeBSD and netatalk for serving files with all the server-y goodness those OSes bring, but some the things I've read make me wonder if it's really the way to go. Also, in my own (admittedly quite cursory) experiments with it, I've struggled to get decent transfer speeds. I guess there's also the possibility of switching everyone off AFP and making them use SMB or NFS, but I understand that this can cause big problems with resource forks and file locks. I figure there must be plenty of all Mac companies out there. If you're the sysadmin at one, what do you use? Any suggestions very gratefully received.
