  • Identifying if a user is in the local administrators group

    - by Adam Driscoll
    My Problem I'm using PInvoked Windows API functions to verify if a user is part of the local administrators group. I'm utilizing GetCurrentProcess, OpenProcessToken, GetTokenInformationand LookupAccountSid to verify if the user is a local admin. GetTokenInformation returns a TOKEN_GROUPS struct with an array of SID_AND_ATTRIBUTES structs. I iterate over the collection and compare the user names returned by LookupAccountSid. My problem is that, locally (or more generally on our in-house domain), this works as expected. The builtin\Administrators is located within the group membership of the current process token and my method returns true. On another domain of another developer the function returns false. The LookupAccountSid functions properly for the first 2 iterations of the TOKEN_GROUPS struct, returning None and Everyone, and then craps out complaining that "A Parameter is incorrect." What would cause only two groups to work correctly? The TOKEN_GROUPS struct indicates that there are 14 groups. I'm assuming it's the SID that is invalid. Everything that I have PInvoked I have taken from an example on the PInvoke website. The only difference is that with the LookupAccountSid I have changed the Sid parameter from a byte[] to a IntPtr because SID_AND_ATTRIBUTESis also defined with an IntPtr. Is this ok since LookupAccountSid is defined with a PSID? LookupAccountSid PInvoke [DllImport("advapi32.dll", CharSet = CharSet.Auto, SetLastError = true)] static extern bool LookupAccountSid( string lpSystemName, IntPtr Sid, StringBuilder lpName, ref uint cchName, StringBuilder ReferencedDomainName, ref uint cchReferencedDomainName, out SID_NAME_USE peUse); Where the code falls over for (int i = 0; i < usize; i++) { accountCount = 0; domainCount = 0; //Get Sizes LookupAccountSid(null, tokenGroups.Groups[i].SID, null, ref accountCount, null, ref domainCount, out snu); accountName2.EnsureCapacity((int) accountCount); domainName.EnsureCapacity((int) domainCount); if (!LookupAccountSid(null, tokenGroups.Groups[i].SID, accountName2, ref accountCount, domainName, ref domainCount, out snu)) { //Finds its way here after 2 iterations //But only in a different developers domain var error = Marshal.GetLastWin32Error(); _log.InfoFormat("Failed to look up SID's account name. {0}", new Win32Exception(error).Message); continue; } If more code is needed let me know. Any help would be greatly appreciated.

Actually, what I'm trying to do is to render several tables, one for each different date, with data inside. I have no ideia. How do I do that? Thx in advance

    I have a db with thousands of domains and data. I want to list only 100 rows of each domain. i can't use LIMIT 100 cause that only limits 100 records but I want dom1 to list 100 dom2 to list 100 dom3 to list 100 all in one query. This is what I have so far. SELECT domain COUNT(Key) AS DomCount FROM table_domain GROUP BY user,location ORDER BY domain,DomCount DESC Could I use a CASE?

  • Install a KVM guest with LVM partitioning on an LVM partitioned host using virt-install fails, volume group already exists

    - by Rilik84
    our setup consists of a ubuntu 10.04 kvm host server with LVM, on top of which we install the ubuntu 10.04 virtual machines via virt-install and preseed. Each VM has a dedicated logical volume which we pass to virt-install via the "--disk path=/dev/sysvg/vm-name" parameter. The virtual machines themselves are using LVM as well. Virt-install seems to have a few issues with this setup. Say we want to install two virtual machines in parallel. The first vm installs correctly while the second halts during the partitioning, complaining with this error: "volume group name already in use". I tried removing the logical volumes, recreated them, rebooted the kvm host to clear any leftovers but the issue perists. The preseed is telling the vms to create a volume group named "sysvg", which is the same name used by the volume group of the kvm host. Considering this I did another test: I got rid of the preseed part taking care of the partitioning/lvm creation and started the creation of two vms in parallel. If, when prompted, I instruct the vms' installer to do a guided partitioning of the disk with LVM, it will still fail giving this different error on both the vms: Physical Volume /dev/sda5 is already in volume group sysvg. As I wrote, sysvg is the volume group used by the KVM host. So I thought the name clashing was the issue. By removing the preseed part I skipped the volume group naming. I can't understand how the virtual machines would be aware of the presence of that volume group since they're supposed to be isolated from it, especially after I removed and recreated the logical volumes dedicated to them. That detail should not be exposed at all to them! Thanks for the help. I'm clueless.

  • How to select the first property with unknown name from JSON and how to select first item from array

    - by Oscar Godson
    I actually have two questions, both are probably simple, but for some odd reason I cant figure it out... I've worked with JSON 100s of times before too! but here is the JSON in question: {"69256":{"streaminfo":{"stream_ID":"1025","sourceowner_ID":"2","sourceowner_avatar":"http:\/\/content.nozzlmedia.com\/images\/sourceowner_avatar2.jpg","sourceownertype_ID":"1","stream_name":"Twitter","streamtype":"Social media","appsarray":[]},"item":{"headline":"Charboy","main_image":"http:\/\/content.nozzlmedia.com\/images\/author_avatar173212.jpg","summary":"ate a tomato and avocado for dinner...","nozzl_captured":"2010-05-12 23:02:12","geoarray":[{"state":"OR","county":"Multnomah","city":"Portland","neighborhood":"Downtown","zip":"97205","street":"462 SW 11th Ave","latitude":"45.5219","longitude":"-122.682"}],"full_content":"ate a tomato and avocado for dinner tonight. such tasty foods. just enjoyable.","body_text":"ate a tomato and avocado for dinner tonight. such tasty foods. just enjoyable.","author_name":"Charboy","author_avatar":"http:\/\/content.nozzlmedia.com\/images\/author_avatar173212.jpg","fulltext_url":"http:\/\/twitter.com\/charboy\/statuses\/13889868936","leftovers":{"twitter_id":"tag:search.twitter.com,2005:13889868936","date":"2010-05-13T02:59:59Z","location":"iPhone: 45.521866,-122.682262"},"wordarray":{"0":"ate","1":"tomato","2":"avocado","3":"dinner","4":"tonight","5":"tasty","6":"foods","7":"just","8":"enjoyable","9":"Charboy","11":"Twitter","13":"state:OR","14":"county:Multnomah, OR","15":"city:Portland, OR","16":"neighborhood:Downtown","17":"zip:97205"}}}} Question 1: How do I loop through each item (69256) when the number is random? e.g. item 1 is 123, item2 is 646? Like, for example, a normal JSON feed would have something like: {'item':{'blah':'lorem'},'item':{'blah':'ipsum'}} the JS would be like console.log(item.blah) to return lorem then ipsum in a loop How do I do it when i dont know the first item of the object? Question 2: How do I select items from the geoarray object? I tried: json.test.item.geoarray.latitude and json.test.item.geoarray['latitude']

  • How can I use GPRename's regex feature to reinsert the matched-group into the 'replace'?

    - by David Thomas
    I've been using GPRename to batch-rename files; this is rather more efficient than individually correcting each file, but still seems to be less efficient than it might be, primarily because either I don't understand the regex syntax used, or because the regex implementation is incomplete1 Given a list of files of the following syntax: (01) - title of file1.avi (02) - title of file2.avi (03) - title of file3.avi I attempted to use the 'replace' (with the regex option selected, the case-sensitive option deselected): (\(\d{2}\)) The preview then shows (given that I've specified no 'replace with' option as yet): title of file1.avi title of file2.avi title of file3.avi Which is great, clearly the regex is identifying the correct group (the (01)). Now, what I was hoping to do (using the JavaScript syntax) in the 'replace with' option is use: $1 (I also tried using '$1', \1 and '\1') This was just to check that I could access the matched group, and it seems I can't, the matched group is, as I suppose might be expected, replaced with the literal replacement string. So, my question: is it possible to match a particular group of characters, in this case the numbers within the brackets, and then insert those into the replacement string? Therefore: (01) title of file1.avi (02) title of file2.avi (03) title of file3.avi Becomes: 01 title of file1.avi 02 title of file2.avi 03 title of file3.avi I absolutely suspect the former, personally.
