• Query returning an ascending group number

  - by Dougman

  I have a query like below that has groups (COL1) and that group's values (COL2). select col1, col2 from (select 'A' col1, 1 col2 from dual union all select 'A' col1, 2 col2 from dual union all select 'B' col1, 1 col2 from dual union all select 'B' col1, 2 col2 from dual union all select 'C' col1, 1 col2 from dual union all select 'C' col1, 2 col2 from dual ) order by col1, col2; The output of this query looks like: COL1 COL2 ---- ---- A 1 A 2 B 1 B 2 C 1 C 2 What I need is a query that will return an ordered number increasing for each different group (COL1). It seems like there would be a simple way to accomplish this (maybe with analytics) but for some reason it is escaping me. GRPNUM COL1 COL2 ------ ---- ---- 1 A 1 1 A 2 2 B 1 2 B 2 3 C 1 3 C 2 I am running Oracle 10gR2.

• MySQL, PHP, How Many in GROUP

  - by 0Neji

  I'm trying to create a table which outputs a list of users and how many times they've logged in. A new row in the table is created every time that someone logs in so there is multiple rows for one user. Now, I'm trying using the following statement to pull the data out: SELECT * FROM logins GROUP BY user ORDER BY timestamp DESC Which is working fine but now there is a column in my HTML table which should show how many times the user has logged in. How do I go about counting the amount of rows in each group?

• Upgraded AGPM Server cannot connect to relocated archive

  - by thommck

  We were using the Advanced Group Policy Management (AGPM) v3.0 on out Windows Server 2008 DC. It kept the archive on the C: drive. When we upgraded to AGPM v4 we relocated the archive to the D: drive. Now when we try to look at a GPO's hisory in GPMC we get the following error Failed to connect to the AGPM Server. The following error occurred: The server was unable to process the request due to an internal error. For more information about the error, either turn on IncludeExceptionDetailInFaults (either from ServiceBehaviorAttribute or from the configuration behavior) on the server in order to send the exception information back to the client, or turn on tracing as per the Microsoft .NET Framework 3.0 SDK documentation and inspect the server trace logs. System.ServiceModel.FaultException (80131501) You are able to click Retry or Cancel. Retry brings up the same error and Cancel takes you back to GPMC and the History tab displays "Archive not found". I installed the client on a Windows 7 computer (which is a n unsupported set up) and it could read the server archive without any issues. I followed the TechNet article "Move the AGPM Server and the Archive" but that didn't make a difference How can I tell the server where the archive is?

• signed applet automatically running as insecure

  - by Terje Dahl

  My application is deployed as a self-signed applet to several thousand users at more than 50 schools across the country (in Norway). The user is presented with the standard Java security warning asking if they will accept the signature. When they do, the applet runs perfectly. However, about half a year ago a group of 7 school, all under a common IT department, stopped getting the security warning. In stead the applet loads and starts running in untrusted mode, without first giving the user an option to accept or reject the signature. The problem is on Windows machines, and only when the machine is connected to the schools network. If they take the same machine home with them, the program functions as it should, with security warnings and everything. I know little about Window systems in general, but I would think it would be some sort of policy-file or something that is loaded when a machine hooks up to/through the schools network. Furthermore, the problem only started occurring in these 7 schools after changes made after a security breach they had a while back. The IT department is stumped. I am stumped. Any thoughts, comments, suggestions?

• Splitting Servers into Two Groups

  - by Matt Hanson

  At our organization, we're looking at implementing some sort of informal internal policy for server maintenance. What we're looking at doing is completing maintenance on our entire server pool every two months; each month we'll do half of the servers. What I'm trying to figure out is some way to split the servers into the two groups. Our naming convention isn't much to be desired (but getting better) so by name or number doesn't really work. I can easily take a list of all the servers and split them in two, but with new servers are being added constantly, and old ones retired, that list would be a headache to maintain. I'd like to look at any given server and know if it should have its maintenance done this month or next. For example, it would be nice to look at the serial number. If it started with an even number, then it gets maintenance done on even months and vice-versa. This example won't work though as a little over half of the servers are virtual. Any ideas?

• Where in the stack is Software Restriction Policies implemented?

  - by Knox

  I am a big fan of Software Restriction Policies for Microsoft Windows and was recently updating our settings for this. I became curious as to where Microsoft implemented this technology in the stack. I can imagine a very naive implementation being in Windows Explorer where when you double click on an exe or other blocked file type, that Explorer would check against the policy. I call this naive because obviously this wouldn't protect against someone typing something in a CMD window. Or worse, Adobe Reader running an external application. On the other hand, I can imagine that software restriction policies could be implemented deep in the stack almost at the metal. In this case, the low level loader would load into memory the questionable file, but mark the memory in the memory manager as non-executable data. I'm pretty sure that Microsoft did not do the most naive implementation, because if I block Java using a path block, Internet Explorer will crash if it attempts to load Java. Which is what I want. But I'm not sure how deep in the stack it's implemented and any insight would be appreciated.

• Cisco ASA 5510 Time of Day Based Policing

  - by minamhere

  I have a Cisco ASA 5510 setup at a boarding school. I determined that many (most?) of the students were downloading files, watching movies, etc, during the day and this was causing the academic side of our network to suffer. The students should not even be in their rooms during the day, so I configured the ASA to police their network segment and limit their outbound bandwidth. This resolved all of our academic issues, and everyone was happy. Except the resident students. I have been asked to change/remove the policing policy at the end of the day, to allow the residents access to the unused bandwidth at night. There's no reason to let bandwidth sit unused at night just because it would be abused during the day. Is there a way to setup Time of Day based Policies on the ASA? Ideally I'd like to be able to open up the network at night and all day during weekends. If I can't set Time based policies, is is possible to schedule the ASA to load a set of commands at a specific time? I suppose I could just setup a scheduled task on one of our servers to log in and make the changes with a simple script, but this seems like a hack, and I'm hoping there is a better or more standard way to accomplish this. Thanks. Edit: If there is a totally different solution that would accomplish a similar goal, I'd be interested in that as well. Free/Cheap would be ideal, but if a separate internet connection is my only other option, it might be worth fighting for money for hardware or software to do this better or more efficiently.

• Users and Groups management on 7 Home Premium

  - by AviD

  Recently upgraded the home pc from XP pro, to Windows 7 Home Premium. I'm looking for a solution for a few things that seem to be missing from this edition... Since Local Users and Groups is blocked on Home Premium, I can't figure out how to manage groups, or even do anything even slightly advanced to users (basically, create/group/picture is it). net localgroup, net users, net etc dont seem to work - getting "system error 5". While I'm on the topic, I cant activate (what was once) "Local Security Policy"... Looking for any help, advice, or even a new direction cuz things is differ'nt on Winnows7... To clarify, I'm looking to do some of the following, which were simply back in XP-land: remote user only (i.e. no local logon) Grant special privileges for specific user grant access to e.g. C$ share for specific remote user create custom groups for users, to be able to separate privileges of say, my wife's from my kids define quite specifically what each user can do (beyond just standard users) Harden OS (hmm, i guess maybe what i'm looking for is security hardening guide for 7...?)

• How can I make WSUS less invasive for our users?

  - by Cypher

  We have WSUS pushing updates out to our user's workstations, and things are going relatively well with one annoying caveat: there seems to be an issue with a pop-up being displayed in front of some users informing them that their machine will be rebooted in 15 minutes, and they have nothing to say about it: This may be because they did not log out the prior night. Nevertheless, this is a bit too much and is very counter-productive for our users. Here is a bit about our environment: Our users are running Windows XP Pro and are part of an Active Directory Domain. WSUS is being applied via Group Policy. Here is a snapshot of the GPO that is enforcing the WSUS rules: Here is how I want WSUS to work (ideally - I'll take whatever can get me close): I want updates to automatically download and install every night. If a user is not logged in, I would like the machine to reboot. If a user is logged in, I would like their machine not to reboot, but instead wait until the next "installation period" where it can perform any other needed installations and reboot then (provided the a user account is not still logged in). If a user is to be prompted for reboot, it should only happen once per day (if possible), but every time they are prompted, they must have a way to postpone the reboot. I do not want users to be forced to restart their computer whenever the computer thinks it should happen (unless it's after an update installation and there are no logged in users). That doesn't seem productive to force a system restart in the midst of a person's workday. Is there something that I can do with the GPO that would help make WSUS less intrusive? Even if it gave the user an option to Restart Later - that would be better than what is happening now.

• Single Sign On 802.1x Wireless - saying “Connecting to <SSID>”, hangs for 10 seconds, fails with “Unable to connect to <SSID>, Logging on…”.

  - by Phaedrus

  We are implementing WiFi on Windows 7 machines in our corporate environment. Machines should be able to log into the domain by WiFi as the Machine (Pre-Logon), and as the User (Post-Logon). We have everything working correctly except for 2 things: 1) Sometimes the login scripts don't run 2) The user VLAN is sometimes different than the machine vlan, and no DHCP renew occurs after user logon. I am clear that both these problems should be fixable by using the "Single Sign On" Option under the 802.1x Wireless Vista GPO, and setting the wireless to connect immediately before user logon and also by enabling "This network uses different VLAN for authentication with machine and user credentials" If I enable these GPO settings in a lab, the computer does authenticate & gets WIFI before the user logs on, so when the login box is displayed, it says “Windows will try to connect to ”, even though it is already connected (which should be ok?). Enter the user credentials and it goes to a screen saying “Connecting to ”, hangs for 10 seconds, fails with “Unable to connect to , Logging on…”. Desktop fires up and then the user re-authenticates with no problem as himself instead of the machine, but by that point, we defeat the point of the WiFi SSO “before user logon”. Also by that point, no DHCP renew seems to occur, and the user is still stuck with the wrong IP address for the new VLAN. When the “Connecting to ” screen comes up, there’s no indication on the AP or the Radius server that anything whatsoever is happening after credentials are entered until after the domain logon. Also with this policy enabled, sometimes windows hangs on a black screen indefinitely until I disable the Wireless NIC, so something is knackered for sure. What have I missed? Suggestions are much appreciated... /P

• Email attachments sent to a group don't show up for some

  - by blsub6

  My boss sent out an email from my Exchange 2010 org and attached a PDF and a Word doc to it. He came back the next day and told me that some of the 8 or 10 people that received this email could open up the attachments no problem. The other 2 or 3 people, could not. One of these people who could not open the attachment, went so far as to call Comcast (his email service provider) and ask them where his attachments went. Comcast told this person that when they received the email, the attachment was 0 bytes in size. This may sound like more of a rant than a question but I'm genuinely concerned. Is there any possible way that something could have gone wrong on my end that sent out the email to some with the attachment and to some without?

• Plone Active Directory group filter

  - by Jason Weber

  I am currently trying to configure the Plone LDAP plugin for Active directory. Thus far all is good and I’m getting users and groups through. The usage is for Cyn.In However the problem I’m facing is thus: The users search has the ability to filter, which is great. I can use the memberOf or department filter to just grab the users I want. However all our groups simply live in one OU, which means I’m getting over 30 pages of groups of which 99% are just not necessary. Sadly I don’t have control over our AD, so can’t just shift the ones I want into their own OU. Is there any way you can think of to also filter groups based on some kind of LDAP criteria?

• The Cindy Shearin Group: New Scam Targets Renters in the Area

  - by user226089

  MONROE - Craigslist is a popular site when trying to find that perfect deal on a rental home or apartment. Experts warn some of these rental ads aren't what they seem. We decided to take a look. On our Craigslist search we found this house for rent. The problem is this home’s not for rent - it's for sale. “I think it’s a huge deal,” said Shane Wooten, the realtor for this home in Monroe. His properties have become the target of a common scam, aimed at taking your money. "It looks like they're trying to scam them out of their deposit and first months rent," adds Wooten. He says scammers copy and paste the sale ad's from legitimate realtor sites to Craigslist as rental ads. "I can usually tell when one hits craigslist because I’ll usually get 20 to 30 phone calls that day." They then pretend to be out of town on business or personal matters, and give only an email address as a point of contact. Usually they'll ask for money up front on a deal too good to miss. "You'll have a house that's supposed to rent for $950-1000 a month, and they'll have it renting for $600 a month,” says Wooten During our conversation, he shows us text messages from one scammer who says he'll mail the keys to this house if Wooten wires money for a deposit and first months rent. Jo Ann Deal of the Better Business Bureau says scammers are getting better at making themselves out to be realtors. "We’re really concerned for our real estate agents with this scam," says Deal. She says that realtors have to be more on top of their vacant homes in order to protect their businesses. So how can you tell if the house you want is really for rent? She says if the home owner lives out of the country, can't meet face to face or asks for a payment through a money wire it's probably a scam. “There are some catch-lines you watch for,” says Deal. “If the marketing is really good but there's no phone number, no physical address and they will communicate with you only by email and you can do it today, then it's probably a scam." You should always report fishy ad's to Craigslist or the BBB and never send money through a wire transfer.

• How to stop a group of systemd custom services

  - by tsingyue

  I wrote three service units, say a.service b.service and c.service. C requires and runs after b, b requires and runs after a, so when I execute "systemctl start c.service", all three of them will be launched one by one. But when I want to stop all of them, I have to execute "systemctl stop a.service b.service c.service". Is there any other way to stop all of them with less typing? I know with "Bindto=" I can use "systemctl stop a.service" to stop all of them, but what if I got c Bindto a and b, while a and b have no required relationship to each other?

• Grant a user access to directories shared by root (mod: 770)

  - by Paul Dinham

  I want to grant a user (username: paul) access to all directories shared by root with mod 770. I do it this way: groups root (here comes a list of groups in which root user is) usermod -a -G group1 paul usermod -a -G group2 paul usermod -a -G group3 paul ... All the 'group1', 'group2', 'group3' are seen in the group list of root user. However, after adding 'paul' to all groups above, he still can not write to directories shared by root user with mod 770. Did I do it wrongly?

• Set default reminder pattern to iCal Calendar/Group

  - by elhombre

  Hi all I have in iCal some Calendars/Groups named Birthday, Exams and Holidays. Now I am wondering if I can assign a default reminder pattern to all Exams events, for example: 2 Weeks before, 1 Week before, 2 Days before. The result should be that I don't have to specify each time the reminder pattern of an event in Exams when I create a New one. NOTE: If iCal can't do this, is it maybe possible do that through an automator action etc.?

• The Koyal Group Info Mag News¦Charged building material could make the renewable grid a reality

  - by Chyler Tilton

  What if your cell phone didn’t come with a battery? Imagine, instead, if the material from which your phone was built was a battery. The promise of strong load-bearing materials that can also work as batteries represents something of a holy grail for engineers. And in a letter published online in Nano Letters last week, a team of researchers from Vanderbilt University describes what it says is a breakthrough in turning that dream into an electrocharged reality. The researchers etched nanopores into silicon layers, which were infused with a polyethylene oxide-ionic liquid composite and coated with an atomically thin layer of carbon. In doing so, they created small but strong supercapacitor battery systems, which stored electricity in a solid electrolyte, instead of using corrosive chemical liquids found in traditional batteries. These supercapacitors could store and release about 98 percent of the energy that was used to charge them, and they held onto their charges even as they were squashed and stretched at pressures up to 44 pounds per square inch. Small pieces of them were even strong enough to hang a laptop from—a big, fat Dell, no less. Although the supercapacitors resemble small charcoal wafers, they could theoretically be molded into just about any shape, including a cell phone’s casing or the chassis of a sedan. They could also be charged—and evacuated of their charge—in less time than is the case for traditional batteries. “We’ve demonstrated, for the first time, the simple proof-of-concept that this can be done,” says Cary Pint, an assistant professor in the university’s mechanical engineering department and one of the authors of the new paper. “Now we can extend this to all kinds of different materials systems to make practical composites with materials specifically tailored to a host of different types of applications. We see this as being just the tip of a very massive iceberg.” Pint says potential applications for such materials would go well beyond “neat tech gadgets,” eventually becoming a “transformational technology” in everything from rocket ships to sedans to home building materials. “These types of systems could range in size from electric powered aircraft all the way down to little tiny flying robots, where adding an extra on-board battery inhibits the potential capability of the system,” Pint says. And they could help the world shift to the intermittencies of renewable energy power grids, where powerful batteries are needed to help keep the lights on when the sun is down or when the wind is not blowing. “Using the materials that make up a home as the native platform for energy storage to complement intermittent resources could also open the door to improve the prospects for solar energy on the U.S. grid,” Pint says. “I personally believe that these types of multifunctional materials are critical to a sustainable electric grid system that integrates solar energy as a key power source.”

• Batch deletion of smaller files from group of files via unix command line

  - by artlung

  I have a large number (more than 400) of directories full of photos. What I want to do is to keep the larger sizes of these photos. Each directory has 31 to 66 files in it. Each directory has thumbnails, and larger versions, plus a file called example.jpg I dispatched the example.jpg file easily with: rm */example.jpg I initially thought that it would be easy to delete the thumbnails, but the problem is they are not consistently named. The typical pattern was photo1.jpg and photo1s.jpg. I did rm */photo*s.jpg but it ended up some of the files named photoXs.jpg were actually larger and not smaller. Argh. So what I want to do is scan each directory for filesize and delete (or move) the thumbnails. I initially thought I'd just ls -R every file and extract the size of each file and save those under a threshold. The problem? In one directory the large will be 1.1 MB and the thumb is 200k. In another the large is 200k and the small 30k. Even worse, the files really are mostly named photo1.jpg - so simply putting them all in the same folder, sorting by size, and deleting in groups would not work without renaming already, and if it's possible I'd prefer to keep them in their folders. I was almost resolved to just doing this all manually, but then thought I'd ask here. How would you do this task?

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

  - by graf_ignotiev

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

• is there a way to group desktop icons on the task bar

  - by Memor-X

  i have a folder on the desktop which has a bunch of programs i use frequently, i can't pin all these programs to the taskbar themselves as there are too many for the screen width that it'll just make the taskbar scrollable i am wondering if i can do one of the following pin the icons to the taskbar under 1 icon pin the folder to the taskbar separately to the Windows Explorer button which when there are no folders open will open up the libraries and if there are folders it'll show me the folders open, this way if i have 5 folders open and my frequently used programs folder i can just click on the frequently used programs folder icon on the taskbar and be given that folder only i'm trying to reduce the number of clicks, scrolling or scanning across the task bar i need to do in order to find a program

• directory services group query changing randomly

  - by yamspog

  I am receiving an unusual behaviour in my asp.net application. I have code that uses Directory Services to find the AD groups for a given, authenticated user. The code goes something like ... string username = "user"; string domain = "LDAP://DC=domain,DC=com"; DirectorySearcher search = new DirectorySearcher(domain); search.Filter = "(SAMAccountName=" + username + ")"; And then I query and get the list of groups for the given user. The problem is that the code was receiving the list of groups as a list of strings. With our latest release of the software, we are starting to receive the list of groups as a byte[]. The system will return string, suddenly return byte[] and then with a reboot it returns string again. Anyone have any ideas? code sample: DirectoryEntry dirEntry = new DirectoryEntry("LDAP://" + ldapSearchBase); DirectorySearcher userSearcher = new DirectorySearcher(dirEntry) { SearchScope = SearchScope.Subtree, CacheResults = false, Filter = ("(" + txtLdapSearchNameFilter.Text + "=" + userName + ")") }; userResult = userSearcher.FindOne(); ResultPropertyValueCollection valCol = userResult.Properties["memberOf"]; foreach (object val in valCol) { if (val is string) { distName = val.ToString(); } else { distName = enc.GetString((Byte[])val); } }

• Is there a way to use something similar to a capture group for apache2 server name

  - by Zipper

  I have a server that sits behind an AWS load balancer. The LB can't do automatic redirect from HTTP to HTTPs, and the LB is doing my SSL. So I need to setup apache on my servers to redirect any request on port 80 to https://FOOBAR m where FOOBAR is the domain that came in. I haven't been able to find a way of doing that so far. I'm an apache newb though. What I'm trying to do is something similar to this. I'll use regex as an example <VirtualHost *:80> ServerName (.*) Redirect / https://\1 </VirtualHost> If there's a better way to do this, please let me know. EDIT: Sorry I should have explained why this is happening. I actually have a tomcat server running my app on port 8080, and the LB points to that. From what I can tell so far my requests come in on http (which is expected), but when my app server sends redirects (for login purposes) it tries to redirect to http, instead of https. I haven't had a chance to fully investigate this, but I wanted to work around it for now by point the LB to point to the apache server, and have any port 80 requests redirect to 443. EDIT2: The other reason I'm interested in doing this, is that since the LB can't do the redirect, I need to have another redirect mechanism in place to tell the browser to go to https://FOOBAR
