• weird POST request in IIS logs

  - by MIrrorMirror

  I noticed weird log entries (unless there's something i don't understand) in my IIS (7.5) logs. it's an online dictionary with requests ( user friendly url rewriting ) and most of them are GET. However I noticed weird POST requests which are taking place by a person who is trying to crawl our content ( tens of thousands of such requests ) 2013-11-09 20:39:27 GET /dict/mylang/word1 - y.y.y.y Mozilla/5.0+(compatible;+Googlebot/2.1;++http://www.google.com/bot.html) - 200 296 2013-11-09 20:39:29 GET /dict/mylang/word2 - z.z.z.z Mozilla/5.0+(iPhone;+CPU+iPhone+OS+6_0+like+Mac+OS+X)+AppleWebKit/536.26+(KHTML,+like+Gecko)+Version/6.0+Mobile/10A5376e+Safari/8536.25+(compatible;+Googlebot-Mobile/2.1;++http://www.google.com/bot.html) - 200 468 2013-11-09 20:39:29 POST /dict/mylang/word3 - x.x.x.x - - 200 2593 The two first requests are legal. Now for the third request, I don't think I have allowed cross domain POST. if that what the third log line means. all those POST requests take that much time for unknown reasons to me. I would like to know how are those POST requests possible and how can I stop them. p.s. I have masked the IPs on purpose. any help would be appreciated! thank you in advance.

• Excel data into PowerPoint slides

  - by nqw1

  I have already found some helpful sites but I'm still unable to do what I want. My Excel file contains few columns and multiple rows. All the data from one row would be in one slide but data from different cells in that one row should go to a specific elements in PP slide. At first, is it possible to export data from an Excel cell into a specific text box in PP? For example, I would like to have all data from the first column of each row go to a Text box 1. Let's say I have 100 rows so I would have 100 slides and each slide would have Text bow 1 with correct data. Text box of slide 66 would have data from the first column of row 66. Then all data from the second column of each row would go to a text bow 2 and so on. I tried to do some macros with bad success. I also tried to use Word outlines and export them into PP (New slide - Slides from Outline) but there seems to be a bug since I got 250 pages of gibberish. I had only two paragraphs and both had one word. First paragraph used Heading 1 style and second paragraph used Normal style. Sites what I have found, use VB and/or some other programming language to create slides from Excel sheets. I have tried to add those VB codes into my macros but none of them hasn't worked so far. Probably I just don't know how to use them correctly :) Here's some helpful sites: VBA: Create PowerPoint Slide for Each Row in Excel Workbook Creating a Presentation Report Based on Data Question in Stackoverflow I use Office 2011 on Mac. Any help would be appreciated!

• Two large, linked Excel files take 30 minutes to save, except in VMWare environment

  - by Gerald L

  I support some tax consultants who love to use Excel when they should probably be using Access. Anyway, they have created two Excel files, A and B. File B has cells linked to file A. File A is 27 MB and file B is 16 MB. One worksheet has roughly 1 million rows and there is another worksheet doing a whole bunch of SUMIF on the 1 million rows. Not the best idea, but whatever. Both Excel files open and recalculate within a reasonable amount of time (1-2 minutes). For a files that large, this is acceptable. Here is the problem: Once you change a cell, and save the file B, it takes a solid 30 minutes to save the file, and the processors are going full speed. I've tried this on 6 different machines, all running Windows XP SP3 with Office 2007 SP2 and all patches. The specs vary from one machine with 512 MB or RAM to a machine with 4 GB of RAM and quad processors. Same result every time. Here is the clincher: If I do this same save operation on a VMWare virtual machine, the file gets saved in 1 minute. I've tried this with my ESX servers at the office, my Mac Fusion at home, and VMWare workstation at the office. It does not matter how much RAM the virtual machine has... it saves in about 1 minute every time. Does anybody have any idea why this is happening and how to fix?

• SQL 2008 Replication corrupt data problem

  - by Jonathan K

  We took a SQL 2000 database. Took a lightspeed backup. Restored on SQL 2008 active/passive cluster. Then setup replication to replicate the data back to SQL 2000. So 2008 is the publisher/distributor, and 2000 is doing a pull subscription. Everything works well, execpt we occassionally get corrupt data in varchar/text fields on the subscriber. So for example we have a table with 4500 records. When we run this statement: update MedstaffProvider set Notes = 'Cell Phone: 360.123.4567 Answering Service: 360.123.9876' where LastName = 'smith' The record in the 2008 database is updated as expected. But in the subsriber datbase we'll get gibberish in the notes field: óPÌ[1] T $Oé[1] ð²ñ. K Here's what we know: This is repeatable, meaning we can run that same query all day long and get the same gibberish. If you alter update statement slightly the data gets replicated just fine. The collation on both databases is the same. So far we've only detected the problem with text/varchar fields. (The notes field above is text). Only one or two records in a table are impacted. The table structure looks identical in both 2000/2008. We haven't made any changes. We have found one solution that fixes the problem. Basically if we recreate the table in 2008 (say as MedStaffProvider2) and then insert all the data. Drop the original table. Rename the table to it's original name. Setup replication again. And run the exact same update statement it works as expected. Does anyone have any idea what might be happening here? Or are there any other techniques we can use to troubleshoot this? I've found a solution for this, but would really like to undertsand why this is happening.

• VPN Error 691 but server says authenticated on server

  - by Andy

  Hello all, I have a problem with a vpn connection on Windows XP SP3 that appears to be related to an account (maybe privilleges or an option that I have missed). When connecting using my account, which is a domain administrator account it will connect to through the vpn fine. However, using an account created for another person they receive Error 691: Username or Password is not valid for this domain. On the domain controller (windows 2003) I see a logon successful message: User DOMAIN\user was granted access. Fully-Qualified-User-Name = int.company.net.au/People/Management/User NAS-IP-Address = 10.30.0.3 NAS-Identifier = not present Client-Friendly-Name = MelbourneCore Client-IP-Address = Router-ip Calling-Station-Identifier = not present NAS-Port-Type = Virtual NAS-Port = 77 Proxy-Policy-Name = Use Windows authentication for all users Authentication-Provider = Windows Authentication-Server = undetermined Policy-Name = Remote VPN Access Authentication-Type = MS-CHAPv1 EAP-Type = Does anyone have any ideas as to where else I should look for finding a solution? If i use the wrong password it gives a logon failure error in the event viewer. Also removing them from the remote access group gives a logon failure error. Nothing appears in the event viewer on the local machine. In the past all that is required is to add them into our Remote Access Users group. Any help?

• Installing Silverstripe on 000webhost.com (free web host)

  - by benwad

  Hi I'm trying to learn how to work Silverstripe so I extracted the tar file to my free hosting account. I then went on install.php and edited the permissions to meet the requirements set out in install.php but I still get two warnings from the 'webserver configuration' section: I can't tell what webserver you are running. Without Apache I can't tell if mod_rewrite is enabled. I can't tell whether mod_rewrite is running. You may need to configure a rewriting rule yourself. I looked in phpinfo() and mod_rewrite appears to be installed. I contacted the web host and they said it was to do with virtual directory paths, and I should add 'RewriteBase /' to the top of my .htaccess file in the public_html directory. However I did this and still had the same problem. The install.php script says that I can install it even with these warnings but when I press 'install' it just refreshes the install.php page. It doesn't even overwrite the .htaccess file. 000webhost.com says they have successfully installed Silverstripe on their user accounts without much configuration but I can't seem to find out how. EDIT: I managed to get to the next page but now there is another warning which is stopping it installing: Friendly URLs are not working. This is most likely because mod_rewrite isn't configuredcorrectly on your site. Please check the following things in your Apache configuration; you may need to get your web host or server administrator to do this for you: * mod_rewrite is enabled * AllowOverride All is set for your directory I also get this error message from the server: Warning: unlink(mysite/_config.php) [function.unlink]: Permission denied in /home/a2716553/public_html/install.php on line 701

• Setup for a live (low-latency) audio video broadcast over Wi-Fi?

  - by Majal Mirasol

  The Upgrade We are capturing audio (from mixer) and video (from a camera) from a main auditorium and passing it to separate rooms within the building. We used to have done this via manual audio/video cables and wires. We wanted to "upgrade" the system and wirelessly broadcast the stream via Wi-Fi. The Problem In our current setup (Wirecast running on A10 on a Wireless-N network), we have the problem of delay. Our streams are delayed from a minute up to five minutes on the clients (laptop/iPad/Android). This had not been a problem from the previous wired connections. Since the wireless network is local, we thought that a delay of less than a second should be achievable. Our Question And so it goes. Anybody there who has any experience for a setup that has both low latency and at the same time user-friendly to clients streaming in the program? Any recommendations would be highly appreciated. (Our current setup in on Windows 7, but setup on a dedicated Linux box is preferred, if achievable.)

• Monitoring / metric collection for system collectives that change a lot in time (a.k.a. cloud)

  - by Florin Andrei

  When your server fleet doesn't change a lot in time, like when you're using bare-metal hosting, classic monitoring and metric collection solutions (Nagios, Munin) work well. But if the number of systems varies a lot in time, and may in fact vary rapidly, classic software is more difficult to setup and use. E.g., trying to make Nagios (monitoring) keep up with a rapidly evolving cloud infrastructure can be cumbersome. Same for Munin (metric collection). It's not just the configuration, but the way the information is conveyed to the user, or displayed, is inadequate for the cloud. What are some possible alternatives that work well with the cloud? The goals are to collect and display metrics (analog to Munin), and generate alerts when certain metrics go out of bounds or when certain services are unavailable (analog to Nagios), and do everything in a cloud-friendly manner. Some cloud providers offer monitoring / metric collection as services, but not always, and if you use more than one provider you don't want to become too dependent of just one vendor. So provider-independent solutions are required. EDIT: I am asking this question in a general fashion - not limited to any given cloud infrastructure (like OpenStack), but in the general case of using arbitrary cloud providers.

• Liferay - Verify each node in a cluster

  - by Schrute

  In this example, I have two clustered instances of Liferay using bundled Tomcat running, using cluster link and shared documents. Let's say the name of the public community is fubar and friendy URL used is fubar.lipsum.com. Let's say the ports listening on each server is 8080. If I go to both server1:8080 or server2:8080 I will get the default page for Liferay. How can I test fubar.lipsum.com on each node by using the backend server, so I can verify each server? If I test it, it just goes to the load balancer, I wish there was a way to append to the backend connection to bring it up. I can add the friendly URL to my local machines hosts file and this seems to kinda work, but then once something is called in the application, it tries to go out again from the backend server and then uses SSL and then we have problems. I think I may be able to do port forwarding, but this seems like a basic thing we should be able to do and what I've found so far in the admin docs has not helped. Using the option to print the server name in the page details isn't an option either.

• Ubuntu server or Debian server (to run C++ apps developed on Ubuntu)

  - by skyeagle

  I have written a number of C++ server side daemons for my website, using my Ubuntu 9.10 dev machine. The C++ apps I mentioned above are "GUI-less" daemons (and libraries used by the daemons). I am now about to host my website and need to decide whether to go with Debian server or Ubuntu server. In a nutshell, here is the situation: I developed on Ubuntu desktop because I preferred the more friendly GUI I would like to deploy on Debian Server because of the (perceived?) robustness of the Debian server over Ubuntu server (I may be totally wrong here - and in fact, this is really what this question is all about) If Debian server is indeed more robust than Ubuntu server, then I have no choice but to go with Debian server - BUT, will my Ubuntu developed C++ apps run on the server? (or do I need to recompile them on the server? (I'd HATE to have to do this, because I want to keep the server machine clean and light - no GUI, no dev tools etc). This last question is really about binary compatability between Ubuntu and Debian. I want the server to be robust, secure and stable, and simply act as a server (i.e. LAMP and very little else - no GUI etc). Given that requirement, and the fact that I need to run my C++ apps (developed on Ubuntu 9.10), I need advice on which OS to choose for the server. Ideally, any advice will be backed with a reason. I am particularly interested in hearing from people who have been in an identical situation, or done something similar.

• Excel 2010 data validation warning (compatibility mode)

  - by Madmanguruman

  We have some legacy worksheets that were created in Excel 2003, which are used by LabVIEW-based test automation software. The current LabVIEW software can only handle the legacy .xls format, so we're forced to keep these worksheets as-is for the time being. We've migrated to Office 2010 and when working with these worksheets, I see this warning: "The following features in this workbook are not supported by earlier versions of Excel. These features may be lost or degraded when you save this workbook in the currently selected file format. Click Continue to save the workbook anyway. To keep all of your features, click Cancel and then save the file in one of the new file formats." "Significant loss of functionality" "One or more cells in this workbook contain data validation rules which refer to values on other worksheets. These data validation rules will not be saved." When I click 'Find', some cells that do indeed have validation rules are highlighted, but those rules are all on the same worksheet! We're using simple list-based validation, with some cells off to the side containing the valid values (for example, cell B4 has a List with Source "=$D$4:$E$4") This makes no sense to me whatsoever. One, the workbook was created in Excel 2003, so obviously we couldn't implement a feature that doesn't exist. Secondly, the modifications we're making don't involve changing the validation rules at all. Thirdly, the complaint that Excel is making is incorrect! All of the rules are on the same worksheet as the target. As if the story wasn't bizarre enough: I went ahead and saved the worksheet with Excel 2010. I then went to an old computer back in the lab and opened the document with Excel 2003. Guess what - the validations were untouched! My questions are: is this a legitimate bug in Excel 2010, or is this some exotic error in the legacy .xls worksheet that is confusing the heck out of Excel 2010? Has anyone else observed this issue working in compatibility mode?

• Transpose matrix-style table to 3 columns in Excel

  - by polarbear2k

  I have a matrix-style table in excel where B1:Z1 are column headings and A2:A99 are row headings. I would like to convert this table to a 3 column table (column heading, row heading, cell value). It does not matter in what order the new table is. A B C D A B C A B C 1 H1 H2 H3 1 H1 R1 V1 1 H1 R1 V1 2 R1 V1 V2 V3 => 2 H1 R2 V4 or 2 H2 R1 V2 3 R2 V4 V5 V6 3 H1 R3 V7 3 H3 R1 V3 4 R3 V7 V8 V9 4 H2 R1 V2 4 H1 R2 V4 5 H2 R2 V5 5 H2 R2 V5 6 H2 R3 V8 6 H3 R2 V6 7 H3 R1 V3 7 H1 R3 V7 8 H3 R2 V6 8 H2 R3 V8 9 H3 R3 V9 9 H3 R3 V8 I've been playing around with the OFFSET function to create the whole table but I feel like a combination of TRANSPOSE and V/HLOOKUP is required. Thanks EDIT I have managed to come up with the correct formulas. If the data is in Sheet1 like in my example above, the formulas go in Sheet2: [A1] =IF(ROW() <= COUNTA(Sheet1!$B$1:$Z$1)*COUNTA(Sheet1!$A$2:$A$99), OFFSET(Sheet1!$A$1,0,IF(MOD(ROW(),COUNTA(Sheet1!$B$1:$Z$1))=0,COUNTA(Sheet1!$B$1:$Z$1),MOD(ROW(),COUNTA(Sheet1!$B$1:$Z$1)))),"") [B1] =IF(ROW() <= COUNTA(Sheet1!$B$1:$Z$1)*COUNTA(Sheet1!$A$2:$A$99),OFFSET(Sheet1!$A$1,IF(MOD(ROW(),COUNTA(Sheet1!$A$2:$A$99))=0,COUNTA(Sheet1!$A$2:$A$99),MOD(ROW(),COUNTA(Sheet1!$A$2:$A$99))),0),"") [C1] =IF(ROW() <= COUNTA(Sheet1!$B$1:$Z$1)*COUNTA(Sheet1!$A$2:$A$99),OFFSET(Sheet1!$A$1,IF(MOD(ROW(),COUNTA(Sheet1!$A$2:$A$99))=0,COUNTA(Sheet1!$A$2:$A$99),MOD(ROW(),COUNTA(Sheet1!$A$2:$A$99))),IF(MOD(ROW(),COUNTA(Sheet1!$B$1:$Z$1))=0,COUNTA(Sheet1!$B$1:$Z$1),MOD(ROW(),COUNTA(Sheet1!$B$1:$Z$1)))),"") The formulas are limited to B1:Z1 for the headings and A2:A99 for the rows (these can be increased to their maximums if required). The COUNTA() formula returns the number of cells that actually have values, which limits the number of rows returned to headings*rows. Otherwise the formulas would could go on for infinity because of the MOD function.

• Verizon 4G LTE vs. a LAN

  - by n8wrl

  I have been having quite a bit of trouble getting my new Verizon 4G-LTE service running on a Windows 7 desktop. My desktop is on a LAN here at home with two other PC's. We all share printers, files, media, etc. Until yesterday, we also shared a Verizon 3G modem via a NetGear 3G broadband WAP. That isn't compatible with the 4G so now I am just trying to get the 4G modem working directly connected to one of the desktops. After some USB wrangling, it seems to work. Except, every 7-10 minutes the connection would drop. After some time on the phone with a very nice Verizon technician, it seems to be staying up - it's been up for 20 minutes now. He told me that my LAN was causing the 4G to drop. That traffic on my LAN, even though it is not destined for the internet (ICS not working yet) was causing the cell tower to detect an 'IP change' and a 'security violation' in my modem and drop my connection. Is this Verizon's way of forbidding more than one computer to share a modem? I have my computer running now without a LAN connection and the 4G is still up. But this isn't practical. Has anyone heard of this?

• Why do my Xcode default font starts to look ugly after some time, until I restart?

  - by mystify

  I plugged in an external monitor. All resolutions match perfectly. MacBookPro LCD is closed. After restarting Xcode editor fonts look very bad. Only in Xcode. When I restart the mac and DON'T use an external monitor, fonts look all right again. When I attach the monitor and close the LCD of the MacBookPro, fonts look nice. Then I close Xcode and reopen it: Fonts suck. Only way to get fonts look good is to disconnect external monitor and reboot, then reconnect external monitor, close LCD, wait, hit any key and let the external monitor be the only one. Fonts look nice - until I restart Xcode. I think it happens any time Xcode is launched with external monitor attached and ugly fonts survive until reboot. Unplugging external monitor and restarting Xcode doesn't help. It seems like Xcode isn't antialiasing them properly after something happens. Is there a fix for this problem? EDIT: After trying a few more times, it seems it is possible to get fonts to look nice by disconnecting external monitor and reopening xcode. Here are some little snapshots: GOOD FONT: UGLY FONT: You can see how dirty the ugly font looks. It's very hard to read and hurts in the eyes. Believe me. It sucks. Sometimes the little "i" are almost invisible. I make use of the very eye-friendly Dusk style of Xcode (go to preferences and choose that, if you haven't already. A real pleasure for your eyes)

• pppd disconnects from 3G, doesn't reconnect, w/ persist set

  - by bytenik

  I am trying to configure pppd to connect to a 3G network (Sprint, in this case) and then stay connected, reconnecting automatically if the remote connection is terminated. I have enabled the persist option. My configuration file is as follows: hide-password noauth connect "/usr/sbin/chat -v -f /etc/chatscripts/cellular" debug /dev/cell 921600 defaultroute noipdefault user " " persist maxfail 0 lcp-echo-failure 10 lcp-echo-interval 60 holdoff 5 However, when the peer disconnects the connection, pppd often waits a long time (substantially more than my holdoff) to reconnect the modem -- if it ever reconnects at all! An example log showing this: May 23 05:17:24 00270e0a8888 pppd[2408]: rcvd [LCP TermReq id=0x26] May 23 05:17:24 00270e0a8888 pppd[2408]: LCP terminated by peer May 23 05:17:24 00270e0a8888 pppd[2408]: Connect time 60.1 minutes.

Shouldn't persist + holdoff 5 cause this to automatically reconnect after 5 seconds of the link terminating?

• How to make multiple Excel files open in ONE window/instance of Excel 2003 in Win 7

  - by Mark

  I'm running Excel 2003 on my new Windows 7 machine. (There is also a Excel 2010 starter pre installed that I do not use). I'm a heavy user of Excel. I use it all day every day. I often have 10 or 15 sheets open and once and many of them have cell references to each other. I also have a macro file that keeps all my short cuts. On my old W2K machine when I clicked on a .xls file or a shortcut to one to it would open that file in the existing instance of Excel. This is as it should be. I would have many files open, in only one "window" or instance of Excel. All the files could interact with each other, the cross file lookups worked, my macros worked and I could switch between workbooks with CTRL Tab or CTRL F6, I could move tabs from one workbook to another. On the new W7 machine clicking on an icon opens a NEW INSTANCE of Excel every time. This is terribly frustrating. None of my connecting spreadsheets work anymore. My macros don't work. I can't connect files, I can't move tabs. I'm stuck. I can't do my work! I can still open files in one instance by doing a CTRL-O and navigating, but I need to my files to work on a click. I'm guessing this is a flaw in the registry files, possibly because of the starter Excel 2010 that came preloaded on my new machine. Can you walk me through a registry edit to fix this bug? Is there an easier way than a registry edit?

• Home Server: cpu virtualisation, what to choose?

  I'm looking for virtualisation solutions for storage and OS for a home server. A sort of private cloud where I manage the storage space independently of the VM one. This question focus on VM (or compute instance) management and what would best suit my needs. (I have another question related to the storage management). My use cases are: A backup server: rsync and other services running. A personal cloud server: a kind of owned dropbox system, à la ownCloud. " users foreseen. A media server: streaming videos and displaying photos. Here my environement and wishes: Server: HP Proliant MicroServer with 8 GB RAM (AMD Turion dual core with AMD-V technology) OS types: only Linux (perhaps a *BSD VM in the future) Linux distributions do not matter, I'm familiar with RHEL, Fedora, Suse, Ubuntu, but any other recommandation will be fine 2-3 VMs foreseen: backup server, owncloud server and media server (optional). Those are only servers, so no graphical console needed (I don't need VirtualBox) By VM I mean a virtualised environment like KVM, Xen, etc. or a compute instance like with OpenStack storage should be "virtualised/cloudified" see my other question. VM should be able to be migrated to another server in the future if performance cannot be fullfilled anymore by the current server It does not matter if installation of such setup is complicated as long as management tools allow for easy maintenance I don't have Windows at home, so solution should be Linux friendly and would be nice to be web based. But native apps are OK too. System should be easy to enhance: by adding a new server to migate some of the VMs to it. So it's really a kind of private cloud on which I could run some Linux OS. I would prefer free (libre, as in a free speach) and open source tools. But it does not have to be free as in a free beer. So Xen, KVM, VitualBox or OpenStack? What would you recommend?

• What is a good WordPress theme for long Objective-C code samples [closed]

  - by willc2

  As some of you iPhone developers know, Objective-C can be a verbose language. Long, descriptive variable and method names are the norm. I'm not complaining, it makes code easier to read and code completion makes it easy to type. But damn! Check out this method name for getting a cell in a table view: -(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath; I have a WordPress blog where I publish my code samples as I'm learning the language. One thing I hate on other blogs is how the code won't fit in a column without that scroll bar or without wrapping around. It really made it hard for me to read and comprehend method names back when I was a super-noob (six months ago). Right now I use the clean-looking Fazyvo 1.0 theme by noonnoo. I love the look of it but the columns are just too narrow and it doesn't have support for wider ones. I could hand-modify it but then I'd have to maintain/redo those changes every time I updated it. Instead, I'm looking for a nice theme that has width control built-in and looks good at larger font sizes. Can anyone help? Note: I use WP-CodeBox for code syntax highlighting.

• What does this diagnostic output mean?

  - by ChrisF

  I recently had a fault with my broadband connection. It turned out to be a fault with the ISP's or teleco's equipment. My ISP posted this diagnostic, but while I understand it in general, I'd like to to know more about the details. I'm assuming that ATM means Asynchronous Transfer Mode and PPP means Point to Point Protocol. It was this that my router was indicating as the fault. xDSL Status Test Summary Sync Status: Circuit In Sync General Information NTE Status: NTE Power Status: Unknown Bypass Status: Upstream DSL Link Information Downstream DSL Link Information Loop Loss: 9.0 17.0 SNR Margin: 25 15 Errored Seconds: 0 0 HEC Errors: 0 Cell Count: 0 0 Speed: 448 8128 TAM Status: Successfully executed operation Network Test: Sub-Test Results Layer Name Value Status Modem pass Transmitter Power (Upstream) 12.4 dBm Transmitter Power (Downstream) 8.8 dBm Upstream psd -38 dBm/Hz Downstream psd -51 dBm/Hz DSL pass Equipment Vendor Name TSTC Equipment Vendor Id n/a Equipment Vendor Revision n/a Training Time 8 s Num Syncs 1 Upstream bit rate 448 kbps Downstream bit rate 8128 kbps Upstream maximum bit rate 1108 kbps Downstream maximum bit rate 11744 kbps Upstream Attenuation 3.5 dB Downstream Attenuation 0.0 dB Upstream Noise Margin 20.0 dB Downstream Noise Margin 19.0 dB Local CRC Errors 0 Remote CRC Errors 0 Up Data Path interleaved Down Data Path interleaved Standard Used G_DMT INP INP Upstream Symbols n/a INP Upstream Delay 4 ms INP Upstream Depth 4 INP Downstream Symbols n/a INP Downstream Delay 5 ms INP Downstream Depth 32 ATM Reason: No ATM cells received fail Number of cells transmitted 30 Number of cells received 0 number of Near end HEC errors 0 number of Far end HEC errors n/a PPP Reason: No response from peer fail PAP authentication nottested CHAP authentication nottested (I'm not sure that Super User is the best place to ask this, but two people have suggested I ask it here so here I am).

• how could application installations/configurations be easier in linux?

  - by ajsie

  although you can do anything in linux it tends to require a lot of tweaking in config files and reading a lot of manuals/tutorials before you can have it running in your way. i know that it gets a lot easier by time, and the apt-get installations with ubuntu/debian is heading the right way. but how can linux be more userfriendly for us in the future? i thought that if more is automated like an IDE environment, eg. typing svn will give us all the commands and description about each command when you move between commands with your keyboard. that would be great. but that's just one example. another is the navigation in the terminal between folders. now you have to type a lot just to jump from/to different folders. would be great with some more automatization here too. i know that these extra features will slow down the server, but its 2010 now, and these features are not that heavy for the cpu, but makes it more userfriendly and encourage maintainance of a server, not frighten u off. what do you think about this? should/could we have more user friendly linux environment in servers, something that has annoyed you a lot? a lot of things are done in the unix way, but maybe we should reinvent the wheel in some areas, cause apparently, its so...repeatingly today and difficult to do easy tasks. it should be easier i think..

• Installing Windows 7 over PXE, preferably with domain autojoin

  - by Ivan Vucica

  At an educational non-profit, I've inherited a previously set-up Windows domain that, after the first reinstall of the machines, we ended up not using by simply not joining machines back into the domain. Over last summer, before the annual reinstall for shipping machines to the summer school, I toyed with the idea of installing Windows 7 over network, instead of just imaging the machines. It took a bit longer than I expected to figure out the basics; honestly, I expected that Windows would be more friendly for PXE installation out of the box. What I'm interested in is best practices for installing Windows 7 over PXE with domain autojoin. I'd love it if the whole setup could optionally be hosted on a UNIX based system as well. I've had some success by preparing an ISO using Windows Deployment Kit, and loading the ISO into memory. This was needed since I wanted a menu, and I think I couldn't get PXELINUX to chainload into Windows' bootloader. Unfortunately, I couldn't figure out much about customization of the Windows setup in that timeframe nor could I get Samba to work properly; studying the stuff ended up being too lengthy, especially the portion where I edited a disk image on Windows and copied it outside. WDK didn't make things easier by mounting the disk image into RAM, and writing it in its entirety when done with it, making me a very sad boy. I've recently found a different approach, too, that appears to be closer to Microsoft's original idea for netboot deployment and does not involve ISOs. So my question boils down to the following. What exact approach do you use for netbooting Windows 7 setup? How can Windows 7 setup be best customized to be completely unattended, including installation on specific system partition and not destroying the data partition, creation of passworded admin and default user, choice of MAC-address-based hostname, and joining a domain? As much details as possible for everyone's future reference would be appreciated. WDS isn't a bad choice, but if a Linux-based install can be used, that'd be better.

• Setting up MySQL Linux slave with a Windows master

  - by philwilks

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

• OpenOffice Calc: How can I count the number of different items with data pilot?

  - by manu

  Hi all, I have a rather long spreadsheet with historical information of issues solved by some user on a collaborative environment. The spreadsheet have the following (relevant) columns date, week no., project, author id, etc... The week no. is calculated from the date, is basically the year concatenated with the week number within that year; for instance, both 2009-02-18 and 2009-02-20 yield the week number 200908 - the 8th week of year 2009; and 2009-02-23 yields 200909 - the 9th week of year 2009. I need to count how many different users (given by author id) contributed to some project, on a weekly basis. I have setup a data pilot with the week as Row Field, the project as the Column Field, and count-author as the Data Field. However, this counts the author id as different instances. This is not what I need. I need to count how many different users contributed to each project on a weekly basis. I expect to get something like: projects week Project1 Project2 Project3 200901 10 2 200902 2 7 Each inner cell containing how many different users contributed. With the count-author configuration, what I get is how many contributions (total) got the project on that week. Is there a way to tell OpenOffice Calc to do what I want?
