• What does "Use mandatory profiles on the RD Session Host server" do?

  - by Scott Chamberlain

  The description for "Use mandatory profiles on the RD Session Host server" is a little ambiguous: This policy setting allows you to specify whether Remote Desktop Services uses a mandatory profile for all users connecting remotely to the RD Session Host server. If you enable this policy setting, Remote Desktop Services uses the path specified in the Set path for Remote Desktop Services Roaming User Profile policy setting as the root folder for the mandatory user profile. All users connecting remotely to the RD Session Host server use the same user profile. If you disable or do not configure this policy setting, mandatory user profiles are not used by users connecting remotely to the RD Session Host server. I have a situation where only some users need to use mandatory profiles for logging in to a Remote Desktop Session Host. If I have some users with ntuser.dat and some users ntuser.man in their roaming profile what will RD Session Host do To a user who has ntuser.man in their roaming profile and has the setting set to Disabled? To a user who has ntuser.dat in their roaming profile and has the setting set to Enabled?

• Get tarball of any public SVN repository

  - by Sridhar Ratnakumar

  Is there a website that allows one to get the tarball of any specified SVN repository? For example I want to get the tarball or zip of http://svn.python.org/view/python/trunk/ without having to use a local SVN client, but only use my browser or some command line HTTP client (such as wget). This is mainly for some old unix machines that do not have SVN client.

• Run Crontab anytime after 4pm

  - by EasilyBaffled

  I am trying to run a script through crontab in osx 10.8.5 that will run at 4:30. 30 16 * * 1-5 /Library/Frameworks/Python.framework/Versions/2.7/bin/python /Users/lego90511/PycharmProjects/Stock\ Scanner/stock_scanner.py But I realized today that, my computer is not always on at 4:30. So I added the fix * 16 * * 1-5. But then I realized it may not be at all between 4-5. How can I set crontab to run anytime after 4pm(16 cron time)?

• What is the difference between /sbin/nologin and /bin/false?

  - by Michael Hampton

  I have often heard it recommended that a user account should be disabled by setting its shell to /bin/false. But, on my existing Linux systems, I see that a great number of existing accounts (all of them service accounts) have a shell of /sbin/nologin instead. I see from the man page that /sbin/nologin prints a message to the user saying the account is disabled, and then exits. Presumably /bin/false would not print anything. I also see that /sbin/nologin is listed in /etc/shells, while /bin/false is not. The man page says that FTP will disable access for users with a shell not listed in /etc/shells and implies that other programs may do the same. Does that mean that somebody could FTP in with an account that has /sbin/nologin as its shell? What is the difference here? Which one of these should I use to disable a user account, and in what circumstances? What other effects does a listing in /etc/shells have?

• Securing RDP access to Windows Server 2008 R2: is Network Level Authentication enough?

  - by jamesfm

  I am a dev with little admin expertise, administering a single dedicated web server remotely. A recent independent security audit of our site recommended that "RDP is not exposed to the Internet and that a robust management solution such as a VPN is considered for remote access. When used, RDP should be configured for Server Authentication to ensure that clients cannot be subjected to man-in-the-middle attacks." Having read around a bit, it seems like Network Level Authentication is a Good Thing so I have enabled the "Allow connections only from Remote Desktop with NLA" option on the server today. Is this acion enough to mitigate the risk of a Man-in-the-Middle attack? Or are there other essential steps I should be taking? If VPN is essential, how do I go about it?

• Why doesn't this cron work?

  - by Alex

  I do "crontab -e" and add the following line: 0 9 * * * /usr/bin/python /home/g1/g1/utils/statsEmail.py > /home/g1/log/statsemail.log But it doesn't work! Why? The script itself works. Also, the log is empty. My other command in crontab is this, and it works: 0 9 * * * /usr/bin/python /home/g1/g1/sphinx/updateall.py > /home/g1/log/updateall.log

• Firefox cannot recognize certificates for well knows sites

  - by RCola

  When trying to connect to well known sites, for instance hotmail.com Firefox shows that This Connection in Untrusted. In the OptionsAdvancedCertificates it's configured to select one matching certificate automatically. Why Firefox does not trust current connection? Can it be Man-in-the-middle attack or it's something like broken certificate storage on my computer? UPDATE UPDATE2 Solved: the problem is Antivirus Web Access protection. It interferes with HTTPS connection. Similar to Man-in-the-middle? Why ESET cannot do it correctly?

• iotop for Linux kernel 2.6.18

  - by Lightsauce

  So it has to come to my attention that iotop isn't availalbe for 2.6.18 since it's less than 2.6.20 and requires Python 2.6+. I've done some research and came across this article: http://lserinol.blogspot.com/2009/09/io-usage-per-process-on-linux.html According to this, if these process have io stats in /proc/pid#/io (where pid# is the process #) it's doable regardless of the kernel version. So, in reality, I could upgrade Python to 2.6 and test out iotop. However, my flavor of Linux, CentOS release 5.5 (Final), only supports Python 2.4.3-44.el5 currently. If I were to do uninstall from yum, it doesn't look so pretty. It ends up wanting to uninstall 235 packages, most of which are very important! I read in one place, online (I forget the URL from yesterday), that you can install Python 2.6+ parallel to this one, and have the rpm install for iotop use that. Well, I didn't choose that route. I figured, what the heck, lets write iotop (not copying it, but reverse engineering it without actually looking at it's code/it in use) in bash. I thought it would just grab the /proc/pid#/io file and parse stats. So I wrote a script to grab the top 10 rchar, wchar, read_bytes, and write_bytes by collecting all these stats from all the /proc/pid#/io files, sorting them by each metric, then grabbing the top 10 highest values. The conclusion, the data seems completely useless. Does anybody know any resources for advanced Linux where I can figure out how to take these /proc/pid#/ directories and figure out what the heck they are doing with io on the disk? My main goal is to figure out what exactly is causing high load on my disk. I just know it's on the / partition (/dev/sda2 in this case), and I'm not really sure how to narrow it down without the help of iotop. If I run iostat to grab metrics for 1 minute, every second, the first result it gives me shows a high 'kB_read/s', so that makes me think, it's reading mostly. However, if I watch the update it gives me every second, it's actually just showing values for kB_wrtn/s. This makes me think the initial value iostat gives me is misleading.

• .htaccess redirect, from old dirty URL to a clean new URL with parameters

  - by JustAnil

  I have the following 2 links, I'm not great with .htaccess rules yet. Old URL: http://www.mywebsite.org.uk/donate/donate.php?charity_id=885&project_id=18111 New URL: http://new.mywebsite.org.uk/donation/to/885/18111 I want all the traffic coming from the old URL to the new url (including the parameters charity_id & project_id). I'm trying to learn .htaccess rules, but finding the tutorials online to be kinda vague. I'd really like a simple explanation on the .htaccess rules. (Give a man a fish, feed him for a day, teach a man to fish, feed him for a lifetime). The correct answer will be the answer with a simple and useful explanation (along with the rules if possible!).

• Restarting or stopping apache results in waiting forever

  - by steko

  I have two simple WSGI apps running on top of mod_wsgi and apache2 on a test development server. There is no mod_python on this machine. The WSGI configuration is as follows WSGIDaemonProcess tops stack-size=524288 maximum-requests=5 WSGIScriptAlias /tops /home/ubuntu/tops-cloud/tops.wsgi <Directory /home/ubuntu/tops-cloud> WSGIProcessGroup tops WSGIApplicationGroup %{GLOBAL} Order deny,allow Allow from all </Directory> WSGIDaemonProcess flaskal maximum-requests=5 WSGIScriptAlias /c14 /home/ubuntu/c14/flaskal/flaskal.wsgi <Directory /home/ubuntu/c14/flaskal> WSGIProcessGroup flaskal WSGIApplicationGroup %{GLOBAL} Order deny,allow Allow from all </Directory> If I make changes to the app, I need to restart the web server, so I would expect that a simple sudo service apache2 restart does what I need. Same goes for any changes to the config (e.g. number of maximum requests, etc). Instead, it never ends "waiting", like this: $ sudo service apache2 restart * Restarting web server apache2 ... waiting .................................................. until I just do CTRL-C. At that point, the only way to resume a working server is to kill the process and restart it, not very convenient. The same happens with the stop command. The error logs at the "debug" level show the following lines after a failed restart [Wed Nov 14 21:55:19 2012] [notice] caught SIGTERM, shutting down [Wed Nov 14 21:55:19 2012] [info] mod_wsgi (pid=9047): Shutdown requested 'tops'. [Wed Nov 14 21:55:19 2012] [info] mod_wsgi (pid=9047): Stopping process 'tops'. [Wed Nov 14 21:55:19 2012] [info] mod_wsgi (pid=9047): Destroying interpreters.

[Wed Nov 14 21:55:19 2012] [info] mod_wsgi (pid=9047): Python has shutdown. If I then try to restart again (with the process still running), I get the following error: * Restarting web server apache2 (98)Address already in use: make_sock: could not bind to address 0.0.0.0:80 no listening sockets available, shutting down Unable to open logs Action 'start' failed. The Apache error log may have more information. Unfortunately the Apache error log doesn't have anything. When apache2 is running properly, both apps work without any problem.

• using trickle to slow down browser

  - by tester

  according to trickle's man page, http://linux.die.net/man/1/trickle i can limit the download speed of a process, e.g. trickle -u 10 -d 20 ncftp to Launch ncftp(1) limiting its upload capacity to 10 KB/s, and download capacity at 20 KB/s. how would I go about limiting google-chrome or firefox with trickle? Edit: For those of you asking why I asked such an obvious question, I tried trickle -u 10 -d 20 firefox and I'm getting an error trickle: Could not reach trickled, working independently: No such file or directory firefox opens right after, but is definitely not rate limited...

• Different color prompts for different machines when using terminal/ssh?

  - by bcrawl

  Hi, I have 5 machines I constantly ssh into to do work. Its getting increasingly frustrating when I am issuing wrong commands on wrong boxes. Luckily I havent done anything bad yet. I wanted to know if there is any hack which I can hardcode which will display my prompt in different colors based on the machine I am ssh into? Such as blue for desktop1, purple for laptop, red for server etc? Is this possible? Currently I am using this command export PS1="\e[0;31m[\u@\h \W]\$ \e[m " taken from here http://www.cyberciti.biz/faq/bash-shell-change-the-color-of-my-shell-prompt-under-linux-or-unix/ but it obviously doesnt work across ssh. Also, if you have any other cool bash tips for helping me ease my sight will be wonderful. I got this tip which colors the man pages. http://linuxtidbits.wordpress.com/2009/03/23/less-colors-for-man-pages/

• Little PM side post...

  - by edgaralgernon

  When adding new team memebers... off set the ramp up time by 1) having pre built machines ready and and easy method of getting the lastest tools, code base etc. I'm fortunate enough to be at a client that has a machine ready built and loaded when the dev arrives, all they have to do is grab the code. 2) have tasks broken down so that dependencies are as minimal as possible. In other words, to over come the mythical man month issue (as recently mentioned on slashdot) make sure the tasks you hand out have few dependencies on each other. That way the new dev is able to be productive fairly quickly. Here's our historical lead time... the bump in Jan is due to added work, by 2/18 we had added 4 new people over the last two weeks. And amazing the time starts coming down: Here's our averag work time: again time ramps up as we are adding more tasks, but then starts inching back down through out Feb and March. It's not that we beat the Mythical Man Month, and in fact I still believe the book and idea are highly relevant. But if you can break the tasks down and reduce the dependencies between the task then you can mitigate the effect. The tool used in this case is from AgileZen.com and some of the wild swings are due to inexperience with the system initially... but our average times as measured by the tool are matching real life. Also the tool appearst to measure in 24 hour days and 7 day weeks. so it isn't as bad as it looks. :-)

• How to make sysctl network bridge settings persist after a reboot?

  - by Zack Perry

  I am setting up a notebook for software demo purpose. The machine has 8GB RAM, a Core i7 Intel CPU, a 128GB SSD, and runs Ubuntu 12.04 LTS 64bit. The notebook is used as a KVM host and runs a few KVM guests. All such guests use the virbr0 default bridge. To enable them to communicate with each other using multicast, I added the following to the host's /etc/sysctl.conf, as shown below net.bridge.bridge-nf-call-ip6tables = 0 net.bridge.bridge-nf-call-iptables = 0 net.bridge.bridge-nf-call-arptables = 0 Afterwards, following man sysctl(8), I issued the following: sudo /sbin/sysctl -p /etc/sysctl.conf My understanding is that this should make these settings persist over reboots. I tested it, and was surprised to find out the following: root@sdn1 :/proc/sys/net/bridge# more *tables :::::::::::::: bridge-nf-call-arptables :::::::::::::: 1 :::::::::::::: bridge-nf-call-ip6tables :::::::::::::: 1 :::::::::::::: bridge-nf-call-iptables :::::::::::::: 1 All defaults are coming back! Yes. I can use some kludgy "get arounds" such as putting a /sbin/sysctl -p /etc/sysctl.conf into the host's /etc/rc.local but I would rather "do it right". Did I misunderstand the man page or is there something that I missed? Thanks for any hints. -- Zack

• More Retro Games

  - by Matt Christian

  Last week I made 2 stops to my local game stores and spent a load of cash on a bunch of new retro games for my collection.  Here are the recent additions: NES - Mega Man 2 - The Adventures of Bayou Billy - Ducktales - Metal Gear - Super Mario Bros / Duck Hunt - Firestorm - Dragon's Lair - Bartman Meets Radioactive Man N64 - Superman 64 - Zelda: Ocarina of Time (in original box, box is in poor condition) Atari - Superman - Adventure - Donkey Kong - Raiders of the Lost Ark Dreamcast - Memory card with view screen - Space Channel 5 Genesis (all in case) - Jurassic Park - Sonic Spinball - Sonic the Hegehog 3 (missing manual) - Spiderman (also called Spiderman vs. The Kingpin) GameGear - Bart vs The Space Mutants Quite a large haul given it was all purchased in 2 days.  Although, Metal Gear I got for a great deal and almost considered buying their other copy simply to resale for more though I decided against it to let another lucky soul find it.  I may need to run over there again because I think they had TMNT 2 (NES) for around $6 and it usually sells for more than that.  I could have sworn I grabbed it and bought it but my receipt tells me differently. I also found my copy of Super Mario 3 and added that to my collection.  Unfortunately one of the corners of the label has begun to peel up pretty badly which sucks although it's still a good item for the collection. In other retro news, this weekend was Easter and while at my grandparents the cousins wanted to play on their NES which was not working.  Me being the retro NES nerd I am, grabbed a screw driver, some Windex, a few toothpicks, and a few cotton swabs and had it up and running under an hour (that includes eating dinner!).  The NES holds the games tighter, has a better connection, and works almost instantly.  I should do THAT for a living!

• Welcome to JavaOne!

  - by marius.ciortea

  Welcome to this year's JavaOne conference! We are glad you dropped by. We want to keep you informed of all the happenings around JavaOne: all the events leading up to the conference and all the events during the conference week itself. We'll cover announcements, news, planning (but we won't make you go to any meetings), and snafus (nothing that makes us look too bad, of course). We'll even throw in a contest or two to make sure you are paying attention. We'll post a couple of times a week, and then more frequently as we get closer to September. There's a group of us, and we cover the Java beat, JUGs, Oracle Technology Network, Oracle Solaris, and lots more. What do you want to hear about? Let us know.A group of us from the office went to see the movie Iron Man 2 (it just debuted in the United States) last week and it reminded us of Java, the Java community, and JavaOne. In all three cases, from many disparate (and sometimes seemingly incompatible) parts and people, something comes together that works, is cool, and helps make a better world. Right now, there are hundreds of little islands of planning, all busy answering questions for JavaOne: What sessions get selected? What goes in the Mason street tent (until a few weeks ago, Will there be a tent on Mason street?), What do the JUGS need? Which Oracle ACEs will be there? Can we do a surf theme at the OTN party? And, somehow, like an Iron Man suit, they all come together and work to make a great event. At least, we hope it will be great. That's for you to decide. Please don't be shy--give us your comments and suggestions. We'll be listening.P.S. You can attend Stark Expo online at Oracle.com/ironman2, where you can train to become a "Master Cloud Operative." I got my MCO certification. I wish I had a card to put in my wallet.

• Future Air Plane – A new world

  - by Rekha

  For the first time in my life, I wished I had more number of years to live. The world has evolved from the cave man life to the man who is almost The Creator. When I was about 12 years old, I was taken to Chennai Planetarium for my school excursion. That day we were made to lie down in a dark room and the ceiling was full of stars and planets. All those were just videos but the day still stands in my mind. Same kind of experience in real is waiting for our future generations.Even though the English movies have gone beyond imaginations, we still have chances to bring those imaginations to real. You must be wondering why all these hype. Recently Airbus unveiled a news on transparent Airplane in 2050. This Airplane will have a body transparent to view the sky from all sides of the airplane when we are flying high above the grounds. And it will have all possible technologies under one roof that would give immense pleasure for the passengers. The journey would be an unforgettable one for each one of us.

• Daten versionieren mit Oracle Database Workspace Manager

  - by Heinz-Wilhelm Fabry (DBA Community)

  Wie können extrem lange Transaktionen durchgeführt werden, also Transaktionen, die Datensätze über Stunden oder Tage exklusiv sperren, ohne dass diese langen Transaktionen 'normale' Transaktionen auf diesen Datensätzen behindern? Solche langen Transakionen sind zum Beispiel im Spatial Umfeld keine Seltenheit. Wie können unterschiedliche historische Zustände von Produktionsdaten online zeitlich unbegrenzt vorgehalten werden? Die UNDO Daten, die das gesamte Änderungsvolumen einer Datenbank vorhalten, gewährleisten in der Regel nur einen zeitlich sehr limitierten Zugriff auf 'ältere' Daten. Und die Technologie der database archives, auch bekannt unter dem Namen Total Recall, erlaubt einerseits keine Änderungen an den älteren Daten und steht andererseits ausschließlich in der Enterprise Edition der Datenbank zur Verfügung. Wie kann man die aktuellsten Produktionsdaten für WHAT-IF-Analysen verändern und währenddessen andere Benutzer ungestört auf den Originaldaten weiterarbeiten lassen? Ein SET TRANSACTION READ ONLY erlaubt keinerlei Änderungen und ist ebenfalls begrenzt auf die 'Reichweite' der UNDO Informationen. Zwar könnte man für derartige Analysen eine Datenbankkopie aus dem Backup aufbauen oder eine Standby Lösung implementieren, aber das ist doch eher aufwändig. Es gibt eine verblüffend einfache Antwort auf diese scheinbar komplizierten Fragen. Sie heisst Oracle Database Workspace Manager oder kurz Workspace Manager (WM). Der WM ist ein Feature der Datenbank seit Oracle9i, das sowohl in der Standard als auch in der Enterprise Edition zur Verfügung steht. Anders als in den ersten Versionen ist er längst auch Bestandteil jeder Installation. Um so erstaunlicher ist es, dass so wenige Kunden ihn kennen. Dieser Tipp soll dazu beitragen, das zu ändern.

• Ein Vortrag für die DOAG 2012?

  - by Franz Haberhauer

  Vom 20. bis 22. November findet in Nürnberg wieder die DOAG 2012 statt, die jährliche Konferenz der Deutschen Oracle Anwendergruppe e.V. - mithin die größte Veranstaltung rund um Oracle in Europa. Seit zwei Jahren ist dort auch Solaris ein Kernthema.Während in den ersten beiden Jahren Sprecher von Oracle den überwiegenden Teil der Vorträge zu Solaris gehalten haben, ist der Grundgedanke der Konferenz - und sicher ein wesentlicher Grund für viele der über 2000 Teilnehmer nach Nürnberg zu kommen - der Austausch von Erfahrungen zwischen Anwendern ergänzt durch Beiträge seitens Oracle. Dazu bedarf es natürlich der Anwender, die über ihre Erfahrungen berichten Der Call for Presentations ist gerade erschienen und offen bis zum 30. Juni. Man kann sich also in aller Ruhe Gedanken über mögliche Themen machen und vielleicht während eines Projektes die eine oder andere Notiz machen, um dann bei der Konferenz über Erfahrungen zu berichten. Solaris ist Teil des sogenannten Streams Infrastruktur und auf der Seite dazu findet sich vielleicht auch noch die eine oder andere Anregung für mögliche Themen. Erfahrungen rund um Solaris 11 sind sicher ein dankbares Themenfeld. Ein Vorteil für Referenten besteht im freien Eintritt zur gesamten Veranstaltung. Für Consultants und Partner mag es auch eine Motivation sein, im eigenen Spezialgebiet Kompetenz zu zeigen und sichtbar zu werden. Und wer keinen Vortrag einreichten will, mag sich vielleicht als Konferenzbesucher schon mal den Termin notieren: 20. bis 22. November 2012 in Nürnberg - man sieht sich
