  • How to block internet access for wine applications?

    - by YSN
    Hello! Is it possible to prevent specific wine applications or any wine application from accessing the internet? When using certain apps under Windows, they were trying to access the internet from time to time without any obvious reason. I was able to prevent that behaviour with a personal firewall back then. Unfortunately I did not find an application level firewall in Ubuntu up to now. This is especially annoying when I am abroad using data-roaming with my 3G modem. Is there a way to prevent my wine-apps sending or receiving data without my knowledge. Thanks in advance! YSN

  • In SAP Functional a good career path ???

    - by Sam Ahmed
    Hi My name is Sam and I am 23 right know.I have graduated a year back in the domain of computer science.I am currently working as SAP SD consultant and have a project under my belt. Currently working in SAP seems price less as people are dieing for it but at the same time I have really strong academics and many people are forcing me to apply for masters abroad for which I have to leave this job.This decision seems to be really tough. This decision of moving to SAP sometimes makes me happy as it is valuable and on the other hand my technical skills are completey dieing. Most of my accomplishers in my family dont encourage me to be in SAP especially in USA and consider it as a mediocre career. Was my decision right or should I move back to technical and go for MS???

  • Is software innovation still primarily North American and European? Why, and for how much longer?

    - by limist
    Since this site is read by a global audience of programmers, I want to know if people generally agree that the vast majority of software innovation - languages, OS, tools, methodologies, books, etc. - still originates from the USA, Canada, and the EU. I can think of a few exceptions, e.g. Nginx webserver from Russia and the Ruby language from Japan, but overwhelmingly, the software I use and encounter daily is from North America and the EU. Why? Is history and historical momentum (computing having started in USA and Europe) still driving the industry? And/or, is some nebulous (or real) cultural difference discouraging software innovation abroad? Or are those of us in the West simply ignorant of real software innovation going on in Asia, South America, Eastern Europe, etc.? When, if ever, might the centers of innovation move out of the West? Your experiences and opinions welcome, thanks!

  • Lending epub files for limited time to users

    - by JP Hellemons
    I am looking for components to build a digital library who lends people epub (ebooks) for about a week. It's like a digital version of the offline old public library. Now I have found several flash (pdf) file streaming solutions. But that would require an active internet link. And like the public library, you are able to take your books to the beach or pool on holiday abroad where you have no connection. So streaming is no option. The other file restriction method I have found was DRM, but that would require a really expensive license of Adobe Content Server 4 which is not suitable for my little hobby project. But it seems that adobe content server and Adobe Digital Editions is the only option at the moment. Or are there open source alternatives?

  • How to copy a DVD [closed]

    - by ring0
    I was offered a couple of DVDs from abroad that cannot be played on my player due to region filtering. So I tried k9copy to copy the DVD (it removes the region automatically). But for some reasons the copy does not work well (followed the instructions from here but the generated ISO file does not work / not even in media player - additionally there are many bugs in k9copy 2.3.5 (latest from Ubuntu) showing that it is not a reliable software, at least not on Gnome...). My question is simple: how to copy a DVD on Ubuntu, the copy/ISO being as close to the original, but without the region code.

  • job offer in dead technology

    - by bold
    I have a job offer in a dead technology (specific programming language) that I don't want to work with nor do I believe it will offer many jobs in the future. It requires twice a year travels abroad, which not a plus in my eyes. On the other hand the money on the table is high. What would you do? edit: as its not clear I got a job in a programming language that is different from the academic programming language I worked with. Now I see it as a mistake to head to that direction.

  • SFTP jail & Keeping file ownership the same / File owner per folder

    - by Dragonshadow
    I want to setup a jailed SFTP account for a subfolder of another user's home folder, but want the owner of everything in that subfolder to stay the same, including new files and folders uploaded and created by the sftp user, while still allowing access to the files and folders of that subfolder as if the SFTP user was the parent user. rawny bawb-sftp /home/rawny <- rawny owns this /home/rawny/sftp <- rawny owns this too, but bawb-sftp can upload to it, edit files, etc bawb-sftp uploads a file /home/rawny/sftp/lol.txt rawny should still own the file, as if he made it in the first place, even though bawb-sftp was the one that uploaded it. Basically I guess I'm asking for an sftp jail that acts as a highly limited passthrough/puppet for another user?

  • User accounts in FTP

    - by Brad
    I have an FTP server(proftpd on debian) that I'm going to allow a couple friends access to, and I want some safety nets in place, just in case. These are some of the things I'd like to do: Jail the accounts to their home directories and impose a cap on the amount of data they can upload Allow them access to a shared folder(via symlink or something) where they have full access(Also with a storage cap, but larger) Allow my own account full access to the system(Using groups I guess) Not allow anonymous access, or allow it with its own folder, separate from the shared user folder Currently, I've got the accounts set up and jailed, but it seems like the symlink that I put in is not allowing them to visit the shared folder. I suppose this has to do with them not having read permissions anywhere but their own home directories, or maybe it's something else, I'll continue to look into it and provide any information that is requested. Is what I'm trying to do possible? Any tips or resources that you can share are appreciated. Thanks.

  • Is chroot the right choice for my use case?

    - by Anthony
    Backstory: I am working on setting up a MineCraft server and want to allow admins to have ssh access to the MineCraft server console and appropriate mc server files, but not the whole system. The console provided by the minecraft server is only available to the user that launched the process. In addition, the admins will need terminal access to some basic cli tools such as wget, cp, mv, rm, and a text editor. Plan: I have already setup the ssh aspect of things, requiring pre-shared keys and whatnot. Setup a jailed environment in which all user activity will be contained. Setup user accounts. - The first user account will be the minecraft user. The minecraft user will start the MC server in a multiuser screen session and allow the other admins to attach to it. - Subsequent users should have their own /home directory for normal usage. Setup acl for the appropriate files to allow each user to edit the mc server files. No one will be doing system updates, nor will anyone be installing any programs, so I'll be the only user with sudo. The Issues: I don't want the ssh users to have access to the whole system. Users will still need to use wget or curl to update the mc server files. Is chroot the right tool for this use case, or is there something more appropriate for the job? I have no experience setting up a chroot environment and have found several tools to aid in this process. Jailkit seems to be the most robust, but it's not in the standard repos.

  • chroot for unsecure programs execution

    - by attwad
    Hi, I have never set-up a chroot-jailed environment before and I am afraid I need some help to do it well. To explain shortly what this is all about: I have a webserver to which users send python scripts to process various files that are stored on the server (the system is for Research purpose). Everyday a cron job starts the execution of the uploaded scripts via a command of this kind: /usr/bin/python script_file.py All of this is really insecure and I would like to create a jail in which I would copy the necessary files (uploaded scripts, files to process, python binary and dependencies). I already looked at various utilities to create jails but none of them seemed up-to-date or were lacking solid documentation (ie. the links proposed in How can I run an untrusted python script) Could anyone guide me to a viable solution to my problem? like a working example of a script that creates a jail, put some files in it and executes a python script? Thank you very much.

  • ProFTPD Virtual User Directory

    - by Nik
    Alright, I'm trying to replicate a web hosting company's basic setup here by authenticating virtual users via SQL and redirect/jail them to their directory. I've accomplished most of the goals here, with the exception of redirect/jailing them to their directory. The directories are stored in /home/ftp and that's what DefaultRoot is set to. I want each individual user to have and be jailed into their own directory. It doesn't appear that setting homedir in SQL has any effect. Upon logging into FTP with any user, it logs into the DefaultRoot with no directory jailing or redirect. How do I accomplish this last task?

  • How to connect to my US network overseas via VPN?

    - by GiH
    I purchased an Apple TV for my parents and I have a netflix account. My parents live overseas, and I was wondering if they could use my account to get it to work. I read that it won't work unless you use proxies or a VPN, so I was wondering if its possible for me to setup a VPN to my network in the US instead of paying a service like StrongVPN? Setup: Router in US - Airport Extreme Router abroad - D-link (not sure of model) I know that the AppleTV doesn't have a built-in VPN client, maybe eventually when its jailbroken there will be an app, but as of now I'll have to use the routers right? Any other ideas are welcome as well!

  • Set preferred language in Chrome and other Google services

    - by Super Chicken
    Whenever I'm abroad and access Google's search (via Chrome browser, on my own laptop) or other Google services, they are presented to me in the local language. How can I get Google services displayed in English and instruct Chrome to use google.com (instead of the country-specific site)? My language setting in Windows is English, so Chrome should already use this by default, and I've also set my language preference in iGoogle to English (U.S.), yet if I'm in France, for example, my searches take place on google.fr and sites like the Google News are in French. Chrome tries to be helpful by suggesting to translate these pages for me, but it would be far better to direct to the original English version of these sites in the first place. How do I fix this?

  • Don&rsquo;t apply for your first job somewhere; apply for an experience at Oracle.

    - by cristian.condurache(at)oracle.com
    Hi! My name is Stijn and I currently work as a Business Development Consultant for Oracle in Dublin since November 2010. I’m originally from Belgium and I graduated last year from the Vlerick Leuven Gent Management School. In many ways you could say I’m living the life I asked for: an international career with global organization. I’m unbelievably grateful however, because opportunities like this don’t come by the dozen. Actually, going through university and business school my dreams of an international career were clouded quite quickly. Following all the ‘right’ steps wasn’t enough. The lack of offers for, and trust in, new starters to take on a challenge like this was a reality check for me and many of my friends. It takes a company that recognizes the opportunity of recruiting talented individuals by offering them something they actually want: a first job based abroad! My job is focused on generating demand for Oracle products over the phone. In only a few months, the amazing things I’ve experienced, the people I’ve talked to, the learning experiences I’ve had in and outside of work are too many to list. From having CEO’s on the phone, to having meetings with 15 different nationalities, to getting settled from scratch in a new country… it’s something that builds you as a person. But don’t be fooled though, it’s on you - where it starts. Although Oracle gives you the best training and resources to do your job and Ireland is a playground for everything else, it’s you that is responsible. You are in control and much is expected. What you get in return however, is beyond incredible. If you are interested in joining the same team as Stijn, please visit http://campus.oracle.com or contact [email protected] Technorati Tags: Oracle,opportunity,global organisation,career,Business Development Consultant

  • Role of Sharepoint experience in career growth

    - by Syed Ibrahim
    I am from India. I was a Mainframe developer for first 2 years of my IT career and then shifted to Microsoft .Net and completed 3 years as of now. In these 3 years as a .Net developer i have worked only in core .Net skills like Asp .Net, Sql Server with C# .Net. I never worked in advance skills like Web Services or WCF or silverlight etc. In current world market scenario, I feel Sharepoint experience weighs more than the WCF, Web Services work experience for a .Net Developer.(Please correct if wrong). So i am planning to study Sharepoint through some training centre and complete a Sharepoint certification. The main reason for me to go for Sharepoint is that i feel it is a niche skill and it will help me to get a job in abroad location in future. Please let me know whether sharepoint can help me to get a job in foreign location. I would also like to know whether, Is it possible to master Sharepoint without any experience in skills like WCF, Web Services etc? Is it possible to get a sharepoint job just with knowledge and certification in it? Incase if sharepoint will not offer me career growth, then can you please suggest me the skills which will offer great career growth (like foreign jobs) for me as a .Net developer?

  • Is C and Python enough?

    - by gruszczy
    I am very proficient in Python (including Django), which I use for most tasks. I am also quite confident with C; I am maintaining small file system in userspace written in C. Yet when I am browsing job offers I see everywhere Java/C# and sometimes C++. I have coded profesionally in C++ for half a year in a gaming company, but I don't consider myself a pro. Also I simply despise Java and C#, which I would prefer not to touch ever. But it seems to me, that I am at very unfavorable position, when it comes to career. I am browsing careers.stackoverflow.com and I don't see and pure python or C offers. I would like to find a new job abroad in about 6 months. If I find some python offer, it means doing web development (not my favorite job). Does it mean, that I have to quickly start improving my C++ skills, if I wish to find a satisfying job? What would you suggest me? EDIT Learning new technologies is not an issue. Company I am working in is an integrator. Basically every new project requires learning new technologies, sometimes custom made. During last two years I was writing SQLs by hand, using LDAP, writing GUI in Qt, working on large scale DBMS prototype, making our internal help desk system use gsm modem or writing own report system. In previous job I had to learn from basics everything what I could about games development, because I knew nothing and chose this job only because of the challene it posed. I am all about embracing new technologies. I have used Java in the past and simply didn't like it. It's dull and boring. Doesn't let me do anything cool. I have recently seen some C# in action and seems similar. I don't like it. It's like German. I don't like speaking German.

  • from MS Biology to BS Computer Science [on hold]

    - by Air Borne
    I'm Marco from Italy and I'd like to ask you a piece of advice about my career. I hold a Ms degree in Biology, I enjoyed a lot studying it and I got very good grades but I didn't know what to do with my degree in the real life. Few months ago, I began to read a book about Python programming (Introduction to Computer Science, Zelle J.) and I've great fun learning Python as a beginner, I wake up in the morning thinking about doing excersies and writing simple programs with python :) I'm also watching free lectures from MIT open courseware, and I'm feeling a certain degree of regrets for never asking myself what was computer science, since it seems to me it's a magic world. After weeks of doubts, I made a move :) I applied for a CS bachelor degree abroad, I got an interview and I'm going to start this great adventure next September. I feel incredibly excited at it, but a little bit scared too. Scared because sometimes I think I'm making a great mistake for my life restarting from a bachelor in a completely different area of study. Sometimes I hear people saying the IT market is bad, sometimes I hear other ones saying quite the opposite instead. Moreover, some colleagues of mine suggested me to try to get into Bioinformatics, instead of CS. My question is: I want to really discover if CS is for me, I mean the passion of my life. I know I'm just a beginner and I can't say nothing about it yet. What do you suggest me: CS or Bioinformatics? If I get a Bs in CS, could I get into bioinformatics without relevant experience, taking into account I have a Ms Biology degree? Any comment is appreciated, thanks in advance.

  • Providing SSH tunnling, what to think about when configuring Ubuntu Server

    - by bigbadonk420
    Recently I've considered, mostly as a pet project, to set up accounts for a closed group of users via SSH to my box with the purpose of SSH tunnling things like web traffic -- some of it for friends that live abroad and perhaps also to help some people bypass national censorship. There's some things I imagine that I need to do, such as: Disabling shell access by setting the shell to /bin/false or similar. Get some software that can track bandwidth usage on a per-user basis historically Make sure that each user can only use a certain amount of bandwidth. The reason I'm posting here to begin with is to look around and get some pointers regarding what kind of things I should read up on, as well as hearing if there are any software recommendations for doing what I'm trying to do. I already know a bit since I've actually gotten SSH tunnling up and running already, I just don't feel like letting it loose to other people without restrictions and some basic monitoring. I'm primarily trying to learn here, so if you think this is a Very Bad Idea (or if you have a better idea on how to do this) then by all means say so, but please include some information on how to do it :) (I'm also open to trying things like OpenVPN but it seems really hard to set up, also I've heard SSH more often works in locked down environments)

  • Korea&rsquo;s Anti Abortion / Pro Life Movement

    - by Randy Walker
    The South Korean government is in dire straits.  The national birth rate continues to decline and as the population grows older, there aren’t enough children being born to support the country long term.  The social issues of post Korean War are coming back to haunt the empowered nation.  Being torn apart by the Korean War (nicknamed the forgotten war in America) and with a nation facing starvation, South Korea allowed hundreds of thousands of their children to be adopted abroad.  This has created a problem of epidemic proportions, essentially devaluing life in Korea and child rearing. In an effort to encourage birth rates, the government encouraged their workers to go home early and procreate by turning off the lights in buildings.  Something unknown to me, was the illegalization of abortion except in special cases. According to the this article, http://joongangdaily.joins.com it’s working.  Abortions are down and women are being encouraged to give birth.  However the flip side is illegal risky abortions are on the rise, with potential back alley abortions looming.  But with a nation facing it’s potential implosion, it has to continue it’s efforts to encourage mothers to give birth. Many of the issues that America has faced is in stark contrast to South Korea.  Abortion has been a generally accepted procedure for some time.  If you’ll recall, I mentioned South Korea devalued their children.  But the nation’s problems lie so much deeper.  Being an Asian nation, saving “face” is an important aspect of life.  And being an unwed mother disgraces the family.  Living as a single mother in South Korea is a difficult life.  Most married mothers stay at home to take care of the children.  Being a shunned single mother that has a hard time getting a job (because you are a single mother) and affording child care isn’t like life in America. If we in the states suddenly faced a birthrate crisis, what would the U.S. government do?

  • How to correctly write an installation or setup document

    - by UmNyobe
    I just joined a small start-up as a software engineer after graduation. The start-up is 4 year old, and I am working with the CEO and the COO, even if there are some people abroad. Basically they both used to do almost everything. I am currently on some kind of training phase. I have at my disposition architecture, setup and installation internal documentation. Architecture documentation is like a bible and should contain complete information. The rest are used to give directions in different processes. The issue is that these documents are more or less dated, as they just didn't have the time to change them. I will be in charge of training the next hires, and updating these documents is part of my training. In some there is a lot of hard-coded information like: Install this_module_which_still_exists cd this_dir_name_changed cp this_file_name_changed other_dir_name_changed ./config_script.sh ./execute_script.sh The issues i have faced : Either the module installation is completely different (for instance now there is an rpm, or a different OS) Either names changed, and i need to switch old names by new names Description of the purpose of the current step missing. Information about a whole topic is missing Fortunately these guys are around and I get all the information I want and all the explanations I need. I want to bring a design to the next documents so in the future people don't feel like they are completely rewriting a document each time they are updating it. Do you have suggestions? If there is a lightweight design methodology available online you can point me to it's nice too. One thing I will do for sure is set up a versioning repository for the documents alone. There is already one for the source code so I don't know why internal documents deserve a different treatment.

  • Trying to run chrooted suPHP with UserDir, getting 500 server error

    - by Greg Antowski
    I've managed to get suPHP working fine with UserDir (i.e. PHP files run from the /home/$username/public_html) directory, but I can't get it to work when I chroot it to the user's home directory. I've been following this guide: http://compilefailure.blogspot.co.nz/2011/09/suphp-chroot-gotchas.html And adapting it to my needs. I'm not creating vhosts, I just want PHP scripts to be jailed to the user's home directory. I've gotten to the part where you use makejail and set up a symlink. However even with the symlink set up correctly, PHP scripts won't run. This is what's shown in the Apache error log: SoftException in Application.cpp:537: Could not execute script "/home/jimmy/public_html/test.php" [error] [client 127.0.0.1] Caused by SystemException in API_Linux.cpp:444: execve() for program "/usr/bin/php-cgi" failed: No such file or directory The thing is, if I try running either of the following commands in the terminal it works without any issues: /home/jimmy/usr/bin/php-cgi /home/jimmy/public_html/test.php /usr/bin/php-cgi /home/jimmy/public_html/test.php I've been trying for hours to get this going and documentation for this kind of stuff is almost non-existent. If anyone could help me out with this, I'd be extremely grateful.

  • Remote server security: handling compiler tools

    - by Gonzolas
    Hello! I was wondering wether to remove compiler tools (gcc, make, ...) from a remote production server, mainly for security purposes. Background: The server runs a web application on Linux. Consider Apache jailed. Otherwise, only OpenSSHd faces the public network. Of course there is no compiler stuff within the jail, so this is about the actual OS outside of any jails. Here's my personal PRO/CON list (regarding removal) so far: PRO: I had been reading some suggestions to remove compiler tools in order inhibit custom building of trojans etc. from within the host if an attacker attains unpriviliged user permissions. CON: I can't live without Perl/Python and a trojan/whatever could be written in a scripting language like that, anyway, so why bother about removing gcc et al. at all. There is a need to build new Linux kernels as well as some security tools from source directly on the server, because the server runs in 64-bits mode and (to my understanding) I can't (cross-)compile locally/elsewhere due to lack of another 64-bits hardware system. OK, so here are my questions for you: (a) Is my PRO/CON assessment correct? (b) Do you know of other PROs / CONs to removing all compiler tools? Do they weigh in more? (c) Which binaries should I consider dangerous if the given PRO statement holds? Only gcc, or also make, or what else? Should I remove the enitre software packages them come with? (d) Is it OK to just move those binaries to a root-only accessible directory when they are not needed? Or is there a gain in security if I "scp them in" every time? Thank you!
