• Process limit for user in Linux

  - by BrainCore

  This is the standard question, "How do I set a process limit for a user account in Linux to prevent fork-bombing," with an additional twist. The running program originates as a root-owned Python process, which then setuids/setgids itself as a regular user. As far as I know, at this point, any limits set in /etc/security/limits.conf do not apply; the setuid-ed process may now fork bomb. Any ideas how to prevent this?

• Let apache run a command as another user

  - by vise

  I have a web application that runs a program which needs X. I'm using xvfb to launch it; I want to run it as another user. I could probably do sudo -u username -p password my command. However, I'm not feeling too good about storing the users password in plain text. Is there a "smarter" way of doing this?

• Configuration Deployment to Linux Systems

  - by William

  Hello, I'm looking for a nice way to add / remote ips (and possibly interact with an asset inventory system to track where ips are), start / stop processes, download logs, and all around genearal system admin duties from one place. It's okay if I require more than 1 program. That would still be better than having 50 million terminals open and trying to trace ip assignments etc on whiteboards. I'd also like to know if anyone knows any good asset management programs. Best Regards, William

• What is the best way to configure windows firewall to open up sql server to lan computers

  - by Breadtruck

  Should I configure a specific port for SQl Server and open that port up to the lan ip address range or open up the firewall based on the program, and wouldn't this require making a rule for each instance? Do I need to add sql browser as a rule if I want lan computers to see the sql server instance?

• How can I archive a 30 GB file?

  - by Joel Coehoorn

  I have a 30 GB zip file containing an archive of digital materials available in the school library that I want to burn to DVD. Of course, 30 Gb is far too large for a single DVD and the content is already zipped. I'm open to ideas, but leaning towards suggestions that will help me automatically spread the file over multiple DVDs, including a simple program to stitch it back together again later.

• Index a set of files to search their text quickly?

  - by Ricket

  I have a unique need: I am frequently searching a large set of text files for a keyword. Right now, I open up Notepad++ and use the "Find in files" feature. It works just fine, but with the amount of files, each search takes several minutes to complete. Is there a good program more suited for this purpose, perhaps that indexes a set of files and then lets you search the set repeatedly and very quickly? It would greatly speed up my workflow.

• Noob proftpd questions

  - by Camran

  I have setup my VPS pretty much now, and want to upload some basic files to the server. How is this done in Ubuntu 9.10? I have PuTTY and use the terminal there... Is there any ftp program, like in regular managed hostings, to just upload files with? I was thinking about proftpd, but don't have a clue how to get it to work. I am using my home-laptop with windows xp to command the VPS. Thanks

  Currently I'm using OO Defrag, perhaps the best defragmentation program there is. I'm looking for a free/open source alternative with at least powerful defragmentation algorithms. I looked at Defraggler but it's too simplistic. What are some powerful ones?

• Can you tell by the network traffic whether a video was watched or downloaded from YouTube?

  - by humanityANDpeace

  My question is about quite popular YouTube downloaders like youtube-dl (a command line program) or VideoDownloadHelper (a Firefox-browser extension). Comparing two cases: Watching a video on YouTube Download the video using a downloader (to be specific let's assume youtube-dl) Is it possible to tell – for instance by inspecting the network traffic – that the video was downloaded and not "only watched" on YouTube? Maybe one could compare network traffic using programmes like Wireshark? I cannot do that myself, but maybe this will help somebody to answer the question.

  - by andresmh

  I'm at a summer program where about 30 students are taking collaborative notes during presentations. EtherPad works great for this but it has a limit of 8 users. Do you know any alternatives? Google Docs is not very robust for this kind of use (if you have used it before with more than 1 person you probably know).

• What is 'FizzBuzz' for system administrators?

  - by docgnome

  FizzBuzz is a simple test of programing ability, often used by employers to weed out people who can't actually program. Is there an equivalent test for system administrators and general IT guys? Clarification I'm looking for things that can be tested in an interview setting with some accuracy. Obviously, this isn't going to clearly determine the right person, just as FizzBuzz doesn't for programmers. I'm just looking to weed out people who think they can work as a system administrator/IT Person because they can surf the web.
