similar to: Running R in a sandbox

Dear R users, I am working with netcdf data of NCEP/NCAR Climate Reanalysis. R does have capability to draw isolines using "contour". However, I need not to draw but to export contours in any vector format. Is it possible? Thank you.

Hello, Is it possible to use R on public server where each user has its own restricted R session? In particular, how to prohibit some set of functions, for example, from "base" package? How to limit session operating memory and CPU time? What additional security considerations must be taken care of? -- Kind regards, Antonio Rodriges

Is there any documentation/tutorial that explains how to use virt-sandbox-service? After looking at some writeups about virt-sandbox-service, this looks like a good tool for something I need to do. But, following the "examples" I cannot get anything to work correctly. With a simple xfce install with httpd, lighttpd, and libvirt-sandbox installed, I tried: 1. virt-sandbox-service

I'm trying to build libvirt-sandbox under ubuntu 12.10 sudo apt-get install git build-essential lxc libvirt-bin libvirt-glib-1.0 libglib2.0-0 libglib2.0-dev gtk-doc-tools libxml2-dev libselinux-dev git clone git://libvirt.org/libvirt-sandbox.git cd libvirt-sandbox sudo ./autobuild The error I'm getting: make[2]: Entering directory `/home/user/libvirt-sandbox/build/bin' CC

I'm considering using virt-sandbox with lxc to sandbox and execute untrusted code like python scripts and compiled C code. Is it possible to limit CPU and Memory like is possible with lxc-execute and a config file? What are the defaults security settings? Is it completely isolated by default? What's the difference between lxc-execute and libvirt-sandbox? How can I use it in ubuntu?

Hi all. I have an old windows VM with an oldish cygwin that I use for the regression tests. Investigating one of the test failures, I see that it's for UsePrivilegeSeparation=sandbox, and it seems to be because setrlimit(RLIMIT_FSIZE, ...) is not supported. IMO, this isn't a big loss, since the most useful thing in the rlimit "sandbox" is the descriptor limits. Can anyone see

Dear all, I have been trying to set up the set up Libvirt Sandbox without success. I want to use virt-sandbox in order to run untrusted programs in a secure environment. I am had no knowledge about virtualization until a couple of days ago, so I am probably doing something wrong. The scenario is the following: Linode instance. OS that I have tried: Ubuntu 14.04, Ubuntu 14, Fedora 21. Both

I'm attempting to build/use libvirt-sandbox on Ubuntu 12.xx. Although I'm still working through dependency issues (including the need for libvirt >= 1.0.2 which is not packaged for ubuntu 12.xx) to build the sandbox code, I have a forward looking question. It appears libvirt-bin for Ubuntu likes apparmor as does most Ubuntu based packages using a LSM impl. However, as I understand

I am using the Paypal Library for ruby (http://dist.leetsoft.com/api/paypal/) I have been testing it in development mode and the paypal sandbox site. Now I have moved my application into production mode but the paypal url still goes to the sandbox site: https://www.sandbox.paypal.com/cgi-bin/webscr How do I change the paypal URL? -- Posted via http://www.ruby-forum.com/.

Recently I''ve found out some mentions to the "--sandbox" parameter to the "rails console" command. And I found the idea interesting, but since I''m using Sequel instead of ActiveRecord I guessed this wouldn''t work for me. But after talking about this subject in the Sequel mailing list, Jeremy Evans has brought to my attention that there are some

Hi, The systrace and rlimit sandboxes have been committed and will be in snapshots dated 20110623 and later. This diff adds support for pre-auth privsep sandboxing using the OS X sandbox_init(3) service. It's a bit disappointing that the OS X developers chose such as namespace-polluting header and function names "sandbox.h", "sandbox_init()", etc. It already forced me to

Hi, I'm using nmds command (library vegan) to analyze some fishing data. I'd like to plot not only points, but also the names of species and stations in a specified position. I used the command text(nmds$points[,1], nmds $points[,2],labels=row.names(nmds $points),pos=3,cex=0.5) But the labels are sometimes overlapped. Is there any way to use identify, or a similar command, to plot the

Hello, I have a setup similar to Rweb ( http://www.math.montana.edu/Rweb/ ): I get R scripts from users and need to execute them in in a safe manner (they are executed automatically, without human inspection). I would like to limit the user's script to reading from STDIN and writing to STDOUT/ERR. Specifically, preventing any kind of interaction with the underlying operating system (files,

I hope this question isn't considered too off topic for this list, I am trying to reach the libvirt-sandbox developers, but I could not find a libvirt-sandbox specific mailing list, and it seemed to me that libvirt-sandbox was a part of libvirt itself. I am trying to port libvirt-sandbox to run on a CentOS 6.5 system. This wasn't too hard but, I had to do the following: I have used the

Z-Man, DHH recently said: "And [_why''s] latest work on sandbox looks stellar. Making it drop-dead easy to run multiple Rails applications in the same Mongrel process without conflicts. Thumbs up to both him and Matz for getting Sandbox on track for inclusion with the next Ruby release." Does that mean what I think it means - that one or more Mongrel processes may one day be

I was wondering if the following attack would be feasible once I'm able to break into rlimit sandbox. Because sandboxed process that handles unauthenticated session is running as the 'sshd' user I was wondering if this could be used to jump between processes using ptrace(2). For example if I find a bug in the code executed before authentication I could use ptrace(2) to attach to

Hi, I swear I have read almost all the posted messages about this issue, but it's evident I couldn't find an answer (surely esay) to my problem. What I want is the following: Make 8 days aggregates from a daily series like this (dput output): structure(c(6.91777181625366, 0.79051125049591, 9.00625133514404, 9.86966037750244, 14.4326181411743, 3.70155477523804, 9.67768573760986,
