I'm trying to encrypt some files on Amazon S3 using server side encryption. According to this link
http://s3tools.org/kb/item9.htm
I should only add this flag
--server-side-encryption
on the put or sync command I'm trying to run, but when I do that I get a "s3cmd: error: no such option: --server-side-encryption" message.
How do I run this command to use server side encryption?
s3cmd put file.zip s3://test/file.zip
I'm using ubuntu 14.04 server 64 bits.
You need a more recent version of s3cmd than what is in the ubuntu repositories. Use github.com/s3tools/s3cmd master branch (preferred), or the copy in the Debian experimental repository.
If you've upgraded- make sure you don't have any remnants of the old version. I had this issue because I had installed the first package via the system package handler but when I upgraded I had installed via python. This left me with the impression that I had upgraded- but had not removed the old version.
I discovered this because
dpkg -l s3*
Still lists v 1.1 while
pip list | grep s3
Shows 1.6.1
I fixed the issue by uninstalling the old package using the system package handler.
dpkg -r s3*
Then when the cron job ran, it ran the python package version 1.6.1 and no errors occurred.

I am trying to install gnocchi-api, gnocchi-metricd and python-gnocchiclient with apt-get. I found that the postinst scripts in /var/lib/dpkg/info have some misconfigured ports due to which I cannot install the packages successfully. I wanted to ask if there is a way to change the post-installation scripts nad then re-install the package.
Thanks.
Ideally this kind of problems would be solved by filing a bug report (possibly with a patch) and letting the maintainer upload a fixed version that you can upgrade to.
If you need an immediate local workaround though, you could do the following:
Either apt download <package> or dpkg-repack <package> if for example this is a local package only, or the archive does not contain the version you are interested in f.ex.
dpkg-deb -R <package_version_arch>.deb bin-dir
sensible-editor bin-dir/DEBIAN/postinst
sensible-editor bin-dir/DEBIAN/control ideally to bump the version to mark this as a local modification, say by appending +local1 or similar.
dpkg-deb -b bin-dir .
dpkg -i <package_local-version_arch>.deb
In the R FAQ section 4.6 (Package TclTk does not work) I found the following sentence:
... although they [missing Tcl/tk packages] may be downloaded via the Teacup facility
What is "teacup"? How can I install and use it?
I am using RStudio running on Ubuntu Linux and Windows 7.
Teacup is a program that ships as part of ActiveTcl, a commercial zero-cost distribution of Tcl (and Tk and many other packages) for various platforms. It does package management, looking after the key part that is download, installation and upgrading of packages from a remote repository. It is not open source, though Tcl itself is (as are the majority of packages that aren't single-company-specific).
If you've got it installed, you use these commands from a shell:
teacup update-self
teacup update
Depending on where your Tcl installation is, you might need to elevate privileges to make these command calls work. How you do this is platform-dependent; on Unix it's usually simplest to use sudo for each of the commands, whereas on Windows it is probably easier to create an elevated command shell and run inside that.
Depending on your site, you might need to configure a web proxy with teacup proxy. Try without first.
If you're using a non-ActiveTcl installation but you have an ActiveTcl installation present, you can still use teacup. You just need to use teacup link to connect that Tcl installation to the teacup local repository. This is slightly more complex because you can have multiple repositories on the one system (though I've never needed that).
First, you find where the repository is:
teacup default
Then you need to link the shell to the repository:
teacup link make $PATH_FROM_TEACUP_DEFAULT $LOCATION_OF_TCLSH_TO_LINK
Making this work with R Studio will be a matter of determining which Tcl installation it is using. If it's already an ActiveTcl, you just need the first part of this answer. Otherwise, you need the second part as well. Also note that pretty much requires that you be using either Tcl 8.5 or 8.6; there are no guarantees for older, unsupported versions.
I'm trying to setup PHP, apache environment on HP-UX server. While install i'm using usual commands of "./configur, make, make install". Here when I'm trying to install PCRE I got an error like follows.
CDPATH="${ZSH_VERSION+.}:" && cd . && /bin/bash /home/ubuntu/softwares/m4-1.4.17/build-aux/missing aclocal-1.14 -I m4 /home/ubuntu/softwares/m4-1.4.17/build-aux/missing: line 81: aclocal-1.14: command not found WARNING: 'aclocal-1.14' is missing on your system.
You should only need it if you modified 'acinclude.m4' or
'configure.ac' or m4 files included by 'configure.ac'.
The 'aclocal' program is part of the GNU Automake package:
<http://www.gnu.org/software/automake>
It also requires GNU Autoconf, GNU m4 and Perl in order to run:
<http://www.gnu.org/software/autoconf>
<http://www.gnu.org/software/m4/>
<http://www.perl.org/> Makefile:1496: recipe for target 'aclocal.m4' failed make: *** [aclocal.m4] Error 127
So I download latest versions of "m4, autoconf and automake" source and try to install using usual make command.
First I tried to install "automake" it through error asking to install "autoconf"
Then I tried to install autoconf again it ask to install "m4"
Then I tried to install "m4" now it through the same error above listed.
So it became a loop of same set of error not letting me to install.
Can any one help me to sort this issues. Please consider this is a HP-UX unix server so don't recommend the famous ubuntu "apt-get install" command or red hat specific commands.
First read William Pursell's comment to your post (above). If you still need to install the autotools ...
Check to see what, if any, autotools you may already have installed by typing: m4 --versionand autoconf --versionand automake --version.
You should use HP-UX's package manager. It's called Software Distributor (SD). http://en.wikipedia.org/wiki/Software_Distributor
HP-UX's FAQ 5.9 explains how to handle dependencies using depothelper. http://hpux.connect.org.uk/hppd/answers/5-9.html
Here is where you find the correct autotool packages (autoconf, automake, libtool) for HP-UX. Install these HP-UX packages using HP-UX's native package manager instead of compiling from source. http://hpux.connect.org.uk/hppd/packages.html
I was facing the same problem with m4. In my case, the problem was I was transferring all the source files via scp to a server.
When I tried to configure, make and make install through ssh, this kept happening. I believe something did not transfer the way it was supposed to.
The problem was solved by manually transferring the files
through a USB.
It's not a perfect solution (it implies physical access to the server) but it works.
I'm new to R and I decided to put R on a machine I have and see if I can remotely run code that is on my desktop computer.
While searching for "how to do" that, I came across the names "Rserve" and "RStudio". As far as I could tell, RServe is a package (actually, it seems to be the package) which I can use to configure the server, while RStudio is an IDE.
My question is: does RStudio use RServe "under the hood"? And, if it doesn't, then how does RStudio compare to RServe? (I.e., which one is better and why?)
[I figured out that this question could possibly be a duplicate, but I couldn't find any similar question]
Rserve is a client server implemenation written in pure c that starts a server and spawns multiple processes each with it's own R workspace. This is not threads but processes due to R's limitation on multithreading. It uses a QAP packing protocol as it's primary form of transport between the client and the server. You execute commands via the client (PHP, Java, C++) to the server and it returns you REXP objects that are essentially mappings to R's underlying SEXP data objects. Rserve also offers a websockets version that does will can transmit data through websockets but the api is not well documented. It also supports basic authentication through a configuration file.
Rstudio is a C++ and gwt application that provides a web based front end to R. AFAIK it uses json as it's primary transport and supports authentication through pam. Each user has a workspace configured in their home directory. It runs a server very similar but not the same as Rserve to communicate with R using RCPP. It also has it's own plotting driver used to wrap the plot device so that it can pickup the plots to be served to the ui. It has much more functionality such as stepping through your code from the ui and viewing workspace variables.
Functionally they are similar in that they provide a client/server connection to R but IMHO the comparison stops there.
I believe they are separate projects (though I could be wrong). I've never heard of RServe and there does not appear to be any mention of it in the documentation for RStudio. I have used and would recommend RStudio Server. It is relatively easy to set up and super easy to use once it is set up. This is a helpful guide to setting up a server on Amazon EC2:
#Create a user, home directory and set password
sudo useradd rstudio
sudo mkdir /home/rstudio
sudo passwd rstudio
#Enter Password
sudo chmod -R 0777 /home/rstudio
#Update all files from the default state
sudo apt-get update
sudo apt-get upgrade
#Be Able to get R 3.0
sudo add-apt-repository 'deb http://cran.rstudio.com/bin/linux/ubuntu precise/'
#Update files to use CRAN mirror
#Don't worry about error message
sudo apt-get update
#Install latest version of R
#Install without verification
sudo apt-get install r-base
#Install a few background files
sudo apt-get install gdebi-core
sudo apt-get install libapparmor1
#Change to a writeable directory
#Download & Install RStudio Server
cd /tmp
wget http://download2.rstudio.org/rstudio-server-0.97.551-amd64.deb
sudo gdebi rstudio-server-0.97.551-amd64.deb
#Once you’ve installed the above commands, you can now access RStudio through your local browser. Navigate to the Public DNS of your image on port 8787, similar to:
#http://ec2-50-19-18-120.compute-1.amazonaws.com:8787
The earlier answer about 3 years old provide old information, such as here.
Updated correction
RStudio is a firm that provides the open source RStudio IDE for R. They also sell commercial services such as RStudio Server Pro that markets itself with load balancing and related things. Apparently, the successuful open source project has lead the way to markets.
You may also mean Microsoft R Server, which is now called Microsoft Machine Learning Server?
There is also RServer by RStudio.
Anyway how to install both can be found here.
While bootstapping on AWS EMR - I am getting the following. Any clues how to resolve it?
/mnt/var/lib/bootstrap-actions/1/STAR: /lib/libc.so.6: version 'GLIBC_2.14' not found (required by /mnt/var/lib/bootstrap-actions/1/STAR)
It's probably caused by not having high enough version of libc6.
You can SSH into the EC2 instance the EMR job created by following this: Open an SSH Tunnel to the Master Node
Then update the packages, for example, if your instance uses ubuntu, you should do sudo apt-get update. The command depends on which distribution of linux you are creating on your ec2 instance. The default emr job uses Debian, and Amazon linux is built based on redhat.
See if this would work.
If this is actually the problem, you can add this update package command (with ignoring Y/N prompt) at the start of your bootstrap script.
