ARC client on MacOS High Sierra

The MacOS packages are old and do not work with newer versions of ARC.

We suggest you to use a Vagrant box with preinstalled and preconfigured ARC client –  all settings are customized for Slovenian supercomputing network – SLING.

First install brew, if not available:

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

Then install the following software:

brew cask install virtualbox

Some OS-es are available here: https://app.vagrantup.com/bento

mkdir arcclient
cd arcclient
vagrant init bento/centos-7.4

Vagrantfile contains these settings:

Vagrant.configure("2") do |config|
  config.vm.box = "bento/centos-7.4"

Run it:

$ vagrant init bento/centos-7.4

$ vagrant up --provider virtualbox

Update the OS and install the required packages:

$ vagrant ssh -c /bin/sh
$ sudo yum -y update
$ sudo yum -y install epel-release
$ sudo yum -y install nordugrid-arc-client nordugrid-arc-plugins-globus
$ cd /etc/yum.repos.d/
$ sudo wget http://repository.egi.eu/sw/production/cas/1/current/repo-files/EGI-trustanchors.repo
$ sudo yum -y install ca-policy-egi-core fetch-crl

Now configure the client:
Download the vomsdir configuration and place it in the .arc directory within your home folder: vomsdir.tar.gz

$ mkdir .arc
$ cd .arc
$ wget http://www-old.sling.si/sling/wp-content/uploads/2017/11/vomsdir.tar.gz
$ tar xvf vomsdir.tar.gz
$ ls -la vomsdir
total 12

-rw-r--r--. 1 vagrant vagrant  68 Sep  8 08:07 voms.sling.si.lsc

Now configure the vomses. Download the configuration file to vomses directory: vomses.tar.gz

$ wget http://www-old.sling.si/sling/wp-content/uploads/2017/11/vomses.tar.gz
$ tar xvf vomses.tar.gz
$ ls -la vomses
total 24
drwxr-xr-x. 2 vagrant vagrant 119 Nov 28 11:02 .
drwxr-xr-x. 4 vagrant vagrant  75 Nov 28 11:06 ..

-rw-r--r--. 1 vagrant vagrant 175 Jan  4  2017 ops

Now configure the client (you can transfer this file) or copy-paste the following settings:

$ cat ~/.arc/client.conf
[common]
keypath=/home/vagrant/.arc/userkey.pem
certificatepath=/home/vagrant/.arc/usercert.pem
cacertificatesdirectory=/etc/grid-security/certificates
vomsespath=/home/vagrant/.arc/vomses

[computing/jost]
url=ldap://jost.arnes.si:2135
infointerface=org.nordugrid.ldapng
jobinterface=org.nordugrid.gridftpjob

[computing/nsc]
url=ldap://nsc.ijs.si:2135
infointerface=org.nordugrid.ldapng
jobinterface=org.nordugrid.gridftpjob

To copy the certificate from the host machine to the VM, you need to install vagrant-scp plugin. Type this command on the host machine:

$ vagrant plugin install vagrant-scp

Copy the certificate to the VM:

vagrant scp /home/barbara/.arc/userkey.pem /home/vagrant/.arc

vagrant scp /home/barbara/.arc/usercert.pem /home/vagrant/.arc

Your client is ready to be used.

Test it (back in the vagrant box):

arcproxy -S gen.vo.sling.si
