Debian Stretch 9 – ARC client 6

Install ARC6 client

First add the repositories:

echo 'deb strech main\n
    deb-src strech main\n
    deb strech-updates main\n
    deb-src strech-updates main' \
>> /etc/apt/sources.list

Add the gpg key:

wget -q -O - | apt-key add -

Install the required packages:

apt-get -y install nordugrid-arc-client \
                   nordugrid-arc-plugins-needed \

Add EGI-trustanchors repository and install CA-s

Add the following content to /etc/apt/sources.list.d/EGI-trustanchors.list

echo 'deb egi-igtf core' > \

Add the key for the repository (you will need to install gnupg beforehand):

wget -q -O - | apt-key add -

Now install the certificates:

apt-get update
apt-get install ca-policy-egi-core fetch-crl

*fetch-crl package enables updating the CA-s automatically (create a cron job that should run a couple of times a day)

Configure the ARC client

ll settings should be in .arc folder within your home folder:

mkdir ~/.arc

Convert your certificate to the correct format and put the usercert.pem and userkey.pem to the .arc folder:

openssl pkcs12 -in usercert.p12 -clcerts -nokeys -out usercert.pem
openssl pkcs12 -in usercert.p12 -nocerts -out userkey.pem
chmod 400 userkey.pem
chmod 644 usercert.pem
mv userkey.pem ~/.arc/
mv usercert.pem ~/.arc/

In order to submit to the SLING clusters, you need to be a member of VO. You can request the membership at

Now configure the VO:

mkdir -p ~/.arc/vomsdir/
cat vomsdir/ 
mkdir ~/.arc/vomses
cat vomses/
