LSDF GridFTP Server

  • Host: gridftp.lsdf.kit.edu
  • Port: 2811

Grid Certificate

wget --no-check-certificate https://gridka-ca-sec.fzk.de/download/p12-2-pem-en.sh
chmod 755 p12-2-pem-en.sh
./p12-2-pem-en.sh usercert.p12
  • copy user certificate files in .globus folder:
mkdir -p $HOME/.globus/certificates
mv usercert.pem $HOME/.globus
mv userkey.pem $HOME/.globus
chmod og-rwx $HOME/.globus userkey.pem

ls -l $HOME/.globus/
drwxrwxr-x. 2 myname users 4096 Mar  9 08:29 certificates
-r--r--r--. 1 myname users 1999 Mar 15 09:28 usercert.pem
-r--------. 1 myname users 2004 Mar 15 09:28 userkey.pem
  • The gridftp client needs to trust the CA that issued the host certificate of the gridftp server. Therefore, you need copy the CA root certificate of the GridKa CA to the certificates subfolder:
cd $HOME/.globus/certificates
wget --no-check-certificate https://gridka-ca-sec.fzk.de/gridka-root-cert.crt
openssl x509 -in gridka-root-cert.crt -out 7ecb2657.0 -outform PEM
rm gridka-root-cert.crt

(remark: 7ecb2657 is a hash of the CA pem file:

openssl x509 -hash -noout < 7ecb2657.0
7ecb2657

)
Create a text file called 7ecb2657.signing_policy with the following content:

access_id_CA  X509   '/C=DE/O=GermanGrid/CN=GridKa-CA'
pos_rights    globus CA:sign
cond_subjects globus '"/C=DE/O=GermanGrid/*" "/O=GermanGrid/OU=*"'
ls -l $HOME/.globus/certificates
-rw-r--r--. 1 myname users 1631 Mar  9 07:35 7ecb2657.0
-rw-r--r--. 1 myname users  267 Mar  9 07:35 7ecb2657.signing_policy
