Log on using ssh
One can log into the B4F Cluster (more specifically the nfs server) using ssh. The address of the nfs server is:
nfs01.hpcagrogenomics.wur.nl
To log on one has to use an ssh (secure shell) client. Such client systems are always available from Linux or MacOS systems. For Window an ssh-client may need to be installed. The most popular ssh-client for Windows is Putty.
CLI from a Linux/MacOSX terminal
A Command Line Interface (CLI) ssh client is available from any Linux or MacOSX terminal. Secure shell (ssh) protocols require port 22 to be open. Should a connection be refused, the firewall settings of the system should be checked. Alternatively, local ICT regulations may prohibit the use of port 22. Wageningen UR FB-ICT for instance does not allow traffic through port 22 over WiFi to certain systems.
<source lang='bash'> ssh [user name]@nfs01.hpcagrogenomics.wur.nl </source>
PuTTY on Windows
<need a volunteer to write some text here>
Log on to worker nodes
Once logged into the nfs server, it is then possible to log on to any of the worker nodes. Logging on to the worker nodes does not require password authentication, you should therefore not be prompted to provide a password. Before logging onto a node it should be checked whether that node is busy. Status of nodes can be ascertained through the BCM Portal.
<source lang='bash'> ssh [user name]@[node name] </source>
For instance:
<source lang='bash'> ssh dummy001@node049 </source>
File transfer using ssh-based file transfer protocols
Copying files to/from the cluster: scp
From any Posix-compliant system (Linux/MacOSX) terminal files and folder can be transferred to and from the cluster using an ssh-based file copying protocol called scp (secure copy). For instance, copying a folder containing several files from scomp1090/lx6 can be achieved like this:
<source lang='bash'> scp -pr /home/WUR/[username]/folder_to_transfer [username]@nfs01.hpcagrogenomics.wur.nl:/lustre/scratch/WUR/ABGC/
