BwFileStorage Login Cluster

Cluster name: bwfilestorage-login.lsdf.kit.edu
(IPs:141.52.212.68, 141.52.212.69, 141.52.212.70, 141.52.212.71)
Monitoring:
bwfilestorage-login-01.lsdf.kit.edu
bwfilestorage-login-02.lsdf.kit.edu
bwfilestorage-login-03.lsdf.kit.edu
bwfilestorage-login-04.lsdf.kit.edu

The login cluster are directly accessible by end users. These nodes are used for interactive login, file management, data retrieving and restoring.
Four nodes are dedicated to this service but they are all accessible via one host name and a DNS round-robin alias distributes the login sessions to the different login nodes.

Environment Variables:

$SHELL=/bin/bash 
$USER=prefix_loginname
$BWFS=$BWFILESTORAGE=/bwfilestorage/prefix/prefix_groupname/prefix_loginname
$SNAPSHOTS=/bwfilestorage/prefix/.snapshots
$TEMP=/temp/prefix/prefix_groupname/prefix_loginname

prefix  : fileset name per organization; prefix for login name and group name

Using SSH from Unix client

Example:

>ssh -p 22 prefix_loginname@bwfilestorage-login.lsdf.kit.edu

Access per ssh key:

Example:

>ssh-keygen -b 2048 -t rsa -C "Login username"
>ssh-copy-id -i ~/.ssh/id_rsa.pub prefix_loginname@bwfilestorage-login.lsdf.kit.edu

Attention: Posix style file commands (for instance chmod) must not be applied on files on a CIFS share. This may revoke sharing and Access Lists (ACLs), steering the access to the files.

Using SSH from Windows and Mac client

Windows clients do not have a SSH client installed by default, so it needs to be installed before this protocol can be used.

Tools for example:

• OpenSSH
• WinSCP
• FileZilla
• Cygwin
• Putty suite
