Access and Login
Using Google Authenticator to login to SCSLab Cluster
Accounts on SCSLab Cluster require the use of Google Authenticator. The Google Authenticator provides a six digit one-time password users must provide in addition to their username and password to log into SCSLab Cluster.
Install Google Authenticator app on your mobile device using the instructions found under your device type on the left.
Telnet is disabled on SCSLab for security reasons. To login to SCSLab, you must use the Secure Shell (ssh):
ssh <ISU NetID>@scslab01.me.iastate.edu
ssh is usually available on any Linux or MacOS machine, and on Microsoft Windows 10. For older Microsoft Windows machines, we recommend using PuTTY ssh client .
The first time you ssh to SCSLab, it will respond with "host key not found, generate hostkey?(yes/no)". Answer yes.
Access to the SCSLab cluster is managed through ASW access lists, and PIs can add or delete users to/from the list for their group. Once a user has been added to the access list, he should login to the SCSLab cluster as described above. At the first attempt to login a GA account will be created for them, and the email with the instructions will be sent to <ISU NetID>@iastate.edu.
After installing and initializing GA as described in the instructions, login to the SCSLab cluster by issuing the same ssh command. Enter the 6-digit code generated by GA app when prompted for Verification Code and your ISU password when prompted for password.
GA account reset
Users may need to reset GA accounts when switching or reinstalling their mobile devices that have GA application installed. To be able to perform GA reset by yourself, save an SMS phone number in the system by issuing phone-collect.sh command on SCSLab. After doing that you will be able to do a self service reset of your GA at https://hpc-ga1.its.iastate.edu/reset/ .
ftp access into SCSLab is also disabled. To copy a file from another machine into SCSLab, issue the following command on that machine:
scp file <ISU NetID>@scslab01.me.iastate.edu:
This will copy the file into your home directory on SCSLab. Your home and group working directories are mounted on all nodes of the cluster.
Larger files should be kept in the group working directory (/data/<group>/<user>, where group is your group name, and user is your user name). On a remote machine issue
scp file <ISU NetID>@scslab01.me.iastate.edu:/data/<group>/<user>
to copy files directly to the group working directory. To find out your group, on SCSLab issue "groups" command.
On older Microsoft Windows machines one can use WinSCP or FileZilla to copy files to and from the cluster.
Login from off-campus
Access to SCSLab.its is limited to machines in the iastate.edu domain.To access this machine from a home computer install the ISU VPN using the following link: Installation of ISU VPN
