Access and Login

Using Google Authenticator to login to Condo Cluster

Accounts on Condo 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 Condo Cluster.

Install Google Authenticator app on your mobile device using the instructions found under your device type on the left.

 

Login

Telnet is disabled on Condo for security reasons. To login to Condo, you must use the Secure Shell (ssh):

  ssh <ISU NetID>@condo2017.its.iastate.edu

ssh is usually available on any Linux or MacOS machine. For Microsoft Windows machines, we recommend using PuTTY ssh client .

The first time you ssh to condo2017, it will respond with "host key not found, generate hostkey?(yes/no)". Answer yes.

Access to the Condo 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 Condo 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 Condo 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 condo2017. After doing that you will be able to do a self service reset of your GA at https://hpc-ga1.its.iastate.edu/reset/ .

 

File Transfer

ftp access into Condo is also disabled. To copy a file from another machine into Condo, issue the following command on that machine:

  scp file condodtn.its.iastate.edu:  

This will copy the file into your home directory on Condo. condodtn is the data transfer node. Your home and group working directories are mounted on all nodes of the cluster, including condodtn.

Larger files should be kept in the group working directory (/work/<group>/<user>, where group is your group name, and user is your user name). On a remote machine issue

  scp file condodtn.its.iastate.edu:/work/<group>/<user>

to copy files directly to the group working directory. To find out your group, on Condo issue "groups" command.

On Microsoft Windows machines one can use WinSCP or FileZilla to copy files to and from the cluster.
