External Users Must Switch to Sponsored Accounts


External users of Virginia Tech ARC systems must switch to sponsored
accounts and shift their data files!

After 30 July 2017, a two factor authorization (2FA) scheme will be
necessary in order to access VT ARC systems. In turn, the
two factor authorization requires having a Virginia Tech PID.

Many VT researchers have external collaborators, who have been
given an “external” identifier, typically identified by a trailing
“-ext” suffix, with which they have gotten computer accounts and
set up file directories.

The 2FA system means that external researchers who wish to maintain
their access to VT resources must:

  1. apply for a sponsored VT PID;
  2. apply for new computer accounts under the new PID;
  3. shift files from the old PID account to the new one;

In more detail, external users should:

  1. begin by acquiring the necessary sponsored VT PID.
  2. enroll in 2FA using the sponsored PID, by going to the
    http://www.tech.it.vt.edu/2factor/ website;
  3. request an ARC account for the sponsored PID from the
    https://vt4help.service-now.com/sp?id=sc_cat_item&sys_id=2d1b7bfa0ff52680d3254b9ce1050e46
    website;
  4. once the new ARC account has been approved, log in to any ARC
    system using the new PID;
  5. migrate all the files from the old account (say “PID-EXT”) to the
    new account (say “PID”), by issuing a command such as:

    scp -r PID-EXT@blueridge1.arc.vt.edu:/home/PID-EXT/* /home/PID/
            

    where PID, PID-EXT should be replaced by the actual information,
    and instead of blueridge1, any ARC login node might be named;

  6. OR, the user can wait to have the files migrated by the system
    administrators, which will probably occur in late July.
