Livermore Computing (LC) now offers two methods for moving files from the Open Computing Facility (OCF) to the iSNSI network. In addition to the existing method using tape technology and computer operator ‘sneakernet,’ a new method available now uses an electronic One Way Link (OWL).
From OCF to iSNSI
Sending Files
| File Transfer | Host Name | Alias | Transfer Method | Authentication Method |
|---|---|---|---|---|
| CZ only users: From OCF Collaboration Zone (CZ) or a desktop to the iSNSI | Snsifis.llnl.gov | snsifis | OWL | RSA OTP or Kerberos password of the day |
| Snsitapefis.llnl.gov* | snsitapefis | tape | ||
| RZ users: From OCF Restricted Zone (RZ) or a desktop to the iSNSI | Rzsnsifis.llnl.gov | rzsnsifis | OWL | CRYPTOCard OTP |
| Rzsnsitapefis.llnl.gov* | rzsnsitapefis | tape |
*this method is discouraged. Transfers only occur during normal working hours.
Retrieving Files
| Transfer Method | Host Name | Alias | Command |
|---|---|---|---|
| OWL | fastfis.llnl.doe.sgov.gov | fastfis | ftp, sftp, or Hopper |
| Tape | fis.llnl.doe.sgov.gov | fis | ftp or Hopper |
From iSNSI to OCF
Tape technology remains the only method available for users to transfer files from the iSNSI network to the OCF. To do this, users must first connect to tapefis on the iSNSI network. Data will be written to tape and transferred to the OCF by LC Operations staff. To retrieve transferred files on the OCF, users must connect to either snsitapefis (CZ) or rzsnsitapefis (RZ) depending on if the user is a CZ only or an RZ user.
