How to Transfer Files
Both machines are on the UConn network
A safe way to transfer files to and from the cluster to a personal computer is to use the scp (Secure Copy) command.
The basic form of scp is
- Transferring to the cluster
scp /path/to/local/file.txt username@stats.phys.uconn.edu:/path/to/new/remote/location/
- Transferring from the cluster
scp username@stats.phys.uconn.edu:/path/to/remote/file.txt /path/to/new/local/location/
Transferring to/from offsite
Sometimes it is necessary to transfer files between your local machine and stats. This can become complicated if the local machine is not on the UConn network. In this case the connection is:
local machine -> intermediate UConn machine -> stats.phys.uconn.edu
The first step before being able to transfer files is to set up port forwarding in a separate terminal
Terminal 1: ssh -L9999:stats.phys.uconn.edu:22 <username for intermediate machine>@<hostname of intermediate machine> Ex: ssh -L9999:stats.phys.uconn.edu:22 TestUser@MiddleMachine.uconn.edu
Once the port forwarding has been set, files can be transferred between the two endpoints. To transfer a file from a local machine to stats:
Terminal 2: scp -P 9999 /path/to/local/file.txt <stats username>@localhost:/path/to/stats/file.txt
To transfer from stats to a local machine:
Terminal 2: scp -P 9999 <stats username>@localhost:/path/to/stats/file.txt /path/to/local/file.txt
For Windows Users
For Windows users it may be useful to download the program Cygwin. This is a Windows version of a terminal that has ssh and scp capability as well as many others. Using this program scp will look like the following
- Transferring to the cluster
scp /cygdrive/c/Users/<personalUsername>/My\ Documents/path/to/file.txt username@stats.phys.uconn.edu:/path/to/remote/location
- Transferring from the cluster
scp username@stats.phys.uconn.edu:/path/to/remote/file.txt /cygdrive/c/User/<personalUsername>/My\ Documents/path/to/local/location
Graphical Programs
Some users prefer to use a program with a graphical user interface (GUI) instead of the commandline. Use these at your own risk. In the past a student tried using such a program and lost all of the files being transferred.
