Copying large files over multi-gigabit networks
- Download latest version of UDT file transfer tool. The version we have been using is http://ivl.calit2.net/wiki/files/revisedudt3.3.tar.gz. Untar and unzip the file to a directory of your choice.
- Optimize network settings:
Change maximum UDP buffer size (read and write) on sender and receiver: edit /proc/sys/net/core/rmem_max and /proc/sys/net/core/wmem_max The number in the files determines the buffer size in bytes. We suggest the size to be 16MB (=16777216 bytes) for each of the buffers, which is the maximum allowed size.
- The following commands are called from the directory udt3.3/app/
- Run the sender:
./sendfile
- Run the receiver:
Syntax: ./recvfile <IP address/hostname of sender> <port number> <remote source file name> <local destination file name> Example: ./recvfile 127.0.0.1 9000 /home/jschulze/data/largefile.tif ./temp.tif
