This command and file pair list create the following directories within the transfer user's docroot on the
destination:
/tmp1/folder1
/tmp2/folder2
Network shared location transfer
•
Send files to a network shares location \\1.2.3.4\nw-share-dir, through the computer 10.0.0.2:
# ascp local-dir/files root@10.0.0.2:"//1.2.3.4/nw-share-dir/"
• Parallel transfer on a multi-core system
Use parallel transfer on a dual-core system, together transferring at the rate 200Mbps, using UDP ports 33001 and
33002. Two commands are executed in different Terminal windows:
# ascp -C 1:2 -O 33001 -l 100m /file root@10.0.0.2:/remote-dir &
# ascp -C 2:2 -O 33002 -l 100m /file root@10.0.0.2:/remote-dir
• Upload with content protection
Upload the file local-dir/file to the server 10.0.0.2 with password protection (password: secRet):
# export ASPERA_SCP_FILEPASS=secRet ascp -l 10m --file-crypt=encrypt local-dir/file
root@10.0.0.2:/remote-dir/
The file is saved on the server as file.aspera-env, with the extension indicating that the file is encrypted.
See the next example for how to download and decrypt an encrypted file from the server.
• Download with content protection and decryption
Download an encrypted file, file.aspera-env, from the server 10.0.0.2 and decrypt while transferring:
# export ASPERA_SCP_FILEPASS=secRet; ascp -l 10m --file-crypt=decrypt root@10.0.0.2:/remote-
dir/file.aspera-env
Decrypt a downloaded, encrypted file
•
If the password-protected file file1 is downloaded on the local computer without decrypting, decrypt
file1.aspera-env (the name of the downloaded/encrypted version of file1) to file1:
$ export ASPERA_SCP_FILEPASS=secRet; /opt/aspera/bin/asunprotect -o file1 file1.aspera-env
• Download through Aspera forward proxy with proxy authentication
User Pat transfers the file /data/file1 to /Pat_data/ on 10.0.0.2, through the proxy server at 10.0.0.7
with the proxy username aspera_proxy and password pa33w0rd. After running the command, Pat is
prompted for the transfer user's (Pat's) password.
# ascp --proxy dnats://aspera_proxy:pa33w0rd@10.0.0.7 /data/file1 Pat@10.0.0.2:/Pat_data/
Test transfers using faux://
For information on the syntax, see
• Transfer random data (no source storage required)
Transfer 20 GB of random data as user root to file newfile in the directory /remote-dir on 10.0.0.2:
#ascp --mode=send --user=root --host=10.0.0.2 faux:///newfile?20g /remote-dir
Transfer a file but do not save results to disk (no destination storage required)
•
Transfer the file /tmp/sample as user root to 10.0.0.2, but do not save results to disk:
#ascp --mode=send --user=root --host=10.0.0.2 /temp/sample faux://
/local-dir
