 +=== Downloading files from other servers ===
 +You may need to download data from a server at another site.  Do not do this on ** //login2// **!  Use ** // scp.chpc.ac.za//​ ** for this purpose. ​ The easiest way of doing this is with the **wget** command:
 +
 +<​code>​
 +wget http://​someserver.someuni.ac.za/​pub/​somefile.tgz
 +</​code>​
 +
 +Very large files may be transferred more quickly by using a multi-threaded downloader. The easiest of these is **axel**, see [[https://​github.com/​axel-download-accelerator/​axel|axel'​s GitHub page]]. ​ The syntax is very simple:
 +
 +<​code>​
 +module load chpc/​compmech/​axel/​2.17.6
 +axel -n 4 -a http://​someserver.someuni.ac.za/​pub/​somefile.tgz
 +</​code>​
