Requirements

System requirements for HST Server.

Product-specific Aspera license file or entitlement.
Ubuntu 14.04 LTS, 16.04 LTS, 17.10; RHEL 6-7; CentOS 6-7; SLES 11-12; Debian 7-9; Fedora 26-27; Kernel 2.4 or higher and Glibc 2.5+. Linux distributions/kernels released after the product release date might not be compatible.
Glibc 2.5 or higher.
SSH Server. Version 5.2 or higher is recommended.
Screen resolution 1024 x 768 or higher for graphical user interface.

To use the Node API:

The line 127.0.0.1 localhost must appear in the hosts file:
/etc/hosts
For UNIX-based nodes, SELinux must be set to permissive or disabled, not enforced. Check the status of SELinux with the following command:
```
# sestatus
```
If SELinux is set to enforced, see Disabling SELinux. If SELinux is set to disabled or enforced, or if sestatus reports that SELinux is not installed on your system, you do not need to take further action.
To run node-to-node transfers, the remote node must have version 3.7.4 or later. Earlier versions use an SSH key type that is no longer accepted by servers as of version 3.7.4.

To support the HST Server web UI:

Perl version 5.8 or higher, including the Data::Dumper and Digest::MD5 modules.
Important: On some CentOS 7 and Fedora systems, the Perl modules Digest::MD5 and/or Data::Dumper are not present. If these dependencies are missing, their absence is reported in the install-command output.
Apache version 2.4.x.

The HST Server web UI supports the following web browsers:

Windows: Chrome 64-71, Microsoft Edge 41-44, Internet Explorer 11, Firefox 58-64, Firefox ESR 52-60
macOS: Chrome 64-71, Firefox 58-64, Safari 11-12, Firefox ESR 52-60
