Known issues and limitations

A list of known ETS issues and limitations.

  • Neural MT Language Pairs (version 7_4_x_x) are supported on Linux only. Windows support will be added in a future release.
  • Neural MT Language Pairs currently do not support the use of Dictionaries. From the Web GUI, Dictionaries selection for translation are disabled. Support to be added in a later release.
  • Network communication between Master and Worker hosts, Q-servers, and T-servers is in plain, unencrypted HTTP.
  • IPv6 is not currently supported.
  • The ETS application installer has to be run as root/admin.
  • When SMTP is disabled, local users cannot be created, nor can local users reset their passwords. LDAP users, however, can always be created so long as LDAP authentication is enabled.
  • For any language pair direction, only one engine can be installed at a time (e.g., AraEng_Generic and AraEng_Informal cannot be both installed on the same machine).
  • There can only be one Master host in an ETS cluster. ETS also do not allow for a Master host to add a remote Worker host that is controlled by another remote Master host.
  • Once ETS is installed in one of two modes (Master or Worker), it is not possible to switch between those modes without uninstalling/reinstalling.
  • Hostname can only contain ASCII letters, numbers, hyphens, and dots (/^[A-Za-z0-9\-\.]+$/).
  • SMTP server responsiveness directly affects the following ETS Web GUI features:
    • From the SMTP Configuration page, the Send Test Email action may have delayed status confirmation.
    • From the Users management page, the Create new user action may have a delayed refresh of the Users list.
    • From the Web GUI login page, the Send Password Reset Email action may have a delayed confirmation that the password reset email was sent.
  • When TLS is enabled, Browse Translate may not render http:// URLs properly.
  • Website with heavy Javascript elements may not be viewable with Browse Translate.
  • When a dictionary is uploaded, duplicate source segments are not detected at upload time, but will issue an error when trying to edit the dictionary via the Web GUI after upload.
  • ETS will authenticate to the proxy server using HTTP Basic Authentication only. Support for other authentication schemes is currently not available.
