Non-IATI specific tools¶
Wget is a common tool used for downloading files, including IATI data.
- The version of Wget in Debian stable is compiled against an older version of gnutls that fails on certain https links. Update your version of libgnutls if this is a concern. However, the one publisher with a failing https link has now changed their setup such that this is no longer an issue.
- By Default Wget assumes that your filesystem can’t handle unicode, and does not save unicode filenames properly. To force it to do so, use the --restrict-file-names=nocontrol flag.
- Some servers block Wget’s user agent. A different user agent can be supplied with -U, but these are also sometimes blocked. (See also Blocking User Agents)
- Older versions of Wget (e.g. 1.13.4) do not timeout properly if the connection hangs during an SSL/TLS certificate handshake. Additionally, even in the newest versions of Wget, timeout behaviour varies depending on which SSL/TLS library is linked against. For timeouts during an SSL/TLS handshake, the flag --read-timeout is needed if Wget is linked against OpenSSL, whereas --connect-timeout is needed if Wget is linked against GNUTLS.
