Really? I tried that, i.e. curl -o filename http://siderus.org/ipfs/Qm..., but to no avail. Only direct download in the browser worked. Maybe I did something wrong. (?) Will try it again.
Forgot to leave a update here. Tried to find the source code for the page linked in the above post, but couldn’t. Given it wasn’t minified, I just imported it into Github ( https://github.com/ipfs/public-gateway-checker ) so we could host it on Github Pages (in case the gateway stopped working for whatever reason).
If you come across new public gateways, a PR with adding it to the list, would be greatly appreciated!
Thanks @cbluth for the addition of the macholibre gateway!
Quick shell version. Note that sed substitutes “eternum” for “www.eternum”, which needs to be removed once the gateways list on Github has been updated.
