Unable to download Cygwin from dedicated server

Unable to download Cygwin from dedicated server

[Simon Choucroun]

Hi guys,

We are renting a dedicated server at OVH Canada. For some reason, we get a 403 forbidden when trying to either download or visit Cygwin.com from the dedicated server. Can someone please take a look at this? The IP is 192.99.6.12

Thanks

Simon C

I would start with a Wireshark trace from the dedicated server to see
where it is actually going...

so far all of the past similar issues that I'm aware of have traced to
something on the requester's side blocking before it reaches cygwin's
servers.

This seems rather similar to [1] and re-reading that thread, I don't 
think we heard a resolution of the issue on this list.

Same advice applies though. I'd start by trying a different DNS server 
if you're able.

First rule of server config is no internet access.
First rule of server network config is block everything.
Everything else often has to be explicitly set up with holes poked in firewalls.
You may have to route connections over a tunnel to your own network then outward.
Contact your vendor for support.

Do you have the root CA server certs installed on your server, and are you
downloading using products which support those certs and HSTS?

I am sure there are firewalls between your server, the rest of the datacentre,
and the internet, for the vendor's protection, if not yours.

There are few files you may download directly from https://cygwin.com e.g.
setup-x86{,_64}.exe and detached .sig files. Try those first.
For the packages, you must go to a Cygwin public mirror site.
Can you download packages from public Cygwin mirrors?

If everything else works okay, you can try to contact Cygwin site operations
sourcemaster [at] sourceware [dot] org to see if, and reasons why, they may be
blocking your server from accessing https://cygwin.com.
You may want to get your vendor to contact them to resolve any issues.
