Wouldn't be using Zodiac here? Ah, I misunderstood. Yes, to access an HTTPS based repository, you need Zodiac. If all Zn+Zdc tests are green, that means you are good. I see that you get a ConnectionTimedOut error while connecting, that's like the very first step ;-) What I would do is: make sure you can access your HTTPS repo in other ways, using a regular browser and/or curl. You know, MC repo serving is just plain HTTP(S) with basic authentication: you should be able to list a repo or download a version using any other means. If that works, try to do the same using ZnClient, like this: ZnClient new username: 'marianopech' password: 'secret'; get: 'http://www.smalltalkhub.com/mc/SvenVanCaekenberghe/STON/main/Ston-Core-Sven…'. Good luck ! Sven PS: I also see you are using a numeric IP address, not a DNS name.

Re: [Pharo-dev] Metacello doubt

by Dale K. Henrichs

Guido, I created a test case and it turns out that there _is_ a bug in the bypass lock logic[1] . I'm going to push out a new version of the Metacello Preview (1.0.0-beta.32.8) in the next day or so and the bugfix for Issue #174 will _not_ be included in that release ...

If nginx is serving HTTPS (reverse proxy-ing) to zinc HTTP, then you are not using any zodiac TLS/SSL in Pharo at all, right ? Or in any case, you shouldn't. Because proxy-ing HTTPS to HTTPS would be unnecessary/inefficient. So, I would do two things: look at nginx's error logs and try to access the zinc HTTP server in Pharo directly, bypassing nginx by temporarily opening the firewall, or tunnelling over ssh, or quickly with curl locally on the machine - it should work. You can send me the PharoDebug.log if you want. One problem I can think of, but that is for the StHub people to answer, is whether all generated URLs are properly relative. If not, they will fail when proxied by nginx. BTW, does the whole of StHub fail in your setup or only some operations ?

Problem with Zinc and HTTPS

by Mariano Martinez Peck

Hi guys. I have my own instance of SmalltalkHub running with nginx serving HTTPS in 443 and forwarding to my image that is listening with Zinc with HTTP in a particular port. In the CentOS 6.4 64bits server I get a ConnectionTimeout when trying to browse any of the repositories. The same image in my mac, works without problem. A couple of things: 1) I installed openssl and all Zodiac and Zinc-Zodiac tests are green 2) I have installed ConfigurationOfZincHTTPComponents version 2.4.3 on a Pharo 2.0 3) Doing a ZnClient new get:'https://www.google.com' brings me (I think) the correct result 4) Doing a "ldd libSqueakSSL.so" in the VM of the server I get: ./libSqueakSSL.so: /usr/lib/libssl.so.0.9.8: no version information available (required by ./libSqueakSSL.so) 5) I am NOT using default HTTPS port, instead a different one. Anyway, I specify the correct URL in the shub repo. 6) I do have the PharoDebug.log. I can share it if someone is interested in helping me ;) 7) The image DOES have access to internet.
