Synergy Team Nick Bolton Posted September 16, 2019 Synergy Team Share Posted September 16, 2019 We are aware of an issue in Synergy 1.10.3 where an invalid OpenSSL function is called. This occurs on older versions of Linux, or versions of Linux with an older version of OpenSSL. openssl error: error:140C5042:SSL routines:ssl_undefined_function:called a function you should not call Please open a support ticket if you're experiencing this issue.

We will be working on fixing this issue in a future version. For now, please use version 1.10.2 if you're experiencing this issue. Where do I find this distribution? I have debian 10.

ywu Posted October 2, 2019 Share Posted October 2, 2019 Not sure what the consideration is but isn't it easier to open the old versions downloading for fallback? I reported the same issue happened on my Ubuntu 16.04 + OpenSSL 1.1.1d but just don't want to report another (series of) support ticket(s) to get/try the alternative (start from 1.10.2).

In the meantime, please open a support ticket. Thanks. Quote Link to comment Share on other sites More sharing options...
Jamie Newbon Posted November 5, 2019 Share Posted November 5, 2019 Hi Guys, Initial testing on this build looks to have solved the issue, would those affected by the TLS/SSL `undefined function` bug mind giving this version a try, and reacting to this post if it works, or posting and details below if it didn't. https://snapshots.symless.com/public/6556-tls/ Thanks Jamie Edit: updated link due to password protection, the link is public access now.

nleco Posted November 14, 2019 Share Posted November 14, 2019 (edited) I just tested this out briefly with my Macbook Pro (late 2013) running Mojave 10.14.6. It works and connects to a client using Ubuntu 16.04 LTS. I am able to go between screens and click around.
