Dear Oleksandr, > And one more thing, as I understood, this code work only with recent > version of libssh. We should think, how can we make it available for > distributions like squeeze.

I have sent a bug report to Debian to include the missing patch. http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=688700 > I have a one notice. In your case HTTP protocol is used for proxy.

QNetworkProxy relies on QAuthenticator. QAuthenticator supports the following authentication methods: - Basic - NTLM version 2 - Digest-MD5 Which one is used depends on the setup of the proxy server. Squid has plugin for NTLM. NTLM and Digest-MD5 should be acceptable inside a private network. After the connection is established all further traffic will be SSH encrypted. I am not aware of proxies being contacted over https. An interesting feature might be QNetworkProxy::DefaultProxy which can use the system settings to determine the proxy server.
