My coding is available at svn co http://www.xypron.de/svn/x2go/x2goclient/branches/proxy/ The changes in sshmasterconnection.* and connectionwidget.* are complete to my understanding. In onmainwindow I have only treated one of three entrypoints to sshmasterconnection. E.g. LDAP is not proxy enabled yet. In onmainwindow the proxy password field I introduced possibly should only be shown if a proxy is used and a login provided. Best regards HeinrichHello Heinrich, I've checked your code and it looks good for me. I'll include it in master branch soon. You have developed support for HTTP proxy. I'm working now on a little more complex case - SSH proxy with password/public key authentication. In the future user should be able to choose between HTTP and SSH proxy.
Alex, I would be very pleased if you could reuse the sshproxy options available in PyHoca-GUI:
usesshproxy (Bool) sshproxyuser (String) sshproxykeyfile (Pathname) sshproxyhost = (String, Host:Port) (example: myhost.somedomain.tld:32032)sshproxytunnel (String) (example: 127.0.0.1:22234:<ip-or-host-behind-proxy>:22)
I have a one notice. In your case HTTP protocol is used for proxy. It is mean, that user name and password will be transmitted unencrypted. It can follow to security issues. Can you think about HTTPS support? This should be not very difficult, as Qt already supports SSL. You can check code of HttpBrockerClient class in X2Go Client, which can use HTTPS connections.
HTTP should not be available... only HTTPS.
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. Such distributions should be also supported by X2Go Client.
Let me know what the minimum of a version of libssh is that you need. I will see that our Debian and Ubuntu archives have the needed version available (unless the distro itself has the proper version).
