[jira] [Comment Edited] (GUACAMOLE-600) Allow specifying connection timeout

["Mike Jumper (Jira)" <ji...@apache.org>]

----------------------------------------------------------------

[~vnick]: I've been doing some fiddling, and the issue seems related to the introduction of that {{fcntl()}} call setting the socket in non-blocking mode so we can have a connect timeout. I tried restoring the original flags at the end (under the assumption that things are failing because the caller is not expecting to receive a non-blocking socket), but that second call to {{fcntl()}} fails with {{EBADF}}. Removing _all_ calls to {{fcntl()}} such that the socket is a blocking socket "fixes" the issue (but presumably breaks the timeout).

> This came up in a mailing list discussion, specifically related to SSH connections, but seems like it would be useful across all of the protocols to allow the connection to specify the timeout in making the connection.  For environments where connections are expected to happen rapidly this can reduce delays if something is wrong; for environments that may experience larger delays it can avoid errors when the connection is expected to take a longer amount of time to establish.
