Technically, it might make a bit more time to bubble the initial packets through NATs and stuff, but if you use poll later in your application, you can specify your timeout already. > > Will this work as intended? > > int conn_timeout = 5; // custom connect timeout > ssh_options_set(session, SSH_OPTIONS_TIMEOUT, conn_timeout); > ret = ssh_connect(session); > /* handle ret */ > ssh_options_set(session, SSH_OPTIONS_TIMEOUT, 0); > > Does SSH_OPTIONS_TIMEOUT 0 set the default behavior? > Yes, calling this will set the internal value to 0 and this is interpretted as default, 10s timeout so your suggestion should work.
