Hi Simon, You have no guaranty that the SSH server will allow 1500 concurrent sessions, actually you're very likely to hit the user process number limit. You will need to serialize all these jobs into a limited amount of sessions, e.g. using GNU Parallels on the server side.
To answer your initial question, threading will not work because of the limitation you have mentioned. It is possible to solve this problem using ssh_poll objects and asynchronous programming. That's more complicated than with threads. Aris Le 26/09/2019 à 14:26, Simon Moselewski a écrit : > Problem is: You can only run one ssh_channel_request_exec per Channel. > So I need 1500 channels.
