how many reverse ssh tunnel can connect to ubuntu server?is there any firewall limit or does it take a resource of my server?
I am using below command to tunnel from client to my server or client:
ssh -fNTR PORT:localhost:22 USER@SERVER_IP
(each PORT is different for each client)
and then on server i am using this command:
ssh CLIENT_USER@localhost -p PORT
In this way how many client can connect to my server simultaneously?
