Hi everyone,

Does anyone know how cmd/serv.go is called by SSH shell?  
[here](https://github.com/go-gitea/gitea/blob/main/cmd/serv.go#L42) It says `This command should only be called by SSH shell`. Does anyone know how SSH shell can call it? Does it mean we configure something in sshd config file so that it knows to call it?

I am just trying to understand how this is working: is it like for each SSH connection, a new gitea process is created?

Thanks!

yes, look into the authorized\_key file, and you’ll see that `gitea serv` is called. a full gitea process isn’t created, as the serv command is a lightweight connector that’ll interface with the running gitea process.
