capistrano remote requirements

i am trying to deploy PHP app with capistrano, but i can't find what ssh commands exactly capistrano needs to have allowed on remote server.

my remote host allows t开发者_运维知识库his ssh channels:

• SFTP/SCP
• rsync

$ pwd called via SSH there returned nothing:

pwd

WinSCP: this is end-of-file:0

I know Capistrano needs more, but can't find what exactly.

If you're able to ssh into you machine and run the "sh" command, things should be fine. There's a list of requirements here:
