Subject: RE: [EXTERNAL] how to migrate an openldap server to a new linux server

Because port 22 is not open, I can't ssh or rlogin to the server. only can run ldapsearch such client commands. nmap to the server only see port 389 and 636 open. I don't know how the server owner maintain, startup/stop the server.
