16.4.19.1 Defining a remote connection tool

Several remote access tools are already defined in GPS: ssh, rsh, telnet and plink. It is possible to add other tools, using the node remote_connection_config.

The attributes for this node are:

name (string) (mandatory)
The name of the tool. This name does not necessarilly correspond to the command used to launch the tool.

The following children are defined:

start_command (mandatory)
The command used to launch the tool. This tag supports the use_pipes attribute. This attribute selects on Windows the way GPS will launch the remote tools, and can take the following values:
true
use pipes to launch the tool.
false (default)
use a tty emulation, which is a bit slower but allow password prompts retrieval with some tools.
Note that this argument has effects only on Windows platforms.
start_command_common_args (optional)
The common arguments that are provided to the tool.
start_command_user_args (optional)
The arguments used to define a specific user during connection.
user_prompt_ptrn (optional)
A regular expression, used to catch user name prompts from the connection tool. If undefined, a default regular expression is used.
password_prompt_ptrn (optional)
A regular expression, used to catch password prompts from the connection tool. If undefined, a default regular expression is used.
passphrase_prompt_ptrn (optional)
A regular expression, used to catch passphrase prompts from the connection tool. If undefined, a default regular expression is used.
use_cr_lf (optional)
Boolean value, used to tell GPS if the connection tool requires CR+LF characters to determine an end of line, or if LF is sufficient. Set to false by default.
extra_ptrn (optional)
Complex child. Used to catch extra prompts from the connection tool, other than password, passphrase or usename prompts. This tag has an attribute auto_answer telling if GPS automatically answers to this prompt, or ask the user. If auto_answer is true, then this tag needs an answer child, whose value is used for the answer. If auto_answer is false, then this tag needs a question child, whose value is used as question to the end user.
