Net::CLI::Interact::Transport::SSH − SSH based CLI connection
This module provides a wrapped instance of an SSH client for use by Net::CLI::Interact.
On Windows platforms you must download the "plink.exe" program, and pass its location to the library in this parameter. On other platforms, this defaults to "ssh" (openssh).
Based on the
"connect_options" hash provided to
Net::CLI::Interact on construction, selects and formats
parameters to provide to "app" on the command
line. Supported attributes:
host (required)
Host name or IP address of the host to which the SSH application is to connect. Alternatively you can pass a value of the form "user@host", but it’s probably better to use the separate "username" parameter instead.
username
Optionally pass in the username for the SSH connection, otherwise the SSH client defaults to the current user’s username. When using this option, you should obviously only pass the host name to "host".
ignore_host_checks
Under normal interactive use "openssh" tracks the identity of connected hosts and verifies these identities upon each connection. In automation this behaviour can be irritating because it is interactive.
This option, enabled by default, causes "openssh" to skip or ignore this host identity verification. This means the default setting is less secure, but also less likely to trip you up. It is equivalent to the following:
StrictHostKeyChecking=no
UserKnownHostsFile=/dev/null
CheckHostIP=no
Pass a false value to this option to disable the above and return "openssh" to its default configured settings.
opts
If you want to pass any other options to openssh on its command line, then use this option, which should be an array reference. Each item in the list will be passed to "openssh", separated by a single space character. For example:
$s−>new({
# ...other parameters to new()...
connect_options => {
opts => [
'−p', '222', # connect to non−standard port on
remote host
'−o', 'CheckHostIP=no', # don't check host IP in
known_hosts file
],
},
});
reap
Only used on Unix platforms, this installs a signal handler which attempts to reap the "ssh" child process. Pass a true value to enable this feature only if you notice zombie processes are being left behind after use.
