# Access to methods using '$anvil->System->X'.
#
# Example using 'system_call()';

=head2 activate_lv
This takes a logical volume path and tries to activate it. If it is successfully activated, C<< 1 >> is returned. If the activation fails for any reason, C<< 0 >> is returned.
my $activated = $anvil->System->activate_lv({path => "/dev/foo/bar"});
Parameters;
=head3 path (required)
This is the full path to the logical volume to activate.

=head2 call
This method makes a system call and returns the output (with the last new-line removed) and the return code. If there is a problem, 'C<< #!error!# >>' is returned and the error will be logged.
my ($output, $return_code) = $anvil->System->call({debug => $debug, shell_call => "host_name"});
Parameters;
=head3 background (optional, default '0')
If set to C<< 1 >>, the program will be started in the background and the C<< Proc::Simple >> handle will be returned instead of the command's output.
=head3 line (optional)
This is the line number of the source file that called this method. Useful for logging and debugging.
=head3 redirect_stderr (optional, default '1')
By default, C<< STDERR >> is redirected to C<< STDOUT >>. If this is set to C<< 0 >>, this is disabled.
=head3 secure (optional)
If set to 'C<< 1 >>', the shell call will be treated as if it contains a password or other sensitive data for logging.
=head3 shell_call (required)
This is the shell command to call.
=head3 source (optional)
This is the name of the source file calling this method. Useful for logging and debugging.
=head3 stderr_file (optional)
B<NOTE>: This is only used when C<< background >> is set to C<< 1 >>.
If set, the C<< STDERR >> output will be sent to the corresponding file. If this isn't a full path, the file will be placed under C<< /tmp/ >>.
=head3 stdout_file (optional)
B<NOTE>: This is only used when C<< background >> is set to C<< 1 >>.
If set, the C<< STDOUT >> output will be sent to the corresponding file. If this isn't a full path, the file will be placed under C<< /tmp/ >>.
=head3 timeout (optional, default '0')
If set, a timeout will be placed on the call. If the call takes more than C<< timeout >> seconds, the call will fail and the C<< return_code >> will be C<< 124 >>.

=head2 change_shell_user_password
This changes the password for a shell user account. It can change the password on either the local or a remote machine.
The return code will be C<< 255 >> on internal error. Otherwise, it will be the code returned from the C<< passwd >> call.
B<< Note >>; The password is salted and (sha-512, C<< $6$<salt>$<hash>$ >>
Parameters;
=head3 new_password (required)
This is the new password to set. The user should be encouraged to select a good (long) password.
=head3 password (optional)
If you are changing the password of a user on a remote machine, this is the password used to connect to that machine. If not passed, an attempt to connect with passwordless SSH will be made (but this won't be the case in most instances). Ignored if C<< target >> is not given.
=head3 port (optional, default 22)
This is the TCP port number to use if connecting to a remote machine over SSH. Ignored if C<< target >> is not given.
=head3 remote_user (optional, default root)
If C<< target >> is set and we're changing the password for a remote user, this is the user we B<< log into >> the remote machine as, B<< not >> the user whose password we will change.
=head3 target (optional)
This is the IP address or (resolvable) host name of the target machine whose user account you want to change the password
=head3 user (required)
This is the user name whose password is being changed.

=head2 check_ram_use
This is meant to be used by daemons to check how much RAM it is using. It returns an anonymous array with the first value being C<< 0 >> if the in-use RAM is below the maximum, and C<< 1 >> it the in-use RAM is too high. The second value is the amount of RAM in use, in bytes. If the program is not found to be running, C<< 2, 0 >> is returned.

program => $THIS_FILE,

Parameters;
=head3 program (required)
This is generally C<< $THIS_FILE >>. Though this could be used to check the RAM use of other programs.
=head3 max_ram (optional, default '1073741824' (1 GiB))
This is the limit allowed. If the in-use RAM is greater than this amount, an alert will be generated and sent.

=head2 check_ssh_keys
This method does several things;
1. This makes sure the users on this system have SSH keys, and creates the keys if needed.
2. It records the user's keys in the C<< ssh_keys >> table.
3. For the dashboard machines whose databases this host uses, it adds their host machine public key (SSH fingerprint) to C<< ~/.ssh/known_hosts >>.
4. If this machine is a node or DR host, it sets up passwordless SSH between the other machines in the same Anvil! system.
This works on the C<< admin >> and C<< root >> users. If the host is a node, it will also work on the c<< hacluster >> user.
B<< Note >>: If a machine's fingerprint changes, this method will NOT update C<< ~/.ssh/known_hosts >>! You will see an alert on the Striker dashboard prompting you to clear the bad keys (or, if that wasn't expected, find the "man in the middle" attacker).
This method takes no parameters.

=head2 collect_ipmi_data
This takes an C<< ipmitool >> command (for access, not including ending command or password!) and calls thae target IPMI BMC. The returned data is collected and parsed.
If failed to access, C<< 1 >> is returned. If there is a problem, C<< !!error!! >> is returned. If data is collected, C<< 0 >> is returned.
Recorded data is stored as:
ipmi::<host_name>::scan_ipmitool_sensor_name::$sensor_name::scan_ipmitool_value_sensor_value
ipmi::<host_name>::scan_ipmitool_sensor_name::$sensor_name::scan_ipmitool_sensor_units

ipmi::<host_name>::scan_ipmitool_sensor_name::$sensor_name::scan_ipmitool_sensor_low_warning
parameters;
=head3 host_name (required)
This is the name used to store the target's information. Generally, this should be the C<< host_name >> value for the target machine, as stored in C<< hosts >>.
=head3 ipmitool_command (required)
This is the C<< ipmitool >> command used to authenticate against and access the target BMC. This must not contain the password, or the command to run on the BMC. Those parts are handled by this method.
=head3 ipmi_password (optional)
If the target BMC requires a password (and they usually do...), the password will be written to a temporary file, and C<< -f <temp_file > >> will be used as part of the final C<< ipmitool >> command call. As soon as the call returns, the temp file is deleted.

=head2 configure_ipmi
This uses the host information along with the Anvil! the host is in to find and configure the local IPMI BMC.
If this host is not in an Anvil!, or if the host is in an Anvil!, but no IPMI BMC was found, or any other issue arises, C<< 0 >> is returned. If there is any problem, C<< !!error!! >> will be returned.
If a BMC is found and configured, the C<< fence_ipmilan >> call used to check the status is stored in C<< hosts >> -> C<< host_ipmi >>, and the same string is returned.
B<< NOTE >>: The password used to set the IPMI BMC access is included both in the database table and the returned string.
Parameters;
=head3 dr (Optional, default 0)
This indicates that a DR host is being configured. If used, C<< manifest_uuid >> is ignored.
=head3 manifest_uuid (Optional, default sys::manifest_uuid)
The C<< manifests >> -> C<< manifest_uuid >> used to pull out configuration data. This is required, but in most cases, it can be determined if not passed.
If not passed, C<< sys::manifest_uuid >> is checked. If this is set, it is used. If this isn't set either, the call will fail.

=head2 pids
This parses C<< ps aux >> and stores the information about running programs in C<< pids::<pid_number>::<data> >>. If called against a remote host, the data is stored in C<< remote_pids::<pid_number>::<data> >>.
Optionally, if the C<< program_name >> parameter is set, an array of PIDs for that program will be returned.
Parameters;
=head3 ignore_me (optional, default '0')
If set to C<< 1 >>, the PID of this program is ignored.
=head3 program_name (optional)
This is an option string that is searched for in the 'command' portion of the 'ps aux' call. If this string matches, the PID is added to the array reference returned by this method.
=head3 password (optional)
If you are testing IPMI from a remote machine, this is the password used to connect to that machine. If not passed, an attempt to connect with passwordless SSH will be made (but this won't be the case in most instances). Ignored if C<< target >> is not given.
=head3 port (optional, default 22)
This is the TCP port number to use if connecting to a remote machine over SSH. Ignored if C<< target >> is not given.
=head3 remote_user (optional, default root)
If C<< target >> is set, this is the user we will use when logging in to the target machine.
=head3 target (optional)
This is the IP address or (resolvable) host name of the target machine to test the IPMI connection from.

=head2 stty_echo
This turns echo off (for password prompts, for example) and back on again. It does so in a way that a SIGINT/SIGKILL can restore the echo before the program dies.
B<< Note >>: Calling C<< on >> before C<< off >> will result in no change. The C<< off >> stores the current TTY in C<< sys::stty >> and uses the value in there to reset the terminal. If you want to change the terminal, you can set that variable manually then call C<< on >>, though this is not recommended.
Parameters;

This is set to C<< on >> or C<< off >>, which enables or disables echo'ing respectively.

=head2 test_ipmi
This tests access to an IPMI interface, either locally or from a remote client. This method will automatically shorten the passed-in IPMI password to 20 bytes if the existing password is longer and fails. If the 20 byte password also fails, it will try a third time with a 16 byte password.
If a working connection is found, the C<< fence_ipmilan >> command that worked will be returned (including the password that worked).
B<< Note >>: This test uses the C<< fence_ipmilan >> fence agent. This must installed and available on the remote machine (if testing remotely).
Parameters;
=head3 ipmi_password (required)
This is the IPMI user password to use for the IPMI user. It will be shortened to 20 bytes and 16 bytes if necessary.
B<< Note >>: The password will be escaped for the shell inside this method. Do NOT escape it before sending it in!
=head3 ipmi_target (required)
This is the IP or (resolvable) host name of the IPMI BCM to be called.
=head3 ipmi_user (required)
This is the IPMI user to use when trying to log into the IPMI BMC.
=head3 lanplus (optional, default "no-yes")
This determines if LAN Plus is tried when connecting to the IPMI BMC. This is often vendor-specific (some vendors _usually_ use it, others _usually_ don't). If you know for sure which your BMC needs, you can set it. If you aren't sure, but think you know, you can have it try both, either using or not using LAN Plus initially.
This can be set to;
* C<< yes >> - use LAN Plus
* C<< no >> - don't use LAN Plus
* C<< yes-no >> - Try both, using LAN Plus, then trying without.
* C<< no-yes >> - Try both, trying without LAN Plus first, then trying with it.
B<< Note >>: If there is an existing entry in C<< hosts >> -> C<< host_ipmi >>, that will possibly change this value. If C<< --lanplus >> is found, and this is set to C<< no >> or C<< no-yes >>, it will be changed to C<< yes-no >>. Reversed, if C<< --lanplus >> is NOT found, and this was set to C<< yes >> or C<< yes-no >>, it will be changed to C<< no-yes >>. As such, you may want to verify the returned shell command to see if LAN Plus is needed or not, regardless of how this is set.
=head3 password (optional)
If you are testing IPMI from a remote machine, this is the password used to connect to that machine. If not passed, an attempt to connect with passwordless SSH will be made (but this won't be the case in most instances). Ignored if C<< target >> is not given.
=head3 port (optional, default 22)
This is the TCP port number to use if connecting to a remote machine over SSH. Ignored if C<< target >> is not given.
=head3 remote_user (optional, default root)
If C<< target >> is set, this is the user we will use when logging in to the target machine.
=head3 target (optional)
This is the IP address or (resolvable) host name of the target machine to test the IPMI connection from.

=head2 _load_specific_firewalld_zone
This takes the name of a service (with or without the C<< .xml >> suffix) and reads it into the C<< $anvil->data >> hash.
Data will be stored as:
* C<< firewalld::zones::by_name::<service>::name = Short name >>
* C<< firewalld::zones::by_name::<service>::tcp = <array of port numbers> >>
* C<< firewalld::zones::by_name::<service>::tcp = <array of port numbers> >>
* C<< firewalld::zones::by_port::<tcp or udp>::<port number> = <service> >>
The 'C<< service >> name is the service file name, minus the C<< .xml >> suffix.
If there is a problem, C<< !!error!! >> will be returned.
Parameters;
=head3 service (required)
This is the name of the service to read in. It expects the file to be in the C<< path::directories::firewalld_services >> diretory. If the service name doesn't end in C<< .xml >>, that suffix will be added automatically.
