Filesystem

Basic file operations, you can find there subset of python ‘os’ module related to files.

print h.fs.exists("/path/to/file")
h.fs.chown("/path/to/file", "root", "root")
h.fs.chmod("/path/to/file", "644")
h.fs.unlink("/path/to/file")

In additional there are methods to fetch / put file from / to remote system to / from local system.

h.fs.get("/path/to/remote/file", "/path/to/local/file/or/target/dir")
h.fs.put("/path/to/local/file", "/path/to/remote/file/or/target/dir")

There is one special method which allows transfer file between hosts.

h1.fs.transfer(
    "/path/to/file/on/h1",
    h2, "/path/to/file/on/h2/or/target/dir",
)

You can also mount devices.

with h.fs.mount_point(
    '//example.com/share', opts='ro,guest',
    fstype='cifs', target='/mnt/netdisk'
) as mp:
    h.fs.listdir(mp.target) # list mounted directory
    mp.remount('rw,sync,guest') # remount with different options
    h.fs.touch('%s/new_file' % mp.target) # touch file

Firewall

Allows to manage firewall configurarion. Check which firewall service is running on host (firewalld/iptables) and make configure this service.

h.firewall.is_active('iptables')
h.firewall.chain('OUTPUT').list_rules()
h.firewall.chain('OUTPUT').add_rule('1.1.1.1', 'DROP')

Network

It allows to manage network configuration.

print h.network.hostname
h.network.hostname = "my.machine.org"
print h.network.all_interfaces()
print h.network.list_bridges()

Package Management

It encapsulates various package managements. It is able to determine which package management to use. You can still specify package management explicitly.

Implemented managements:

• APT

• YUM

• DNF

• RPM

# install htop package using implicit management
h.package_management.install('htop')
# remove htop package using rpm explicitly
h.package_management('rpm').remove('htop')

System Services

You can toggle system services, it encapsulates various service managements. It is able to determine which service management to use in most cases.

Implemented managements:

• Systemd

• SysVinit

• InitCtl

if h.service('httpd').status():
    h.service('httpd').stop()
if h.service('httpd').is_enabled():
    h.service('httpd').disable()

Operating System Info

Host provide os attribute which allows obtain basic operating system info. Note that os.release_info depends on systemd init system.

print h.os.distribution
# Distribution(distname='Fedora', version='23', id='Twenty Three')

print h.os.release_info
# {'HOME_URL': 'https://fedoraproject.org/',
#  'ID': 'fedora',
#  'NAME': 'Fedora',
#  'PRETTY_NAME': 'Fedora 23 (Workstation Edition)',
#  'VARIANT': 'Workstation Edition',
#  'VARIANT_ID': 'workstation',
#  'VERSION': '23 (Workstation Edition)',
#  'VERSION_ID': '23',
#  ...
# }

print h.os.release_str
# Fedora release 23 (Twenty Three)

Storage Management

It is in PROGRESS state. Planed are NFS & LVM services.

Power Management

Give you possibility to control host power state, you can restart, poweron, poweroff host and get host power status.

Implemented managements:

• SSH

• IPMI

ipmi_user = User(pm_user, pm_password)
ipmi_params = {
    'pm_if_type': 'lan',
    'pm_address': 'test-mgmt.testdomain',
    'user': ipmi_user
}
h.add_power_manager(
    power_manager.IPMI_TYPE, **ipmi_params
)
# restart host via ipmitool
h.power_manager.restart()
