Netmon - a lightweight tray network monitor useful with netctl

Question

I rewrote it from Tidybattery.
Here is the code, and the AUR package.

Answer 1

Hello,
I have ported this little script to use Python 3 and PyQt4, because I found it usefull and I'm using razor-qt as my desktop. It's not finished (I have no wired connection to test), but works for my wireless connection.
#!/usr/bin/env python3
import os
import re
import sys
from subprocess import check_output
from PyQt4 import QtCore, QtGui
ENC = sys.getfilesystemencoding() or 'utf-8'
eth_re = re.compile(r'(inet6? [^ ]*) ', re.I)
def _get_interfaces(exclude_localhost=True):
if exclude_localhost:
return [x for x in os.listdir('/sys/class/net') if x != 'lo']
else:
return os.listdir('/sys/class/net')
def get_default_interface():
"""Returns the interface for the default route."""
ifaces = _get_interfaces()
out = check_output(['ip', 'route', 'list', 'scope', 'global']).decode(ENC)
for line in out.split('\n'):
if line.startswith('default'):
for iface in ifaces:
if ' {0} '.format(iface) in line:
return iface
def check_carrier(iface):
with open(os.path.join('/sys/class/net', iface, 'carrier')) as fp:
return fp.read().strip() == '1'
def get_wireless_status():
return check_output(['wpa_cli', 'status']).decode(ENC).strip()
def get_wired_status(iface):
out = check_output(['ip', 'addr', 'show', 'dev', iface]).decode(ENC)
res = []
for match in eth_re.finditer(out):
res.append(match.group(1))
return '\n'.join(res)
def get_interface_type(iface):
iface_type = 'wired'

iface_type = 'wireless'
return iface_type
class TrayIcon(QtGui.QSystemTrayIcon):

self.iface = None

self.setup()

if self.iface_type == 'wired':
self.setIcon(QtGui.QIcon.fromTheme('network-wired'))
self.setToolTip(get_wired_status(self.iface))
else:
self.setIcon(QtGui.QIcon.fromTheme('network-wireless'))
self.setToolTip(get_wireless_status())
if __name__ == '__main__':
app = QtGui.QApplication(sys.argv)
tray = TrayIcon()
tray.show()
sys.exit(app.exec_())

Edit: I think the better way is to get all the information from dbus. I try to implement it soon.
