Question: I was trying to configure firewall using ‘system-config-firewall-tui‘ command on my CentOS VPS. However the command ended up with the below error message. I saw a similar post at techglimpse where you suggested to start messagebus service, but I don’t find that service in my machine. Can you tell me how to solve the below error?

[root@santu ]# system-config-firewall-tui
Traceback (most recent call last):
File "/usr/bin/system-config-firewall-tui", line 29, in <module>
import fw_tui
File "/usr/share/system-config-firewall/fw_tui.py", line 34, in <module>
import fw_nm
File "/usr/share/system-config-firewall/fw_nm.py", line 29, in <module>
import dbus
ImportError: No module named dbus
Solution:
Santu, you need to install ‘dbus‘ package and then start ‘messagebus‘ service.
# yum install dbus-python Loaded plugins: fastestmirror, presto Setting up Install Process Loading mirror speeds from cached hostfile * atomic: mirrors.thzhost.com * base: centos.excellmedia.net * extras: centos.excellmedia.net * updates: centos.excellmedia.net Resolving Dependencies --> Running transaction check ---> Package dbus-python.x86_64 0:0.83.0-6.1.el6 will be installed --> Finished Dependency Resolution
Once installed, start ‘messagebus‘ service as below:
# service messagebus start
Now try launching ‘system-config-firewall-tui‘ command and it should work.
