|
||
|
|
|
||
|
|

|
||
|
|
|
||
|
|
This plugin uses the following configuration variables:
|
||
|
|
|
||
|
|
[samba]
|
||
|
|
user root
|
||
|
|
env.smbstatus /usr/bin/smbstatus
|
||
|
|
env.ignoreipcshare 1
|
||
|
|
|
||
|
|
Usually "smbstatus" requires to be run as root (see "user root" above).
|
||
|
|
|
||
|
|
Environment variables:
|
||
|
|
|
||
|
|
* smbstatus: path to "smbstatus" executable
|
||
|
|
(default: search PATH and fall back to /usr/bin/smbstatus)
|
||
|
|
* ignoreipcshare: set this variable to any non-empty value to ignore IPC$ when counting shares.
