 +**Client specific Log**
  
 +====== Introduction ======
 +
 +When diagnosing a problem, Samba developers are likely to request a level 10 log file.
 +
 +There are different reasons for creating client specific log files:
 +  * If the error appears only on specific clients and you won't change the config for all clients.
 +  * If you're running Samba with many clients level 10 logs can fill your disk space very fast and slow down your system.
 +
 +
 +====== Configuring client specific Log ======
 +----
 +
 +Create a new config file /​etc/​samba/​smb.conf.client-debug
 +<​code>​
 + ​[global]
 + # no log file size limitation
 + max log size = 0
 + # specific log file name
 + log file = /​var/​log/​samba/​log.%I
 + # set the debug level
 + log level = 10
 + # add the pid to the log
 + debug pid = yes
 + # add the uid to the log
 + debug uid = yes
 + # add the debug class to the log
 + debug class = yes
 + # add microsecond resolution to timestamp
 + debug hires timestamp = yes
 +</​code>​
 +
 +Add the following line to your smb.conf (/​usr/​local/​samba/​etc/​smb.conf) at the end of the global section:
 +<​code>​
 + ​include = /​etc/​samba/​smb.conf.client-%I
 +</​code>​
 +
 +To activate level 10 logging for e.g. client 10.12.2.70 create a symbolic link:
 +<​code>​
 + ln -s /​etc/​samba/​smb.conf.client-debug /​etc/​samba/​smb.conf.client-10.12.2.70
 +</​code>​
 +
 +You do not have to restart all of Samba. If the client 10.12.2.70 connects to your samba the smbd includes the /​etc/​samba/​smb.conf.client-10.12.2.70 config file and writes the debug information to /​usr/​local/​samba/​var/​log/​log.10.12.2.70. These changes will have no effect to other clients except 10.12.2.70. For additional clients you can simply create additional symlinks.
 +
 +For changing the log level temporary you can use smbcontrol runtime:
 +<​code>​
 + # set debug level for all smbd
 + ​smbcontrol smbd debug 10
 +
 + # set debug level for process with pid 12345
 + ​smbcontrol 12345 debug 10
 +
 + # request debug level for process with pid 12345
 + ​smbcontrol 12345 debuglevel
 +</​code>​
