There is a service for the netconsole under CENTOS, and I have used the same. For this, I did the following. Target system means where we load (insert) the driver with debug messages. Host System means where we see the debug messages i.e. received debug messages from target system. Target System Configuration Open the /etc/sysconfig/netconsole file and modify the following variables. a) LOCALPORT - keep the default port number only b) SYSLOGADDR - This is the host (remote) system IP address c) SYSLOGPORT - keep the default port number only d) SYSLOGMACADDR - This is the host system MAC address Then, save the file and exit. Just run the netconsole service with the following command. # service netconsole restart Host System Configuration Just run the syslogd service with the following command to log the target system debug messages. However, this service starts by default. # service syslog restart This is working fine for SINGLE thread. If the driver has two threads, then I am missing the debug messages from one of the threads. For example, in the USB mass storage driver, I am getting the messages only when I insert the module (modprobe -a usb_storage). But, when I insert the actual mass storage device then the debug messages in STORAGE_PROBE function was not logged into the host machine /var/log/messages file where as I am able to see the same (STORAGE_PROBE function) debug messages in the target system /var/log/messages. Please let me know if I missed any configuration settings.
