I have set logging to high.

I am not seeing any log messages.

I do see the empty ufw.log file.

No messages in dmesg

  • Check this in the terminal "Sudo Ufw status" if the yfw is enabled you may have a problem with loging events – Prasad RD Mar 16 '12 at 9:09
  • status says: logging high, so ufw thinks logging is set correctly. Any clues on how I can proceed? – sureshvv Mar 16 '12 at 9:41

The log files are in:

/var/log/

To get a list of UFW related logs run the following at the command line:

ls /var/log/ufw*

Your results should appear like this:

~$ ls /var/log/ufw*
/var/log/ufw.log    /var/log/ufw.log.2.gz  /var/log/ufw.log.4.gz
/var/log/ufw.log.1  /var/log/ufw.log.3.gz

If you do not have logs there you may want to double check the status and settings for UFW.

sudo ufw status verbose

You should get a result like this:

~$ sudo ufw status verbose
Status: active
Logging: on (low)
Default: deny (incoming), allow (outgoing)
New profiles: skip

If logging is off then you need to turn it on by running the following command:

sudo ufw logging low

If you do not have any log files then you can check to see if rsyslogd is running by typing:

sudo service rsyslog status

You should get a result as follows:

~$ sudo service rsyslog status
rsyslog start/running, process 991

If it does not show that it is running you can try to start the service:

sudo service rsyslog restart

  • rsyslog was running. I restarted. logging level already set to high. Still no joy! ufw.log is empty. What events are logged? Will attempt to access any port that has a DENY rule be logged? – sureshvv Mar 17 '12 at 3:03

last time i checked the log file for ufw it was in the

/var/log/ufw.log

folder, with a lot of other files

  • /var/log/ufw.log is an empty file - not a folder for me – sureshvv Mar 16 '12 at 8:40
  • No, what he mentioned there is the log folder!. Anyone knows it isn't a folder if it ends with an extension :-) – Prasad RD Mar 16 '12 at 9:47

    not true of the .d extension...and it's a 1 rep asker...so maybe not 'Anyone' – RobotHumans Mar 16 '12 at 9:55

Just to add to @cprofitt's answer, I had an issue where UFW was showing:

sudo ufw status verbose
Status: active
Logging: on (low)

But it was not logging. I went through several gyrations, including disable/re-enabling ufw. Checking rsyslog conf, restarting rsyslog. All without any positive results. Still nothing going to the logfile.

I did a sudo ufw logging low and logs started growing once again. So ufw was obviously in some state where it would not write to the logs.

I deleted the empty /var/log/ufw.log file, restarted and ufw began logging.
