Increase system.log size?

[cypher1024]

Hey guys,
First I want to say thanks for NAS4Free. I had been running FN 0.7 up until a few days ago (and thought I'd be using it forever) because I tried FN8 on a test machine and didn't like it, but I didn't know about N4F.

I was just wondering how I would go about increasing the maximum size of system.log. I have an IP camera that uploads images to my N4F machine via FTP. Unfortunately, every time it uploads an image it generates a proftpd "login successful" message. It doesn't take long before the entire log is filled with these messages. I have NAS4Free installed on a 1TB hard drive, so free space isn't going to be a problem.

I tried looking for a config file that specified the maximum size of log files, but came up with nothing.

I think you will find it under the tab system|advanced|rc.conf

Default is set to 32M

Thanks for the quick reply!!

I've increased it from 32m (4MB) to 64M. Could increasing it that much cause any problems?

Edit: I just rebooted and system.log still seems to be stuck at 256kB

Edit 2: I've done some research and testing and it seems that varsize only affects embedded installs. /var can grow much larger than varsize on full installs.

If you have the embeded it will not work as it goes back to default after reboot

It's a full install, and I double-checked that the change persisted.
After the reboot, /var is only at about 2.7MB yet the system.log file is still capped at 256kB.

Edit: after some more research, it seems that in NAS4Free (and I guess FreeNAS too), syslogd has been patched with clog.
Knowing that, I did a search for "clog" and found a file by that name in /etc/rc.d/.
Inside is this gem:

Code: Select all

# Generate circular logfiles if necessary
if [ ! -e "${clog_logdir}/system.log" ]; then
	clog -i -s 262144 "${clog_logdir}/system.log"
fi

Ahh, the mythical 256kB figure!

I modified it to 8388608 (8MB) and saved the file, then I executed the command:

Code: Select all

clog -i -s 8388608 "/var/log/system.log"

The system log went blank (when viewed from the webUI (which I expected), but I freaked out when new events weren't being added. I viewed system.log in nano, and it was just 8MB of ^@^@^@^@^@^@^@^@^@^@!!

Thankfully, a reboot fixed it and now it seems to be working as it should!
