[stunnel-users] Stunnel log file limit

[mehmet ozisik]

Hi,

I would like to ask some questions regarding stunnel logging which I could not find answer with googling.

1) what is the limit of stunnel log file (can we define this)?

2) If there is a limit, when the limit is reached does it remove the filled file and starts with the same name an empty log file?

Regards

Mehmet

Log rotation is already on my TODO list:

Hi Michal,

thanks for the fast response.

But in to do list it seems that rotate is for windows.Also seems never be supported.

I mean for linux also stunnel's self log rotation.

Could you please inform me?

Hi Michal,

I am running stunnel on a minimal system which has limited flash size, so using extra binary is expensive for me.

I know those mechanisms there are on linux. But I am asking something like this within stunnel codes :

While stunnel running it will check also log size, then when stunnel realized the log size limit (which is defined in conf file for example) reached it will re-open the log file in write mode (by the way old info will be deleted).

Regards

I did some testing, and this is what I came up with that seems to
work. Original had just tried deleting the log file, but then later
usage of stunnel would not add to the file. truncate seems to keep
the file in a state were stunnel will continue. I used 473 since that
is the size of my stunnel.log after an original startup. I also just
used 50000 as a limit size for no real reason.

if [ `ls -l /var/log/stunnel.log | awk '{print $5}'` -gt 50000 ] ; then
truncate -c -s 473 /var/log/stunnel.log
fi

Don't know if you current setup has awk or truncate, so it might
also add a little size. Probable other ways to get the file size, and
you could then run it with cron, or add a sleep option, and have it
call itself.
