Linux

Hi,

I'm using Linux 2.6 cross compiled for a embedded powerpc.
Earlier we were using busybox syslogd for logging the messages, but as the flexibilty is less, we decided to move to standard syslog.

Now I want to limit the size of the log file (/var/log/messages) to 128K.
I couldn't find any option in syslog.conf file to limit file size of log file, at the same time this option is present in busybox syslog.

Due to flash's size limitation I can't use cron or logrotate.
So, any one please provide a work around to limit the size of /var/log/messages or to make this file a circular one?
Any help is appreciated.

Thanks
Jay

use logrotate and its conf file, take a look here for examples.

Thanks, but I've clearly mentioned that I can't use logrotate.
May be I am looking for some kind of work around

hmm..
looks like there is no way to configure the log file size from syslogd

no there's not. you need logrotate which is not a huge application (~40k). if you're so tight on space, you'll probably find that rewriting a bunch of commands in assembly language with only the functionality that you desire and linking to standard C calls will produce much much smaller binaries.

I've done this myself, and things like cat (which is about 10k) I rewrote in 42 bytes with basic error checking. rewrite a bunch of simple commands like that and you'll have room for logrotate (which you may not want to rewrite).
