syslog function try to write to /dev folder

[johnhelen]

hello

In a perl script for a cronjob, there is a function:

sub _write_sys_log {
my $seft = shift;
my $level = shift;
my $string = shift;
syslog($level, '%s', "$string");
}

This function is called from other function. I think that the function above should write logs to syslog file. However, it tries to write logs to /dev/consolog. As /dev/consolog is own by root, so it cannot write logs to this file. Therefore, it throws an error.

My question is how I can write these logs to syslog file. I am not good in perl and I am not the person who wrote this script, so please have some suggestions

Many thanks

I am going to take a guess here and say that in the script you are looking at, that they are using the Sys::Syslog module from CPAN. I say that because that is where I see the syslog() function defined.

That said, you should read that link as they probably have the open() function defined and pointing to the file it is trying to write to.

Also, I am guessing that you mean that this script is "run by the crontab". In that case, the reason they have this pointing to a root permission log is because when crontab jobs get run, it is the root user that is doing the executing.

Thank you, you right

I check and there is openlog call as:

openlog('NEW', '', 'local2);

Is it correct

Thanks

You may want to read the functions part of the documentation. The first function is openlog() which it says has 3 parameters, where yours only has 2.

Unfortunately I haven't used this module and am unfamiliar with any caveats it may have, but it does look like that needs to be fixed.

Thanks for very quick reply
I also I discover that the "local2" facility (inside openlog function) is not in the /etc/syslog.conf file. Do you think that is the problem too ???

I would say that is the problem. I would track it down and see if the facility is modifiable.

"I would track it down and see if the facility is modifiable"

You mean that I should add one entry into the syslog.conf

local2.* /var/logs/syslog

So the log message will be written into syslog file ?

Many thanks for great help

Yes, that's exactly what I mean. Hope it works for you!
