When cron.daily runs, I get the following error related to sendmail
and logwatch:
/etc/cron.daily/0logwatch:
Can't exec "sendmail": Permission denied at /usr/sbin/logwatch line
1032, <TESTFILE> line 2.
Can't execute sendmail -t: Permission denied
The SE Linux error is:
type=SELINUX_ERR msg=audit(1280304906.187:42655):
security_compute_sid: invalid context
system_u:system_r:logwatch_mail_t:s0-s0:c0.c1023 for
scontext=system_u:system_r:logwatch_t:s0-s0:c0.c1023
tcontext=system_u:object_r:sendmail_exec_t:s0 tclass=process
Here is the relevant section of /usr/sbin/logwatch:
#Use mailer = in logwatch.conf to set options. Default should
be "sendmail -t"
#In theory this should be able to handle many different
mailers. I might need to add
#some filter code on $Config{'mailer'} to make it more robust. -mgt
open(OUTFILE,"|$Config{'mailer'}") or die "Can't execute
$Config{'mailer'}: $!\n";
my $mailto = $Config{"mailto_$Config{'hostname'}"};
$mailto = $Config{'mailto'} unless $mailto;
for my $to (split(/ /, $mailto)) {
print OUTFILE "To: $to\n";
}
print OUTFILE "From: $Config{'mailfrom'}\n";
print OUTFILE "Subject: Logwatch for $Config{'hostname'}
(${OStitle})\n";
The open statement (right under the comments) is line 1032.
Is this something that a bug needs to be opened on or is there a
context change on a file I can run to correct this? I'm not able to
use the SE Linux Troubleshooter because it generates the following
error (a bug to submit):
"Error while checking policy version."
Thanks.
