I make it.

I have a little script to start fetchmail, which is activated in
rc.local. It runs perfectly when started from a root login; but it
fails when started from rc.local.

Here is the info:
=========================== Scripts Start
===========================
$ more rc.local fetchmail-start
::::::::::::::
rc.local
::::::::::::::
#!/bin/sh
#
# This script will be executed *after* all the other init
scripts.
# You can put your own initialization stuff in here if you
don't
# want to do the full Sys V style init stuff.

# Fork a script that will start fetchmail for jonrysh in a
few seconds
/etc/rc.d/fetchmail-start

touch /var/lock/subsys/local
::::::::::::::
fetchmail-start
::::::::::::::
#!/bin/sh
#
# Start fetchmail for jonrysh

su jonrysh -c 'sleep 5; fetchmail'

=========================== Messages Start
===========================
Fetchmail emits the following error message and fails:
fetchmail: open: /home/jonrysh/.fetchmailrc: Permission
denied

What's happening? How can it be fixed?


The perms on /home/jonrysh/.fetchmailrc need to be 600, with
ownership
given to jonrysh:jonrysh

Everything is as you recommend. Note that the scheme works when
invoked
from a command window running a shell as root, but not from the init
script.


You could also start it without the su by adding it to your own
crontab:
@reboot sleep 30& fetchmail

Thanks, I'll try this. But I'd still like to know what's the reason
for
the permission failure when running out of rc.local . SELinux
issues?


----
this works for me (in rc.local)...

/bin/su - craig -c '/usr/bin/fetchmail'&

I tried it, and now things are worse than before. The startup script
now reads:
#!/bin/sh
#
# Start fetchmail for jonrysh

su - jonrysh -c 'sleep 5; fetchmail'

Now there's an additional error in boot.log:
...
Starting atd: [
OK ]
Error opening display!
fetchmail: open: /home/jonrysh/.fetchmailrc: Permission denied

The display did actually start OK after a short delay. It's a mystery
to me.

Thanks to all - jon





Check to see if there are SELinux AVC messages in
/var/log/audit/audit.log

# grep fetchmail /var/log/audit/audit.log

Also instead of using su, use runuser (Same thing except runuser does
not use the pam stack.)
