Owner for /etc/bootptab

Jack C. Mahaffey — Mon, 11 Jul 2005 11:00:23 GMT

I'm seeing different owner settings for /etc/bootptab across several servers.

Some questions:

1 - Who should be the owner:group settings for this file? I'm seeing root:root and root:sys
2 - What background process reloads this file and what is the frequency? Is it possible that this process is resetting the permission when the file gets reloaded?

I am seeing consistency of -rw-r--r-- for the permissions for this file.

Thanks in advance....

Jack,

I'm seeing bin:bin on all my 11i boxes.

I just checked 2 of my 11.0 machines, 2 of my 11.11 machines and my 11.23 machine and they all show up with bin:bin ownership and permissions of 444 (-r--r--r--) for /etc/bootptab.

Hi,

I also have bin:bin on all my 11i boxes. But it may be different in case on different OS releases. It is used by bootp server which is probably used when you require to boot your other servers from this box which generally happens in case of ignite servers.

This file would be always read when bootpd daemon is started, or when some machine tries to boot off this server.

HTH,
Devender

I see that bin:bin is also used by /usr/newconfig/etc/bootptab. I'll change accordingly. It also lists -r--r--r-- permissions.

Assigned points... Thanks all. We're running 11.0.

bootptab is read by bootpd but only when it needs to start. bootpd is a daemon (when enabled in inetd.conf) which supplies automatic information to get some computer, router, JetDirect card, etc started. The permissions are not changed by bootptab (or any other kernel process). If the perms and/or ownership is being changed from the default values of 444 and bin:bin, then some cron job or other script is doing it.

Thanks Bill. I've reset it to bin:bin and -r--r--r-- and will monitor.
