MAC address changes on every boot on fedora21 system?

0 votes
321 views

I am running a fully patched Fedora 21 system. We are trying to give it a long term lease in the DHCP server, but the MAC address sent changes on every boot. The MAC address seen at the DHCP server is not actually valid.

The DHCP server is like Win2008 Server R2.

I don't see that as possible unless the F21 machine has multiple NICs and the software is reassigning names on each boot. Not likely, but if it does, you could tell udev to always assign one of the NICs as a fixed name (em1, eth0, whatever) via a udev rule, then make sure that's the NIC which the dhclient runs on.

MySQL doesn't start automatically on system boot

according to several webpages, once installed you can set the mysqld service enable and start automatically when fedora starts.

for that you must run:

systemctl enable mysqld.service
systemctl start mysqld.service

however in my case this only start mysqld service for the running time. Once computer is restarted, mysqld does not start automatically.

Use firewall-cmd to filter by MAC address?

In a previous version of Fedora I had iptables rules of the form:

-A INPUT -p tcp --destination-port 25 -m mac --mac-source  AA:BB:CC:DD:EE:FF -j ACCEPT

in order to accept email only from selected local systems.

Ive just installed Fedora 20, and Im trying to implement the same kind of thing using:

 firewall-cmd

but Ive been unable to figure out how to do this. Any thoughts?
