<div dir="ltr">Running 4.1.1-p1 on a physical RHEL6 system, I've had an intermittent issue recently with dhcp offers not being responded to. This started late last week, and was first resolved by rebooting the system; restarting dhcpd nor disabling iptables resolved the problem. Informs and Acks seemed to work fine, but releasing and renewing did not work.<div>
<br></div><div>The problem popped back up again today, and reboots did not resolve the problem; I wound up creating a VM with CentOS5 and dhcpd 3.0.5 on a VMWare ESXi server and things seem to be back up and running for now. </div>
<div><br></div><div>Has anyone ever run into this issue on an intermittent basis before? If this was a fresh install that would be one thing, but this server has been in place for over a year and this is the first indication of trouble. Restarting dhcpd nor disabling iptables resolved the problem, nor did a reboot. What would change for clients to stop responding to offers (or for offers to stop getting to them)?</div>
<div><br></div><div>Any advice would be appeciated.</div><div><br></div><div><br></div><div>Thanks,</div><div><br></div><div>Scott</div></div>
