About a week ago a customer hooked up a wireless router backwards to our network, causing it to serve incorrect DHCP addresses to some of them. Our networks are mostly statically assigned so this didn't cause as much damage as it might have, but now, over a week later, I still have incomplete 192.168.10.x entries stuck in the ARP table:
arp -d cannot delete the incomplete entries, and they won't go away. I suppose they're harmless but I'd get rid of them if I could. Is there any better way than a reboot?
Dear all,
We are testing two of our servers for mq series connectivity. The scenario is, when one machine is shutting down it's services there are some scripts that do a dns update, which removes the ip address and relates it to the ip address of the other node on our dns server, and the update...

Man page of netlink says:

Is it possible to monitor arp table using Netlink? or it's just for manipulating? (1 Reply)

Hi, I'm trying to find a way to protect my network against arp spoofing.
What it is:
An attacker sends fake arp packets in the network, identifying himself as the router. All network traffic is then redirected to this attacker.
How to protect myself:

Hello,
I have 2 clients with Unix installed.
host1: eth0 (192.168.5.10) & eth1 (192.168.10.10)
host2: eth0 (192.168.10.20)
I've connected host1-eth1 to host2-eth0. host1-eth0 isn't connected.
I started 'tcpdump' on wonder that host2 got ARP requests for 192.168.5.10.
Any idea why host1... (2 Replies)

Lire::Firewall::IpfilterDlfConverter - convert ipf (ipmon) logs to firewall DLF
DESCRIPTION
Lire::Firewall::IpfilterDlfConverter converts Ipfilter logs into firewall DLF format. Input for this converter is the standard ipf syslog
log file as produced by ipmon. IP Filter is shipped with FreeBSD, OpenBSD (up to 2.9) and some other OS's.
EXAMPLE
A ipfilter logfile which looks like
