A customer appears to have drastically misunderstood our instructions for connecting to our WAN. He set his PC IP address to the same as one of the bridges. This caused much confusion on the network, to put it mildly. He called to complain about the poor performance of the network he ruined, then made himself unavailable for phone calls so it couldn't be fixed.
Even blocking his MAC address didn't help. The bridging problem happens in midair, nowhere the server can control. If I could at least get into the bridge, I could reconfigure it to a different IP and allow traffic again...
So, on the server, I tried this:
This succeeded in forcing the server to talk to the bridge, not to him. I was then able to get into the bridge's web interface and change its IP from there. From there it was easy.

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...

I'm running an arp -an on a Solaris 10 box. We're using IPMP. One of the systems is not able to see a host on the same network. The only difference between the two systems (one is having a problem, the other isn't) at least so far is the output of arp:

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... (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:
In my opinion, the best possible... (2 Replies)
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)
