At my company, some bonehead (not sure if it was maliciousness or just
a stupid customer), opened 60 simultaneous connections to our ftp
server and totally swamped our T1.This is the second or third time
this has happened recently.
So I'm looking for some way to limit the number of connection

Interestingly I did see GARP packets on the network with Em copper
connected to a 100base Switch(I don't have a gigabit Copper switch
rightnow).
You might want to try these things.

A related topic.Whenever an alias gets added to the interface, the
interface is reset.In my opinion this is uncalled for.The Interface
should be reset only when adding the first Ip address.As far as
interface is concerned Adding an IP address has no effect,except in the
first instance.My suggestion

em_ioctl() has a call to ether_ioctl() which in turn calls arp_ifinit().

When a UDP packet is read from a socket, the userland program can get the
destination IP address by using the IP_RECVDSTADDR socket option. This
returns the destination address as ancillary data in the msg_control member
of the msghdr structure passed to recvmsg().
I needed a way to get the desti
hi,
I had checked the kernel code of the freeBsd. In case of fxp port "
fxp_ether_ioctl" fucntional
will be called when we add a new address to an interface(using the if_ioctl
pointer from the
in_ifinit fucntion). And this fuction will inturn call the arp_ifinit
fucntion which sends the gratit

A priori, you can't. Looking in the Macintosh section will usually
assure you of getting something that is not Windows-specific, although
this is not a sufficient condition.

I haven't tried this, but I think the problem would go away
Could be attributed to the spanning tree in the switch.I have seen it
happening(especially with cisco switches).I bet you are not able to send
out any packet(Not just Garp).

Take your notebook to the USB-dealer :-) and ask if you can connect the
