Anyone Ported Cisco Discovery Protocol? (CDP)

Hi,

Has anyone ported CDP to Linux? I'd like to get it rather than having to

write it myself.

Thanks,

-Tennis

Why would you want CDP? In reality, having CDP advertising on the
host ports is a security issue as it advertises switch information
that should be protected.

True story: I took a Redhat RHCE training class and they were having
problems with the clients not getting dhcp reservations. I fired up
ethereal on my workstation and saw they had not disabled CDP on the
host ports. By looknig at those packets, I saw they had not set
"spanning-tree portfast" which was causing the dhcp problems. Then I
politely told them the version of IOS the switch was very outdated and
vulnerable to a few different attacks. They were a bit chagrined
since it was a linux security class. :}
