What is BBN IAD?

[frank....@belgacom.be]

Dear audiency,

I ran a scan on some of my systems, and found some of following ports
listening

iad1 1030/tcp BBN IAD
iad1 1030/udp BBN IAD
iad2 1031/tcp BBN IAD
iad2 1031/udp BBN IAD
iad3 1032/tcp BBN IAD
iad3 1032/udp BBN IAD

I checked rfc 1700, but can't find more info on iad or BBN

Question: Does anybody know what this is supposed to be? I doesn't run from
inetd, so where do I start looking?

Answer: ask the sysadmin

Reply: that is a loopback interface ;-)

Regards,

Frank Lenaers

I think you mean you found these in the /etc/services
file, right? I seriously doubt you're seing traffic
on these ports. The presence of these in this file is to document
the services, and to support 'getservbyname()' -- it doesn't mean
your system is supporting these services.

This is the BBN (Bolt, Beranek and Newman) Interface Access Device,
which operates as a bridge/router between IP, X.25, asynch links, etc.

Do you have Site Patrol for a firewall??

Ummm... are there FTP jobs running? These are in the anonymous port range
for bezerkely-style systems. FTP (and any other app that binds a random
port) will bind ports starting at 1024 and increasing.
