Re: Cisco says attacks are due to operational practices

After a quick (<30 sec) trip to the man page, voila!
To use non-privileged ports, add to /etc/config or ~/.ssh/config:
This disables attempting rhosts-style authentication, which any sane server
should reject anyways. Why these are still enabled by default escapes me.

Its not a bug, its a leftover from rsh days - if the connection originates
from a port below 1024, you could assume *cough* that the credentials the
connection supplies are authentic, since the process needs to be root to
bind to ports < 1024.
This isn't a "but thats flawed!" discussion seed, take that to bugtraq.
There's a flag to ssh somewhere to stop it doing that. Yup, -P .
