as previously mentioned, it's sshd: not ssh:
ssh will do reverse dns lookup when:
/etc/hosts.allow
sshd : paranoid
- or -
/etc/hosts.deny
sshd : paranoid
all : paranoid
"paranoid"
will for the reverse lookup
- you can use the allow/deny with "except" and
do the double negative too
Would there be anything I could do in the way of setting public keys
that would bypass the lookup? Also, since I don't see the "possible
breakin attempt" in my logs anymore, I'm worried that there might be
some kind of automatic blacklist somewhere -- is that true?
