sshd doing dns queries on localhost?
Hi,
I noted on my 4.7 machines that when a ssh conection is made, the
following PTR query happens (10.11.1.11 is the src address in the example):
13:23:21.120290 PUBLIC_IP.4523 > PUBLIC_IP.53: 52788+ PTR?
11.1.11.10.in-addr.arpa. (41)
13:23:21.120517 PUBLIC_IP.4524 > PUBLIC_IP.53: 52788+ PTR?
11.1.11.10.in-addr.arpa. (41)
13:23:21.120683 PUBLIC_IP.4525 > PUBLIC_IP.53: 52788+ PTR?

How do fix a good solution against spam..
Heya folks
First of all, sorry if this isn't the correct list, but yet, I think spam is a kind of
network attack and should be treated as a security issue.. I run a working mail server
using Postfix, MySQL, Courier-IMAP, SpamAssassin and ClamAV (amavisd-new) ..
I've checked the configuration file for SpamAssassin, but yet I havn't find any good
solution for spam.. Sure, spam will

rate limiting sshd connections ?
Does anyone know of a way to rate limit ssh connections from an IP address
? We are starting to see more and more brute force attempts to guess
simple passwords "/usr/sbin/inetd -wWl -C 10" is nice for slowing down
attempts to services launched via inetd. Is there an equiv method for
doing this to sshd? Running from inetd has some issues supposedly.
