denyhosts configuration
Hello,
I've installed denyhosts on centos 5.3 trying to block automated
attacks on ssh. It appears to be working in that entries are being added to
/etc/hosts.deny yet the daily emails sent from denyhosts show only one ip
being added perday when the total is many more than that. My config is
below, i've gone over it and am not seeing what i missed. Suggestions
welcome.

Centos-specific Denyhosts Howto Anyone?
Hi, after reading the docs (no man page) and seeing a few example
howtos, I see none for Centos specifically.
I hereby offer to write this and even host it, and any other wiki-able
howto you want, if you can school me on the first few steps relevant to
how to link up the current rpmforge rpm for RHEL4-64. See, right now,
the one for centos loads into the /usr/share/doc, which is an odd place

Hi there,
I know this is the classic RTFM list question but... I've really tried

AllowHosts / DenyHosts
I'd like to see a feature of the commercial ssh in openssh:
AllowHosts xxx.yyy.xxx.yyy *.domain.net
DenyHosts xxx.yyy.xxx.* name.domain.net
This allows or denies connects from certain machines (including wildcard
matching).
Is there any chance for this feature to be included? No, we don't want to
use tcp-wrapper for this.
Bye.

lua policy for Weakforce and web mail failed login attempts
The good news is I believe I got Weakforce running

COMPATIBILITY: AllowHosts/DenyHosts/SilentDeny not supported
Hi,
here's another feature request that I just found and where I would like
to hear your comments first:

dovecot under attack
Hi,
I?ve posted this before but no one was able to help. I can?t figure out
what they are trying to do, and if I should be concerned.
I am running dovecot version 0.99.14 on Fedora Core 4. It appears that my
dovecot server is under attack. This morning in my system e-mail I saw
this:

denyhosts-like app for MySQLd?
Hi all,
?Is there any app like denyhosts[1] but intended for MySQLd service?
We have a mysql ports (3306) opened for remote connections, and
obviously the /var/db/mysql/machine_name.log is full of these kind of
entries:

ldap host attribute is ignored

i have set logging in sssd to 9:
cache_credentials = true
debug_level = 9
I first tried a user with the correct host attribute, then a user
without the host attribute. The output in the logfiles are the same.
Note: USER ist not a local user. Without correct ldap password

How to bypass checking of system users by virtual users?
Hi, I have one real domain (abusar.org) and the others are
virtual. So I configured dovecot.conf as the following:
# for abusar.org, real domain
mail_location = mbox:~/.mail/:INBOX=/var/mail/%n
# for the remaining virtual domains
userdb static {
args = uid=17 gid=17 home=/var/spool/virtual/%d/.home/%n mail=mbox:/var/spool/virtual/%d/home/%n:INBOX=/var/spool/virtual/%d/%n
}

What are they trying to do here?
Hi!
I?m new to the list, and I?m not really having a ?problem?, but I?m seeing
something in my log files that I wonder if I should be concerned.
I?ve been using Dovecot (dovecot-0.99.14-8.fc4) on my Fedora Core 4 (kernel
2.6.17-1.2142_FC4) machine from quite some time.
For the last few days, I?ve been seeing this in my daily ?Logwatch? e-mail:

upgrade to 3.0.22, problem authenticating to AD
We upgraded our Centos 4.3 box's samba from 3.0.10 to 3.0.22 using sernet.de rpms. Prior to upgrading, we had this box authenticating to AD just fine, but now it is broken. Here is part of my log file that might show what is going on.

auth trouble
Debian Lenny, Dovecot v 1.0.15.
I'm getting a lot of what I think is a local socket asking
dovecot:auth to verify username/passwords:

Note the empty 'rhost='. That's why I think it's on the
server. I see others that look like bots:

Pam authentication failure message but it works
I am running Centos 6.4 64bit.
Dovecot 2.0.9
I am getting the following messages in /var/log/secure, which looks like
the pam authentication is not working but the users are allowed to login
and the system works great.
I am wondering if pam is actually failing and yet the system is getting
the login info from elsewhere, or is this just a nuisance message?
