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: dovecot: Authentication Failures: rhost= : 23431 Time(s)

I noticed that my server has a lot ca. 1000x auth failure from different alocated in China / Romania and Netherlands per day since 3 days It looks to me like somebody was trying to get into server by guessing my password by brute force. what would be the best to stop this attack and how? the server running apache mysql and ftp PORT STATE SERVICE 21/tcp open ftp 80/tcp open http 443/tcp

I am having issues integrating a FC3 system with AD running on W2k3. I can not figure out why the user ID mappings and Group ID mappings are going stale.

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: dovecot: Authentication Failures:

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 } passdb

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.

Hai.   Config. Debian Stretch, samba 4.7.7. member server AD backend.

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: > May 31 09:00:54 server dovecot-auth: pam_unix(dovecot:auth): authentication failure; logname= uid=0 euid=0 tty=dovecot ruser=admin rhost= Note the empty 'rhost='. That's why I think it's on the server. I see others that look like bots:
