under another kind of attack
by Olaf Hopp 31 Jul '17

31 Jul '17

Hi folks, "somehow" similar to the thread "under some kind oof attack" started by "MJ": I have dovecot shielded by fail2ban which works fine. But since a few days I see many many IPs per day knocking on my doors with wron password and/or users. But the rate at which they are knocking is very very low. So fail2ban will never catch them. For example one IP: Jul 25 14:03:17 irams1 dovecot: auth-worker(2212): pam(eurodisc,101.231.247.210,<gAulHSNVsNZl5/fS>): unknown user Jul 25 15:16:36 irams1 dovecot: auth-worker(11047): pam(gergei,101.231.247.210,<dPzYIyRVtOpl5/fS>): pam_authenticate() failed: Authentication failure (password mismatch?) Jul 25 16:08:51 irams1 dovecot: auth-worker(3379): pam(icpe,101.231.247.210,<Ws6t3iRVkOhl5/fS>): unknown user Jul 25 16:10:47 irams1 dovecot: auth-worker(4250): pam(endsulei,101.231.247.210,<dceL5SRVGZVl5/fS>): unknown user Note the timestamps. If I look the other way round (tries to one account) I'll get Jul 25 01:30:48 irams1 dovecot: auth-worker(11276): pam(endsulei,60.166.12.117,<slp6mhhViI48pgx1>): unknown user Jul 25 01:31:26 irams1 dovecot: auth-worker(11276): pam(endsulei,222.243.211.200,<s0+6nBhVabHe89PI>): unknown user Jul 25 13:29:22 irams1 dovecot: auth-worker(4745): pam(endsulei,60.2.50.114,<4elhpCJVtcw8AjJy>): unknown user Jul 25 13:30:27 irams1 dovecot: auth-worker(4747): pam(endsulei,222.84.118.83,<kaE1qCJVn7neVHZT>): unknown user Jul 25 16:10:47 irams1 dovecot: auth-worker(4250): pam(endsulei,101.231.247.210,<dceL5SRVGZVl5/fS>): unknown user Jul 25 16:11:45 irams1 dovecot: auth-worker(5933): pam(endsulei,206.214.0.120,<R5H56CRVdJfO1gB4>): unknown user Also note the timestamps! And I see many many distinct IPs per day (a few hundred) trying many many existing and non-existings accounts. As you see in the timestamps in my examples, this can not be handled by fail2ban without affecting regular users with typos. Is anybody observing something similar ? Anybody an idea against this ? Many of these observed IPs are chinese mobile IPs, if this matters. But we have also chinese students and researchers all abroad.

Large Scale Cluster using dsync and tagged director
by Matt Bryant 31 Jul '17

31 Jul '17

Just been reading up on some of dovecot features and was wondering if anyone had played around with large scale systems made up from mutliple small dsync clusters and using tagged director to split users between nodes of a sync'd cluster (rather than nfs). I know traditionally its been shared storage and multiple nodes and dovecots own doco suggest dsync for several thousands rather than millions but given the cloud seems to be all about replication what about many smaller nodes using dsync and scaling horizontally ? The only issue is how does director scale when there are serveral(or rather lots of) 'tags' ... in fact what are the limitations with director ?

I've been running dovecott without trouble for quite a why and now when I added a new user, it is not accepting the user and I can not track the problem.

Hi to all, @Olaf Hopp I've this filter enabled for fail2ban, my question is: could my filters overlap or interfere with those suggested by you? this is my filter: Contents of /etc/fail2ban/jail.conf: [postfix] # Ban for 10 minutes if it fails 6 times within 10 minutes enabled = true port = smtp,ssmtp filter = postfix logpath = /var/log/mail.log maxretry = 6 bantime = 600 findtime = 600 Contents of /etc/fail2ban/filter.d/postfix.conf: # Fail2Ban configuration file # Author: Cyril Jaquier # $Revision$ [Definition] # Option: failregex # Notes.: regex to match the password failures messages in the logfile. The # host must be matched by a group named "host". The tag "<HOST>" can # be used for standard IP/hostname matching and is only an alias for # (?:::f{4,6}:)?(?P<host>[\w\-.^_]+) # Values: TEXT # # Jul 11 02:35:08 mail postfix/smtpd[16299]: lost connection after AUTH from unknown[196.12.178.73] failregex = lost connection after AUTH from unknown\[<HOST>\] # Option: ignoreregex # Notes.: regex to ignore.

(I think I am testing other readers' patience, so if you want to follow-up, you can Email me directly.) > but how often do you have to type your username ? Not often, but I'm not talking the typical case. The larger the population you serve, the more circumstances you'll have to cover. > Only on the initial config of your mailer. After that you are done. Mail reader setups by users is often an error prone process, judging from the number of times I have to correct a setup. This is especially true for an educational institution that typically has a large turnover of accounts. If a user gets it initially wrong, then fixes their mistake, they can't get it to work despite trying all sorts of config variations, not realizing it can't be resolved anymore. Result: trouble call. If someone blows it setting on a multi-user workstation, other users with a working setups can't log in. Result: trouble call. If a student flubs their credentials, all the roommates behind their residential NAT gateway suffer. Result: trouble call. If a user screws up using an external service that slurps their mail (e.g. Gmail, Yahoo, uniboxapp, etc.), or worse, someone malicious does it on puropse, all other users of this service will be DoS'd. Result: trouble call(s). If a user acquires a DHCP address in a polluted network ..., well you get the idea. Not to mention ex-users who forget to remove their mail accounts from their smartphones, leaving a trail of blacklist entries in their wake as they travel from coffee shops to other public WiFi hotspots. > So this is why I decided to use two distinct jails with > different policies. It seems to work reasonable well. Until it doesn't. If it works for you, more power to you. The cost/benefit of a hair-trigger blacklist policy is that it saves you a few log entries showing futile attempts at finding weak passwords (because you have strong passwords, don't you?) at the risk of dealing with any of the above situations.

Just be careful about typos (like twaeking!): users could simply misspell their username, or get mixed up with some another account or alias. This is why I favour targetting known bad accounts, not merely accounts that don't exist. Joseph Tam <jtam.home(a)gmail.com>

Well, I've added the "p" flag and now I will monitor the situation ;-) PS Just as an additional note, just after making this change and reload Dovecot I have detected (oneshot) this error message: Jul 26 22:09:53 server dovecot: imap-login: Error: read(anvil) failed: EOF Jul 26 22:09:53 server dovecot: imap-login: Error: read(anvil) failed: EOF Jul 26 22:09:53 server dovecot: imap-login: Error: read(anvil) failed: EOF Jul 26 22:09:53 server dovecot: auth: Error: read(anvil-auth-penalty) failed: EOF Jul 26 22:09:53 server dovecot: auth: Error: net_connect_unix(anvil-auth-penalty) failed: Permission denied Jul 26 22:09:53 server dovecot: imap-login: Error: read(anvil) failed: EOF Jul 26 22:09:53 server dovecot: imap-login: Error: read(anvil) failed: EOF Jul 26 22:09:53 server dovecot: imap-login: Error: read(anvil) failed: EOF Jul 26 22:09:53 server dovecot: imap-login: Error: read(anvil) failed: EOF But now everything seems to work well (let's hope) ;-) Many thanks Thomas!
