Topic: Can not IP address to blacklist

==== Required information ====
- iRedMail version: 0.8.7
- Store mail accounts in which backend (LDAP/MySQL/PGSQL): MySQL
- Linux/BSD distribution name and version: CentOS 6.5 64bit
- Related log if you're reporting an issue:
- iRedAdmin-pro 1.8.2
====

Dear support,

I add IP address to blacklist, the message is: Records were successfully added.
However when reviewing the Blacklsits I can not find any any record in both All blaclists and IP Address pannel.

I can add domain to blacklists. However, there is no affect, spam still come and smtp connection still be ESTABLISHED.

Spam only stopped when I add the IP to Iptables.

Thanks and best regards,
Minh

Re: Can not IP address to blacklist

Are you running Policyd or Cluebringer for white/blacklist? Any log in Postfix log related to this spam IP?

Re: Can not IP address to blacklist

Dear ZhangHuangbin,

This is the output of netstat -ntlp | grep -i 1003

tcp 0 0 127.0.0.1:10031 0.0.0.0:* LISTEN 30642/perl

Is this mean cbpolicyd is running?

Regards,
Minh.

Yes, Cluebringer is listening on port 10031.

The log you pasted means Cluebringer rejected the client due to your throttling setting.

Re: Can not IP address to blacklist

Yes, I enable throttling. I also want to add this IP to blacklist. Do you have any idea to check how we can fix this issue in Iredadmin Pro?

If you add IP as blacklist with iRedAdmin-Pro, this IP should be rejected by Cluebringer. Not sure why it doesn't work in your case.
Is it possible to let me login to your server to debug iRedAdmin-Pro and Cluebringer? So that i can make sure both of them are working as expected.

Re: Can not IP address to blacklist

Thank ZhangHuangbin,

Last night I decided to restart whole server. After that, I can add IP to blacklist and it's OK now. I think that I had problem with mysql. However, it seems that I have another problem: Mail sending and receiving is very slow from both pop3 account and roundcube webmail. I often receive the messages like: session timeout, internal server error/incorrec configuration, service not available (error code 500),... Maybe do I open new thread to have you help on this?

For IP Blacklist, now I can make this thread SOLVED.

Many thanks and best regards,
Minh

Re: Can not IP address to blacklist

Dear ZhangHuangbin,

Sorry for requesting reopening this thread. Here is my situation:
In Add whitelist and blacklist, I add, for example, 3 IPs to Blacklist:
112.109.90.17
84.253.63.155
84.83.63.155
I got "records sucessfully updated"
However when coming to All blacklist pannel, I only see:
112.109.90.17
84.83.63.155
So it's lack of 84.253.63.155
Could you please help me find out why because 2 days ago I added and saw 84.253.63.155 in all blacklist pannel (After that I deleted this IP to check fail2ban if it can ban this IP automatically).

If you still want to access my server to check, please let me know they way you want to use to access my server.

Is it possible to let me login to your server to debug iRedAdmin-Pro and Cluebringer? So that i can make sure both of them are working as expected.

Thank and best regards,
Minh

If it worked last time you added this IP, then it should work as expected. Could you please try again? make sure no space between digit numbers and dots.

Re: Can not IP address to blacklist

Dear Zhang,

I tried a lot of time. It's very weird. I can add 84.249.63.155 successfully but when adding 84.250.63.155, 84.251.63.155, 84.252.63.155, 84.253.63.155, 84.254.63.155, system message is successully but those IPs do not show up in IP blacklist pannel.

Minh.

2. Backup file iredutils.py

Re: Can not IP address to blacklist

Try below steps:

1: Create file 'xxx.patch' with provided content, save it in any directory. e.g. /root/xxx.patch.
2: Backup file /var/www/iRedAdmin-Pro-MySQL-1.8.2/libs/iredutils.py.
3: Open terminal, and verify this patch with command 'patch --dry-run':

# cd /var/www/iRedAdmin-Pro-MySQL-1.8.2/
# patch --dry-run -p1 < /root/xxx.patch
patching file libs/iredutils.py

4: if you see output like above and no error/warning message, it's safe to patch it immediately (without '--dry-run'):

# patch -p1 < /root/xxx.patch

5: Restart Apache service to load patched code.

Dear Zhang,

My output when running --dry-run is:

[root@mx1 iRedAdmin-Pro-MySQL-1.8.2]# patch --dry-run -p1 < /root/iredutils.patch
patching file libs/iredutils.py
Hunk #1 succeeded at 48 with fuzz 1.

Is it OK? I googled to find the meaning of Hunk #1 succeeded at 48 with fuzz 1 but can not find what does it mean by "at 48 with buzz 1"
