fail2ban problems - not banning
by Gary Stainburn 06 Jan '21

06 Jan '21

Hi everyone, I've got fail2ban and firewalld set up on a C7 box, in theory protecting dovecot, exim and ssh but I'm not convinced it's doing anything. in /var/log/fail2ban.log I'm getting loads of entries such as: 2020-12-22 19:08:08,100 fail2ban.actions [1836]: WARNING [dovecot] 78.128.113.67 already banned I think this is because the actual ban is not working. I have entries such as: 2020-12-22 19:38:27,619 fail2ban.utils [1836]: ERROR 7f119e95f7f0 -- exec: ports="0:65535"; for p in $(echo $ports | tr ", " " "); do firewall-cmd --add-rich-rule="rule family='ipv4' source address='113.110.47.81' port port='$p' protocol='tcp' reject type='icmp-port-unreachable'"; done 2020-12-22 19:38:27,619 fail2ban.utils [1836]: ERROR 7f119e95f7f0 -- stderr: 'Error: INVALID_PORT: 0:65535' 2020-12-22 19:38:27,619 fail2ban.utils [1836]: ERROR 7f119e95f7f0 -- returned 102 2020-12-22 19:38:27,620 fail2ban.actions [1836]: ERROR Failed to execute ban jail 'dovecot' action 'firewallcmd-rich-rules' info 'ActionInfo({'ip': '113.110.47.81', 'fid': <function <lambda> at 0x7f119f084050>, 'family': 'inet4', 'raw-ticket': <function <lambda> at 0x7f119f0845f0>})': Error banning 113.110.47.81 I've done some Googling and received lots of responses about fail2ban failures but I can't find anything relating to this. Anyone got any ideas?

dovecot option PROFILE=SYSTEM
by david 06 Jan '21

06 Jan '21

Folks In examining the file /etc/dovecot/conf.d/10-ssl.conf I see the text line: ssl_cipher_list = PROFILE=SYSTEM Yet, I cannot find any documentation that explains what that causes, where the values are stored. I ask because I don't see that text line in other installations of Dovecot 2.3 on other distros. Can anyone point me to an explanation? David

PostgreSQL 13 on CentOS 7
by H 06 Jan '21

06 Jan '21

I am compiling an application that uses postgreSQL 13 and Qt 5.12. I have built the latter from scratch and successfully linked with libraries for postgreSQL 9.6 (the current version on CentOS 7) but have run into problems with postgreSQL 13. The server, client and libs are available in the postgres repository but I also need the devel library which in turns requires llvm5.0-devel which does not want seem to available... Has anyone successfully build an application use pg 13 or otherwise used postgresql13-devel? Thanks.

Is EPEL compatible with Stream?
by Kay Schenk 04 Jan '21

04 Jan '21

Hello all-- All good in the Stream for me. :) Because Stream will tend to be more "forward moving" than previous CentOS releases, is it still OK to set up EPEL as a repo? So far, I've only installed terminus fonts from CentOS 8 EPEL, but I'm just wondering about this. Generally, are there any cautions against enabling specific repos to use with Stream? -- ------------------------------------- "Don't let anyone dull your sparkle." MzK
