a couple containers lost networking a couple days ago, i'm thinking it likely the issue is iptables commands being issued by system code somewhere. we manage iptables with our own firewall script. we're running openvz7 on centos7. i already removed firewalld, and i would like to know what code causes the following three entries in /var/log/messages:



Oct 5 15:53:05 pecan kernel: Bridge firewalling registered

Oct 5 15:53:16 pecan systemd: Started SYSV: setup firewall (iptables) rules (INPUT chain for the HN, FORWARD chain for clients).

Oct 5 15:53:48 pecan prl_disp_service: 10-05 15:53:48.987 W /cmn_utils:2214:2391/ Start setting basic firewall rules...





iptables firewall openvz

          Postfix configuration issue with fips on centos 7; mailgun relay

          Image
          Clash Royale CLAN TAG #URR8PPP up vote 0 down vote favorite I am trying to setup postfix to relay all mail generated on the local machine via SMTP to a mailgun relay. I have used the mailgun relay before with success on an ubuntu server, but I am migrating to a Centos 7 server which I will be running in FIPS mode. There error log is below, slightly sanitized. I have a small enough network that I choose to have each machine reach out to mailgun individually (this the loopback-only, 127.0.0.0/8 restrictions) and no firewall open port allowing smtp in to the machine. I assume the FIPS mode (and with it disabling of MD5) is causing problems, but I don't know how to overcome it or if it is even possible for tls_fprint to use some supported hash such as sha256 or sha512. However, the relay=none is slightly concerning since I have relayhost set, but perhaps that is because the smtp process is failing? Any help would be appreciated! postconf -n: alias_database = hash:/etc/alia
