Interestingly I received the same error with Rsyncd and removing that service allowance also removed the errors. Neither of these services have been setup on this server yet. Is that the possible problem? Is it possible these errors will disappear once these services are installed and started?

Not sure what's wrong with smtp.xml. I'm not at all sure this server needs inbound SMTP so I am going to remove this line from public.xml. Here are the contents of smtp.xml <?xml version="1.0" encoding="utf-8"?> <service> <short>Mail (SMTP)</short> <description>This option allows incoming SMTP mail ...

Sorry. These are SATA drives with EXT4. This shouldn't be limited to an average of 6MBps.

As for the jumbo frames as I mentioned earlier I can reliably get a Windows server to hit 400MBps via this infrastructure without network tweaking. I should at least be seeing 100MBps or more I would think.

I've set up a VSFTPD based FTP server and want to secure the traffic with SSL/TLS. I followed these instructions: https://www.howtoforge.com/how-to-install-vsftpd-server-on-centos-8/#configure-firewall-and-selinux Except I used a 4096 bit modulus instead. VSFTPD starts fine and I cannot find any err...

Oh, that .xml is my problem. Thanks.

Thanks for all the help! Not sure if I should open a new post but FirewallD isn't showing any of the new services I've added to it. When I look at /etc/firewalld/zones/public.xml I see this: <service name="ssh"/> <service name="smtp.xml"/> <service name="ftp.xml"/> <service name="rsyncd.xml"/> <serv...

CentOS Linux release 8.1.1911 (Core) - no GUI installed Previous versions of CentOS used to show the firewall rules that FirewallD was set up to use however my current CentOS8 (first time I've installed 8) does not show anything in IPTables. In fact it shows IPTables is wide open: [root@Server user]...
