Hi! I have a minimal installation of centos8 + packages for freeipa as a vbox vm. there is something strange with the firewall rules : [root at ldap ~]# iptables -S -P INPUT ACCEPT -P FORWARD ACCEPT -P OUTPUT ACCEPT [root at ldap ~]# firewall-cmd --get-active-zones public interfaces: enp0s17 [root at ldap ~]# firewall-cmd --state running [root at ldap ~]# firewall-cmd --zone=public

So, I'm seeing a bunch of DHCPv6 traffic coming from my CentOS7 machines. Basically, the machines are trying to send router solicitations, the packets are blocked at their egress firewalls, and I get to see the logs. I don't wish to disable IPv6. I don't wish to statically configure IPv6 at this time. I wish to have the machines no longer attempting to send router solicitations as

Is there an DHCPv6 client in CentOS that supports prefix delegation correctly? The old version of dhclient can't set a requested prefix delegation length, so isn't very useful, and I can't get the even-older wide-dhcpv6 from EPEL to work. -- Chris Adams <linux at cmadams.net>

Hello! As discussed in the previous thread about "Dovecot deliver logging problem and procmail" I have made a small patch for procmail to deliver through dovecot's deliver program (or any other delivery program). So Procmail does not write the mailboxes directly any more. So delivery is done through pipes and an external program which can deliver the files. Since dovecot's

Ady, There are at least 3 ways to set up your DHCP server to differentiate between std DHCP, BIOS PXE and UEFI PXE. Option 93 (arch) is one way. In ISC syntax, here's 3 ways: 1. Match on VCI class "pxe-clients" { match if substring (option vendor-class-identifier, 0, 9) = "PXEClient"; set vendor-string = substring ( option vendor-class-identifier, 0, 9);

Hello; I've run into a rather interesting problem on CentOS 7. According to sysconfig.txt (part of the initscripts documentation), I can set the following variables in ifcfg-ethX: DHCPV6C="yes" DHCPV6C_OPTIONS="-S" I've done so, but nothing is populated to /etc/resolv.conf and so DNS does not work.
