Hi, after a long general power failure, I had to power off/on my soon to be 6.4 firewall (updated to 6.4, but not rebooted yet). After the off/on, everything seemed to be fine.

Greetings, Per the subject line, how does pop3 get tcp-wrapped when using dovecot?

I upgraded a development server last week, and it started spewing selinux errors to the log. I googled. What finally *seems* to have stopped it was a) setsebool -P httpd_setrlimit 1 b) yum downgrade selinux-policy\* This is on a 6.3 box. Has anyone else seen this behaviour? mark

Hi, I am trying to get ipv6 firewall running. I did a very simple ip6tables rules and noticed very long running yum updates. I think that happened because firewall is dropping outgoing packets to port 80. Well, I thought to mitigate the issue and changed outgoing from drop to reject. Now I try manually # strace telnet 2a02:180:ffff:1::551f:b966 80 ... connect(3, {sa_family=AF_INET6,

I have a CentOS 5.8 box that is dropping packets (just from ping). The network is 8139 RTL-8139/8139C/8139C+ Rev 10 Adding the parameters "pci=noacpi acpi=off " has helped but it still happens. Is there something else that helps the network not drop packets? Thanks, jerry
