Suffice to say that each IP address is automatically blocked for varying lengths of time following any failed attempt. What I am trying to discover is what in particular, if anything, caused this traffic to suddenly start hitting our external server and whether or not we should be concerned about a specific vulnerability. This host is our last remaining Sendmail server. All the rest have been switched to Postfix. None of the other MX hosts are reporting this and so the questions arise: Is this an attack? Is it specifically directed at the Sendmail server or is it just a co-incidence? -- *** E-Mail is NOT a SECURE channel *** James B.

Recently we began seeing lots of these log entries on our off-site mx smtp host. I have googled this but I am not clear from what I have read if this is something we can stop altogether or should even worry about. Comments?

RHSA-2012:1288 libxml2 security update for centos6 skiped?
by ownssh 20 Sep '12

20 Sep '12

I saw libxml2 have a security update on https://rhn.redhat.com/errata/RHSA-2012-1288.html. But centos only update libxml2 for centos 5., it also affect centos6. Centos already update ppid(RHSA-2012:1269), looks like libxml(RHSA-2012:1288) skiped.... Any explanation?

How do boot a xen domu into run level 1
by me＠tdiehl.org 20 Sep '12

20 Sep '12

Hi, I have a C5.8 machine with several DomU's. I fubared the fstab on one of them and I need to get it into single user mode. Does anyone know how to do that? I tried adding single to the extras line in /etc/xen/machine_name but it still tries to start in level 3. To make things worse, the root partition is on LVM. Alternatively, does anyone know how to access the image from DomU? I tried to use kpartx but when I run VGscan, I do not get the lvm activated.

NFS problem

20 Sep '12

We've been seeing what I gather is an old, traditional problem: kernel: lockd: server <ip address> not responding, timed out The things I've found, googling, mostly involve rebooting the NFS server, and I can't do that, it's a home directory server for a *bunch* of people, and this is only one person's workstation. Are there other solutions I haven't found yet? mark
