similar to: Ddclient: is this a problem?

when I ran "sudo yum update" on my CentOS-7.2.1511 today, ddclient was updated to ddclient-3.8.3-1.el7.noarch (from 3.7.3), and ddclient.conf was moved to ddclient.conf.rpmsave . When I move it back, "sudo systemctl restart ddclient" fails with the error (in "sudo journalctl -xe | grep ddclient") Apr 21 13:05:39 alfred.gayleard.eu.localdomain touch[8590]:

I find ddclient stops running after a time on a remote CentOS-6.4 server. Has anyone else found this? I think it has been happening for a couple of months. I notice because I get complaining messages in my logwatch. -- Timothy Murphy e-mail: gayleard /at/ eircom.net School of Mathematics, Trinity College, Dublin 2, Ireland

Is anyone running ddclient under the CentOS-7? It doesn't seem to be in epel. I've downloaded the source and it is running, but giving me endless warnings. Could I run it as a daemon? I'm not sure if this is allowed nowadays. -- Timothy Murphy e-mail: gayleard /at/ eircom.net School of Mathematics, Trinity College, Dublin 2, Ireland

I use dyndns's (free) service to access a remote machine with a dynamic IP address. The machine is running under CentOS-6.0. I can ssh into the address given me by dyndns (*.homelinux.com), but when I do this I get the warning "reverse mapping checking getaddrinfo for" * "failed - POSSIBLE BREAK-IN ATTEMPT!" This doesn't really matter, as I normally use OpenVPN for

I'm running two servers, one with a fixed IP address and the other with a dynamic address. This is probably a very ignorant question, but what does dyndns do that I could not do myself? -- Timothy Murphy e-mail: gayleard /at/ eircom.net School of Mathematics, Trinity College, Dublin 2, Ireland

I have a CentOS-6.2 server in Italy. Every few months the server gets into a strange state and stops working after a power outage. I should say that this does not occur after every power outage; I suspect, but have no real evidence for this, that if the power comes back too quickly then the machine gets confused because it is in the middle of closing down. If I am in Italy the solution is simple;

This, IMHO, is one of the more annoying bugs with the newer GRUB (which i assume is the bootloader you are using). Specifically the newer grub can't, won't boot from a drive other than the one grub is on. suggest you revert to grub 0.97 or, if any boot loader is or can be put on the drive with the 6.5 distro you can make that drive the boot drive in the bios, which is how i do it. i.e.

I'm trying to install spamassassin on a postfix/dovecot server, running CentOS-6.4, following the instructions at <http://wiki.centos.org/HowTos/Amavisd>.

Probably. The fact remains that booting was attractive, and now it isn't. --

Is there any point in running NetworkManager on a server? The IP addresses of the two server NICS are fixed (192.168.1.2 and 192.168.2.2 .) I'm not clear if it is necessary in some way to run NM on a CentOS system? -- Timothy Murphy e-mail: gayleard /at/ eircom.net tel: +353-86-2336090, +353-1-2842366 s-mail: School of Mathematics, Trinity College, Dublin 2, Ireland

Is there such a thing as a CentOS rescue disk? Google gives many links to such a thing, but when I pursue them I do not get to an URL where I can actually download one. -- Timothy Murphy e-mail: gayleard /at/ eircom.net School of Mathematics, Trinity College, Dublin 2, Ireland

Has the CentOS logo disappeared from CentOS-7? I thought the logo in CentOS-6 was very pleasant. Also I liked the way in which one increasing circle inside another showed how the boot was progressing. The dots going round and round in Microsoft fashion in CentOS-7 is a retrograde step, I think. One always has the fear it might continue forever. -- Timothy Murphy gayleard /at/ eircom.net School

I'm getting the (unintelligible to me) error message ipmi_si: Could not set up I/O space ERST: Failed to get Error Log Address Range when I try to boot any OS on the grub menu apart from the one I last installed. (Actually, Windows also boots properly.) I wonder if anyone has had this error message, and worked out where it comes from? I googled for it, and it has come up many times; but

Has anyone succeeded in installing CentOS-6.0 by PXEboot. If so, would you say how you did it, please. I tried (on an HP MicroServer), but gave up in the end and used a USB stick installation instead. But I'd be very interested to know how to do it, for the future. Unfortunately I didn't keep a proper note of my PXEboot attempt, but IIRC the problem was that install.img was not found,

My HP MicroServer crashes with a kernel panic when booted into kernel-3.10.0-327.3.1.el7.x86_64, but runs perfectly under kernel-3.10.0-229.20.1.el7.x86_64 .
