According to <http://wiki.centos.org/Manuals/ReleaseNotes/CentOSLiveCD5.5> "There is a "Network Install" option on the Live CD that is the same as our CentOS-5.5-i386-netinstall ISO". I've looked quite carefully at my CentOS-5.5 Live CD (on a USB stick), and I don't see a Network Install option anywhere. Could some kind soul explain where it can be found,

I have a working CentOS-7 machine. I want to install grub2 on a USB stick (without altering my present system in any way) so that I can boot the present system from the USB stick. Could some kind (and expert) soul explain precisely what to do. If it were possible to boot other systems on the computer as well that would be an added bonus. I did google for this, but all the sites I saw wanted to

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 running CentOS-7 on my home server, and have setup postfix + dovecot + spamassassin. Everything seems to be working fine, except that while spam is being marked as ***Spam***, it is ending up in ~/Maildir/cur/ . I'd like to divert it to ~/Maildir/.Spam/ (where I can examine it with sa-learn). What is the simplest way to do this? -- Timothy Murphy gayleard /at/ eircom.net School

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

I'm running postfix + dovecot on my CentOS-7 home server. When I send myself a message I get this error message in /var/log/maillog: Aug 9 12:59:57 alfred postfix/lmtp[31336]: B0D02220748: to=<tim at localhost.gayleard.eu>, orig_to=<tim at localhost>, relay=alfred.gayleard.eu[private/dovecot-lmtp], delay=475, delays=474/0.03/0.02/0.09, dsn=4.3.0, status=deferred

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>.

I suppose a lot of it depends on your needs. For us, we run internal DNS servers for all the VMs we have running; mostly for software development and monitoring. It makes sense for us to do so as we have mostly Macs (and my Linux workstation) that work better using DNS. Had we been a mostly Windows shop, we'd likely use NetBIOS internally with some Dynamic DNS for win clients. We also have

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

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]:

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 .

I have a 1.5TB Western Digital hard disk (WD15EADS-00R6B0) on my CentOS-5.7 server, which has become incredibly slow for some operations, eg rsync, BackupPC archive, e2fsck, although it seems to work fine for ordinary file operations, and "smartctl -a /dev/sdb" does not report any errors. For example, running "e2fsck -p /dev/sdb5" on a 250GB partition on this disk took over 24

If I boot into CentOS on my home server from a Live CD or USB stick and go to Troubleshoot, it lists OS's it finds on the machine. How does it find these OS's? Presumably it looks through all the partitions on all the hard disks for something that looks like an OS? But how exactly does it identify an OS? -- Timothy Murphy gayleard /at/ eircom.net School of Mathematics, Trinity College,

I have a strange problem on a CentOS-5.8 machine. I can only login as root. If I try to login with one of the user's names, it hangs for a long time. I thought it hung forever, but I just found that I do login after "su tim" after 5 minutes.
