[CentOS-docs] How to back up a running KVM guest
Hi Please create a page on the wiki for a HowTo with the subject: How to back up a running KVM guest This will explain how to use LVM to take a snaphot of a KVM guest's virtual hard drive and rsync it to a remote backup server. I have a prototype running but there are still many issues to be resolved affecting performance, security, reliability, automation. I intend to include a to-do list so that others can contribute. The to-do list is quite long so it's unsuitable for a single forum or mailing list post, where discussion about various points on a single thread could get confusing. Maybe individual issues could be posted in the forum for discussion. Are wiki pages created in a hidden state and made visible when they reach the required quality? Please also grant permission for me to alter the KVM HowTo: http://wiki.centos.org/HowTos/KVM ...so I can add the salient points from this forum post... http://www.centos.org/modules/newbb/viewtopic.php?topic_id=19034forum=38 Thanks, Julian Price ___ CentOS-docs mailing list CentOS-docs@centos.org http://lists.centos.org/mailman/listinfo/centos-docs

[CentOS] fetchmail SSL protoco; issue
I am using fetchmail to collect mail from some secondary mail accounts, among which is hotmail. So far I have used hotwayd to fetch the mail from hotmail using httpmail. Hotmail now supports pop3 access, so I decided to change fetchnail to fetch the mail directly over pop3. This works, but whatever I try, I get an error message when I run fetchmail: Invalid SSL protocol 'SSLv23' specified, using default (SSLv23). Invalid SSL protocol '' specified, using default (SSLv23). The relevant part of my .fetchmailrc is included below (userids and password changed for privacy reasons :-) poll pop3.live.com port 995 proto pop3 user xx...@hotmail.com password yy no keep ssl sslproto ssl23 fetchall to myuserid The error message remains almost the same when I remove the sslproto option, only the second line is printed My mail is correctly fetched however.

[CentOS] How to add ClamAV to Postfix?
I sent this email to the Rehdat list, but I thought the Centos users might be more inclined to have the command-line solution I am looking for, so I thought I would post it here too: I would like to add anti-virus to my email server. Currently I have Postfix, Dovecot, PHP, and Squirrelmail installed. The users only use Squirrelmail to access mail. I am looking for command-line instructions, since I have limited access to the server itself (I am using SSH). ClamAV seems to be most common linux AV package, so I assume I should be using that. I'm not sure if I should be using Amavisd or MailScanner, or neither. I believe I need one of them to act as the glue that connects Postfix to ClamAV. Apparently none of these packages (Amavisd/MailScanner/ClamAV) are part of RHEL5, so I have to get the RPMS from somewhere else.

MailScanner is available from http://www.mailscanner.info Hi Craig, In one of my failed attempts before I posted, I had gotten those RPMs from rpmforge, perhaps I was on the right track. I was following these instructions: http://www.linuxmail.info/how-to-install-clam-antivirus-centos-5 I will install install ClamAV from those RPM's, make a backup using CloneZilla, then I will only have to get either MailScanner or Amavis to work. thanks! looks ok - MailScanner and Amavisd have their own documentation and I would recommend that you install yum-priorities package when using 3rd party repos like rpmforge with CentOS MailScanner handles the clamav virus definition updates for you...don't know about amavisd-new Craig ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

But certainly no way near 60% unless you are referring to one of those new Atoms/Nano platform. Even then, they usually come with PSU optimized for low power operation. It would be interesting to put a wattmeter inline on the power cord to see how much current it's drawing running vs. in sleep state. I guess with an AT machine, one would have to use one of those old timers that switch on a plug something else that uses a bit of electricity, but I bet less than a power supply in sleep mode. Including conversion inefficiency, my gaming PC sucks some 180W on idle, I just sent it into standby and my wattmeter says 4W. It isn't spec'd to be accurate at less than 10W so the actual draw could range from 2W to 8W. Certainly nothing too significant, the total environmental cost including materials and energy is likely less than a new timer :) ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Make sure you are not using Seagate 7200.11 series hard disks for this unless you've somehow obtained and updated the firmwire. Frequent power cycles increases the chances that you will hit their firmware bug that apparently bricks the drive if the drive internal log is at some specific entry number before the power cycle.

MailScanner is available from http://www.mailscanner.info I've always liked MimeDefang best because of it's well-designed multiplexer that permits quick operations to continue without making an extra process wait for the slow jobs. It was designed to work with sendmail and the rpmforge package works along with clamav requiring at most a change in group ownership on clamd's socket. However, I thought someone said that postfix's milter emulation is now complete enough to work with MimeDefang too. -- Les Mikesell lesmikes...@gmail.com ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

The redirect is okay, the invalid security certficate isn't, but will be fixed (someone just needs to install the new certificate). I don't think it did that yesterday. The redirect has been there for a longer time, the SSL certificate has run out, the new one hasn't been installed yet. Sorry for the inconvenience.
