They include only the new hypervisor rpms, you still use the stock centos dom0 kernel. Are there centos/redhat kernels rebuilt with newer Xen or do you have to do this yourself? No need to re-build the kernel. I see source for kernel 2.6.18 with Xen 3.4 here: http://www.xen.org/products/xen_source.html but that kernel does not have all the fixes that have gone into the RH/Centos 2.6.18 kernel.

Fajar Priyanto wrote: Hi all, Is it possible to send mail from CLI (bash, python) without any LOCAL SMTP installed, using SMTP on another machine. Care to give a glimpse of the code? Thank you. Personally, I'd use the default Centos install of sendmail because it's there, it's easy, and it works the way mail has been intended to work for decades. The default setup is to accept only from localhost, but send anywhere. If you want to relay through a known host, configure SMART_HOST in /etc/mail/sendmail.mc and restart the sendmail service. Then your scripts and other programs can simply run sendmail to queue/delivey instead of doing it themselves, and can deliver to local recipients as well as remote. If you really don't want a mailer and are ok with failures or want to handle queuing and retries yourself, the epel repo has perl-Mail-Sender which is a fairly complete smtp send-only client.

Re: [CentOS] adding users on multiple servers
If you have your own account on each of the boxes the ssh key method is the best. 1) Create ssh keys for YOUR unprivileged user account. 2) Add YOUR account to /etc/sudoers by adding: userALL=NOPASSWD: /bin/su - Then from there you can use clusterssh to connect to all the boxes simultaneously. Issue the 'sudo su -' command while logged in with your account, then run add the new users on all of the systems. Just another idea.

Thanks Craig,
Do you have multiple secondary LDAPs using slurpd?
Its is pushing or pulling?
I may just use that.

Hi,
From what I gather, OpenLDAP on Centos 5.x pulls LDAP changes from
central LDAP server to a secondary LDAP server.
So in other words, you can have your second LDAP server pull the db
based on either;
type=refreshOnly
which mean the pull interval will happen when ever you specify or;
type=refreshAndPersist
which mean after a pull, keep the pipe open for any changes made.
Now in Ubuntu one can have there primary LDAP push the changes to
all
the secondaries.
Can I somehow enable push in Centos OpenLDAP because pull seems
pretty
lame in this case.
I tried but to no avail.
Hope the answer isn't Son, thats just the way it iz.
my reading of syncrepl matches your understanding but I'm still
using
slurpd so what do I know.
You should know that the philosophy of OpenLDAP software
developers is
that if you actually want to run an OpenLDAP server using newer edge
features (and syncrepl is surely one of them), then you should be
building the latest from source and not relying on distribution
packages
which exist mostly for providing ldap libraries for other software.
There was a recent discussion about this very topic because
Debian/Ubuntu is using a 2.4 version that is also out of date and
very
buggy where syncrepl is concerned. Obviously CentOS is using 2.3.43
which is considered out of date by OpenLDAP software developers.

MHR wrote: but I just don't like to do it. 30 systems? Yoik! Out of ~300 .. As for moving from 4 to 5, that's not a trivial thing at all - and it's not an upgrade per se unless you have LOTS of faith in the process. I always reinstall across releases, and that's a royal pain (though usually worth it for the new features, like a newer GNOME and all that goes with it). Funny thing is for me the hardest part is getting the downtime to do the work, the OS reinstall is easy, the apps already support it and cfengine automatically configures the systems with everything they need. I can re-install a system and get the apps re-installed in ~30 minutes, but it's a real headache for the apps guys to take the apps down and/or move customers off those systems to other systems. And I'm not in *that* big of a hurry I have other things I am working on of course.. I came across a system a few days ago that had an uptime of over 1000 days...here it is [r...@us-mon001 ~]# uptime 19:22:02 up 1012 days, 4:24, 1 user, load average: 0.04, 0.20, 0.26 [r...@us-mon001 ~]# cat /etc/redhat-release Red Hat Enterprise Linux AS release 4 (Nahant Update 1) Part of me doesn't want to re-install it..(I have no immediate plans to..) You know your missing a kernel update or two when your uptime gets over 3 years. BTW, certain specific upgrades would be really nice. For one thing, Google's Chrome browser is now available for Linux, but you have to have a newer version of (I think it was) gtk that's not available on RH/C 5 at all - yet. Chrome..google. While I'm sure it's a nice browser I don't trust google with my information.. Ah, well, patience in this particular arena pays off - we get the best support and solid reliability for free, so a little wait, or even a long one, is worth it in my book.
