ip aliasing on bonded interface possible?
Has anyone successfully created a bonded interface (bond0) with say
two nics AND also then aliased that interface to get bond0 and bond0:1
(for an alias ip)
I just want to know if it's possible and reliable
Thanks

Likelihood of deviation
Hi,
I have a dataset of 78.903 news articles pertaining to 340 corporate
takeovers.
Mean 231.3871 [articles per takeover]
Std. Dev. 673.6395
I would like to calculate the probability of a certain number of news
articles if I had more takeovers available.
How likely is it to have X articles if I had Y takeovers?
How can I do that?
Thank you very much,
Michael

failover with conntrackd
Hi.
Is anyone using conntrack-tools to implement gateway failover on a
network with windows clients?
I set it up with ucarp and keepalived, and found that gratuitous ARP
doesn''t always seem to update the cache on Windows machines. It works
the first time, but if a second failover happens, the client continues
to send stuff to the wrong MAC address. Linux machines work fine.

Missing yum-priorities in 5.4?
I am looking for yum-priorities or any info on any changes here for
CentOS 5.4. There is also a forum post for this here:
<https://www.centos.org/modules/newbb/viewtopic.php?topic_id=22798&forum=37>
Is this missing on purpose? Function merged with another yum package?
Or is it just missing as an oversight?

Managing updates to non-centos packages
Hi,
I'm looking for some documentation (or advice) on how to best manage
a -mostly- upstream binary compatible CentOS installation.
I enabled the rpmforge repository in order to install a few packages
not available in base/updates/centosplus. But, now when I do a "yum
check-update" yum wants to update a whole stack of packages because
it's found newer versions at

OT: HOWTO: Create a 90mbit bonded link 600 metre s away with Cat 3 or telco wire [long]
I was given the challenge recently of creating a LAN-LAN bridge between two

having to resort
to an expensive and finicky 5 Ghz wireless link. I was able to create a 90

ctdb tcp kill: remaining connections
Hello,
we are using ctdb 4.15.5 on RHEL8 (Kernel 4.18.0-372.32.1.el8_6.x86_64) to provide NFS v3 (via tcp) to RHEL7/8 clients. Whenever an ip takeover happens most clients report something like this:

Any one have a good example...
...of a shell script for rsync that won't start again if it is already running?
I thought of using a lock file, but what if it is killed mid script or bombs?

OT: CentOS hosting recommendations
Hi everyone,
I am looking for a dedicated server with CentOS. Any recommendations?
Ideally I would like to use one of the CentOS sponsors, but I think
that there are far too many to be able to compare them all by
refreshing (maybe there is a page with just a list of links to sponsors
but I couldn't find it).
Thanks

heartbeat, drbd init scripts and chkconfig
Hi,
We are using the heartbeat and drbd packages from latest centos (4.3)
extras repository.
Upon installation of both packages I noticed that if you "chkconfig
heartbeat off" that will cause drbd to chkconfig'ed on. And visa versa.
After doing some trouble shooting it turns out the "BEGIN INIT INFO"
sections appear to be the cause.
drbd has:

TFP inside firewall
Hi,
I have a setup where the tftp server is inside the firewall.
Now the issue is tftp client send request on dynamic udp port. Can anyone
give some idea, how i can bind the fixed port for client udp requests ?
Otherwise i hope, it is not a solution that i will open all port related to
UDP in the firewall.
