Alternatively, I think it would work to use a USB stick to boot a recovery system remotely. Dell actually provides the ability to boot a remote CD over the DRAC interface but it's extremely slow unless you have a very high bandwidth connection, and at least a few years ago when I last looked, most people did not recommend using that functionality. Actually now that I think about it, I believe that if you have a CD/DVD drive with a self loading tray, it will suck the tray back in when the BIOS resets. This will not work with the slim drives with manual trays that they put in most servers, so you would have to have rack space that allows you to leave an external drive plugged in. The USB stick or other flash drive is probably a better solution. The main thing is having remote access to the BIOS.

[CentOS] Kickstart progress report?
When I'm kickstarting a CentOS5 machine, there's a progress report that shows how many packages have been installed so far, how many left, how much time it has taken, how much longer to go, and estimate for the total install time. Under CentOS6, I only get a report about packages (completed: N of M). Is there any way to add the time information back on CentOS6?

Do you mean plain old dhcp? If so, you just need the dhcp client package installed (dhcpv6-client-1.0.10-20.el5 under CentOS 5). This should be installed by default.

How to do it? If your networks are on different IPv4 broadcast domains (as you describe), you don't want a bridge. If you want bridged networking with KVM, your guests will be on the same network as the host. They'll use your existing DHCP services and routing.

The main network is out of my control and I cannot use its IP addresses. Bridging will require everything to have it's own IP address from the main network - which might work if it has DHCP service and available addresses. But you probably want NAT, where the guests have a private network space but outbound connections use the host's address. I've only done that with vmware and openbox so I can't help with the kvm setup but the concept should be the same. -- Les Mikesell lesmikes...@gmail.com ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

[CentOS] Best way to duplicate a live Centos 5 server?
I've got a CentOS 5 server that I want to migrate over into a virtualized instance. The problem is I need to minimize downtime so was trying to figure out a way to live clone the original. Initially, I thought I could do this via exporting an iSCSI target from the virtual host, create a MD raid 1 array on the C5 server, wait for it to sync, then shutdown the physical server and switch to the virtual one. But after getting iSCSI working... I realize I could not create a md device on a mounted disk. Unfortunately this old C5 wasn't setup with md raid 1 originally so I can't just add a the iSCSI target as an additional member for a triplicate. So I remembered DRBD was supposed to be used for replication. But after getting things set up, running the drbd-admin create-md command gave me this scary warning it will destroy data on the disk. Apparently because drbd writes meta data to the drive. So that appears to be a no go too. Am I missing something glaringly obvious here, or is the only way I'm going be able to migrate is to shutdown the C5 server for a few hours while duping the old drives? Would greatly appreciate any pointers how best to do this. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Have a tar file ready of the needed config changes ready and untar it and start up the new system... An interesting variation on this is to use 'ReaR' to back up and restore the machine, essentially cloning it but give the copy a different IP address as you bring it up. Then when the clone is close to ready to take over, shut down your apps for the time it takes a final rsync to fix up the differences (in the data areas only - avoid /etc/, (etc.), then switch the IP. ReaR is in active development now and is very usable. It is a set of shell scripts designed to run live backups that are capable of restoring to bare metal. It makes a new boot iso with tools from the running system to reconstruct the filesystem (including lvm/raid, etc.) and restore on top of that. Several backup methods are supported but tar to an nfs location is probably the easiest to set up. With a small amount of extra work you can tweak the filesystem layout, etc. if you don't want an exact clone. With hardware differences you might need to tweak modules and build a new initrd, too. ReaR is packaged in EPEL as rear. -- Les Mikesell lesmikes...@gmail.com ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Re: [CentOS] CentOS 6.2: suspending vim with ctrl-z and resuming with fg - stopped working
-Original Message- does anybody have an idea, why can't I suspend vim-enhanced-7.2.411-1.6.el6.x86_64 with a CTRL-Z, then execute few commands at my bash prompt and then get back to the vim session again with fg? If you just need to jump out to the bash shell and execute a few commands, why not use the 'shell' command that is part of Vi/Vim? Press the ':' key to get to the Vi ':' prompt, then type 'shell' and press return. This spawns a subshell, running your shell CLI, where you can execute the commands you wanted to run. To return to the Vi/Vim parent process, just type 'exit' at the shell's command prompt to close the session and return to Vi/Vim session. Works across most Linux and UNIX platforms, with both 'vi' and 'vim' Cheers! Simba Engineering ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
[CentOS] resource efficient log scanning tools
I'm looking for a logfile scanner that can search for regular expressions in logfiles and send immediate email notifications. I'd like to try to find something that doesn't use huge amounts of memory. I'm currently running fail2ban and used it to do some of this scanning, but I'm finding that it can suck up memory and CPU resources when there is a lot of logging going on. I am aware of swatch, but most people say that it is pretty resource intensive as well. I came across logsurfer in google search and was wondering if anyone has experience with it or what other good alternatives might exist. While fancy features are nice, I'm willing to forgo them for lower resource consumption. Thanks, Nataraj ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Re: [CentOS] yum problem with glibc
Timothy,
-Original Message-
The problem is that the server is a long way away (in another country)
and I won't have any way of contacting it if it stops running.
--
If your system is half-way around the world (or even half-way around the state),
you might consider investing and installing a KVM-over-IP device like one at
this site:
http://opengear.com/product-IP-KVM-spec.html
Not only does it provide direct access to a server's console via SSH (using AES
256-bit encryption), but it also allows you to mount a virtual CD/floppy/disk
to the console. Server sees the disk as USB-attached. The KVM-over-IP device
ensures that you can still talk to the server even if the network card, network
stack, or server operating system gets hosed. The SSH session is between the
KVM-over-IP device and your desktop machine, with a serial (or USB) connection
from the KVM-over-IP device and the server console (just like you were sitting
next to the server in person :-) -- the KVM-over-IP device can also be locked
down to permit SSH from a known set of IP addresses and/or subnets.
Or, if your server is running in a VPS, your cloud provider may be able to
provide you with out-of-band access to the virtual console of the server.
In the past, I have used a similar device ('iLO' built-in to the server) to
repair/rebuild a broken server on the other side of the country by booting it
from rescue media that lived as an ISO image on my desktop system. While the
link was slower than a direct connection, it still saved me two days in the
travel time I would have to spend to reach the physical server. My link to the
server was about DSL (512 kbps), so it was slow, but within reason. If the link
were slower, I would only use it for terminal access instead of using the
virtual media feature.
Cheers!
Simba
Engineering
PS. While it took me four times as long to do it, it was still cool to be able
to rebuild a server from the ground up without having to leave my desk :-)
