[CentOS] How to add virtio modules automatically to initrd in CentOS4?
Hi, I migrated a physical CentOS 4.8 server into a VM on a CentOS 5 KVM host. Everything works fine, I even can use the paravirt drivers for network and disk. However the required kernel modules are not put into initrd somehow. Of course I can call mkinitrd --with virtioblk ... manually but that's too easy to forget. I searched the web but I didn't find any similar reports... I found some references to /etc/sysconfig/mkinitrd/ but this doesn't work for me. So how can I make sure that the initrd always includes the virtio stuff? fs ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Create the recommended /etc/modprobe.conf entry
alias scsi_hostadapter${NUM} virtio_blk
and virtio_blk.ko will be picked up automatically. Not sure where
virtio_pci is a module dependency of virtio_blk.

[CentOS] Add default quirk to pm-utils (CentOS 5.4)
I've installed CentOS 5.4 on my new Lenovo Ideapad S12 (Atom-based 12 notebook) and need to add a quirk to pm-suspend in order for the laptop to actually go to sleep. There's a couple of quirks that work just fine so I really don't have a preference. I found several instructions but most of them have failed me because CentOS's pm-utils is too ancient. Newer versions come with a parameter that adds the quirk to hald automatically, the CentOS version of pm-utils does not have this function yet. I've tried adding a /etc/pm/ config.d/99local config file with DISPLAY_QUIRK_VBE_POST=true and a /etc/ hal/fdi/information/99local-pm-utils-quirks.fdi manually to no avail: ?xml version=1.0 encoding=ISO-8859-1? !-- -*- SGML -*- -- !-- Created by pm-utils -- deviceinfo version=0.2 device merge key=power_management.quirk.dpms_on type=boolfalse/merge merge key=power_management.quirk.dpms_suspend type=boolfalse/merge merge key=power_management.quirk.vbe_post type=booltrue/merge merge key=power_management.quirk.vbemode_restore type=boolfalse/ merge merge key=power_management.quirk.vbestate_restore type=boolfalse/ merge merge key=power_management.quirk.vga_mode_3 type=boolfalse/merge /device /deviceinfo But nothing seems to work. Running pm-suspend does not do anything, running pm-suspend --quirk-vbe-post puts the Laptop to sleep. Any ideas?

Re: [CentOS] Add default quirk to pm-utils (CentOS 5.4)
Nevermind, I found it. Had to add a second line to /etc/pm/ config.d/99local. It now contains the following: DISPLAY_QUIRK_S3_MODE=true QUIRKOPTS=true Whick quirk I pick doesn't make a difference, I found several that work. This one works just fine and the laptop goes to sleep when I enter start pm-suspend from a shell, close the lid, or select suspend from the klaptop menu.

Re: [CentOS] how does the bootup screen move the cursor around?
On Fri, Mar 19, 2010 at 10:18 PM, Frank Cox thea...@sasktel.net wrote: My question is, how does that happen? Does it write its own esc codes directly to the screen? If so, how does it know what terminal we're using and, therefore, what esc codes to send? Modern terminals aren't text-based devices like the ones that used to be connected as serial consoles on old refrigerator-sized mini-computers and mainframes. Instead they're effectively framebuffer devices and anything that looks like text-character drawing is done by the display chipset on the graphics card or built into the motherboard. Those in turn all have a common set of minimal operations that can be accessed before the full set of OS-level drivers is loaded and that are supported by all types of monitors, so the boot loader doesn't need to know what specific chipset or monitor you have available as long as the basic hardware is considered supported. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Re: [CentOS] Multipath and iSCSI Targets
Depends on the target and the setup, ideally if you have 4 NICs you should be using at least two different VLANs, and since you have 4 NICs (I assume for iSCSI only) you should use jumbo frames. Jumbo frames should only be used if your CPU can't keep up with the load of 4 NICs otherwise it does add some latency to iSCSI. How much latency are we talking about? I'm looking into gigabit networks at for both home work and while home isn't so much an issue, work could be as I'm in the planning stages of setting up a gigabit network to allow some iSCSI NAS/SAN devices to back a bunch of VMware servers that we're due to get for our next refresh. -- Drew Nothing in life is to be feared.

That often depends on the NICs and switches, but in the realm of 10-15% off throughput.

Set it up jumbo frame capable, but start out with standard frames and if you see the CPU getting pegged, try interrupt coalesence, if that isn't cutting it use jumbo frames. -Ross ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

What's the best method to ban that ip [what is bruteforcig a server] what was logged on the logger? I need to ban the ip on the router pc. How can i send the bad ip to the router, to ban it? Just run a cronjob, and e.g.: scp the list of ip's from the logger to the router, then ban the ip from the list on the router pc? Or is there any offical method for this?

Both solutions are intended for the server and not for a remote host, however you could probably work around this with a small shell script. This does beg the question, why are you wanting to ban the IP's on the router box as opposed to the machine being targeted? The whole point of a router is to route traffic, not enforce firewall policy. This would be better handled by a firewall of all things, be it a hardware appliance (ASA, PIX, Juniper HSC) or iptables on the machine itself. You might keep in mind that the more firewall rules you add to the router the slower the network will become as all packets have to be checked against all rules.
