This reminded me of a recent issue doing just what you are asking about. I had an issue with sending traffic out an aliased interface on a bonded interface a few weeks ago. I needed certain traffic to look like it was from the aliased interfaces IP so the ACL on the receiving side would allow posts. But ALL traffic was still looking like it came from the real interface's IP address. and this caused the ACL to deny it.

So I tried moving the GATEWAY clause into etc/sysconfig/network and out of the individual ifcfg-eth? files. It works.

Since my switch *does* support 802.3ad, including layers 2,3 and 4 hashing, should I use mode=4?

It can deny access to any service that uses hosts.deny if you change it to ALL instead of sshd. It is configured to watch /var/log/secure, so if smtpd logs login failures there, then it can be used to add to the deny list. Apache does not use hosts.allow or hosts.deny by default.

Re: [CentOS] CentOS 5 x86_64 install does not see SATA drives

Currently I am running CentOS 4.7 i386 and it sees both drives but when I boot into the CentOS 5 install CD it fails to see the drives. Does anybody have any tips for getting the drives visible? I have a SuperMicro 6015P-TR that I just installed CentOS 5.2 x84_64. I struggled for 2 days trying to get the HostRAID RAID 1 working. I was only able to get 5.1 to install but not 5.2 (supermicro only has 5.1 drivers on its site). After the install, the server saw each drive individually sda, sdb rather than as one device and quit working after installing updates to the latest kernel. I googled around for answers and there was very little useful information available in getting this to work. In the end, I just bought a 3ware 9650SE-4LPML after hearing good things about these cards on this list, installed it one of the PCI-Express slots, pulled the cable to the drive backplane on the mobo and plugged in right into the card and installed C5.2. Worked like a charm. Rick ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
Re: [CentOS] Automount CIFS share in CentOS 5.1
Joseph L. Casale wrote: I am looking online trying to find a procedure to automount a CIFS share but need to use username/domain/pass in the credential file thats referenced in fstab. Its not working, anyone know of a resource that works in CentOS5.1? If it matters, the unc has a dash and a $ in it, and the password has special characters in it. This works for me using a credentials file: username=DOMAIN\hostname password=password I know the $ doesn't make a difference because I mount my AD homedir that has a $ at the end, I don't think the dash would make a difference but I'm not a 100% positive.

[CentOS] Kickstart install with a degraded raid array
Is it possible to install CentOS 5 with a degraded RAID 1 array using kickstart? I have the kickstart file already created but the server I want to use only has 1 hard drive in it at the moment. Until I can order a 2nd drive, I wanted to install the OS then once I received the replacement drive fix the array. I have seen instructions how to do this manually, but so far have not been able to get it to work using kickstart. Anyone tried this in the past?

For C5.1 see the first known issue: http://wiki.centos.org/Manuals/ReleaseNotes/CentOS5.1/ Rick Please note that the clock rate issue in that description applies to non-xen kernels. xen kernels are set to 250Hz by default. With this option you can reduce the clock rate from the default of 1000HZ to 100HZ which is desirable in a virtual machine. If it does not apply to xen then this should be made more clear.

[CentOS] Postfix Configuration Setup for 2+ domains
Hello, I have a client that wants to have a dedicated smtp sending host. But they have 2 separate domains then that don't want to have share IP address. The reasons from this is long and drawn out. Is it possible to setup postfix in a virtual host config, like apache for example, such that, domainA.com listens and sends on one IP address and domainB.com listens and sends on another address. This host is simply a email forwarding host, so no user accounts are on the server, they have about 5 servers serving websites for 2 domains and subdomains and want email coming from a common source for both domains (this will be the relayhost for the web servers). I have it setup to listen to 2 ip addresses but as of now I get: 220 smtp.domainA ESMTP Postfix on both addresses. Is there a way to have one address show as: 220 smtp.domainA ESMTP Postfix and the other: 220 smtp.domainB ESMTP Postfix More importantly, email send via 1 should look like it came from that domain and email sent to the other look like it came from its domain. I can find info on virtual domains, but its geared for receiving email for multiple domains. Thanks, Rick ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Re: [CentOS] Nagios on CentOS 4.5
Jason Ross wrote: First off I am a linux / CentOS newbies so go easy on me. Just curious if anyone out there is running Nagios on CentOS 4.5. I have now installed it on a second server due to issue but the issues have come back to haunt me. The OS is running on an IBM NetVista. Every thing in both installs is identical as are the problems. Once I have Nagios up and monitoring every thing hangs. Even a terminal will hang before it finally just locks up. The only thing that brings it back is a reboot. Even stopping the services doesn't work. Disk space seems fine and even during the hangs there doesn't seems to be anything taking up a tremendous amount of resources. After a reboot every thing works fine for several hours. Any guesses or suggestions? I am running on a C4 server here and haven;t experienced any issues with it. What version do you have installed and did you built it yourself or use a repo? I used rpmforge for the deps but built nagios by hand using the docs on their site.

Re: [CentOS] Clone physical into virtual
Scott Moseman wrote: Is there a formal, or preferred, method for importing a physical CentOS machine into a VMware instance? I know they make software to move Windows machines, but I couldn't find one to handle our CentOS servers. I have done something via scp/sftp in the past, which *seemed* to work, but if there's a better way I'm more than interested in hearing the process. What has worked for me is to use a liveCD to boot the image and then use ssh and tar to clone the machine to the virtual drives. You can find people suggesting netcat to do it but the ssh /tar method works because just about every liveCD has ssh and tar. Just mount the drive on the virt server say /mnt/newroot/, and if you separate images from from the image run: # ssh remote.box.com tar c / | tar x -C /mnt/newroot Adjust the tar attributes as needed.
