Re: [CentOS] Suggestion for Server Room monitoring
Well, there are ALOT of options.. You got 1-wire for temperature.. thenyou use http://www.klein.com/thermd/for the software, get a usb or serial interface device for the sensors, then a couple sensors..http://www.hobby-boards.com/catalog/main_page.php has a good selection.. You can put a good system together for under a 100 i would imagine. Then you've got the ready made systems: http://www.itwatchdogs.com/ http://embeddeddatasystems.com/page/EDS/PROD/HA/HA7Net with http://forums.cacti.net/about13526.html The route I am taking is the 1-wire one, so I dont have alot of information ont he others.. the Ha7 product is just a ethernet device for the 1-wire interface. It communicates to the Cacti install of the monitoring server.

Can you elaborate some more on the application in question and the problem you are experiencing. Typically network applications reuse the ports they are registered on, and if they didn't the only way to reuse them would be to kill and restart the process, so it may be that that isn't the problem after all, but more information is needed. -Ross __ This e-mail, and any attachments thereto, is intended only for use by the addressee(s) named herein and may contain legally privileged and/or confidential information.

The replication for the jobs will fail and in the StoreGrid replication server, the socket connection remains open and the replication server thinks that the replication job is still running. Please check if there are open socket connections from the backup server in the replication server. In the next replication schedule, the application will try to reset the active status in the replication server. If the resetting of the replication active status completes successfully, then the backup server will continue the replication. In the subsequent schedule the active replication status will be reset and Backup Server should proceed replication without any issue. In the current version , you can workaround this issue by setting the idle socket timeout value in the replication server's NAT/router setting. By doing this, the backup server idle socket connections will be automatically closed by the replication server's NAT/router. Currently there is no socket timeout value for the idle sockets in the replication server. We do have plans to do this in our future release. As a workaround, please try restarting the replication Server once and see if still the replication is in progres -Thats a quote from the tech support folks.. So every 12-14hrs I go into my replication server, shut down the services and restart them after the netstat shows the ports are closed.. and we carry on..

Re: [CentOS] Kernel Upgrade and RAID Card
nate wrote: Ryan Nichols wrote: and if i go back to grub take the old kernel its happy.. werid.. Sounds like you should just stick to the old kernel, what's in the new kernel that you need anyways? Is the system in a secure place?(e.g. separate firewall protecting it, not directly on the internet, don't have untrusted users logging in). If so, then you really have little to worry about, there is not much interesting things released in the newer minor version releases of the kernel in RHEL/CentOS. It's that way on purpose. In my experience having all your systems completely up to date is rare. The environment I stepped into a few months ago for example is running RHEL 4 Update 1 for the most part. They still run windows 2000 on several systems, and I don't think they've patched them recently. But the nature of the environment and the users that interact on it don't keep me up at night like a system directly connected to the internet with untrusted users. It'll probably take me the next 6 months to get everything more up to date in this particular environment, it has a lot of interdependencies. And by that point it should be easier to manage going forward, but we'll still probably won't install updates sooner than a month or two after they come out in general because that stuff takes time to test and deploy. Hopefully your not in a situation where you have untrusted users, if so you should replace the hardware with something that is better supported, or abstract the exposure to the system with something like virtualization, certainly not perfect but it's better then nothing, it will help dramatically against the most common, casual attacks. nate ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos We're trying to get support from a 3rd party software we use and they are insiting we goto the current versions of everything for there software before they'll move forward on the support.

to make this work because we already own it and it works until we
attempt an upgrade of the kernel .. So i guess its onto tech support

I am very very new to the linux world.. I am having problems with CentOS5.1 with kernel panics.
