Re: [CentOS] RS-485 over a half duplex serial in Centos 6.5
Hi Jason, I don't know what temperature range you want to sense. I have had success using I-Button temperature sensors directly on a USB RS232 connector. With this set up you can have multiple sensors on one line as each sensor has a unique address. The software I used for this was from a book Linux Toys by Christopher Negus and Chuck Wolber.

Sorry I am not a fully hardware guy so am a little lost at some of this stuff, but I know the software is not working since the hardware has no way to know how to interact through software.

In cases like this it is also useful to put in a line set -x early on

While you checking sensors from few machines, you can see the trend. Gotta think about changing the way of temperature monitoring here. Myself I wouldn't rely on internal equipment sensors to try to extrapolate ambient temperature from their readings. Most equipment will automatically spin their fans at faster RPMs as the temperature goes up which can give false indications of ambient temperature. I do monitor the temperature of network equipment, but also have dedicated sensors for ambient readings. Already saved us some pain once, opened up a new location in London last year and the ambient temperature at our rack in the data center was 85+ degrees F. The SLA requires temperature be from 64-78 degrees. Alarms were going off in Nagios. The facility claimed there was no issue, and opened up some more air vents, which didn't help. They still didn't believe us so they installed their own sensor in our rack. The next day the temperature dropped by ~10 degrees, I guess they believed their own sensor.. http://portal.aphroland.org/~aphro/rack-temperature.png People at my own company were questioning the accuracy of this sensor(there was only one, I prefer 2 but they are cheap bastards), but I was able to validate the increased temperature by comparing the internal temp of the switches and load balancers were significantly higher than other locations. Though even with the ambient temperature dropping by 10+ degrees, the temperature of the gear didn't move nearly as much. The crazy part was I checked the temperature probes at my former company(different/better data center) and the *exhaust* temperature of the servers was lower than the *input* temperature from this new data center. Exhaust temperature was around 78-80 degrees, several degrees below the 85+. It seems the facility in London further improved their cooling in recent weeks as average temperature is down from 78 to about 70-72 now, and is much more stable, prior to the change we were frequently spiking above 80 and averaging about 78. Also having ambient temperature sensors can be advantageous in the event you need to convince a facility they are running too hot(or out of SLA), as a tech guy myself(as you can probably see already) I am much less inclined to trust the results of internal equipment sensors than a standalone external sensor which can be put on the front of the rack. nate ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos +1 ChrisG ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

This can also be a customized .bashrc to set environmental variables etc. The line with the echo command is there so that you have a record of the password generated for each user.

I has, nevertheless, an interesting feature: 128MB of cache with battery backup. I launched the CentOS boot DVD and CentOS correctly identified the card and the RAID 5 array as configured by the controller's BIOS. My question now is: what would be the better way to implement RAID 5 on this server? Should I use the detected array and respective driver or should I delete the array and go for Linus Software RAID? If both solutions are in fact Software RAID, is there any particular reason to prefer one of the methods? I know that Linux RAID will create a universal, more compatible array, readable on any Linux machine. But is there some other reason that makes it preferrable to use the SERVERAID driver provided by CentOS? Is it optimized in any way that recommends its use? Will the controller still make use of its cache and battery backup if configured as a plain SCSI controller with Linux Software RAID?

First, the '\' characters are unnecessary and confusing, except the
one that precedes the semi-colon.
Second, that won't work. Sed does not perform on files in place - its
output is sent to stdout unless it is redirected, and you can't
redirect it back to the original file. To do something this way,
you'd need a script that replaced the input file and used 'sed' to
generate the new one (and then the script would have to rename it).

I saved the contents of the previous .thunderbird file structure with tar and created a new mail account with the same details (name, isp, pasword, servers etc.) as the previous account. you should be able to untar the .thunderbird tarball into another place, and then basically just move the email files into place in the current ~/.thunderbird remember to note where the email is expected, and there will be files per folder and an index for each one called the foldername.msf - you want to get all those over to the new instance. Also, you might need to rename of the files if you now have new folders with the same name ( eg. inbox ) now having said that, before you do anything, check ~/.thunderbird for more than 1 directory called something random.default, and check the profiles.ini file in the same place. its possible you are just looking at a new profile, and switching over to the older profile will be all you need. And then you can work out howto get emails from one side to the other. Thanks Karanbir, I will work on this when I get back from work tonight. There are two directories something random.default. When profiles.ini is set to use the one created when I recreated my mail connection, Thunderbird starts up with none of my history (as expected). When I edit profiles.ini to use the other (older) setup and start Thunderbird it starts the wizard to create a new connection - so clearly something has been corrupted in that setup. I will try to copy the important data from there to the new setup. ChrisG ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

[CentOS] LIMITING NUMBER OF KERNEL VERSIONS RETAINED
Hi Some time ago there was a discussion on the above subject. I have scanned the past few month's mailing list archives and cannot find the relevant mail(s). Could somebody please repost the solution or point me at the correct resource. I would also appreciate advice on how to do this on a RHEL4 server being updated with up2date. Is it safe just to delete the old kernel and initrd files from the boot partition and the grub conf file?

When rebooting after this the system instruct me to re-configure the X11 configuration, when doing this using the gui screens provided I cannot select a screen but can select the nVidia card and then the nVidia driver. The configuration generated still does not work - I attach a copy of the Xorg.0.log generated. In this log there is a mention of using the GLX driver/module from nVidia. While inspecting /usr/lib64/xorg/modules/extensions I noticed a sub-directory nvida that contained a file libglx.so. I renamed the libglx.so file in /usr/lib64/xorg/modules/extensions and copied the file in the nvidia sub directory into it's place - and rebooted. The reconfiguration of X11 still would not allow me to select a screen and also did not work. I attach a copy of the Xorg log Xorg.0.log.2 where it seems as if the correct GLX module has now been found but without giving me a useable X11 configuration. Any suggestion on how to proceed from here would be welcome - if entails getting another graphics card please suggest a suitable card that will run without hassles. TIA ChrisG snip /snip Hi All, I have finally found the solution to the problem of the invisible mouse pointer - from a tip given to me by Chris from Tangent Systems.

From everything I can find it appears that the graphics controller on these motherboards (mine has the C15G nVidia chipset and the controller is recognised as a GEForce 6100). I followed Jim Perrin's instructions and downloaded and installed the nVidia driver from RPMForge and still have the same problem. My next step is to try to find a PCI or PCI express graphics card that is supported by Linux so that I can start using this server.

[CentOS] nVdia C15G chipset and GeForce 6100 on board graphix controller
Hi, Apologies for the long post - but I'm being driven crazy by this problem. A while ago I built a new server that is intended to serve as a Xen server running multiple DomU systems used a test environments for systems that I am working on. The host Xen system will be CentOS 5 as will some of the DomU systems. The systems will all be hardware virtualized. The motherboard uses the nVidia C15G chipset and the onboard graphix controller is recognised as a GeForce 6100. I am having problems getting the Video and mouse to work properly with CentOS 5 - both with as set of CD's downloaded when CentOS 5 was first released and with a DVD obtained from one of the local distro shops. The symptoms are that the Video is run in 800X600 mode and the mouse pointer works while the system is booting and while I am logging in to a GUI session. Once the login process has completed the mouse pointer disappears (is not visible at all). The mouse does however work as you can see changes to the Icons and menus on screen when moving the mouse around (blindly). The same situation obtains when running the system with FC7 installed. However when I boot the system using a Knoppix 5.1.1 live disk the Video resolution is 1024X768 and the mouse works properly. I attach the output of lspci and lsmod from both CentOS and Knoppix as well as the X86 Config file from Knoppix. Could someone please advise me on how to get CentOs to give the same results with the video and mouse as Knoppix.
