Mouse problems
by Mace Eliason 10 Jun '06

10 Jun '06

Hi I am running Centos 4.3 and I having irratic problems with my mouse. I have the same problems with other versions of centos as well. I have search and tried everything that I could find but still it's not working right. It is a new microsoft laser wireless mouse 6000 For the most part it seems to work okay but it the buttons seem to click on there own a you move the mouse. For example if I click on the menu it drops down as long as the mouse is moving down the menu its fine as soon as I stop it loads what ever progam the mouse is on. Clicking has problems to some time you have to click serveral times to get it to work. Or you click a check box and when you move the mouse off the check box it un checks. I have check the X config file and it is set to what is suggested for usb mice. Any one have similar problems. If I plug in a regular optical usb mouse it works just fine. Mace

You "raw bps" will vary greatly depending on > your blocksize and other factors. I don't follow. The backup program is writing data to the device. Regardless of how complex that data stream is, there is a specific amount of data that is transmitted in a given period of time. This would be like sticking a meter inline on an ethernet cable and simply counting bits. There may or may not be a tool to do this and it may or may not be a useful measurement, but it should be possible. -- Bowie

I have a backup spooling onto a DLT drive. Is there any tool that will let me monitor the data throughput on the device? -- Bowie

I'm looking for a script or some tool that enables me to create custom iso's for centos 4.3 I'l also need tools to build some custom rpm's. What i want to do is create a cd that will install centos 4.3 fully updated (at the time of cd creation) together with self created rpm's of ispconfig.

shadow file question
by Feizhou 09 Jun '06

There is this * in the password field of the shadow file for certain accounts. I know that the ! is to indicate a locked account but what does a * mean? man 5 shadow does not reveal anything.

SuperOdoctor for super-micro
by Sam Drinkard 09 Jun '06

09 Jun '06

Rats... found some hardware monitoring from the vendor and it's broken, or I'm missing some pieces. No mention of CentOS specifically, but RH is supported, so figured it *ought* to work. I'm apparently missing a library -- liblinc.so.1, and a net search reveals several sources, both for x86 and 64-bit. Tried them both, after the x86 did not work, and the 64-bit I thought was going to work, but it crashes the application under gnome, and under text. Yes, I did the bad thing (tm) and installed an rpm not from yum, and now, I can't seem to make rpm remove it. Says it's not installed, but it is. Rebuilt the database and still says it's already installed when I tried to reinstall it, but says it's NOT installed when I try to remove it ...hmmmph. I know where the rm -f keys are :-) Question to the gang. Anybody have this software working on a supermicro board, and if so, what did you do to get it going?

mdadm raid 1 question
by William Warren 09 Jun '06

09 Jun '06

Does Centos 4.2 have the grub issue where the boot loader does not get installed onto both hard disks in a software Raid 1 environment? if so does 4.3 solve that issue? -- My "Foundation" verse: Isa 54:17 No weapon that is formed against thee shall prosper; and every tongue that shall rise against thee in judgment thou shalt condemn.

Intel Xeon and hyperthreading
by Sam Drinkard 08 Jun '06

08 Jun '06

Another question some of you may help me make decisions on. I've been doing some reading that indicates that having HT turned on in this dual xeon machine might actually slow down the computing process rather than speeding it up. I rebooted this a.m., and turned HT off, just prior to my main application run. One thing that might be of note, this application is using OMP for utilizing both cpu's, and prior to turning off HT, I had been running the software using 2 cpu's of the 4 that the OS sees. I'm waiting on a model run to finish to see if there is any appreciable difference, but the one thing I do notice right off is cpu utilization is running close to 100% on both, where before, it averaged maybe 50% or thereabouts. Again, sar is showing at last count, 83.56% utilization for user, 10.27% system and only 0.02% nice. Idle was 5.74%. I'm attempting to squeeze every last bit of processing power out of this machine, and would entertain suggestions on tuning if there happen to be any types of tuning that would help.
