Intermittent problem, likely disk IO related - mptscsih: ioc0: attempting task abort!
by Jason Pyeron 18 Feb '15

NOTE: this is happening on Centos 6 x86_64, 2.6.32-504.3.3.el6.x86_64 not Centos 5 Dell PowerEdge 2970, Seagate SATA drive, non-raid. I have this server which has been dying randomly, with no logs. I had a tail -f over ssh for a week, when this just happened. Feb 8 00:10:21 thirteen-230 kernel: mptscsih: ioc0: attempting task abort!

Using a *supported* web cam under CentOS 5
by Robert Heller 17 Feb '15

17 Feb '15

OK, I plugged in a web cam device (something called a 'Zoomy' -- a web cam/microscope). It is recognized by the unc driver. Now what? Does there exist a program that can use this device? Or do I have to write one from scratch? I have been searching the web, but all of the links are about getting and installing *drivers*. I don't need a driver, I need a userland program. With Ubuntu 14.04, there is a program named Cheese, but I can't find a version that works with CentOS 5. And no, don't tell me to install Ubuntu 14.04! -- Robert Heller -- 978-544-6933 Deepwoods Software -- Custom Software Services http://www.deepsoft.com/ -- Linux Administration Services heller(a)deepsoft.com -- Webhosting Services

network automatically connecting on boot after new service installation
by g 17 Feb '15

17 Feb '15

2 weeks ago, i had my internet service changed from copper DSL to fiber DSL. now, every time i reboot, internet connection is automatically connecting on boot. before last update to 6.6, i could configure connection, now i can not bring up configuration window to disable auto connect. because of uneasy feelings about leaving computer up when i leave home, i disconnect 'bell line' so that when i am gone and have a mains failure and ups shuts down, i will not have internet connected when mains restore. also makes for uneasy feeling when retiring for night. :-) what do i have to do to change this? any and all replies / suggestions greatly appreciated. tia. -- peace out. in a world with out fences, who needs gates.

firewalld default policy = allow = no affect.
by dE 17 Feb '15

17 Feb '15

Hi! I'm running CentOS 7. Looking at the default policies of various zones, I've come to realize that only the drop zone has an affect, that's because this's the only one which drops unmatched packets.

Centos 7.0 and mismatched swap file
by Gregory P. Ennis 16 Feb '15

16 Feb '15

Everyone, I am putting together a new mail server for our firm using a SuperMicro with Centos 7.0. When performed the install of the os, I put 16 gigs of memory in the wrong slots on the mother board which caused the SuperMicro to recognize 8 gigs instead of 16 gigs. When I installed Centos 7.0, this error made the swap file 8070 megs instead of what I would have expected to be a over 16000 megs. I am using the default xfs file system on the other partitions. Is there a way to expand the swap file? If not, then is this problem sufficiently bad enough for me to start over with a new install. I do not want to start over unless I need to. Thanks for you help !!! Greg Ennis

setting up centos 6 x86_64 to relay through gmail
by Jerry Geis 16 Feb '15

16 Feb '15

I have setup my machine to relay through smtp.gmail.com installed cyrus-sasl-md5 cyrus-sasl-plain Added to access: AuthInfo:smtp.gmail.com "U:smmsp" "I:my accont" "P:my pass" "M:PLAIN" AuthInfo:smtp.gmail.com:587 "U:smmsp" "I:my account" "P:my pass" "M:PLAIN" Added to sendmail.mc the SMART_HOST smtp.gmail.com uncommented the pki lines define(`confCACERT_PATH', `/etc/pki/tls/certs')dnl define(`confCACERT', `/etc/pki/tls/certs/ca-bundle.crt')dnl define(`confSERVER_CERT', `/etc/pki/tls/certs/sendmail.pem')dnl define(`confSERVER_KEY', `/etc/pki/tls/certs/sendmail.pem')dnl set the confAUTH_MECHANISMS restarted sendmail It seems like sendmail is trying to use port 25 as the log shows "connection timeout". I did this to two other machines and it worked. the third one is being stubborn. Any suggestions to look at ??? Jerry
