Logwatch verbosity
by Timothy Murphy 22 Sep '10

22 Sep '10

I'm getting literally hundreds of lines in my daily logwatch (under Centos-5.5), reading --------------------------------------- NULL security context for user, but SELinux in permissive mode, continuing () --------------------------------------- These began when I started running fail2ban (with shorewall), though that is probably a coincidence. In any case, what does this line mean, and is there any way of stopping it (short of stopping selinux)? -- Timothy Murphy e-mail: gayleard /at/ eircom.net tel: +353-86-2336090, +353-1-2842366 s-mail: School of Mathematics, Trinity ollege, Dublin 2, Ireland

Recompiling CentOS's stock openssl
by Al Sparks 21 Sep '10

21 Sep '10

I'm running CentOS release 4.8. For security reasons, I have to modify openssl's ssl.h in /usr/include/openssl/. That's easy. But for the new settings to take effect, I have to recompile openssl. I do have openssl-devel installed. How do I recompile? === Al

Hi, My storage admin just assigned a Lun (fibre) to my server. Then re scanned using echo "1" > /sys/class/fc_host/host5/issue_lip echo "1" > /sys/class/fc_host/host6/issue_lip I can see the scsi device using dmesg But mpath device are not created for this LUN Pleas see below.

using NUT on centos 5
by fred smith 21 Sep '10

21 Sep '10

Hi! Trying to set up NUT on Centos 5 to monitor a CyberPower 1500AVR UPS. There seem to be many documents, all of which seem to be not fully consistent with each other, and most of them aren't up to date. I'm guessing I should be using udev rather than hal, but I'm somewhat stumped on how to figure out what device it should be monitoring. there are a bunch of udev rules installed (in /lib/udev/rules.d/52-nut-usbups.rules) but it's not at all clear to me what, if anything, I'm supposed to do with them, or how I cause udev to see them there and do its thing. there's a document at http://fedoranews.org/contributors/kazutoshi_morioka/nut/ but it doesn't show how to do it with a USB device, only serial. so I decided to move on and see if it could be made to work without that understanding, using whatever I could figure out using the INSTALL file that comes with NUT. And that isn't geting me anywhere, so far. If anyone out there has had success at setting up NUT on Centos 5 (or RHEL) and can offer any advice, I'd appreciate hearing from you. Thanks in advance! -- ---- Fred Smith -- fredex(a)fcshome.stoneham.ma.us ----------------------------- "For him who is able to keep you from falling and to present you before his glorious presence without fault and with great joy-- to the only God our Savior be glory, majesty, power and authority, through Jesus Christ our Lord, before all ages, now and forevermore!

Dear Sir, I have been struggling to get bold letters in informix for CentoS 4.8 and I came across your article on PCL Command Sequences and I felt you could help.

Sendmail TLS verify=fail
by Morten P.D. Stevens 21 Sep '10

Hi, I have a small question with sendmail and tls verification. The tls verify fails on our internal/external sendmail servers. For example: STARTTLS=server, relay=mx1.imt-systems.com [89.146.219.60], version=TLSv1/SSLv3, verify=FAIL, cipher=DHE-RSA-AES256-SHA, bits=256/256 STARTTLS=server, relay=acsinet12.imt-systems.com [89.146.219.42], version=TLSv1/SSLv3, verify=FAIL, cipher=DHE-RSA-AES256-SHA, bits=256/256 What's the problem? The sendmail tls certificate should be okay on both servers.
