network mapping software
by Jure Pečar 19 Oct '11

19 Oct '11

Hi all, I'm looking for network mapping software that would walk the local subnet and using snmp/cdp/nmap & friends produce a picture of network connections for documentation purposes. I've seen some for wintendo, but haven't found any decent for linux and CentOS specifically. Something like cheops-ng.sf.net would fill my needs, but before I start a fight with 5+ years old code to get it compiled, I'd like to hear what you guys are using. -- Jure Pečar http://jure.pecar.org http://f5j.eu

Is there something that could have triggered this between 6.0 and 6.1? This server was updated to 6.0 CR around the same time this began happening, so I want to make sure if it's an issue in CR that I can file a useful bug report. When updating selinux-policy, do I have to update all the RPMs listed or will that one package suffice? Thanks - Trey

L9 - what is true?
by Jussi Hirvi 19 Oct '11

19 Oct '11

This code: boolean(null); ', '; boolean(string); ', '; boolean(integer);', '; boolean(array); ', '; boolean(map); ', '; gives: false, false, false, true, true This is different from L8. Is this intentional? If so, why? This has consequences which I think are counterintuitive: if(array(1) -> find('whatever')); This evaluates as true. - Jussi

Xfce from minimal install
by Johan Vermeulen 19 Oct '11

19 Oct '11

Dear All, because I have a lot of older machines and laptops (512Mb) I would like to use Xfce. So I installed CentOs 6 from the normal netinstall cd and selected minimal ( just over 200 packages). From there I enabled EPEL repo and did : #yum groupinstall Xfce after that I installed Xorg and the driver for Intel ( it's on a Dell laptop ) after startx I get a get a lot of gnome-session warnings; 'Unable to find provider 'gnome-panel' of 'gnome session: Pango warning ' and many more. So can anyone help me make further adjustments? thanks for any tips in advance. greetings, James Opensource Software is the future.

CentOS 6.0 i386 DVD
by William L. Maltby 17 Oct '11

17 Oct '11

Anybody have tricks to write the i386 ISO image to DVD? I've tried DVD+-RW, DVD+R, DVD-RW, DVD-R in both Windows 7 (two different writers) and rebooted into CentOS 6 (x86_64) and tried cdrecord (now called wodim). On wodim I've tried overburn, reducing speeds, etc. All give the same results: the same number of bytes are written - indicating the disc is full (according to my calculations) and wodim exits thinking it had a buffer underflow problem. I had no problem creating the x86_64 install DVD, which is smaller, and installing it next to my Windows. I just plug in a usb thumb drive and hit <ESC> when I want to run CentOS there and it works fine. The inability to create the i386 DVD initially prevented me from trying to install a desktop system on an old Acer running 4.8 (hasn't been booted in ... nearing a year?). I got around that by deciding to put the iso image on an external usb drive, exporting it via nfs and doing a network install. It had been so long since I dinked with any of this stuff it took me a couple of days of googling around, reading man pages, ... to get that working. Mostly having to do with iptables ports not being open. Sheesh! Black Hats create a lot of grief with their shenanigans! Anyway, then it panics when it starts writing the hard drives - I'll post another mail on that. Anyway, my life would've (will be) a bit simpler if someone can clue me in to how to get that image onto a DVD using either CentOS 6 or Windows. Checksums pass. Any hints gratefully accepted. TIA, Bill

I have and the drive in question is formatted and CentOS-6 is successfully installed using the same media if I employ a different system to do the work. > Also, if you put the old drive back, does it work? Yes, I can boot the Supermicro system from a previously formatted 500Gb disc that already has CentOS-6 installed on it. Further, if I install the 1Tb disk, now formatted and with CentOS installed courtesy of the other host, then the Supermicro system also boots from it. > What I'm looking for is whether you have a hardware > problem, either m/b or drive... or controller card. It does not appear to me to be hardware related, at least not directly. I suspect a bug in Anaconda. There are reports of a similar issue in Fedora last year and the bug was supposed to have been fixed in June of 2010, if indeed my problem is the same thing or something related. -- *** E-Mail is NOT a SECURE channel *** James B.

CentOS-6 install on 1 Tb drive fails
by James B. Byrne 17 Oct '11

17 Oct '11

I am attempting to load CentOS-6 onto a ST31000524AS 1Tb SATA drive in a Supermicro 5015A-EHF-D525 system. The BIOS sees the drive and the CentOS install process sees and initializes it as well. However, even when I accept the default partitioning, I get an error during the drive formatting prior to installing the OS. The error message is: "Could not commit to disk /dev/sda". I get this error whether the drive is configured as IDE or AHCI in BIOS. The advanced BIOS configuration section makes reference to LBA addressing and a maximum value of 137 Gb. However, I had previously equipped this very system with a 500 GB SATA drive and had not experienced any problems. Does anyone have any idea as to what might be happening here?

L9 - what is a value
by Jussi Hirvi 17 Oct '11

This code: var('i') = string; boolean($i); '<br>'; var('i') = array; boolean($i); '<br>'; gives: > false > true So an empty array gives "true" but an empty string "false". This is different from L8. Is this intentional? If so, why? This has consequences which I think are counterintuitive: var('i') = array(1); if($i -> find('whatever')); i 'true'; '<br>'; $i -> find('whatever'); '<br>'; /if; The if clause evaluates as true and gives as output: true array() - Jussi
