How to detect whether running on VMware?
by tony＠softins.clara.co.uk 25 Jul '08

Does anyone know how a program, script or shell user can best determine whether the machine is running on bare metal or is a VMware guest? Cheers Tony -- Tony Mountifield Work: tony(a)softins.co.uk - http://www.softins.co.uk Play: tony(a)mountifield.org - http://tony.mountifield.org

Re: [CentOS] Re: 6TB SCSI RAID vs. Centos

I'm using a Dell PERC 5/i with the drives configured as simple volumes (aka no hardware RAID). I beleive the PERCs are based on an LSI MegaRAID chipset/controller...

There is another way too, make the disk a raw PV (no partition table) and use LVM. LVM can handle PVs up to 2^64 in size. Then when creating LVs you only have to worry about what the max file system size is. -Ross ----- Original Message ----- From: centos-bounces(a)centos.org <centos-bounces(a)centos.org> To: CentOS mailing list <centos(a)centos.org> Sent: Thu Jul 24 22:04:42 2008 Subject: Re: [CentOS] Re: 6TB SCSI RAID vs. Centos I'll second that... we recently put a system online with over 3TB of storage.

Spamassassin as root and pyzor
by Hywel Richards 25 Jul '08

25 Jul '08

I've just set up a new mailserver using Centos5.2 (sendmail+clamav-milter+spamass-milter). I'm using the spamass-milter package from rpmforge (spamass-milter-0.3.1-1.el5.rf). I notice that the default setup is to run it as root. I set up my previous mailserver on Centos4, and I can't remember if I did anything special, but on that machine it runs as user "sa-milt". Is it safe/recommended to run spamass-milter as root? Does it in fact shed the root privileges or something like that when it actually does some processing anyway? Are there good reasons why I should leave it run as root (besides it being the least effort option)? I found a few discussions on this topic on the web but I have ended up confused and would appreciate some advice. Ideally I would like a link to a webpage entitled "How I learnt to stop worrying and run spamass-milter as root". Also, a related question: is it worth installing pyzor, or will spamassassin on its own be enough? I ask because pyzor doesn't seem to be in any of the main repositories. Thanks in advance, Hywel.

Missing SDLT600's
by Daniel Bird 25 Jul '08

25 Jul '08

Hi All, I have a CentOS5.2 server using a Qlogic QLE220 HBA, connected to Quantum DX30 and M1800 libraries via a Qlogic SANbox 5600 switch. I've installed the latest (v8.02.14) drivers from Qlogic for the HBA The issue I have is I am missing 2 of the 4 SDLT drives provided by the M1800 Library. The DX30 provides 6 drives, which are listed in dmesg and assigned /dev/st0->5. I would expect the SDLT's to be st6->10 but I only see up to st7 and dmesg only lists 2 Using the QLoigic SAN Surfer software all the LUN's/devices are visible to the host. FYI, I also have an old Sun220R connected to this same switch with a qlogic card; Solaris 9 has no trouble seeing all LUNs and devices. I've "googled" for a fair while and have not see anything that helps. My FC knowledge on CentOS is limited so any help with troubleshooting this would be greatly appreciated. TIA Dan

pptp server configuration
by Ramon Nieto 24 Jul '08

24 Jul '08

Hello all, i'm using the poptop server with centos 5.2 to give the vpn service at the company i work for. Some people are using the same account to use the service. 've been searching in google and the poptop site but i have not found any information about blocking multiple connections using the same account. The goal is to restrict only one connection per account. Any suggestions or pointers to documentation will be really apreciated. __________________________________________________ Correo Yahoo!
