Re: [CentOS] Installing 4.4 - problem on 386
by Jussi Hirvi 20 Jan '07

20 Jan '07

I tried installing with several options (noacpi noapm; noprobe; noprobe skipddc noacpi noapm nodma). Always I get the same error. BUT this is not in fac a CentOS problem at all, because I get the same error always when I boot from hd (Fedora Core), IF there is a CD in the CD-ROM drive. (I tried with CentOS 1/4, CentOS 2/4 and a HP printer software CD.) It must be something with the CD drive! Maybe I just have to try another CD drive. - Jussi H.

Today's Topics: 1. New members of the team (Johnny Hughes) ---------------------------------------------------------------------- Message: 1 Date: Sat, 20 Jan 2007 04:33:08 -0600 From: Johnny Hughes <johnny(a)centos.org> Subject: [CentOS-announce] New members of the team To: CentOS-Announce <centos-announce(a)centos.org> Message-ID: <1169289188.5425.3.camel(a)myth.home.local> Content-Type: text/plain; charset="us-ascii" I would like to take the time to introduce some new members of the CentOS team. We have added some new team members to better handle / respond to bugs.centos.org issues. They are: Stephen Smoogen (aka smooge on IRC) Matthew Miller Both these guys are regulars on the CentOS lists and are experienced at supporting distros, they will be a great asset for the CentOS Project. Also performing more duties is Ralph Angenendt (aka range on IRC). Ralph is our current wiki master and he has also decided to manage the CentOS mailing lists. We will be setting up and managing some "Alternative Language" lists in the near future (probably German, Spanish and Portuguese to start). We have also added an internal QA team with John Newbigin (CentOS-2 Developer), Ralph Angenendt and Stephen Smoogen to work on CentOS-5 QA. So, not only are we moving forward with CentOS-5 beta, but we are also gaining strength in other areas of the Project too. Thanks to John, Stephen, Matthew and Ralph for their commitment to donate their time and experience to CentOS. We will all be better for it. -- Johnny Hughes CentOS Developer

Preventing a user from moving "up" directories
by Todd Cary 20 Jan '07

20 Jan '07

I am in the process of setting up a new server. In the process I cannot remember what I need to set so that an FTP user cannot move upward in the directory tree of the user's directory. The FTP server is VSFTP. The user's directory is owned by the user and the permissions are 775. Isn't there a setting in httpd.conf to prevent that?

NFS 64-bit client crash with 32-bit server
by bigendian＠gmail.com 20 Jan '07

20 Jan '07

I have an unusual scenario where a new 64-bit multi-core Opteron Centos 4.4client crashes when writing a large file on a 32-bit NFS server. The problem happens on the same client with either Centos 4.4 or SuSE 9.3 32-bit NFS servers. Additionally the problem is reproducible with another identical 64-bit Centos 4.4 client. I'm not certain that the problem is tied to a 32-bit (as opposed to 64-bit) NFS server, but it doesn't happen on a local file system. The crash appears to be some sort of kernel panic, but I don't have the details as physical access to the server isn't easy. The crashes seem to happen when creating files over 2GB in size, but there doesn' seem to be a fixed size that triggers the problem. Sometimes I can get file sizes as high as 3GB before the crash, but it's ususally at the 2.3GB to 2.6GB range that it happens. Are there known issues with Centos 4.4 and NFS that I might be running into? Thanks, Tom

Question with MailScanner?
by Indunil Jayasooriya 20 Jan '07

20 Jan '07

Hi, I am happily running sendmail with MailScanner on CentOS 4.4. But I have an question. My question is that there are huge number of mails in /var/spool/mqueue.in . Why is that? My hard disk would go to waste. Can I delete them? or are these real mails. -- Thank you Indunil Jayasooriya -- Thank you Indunil Jayasooriya

The permissions are apparently set incorrectly on the vnc SRPM in the FastTrack repo on mirror; I get "permission denied" when I try to mirror it. Thanks. Josh Kelley

Problems w/ CentOS 4.4 ....
by William A. Mahaffey III 19 Jan '07

19 Jan '07

.... I just installed CentOS 4.4 yesterday P.M., on my 2.4 GHz P4 box, Foxconn i865 mbd, 2 GB DDR400 RAM (4 X 512 MB), 1 X 20 GB HDD (hda), 1 X 160 GB HDD (hdb), 1 X LG GSA H22N DVD reader/burner (hdc), 1 X 400 GB HDD (hdd), Coolmax CP500-T PSU. I wiped SuSE 9.2 off of the 20 GB drive & installed CentOS. The other 2 drives were already ext3 FS & will be mounted as /home & /work when I get everything sorted out & going. The install went smoothly, I installed as a server, plus added all of the developement stuff. When I removed the DVD & rebooted, everything was AOK, except that the booted OS apparently didn't see the DVD drive. When I put the DVD back in to add some more software, it never automounted, & I never could get it manually mounted. I pored through dmesg output (& posted to other lists), but no luck. I eventually came up with the following question: Since this is a relatively new burner, could it be that it is unsupported under CentOS 4.4 ? I also googled & searched the archives (manually) this A.M., but no say either way. Sooooooooo: what did I mess up so that CentOS 4.4 can't see the DVD drive that I used to install it :-) ? Thanks in advance for your time. -- William A.

http://www.net-dns.org/ and perl-Net-DNS-0.48-1 upgrade direction needed
by R Lists06 19 Jan '07

19 Jan '07

Greetings :-) On this particular production centos 4 mail server system if I rpm -qa | grep perl I get... perl-Filter-1.30-6 newt-perl-1.08-7 perl-DateManip-5.42a-3 perl-libwww-perl-5.79-5 perl-XML-Encoding-1.01-26 perl-Time-HiRes-1.55-3 perl-URI-1.30-4 mod_perl-1.99_16-4.centos4 perl-HTML-Tagset-3.03-30 perl-Parse-Yapp-1.05-32 perl-XML-Parser-2.34-5 perl-XML-Dumper-0.71-2 perl-libxml-enno-1.02-31 perl-Digest-SHA1-2.07-5 perl-Net-DNS-0.48-1 <------------- **** perl-DBI-1.40-8 perl-HTML-Parser-3.35-6 perl-libxml-perl-0.07-30 perl-Digest-HMAC-1.01-13 perl-5.8.5-36.RHEL4 right now I am focusing on perl-Net-DNS-0.48-1 and I want to figure out how to migrate to the latest version of Net::DNS on the http://www.net-dns.org/ website or learn if .59 has been rolled into the upstream and therefore to centos 4 or ??? i ask this as I am leary of upgrading production centos servers via CPAN I am looking to list wisdom to get some direction to help solve this one first please. I have researched the basics yet if I may please get a little help to continue going in the right direction I would be most grateful. I am sure I will want to add or upgrade some of the others as well. Ummm much of this is in relation to Spamassassin 3.1.7 issues Please chime in on creating a new RPM or using CPAN and any other ways that you folks are dealing with this pleasae? Thank you and kind regards - rh -- Robert - Abba Communications Computer & Internet Services (509) 624-7159 - www.abbacomm.net

John, I'm reading now some stuff of clustering from internet, thanks for your opinion, let me ask you, (maybe a stupid question), which are the common applications used on cluster's systems? Web?
