Mounting a Mac OS Extended (Journaled) Hard Drive
by Keith Beeby 22 Mar '10

22 Mar '10

Hi, I need to migrate about 8Tb of data from a Mac Fibre Channel RAID to by LVM Ext3 Linux Fibre Channel RAID. For speed I planned to connect both RAID's to my CentOS Server and copy the data directly. The Mac volume is formatted as Mac OS Extended (Journaled) it seems that CentOS 5.4 supports reading HFS volumes but not HFSPlus volumes. Is there a way of getting this volume to mount so I can copy of the data? I see Fedora has HFSPlus support Thanks Keith

VSFTPD accepting same user/session from different IP addresses

Hi folks, I have found the following in my logs: Wed Mar 10 15:52:33 2010 [pid 15232] [uploaduser] OK MKDIR: Client "195.200.70.*40*", "/04 LV gelieferte Daten 04_2010/04 LV Seiten/Jungz?chter" Wed Mar 10 15:52:33 2010 [pid 15231] [uploaduser] FAIL MKDIR: Client "195.200.70.*41*", "/04 LV gelieferte Daten 04_2010/04 LV Seiten/Jungz?chter" Wed Mar 10 15:52:36 2010 [pid 15232] [uploaduser] OK UPLOAD: Client "195.200.70.*40*", "/04 LV gelieferte Daten 04_2010/04 LV Seiten/Jungz?chter/Kooperationsseminar.doc", 23552 bytes, 13.89Kbyte/sec Wed Mar 10 15:52:37 2010 [pid 15231] [uploaduser] OK UPLOAD: Client "195.200.70.*41*", "/04 LV gelieferte Daten 04_2010/04 LV Seiten/Jungz?chter/Veranstaltungen der Jungz?chter im Jahr 2010.doc", 23552 bytes, 9.07Kbyte/sec Wed Mar 10 15:52:38 2010 [pid 15232] [uploaduser] OK UPLOAD: Client "195.200.70.*40*", "/04 LV gelieferte Daten 04_2010/04 LV Seiten/Jungz?chter/Foto Kooperationsseminar von laura weber.JPG", 13445 bytes, 9.90Kbyte/sec What I am concerned about is the fact that the client sends out using various gateways at once. Is there some configuration item in VSFTPD which can prevent this and reject packets from the additional ip addresses? Any hint or help is appreciated. Dirk

Re: [CentOS] Looking for experiences with filesystem choices....

So I tried XFS last night and it cut my copy times down substantially, so I need someone to verify that XFS in centos 5.4 has barriers enabled by default, I am not using LVM just the old fashion partitions and mount points. It appears that reading from the centos wiki that xfs is enabled in the kernel due to upstream vendor doing so for the first timeI loaded up xfsprogs and xfsdump but it was not clear about the barrier details.... Thanks...in advance. :) On Mon, Mar 22, 2010 at 9:26 AM, Brent L.

sendmail sending out on port 587
by Gregory P. Ennis 22 Mar '10

22 Mar '10

Dear List, I recently spent some time out of the USA, and found myself in a hotel that blocked port 25 which prevented my laptop's ability to connect to my office mail server. I did a scan on the internet and made the observation that this was a common problem. I had port 22 available so I was able to get my office server set up to accept mail on 25 and 587 without difficulty. The command "telnet mail.server.com 587" to my office mail server connects without difficulty. However, I have not been able to get sendmail on my laptop to connect to sendmail on my mail server at home using port 587. I have added the following to sendmail.mc on my laptop without success : define(`RELAY_MAILER_ARGS', `TCP $h 587') define(`ESMTP_MAILER_ARGS', `TCP $h 587') I finally made it back home, but have decided to change my configuration to use 587 by default so that this problem will be avoided, but I have been unable to get my laptop to connect. Anyone having ideas would be appreciated. Greg Ennis

how does the bootup screen move the cursor around?
by Frank Cox 22 Mar '10

22 Mar '10

While rebooting my computer after installing the new kernel a few minutes ago, I got to wondering about how the initial bootup screen (after grub, before rhgb) is constructed. The "Loading kernel blah blah blah" lines start at the top of the screen and proceed to scroll down as one would expect. But "kernel alive" shows up at the bottom of the screen and then more write-up is printed above it. My question is, how does that happen? Does it write its own esc codes directly to the screen? If so, how does it know what terminal we're using and, therefore, what esc codes to send? Further into the boot sequence something like ncurses could do the heavy lifting, but I don't think we're that far along yet. -- MELVILLE THEATRE ~ Melville Sask ~ http://www.melvilletheatre.com

Looking for experiences with filesystem choices....
by Tom Bishop 21 Mar '10

21 Mar '10

Lots of opinions out there and I have read and read, so I have a home server that I have finally setup with a hot swap hdd cage and what I am planning on doing is copying my data drive every other day and rotating them offsite, haven't figured out how often though. So I did my first test last night and the backup drive was formatted with ext3 but looking to try to speed things up and was wondering what would be my best choice. Most of my data is on VM's and the hdd files on some of them are quite large, I have used JFS and reiser in the past and was leaning on going with JFS but am tempted to look at XFS. So what I was wondering are what are folks experiences (instead of opinions) with different filesystems and while I want speed it needs to be reliable since it will be my back up data....running centos 5.4 x64 Thanks in advance...

How to add virtio modules automatically to initrd in CentOS4?
by Felix Schwarz 21 Mar '10

21 Mar '10

Hi, I migrated a physical CentOS 4.8 server into a VM on a CentOS 5 KVM host. Everything works fine, I even can use the paravirt drivers for network and disk. However the required kernel modules are not put into initrd somehow. Of course I can call "mkinitrd --with virtioblk ..." manually but that's too easy to forget. I searched the web but I didn't find any similar reports... I found some references to /etc/sysconfig/mkinitrd/ but this doesn't work for me. So how can I make sure that the initrd always includes the virtio stuff? fs
