Back up to Rackspace Cloud Files from a CentOS server
by Matt Arnilo S. Baluyos (Mailing Lists) 28 Mar '10

28 Mar '10

Hi all, I'm looking for a solution to be able to back up to a Rackspace Cloud Files account from a CentOS server. I have set up Duplicity but have found out that the back-ups are in GPG-encrypted volumes. There are also GUI clients for Windows and Mac but they're not what I need. I'm looking for something like a command-line tool that will let me push directories on the server (via rsync perhaps) to the Rackspace Cloud Files container. Being able to run it non-interactively on the shell is a requirement because I need to be able to run backup scripts via cron. Any help would be appreciated. Thanks. -Matt -- Stand before it and there is no beginning. Follow it and there is no end. Stay with the ancient Tao, Move with the present.

Network tuning for working with very old Solaris
by Wade Hampton 28 Mar '10

28 Mar '10

G'day. I am trying to get a very old Solaris 5.7 server to ftp data to my updated CentOS 5.4 server but the Solaris box keeps losing networking after sending some data. I can't ping the Solaris box from any of the servers on my network. Could this be related to a much newer (modern) TCP/IP stack in Linux and TCP options? If so, does anyone have any suggestions for how I can tune the Linux server? I am not as concerned about performance, but just to keep the Solaris box from crashing (and no, I can't upgrade the legacy Solaris server). Thanks, -- Wade Hampton

printer trouble - missing driver?
by Michael Klinosky 28 Mar '10

28 Mar '10

I can't get my HP DeskJet D2345 (USB) to work on my CentOS 5.3 machine. It'll work on another machine (with Fedora 7). I compared the installation details (in CUPS http://localhost:631) - seems that Cent does not have the driver. On the F7 machine, the device is "D2345 (HP D2300 series)" and the driver is "HP DeskJet D2300 Foomatic/hpijs". When I try to config my Cent machine for this printer, I don't see that driver anywhere in the list. I searched cups.org for D2345 and D2300 - no joy. Can I merely copy some file (the driver?) to the Cent machine? (If so, where would I find it?) Or, how do I get this printer to work with CentOS 5.x? * Details * On the Cent box, I tried using the "HP DeskJet" (generic?) driver. But, when I tell it to print (in an app or even a test page from cups), the computer seems to go thru the motions, but the printer doesn't respond at all (no noises, nothing). Indeed, cups even states that the job is completed. When I plug the printer into the Cent box, the message log reports: Mar 27 16:02:02 sr1220 kernel: usb 3-1: new full speed USB device using uhci_hcd and address 7 Mar 27 16:02:02 sr1220 kernel: usb 3-1: configuration #1 chosen from 1 choice Mar 27 16:02:02 sr1220 kernel: drivers/usb/class/usblp.c: usblp0: USB Bidirectional printer dev 7 if 0 alt 0 proto 2 vid 0x03F0 pid 0xC302 When I tell CUPS to print a test page, several lines are issued in the CUPS log; here are a few: I [27/Mar/2010:16:04:47 -0400] [Job 14] Started filter /usr/lib/cups/filter/pstops (PID 5297) I [27/Mar/2010:16:04:47 -0400] [Job 14] Started filter /usr/lib/cups/filter/foomatic-rip (PID 5298) I [27/Mar/2010:16:04:47 -0400] [Job 14] Started backend /usr/lib/cups/backend/hal (PID 5299) I [27/Mar/2010:16:04:49 -0400] [Job 14] Completed successfully.

httpd stopped working under SELinux so I had to turn SELinux off. libxml2.so.2: failed to map segment from shared object: Permission denied
by Aleksey Tsalolikhin 28 Mar '10

28 Mar '10

Hi. CentOS 5.4 64-bit with SELinux, happily running for over a year, suddenly httpd fails to start up, getting an error message like: Starting httpd: Syntax error on line X of /etc/httpd/conf.d/php.conf: Cannot load /etc/httpd/modules/libphp5.so into server: libxml2.so.2: failed to map segment from shared object: Permission denied I turned off SELinux and was able to start httpd. But what went wrong? And how to fix it and turn SELinux back on? SElinux labels on libxml.so.2.6.26 are OK ( system_u:object_r:lib_t ) and "restorecon -n libxml.so.2.6.26" does not return anything. No recent AVC denied entries in /var/log/audit/audit.log or /var/log/messages. I googled the above error message but all I could find were web pages in Chinese advising to run restorecon on libxml2.so file or turn off SElinux. Any suggestions? Thanks Aleksey

Re: [CentOS] RAID 5 setup?

Most suggest >RAID6 these days as a minimum, mirroring and striping appears to be >the most popular. I looked up RAID6 and see the addition or a parity bit. http://en.wikipedia.org/wiki/Standard_RAID_levels#RAID_6 RAID 10 is also something I looked at. Striped, then Mirrored So: 8 x 1.5tb = 12tb RAID 5 = 12tb - 1.5tb for parity data = 10.5tb space available RAID 10 = 4 x 1.5 = 6tb - 1.5tb for parity data = 4.5tb per stripe then mirror it. but with RAID 10, data is safe after many types of failures.

Multiple FreeNX servers and SSH ports
by Niki Kovacs 27 Mar '10

27 Mar '10

Hi, I've setup a small LAN of two desktops running CentOS 5 in a medical office. Both are connected to the Internet via a small modem/router. Recently I played around with FreeNX on my own desktop, and I'd like to install it on these two computers. On my PC, I just redirected port 22 in the router, so SSH (and thus FreeNX) requests from the outside get redirected to my desktop PC. (And yes, I have a strong password :oD) I'd like to handle the two PCs from the medical office remotely with FreeNX. I figured that the best way to distinguish them would be to assign a different port for SSH to each of them, and then redirect each of the ports respectively. 1) How do I choose different port numbers for SSH ? Any conventions or caveats for this ? 2) How do I configure these different ports ? By that, I mean : how do I tell SSH to use them instead of port 22 ? Cheers, Niki

Can anyone provide a tutorial or advice on how to configure a software RAID 5 from the command-line (since I did not install Gnome)? I have 8 x 1.5tb Drives. -Jason

non-root access to log files
by Carlos Santana 27 Mar '10

27 Mar '10

Hi, I would like to give read-only access to mysql and apache-http server log files to a non-root user. I can modify group or other permissions. But is there any other way you can suggest? Can I update it in user's home dir? -- CS.
