Re: Filezilla: GnuTLS error when using FTPES
I remember that no much time ago there was an incompatibility with Proftpd and Filezilla and I remember some other problems with these two programs. For example: http://forum.filezilla-project.org/viewtopic.php?f=2t=23101 I suggest you to search on Google for your specific problem to be sure that the cause is your computer, because maybe it is not. With gFTP or another ftp client does it work? best regards 2012/1/17 Ray Van Dolson ra...@bludgeon.org On Tue, Jan 17, 2012 at 04:27:52PM +0100, palmerlwatson wrote: When I'm trying to log in to a server via FTPS with Filezilla I get these FTP messages from the server: Response: 220-This is a private system - No anonymous login Response: 220 You will be disconnected after 60 minutes of inactivity.

Re: Move a SL6 server from md software raid 5 to hardware raid 5
Thank you for your answers!. Regarding to the backups I have an external backup system with bacula + tapes and another with NFS, so it should not be a problem. The problem is that I want to do all this process in a short period time to minimize the downtime. Be sure that your e-mails will be useful to me.

Re: Move a SL6 server from md software raid 5 to hardware raid 5
Doing it this way seems to be a high risk operation. Furthermore I want not do this because then I will have two raids: one raid per software (md) into one per hardware.. my thoughts are about copying manually the dirs of the operating system, then modifying configurations.. I think it is a more secure process. Thanks for the answer jdow ;) 2011/12/20 jdow j...@earthlink.net First take a complete backup of the md raid. Then if the laws if Innate Perversity of Inanimate Objects you'll be able to move the disks and have them just work. Your data is protected. (If you had no backup IPIO would, of course, lead to the transition failing expensively.) Even if IPIO does not work you restore from the complete backup to the same disks they were on after the hardware RAID assembles itself. (Despite the numerous times IPIO seems to work, I still figure it's a silly superstition. It does lead to a correct degree of paranoia, though.) {^_^} On 2011/12/19 09:18, Felip Moll wrote: Well, I will remake my question to not scare possible answerers: How to move a SL6.0 system with md raid (raid per software), to another server without mantaining the raid per software?

Re: PXE boot is an infinite reinstall
If you have Dell Servers there is an option that you can change through iDrac interface that is Boot once. You check Boot once with PXE and then reboot the machine. It will boot from PXE only one time so when rebooting will go throught the HD. Regards 2011/10/18 Yannick Perret yper...@in2p3.fr Steven Timm a écrit : The trick that Rocks uses is to have a boot order of (hard disk, pxe) and then when you want to reinstall, change two bytes in the boot sector to make the hard disk unbootable and it will fall through to a PXE boot only at that time. What worker node installs at Fermilab do is to have a DHCP server that only answers the PXE request when you want to reinstall, and no other time, so the PXE request just times out and then you boot off the hard drive. Here (at CC-IN2P3) we do mostly the same: boot sequence HDD;PXE. Destroying partition table works. We also use IPMI. Using IPMI commands (if your nodes have a IPMI-compatible card) you can use chassis bootdev pxe, whitch tells the node to boot on PXE only the next time. So reinstalling a node (with a configured IMPI) consists in chassis bootdev pxe + chassis power [cycle|on]. Regards, -- Y.

I searched the net and found many people with the same issue, but there was either no response or their solution would not work for my needs (requiring access to software I don't have). What I am after with this is a completely unmanaged automated install of a client on boot. I am using dnsmasq as my DNS, DHCP, and TFTP server. I have a server and a client. The client boots off the network card with PXE. It asks for and receives a IP from the DHCP server and proceeds with pulling the TFTP information. The TFTP server passes it a pxelinux.0 file along with the default configuration. The configuration has a kickstart file and the client continues with a flawless install of SL6.1. After the install, the client reboots...and the whole process starts over and over and over again. I know why it does this (the default boot option is to install), but I can't figure out how to control it. What I would like is a process where I boot the clients from an off state, have them do a fresh install, and then reboot into the new install. Nothing is stored on these nodes and a fresh install goes rather quickly so I don't mind this option. At first I tried scripting an option that just toggled the tftp default menu but it wasn't working very smoothly as not all my hosts boot at equal speeds. I attempted chainloading in the tftp but just made a mess and I didn't get any different results. Most likely due to me not understanding it properly. I am open to pointers. I thought I could do it inside of DNSMasq, but I couldn't find a good example and my attempts didn't work. I looked online and found projects like systemimager.org but I am already doing most of what they provide. I attempted to reverse their perl scripts but that is a bigger project then I initially thought. What I did like about this project was the ability to tell it to allow a single host or a group of hosts to reinstall or to boot off the hard disk. I have gotten some great pointers from this list so far and I am really hoping someone might have another for me. Any ideas? Thanks! ~Stack~

Re: Ypserv mknetid BUG
A lot of thanks Jean-Paul. Following your indications I checked out the passwd file. All of the entries had six : , but at the end of the file, there was a blank line!. I deleted the blank line and the problem disappeared. It's good to know this but the Ypserv developers should take care of these cases and instead of generating a sigsegv, they should warn the user with an error. I will check new versions of Ypserv and report the bug to Ypserv developers if it's still present. Problem SOLVED. Thank you.
