HP z3200ps printer ppd
by m.roth＠5-cent.us 22 Mar '11

22 Mar '11

Now that we've got the thing, does anyone know what ppd I can use for it? I've seen someone recommending: - the generic postscript ppd; - the hplips driver. I also see ppd's for a DesignJet 800ps, and ones for the 5000ps and 5500ps. Has anyone had any experience with any of these? mark

The overhead and instabilities of installing the components and configuring these features is adventuresome. Simply explaining to a client's inventory management that *they have to record the MAC addresses when they receive the hardware* so that the DHCP setups and network setups can be done gracefully has been awkward. For a few servers in a personal, or small business rack, it's not a big problem. But even the big hardware vendors can be very confusing to learn all the interface tricks and configurations for, and in a mixed environment it can get out of hand really, really fast. I've had a devil of a time demonstrating, and explaining to clients, why they need these tools, right up to the point when they say "but, but, but, I can do that with the Windows servers!!!!" and showing them, on the purchase orders and the emails, where they paid for that service and where they refused to allow me to install the drivers because that "wasn't part of the project". This has actually gotten *MUCH* better with "our favorite upstream verndor's" 6.0 operating system, and I'm looking forward to CentOS 6.0 with baited breath. The really cool features of IPMI have matured a lot, and in some cases no hardware vendor drivers are needed, It Just Works with the basic system installation. Unfortunately, I don't have a rack of hosts to test this on this week, or I'd suggest it.

What do you mean by refresh rate of the dns server? Like TTL length of records? Or..?

Need help in "repairing" the booting of my Linux 4 server
by Todd Cary 22 Mar '11

22 Mar '11

As I shared on this forum last week, I did a bad boo boo when I erased my /boot/ directory without a backup - all of the things I caution other NOT to do. Nevertheless, after trying to put things back in order, today I decided to try a reboot and I get a GRUB prompt. Next I have put my Linux 4 disk in the CD drive and have selected the "linux repair" mode which has put me into the /mnt/sysimage with the # prompt. That is as far as I have gone since I am in uncharted waters. Help! It, the linux repair, has found and identified that I have a Linux system...what should I try next?

mdraid on top of mdraid
by Emmanuel Noobadmin 22 Mar '11

22 Mar '11

Is it possible or will there be any problems with using mdraid on top of mdraid? specifically say mdraid 1/5 on top of mdraid multipath. e.g. 4 storage machines exporting iSCSI targets via two different physical network switches then use multipath to create md block devices then use mdraid on these md block devices The purpose being the storage array surviving a physical network switch failure.

> Since your exporting the storage as iSCSI, the host machine will see > it as a raw disk, irrespective of how it's setup on the exported > server. So, yes, you can do this. Sorry for my ambiguity, I meant that mdadm would be on the host machine. e.g. Using just a 2 node, raid 1 situation Storage 1 -> Disk exported on 192.168.1.10, 192.168.2.10 Storage 2 -> Disk exported on 192.168.1.20, 192.168.2.20 Host -> mdadm multipath md0 = 192.168.1.10, 192.168.2.10 -> mdadm multipath md1 = 192.168.1.20, 192.168.2.20 ---> mdadm raid 1 md2 using md0 md1

Admin stuff

Is there something odd going on? The question about the errors in mcelog just showed up *again*, and it's the original that I answered this morning. The question about something - was it the md? - original seems as though it's shown up more than twice today, with the same timestamp, I think. Is anyone else seeing this, or is it my host's mailserver? mark

syslog.conf - how to redirect messages by a program name?
by Alexander Farber 21 Mar '11

21 Mar '11

Hello, the "man syslog.conf" explains how to filter syslog messages by facility (auth, authpriv, cron, daemon, kern, ... ) or by priority (debug, info, notice, warning, ...). But how could I redirect messages by a program name, like "drupal" or "php"? For example I have in /var/log/messages: Mar 20 04:20:44 mysite drupal: http://mysite|1300594844|page not found|66.249.66.193|http://mysite/sites/default/files/pictures/picture-7133-1300462418.png||0||sites/default/files/pictures/picture-71333-1300462418.png Mar 20 04:20:50 mysite drupal: http://www.mysite|1300594850|page not found|93.158.148.31|http://www.mysite/viewtopic.php?f=5&t=42639&p=165661&sid=73944439da6ca3054a40f464ce97a628||0||viewtopic.php but I would like them to go under /var/log/drupal (and I'll rotate them later by adding a file to /etc/logrotate.d ....) Regards Alex
