Upstream vendor's diskless vs LTSP
by Fajar Priyanto 19 Apr '08

19 Apr '08

Hello all, I have a customer that insists of using upstream vendor's diskless (system-config-netboot) rather than LTSP. The reason is that he wants to use a 100% packages from the vendor, not from LTSP or any other party. I try the vendor's diskless system, and although it's very simple to setup, it lacks the support and/or documentation whereas LTSP is very good in it. Another sample is that he wants to connect a scanner to the client, I doubt it can be, since there's no documentation about it at all from the vendor. Is there any fundamental difference between the two setups? Thank you. -- Fajar Priyanto | Reg'd Linux User #327841 | Linux tutorial http://linux2.arinet.org 15:38:01 up 8:32, 2.6.22-14-generic GNU/Linux Let's use OpenOffice. http://www.openoffice.org The real challenge of teaching is getting your students motivated to learn.

Not able to run kernel-xen with megasr module :/
by Tomasz Nowak 19 Apr '08

19 Apr '08

I've managed to install CentOS 5.1 on S5000PAL with fakeraid Intel Embedded Raid Technology II Raid1 (LSI chipset) with some help of kickstart declaration 'driverdisk --source=http://.../driver.img' Then I've had some problems with yum update - new kernel didn't know about megasr.ko. I've solved it with commands: cd /lib/modules/ cp 2.6.18-53.el5PAE/updates/megasr.ko 2.6.18-53.1.14.el5PAE/updates/ depmod -a 2.6.18-53.1.14.el5PAE mkinitrd /boot/initrd-2.6.18-53.1.14.el5PAE-new.img 2.6.18-53.1.14.el5PAE at last I've edited grub.conf add '-new' to initr definition. I'm not sure why I need to do that twice, but it finally worked.: # uname -r 2.6.18-53.1.14.el5PAE Now I need to install Xen, so: # yum -y install xen kernel-xen After installation I've tried the same command sequence: cd /lib/modules/ cp 2.6.18-53.el5PAE/updates/megasr.ko 2.6.18-53.1.14.el5xen/updates/ depmod -a 2.6.18-53.1.14.el5xen mkinitrd /boot/initrd-2.6.18-53.1.14.el5xen-new.img 2.6.18-53.1.14.el5xen vi /etc/grub.conf (add -new, etc..) BUT xen kernel won'ts start. Kernel panic, 'unable to mount root', etc. Am I missing something? Is it possible to make it work? -- Tomek

I was using pfSense in a vm under esx but I want to move to Xen and prefer something that can run as a pv guest. Anyone got any reco's of what can run on top of CentOS to perform a similar role as pfSense (perform nat/pat and firewall etc between two interfaces)? Thanks for any ideas! jlc
