Kickstart with all the latest updates?
by Alfred von Campe 05 Mar '07

05 Mar '07

Currently, I kickstart my machines over http to install CentOS 4.4 and then in a script called from %post do a "yum -y update" to install all the latest updates. Is there a way to set up the kickstart server so that I can do this all in one step? In other words, is there a "supported" way to roll in all the updates into the kickstart server? In case it matters, I set up the kickstart server by copying the contents of all CentOS 4.4 CDs (well, from the ISO images actually) into one directory, and then configuring the kickstart file to point to that URL (via http). Thanks, Alfred

That's actually intriguing. I think I'll try it out sometime. In any case, the ping solution provided by Dennis will meet my needs in this particular case. Thanks to you both. === Al

RE: [CentOS] Lame question about cp

Try this: \cp from to IIRC, cp is an alias that translates to cp -i, I believe rm and mv are the same. Entering the leading \ overrides the alias. Hope that helps.

CentOS 4.4 not seeing all RAM
by Kanwar Ranbir Sandhu 05 Mar '07

05 Mar '07

Hi Everyone, My server is only seeing 4.8 GB out of 6 GB available. I don't know why. I have a CentOS 4.4 x86_64 server running on a Tyan s2895 with 6 GB of RAM (two 1 GB sticks and 2 2 GB sticks). I upgraded the RAM, powered up the server, and when CentOS was finished booting, checked the available RAM with free. This is what it's reporting: total used free shared buffers cached Mem: 4809064 4769492 39572 0 197156 3127704 -/+ buffers/cache: 1444632 3364432 Swap: 2064376 176 2064200 The BIOS sees all of the RAM. In fact, it looks to me like the kernel knows 6 GB is available. But, it is only using 4.8 GB because I see this in dmesg: Memory: 4808464k/6291456k available (2106k kernel code, 0k reserved, 1299k data, 196k init) What happened to the other 1 GB+ of RAM? BTW, the server isn't running all the newest updates, but it is running the latest CentOS 4 kernel (2.6.9-42.0.10.ELsmp).

Sending traffic through Secondary IP Address
by Al Sparks 05 Mar '07

05 Mar '07

I have set up a secondary IP address in the same network as my primary. So eth0: 192.168.100.29 netmask 255.255.255.0 eth0:0 192.168.100.45 netmask 255.255.255.0 And indeed when I invoke an apache instance that listens on the secondary IP address/interface it works, and it also makes it outside the LAN since the default gateway is defined in the routing tables for 192.168.100.0/24. But I'd like to be able to send out some sort of broadcast on the network from that secondary interface so that the arp tables on various devices on the network get updated. How would I, say, use nmap to do something like that? Is there a generic way to force a particular program to use a secondary IP address instead of the default primary? Obviously, something like BIND or Apache httpd has that hardcoded in so that you can tell them to use secondaries via their configuration files. But how about those programs that don't? === Al

Virtualisation
by Stephen Harris 05 Mar '07

05 Mar '07

I'm building a new server at home to handle most of my internal requirements (mail, news, dns, dhcp, backups being the biggies). I also want it to host a couple of virtual servers which are allowed incoming connections from the internet (mail gateway, web server, ssh server); these are virtual so if a hacker _can_ break in then they're limited as to what they can see. At present the virtual machines are vserver instances on an old FC2 box. I'm wondering what people recommend for virtual servers these days? CentOS 4 with a vserver kernel? Wait for CentOS 5 and use Xen? VMware? (Vmware is the heavy solution, but it does mean I could host a windows session if I wanted to). Or Solaris 10 and zones? Any thoughts? -- rgds Stephen
