I always use screen when running updates, installs, disk maintenance, etc. This way, if the ssh session dies for whatever reason, the command keeps going and I can reconnect to the session later. It's also useful to be able to start the run at the office and then reconnect from home to check on it. -- Bowie

RE: [CentOS] VMWare Server Install Problem
by Harry Sukumar 13 Feb '08

13 Feb '08

Dear All, Thank you all for sharing this information, I had to setup something very immediately and a friend of mine suggested VIRTUALBOX, so I went on installing virtualbox, to be frank its great free software. There was no hassle in Installation and pretty similar interface to VMWare Server. Does the same job as more secure and reliable I guess I will try your suggestion some time this week Once again thanks to every one Cheers Harry -----Original Message----- From: centos-bounces(a)centos.org [mailto:centos-bounces@centos.org] On Behalf Of Akemi Yagi Sent: Tuesday, 12 February 2008 10:42 PM To: CentOS mailing list Subject: Re: [CentOS] VMWare Server Install Problem On Feb 12, 2008 4:33 AM, Alfredo Perez <alfredoj69(a)rogers.com> wrote: > On Tue, Feb 12, 2008 at 03:43:38PM +1000, Harry Sukumar wrote: > > Good Day All, > > > > I have issues installing VMware Server on CentOS 5, its asking for the > > location of c header files, i have installed them all but i am still > > unable to install VMWare Server > > > > here is the output > > > > What is the location of the directory of C header files that match your > > running > > kernel?

Question on failing hard drive part 2
by Jimmy Bradley 12 Feb '08

12 Feb '08

OK, I've figured out which drive is bad. Before I go any further let me give a brief HD configuration explanation. The primary IDE has a 80gig(Master) HD, and an internal zip drive(Slave) connected to it. The two 200gig Hard Drives are connect to a PCI ATA controller card(Not a promise card), one is master, the other one is slave. It is the slave 200gig drive that is going bad. Now, I have a feeling this would be too easy. When I set the machine up, Cent OS set the drives up using LVM. I only have about 20 to 30 gigs of data saved on the machine right now. Maybe not quite that much. Like I said, I have a feeling that hoping this will work would be too easy, but what do you think my chances would be, that I could disconnect the drive that is going bad, boot the machine up, and it fully boot up, and all my data be intact, and LVM automatically resize the home partition down to around 200gigs instead of 405gigs?

Interim RPMs for vmsplice() issue
by Erek Dyskant 12 Feb '08

12 Feb '08

Howdy all, I compiled a set of kernel RPMs with the upstream kernel patch applied. Obviously they haven't gone through the full QA process, but I know of them running on approximately 50 servers without any reported issues. They're available at: http://erek.blumenthals.com/blog/2008/02/11/rhel-5-centos-5-kernel-rpms-pat… Let me know any experiences you have with them. Regards, Erek Dyskant

Making FORWARD_IPV4=YES permanent / DHCP multiple routers
by Tim Alberts 12 Feb '08

12 Feb '08

First, I'd like to configure my system to forward ip, to act as a gateway for my network. I've always used a script during startup to do this: echo 1 > /proc/sys/net/ipv4/ip_forward iptables -t nat -A POSTROUTING -o ${UPLINK} -j SNAT --to ${IP_NAT} This works fine, however I want this permanent so I don't have to run the script on startup. I have the firewall setup with SNAT fine, but when I write the file /etc/sysconfig/network with the line 'FORWARD_IPV4=YES' it still doesn't enable the ip forwarding after boot? cat /proc/sys/net/ipv4/ip_forward 0 So how do I do this? Second, In DHCP, you can specify multiple DNS servers: option domain-name-servers 10.0.0.1, 10.0.0.2, 10.0.0.3; can you also do this with routers? option routers 10.0.0.1 10.0.0.2; so that if one is down, the network PC's can fail over to another?
