Not specific to CentOS but I know you guys would be really helpful anyhow. Basically, I have a file which has been editted in the past very similarly to the hosts file only now I want to use it as a hosts file and need to run some fancy sed to massage the data into shape. Currently, the data in the file is in the form of <ip address> <tab> <short hostname> <space>

I'm looking to acquire a few new core switches for our network which would be a major upgrade from the cheap unmanaged things we currently have. Basically, just users, servers, and other simple network devices will be plugged into them but I'd like to start doing some testing with iSCSI for various non-production reasons. I have no allegiance to a particular vendor although I do have a

I'll be setting up a vSphere 4 environment hosting CentOS 5.4 on Netapp FAS and was curious how you guys are handling the automation of partition alignment within your linux guests. I'd like to use cobbler for dynamically creating kickstart scripts and wasn't sure if I could align my disk during install some how. Are there kickstart arguments to force the alignment on a 4k boundary?

Not a CentOS specific question, although I am running grep on CentOS 4.3 but how would you grep out a series of lines in a file starting at a specific point. For instance, if I have a file named foo and I want to grep out the next 5 lines after the first and only instance of the string "bar" how could I pull that off? Thanks so much.

This is completely off topic but just curious if you guys had any extra insight into what time today Firefox 3 will be released.

We have two virtual machines on ESX 3 running CentOS 4.3 and we'd like to turn them into some sort of highly available nfs file server. Currently, I am familiar with DRBD and RHCS but I was curious what others might recommend in such a situation. I'm not sure how easily we could use RHCS in such a situation because we don't really have the advantage of shared storage in this setup.

Just installed CentOS 5.1 on VMware ESX and am attempting to play with the newly added tick_divider feature. It doesn't seem to be making any difference in the number of timer interrupts though. I set tick_divider=10 which should reduce the number of timer interrupts to 100. I wrote a nasty little scripts that queries /proc/interrupts every 1 second and still see an increase each second in

We are in need of a remote mirror that provides rsync capabilities for vaulted centos releases. Specifically centos 4.3 but we'll need 4.4 when it is vaulted too. Any helpful links to information on this or a reputable mirror would be fantastic. Thanks.

Hello, we are running CentOS 4.3 and the latest cluster suite packages from the csgfs yum repository for this release and need to delete a cluster member. According to the documentation we need to restart all cluster related services on all remaining nodes in the cluster after the node has been removed. This is a four node cluster so removing one node obviously degrades the cluster to three

In centos 4 we used tail in the following way: tail +83 file That would tail the contents of the file starting at line 83. In centos 5 that same command complains about the file +83 not being found. It appears that the + option in tail doesn't work the same way in centos 5. Is there another easy way to grab the contents of a file starting at a certain line number and beyond.

We are in need of some very basic software that will give us the ability to swing an ip address from one host to another during controlled maintenance or host failure. For now the IP address will be the only resource that is shared and there will never be a need for shared storage. Eventually we may want to monitor processes for health (probably just read in pid file) and it would be great if

Not sure if I'm overlooking this somehow but is there a yumgroups.xml file for the [base] repository in CentOS 5? I've checked a few mirrors and didn't see it and a `yum grouplist` with only the base, updates, and extras repositories enabled looks like this: Setting up Group Process Setting up repositories base 100% |=========================| 1.1 kB 00:00

We have a very decentralized user base with no standard operating system or utilities except for a web browser of some kind (no Exchange either). What recommendations does the list have for software to coordinate conference room reservations? It doesn't need to be responsible for any kind of invitations or email notifications, really just a pretty calendar where scheduled events can go. It

Would any of you be comfortable running the drbd packages from the extras repo? If so, any particular version .. I notice 8.0, 8.2, 8.3. I'll do my own due diligence but just curious if the list has any implementation based feedback. Thanks.

I want to use helpers inside a controller method for an AJAX application. After the page is loaded and displayed, there will be an asynchronous javascript request to load additional resources such as html forms and other data. The controller which handles the request will collect the resources and send them back in json format. def get_resources data=Hash.new data[:form1]=form_helper1()

Hi all - there''s a patch I need to apply from a ticket: http://dev.rubyonrails.org/ticket/8798 The ticket appears to be stalled on the lack of a test case. I figured I''d just whip one up, but because it''s an Active Resource thing, and the test case would need to do ModelName.find(:all), I''d need to either mock the network connection or set one up. In this

I have installed Asterisk before w/ no issues but while trying today (1.6.2.13 and centors 5.4) I receive the following at the CLI: The configure script must be executed before running 'make'. **** Please run "./configure". Any tricks on getting through this? I did not select to libpri or zapata. only asterisk as i am building a voip only design on rackspace.com

Campers. Dr. Nic. The new migrations in Camping''s trunk are very nice. They also open the door (just an inch) to using Dr. Nic''s Magic Models with Camping. Here''s my stab at ''er: http://require.errtheblog.com/camping/blog.rb Run that against Camping trunk. Don''t forget to `sudo gem install dr_nic_magic_models`. The hackery is in

For anyone interesting in some meta-programming ideas, I''ve written up a short explanation about the Class Creation feature of Dr Nic''s Magic Models. I know most forum posts start with "How do I..." but thought it might be interesting reading for the ppl who answer the forum posts that start with "How do I..." :)

Hi all-- A quick question about the dr () function. I am using this function to reduce the dimensions of a data set I have that involves 14 predictor variables and one predictant or response. The goal is to discover which variables play the most important role in determining the response and, thus, to reduce the variables. I would like to use the sliced inverse regression method (SIR) within
