Wireless Made Easy (for Home Desktops)
by Ron Blizzard 02 Mar '10

02 Mar '10

For those of you who use a wireless router and may work on one or two (or even several) machines in your computer room, an AP Client is a nice solution. When you move to another machine you can just move the wireless net adapter to the new machine and you're up and running on the network immediately. I've been using a D-Link G730AP for a while -- but it's not really made for this -- it's a pocket adapter meant to carry with you laptop. And, unlike my old Asus WL-330, it won't hook up to a switch. Asus also makes a more powerful, larger, wireless AP/Client/Bridge/Reapeater, the WL-320gE. I bought two of these on eBay and they work great as Clients (network adapters) or "Stations" in Asus talk. They have a range of 850 meters (as compared to the pocket AP's range of 40 meters) so, in my room, I've got the full speed of my Cable wirelessly. It's three to four times faster than the D-Link G730AP, and it's solid (the D-Link was iffy). But, more importantly, I can hook it up to a wired (standard) switch and have as many simultaneous network connections as ports in the switch (in this case, four -- but I only use two). I've also set one up in the back of the house with a switch for my son's computers -- through several walls they're still getting very fast service. This is the only way I've used this device, but a lot of people buy them as repeaters. (I could mine up a repeater/client and my kids would have an even stronger single, but it's not necessary.) Another feature of Asus is that you can use it simultaneously as a bridge and as a wired client. It works well, the documentation is a bit inadequate, but it doesn't take long to "translate." Anyhow, I've rambled again. The reason I bring this up is that these things are currently selling for $25 on eBay -- which is about the cost of mid-range USB adapter. The seller has nearly 800 of them. (I have no relationship with the seller, except I'm a customer.) The eBay link is at http://tinyurl.com/ykysncw -- RonB -- Using CentOS 5.4

Virtual Machine Path Issue
by gene.poole＠macys.com 02 Mar '10

02 Mar '10

All, I'm running CentOS 5.3 x86_64 and I decided to install VMware Server 2.0.2 and all went without a hitch. I then created a Virtual Machine and used CentOS 5.4 x86_32 ISO image to build it. While I was customizing the built image, I attempted a 'find' command and received a message that the command could not be found. I checked root's path statement and found some strange entries (i.e. /usr/bini). Once I corrected those entries all seems to be working fine now. I don't have a physical platform to test the ISO on, so I must remain in the virtual arena. How can I tell if this is an error with the ISO or something going crazy during the VM build? Thanks, Gene Poole

kexec for CentOS 4?
by tony＠softins.clara.co.uk 02 Mar '10

02 Mar '10

I have a remote CentOS 4 machine on a network where I can't put a DHCP or PXE server, and I want to do a complete reinstall. So what I want to do is, from the currently-running system, to invoke an installation kernel and initrd in just the same way that GRUB would, giving it a boot command line that specifies a remote kickstart file, installation tree, and other required info. It looks like kexec is the right tool to do this, but I have only been able to find it for CentOS 5. Does anyone know where I could get kexec for CentOS 4? Does the CentOS 4 kernel support it? If not, are there any other ways to achieve what I've described? Thanks Tony -- Tony Mountifield Work: tony(a)softins.co.uk - http://www.softins.co.uk Play: tony(a)mountifield.org - http://tony.mountifield.org

Moving hard drives
by Slack-Moehrle 02 Mar '10

02 Mar '10

Hi All, I have a server that is running nicely, except I have hit the maximum RAM (4gb) and I wish to add more. It is an ASUS board, AMD X64 dual core, nvidia nic. What I want going to move to is a dell board, Intel Pentium M dual code, which supports 8gb of RAM. Can I just unplug the HD and move it to the new server and boot it up? I assume that the NIC will need to be re-setup, but what other issues would there be? I am not running X at all. Doing apache, zimbra, mysql. Best, -Jason

Rsync over ssh doesn’t works but a little cumbersome – customer’s servers’ data center are far away from development site and link between is slow. So better one to data center’s one and from the latter to all others in data center. This will work better but still could be improved. Since customer has some scripts to be reloaded after codes/data are synced. >You'd probably really want to wrap this with a version control system like subversion to get history, logging, rollback capability, etc. so Is there already an existing solution like this available, open source and commercial? Thanks. --Robinson

UnRAID
by Slack-Moehrle 01 Mar '10

01 Mar '10

has anyone heard of UnRaid at: http://lime-technology.com/ Seems interesting, runs from USB. What I like is that you can add drives to your array without having to destroy it. And it lets you add any size drive that you want. You can mix, say 1tb and 2tb drives. What other ways can I do this without UnRAID? Its limitation is that you cant do anything else and I would want to run other things like apache, mysql, etc. -Jason

Inquery: popular upload tools for customer codes in use
by Robinson Tiemuqinke 01 Mar '10

01 Mar '10

Hi all, I've had a project to upload customer codes and some data to members inside a webfarm, the upload work will be done almost daily for quite a while. Customer needs the upload status be confirmed everytime and data will be verified later easily when in need. Is there one or more popular tools available for this purposes? open source is preferred, but commercial ones are fine too as long as price is aceeptable. Thanks. --Robinson
