I am installing Red Hat Linux 6.0 on a partition. When I try to make my partitions for Linux, it gives me an error saying “boot partition too big”. I tried to use fdisk and it says my hard drive has 1655 cylinders, not 1024, and it will cause problems. How can I get around this? —Will Brown, email@example.com
Create a primary partition (the first one) with 10MB; its mount point should be /boot. This is the directory where all the boot images reside, and it needs to be under the 1024 cylinder. The root partition (/) can then be any size, and will not have any problems. —Paulo Wollny, firstname.lastname@example.org
Most PC bioses are still unable to access data beyond the 1024th cylinder. This prevents LILO from booting a kernel that's lying beyond the 1024th cylinder. To get around this, short of getting an alternate architecture without all those ancestral PC limitations, you need to have your boot partition (either /boot if you have one, or your root partition otherwise) completely under the 1024th cylinder. —Marc Merlin, email@example.com
I am setting up a small LAN at home with a server running Red Hat 6.1 and a workstation running Windows 98. I've set each up with a static IP address (192.168.1.1-2) and a netmask of 255.255.255.0. My problem is that I can't even ping my Linux box using the host name. I can ping it using the IP address, and I can ping my Windows 98 box from the Linux box using either the host name or the IP address. I'd appreciate any suggestions you may have.
I had an older version of Linux (Red Hat 5.3, I believe) on the server, and it was working perfectly. I've set up the 6.1 version the same way and it won't work. —Greg Wright, firstname.lastname@example.org
You didn't mention whether you've configured DNS services at home, so I'll assume you have not. In that case, you need to add an entry to your c:\windows\hosts file. List the IP address of the system you are trying to ping, followed by the host name you wish to use in your ping test. Be sure you do not include the domain name in this entry. You can copy the file hosts.sam if you need a sample. —Chad Robinson, Chad.Robinson@brt.com
I am using SuSE 6.3 and had two networks, one at the main office (192.168.1.0) and the other at the branch (192.168.2.0). I used two Cisco 800 routers to connect them. I can use TCP/IP normally (ping, ftp, http from one host to another). My problem is I cannot see the remote PCs in Windows Explorer at the office. I configured a Linux server with DNS, mail and FTP, but it still doesn't work. At the office, I'm running IPX (there is a Netware 3.11 server) and TCP/IP protocols. Someone told me I must set up a Windows NT running WINS service. I don't want to install Windows NT. Any ideas? —Carlos Germán Siufi, email@example.com
This question involves Windows networking, and more specifically, netbios name lookup. Netbios, which is at the core of Windows networking, was very badly designed and grew from there. While UNIX uses DNS for name lookup, Windows originally used a complicated name lookup scheme based on the election of a local name browser on your subnet and broadcast queries for each name lookup. Because it is broadcast-based, it doesn't work across subnets (which is your configuration), and it was “improved” with the addition of WINS.
The typical solution is indeed to use a WINS server, which is some kind of dynamic DNS equivalent, although it isn't as robust. However, you do not need to run Windows to provide WINS service; Samba (http://www.samba.org/) can do this just fine. While using a WINS server would typically require you to configure each Windows machine, Samba can function as a proxy between local broadcast queries and a remote WINS server. You ought to grab Samba and read its documentation for more info. You may also want to consider getting one of the Samba books. —Marc Merlin, firstname.lastname@example.org
I need to know how to set my display mode when I start the X Window System. It always runs X at 320x300 or something really huge and I can't do anything. I use—Jim, email@example.com
Red Hat's X configuration tool is called Xconfigurator. If it doesn't work for you, then you should first check that your graphics card is supported by your version of XFree86 at http://www.xfree86.org/#resources/. It may be that your video card is supported by a later version of X, in which case you should upgrade. If your video card is recent, it is most likely Vesa 2-compatible, and you can use the VesaFB server: http://www.xfree86.org/FAQ/#FBDev/. —Marc Merlin, firstname.lastname@example.org
Practical Task Scheduling Deployment
July 20, 2016 12:00 pm CDT
One of the best things about the UNIX environment (aside from being stable and efficient) is the vast array of software tools available to help you do your job. Traditionally, a UNIX tool does only one thing, but does that one thing very well. For example, grep is very easy to use and can search vast amounts of data quickly. The find tool can find a particular file or files based on all kinds of criteria. It's pretty easy to string these tools together to build even more powerful tools, such as a tool that finds all of the .log files in the /home directory and searches each one for a particular entry. This erector-set mentality allows UNIX system administrators to seem to always have the right tool for the job.
Cron traditionally has been considered another such a tool for job scheduling, but is it enough? This webinar considers that very question. The first part builds on a previous Geek Guide, Beyond Cron, and briefly describes how to know when it might be time to consider upgrading your job scheduling infrastructure. The second part presents an actual planning and implementation framework.

With all the industry talk about the benefits of Linux on Power and all the performance advantages offered by its open architecture, you may be considering a move in that direction. If you are thinking about analytics, big data and cloud computing, you would be right to evaluate Power. The idea of using commodity x86 hardware and replacing it every three years is an outdated cost model. It doesn’t consider the total cost of ownership, and it doesn’t consider the advantage of real processing power, high-availability and multithreading like a demon.
This ebook takes a look at some of the practical applications of the Linux on Power platform and ways you might bring all the performance power of this open architecture to bear for your organization. There are no smoke and mirrors here—just hard, cold, empirical evidence provided by independent sources. I also consider some innovative ways Linux on Power will be used in the future.Get the Guide
