After you have successfully configured at least one master NIS server, you are ready to configure one or more NIS clients. FreeNAS has helped build our virtualization platform to this effect and has provided us with a very flexible system through with a ROI not matched by any competitor on either the Open-Source or Closed-Source market.” “I’m a big, big fan of the platform. Clicking on the SMB tab opens the SMB configuration screen, where you can enable SMB and choose the following options: N SMB server — Shows the name of the SMB server you will use N SMB workgroup — Shows the name of the workgroup containing the 51 SMB server or servers After you have finished setting your configuration options on the Authentication Configuration screen, click the Next button to proceed to the next configuration step.

For additional information, see the GNU texinfo pages for the shell-utils package (info shell) Host Your Web Site In The Cloud: Amazon Web Services Made Easy: Amazon EC2 Made Easy When you use LVMs, you need a new way of thinking about disk space. First you have to understand that space on any disk can be used by any file system. A Volume Group is the term used to describe various disk spaces (either whole disks or parts of disks) that have been grouped together into one volume , cited: Advanced Guide to Linux read for free The tasks involved in this phase are a major responsibility for network administrators. You should expect to perform these tasks unless your organization is very large, with an adequate network structure already in place Pro Oracle Database 11g RAC on Linux (Expert's Voice in Oracle) Configure TCP/IP (and IPv6 ) for Unix/Linux workstations and servers: set NIC to use DHCP and over-ride DHCP server assigned settings, assign static IP to a NIC; use ifconfig; understand and configure IP Alias (virtual interfaces) Configure routing for Unix/Linux workstations and servers; use the route command; configuring a default route; identification of common routing daemons: ripd, zebra, gated, quagga, xorp, in.routed (Solaris), routed (Free BSD, which also supports gated and zebra); configure zeroconf networking Configure network access controls using TCP Wrappers (libwrap), by using /etc/host.allow and host.deny files; set a mostly-closed policy; identify other ways to implement service access controls including service specific configuration, xinetd, PAM, and firewall rules Troubleshoot TCP / IP network problems using log files, a trouble-shooting methodology, and some common tools including ping, traceroute, telnet, nc (netcat), openssl, netstat, route, ifconfig, Wireshark, tcpdump, and others ref.: LINUX Netwosrk Administration read here read here.

Currently it includes information about script writing in Linux, with information about Linux structures and signals required for programming. This document will be expanded to include C++, and GUI tools as time permits. The documentation written by Mark Allen was written as Linux was learned ref.: Linux System Administration by download for free If you have an ADSL connection and use an ADSL router, this looks to Linux just like a normal Ethernet connection. As such, you need neither specific hardware (except an Ethernet card, of course) nor special drivers besides the Ethernet card driver itself. If you want to connect your Linux box directly to your ADSL modem, you still don't need to have any particular hardware or driver, but you do need to run a protocol called PPPoE (PPP over Ethernet); more about this later ref.: Linux Mint System read for free read for free. Projects such as Fink, MacPorts and pkgsrc provide pre-compiled or pre-formatted packages. Since version 10.3, Mac OS X has included, Apple’s version of the X Window System graphical interface for Unix applications, as an optional component during installation.

Forwarding allows the network packets on one network interface (i.e. eth0) to be forwarded to another network interface (i.e. eth1). This will allow the Linux computer to connect ("ethernet bridge") or route network traffic. The bridge configuration will merge two (or several) networks into one single network topology LINUX Network Administrator's download online You must have the file system support and the file partitioning support turned on in the kernel. Usually file system support is compiled as a module by default, but disk partition support usually has to be explicitly compiled. Some common partitioning schemes that Linux supports are: x86 partitions, BSD disklabel, Solaris x86, Unixware, Alpha, OSF, SGI, and Sun. Mounting other operating systems’ partitions is helpful if you need to put a Sun hard disk into a Linux machine, for example , e.g. RHCSA/RHCE Red Hat Linux Certification Practice Exams with Virtual Machines, Second Edition (Exams EX200 & EX300) download for free. The simplest entry takes the form: This entry tells clients to use the server whose IP address is nisserverip. An example of this kind of entry might be: A somewhat more flexible approach enables clients to broadcast a query for the server to contact for a given NIS domain. This method saves tedious editing of client configuration files if (or, perhaps, when) the IP address of the NIS server changes Linux study guide: Linux study read epub read epub. This is the basic structure upon which the Internet is based: a seemingly infinite chain of networks, interconnected via gateways Guide to Linux Networking and Security by Nick Wells (2002-10-14) When user exits from the editor, the modified crontab will be installed automatically. Each user can have their own crontab, and though these are files in /var, they are not intended to be edited directly. If the –u option is given than the crontab gives the name of the user whose crontab is to be tweaked. If it is given without this then it will display the crontab of the user who is executing the command online.

The default value is yes, as the atalk script normally runs on boot and it is customary to launch daemons in the background. The only reason to change this option to no is if you are going to run atalk manually from the command line.
