The version of tar in most Linux distributions supports gzip compression. This means that a gzipped tar file can be extracted in one simple command.
Solaris allows multiple virtual or logical interfaces to exist with different IP addresses on the same physical interface. Virtual interfaces are created or plumbed up using the plumb directive in ifconfig. They are unplumbed using the unplumb directive.
Solaris 8 and 9 have a powerful, integrated mechanism originally available only in trusted environments. Role based access control (RBAC) implements an authorization system based on least privilege. In this model, multiple administrative roles can be created and associated with users such that an individual has only the access necessary to perform their delegated tasks such as restarting privileged services, rebooting the system, or managing the print queue. RBAC allows finer grain control of implementing security policies. This recipe is the first of a series about RBAC and provides an introduction to its components.
AIM is an easy and free way to send SMS text messages.
This tech-recipe describes how to easily redirect a web visitor using meta refresh.
Errors in a filesystem can prevent a system from booting properly and are commonly caused by improper system shutdown. The fsck (filesystem check) utility can identify and repair errors.
When filesystem errors prevent a reboot, you are instructed to run fsck on the affected filesystem. If there are lots of errors, you may be stuck typing y for hours. An option to fsck can automatically answer yes for you.
Solaris can request IP address and other networking information dynamically with DHCP.
When troubleshooting networking issues, it is often helpful to determine the state of an ethernet interface. Solaris offers access to many configurable networking parameters through ndd.
RIP routing is a distance-vector routing protocol which is simple to configure. The routing protocol determines the best path to a target by estimating the distance in number of hops or intermediate routers.
IGRP is a proprietary routing protocol designed by Cisco and can only be used in a homogeneous network of Cisco routers. IGRP is a distance-vector protocol that considers delay, bandwidth and other optional parameters to determine the best path.
Save the router config from the command line.
