Recovering from a failed boot disk is not a very difficult procedure using Solstice DiskSuite when the system has been properly setup and documented initially. Recovering from failures of this nature are good examples of the power of DiskSuite, even in a simple two disk mirroring situation. For the purposes of this demonstration, [...]
In this example we will be mirroring two disks, both on the same controller. The first disk will be the primary disk and the second will be the mirror. The disks are:
Disk 1: c0t0d0
Disk 2: c0t1d0
The partitions on the disks are presented below. There are a few [...]
# cd /home enter to directory ‘/ home’
# cd .. go back one level
# cd ../.. go back two levels
# cd go to home directory
# cd ~user1 go to home directory
# cd – go to previous directory
# cp [...]
# find / -name file1 search file and directory into root filesystem from ‘/’
# find / -user user1 search files and directories belonging to ‘user1′
# find /home/user1 -name \*.bin search files with [...]
# bunzip2 file1.bz2 decompress a file called ‘file1.bz2′
# bzip2 file1 compress a file called ‘file1′
# gunzip file1.gz decompress a file called ‘file1.gz’
# gzip file1 [...]
# find /var/log -name ‘*.log’ | tar cv –files-from=- | bzip2 > log.tar.bz2 find all files with ‘.log’ extention and make an bzip archive
# find /home/user1 -name ‘*.txt’ | xargs cp -av –target-directory=/home/backup/ –parents find and copy all files with ‘.txt’ extention from a directory [...]
The Advanced Packaging Tool or APT, is a free user interface that works with core libraries to handle the installation and removal of software on the Debian GNU/Linux distribution and its variants. APT simplifies the process of managing software on Unix-like computer systems by automating the retrieval, configuration and installation of software packages, [...]
Requirements
Get 2 network interface cards in your machine . It is not required that they be the same type but it is important that they have the same speed capability.
Obtain 4 IP addresses in the same local lan (or vlan) segment. In Multipathing there are 2 fixed (or private) [...]
According to Wikipedia, aggregating network interfaces; a.k.a. link aggregation “is a computer networking term which describes using multiple network cables/ports in parallel to increase the link speed beyond the limits of any one single cable or port, and to increase the redundancy for higher availability.”
This article describes how to aggregate [...]
Most Linux distributions ship with buffers and other Transmission Control Protocol (TCP) parameters conservatively defined. You should change these parameters to allocate more memory to enhancing network performance. Kernel parameters are set through the proc interface by reading and writing to values in /proc. Fortunately, the sysctl program manages these in a somewhat [...]
