- Linux: Should You Use Twice the Amount of Ram as Swap Space?
Linux and other Unix-like operating systems use the term “swap” to describe both the act of moving memory pages between RAM and disk, and the region of a disk the pages are stored on. It is common to use a whole partition of a hard disk for swapping. However, with the 2.6 Linux kernel, swap files are just as fast as swap partitions. Now, many admins (both Windows and Linux/UNIX) follow an old rule of thumb that your swap partition should be twice the size of your main system RAM. Let us say I’ve 32GB RAM, should I set swap space to 64 GB? Is 64 GB of swap space really required? How big should your Linux / UNIX swap space be?
- Linux tgtadm: Setup iSCSI Target ( SAN )
Linux target framework (tgt) aims to simplify various SCSI target driver (iSCSI, Fibre Channel, SRP, etc) creation and maintenance. The key goals are the clean integration into the scsi-mid layer and implementing a great portion of tgt in user space.
The developer of IET is also helping to develop Linux SCSI target framework (stgt) which looks like it might lead to an iSCSI target implementation with an upstream kernel component. iSCSI Target can be useful:
a] To setup stateless server / client (used in diskless setups).
b] Share disks and tape drives with remote client over LAN, Wan or the Internet.
c] Setup SAN - Storage array.
d] To setup loadbalanced webcluser using cluster aware Linux file system etc.In this tutorial you will learn how to have a fully functional Linux iSCSI SAN using tgt framework.

- What To Do: Users Still Wants Telnet
TELNET (TELecommunication NETwork) is a network protocol used on the Internet or local area network (LAN) connections. It was developed in late 60s with RFC 15. Telnet is pretty old for login into remote system and it has serious security problem. Most admins will recommend using Open SSH (secure shell) for all remote activities. But you may find users who are still demanding telnet over ssh as they are comfortable with Telnet. Some users got scripts written in 90s and they don’t want to change it. So what do you do when users demands telnet?
- Critical Red hat / Fedora Linux Openssh Security Update
Last week one or more of Red Hat’s servers got cracked. Now, it has been revealed that both Fedora and Red Hat servers have been compromised. As a result Fedora is changing their package signing key. The intruder was able to sign a small number of OpenSSH packages relating only to Red Hat Enterprise Linux 4 (i386 and x86_64 architectures only) and Red Hat Enterprise Linux 5 (x86_64 architecture only). This update has been rated as having critical security impact.

- dnsmasq Dns Cache Software Security Update To Fix DNS Spoofing Attacks
Red Hat has shipped a new version of its dnsmasq caching software to plug source UDP port bug. This could have made DNS spoofing attacks (CVE-2008-1447) easier. Dnsmasq is lightweight ultra fast dns cache server forwarder and DHCP server. It is designed to provide DNS and, optionally, DHCP, to a small network.
