Today's system administrators deal with a vast number of situations, operating systems, software packages, and problems. Those who are in the know have kept their copy of Linux Server Hacks close at hand to ease their burden. And while this helps, it's not enough: any sys admin knows there are many more hacks, cool tips, and ways of solving problems than can fit in a single volume (one that mere mortals can lift, that is).

Which is why we created Linux Server Hacks, Volume Two, a second collection of incredibly useful tips and tricks for finding and using dozens of open source tools you can apply to solve your sys admin problems. The power and flexibility of Linux and Open Source means that there is an astounding amount of great software out there waiting to be applied to your sys admin problems -- if only you knew about it and had enough information to get started. Hence, Linux Server Hacks, Volume Two.

This handy reference offers 100 completely new server management tips and techniques designed to improve your productivity and sharpen your administrative skills. Each hack represents a clever way to accomplish a specific task, saving you countless hours of searching for the right answer. No more sifting through man pages, HOWTO websites, or source code comments -- the only resource you need is right here. And you don't have to be a system administrator with hundreds of boxen to get something useful from this book as many of the hacks apply equally well to a single system or a home network.

Compiled by experts, these hacks not only give you the step-by-step instructions necessary to implement the software, but they also provide the context to truly enable you to learn the technology. Topics include:
* Authentication
* Remote GUI connectivity
* Storage management
* File sharing and synchronizing resources
* Security/lockdown instruction
* Log files and monitoring
* Troubleshooting
* System rescue, recovery, and repair

Whether they help you recover lost data, collect information from distributed clients, or synchronize administrative environments, the solutions found in Linux Server Hacks, Volume Two will simplify your life as a system administrator.

gives me 600 GB of reliable, mirrored storage to provide to users. If you're less nervous than I am, you can skip the RAID step and just use LVM to deliver all 1.2 TB to your users, but backing that up will be a nightmare, and if any of the drives ever fail, you'll have 1.2 TB worth of angry, unproductive users. If you need 1.2 TB of storage, I'd strongly suggest that you spend the extra $1000 to build a second one of the boxes described in this hack. Mirroring is your friend, and it doesn't get

a machine outside your network and issue the nmap command, identifying the machine on which you're running snort as the target, as in the following example: $ nmap -P0 24.3.53.235 Starting nmap V. 2.54BETA31 ( www.insecure.org/nmap/ ) Warning: You are not root -- using TCP pingscan rather than ICMP Nmap run completed -- 1 IP address (0 hosts up) scanned in 60 seconds You can now check /var/log/snort, in which you should see a filenames alert with contents like the following: a[**]

add some hosts to it. Select the host we created in the previous example, Home-FTP. You can then select the coordinates you wish for the icon representing Home-FTP to be displayed on. Select the Server icon and click Add. The page will refresh, and when it finishes loading, you'll see your icon representing Home-FTP on the map. You can continue adding hosts and placing them on the map until you have a full representation of your network. The Details What we've covered here is a fraction

starting point, and work from there. Far more detail can be found online and in the manpages. On your central log server, add the following to /etc/syslog-ng/syslog-ng.conf: options { long_hostnames(off); sync(0); keep_hostname(yes); chain_hostnames(no); }; source src {unix-stream("/dev/log"); pipe("/proc/kmsg"); internal();}; source stunnel {tcp(ip("127.0.0.1") port(514) max-connections(1));}; destination remoteclient {file("/var/log/remoteclient");}; destination dest

centralized servers to satisfy the requirements of many clients isn't just a buzzword; it's an efficient use of your time and system resources, and it simplifies administering those services in the future. This chapter provides hacks that discuss setting up centralized services for allocating IP addresses to new clients via the Dynamic Host Configuration Protocol (DHCP), integrating these newly assigned IP addresses with an existing Domain Name Service (DNS), synchronizing the clocks on all of
