Surf Safely with sshuttle
In past articles, I've explained how to set up a SOCKS proxy with SSH. I've demonstrated how to tunnel traffic with SSH. I've even shown how to circumvent a company firewall with SSH. I've never been able to use SSH completely as a VPN, however, and that's always bummed me out—until I discovered sshuttle.
Mind you, sshuttle isn't a new program. It isn't even a new concept. What it is, however, is pure awesome. Basically, launching the sshuttle binary with root privileges will modify your system firewall to tunnel all (yes all) traffic through a remote SSH connection. The remote connection doesn't even need administrator privileges, so your shell account at your Web host might suffice for securing your traffic in a hotel or coffee shop. sshuttle will even tunnel your DNS lookups, which means your entire network interaction should be secure and encrypted.
sshuttle is in many OS repositories, or you can downloaded it from https://github.com/apenwarr/sshuttle.
With a simple
sudo sshuttle --dns -vvr username@server 0/0, all your traffic will be encrypted and funneled through the remote server. Because DNS also is tunneled, it means you won't be vulnerable to DNS poisoning either! Check out sshuttle today. You won't be sorry.
Practical Task Scheduling Deployment
One of the best things about the UNIX environment (aside from being stable and efficient) is the vast array of software tools available to help you do your job. Traditionally, a UNIX tool does only one thing, but does that one thing very well. For example, grep is very easy to use and can search vast amounts of data quickly. The find tool can find a particular file or files based on all kinds of criteria. It's pretty easy to string these tools together to build even more powerful tools, such as a tool that finds all of the .log files in the /home directory and searches each one for a particular entry. This erector-set mentality allows UNIX system administrators to seem to always have the right tool for the job.
Cron traditionally has been considered another such a tool for job scheduling, but is it enough? This webinar considers that very question. The first part builds on a previous Geek Guide, Beyond Cron, and briefly describes how to know when it might be time to consider upgrading your job scheduling infrastructure. The second part presents an actual planning and implementation framework.
