GNS3 Version 2 Released!
For the uninitiated, GNS3 is an OpenSource, cross-platform network virtualization software, that’s
“used by hundreds of thousands of network engineers worldwide to emulate, configure, test and troubleshoot virtual and real networks. GNS3 allows you to run a small topology consisting of only a few devices on your laptop, to those that have many devices hosted on multiple servers or even hosted in the cloud.“

Ever since the crowd-funding campaign a couple of years ago, the project has benefited from a surge in development, culminating in the latest release announced today.
By the way, there’s a GNS3 Academy now, bringing a more democratized approach to training through the use of OpenSource software and affordable prices.  Hopefully, this will do for Networking courses and labs what Udemy, edX, and others have done for other technology-related fields.  Unfortunately, the proprietary hardware and software of industry giants like Cisco or VMWare will continue to be barriers to entry for prospective Networking professionals and students.  Nevertheless, the barriers are being either lowered through OpenSource alternatives or circumvented entirely by new technologies and trends; e.g. Software-Defined Networking (SDN) and off-premise (cloud) service providers like Amazon (AWS).

Configure rsyslog Server on Fedora

Image
It can be very beneficial for system administrators and network administrators, especially, to log system messages from other machines on the network to a centralized hub. Fedora 20 uses rsyslog as the default syslogd service; this allows administrators to configure remote logging. I'll be detailing the necessary configuration steps of rsyslog in Fedora 20 to allow logging messages from a DD-WRT router. This will entail Edit /etc/rsyslog.conf Set up firewall rule to allow incoming connection to server Configure DD-WRT router to send syslogd messages to our server rsyslog server Our server will be the Fedora 20 machine. There are two configuration files in the /etc/ directory that are of interest to us: /etc/rsyslog.conf /etc/sysconfig/rsyslog However, the latter file is not useful anymore as it states: # Options for rsyslogd # Syslogd options are deprecated since rsyslog v3. # If you want to use them, switch to compatibility mode 2 by "-c 2" # See rsy

RHEL 7 and CentOS 7 syslog Rate Limit

https://access.redhat.com/solutions/1417483 In RHEL 7 there is rate-limiting both in systemd-journald and in rsyslog's imjournal module Lower Ratelimit Interval Lower the interval for rate-limiting and increase the burst level in order to minimize the possibility of losing log messages when the threshold is reached for the specified number of messages logged within the specified interval. Rate-limiting is specific to each process, so there's usually no reason to change this. It is also inadvisable to disable this feature entirely! grep -i rate /etc/systemd/journald.conf #RateLimitInterval=30s #RateLimitBurst=1000 RateLimitInterval=10s RateLimitBurst=3000 grep -i rate /etc/rsyslog.conf #$imjournalRatelimitInterval 600 <--default $imjournalRatelimitInterval 300 $imjournalRatelimitBurst 30000 journal corruption journalctl --verify journalctl --force

EFF Announces Voting Registration Service

The Electronic Frontier Foundation ( EFF ) has announced a Beta version of their ongoing project to facilitate voter registration for United States elections.  The server allows the user to text the service, HelloVote , in order to register. There is another service provided by VotePlz.org that allows citizens to: Not sure if you’re registered? No problem! We’ll check if you’re registered to vote at your current home address. Don’t have time to vote in person? You can vote by mail instead—it’s even easier! Want to vote in person? We’ll show you where your nearest polling station is and help you get there. Don’t have a stamp or a printer? That’s all right! We can mail you a form, or print a form with pre-paid postage.
