Fluke Networks recently released TruView Live, a subscription-based service for monitoring internal & external applications. Tests can run from Fluke-managed cloud locations, your own systems, or from dedicated hardware appliances. I’ve been testing it out, and I like it so far.
(Read more...)Here’s a couple of quick hacks for working with Brocade Network Advisor. It’s unsupported, but you can run BNA on Ubuntu. You can also suppress the client-side JRE version mismatch warning.
(Read more...)I made a conscious decision to move away from full-time information security work. I retain an interest, and try to keep up with developments, but I don’t want to be “the security guy.” There are several reasons for it, but a large part is due to the hype, the bullshit, and general inability for the security industry to act like grown-ups.
(Read more...)I have been investigating a problem where an application would install on RHEL/CentOS, but not on Ubuntu. I tracked it down to a problem with shell scripts that assumed that /bin/sh was bash. Ubuntu uses dash by default, so some ‘bashisms’ don’t work. This will be old news to Ubuntu types that migrated to dash a while back, but I normally use CentOS/RHEL systems, and/or well-behaved cross-platform scripts. Luckily ‘checkbashisms’ can help with figuring out what changes are needed.
HP IMC 7.1 E0303P13 does not support configuration backups for Brocade MLX & VDX devices. But they do have an extensible model, so it’s easy to add support. Here’s how to do it, and how to fix the Brocade ICX support.
(Read more...)ipv6-test.com is a useful site for testing IPv4 & IPv6 connectivity. It checks that v4 & v6 are working as expected, and reports your browser v4/v6 preferences. It does have one oddity with ICMPv6 tests. Here’s what I did to work around it with my SRX setup.
(Read more...)It’s 2015. ARIN is finally out of IPv4 addresses, more than 20% of Google users in the US are using IPv6…and vendors are still doing a half-assed job with IPv6 support. I purchased a new TP-Link Wi-Fi router/modem recently, and it doesn’t fully support IPv6. It’s not good enough, and I will be returning it.
(Read more...)Can we broadly separate Networking into Pioneers, Settlers, and Town Planners? I’ve been thinking about how to apply Simon Wardley’s PST model to networking. This leads to thinking about how we can encourage networking evolution. The model needs a lot of fleshing out, but I’m interested in what others think.
(Read more...)Let’s say you’ve been offered a new job. $70k base salary, with up to $20k per year extra for on-call duties. Great! $90k! That’s $10k more than my salary now! Sign me up!
(Read more...)If you’ve visited the Brocade website recently, you’ve probably seen the “Free NFV Certification” banner. I signed up for this several months ago, but had put off completing the course. I had a little downtime recently prior to starting work at Brocade, so I completed this course & exam. Here’s my impressions.
