While the Solaris has the updated netstat with -u flag, illumos requires certain improvements in sockinfo, and possibly, rpcbind (tcpConnCreationProcess shows the old PID for rpcbind, until it did not become a demon). With help of pfiles is possible to obtain the desired information about pid for particular port, so I wrote a small pfiles-based utility which allows to determine the PID, user and command for the particular port:
Fifteen years ago, I initiated a time-honored tradition among my colleagues in kernel development at Sun: shortly after the first of every year, we would get together at our favorite local restaurant to form predictions for the coming year. We made one-year, three-year and six-year predictions for both our technologies and more broadly for the industry. We did this for nine years running — from 2000 to 2008 inclusive — and came to know the annual ritual as a play on the restaurant name: Predicteria.
When looking back on 2014 from an infrastructure perspective, it’s hard not to have one word on the lips: Docker. (Or, as we are wont to do in Silicon Valley when a technology is particularly hot, have the same word on the lips three times over à la Gabbo: “Docker, Docker, DOCKER!”) While Docker has existed since 2013, 2014 was indisputably the year in which it transcended from an interesting project to a transformative technology — a shift which had profound ramifications for us at Joyent.
We built DTrace to solve problems; at the start, the problems we understood best were our own. In the Solaris Kernel Group we started by instrumenting the kernel and system calls, the user/kernel boundary. Early use required detailed knowledge of kernel internals. As DTrace use grew—within the team, in Sun and then beyond—we extended DTrace to turn every function and every instruction in user programs into probes. We added stable points of instrumentation both in the kernel and in user-land so that no deep knowledge of program or kernel internals would be required.
In the frenzied, insular world of a Silicon Valley startup it can be easy to lose perspective on the broader community in which we live and work. Among the great hackathon projects to come from our bi-annual engineering event was the idea of “Angel Sharks”, a group of volunteers at Delphix who provide opportunities for volunteering and community giving.

A quick blog entry about getting Solaris PXE boot working with Microsoft Windows DHCP server. I was always told it was easy but I never managed to get it to working even though a lot of people I talked to had it working.
Today we are announcing that we are open sourcing the two systems at the heart of our business: SmartDataCenter and the Manta object storage platform. SmartDataCenter is the container-based orchestration software that runs the Joyent public cloud; we have used it for the better half of a decade to run on-the-metal OS containers — securely and at scale.
