Support For Shared Named Semaphores
Contributed by jcr on Thu Nov 28 02:50:36 2013 (GMT)
from the lord-voldebert-is-out-to-lunch dept.

OpenBSD developer Ted Unangst (tedu@) recently wrote a blog post on Shared Named Semaphores and with permission it's reposted below:

Support for shared named semaphores, ala sem_open(3), recently arrived in OpenBSD. OpenBSD already supported single process thread shared semaphores, ala sem_init(3), and the old school SysV semaphores, ala semget(2). There are still a few tweaks being made, but the internal design hasn't changed in 24 hours so I figure it's safe to discuss the implementation.

The 2013 Chuck Yerkes Award Goes To...
Contributed by jcr on Thu Nov 28 02:48:08 2013 (GMT)
from the contributions-remembered dept.

For those who have joined OpenBSD during the last decade, you've missed out on someone special, Chuck Yerkes. Chuck contributed a lot to sendmail(8) and the various OpenBSD mailing lists. He was always willing to help others and took the time to provide useful and accurate advice. Chuck also had a vivid sense of humor ("Shirt, Shoes, Sober... --Pick Two").

LOPSA (League Of Professional System Administrators) recently announced the winner of the 2013 Chuck Yerkes Award:

For those of you who never got to know him, Chuck Yerkes was known for always being willing to help and mentor others both in person and on sysadmin mailing lists in the 1990's and early 2000's. Countless sysadmins over the years have learned from his postings. Chuck's intelligence, knowledge, and dedication to doing things right is something that is missing all too frequently in the on-line community. Unfortunately Chuck passed away in late 2004 after being involved in an accident on his way home from work.

In 2005 an award was created in his memory to annually honor a sysadmin who most embodies Chuck's spirit in assisting and mentoring other sysadmins. Each year the LOPSA awards committee sifts through sysadmin blogs, the LOPSA IRC channels, mailing lists, web forums and other sysadmin on-line resources in search of someone who is leading in contributions to the sysadmin community as Chuck did.

BSDNow Episode 012: Collecting SSHells - A guide to SSH and tmux
Contributed by jcr on Tue Nov 26 06:35:48 2013 (GMT)
from the just-muxing-around dept.

In "Episode 012: Collecting SSHells" the media magicians of BSDNow bring us the BSD news of the week along with their weekly tutorial, "A guide to SSH and tmux". OpenBSD is the reference and development platform for both OpenSSH and tmux, so all of the newest features show up here first. Since they're both written to be portable and have an unrestrictive, freely reusable license, everyone can use them and many operating systems and/or distributions include them.

Managing Individual IPsec Tunnels On A Multi-Tunnel Gateway
Contributed by jcr on Mon Nov 25 04:14:12 2013 (GMT)
from the easier-to-create-than-to-destroy dept.

Philipp Buehler ("double-p" or formerly pb@) wrote in to tell us about how he handles the problem of tearing down a stalled ipsec(4) connection when running tons of busy and important tunnels.

Since the early days of ipsec.conf(5) it's rather easy to add IPsec connections throughout the networks, so ipsec.conf(5) keeps getting longer and longer. The isakmpd(8) daemon is playing nice with it's (new) peers and the sun is shining - until it isn't. Think of five, ten or 25 tunnels humming critical traffic, and this new peer is just not accepting proposals or doing wrong in so many other ways. One ends up with half-up Phase 1 or Phase 2 connections, where either peer is trying hard to get its proposals through and one can only watch it.

Restart the whole thing? Eventually it will end with a working configuration for weirdo-peer, but it also gains angry customers losing their tunnels until it was figured out. Additionally, the mighty defaults of lifetimes will likely end in CPU spiking while calculating new keys all at the same time.

What to do about it? Obviously, it's per-tunnel configuration and especially bring-up and tear-down of individual working or not-so-working tunnels.

from the some-play-football-with-their-hands dept.

OpenBSD developer Brian Callahan (bcallah@) wrote in to say:

The date of NYCBSDCon 2014 has been pushed back one week to Feb 8, 2014. This was due to flights and hotels being simply too expensive (the Super Bowl is being held in NY/NJ on Feb 2).

In case you missed it, earlier this week undeadly posted the announcement for the NYCBSDCon 2014 Call For Papers And ExposÚs
