NOTE: this post has been replaced by a newer version. Please meet x8dtu, a server destined to be the future home of FreshPorts. There is nothing installed here. In short: FreeBSD 11 booting off a mirrored pair of zfsroot SSDs 4.5TB of mirrored ZFS 196612 MB of RAM (yeah, that’s 196GB of RAM) Supermicro X8TDU motherboard Intel Xeon E5620 @ 2.40GHz (two of those, giving 16 CPUs)
The knew server is ‘frozen’ again. This has been happening daily at about O301 UTC each night. See my Twitter feed for background. In this post I will include details as I progress through the data. The server in question is knew (yes, that’s the hostname). dtrace hotkernel I left this running in an ssh session and pressed control-C this morning: [root@knew:/usr/share/dtrace/toolkit] # ./hotkernel >> /var/tmp/hotkernel ^C ssh login loop It was suggested

Three weeks ago, I thought I had flashed my new LSI SAS 9201-16i. I had not. When I powered up the system via mfsBSD, I could see the device, but during the boot process, there was no splash screen. I now believe this should always be a signal that you have not correctly flashed the card. Finally, I went back to basics. I went back to something I did in photos. I used

I have used ssh-agent for a long time. I enter my passphrase once, then let ssh-agent handle my ssh sessions. Last night, I noticed I ssh’d to a box and did not enter my passphrase. I got logged in. I had just rebooted my laptop so I was very concerned about this. It look at while, but eventually, I discovered the cause. OSX was caching the passphrase. More interestingly, it was not using

This post has been replaced by a newer one. For reference, the previous post on this server is still available. . This server recently moved to a rack-mount chassis. On an interim basis, it contains an LSI SAS 9101-16i. For future reference, this is the slocum server, which I use for various jails and services. The filesystems, well, some of them: And dmesg:
WARNING: This did not work. It succeeded, without error, but the card did not work. There will be a new blog post soon. Yesterday, a new LSI SAS 9201-16i arrived. I bought it on eBay from a supplier in China and paid for expedited shipping. I offered US$250 for their $338 listing and it was accepted. Shipping was another $30. It arrived 6 days later. Why do I need one? The system in

I’m writing this to document the facts. I’ll leave adjectives and opinions to you. Greg Truskey, TruCo was hired to perform renovations which started in August 2015. The estimate was 11 weeks. He was on site from about 9am to 3:30pm. Arriving earlier or late was uncommon. On days he would not arrive, we would not be notified. It would be fine weather, and he would not be present. You will recall the

I noticed this on one FreeBSD server today: $ pkg -vv | grep url url: “pkg+http://services.unixathome.org/packages/103amd64-default-master-list/”, I decided: let’s use https, not http, there. After making the change (in my case, it was in /usr/local/etc/pkg/repos/local.conf, I tried upgraded packages, and it barfed: $ sudo pkg upgrade Updating local repository catalogue… Certificate verification failed for /C=IL/O=StartCom Ltd./OU=StartCom Certification Authority/CN=StartCom Class 2 IV Server CA 34401225432:error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed:/usr/src/secure/lib/libssl/../../../crypto/openssl/ssl/s3_clnt.c:1191: Certificate verification failed for /C=IL/O=StartCom Ltd./OU=StartCom
My first day back from EuroBSDCon 2016, I wanted to fix an issue which arose before the conference. My Cisco AnyConnect client configuration contained old hosts which I no longer used, but didn’t contain the host I was primarily using now. I could add the host, but upon restart, that new host was no longer there. Plus, when started, AnyConnect would attempt to connect to the old host, which is not even remotely
