Bryan Cantrill in BSD Now podcast
The lastest episode of BSD Now (103) podcast brought in a fantastic and hilarious interview with Bryan Cantrill who is well known for his wit and right on the bullseye rants. It’s been awhile since I cried laughing so unquestionably this video is a highly recommended. Not to mention that his talk was very educational […]
In: FreeBSD, Solaris, Sun
AWS FreeBSD instance won’t come up. Screams for manual fsck.
This is a short write up if after a reset or a reboot your FreeBSD (or Linux) instance doesn’t come online, stalls and “aws ec2 get-console-output” returns something like that among its lines: UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY. Just power-off the faulty instance either from Web interface or using cli: aws ec2 stop-instances –instance your_instance_id […]
How to power off USP-V when it doesn’t want to
In the era of VSP G1000 this post may sound dated but I still hope that it would help some poor sole in the same situation I was sometime ago. The task was laughably simple: power off USP-V, power it up just to make sure it still could boot up flawlessly and shut it down […]
Configuring FCoE in Linux (RHEL) and HP FlexFabric
Actually it’s easy. Very easy indeed, like going 1, 2, 3. Collect information about MAC addresses to distinguish pure Ethernet NICs and CNA that will pass FCoE traffic. The latter have both MAC and WWN addresses. Power on a server and update /etc/udev/rules.d/70-persistent-net.rules if required. Activate new dev rules: Install fcoe-utils and lldpad packages: Rename […]
Solaris checkinstall script did not complete successfully
This is another post about the usefulness of reading man pages and READMEs. The other day I was patching a Solaris box and was greeted with the following error: This appears to be an attempt to install the same architecture and version of a package which is already installed. This installation will attempt to overwrite […]
OpenSSL TLS 1.1 and wrong version number
If you, like myself, have been living under a rock you’d be also surprised to know that OpenSSL didn’t support TLSv1.1 and TLSv1.2 until version 1.0.1 . Found out that accidently by trying to disable TLSv1 in Nginx which was running on a RHEL5 box with OpenSSL 0.9.8e. Below is how TLS handshake looked when […]
Linux pptp stumbling blocks that I was hit by
While configuring a pptp on a Linux box I bumped into the several smalish issues which I’d like to blog about. Make sure that your network engineers have enabled traffic inspection on all intermediate firewalls between tunnel’s endpoints. Otherwise LCP won’t be able to finish its configuration negotiation phase even if the control channel on […]
Don’t forget to apply Solaris Live Upgrade patch or …
One day you might find yourself in a similar situation as I did when I wasn’t able to create a new boot environment: # lucreate -n SolarisFeb16 Analyzing system configuration. Comparing source boot environment file systems with the file system(s) you specified for the new boot environment. Determining which file systems should be in the […]
Videos from EuroBSDCon 2014
In the last episode of BSDNow podcast a link to the videos from EuroBSDCon 2014 has been published – https://va.ludost.net/files/eurobsdcon/2014/Vitosha/ The one I enjoyed most was a presentation made by Kirk McKusik about the implementation of ZFS. Worth watching indeed.
Redmine Time logging via commit checklist
Redmine has a very handy feature, called Time tracking feature, that allows you to log the time your spent working on a code via a commit message. However, it didn’t fly out-of-the-box in my case. If you find yourself in a similar situation you could take a look at the checklist below to verify that […]
