Stefan Lasiewski

Daddy, Linux Guy, Bicyclist, Tinkerer, Fixer & Breaker of things.

I work as a Senior Server Team Engineer at the National Energy Research Scientific Computing Center (NERSC) Division at Lawrence Berkeley National Laboratory (LBNL) in Berkeley, CA.

Father of 3 cute children. Yes I'm a sysadmin and a parent.

Heavy user of CentOS, RHEL & FreeBSD for production services at work. I also run Ubuntu at home, for the simplicity. I'm a fan of Apache HTTP Server, Nagios & Cacti.

Original proposer of unix.stackexchange.com (Yes, this proposal predated askubuntu.com, and I wish they would have merged with the Unix proposal.).

comment Can OpenSSL be used to debug an SSL connection to a MySQL server?
Hm, I suppose the behavior I'm talking about is how STARTTLS works, according to en.wikipedia.org/wiki/STARTTLS .

Remember -- at some point, you modified your DNS records to use Google. Undo that step.

comment Linux CLI command for ~“what is this machine”?
GNU/Linux doesn't provide a single, unified "standard command" to describe a server. facter is one of the most commonly used alternatives, however.

comment Why is Linux kdump not writing to /var/crash?
No I do not have a watchdog rebooting the machine. Turns out that the LSI controller + Samsung SSDs are periodically freezing for reasons that we don't totally understand.

comment Why doesn't Kosovo have its own ccTLD yet?
A ccTLD isn't always associated with a real-world political entity. The domain for the former Soviet Union still exists as .su. nic.su/dns/domain/su.html

comment How to generate a Self Signed SSL Certificate bound to IP address?
Your browser will still complain due to a lack of trust with any self-signed certificate. "self signed" mean's that the certificate was not signed by any trusted Certificate Authority, and the browser will not trust it by default.
