Speaker: leyrer

Leyrer - rants, Linux, command lines, old computer systems, IT fails, bad puns and lot's of sarcasm. If you ask a question at one of my talks, Manner might be in your future.

Leyrer has been working with computers for almost 40 years and has been earning money with them for 30 years. He boldly administers systems that no one else dares to attack - some call it “palliative system administration”.
Alongside or as part of his work as a Senior Lab Services Consultant, he drags sysadmins from the 1990s into the 21st century and has to explain to managers time and again that the cause of the problem is not product XYZ, but (please tick as appropriate): [ ] the cable, [ ] the switch port, [ ] DNS, [ ] yes, it's really the round-robin setup of DNS, [ ] WINS instead of DNS, [ ] disk i/o, [ ] network i/o, [ ] CPU overprovisioning, [ ] the locked system account in AD, [ ] the old ciphers in the TLS configuration, [ ] the missing intermediate certificate,[ ] Layer 8+, [ ] NFS settings, [ ] ACLs, [ ] the UTF-8 BOM, [ ] Microsoft's RFC ignorance, [ ] the WLAN reception through 3 reinforced concrete walls, [ ] the use of a Derby DB for 5000 users, [ ] the uthe Layerse of SW that has not been updated for 9 years, [ ] the undocumented WAF in the DMZ, . .. .
He also tries to introduce visitors to various events to the joys of the Linux command line (tmux!, vim!, zsh!, fzf!) and collects Austrian IT-fails as well as historical IT systems (still looking for a NeXTcube).
