Brocade 6450, frustration

August 16, 2018

Well a company named Ruckus bought Brocade. Fine. Business world etc. I understand. They renamed Brocade ICX 6450 to Ruckus ICX FastIron 6450 or maybe just Ruckus ICX 6450. It is hard to find out.

To download an update for the switch is … not an easy job. To find the documentation is not an easy job either. These people from Ruckus did a bad job. BAD!

Took me about forever to discover what I was looking for. It is very simple:

• Autokey public key authentication is not supported.

and that line could be found in the documentation. I’ll try to attach it here, otherwise currently could be found after series of logins, password resets, etc at

How to mute ringer on iPhone

February 22, 2016

Finally Apple started to support their own keyboard the way it suits me, meaning pressing “enter” sends an imessaage/sms. Took them several years.

Anyway, when I was playing with the keyboard I found out when I press “mute”, it mutes the phone completely without pressing the side (mute) switch, but when I tried to do that from the phone, took me about forever to find a way. So below is my way.

I assigned “mute” to my assistive touch (which is under settings/general/accessibility/assistive touch/custom top level menu) and assigned “assistive touch” to my “accessibility shortcut” (which is under settings/geneal/accessbility at the very bottom).

Right now when I press my home button three times, brings “assistive touch” menu and once pressed I’m getting software button which mutes or unmutes my ringer/volume. Pressing the home button three times again, allows me to remove the “assistive touch” software button, so it doesn’t bother me.

Why do I do it that way? Variety of reasons from a broken side mute button to my case, which literally is the case… it is outter box heavy duty, and every time i need to mute the phone have to dig and open the side with my nails or a key, which is a pain and the case becomes loose after a while doing that.

So I hope you like my solution and use it from time to time. I didn’t find anything clear on google, so I wrote it down in order to help to someone like me.

Thank you.

Snorby: Debug the mailing feature and creating cron job

November 4, 2013

Do not run the following commands unless you really need to:

cd /path/to/snorby

bundle exec rails c production
Snorby::Jobs::DailyCacheJob.new(true).perform (this command is invalid for version 2.6.2)

I tried a few things. From the shell of my CentOS 6.4 everything works fine but can’t make it automatically to send me reports, so I didn’t bother to go ahead with the source but just added that simple file (named snorby_report.cron) in /etc/cron.daily:

cd /path/to/snorby
RAILS_ENV=production /usr/bin/rails r ‘Snorby::Jobs::SensorCacheJob.new(true).perform’
