Install and Configure SFTP server on ubuntu 16.04 (Xenial Xerus) server

Sponsored Link
This tutorial explain how to install SFTP server using MySecureShell on Ubuntu 16.04 server.MySecureShell is a solution which has been made to bring more features to sftp/scp protocol given by OpenSSH. By default, OpenSSH brings a lot of liberty to connected users which imply to thrust in your users. The goal of MySecureShell is to offer the power and security of OpenSSH, with enhanced features (like ACL) to restrict connected users.

How do I get to the next level – Part 2

Advertise here with BSA


I was going over some of the posts of the last year which have had a large number of views and/or comments, just to figure out what interests you folks the most. One of the articles that stood out in terms of number of comments definitely was “How do I get to the next level“. Not just the comments, but I also recall the large number of tweets and feedback I received in person. I just read the article again, and there are a few things which I think I should have probably emphasized more. I figured I would write a follow up… Lets start with a quote from that article.

There is also that thing called “being at the right place, at the right time” and of course seeing opportunities, grabbing opportunities and taking risks.

This phrase was in the first paragraph of the article, and I think it captures a lot more of the essence of success than may seem obvious. A month or so ago I was having a conversation with someone and that person mentioned that in terms of my role within VMware I was lucky to be in the position I am in today. Although I agree that I am very fortunate to have found such a great role, and that there is always luck involved in some shape or form, luck is usually not the reason you are rewarded with a promotion or a new opportunity.

Being at the right place at the right time is one part of it, seeing and grabbing (risky) opportunities is another part. Although you need to be somewhat lucky to have picked the right place and time, one could also argue that it is a skill / talent (like football / hockey players knowing intuitively where the ball / puck will be). Also, don’t worry about failures. Everyone makes mistakes, some pick wrong focus areas, some pick the wrong role or even wrong company to work for, be open and stay alert and assess your position or situation. How is the world (around you) evolving? Is your path leading somewhere? Is this what you expected it to be? Use the information next to make decisions. Do you keep going? Do you need to adapt or even abort and go back to the drawing board?

If I have learned one thing, than it is definitely that I learn the most when I am out of my comfort zone. And if you want to set yourself up for success, you will need to make sure you are capable of adapting fast and learn quick. Learning quick typically happens outside of your comfort zone. Now don’t mistake being out of your comfort zone with being in your panic zone. It is okay to be anxious, to be nervous, to have that jittery feeling… but be aware that this does not turn in to anxiety. Most of you have been in that place at some point in time, you need to do something far far out of your comfort zone, for me that was designing and configuring a network environment (including routing) when I had been responsible for Windows/X86 servers for a couple of years. Way out of my depth for sure back then, which resulted in anxiety and ultimately a failed project. Which leads me to the next skill that will help you grow: Knowing what you know.

But maybe more importantly, knowing what you don’t know and admitting you don’t know. Many people know what they are good/great at, and many will also advertise that broadly. But it is more importantly to understand what your limits and weaknesses are. Knowing that will allow you to understand where you need to grow, and come up with a plan to improve skills / behaviour etc. Also, it will allow you to say “no” when you are out of depth, this is key if you want to set your self up for success, and if you want to grow.

For me personally the one thing that stood out as a weakness (or even lacking skill), when I looked at where I wanted to be and what it would take, was public speaking. I tried it, I failed, no need to pretend, I knew I had to get better at it to grow from a personal perspective, but also from a career standpoint. At a certain level within each organization, presenting is simply required. I was foolish enough to throw myself in at the deep end, my first public speaking experience was at one of the largest conferences (VMworld). That was definitely far outside of my comfort zone and straight in to the panic zone. I should have taken 3 steps back, in hindsight, and started with a small session as a small VMware User Group. Read my article on this, don’t make the same mistake I did… Anxiety doesn’t even come close to describing what I felt. Yes, I did take a step back, reconvened and decided I would never do this again… Well that was my first conclusion. Quickly after that I reached the conclusion that I went too fast, I needed to slow down and take smaller steps. I needed to start with something less nerve wrecking (but still right at the edge of learning and panic zone), which was presenting at a VMUG. Today, I spend most of my time talking to customers or at events, it is safe to say that I have overcome the anxiety. Also, I managed to get really close to where I wanted to be in 3-5 years as a result.

As mentioned in “part 1”, being able to share your thoughts/opinion can make a big difference for your career, whether that is in a meeting / a blog / public speaking is besides the point even. But also speaking up and fighting for something you (strongly) believe in can make a big difference (it did for me). Passion, enthusiasm, energy are all character traits I personally value high and is what I look for when I interview potential candidates. Willingness to take that extra step and go all-in when you believe in something, yet at the same time also know which battle to pick, know when to sit down and listen. That last part is probably the most important, you cannot win them all and you cannot even fight all battles, knowing when to back down is key and an important skill to master. (Is it a skill, or a character trait even?)

Last but not least, perseverance and focus. If you truly want something, focus, make a plan and get things done. Learn from your mistakes and adapt. Don’t be afraid to take a step back and take a different route, even if it will take longer to get where you want to be. As Winston Churchill once said, “Continuous effort, not strength or intelligence, is the key to unlocking our potential.”

Borg Backup – Deduplicating backup program

BorgBackup (short: Borg) is a deduplicating backup program. Optionally, it supports compression and authenticated encryption.The main goal of Borg is to provide an efficient and secure way to backup data. The data deduplication technique used makes Borg suitable for daily backups since only changes are stored. The authenticated encryption technique makes it suitable for backups to not fully trusted targets.

What will it take?

New Westminster has been waiting for a new high school for a very long time. We’ve been told time and time again that a new school is coming, that NWSS is at the top of the Ministry of Education’s priorities, and we just need to be patient.

But should we be patient? Should we trust people who tell us to wait and that the new school is coming?

In 2005 the provincial government announced $52 million in funding for a new school. Demolition actually started, but was halted nearly immediately when workers disturbed asbestos. The school district was fined $75,000 by WorkSafe BC for this. The $52 million disappeared in a similar cloud of dust. (Update: Kelly Slade-Kerr comments below that the asbestos case was actually from a room renovation, not premature school demolition, and that there were other reasons behind the funding disappearing.)

In 2007 board chair Michael Ewen said that there were positive talks with the provincial government and hoped that there would be good news on funding. There was to be no funding.

In June 2015 the school district received a letter from the Ministry of Education saying the ministry “hoped to be in a position to request funding from the provincial treasury within six to eight weeks” and that a funding decision would be announced by November. There was no funding announcement.

On April 4 2016 Mike Bernier, the Minister of Education, said that NWSS was his ministry’s top priority and that a decision would be made in the “coming weeks”. Since then the “number 1 priority right now in the Ministry of Education’s office right now” has been leapfrogged by $149 million in other capital projects and upgrades announced by the Ministry of Education.

New Westminster’s School District 40 and the BC Ministry of Education have problems with deadlines and “trust us” statements. A new high school has been on-again off-again for over a decade. A middle school that was promised to be finished by 2009 not only missed that target, but missed its 2015 opening date as well. Qayqayt Elementary only opened “on time” because of the teachers’ strike that took out the first three weeks of the 2014-2015 school year, allowing them to finish construction. And even then, exterior construction wasn’t finished, and the school was officially opened six months late.

So when Mike Bernier says that an announcement is coming in the “coming weeks”, I don’t trust him. When Mike Bernier says that he hopes to be able to give some certainty before the end of the school year, I don’t believe him. We’ve heard school district chairs say good news is coming for years now.

So what will it take? What will it take for me to believe that New Westminster is getting a new high school?

It won’t be the announcement of funding, because we’ve heard that before.

It won’t be the beginning of demolition, because we’ve seen that before.

At this point the only thing that will make me believe we’re actually getting a new high school in New Westminster is when the first student enters the doors to learn at that new high school.

It’s not that we can’t trust the provincial government. It’s not that we can’t trust the Minister of Education. It’s not that we can’t trust the school district and school trustees.

It’s that they’ve all forced us to not believe in them. Why should now be any different from 2005? Or 2007? Or 2009? You say “trust us” and “be patient”, but why?

Mary Lalji answers my questions!

I asked some questions of the two school trustee candidates in the upcoming by-election, and Mary Lalji answered them!

Question: New Westminster Secondary School is going to be rebuilt one way or another within the next decade. One of the challenges with the site is the Douglas Road Cemetery under the existing high school. When the current NWSS is bulldozed, this will undoubtedly anger the spirits and unleash them on New Westminster. My question for the candidates is this: name three people who will join you as Ghostbusters to save our city.

Answer: The highly trained ghostbusters themselves, Harold Ramis, Dan Aykroyd, Bill Murray of course!

Question: Concussions and other repeated head blows in football and rugby have been shown to be the cause of chronic traumatic encephalopathy (or CTE), leading to player suicides, memory loss, depression, and dementia. The NFL has been sued by ex-players because of this link. High school students are more likely to suffer concussions, and seven died in the US in 2015 from concussion-related injuries. What will you do to ensure the safety of NWSS students playing football, rugby, and other heavy contact sports?

Answer: First of all, there is no rugby program at NWSS, just football and lacrosse as far as contact sports are concerned. Fortunately, my husband Farhan has been on the front lines of the concussion issue for football both at NWSS and provincially and has implemented a number of initiatives to improve the care of the kids playing the sport. Provincially while he was president of the BC Secondary Schools football association, they implemented mandatory baseline testing for all players, adopted a medical policy which included re-return to play protocol, higher standards of medical qualifications for all sideline medical staff, and increased education and awareness for players, coaches and parents. Currently a newly formed safety committee is recommending contact limits during practices, designed to reduce the amount of head contact exposures over the course of a week and season. Locally at NWSS, the football program was the first in BC to purchase a new product called guardian caps, a padded helmet cap used in practice that reduces the force of contact by over 30%. Also, all of our coaches have been certified in the “Safe Contact” program through the Canadian Association of Coaches, teaching contact without using the head. In addition, while some programs have trainers present for only games, our program has qualified people on the sidelines for every practice, and they all take a very cautious approach with potential head injuries. Total number of concussions in 2015 was just 3, and more importantly, NO repeated concussions, which is where the CTE danger come into play.

There is no question that football, like all contact sports, has associated risks, but we are doing everything in our power at NWSS to put our kids in the safest possible position. And it’s also important to note the number of low risk activities that result in head injuries (eg. Cycling, playground, etc) as a recent Vancouver Province article outlines.

Question: Parents in the West End of New West are asking for some sort of solution for getting their children to Fraser River Middle School. This is a two part question: 1. How boring is the name “Fraser River Middle School” on a range of watching paint dry to school trustee by-election? 2. Do you support Queensborough parents of NWSS students in telling West End parents to fuck off?

Answer: 1. Port Coquitlam High School was renamed after Terry Fox, who gave of himself for all after him. Maybe this might be an option in New West for the Fraser River School. 2. You seem like a very brilliant writer. I am sure there are many other more descriptive words to use instead of profanity.

Question: What will you do to ensure parents continue to be punished for daring to have children who get sick?

Answer: As a parent whose kids get sick and that I always get sick from them, I think that is punishment enough.

Question: After NWSS, what do you feel are the priorities for capital projects in SD40?

Answer: There is a Capital plan. Every district must submit a capital needs list on a yearly basis. The ministry has the final say on which of the projects submitted get approved. The next school to be seismically upgraded is McBride and then Howay. Neither has been funded, as yet, by the provincial government.

However every parent should know how safe seismically their school is and you will ask the secretary treasurer to release the information to each school PAC.

Question: What restaurant would you like to see in the Anvil Centre?

Answer: Anything that is really tasty.

There you have it! Thanks to Mary Lalji for answering all of my questions. You can follow Mary on Twitter at @MaryLaljiNW or visit her website at marylalji.ca.

Dee Beattie answers my questions!

I asked some questions of the two school trustee candidates in the upcoming by-election, and Dee Beattie answered them!

Question: New Westminster Secondary School is going to be rebuilt one way or another within the next decade. One of the challenges with the site is the Douglas Road Cemetery under the existing high school. When the current NWSS is bulldozed, this will undoubtedly anger the spirits and unleash them on New Westminster. My question for the candidates is this: name three people who will join you as Ghostbusters to save our city.

Answer: My ghostbuster friends I will invite all of the Lumineers.  I don’t know them personally but their new CD is totally awesome.

Question: Concussions and other repeated head blows in football and rugby have been shown to be the cause of chronic traumatic encephalopathy (or CTE), leading to player suicides, memory loss, depression, and dementia. The NFL has been sued by ex-players because of this link. High school students are more likely to suffer concussions, and seven died in the US in 2015 from concussion-related injuries. What will you do to ensure the safety of NWSS students playing football, rugby, and other heavy contact sports?

Answer: My son played football of of his youth, and luckily he never was seriously injured.  He quit the team when he realized he did not like getting hurt and I was okay with that.

The information is emerging on the injuries and consequences of the injuries that happen in these sports, so I would like to listen to the research and know more before we made big changes in this area. I think I need to listen to the recommendations of experts and doctors on how changes can be implemented.

Question: Parents in the West End of New West are asking for some sort of solution for getting their children to Fraser River Middle School. This is a two part question: 1. How boring is the name “Fraser River Middle School” on a range of watching paint dry to school trustee by-election? 2. Do you support Queensborough parents of NWSS students in telling West End parents to fuck off?

Answer: 1. The Fraser River Middle School.  I totally love the name of this school.  Did you know that I grew up in New West on McDonald St?   Our front room window faced the Fraser River.  My father was a Dutch immigrant to Canada.  His chair sat at the corner of the window facing the river. As a young child I remembered him saying that he was the luckiest man in the world because every day he could look at the most mighty magnificent river in the world.   He felt he had a million dollar view in his $4,000 dollar home.   We had that as a family home for over 30 years.    When my dad died in 1997 my brother and I took a few of his ashes and sprinkled them in the Fraser River.  It was a small tribute to a man who loved that river.  I have no problem with the name of the school.

2. I need to look into this problem and understand it more.  I don’t know what has been done. what planning went into this, and what are some good options.  Tonight I was door knocking in The West End and heard the concerns from many families.  I heard frustration.  A few parents I spoke to have a good solution to get their children to school and a few parents are frantic.  I don’t have the answers to help with this, but I will try my best to understand and appropriately advocate.

Question: What will you do to ensure parents continue to be punished for daring to have children who get sick?

Answer: My background is working in schools, and I think this is a standard policy. I think it is more about protecting the liability of a school district if something goes wrong. Schools are a busy place and if no procedure is put in place it is easy for the safeguards to not be there. To take on the liability of medicating someones child is serious when you have no medical background.

Question: After NWSS, what do you feel are the priorities for capital projects in SD40?

Answer: Seismic Upgrading of all schools is a Priority. Did you know I went to Sir Richard McBride as a child? I would hope to see McBride upgraded and saved. I love bigger older schools. New schools classrooms are small and common areas even smaller. The Stage in the gym disappears in new schools. Having a stage with curtains is like magic to children. The art of Drama belongs on a stage like McBride has! McBride is a Sapperton pride and has valuable heritage. If I can advocate to make that school a lasting piece of history that would be nice!

Question: What restaurant would you like to see in the Anvil Centre?

Answer: I loved taking my 2 boys to ChuckECheese. That could be a great family family fun destination. Just think a restaurant and game centre. ChuckECheese has my vote.

There you have it! Thanks to Dee Beattie for answering all of my questions. You can follow Dee on Twitter at @deelightful or visit her website at deebeattie.ca.
