Gmail SMTP 2 Factor Authentication on OSX iMail

The following method has worked for me when it comes to sending emails via SMTP using Google Apps Account with Two Factor Authentication (2FA) enabled. I am sure this method can also be followed for regular Gmail Accounts.

On Your Google Accounts

  1. Revoke the Application Specific Password for iMail
  2. Create a New Application Specific Password for iMail

On Your Mac

  1. Go to Keychain Access and Delete smtp.gmail.com
  2. On iMail Change the Outgoing Mail Server (SMTP) by selecting the Edit SMTP Server List and click the Advance tab
  3. Make sure the Username is your Email Address and the Password is the one you have generated on the above step.
  4. iMail will prompt for the SMTP server confirmation along with a prompt for a password, make sure to use the one which was generated on the above list.

Is SecureCRT worth it?

You are probably here becasue you have asked the same question as I did before purchasing SecureCRT: Is it worth me forking out $100 for a terminal emulator software?

This is probably one of the question every Network/Systems Engineer asks when it comes to buying a terminal emulator, or stick with freeware like Putty/TeraTerm etc on Windows, iTerm2 on Mac and Terminal on Linux.

There is a great post covered by Greg Ferro here, where he iterates that is it not good value for money. I do agree with him 100% where you could get such application on Mac App Store for around $25. However, when it comes to evaluating a software or any matter, one needs to consider the individual requirement before committing themselves financially to the purchase.

There are a number of questions I have asked myself before going ahead with the purchase…

Android Push / WhatsApp Messages are getting delayed with connected to Wi-Fi Router. Messages get delivered when the phone screen is turned on.

I have managed to reproduce the problem and it turned out to be a Wi-Fi chip issue on the device(s) itself.

This is because the Phone in question (Nexus 4) stops responding to ARP request when the phone is on Sleep mode. This is due to Qualcomm Prima WLAN issue which affects all phones with this specific chip…

Only way to currently fix it is to add a Static ARP entry onto the Router. Given that it is supported on the router itself. Alternatively you can use Android Notification Fixer from the Play Store but for that to work, the phone needs to be rooted.

Please make sure you have Static IP / DHCP entry configured to the given IP(s), before adding the Static ARP entry

How to speed up DSL Connection

I have been working on some xDSL sync issues and and here are some of my findings to boost the xDSL Sync rate and have a stable line.

Option 1

First of all, make sure which standard your ISP’s DSLAM running on. This is important because some standards have limitations which will create a bottleneck when it comes to the hardware you are using. First rule of thumb for people who are not sure is to use the ISP’s provided hardware.

For example ITU G.992.5 (ADSL2+) will have an upload limitation of 1.3 Mbps, you might have a line which is capable of handling more than 1.3 Mbps but the hardware you use will cause a limitation. This is why you need to make sure which standard the ISP is running the DSLAM on. If the ISP happen to run ITU G.992.5 Annex M (ADSL2+ M) you are likely to get an upload speed of more than 1.3 Mbps, thus having a router which is capable of supporting Annex M will be beneficial.

How Reliable is your Hard Disk?

If I ask that question to a number of people, I have a feeling I would get all sorts of answers. I think, Hard Disk reliability doesn’t necessarily depends on the manufacturer but it also depends on how it has been treated in a machine. In my opinion, a HDD in a machine with multiple power cuts would most likely have a short lifespan than one run with proper care.

Lets talk about the Manufacturer…

People have preference when it comes to HDD Manufacturer. When it comes to the manufacturer, I tend to go for Western Digital (WD) and solely because I had less bad experience with it compared to Maxtor…

I am not saying WD drives never fails, in fact I do have an old WD 80GB IDE drive here which died this morning; but it does have low percentage of failure.

Why does it die?

One person actually asked me this question and the answer is very simple. Any electronic equipment, or any functioning part will die at one point, its the same as human body, it all depends on how its been treated the background of it. When it comes to HDD, its the manufacturer.

How to stop a HDD from dying?

You can’t and you never know when it’s going to die, same as a human being… You never know when you are going to die. It all comes down to to proper care and how its been treated. For example, do not shut your machine down by pulling the plug, it WILL kill the HDD at one point! If you want to shut it down without doing it via the Operating System, press and hold the Power Button for 10 seconds and it should shut the machine down.


Treat a HDD like it is going to die the next minute and back it up on a regular basis. If you don’t have any important information on the disk, then it not a problem. You could either manually back it up on another drive, setup RAID on machine or even back it up to a remote server.

Should UK Monitor Internet Activities

This is a controversial question among people whether UK should monitor all Internet and communication activates like the USA. When this subject is brought up, people automatically go on the defensive and starts to argue the fact about privacy and human rights; Granted, privacy is a major issue, and when it involves national security, it will spark some inimitable questions among us.

I am not in favour of the Government breaching privacy and human rights issues; on the contrary, in my opinion, national security should be given priority among other things.

This is a very sensitive issue and when this subject is brought up, people seem to think that all their internet activities are going to be watched, including their internet shopping. This is not the case here, and if the government goes ahead and do such monitoring system, it will cost billions.

I think the word monitoring should be redefined when it comes to this topic and should be balanced in a way that it does not interfere with people’s privacy issues, thus a flagging system to use for such monitoring would an ideal choice. This way, people’s privacy won’t be compromised and at the same time it would allow the government to monitor the internet.

All we see in the news lately is terrorist activities directly linked to the internet and how they used the net to communicate with each other. So, if such system was in place, in theory the chances of stopping such thing would be extremely high.

I think it’s safe to say, UK should monitor all Internet and communication activities so they can rule out terrorism in their home soil.
