Infocom Security Conference 2017 – On the IT Roadmap EXPECT the UNEXPECTED


The curtain of 7th Infocom Security Conference just fall down yesterday. The conference highlighted the need of Network, System and Information Security in our lives since it depends more and more on digital assets. The European General Data Protection Regulation (GDPR) is defining the general framework of information security and almost 90% of the companies should comply with in the following 12 months.

I just place a few photos from the main conference room and some workshop sessions.


Cisco Roadshow 2017 in Athens – Reimagine your Business


Yesterday, Cisco organised the Roadshow 2017 in Athens entitled “Reimagine your business”.The agenda was short, not deeply technical but absolutely interesting. The audience filled up the whole event room.


I must admit that I love Cisco events! What I like in these events is that Cisco looks ahead, tries to predict the future and adapts to it (or creates it). And this process is visible to the audience and it convinces me that Cisco is here and it will stay here.

Let’s see some pictures from the event. Mr. Antonis Tsimboukis, the general manager of the local  Cisco branch was the first speaker.


And this guy is Mr. Oren Seliger, who gave an absolutely great speech about Cisco’s view of the future. I will only mention the two quotes that he said during his speech, the combination of these shows Cisco’s philosophy.

He mentioned that

Shimon Peres said “Change is nothing to fear. Don’t be afraid of change. Don’t expect change but pursue change” and

Abraham Lincoln said “The best way to predict the future is to create it”

This is Cisco’s way of thinking…


The rest of the speakers where very good as well. The main keypoints were the following:

  • Panagiotis introduced Hyperflex data platform, that it seems to be a very good choice for SMEs entering into the virtualised world. It is VMware compatible right now and it supports local disks in a low cost configuration or an external storage.
  • Chara touched two issues about how easily network Cisco devices can be centrally managed and how network data analytics may help a business to take optimized key business decisions.
  • Nikos confirmed Cisco’s security commitment and announced that Cisco enters into endpoint security arena using Talos for threat analysis
  • And Alkis announced Spark, Cisco’s new collaboration platform, supported by video conferencing devices and Spark board, a new device for digital white boarding.

What a great day I had yesterday. As a final word, I would shout “Pursue change at personal level and create your future”.

Reactivate a broken IMAP service on Microsoft Exchange 2013/2016

And one day, suddenly, IMAP service stopped working properly on my Exchange 2013 mail server.

Usually by telneting to imap port, exchange server returns a banner.


When the IMAP service is broken, the telnet screen is blank and the connection aborts. The initial idea to restart the IMAP services on the exchange does not fix the problem. (In this case all the exchange roles reside on the same server)


Run the following command on a powershell window

Get-HealthReport <servername>  | where { $_.state -eq “Offline”}

It will return an offline IMAP.Proxy healthstate.


Usually this is a Microsoft bug, since it appears after installing a Cumulative Update on the Exchange Server. By setting online the IMAPProxy, the IMAP service comes into life. Run the following command:

Set-ServerComponentState -Identity <servername> -Component IMAPProxy -State Active -Requester HealthAPI
