NetScaler SSH or SFTP Management Access Not Working – SSH Daemon Not Running

Sometimes, especially when NetScaler appliance has been upgraded from previous much older version, could happen that ssh daemon won’t start anymore. This leads to the issue, that you can’t connect to NetScaler management console via SSH or SFTP anymore. Troublehooting this, log in to the NetScaler virtual appliance console from hypervisor or if physical appliance using console port and go to NetScaler Shell. Let’s see if sshd is running or not;

Run: root@NSVPX01# ps ax | grep sshd

If daemon is running, you’ll see ( my example):

5889 ?? Is 0:00.01 /usr/sbin/sshd -f /etc/sshd_config
5910 ?? Ss 0:00.10 sshd: nsroot@pts/0 (sshd)
5931 ?? Ss 0:20.92 sshd: nsroot@notty (sshd)

But, if you can’t see it running, let’s start to troubleshoot it…

Let’s try to start sshd:

Run: root@NSVPX01# /usr/sbin/sshd –f /etc/sshd_config

In my case I got an error (yours might be different, but sshd config file still could be faulty):

/etc/ssh/sshd_config line 10: Deprecated option UsePrivilegeSeparation

So, I need to edit ssh daemon configuration file in etc/sshd_config, because of NetScaler and not normal Linux OS, we have to use lovely VI editor 🙂

Run: root@NSVPX01# cd /etc/
Run: root@NSVPX01# vi sshd_config

In my case I commented out line: “UsePrivilegeSeparation no” to “#UsePrivilegeSeparation” because The UsePrivilegeSeparation is no longer supported (recent SSHD always runs
with previlege separation), so I removed this option from the default config and saved configuration file.

Then let’s try to start ssh daemon again:

Run: root@NSVPX01# /usr/sbin/sshd –f /etc/sshd_config

And sshd started succesfully!

This was just quick tour to quide troubleshooting SSH Daemon errors 🙂

Btw, if you are looking for those ultimate nasty VI Editor commands, take a look this link:

Radically Better Bank Account – The Mobile Bank account!

Traditional banks will charge you when you spend or transfer money, heck they charge you even if you don’t use your account!

Mobile banking is not about that, and that’s why over four million people have switched to Internet banking.

Where it works, in which countries? Everywhere!

Recently, I changed from all my “normal” bank accounts to mobile bank current accounts, in my case I used N26 and Revolut internet banks. Why didn’t I do it before? Probably because all online banks were just in children’s shoes a couple of years ago, but now, wow!

How easy it is to use virtual cards (debit or credit), physical cards are still available as a backup, of course, if the phone or watch is out of power suddenly. All your daily transactions, you’ll use your virtual or physical cards or mobile or web apps.

How easily you open your bank account? In my case a regular UK account and a SWIFT account opening took literally one hour and my ID and account were verified. Why on earth I ever have paid such fees for stoneage banking and get such a bad support and all bureaucracy.

Opening traditional bank account e.g. in UK takes days and you are required to provide all kind of proof-of-something documents before you’ll get your account open. Literally you need to walk in to local branch, your hat on your hand and pray gods you’ll get your account open…. Not anymore!

Transferring money to and from your mobile banking account takes a few seconds instead of days, comparing old stoneage banks. Works with Apple Pay or any other mobile pay applications and acts as a virtual card on your mobile device and now I use only my iPhone or iWatch to pay on stores.

Please, do not hesitate to be in touch if you would like to know more about this and follow my links to open your internet banking account in a minutes.

Use links below to open your own N26 and/or Revolut account immediatelly!

Citrix Cloud Service On-boarding and Cloud Connectors Guide

Citrix Cloud Service On-boarding and Cloud Connectors Guide

Lately I delivered project to consolidate global multi-site on-premises environments in to one and migrate it to the Citrix Cloud Services. This time it included multiple different vendor’s Enterprise Mobile Management solutions (XenMobile, Workspace ONE, etc.) and Citrix ADCs (NetScalers). Multiple different MDM solutions migrated in to Citrix Endpoint Management service in to Citrix Cloud.

I’m not going to go any more technical details regarding different vendor’s products as this time this is not meant to be technical post, (that will come later!), but rather I walkthrough process how to get on-boarded in to Cloud Service and install Citrix Cloud Connector.

INFO: Citrix Cloud services simplify the delivery and management of Citrix technologies, helping you to extend existing on-premises software deployments or move one hundred percent to the cloud.  Create and deploy secure digital workspaces in hours, not weeks, while placing your sensitive app, desktop and data resources on any cloud or hybrid cloud.

There is two different approach for Citrix Cloud Services, Transition and Migration. I’m focusing now on this post in to Transition approach, as the Migration approach always requires to engage Citrix Sales and Professional Services who helps to migrate databases etc. from on-premises.

Migration advantages are to copy current configuration, databases, etc. as it is and like for XenMobile, users are not required to re-enroll their devices again in to cloud service. Migration will be seamless for the users.

Transition approach is a clean new services will be created in Citrix Cloud from scratch and users will be migrated to use the new cloud based services. It has advantages like housekeep and inventory of current environment, but also current on-premises environment and cloud services parallel during user migration. Disadvantage could be require to build a new/similar environment from the scratch, which still is not always disadvantage.

Both approaches have its advantages and challenges and needs to be carefully chosen based on customer requirements, scenarios and products to be migrated.

Everything starts from the assessment, gather current on-premises environment details, use cases, expectations, prerequisites and limitations. Then decide right on-boarding method for the customer.

Next step is to subscribe the Cloud Service platform and get it up and running, ready to be for a new service or for migration of current services.

Go to the Citrix Cloud On-boarding website: and use current account details or register there depending if it is a new or existing customer.

Other helpful method is to get in contact to Citrix Sales Engineer in your region and ask them to advice.

After successfully registration customer are able log in to: and request service trials. This is the portal in where to manage all Citrix Cloud Services, open service tickets, etc.

Customer can click Request Trial to formally request a trial for the services. Once the customer requests the trial it must be approved by the Cloud Services Rapid Deployment Team or Cloud Product manager.

Citrix Cloud Connector

After successfully requested trials and got them up and running, first thing probably would be to connect Cloud Services to on-premises for Active Directory user authentication etc.

The Citrix Cloud Connector is a Citrix component that serves as a channel for communication between Citrix Cloud and on-premises resource locations, enabling cloud management without requiring any complex networking or infrastructure configuration. This removes all the hassle of managing delivery infrastructure. It enables customer to manage and focus on the resources that provide value to your users. E.g. Active Directory authentication from Cloud Services to on-premises domain. Cloud Connectors also replaces Virtual Apps and Desktops Desktop Delivery Controllers (DDC) role and acts as the control point for the VDA’s on-premises.

The Virtual Apps and Desktops and Citrix Endpoint Management services requires the Cloud Connector for enterprise connectivity to the Endpoint Management service.

Cloud Connector is a small software cwcconnector.exe to be installed to domain joined on-premises Windows Server. Two servers are recommended to be installed for sake of High-Availability.

Download Cloud Connector software from the Cloud Portal Resource Locations page.

NOTE: Do not install the Cloud Connector, or any other Citrix components, on an Active Directory domain controller.

Do not install the Cloud Connector on machines that are part of other Citrix deployments (for example, Delivery Controllers in a Virtual Apps and Desktops deployment).

Cloud Controller Technical Requirements

  • Supported on Windows Server 2012 R2 and Windows Server 2016.
  • .NET Framework 4.5.1 or later.
  • Active Directory (AD): Join the machine to an AD domain that contains the resources and/or users for the workspaces (Active Directory schema versions 2008 R2 and later are supported).
  • Networking: Connect the machine to a network that can contact the resources in the Resource Location. These resources provide the services of the cloud workspace. The machine must have a connection to the internet.
  • Make sure the clock on the server has the correct time. Otherwise, you cannot connect to the cloud.
  • The connector requires outbound connectivity on port HTTPS 443.

Cloud Connector Install Instructions

  1. Log on as an administrator to the machine where you will install the Cloud Connector. The machine should have Windows Server 2012 R2 or Windows Server 2016 installed, be joined to a domain, and have outbound Internet access. (HTTPS 443)
  2. Go to and sign in. The Citrix Cloud management console appears.
  3. From the menu button in the upper left corner, select Resource Locations.
  4. On the Resource Locations page, click Download to download the Cloud Connector software.
  5. Launch the Cloud Connector installer. The installer performs an initial connectivity check to ensure you can connect to Citrix Cloud.
  6. When prompted, sign in to Citrix Cloud.
  7. Follow the wizard to install and configure the Cloud Connector. When the installation finishes, the installer performs a final connectivity check to verify Connector-to-Cloud communication.
  8. Repeat these steps on additional machines you want to use as Cloud Connectors.

After installation go back to the Cloud Portal and Resource Locations, you should see the Cloud Connector successfully connected.

The Cloud Connector authenticates and encrypts all communication between Citrix Cloud and on-premises resource locations. Once installed, the Cloud Connector initiates communication with Citrix Cloud through an outbound connection. All connections are established from the Cloud Connector to the cloud using the standard HTTPS port (443) and the TCP protocol. No incoming connections are accepted.
